(AP) ? Catholics and Protestants flocked to churches to celebrate Easter on Sunday in the Holy Land and across the broader Middle East, praying, singing and rejoicing.

Some Mideast Christian communities are in a flux, while others feel isolated from their Muslim-majority societies. In places like Iraq, they have sometimes been the victims of bloody sectarian attacks.

At St. Joseph Chaldean Church in Baghdad, some 200 worshippers attended an Easter mass that the Rev. Saad Sirop led behind concrete blast walls and a tight security cordon. Churches have been under tighter security since a 2010 attack killed dozens.

"We pray for love and peace to spread through the world," said worshipper Fatin Yousef, 49, who arrived immaculately dressed for the holiday. She wore a black skirt, low-heeled pumps and a striped shirt and her hair tumbled in salon-created curls.

It was the first Easter since the election of Pope Francis and she and others expressed hope in their new spiritual leader. "We hope Pope Francis will help make it better for Christians in Iraq," she said.

In Jerusalem, Catholics worshipped in the church of the Holy Sepulcher, built on a hill where tradition holds that Jesus was crucified, briefly entombed and then resurrected. The cavernous, maze-like structure is home to different churches belonging to rival sects that are crammed into different nooks and even the roof.

Clergy in white and gold robes led the service held around the Edicule, the small chamber at the core of the church marking the site of Jesus' tomb. Many foreign visitors were among the worshippers.

"It's very special," said Arthur Stanton, a visitor from Australia. "It represents the reason why we were put on this planet, and the salvation that has come to us through Jesus."

Israel's Tourism Ministry said it expects some 150,000 visitors during holy week and the Jewish festival of Passover, which coincide this year. It is one of the busiest times of the year for the local tourism industry.

Protestants held Easter ceremonies outside Jerusalem's walled Old City at the Garden Tomb, a small, enclosed green area that some identify as the site of Jesus' burial. Another service was held at the Church of the Nativity in Bethlehem, Jesus' traditional birthplace.

Catholics and Protestants, who follow the new, Gregorian calendar, celebrate Easter on Sunday. Orthodox Christians, who follow the old, Julian calendar, will mark it in May.

There are no precise numbers on how many Christians there are in the Middle East. Census figures showing the size of religious and ethnic groups are hard to obtain.

Christian populations are thought to be shrinking or at least growing more slowly than their Muslim compatriots in much of the Middle East, largely due to emigration as they leave for better opportunities and to join families abroad. Some feel more uncomfortable amid growing Muslim majorities that they see as becoming more outwardly pious and politically Islamist over the decades.

The situation for some Mideast Christians is in flux.

In Syria, Christians, who make up some 10 percent of the country's 23 million people, have mostly stayed on the sidelines of the two-year civil war. While outraged by the regime of Bashar Assad's brutal efforts to quash the opposition, they are equally frightened by the Islamist rhetoric of many rebels and their heavy reliance on extremist fighters.

Christians make up some 10 percent of Egypt's 85 million people. Human rights groups say the police under former authoritarian leader Hosni Mubarak rarely took the needed steps to prevent flare-ups of violence against Christians, a situation that persisted since he was overthrown in 2011. The rise of Islamists in Egypt has emboldened extremists to target churches and Coptic property, leading to a spike in attacks and sometimes unprecedented steps like the evacuation of entire Christian populations from villages.

In Libya, most Christians are Egyptian laborers who are working in the oil-rich country. Tensions rose last month after assailants torched a church in the eastern city of Benghazi and militias arrested some 100 Christians, mostly Egyptian, accusing them of proselytizing.

In Iraq, Christians have suffered repeated attacks by Islamic militants since the 2003 U.S.-led invasion, and hundreds of thousands have left the country. Church officials estimate that the Christian communities have shrunk by at least half. The worst attack was at Baghdad's soaring Our Lady of Salvation church in October 2010 that killed more than 50 worshippers and wounded scores of others.

There currently are an estimated 400,000 to 600,000 Christians in Iraq, with most belonging to ancient eastern churches. Some two-thirds of Iraq's Christians are Catholics of the Chaldean church and the smaller Assyrian Catholic church. Members of both churches chant in dialects of ancient Aramaic, the language that Jesus spoke.

Yousef, the worshipper in Baghdad, said lingering fear pushed her to send her son to live with relatives in Arizona last year. Yousef said she was arranging for her other daughter and son to immigrate.

"There's still fear here, and there's no stability in this country," she said.

Iraqi officials have made efforts to secure churches since the violence of 2010.

High blast walls topped with wire netting and barbed wire surrounded the St. Joseph Church in Baghdad's middle-class district of Karradeh. Four Iraqi Christian volunteers stood at the church entrance, double-checking the people entering. And blue-khaki clad Iraqi police guarded roads surrounding the church and checked papers of passers-by as worshippers filed inside.

White-robed church volunteers marched down the church aisle behind Father Sirop, who waved incense and chanted in the white-painted church adorned with three ornate chandeliers and a series of simple paintings illustrating the life of Christ.

Worshippers stood for lengthy passages of Sirop's mass, at one point bursting into applause when he told them, "Celebrate! You are Christians!"

A gourmet food company is recalling three of its ?dairy-free? baking mixes because they might contain milk, according to the U.S. Food and Drug Administration.

Heartland Gourmet, based in Lincoln, Neb., announced the voluntary recall Thursday after routine sample testing in Canada uncovered milk in some cookie and pizza crust mixes, which are labeled both gluten-free and dairy-free.

The recall notice cites ?a temporary breakdown in the company?s production and packaging processes? leading to the contamination, but a company spokeswoman said the problem is still under investigation.

Milk is one of the most common food allergens, according to the National Institute of Allergy and Infectious disease. It can cause hives, wheezing and vomiting, as well as abdominal cramps and diarrhea. In rare cases, milk can cause anaphylaxis, a life-threatening reaction.

17 Scary Allergy Triggers

An ABC News analysis in?December?2012 revealed that more than 400 recalls for undeclared allergens in food were reported to the FDA since March 2009. More than 140 of them were for desserts and snack foods, including cookies, candy and ice cream.

The Heartland Gourmet?mixes were distributed to stores in Minnesota, Texas, Indiana, Connecticut, North Carolina, California and Colorado between October 2012 and March 2013, according to the recall notice. The company also supplies mixes for fundraisers, according to its website. No illnesses have been reported to date.

The recalled products include:

  • Gluten Free Chocolate Chip Cookie Mix: Item # 2017 UPC Code 7376967020171 16 oz. Lot #0023065, best buy date of 12/2014 and distributed in March of 2013, and Lot # 0023007, best buy date of 10/2014 and distributed in February 2013.

Apple sued by Chinese animation studio over pirated materials in apps

Apple sued by Chinese animation studio over pirated materials in apps

Apple is being sued by a state-run animation studio in China over apps that contain unlicensed material from the studio. Shanghai Animation Film Studio is seeking total damages of 3.3 million yuan, or $530,000. The studio says that Apple violated the copyright of 110 of their films, which resulted in siginificant financial losses for the studio. According to M.I.C. Gadget:

The studio found Apple selling pirated copies of their works back in July last year, causing huge economic losses to the company while bringing profits to Apple as well as the application developers. Allegedly, a Chinese court has accepted the case, but there?s no details on when the first hearing will be.

This is another in a recent string of legal problems for Apple in China. They previously lost a similar case regarding unauthorized distribution of a Chinese encyclopedia. Additionally, they have been sued by a company claiming that Siri violates one of their patents. Last year, they were ordered to pay Proview $60 million over the Chinese trademark for the iPad.

North Korea says it is entering 'state of war' with South

Baengnyeong Island, which is home to 5,000 South Korean civilians and many soldiers, sits just ten miles from the North Korean border. Despite escalating tensions, most islanders seem determined to stay put while keeping an eye on their neighbors. NBC's Ian Williams reports

By Marian Smith, Staff Writer, NBC News

North Korea said on Saturday that it was entering a "state of war" with South Korea, following a call to arms by the country's young leader Kim Jong Un and days of increasingly belligerent rhetoric from the isolated state.

The North's official news agency KCNA published the joint statement issued by the government, political parties and other organizations.

"From this time on, the North-South relations will be entering a state of war and all issues raised between the North and the South will be handled accordingly," it said.?

The statement also warned that if the U.S. and South Korea carried out a pre-emptive attack, the conflict "will not be limited to a local war, but develop into an all-out war, a nuclear war."

Analysts have said the North's threats have followed a similar pattern but that the country's 30-year-old leader is unpredictable and potentially dangerous.

The White House responded on Saturday by reiterating that "North Korea has a long history of bellicose rhetoric and threats," National Security Council spokeswoman Caitlin Hayden said in a statement. However, she said the U.S. "takes these threats seriously".

"We continue to take additional measures against the North Korean threat, including our plan to increase the U.S. ground-based interceptors and early warning and tracking radar, and the signing of the ROK-U.S. counter-provocation plan," she said.

David Guttenfelder / AP

As chief Asia photographer for the Associated Press, David Guttenfelder has had unprecedented access to communist North Korea. Here's a rare look at daily life in the secretive country.

On Thursday the U.S. sent two nuclear-capable bombers to South Korea, where they dropped inert munitions in a military exercise. The flight sparked an angry response from the North, which declared on Friday that it was preparing rockets aimed at American bases in South Korea and the Pacific.

"We take these threats seriously and remain in close contact with our allies in South Korea," said Caitlin Hayden, a spokesperson for the National Security Council. The response comes as leader Kim Jong Un declared a "state of war" on South Korea. NBC's Kristen Welker reports.

A South Korean defense ministry official said there were no early signs that the North was mobilizing, Reuters reported.

The two nations have technically been at war since a truce ended their 1950-53 conflict, but tensions have been increasing since the North carried out its third nuclear weapons test in February.

NBC News' Kristen Welker and Reuters contributed to this report.

Russian tycoon found dead in Britain: Is it suicide?

Russian tycoon found dead: Boris Berezovsky was found in his Surrey, England, home, dead. Cause of death is not known yet. But there is speculation that the once-wealthy Russian tycoon committed suicide.

The cause of death is unknown at this time. But speculation that Berezovsky committed suicide is rampant, especially in Russian media.

Two things are prompting the speculation. First, a Russian lawyer, Alexander Dobrovinsky, was among the first to announce his death and posted in social media the following, according to RT.com:

?Just got a call from London. Boris Berezovsky committed suicide. He was a difficult man. A move of disparity? Impossible to live poor? A strike of blows? I am afraid no one will get to know now,?

There's no indication of the quality of Dobrovinsky's source. Certainly, British police have not yet made public a cause of death.

The second factor fueling the suicide talk is the very public decline in Berezovsky's wealth. He had lost several court cases and was known to be selling off real estate, a yacht, and art to raise funds. As The Guardian of London reports:

"Berezovsky's death comes only months after he lost a high-profile and personally disastrous court case against fellow Russian oligarch Roman Abramovich. He had accused the Chelsea football club owner of blackmail, breach of trust and breach of contract in relation to a Russian oil company. After the claims were dismissed, he was ordered by the high court to pay ?35m of Abramovich's legal costs.

His financial difficulties were recently further exacerbated after his former mistress Elena Gorbunova, 43, claimed that Berezovsky owed her $8m (?5m) in compensation over the sale of their $40m residence in Surrey."

Just days ago, Berezovsky sold his Andy Warhol limited edition print of Vladimir Lenin, known as "Red Lenin," for just over $200,000, according to the Russian media outlet RIA Novosti.

Berezovsky's political and financial success follows the arc of recent Russian history. In the 1980s, with the political opening and rise of free enterprise, he went from a quiet mathematician to powerful oligarch. His first business foray? - which Russian prosecutors later said was? illegal profit skimming - involved car sales for the state auto giant AvtoVAZ. Berezovsky used his initial wealth to build a media empire that included partial ownership of two national television networks and several respected newspapers.

As his wealth grew, so did his political clout.

In 1996, Berezovsky was among a group of businessmen who helped Boris Yeltsin's career. "It is no secret that Russian businessmen played the decisive role in President Yeltsin's victory," Berezovsky later told Forbes magazine. "It was a battle for our blood interests."

In return, Yeltsin sold to his backers Russian national industries at a fraction of their actual value. By the late 1990s, Berezovsky had an 80 percent ownership share in Sibneft, an oil company.

But as Agence France Presse reports "his most significant political move was the one that inadvertently sealed his fate: helping Yeltsin choose then-secret services chief Vladimir Putin as Russia's second president.

Berezovsky quickly became a key target of Putin's crackdown on the oligarchs' political independence. He fled the country and fired back with his entire media arsenal, painting the new president as a budding dictator."

The Guardian notes that "Berezovsky is been on Moscow's most wanted list since 2001 on charges of fraud, money-laundering and attempted interference in the Russian political process. A Russian court sentenced Berezovsky in absentia for embezzling $2bn from two major state companies."

But in the past year, there are reports that Berezovsky was seeking to return to Russia. The Irish Times reports that he had recently written to Mr. Putin seeking a pardon, according to Putin's spokesman Dmitry Peskov.

South Africa's Mandela "responding positively" to treatment

By Ed Stoddard

JOHANNESBURG (Reuters) - Former South African President Nelson Mandela is "responding positively" to treatment for a recurring lung infection after being admitted to hospital overnight, the government said on Thursday.

"He remains under treatment and observation in hospital," it added in a statement, without giving further details about the health of the 94-year-old anti-apartheid leader.

Mandela, who became South Africa's first black president in 1994, has been mostly absent from the political scene for the past decade, but remains an enduring and beloved symbol of the struggle against racism.

He is renowned at home and abroad for spending 27 years in prison fighting the last bastion of white rule in Africa and then promoting the cause of racial reconciliation.

"Black Americans look up to him because he fought oppression and his bravery is something that doesn't happen often," said Yau Williams, an American tourist, as he walked through Johannesburg's financial district of Sandton.

Mandela has been frail and in poor health for several years.

"He will come out fine, let's just have faith in God," said Samson Ndlovu, speaking in Zulu as he walked out of a Johannesburg taxi rank.

Mandela was in hospital briefly earlier this month for a check-up, and spent nearly three weeks in hospital in December with a lung infection and after surgery to remove gallstones.

That was his longest stay in hospital since his release from prison in 1990 after serving almost three decades for conspiring to overthrow the white-minority apartheid government.

Mandela has a history of lung problems dating back to when he contracted tuberculosis as a political prisoner.

As he has receded from public life, critics say his ruling African National Congress (ANC) has lost the moral compass he bequeathed it when he stepped down as president in 1999.

Under such leaders as Mandela, Walter Sisulu and Oliver Tambo, the ANC gained wide international respect as it battled white rule. Once the yoke of apartheid was thrown off, it began ruling South Africa in a blaze of goodwill from world leaders who viewed it as a beacon for a troubled continent and world.

Almost two decades later, this image has dimmed as ANC leaders have been accused of indulging in the spoils of office, squandering mineral resources and engaging in power struggles.

Mandela spent much of last year in Qunu, his ancestral village in the poor Eastern Cape province. But since his release from hospital in December he has been at his home in an affluent Johannesburg suburb, closer to sophisticated medical facilities.

CU study provides new evidence ancient asteroid caused global firestorm on Earth

Fires would have burned every twig, bush and tree on Earth

A new look at conditions after a Manhattan-sized asteroid slammed into a region of Mexico in the dinosaur days indicates the event could have triggered a global firestorm that would have burned every twig, bush and tree on Earth and led to the extinction of 80 percent of all Earth's species, says a new University of Colorado Boulder study.

Led by Douglas Robertson of the Cooperative Institute for Research in Environmental Sciences, or CIRES, the team used models that show the collision would have vaporized huge amounts of rock that were then blown high above Earth's atmosphere. The re-entering ejected material would have heated the upper atmosphere enough to glow red for several hours at roughly 2,700 degrees Fahrenheit -- about the temperature of an oven broiler element -- killing every living thing not sheltered underground or underwater.

The CU-led team developed an alternate explanation for the fact that there is little charcoal found at the Cretaceous-Paleogene, or K-Pg, boundary some 66 million years ago when the asteroid struck Earth and the cataclysmic fires are believed to have occurred. The CU researchers found that similar studies had corrected their data for changing sedimentation rates. When the charcoal data were corrected for the same changing sedimentation rates they show an excess of charcoal, not a deficiency, Robertson said.

"Our data show the conditions back then are consistent with widespread fires across the planet," said Robertson, a research scientist at CIRES, which is a joint institute of CU-Boulder and the National Oceanic and Atmospheric Administration. "Those conditions resulted in 100 percent extinction rates for about 80 percent of all life on Earth."

A paper on the subject was published online this week in the Journal of Geophysical Research-Biogeosciences, a publication of the American Geophysical Union. Co-authors on the study include CIRES Interim Director William Lewis, CU Professor Brian Toon of the atmospheric and oceanic sciences department and the Laboratory for Atmospheric and Space Physics and Peter Sheehan of the Milwaukee Public Museum in Wisconsin.

Geological evidence indicates the asteroid collided with Earth about 66 million years ago and carved the Chicxulub crater in Mexico's Yucatan Peninsula that is more than 110 miles in diameter. In 2010, experts from 33 institutions worldwide issued a report that concluded the impact at Chicxulub triggered mass extinctions, including dinosaurs, at the K-Pg boundary.

The conditions leading to the global firestorm were set up by the vaporization of rock following the impact, which condensed into sand-grain-sized spheres as they rose above the atmosphere. As the ejected material re-entered Earth's atmosphere, it dumped enough heat in the upper atmosphere to trigger an infrared "heat pulse" so hot it caused the sky to glow red for several hours, even though part of the radiation was blocked from Earth by the falling material, he said.

But there was enough infrared radiation from the upper atmosphere that reached Earth's surface to create searing conditions that likely ignited tinder, including dead leaves and pine needles. If a person was on Earth back then, it would have been like sitting in a broiler oven for two or three hours, said Robertson.

The amount of energy created by the infrared radiation the day of the asteroid-Earth collision is mind-boggling, said Robertson. "It's likely that the total amount of infrared heat was equal to a 1 megaton bomb exploding every four miles over the entire Earth."

A 1-megaton hydrogen bomb has about the same explosive power as 80 Hiroshima-type nuclear bombs, he said. The asteroid-Earth collision is thought to have generated about 100 million megatons of energy, said Robertson.

Some researchers have suggested that a layer of soot found at the K-Pg boundary layer roughly 66 million years ago was created by the impact itself. But Robertson and his colleagues calculated that the amount of soot was too high to have been created during the massive impact event and was consistent with the amount that would be expected from global fires.

Energy policies 'reduce bill rises'

Government policies on energy efficiency and climate change are helping to reduce the rise in gas and electricity bills, a report has said.

By 2020, bills will be 11% - or ?166 - lower than they would otherwise have been, according to the Department of Energy and Climate Change's report.

The report said policies could add costs to bills - but overall they help cushion households against rises.

Labour accused the government of masking the effect of its policies.

Downward trend

Savings generated from policies, such as helping to insulate homes and promoting the installation of more energy efficient boilers, are already having an impact and will increase over the next decade, the report said.

Household dual fuel bills are estimated to be on average 5% - or ?64 - lower now than they would be without these policies, it said.

Nearly half of the average household dual fuel energy bill, or about 47%, is made up of fossil fuel prices, or ?598, with the second largest cost attributed to network costs or transport and distribution of energy, at 20%, or ?257.

Government policies on energy and climate change account for 9%, or ?112 of this bill - with ?30 of this spent on renewable energy policies, including ?9 on on-shore and ?9 on off-shore wind.

We are doing all we can to offset these global energy price rises?

End Quote Ed Davey Energy and Climate Change Secretary

More than half of the energy and climate change policy costs in household bills are are spent on measures to target the fuel poor and energy efficiency.

The report showed that 85% of the rise in household bills between 2010 and 2012 was from wholesale energy costs and network costs and 15% as a result of government policies.

Household energy consumption has been on a downward trend since 2005, partly as a result of energy efficiency measures already in place, according to the report.

By 2020 around 12 million boilers will have been replaced with more energy efficient models, it said.

Energy and Climate Change Secretary Ed Davey said: "Global gas price hikes are squeezing households. They are beyond any government's control and, by all serious predictions, are likely to continue rising.

"We are doing all we can to offset these global energy price rises, and while we have more to do, this new study shows our policies are putting a cushion between global prices and the bills we all pay."

Caroline Flint, shadow energy and climate change secretary, said: "The government's underhand attempt to mask the real impact of its policies on families' energy bills is shameful... Instead of cooking the books to trick people into thinking their energy bills will be lower, ministers should get behind Labour's plans to overhaul the energy market and deliver fair prices for the public."

'Less positive'

The report also found that businesses that are medium-sized users of energy currently face energy costs that are on average 21% higher as a result of energy and climate change policies, with this figure rising to 22% by 2020.

Large energy-intensive users currently face energy costs that are on average between one and 14% higher as a result of policies, with this rising to between six and 36% by 2020.

The estimates did not include measures the government was currently considering to reduce the impact of low carbon policies on the costs of electricity for energy intensive industries, including a ?250m package of compensation for industry to 2014/2015.

Mr Davey said: "The picture for business is less positive, which is why our new proposals to exempt and compensate the most energy intensive industries from certain policy impacts is crucial. Nothing would be gained from forcing industry, jobs and emissions abroad."

Steve Radley, policy director at EEF, the manufacturers' organisation, said: "Measures to shield the most energy-intensive industries from a portion of the costs will make a difference but, unless we get a grip on spiralling policy costs, steeply rising electricity prices for the rest of the sector risk making the UK an increasingly unattractive location for industrial investment and undermining efforts to rebalance the economy.

"The first step is scrapping costly policies with questionable environmental impact, such as the carbon price floor and the CRC Energy Efficiency Scheme, as soon as public finances allow."

Arkansas governor vetoes voter ID bill

By Suzi Parker

LITTLE ROCK, Ark (Reuters) - Arkansas Governor Mike Beebe on Monday vetoed a bill proposing citizens show photo identification before casting a ballot, citing risks it could disenfranchise voters, the governor's office said.

Supporters of the proposal, who say it would eliminate the possibility of fraud, plan to override the veto by Beebe, a Democrat. That would require a simple majority in a vote in each chamber of the Republican-dominated state legislature.

Should the bill become law, Arkansas would join the nearly three dozen U.S. states that have similar voter ID measures, according to the National Conference of State Legislatures.

In his veto letter, Beebe said he "believes that the bill will unnecessarily cost taxpayers money, grow bureaucracy and risk disenfranchisement of voters."

"I cannot approve such an unnecessary measure that would negatively impact one of our most precious rights as citizens," Beebe added.

The bill previously passed 22-12 in the state Senate and 51-44 in the House.

Legal challenges to voter ID laws are pending in several U.S. states and are expected in Arkansas if it adopts the measure.

Under current Arkansas law, poll workers can request identifying documents, but voters are not required to show them.

Under the proposed law, photo ID cards would be made by county clerks at no cost for registered voters who do not have other valid forms of identification. The state Bureau of Legislative Research has reported it would cost the state an additional $300,000.

Voters without an ID could still cast a provisional ballot, which would be counted if the voter returned with photo identification.

Google selects Glass Explorers, will send invites to winners over the next few days

What would you do if you had Glass? Google asked you to share your plans last month, offering up 8,000 coveted reservations in the search giant's "Explorers" program. Now, the company has finally selected the winners, and plans to send out order invitations "over the next few days." Sadly, invite recipients will still need to hand over $1,500 (plus tax) for their very own set, and the program is currently limited to folks in the US, but this was still the best opportunity to get an early look at Glass, making it a very appealing program, despite the cost. Google received many creative applications, including a proposal from JetBlue, but only individual users will have an opportunity to make a purchase this time around -- the company says that it's "working on connecting with businesses in other ways." Congratulations to the lucky winners -- feel free to send us a tip when word finally hits your Google+ or Twitter inbox.

The answer has remained constant for centuries: Your grown?children.

Maybe not in their home, but in their hearts, minds and actions until the day you die. You took care of them as babies, toddlers and teens. It?s payback?time.

The baby boomer generation, those born between 1946 and 1964, might be the first generation unable to count on their grown children as caregivers, if they even had?children.

It?s a new world, future oldsters. Get?ready.

Who will take care of us when we are old and?frail?

The answer has remained constant for centuries: Your grown?children.

Maybe not in their home, but in their hearts, minds and actions until the day you die. You took care of them as babies, toddlers and teens. It?s payback?time.

The baby boomer generation, those born between 1946 and 1964, might be the first generation unable to count on their grown children as caregivers, if they even had?children.

It?s a new world, future oldsters. Get?ready.

The Past: Big families, great?expectations

Becky Tiller grew up around all four grandparents near Nampa, Idaho. The grandparents often baby-sat Tiller and her siblings. When these family elders grew dependent, Tiller?s parents returned the?favor.

?Three of my four grandparents ended up with dementia, and the family was there to help,? said Tiller, owner of Tiller Care Strategies in Spokane, an adult and geriatric care management?firm.

From 1991 to 2001, Gail Goeller of Spokane oversaw the care of five family elders ? her parents, her in-laws and an aunt. Goeller?s parents had role-modeled devotion to aging elders. When Goeller was a child, her widowed grandfather lived?nearby.

?Every morning, my mom would see his hand come through the gate for breakfast. She knew it was part of the package,? remembered Goeller, author of ?Coming of Age with Aging?Parents.?

Family elder-care expectations were reinforced by religious teachings. Honor thy mother and father, and if you don?t, suffer some Catholic, Jewish, Protestant, Muslim, Hindu, fill-in-the-blank-religion?guilt.

If one grown child was immune to this guilt, another could step in, because boomers? families of origin were bigger than families?now.

In 1960, the average fertility rate for women in the United States was about four children. By the 1970s, when many of the older boomers started having families, the fertility rate dropped well below two children, where it remains, according to National Health Statistics?Reports.

Peggy Mangiaracina, 61, was a middle child in a family of nine?kids.

Between 1996 and 2009, her parents faced serious health challenges. Mangiaracina?s mother underwent three hip surgeries. Her father had a stroke and eventually, Alzheimer?s set?in.

Mangiaracina, a nurse who was vice president/executive director of Sacred Heart Children?s Hospital until her retirement in 2011, took family leave several times to fly back to central Minnesota to provide nursing care for her parents. There?s an old saying that one mother can raise nine children, but it takes nine children to care for one aging mother. In Mangiaracina?s family of origin, everyone pitched?in.

?I had only about three letters from my father in my whole lifetime, but my dad wrote me a letter after Mom?s first hip surgery,? Mangiaracina said. ?He wrote, ?I can?t tell you what it meant to know you would drop everything in your life and come home and take care of?Mom.???

The present: Changing?times

Mangiaracina and her husband, Mark, have two grown children. Neither lives in?Spokane.

Goeller has two children. Both live in?Spokane.

Tiller, who never married, has no?children.

Baby boomers did not replicate the larger families they grew up in, and about one third of grown children no longer live in close proximity to their aging?parents.

Those grown boomer daughters who many expected would step in to care for parents in older age? They are busier than?ever.

Since the mid-1980s the number of women in the workforce has grown by 44 percent, according to a 2010 congressional report, and 70 percent of those working women are?mothers.

?With the impact of the women?s movement, we could have it all: career, children, volunteering, staying fit, inviting dads to do more child care,? Goeller said. ?Our daily tempo sped up, compared to the generation?before.?

Despite the changing times, families still provide a good deal of care for aging parents. AARP reports that 42.1 million family members ? men and women ? now provide care to frail, elderly family?members.

Aging baby boomers, however, might be the last generation prone to feeling guilty if they don?t come through for their parents. Young people are not as involved with the religious institutions that reinforced honor-thy-mother-and-father?guilt.

A 2012 Pew Forum on Religion and Public Life report found that, among adults younger than 30, one-third were not affiliated with any?religion.

Guilt, so far, is alive and?well.

?I hear a lot of ?shoulds? and ?this is my responsibility,??? Tiller said. ?I do a lot of counseling with the adult children about not assuming responsibilities they can?t fulfill. A lot of them are not geared to be caregivers. I tell them they would have a better role overseeing the care, not giving the?care.?

The future: Communes, immigrants,?robots

Some aging baby boomers won?t have grown children to depend?on.

In the decades of peak childbearing years for baby boomers, the percentage of childless couples increased significantly, from 2.4 percent in 1982 to 6.6 percent by 1995, according to the National Center of Health?Statistics.

If older boomers can?t depend on grown children, where will they?turn?

?They?ll establish nontraditional relationships,? Tiller predicted. ?You?ll see the ?Golden Girls? motif. People will live?communally.?

New immigrants to the United States might be key?caregivers.

?Right now we have a huge population of Russian immigrants opening adult family homes,? she said. ?There are more people coming from the old world, and they honor their elders. They are not afraid of changing incontinence?briefs.?

Technology might provide care, too. So-called ?granny cams? already allow children to keep a virtual eye on elderly parents, and a 2012 Journal of Aging Research report concludes that elder-care robots ? still in the testing stages ? will enable people to remain living at?home.

Neither Goeller nor Mangiaracina expect ? or even desire ? their children to do hands-on care for them, but they are confident their children will walk with them in their old-age?journeys.

Both women believe the younger generation will provide elder care in more creative and holistic?ways.

?Part of what we gave our children was the idea that even if you didn?t come from a family of nine, you are part of a larger community,? Mangiaracina said. ?When my kids went to Gonzaga Prep, they did food drives and other sorts of things. Maybe some of their generation will say, ?I could go over to that lady?s house. I could do Meals on Wheels.? They feel an obligation to a wider?community.?

COLUMBIA, Mo. Breakfast might be the most important meal of the day, but up to 60 percent of American young people consistently skip it. Now, Heather Leidy, an assistant professor in the Department of Nutrition and Exercise Physiology, says eating a breakfast rich in protein significantly improves appetite control and reduces unhealthy snacking on high-fat or high-sugar foods in the evening, which could help improve the diets of more than 25 million overweight or obese young adults in the U.S.

Leidy is the first to examine the impact of breakfast consumption on daily appetite and evening snacking in young people who habitually skip breakfast. In her study, 20 overweight or obese adolescent females ages 18-20 either skipped breakfast, consumed a high-protein breakfast consisting of eggs and lean beef, or ate a normal-protein breakfast of ready-to-eat cereal. Every breakfast consisted of 350 calories and was matched for dietary fat, fiber, sugar and energy density. The high-protein breakfast contained 35 grams of protein. Participants completed questionnaires and provided blood samples throughout the day. Prior to dinner, a brain scan using functional magnetic resonance imaging (fMRI) was performed to track brain signals that control food motivation and reward-driven eating behavior.

The consumption of the high-protein breakfast led to increased fullness or "satiety" along with reductions in brain activity that is responsible for controlling food cravings. The high-protein breakfast also reduced evening snacking on high-fat and high-sugar foods compared to when breakfast was skipped or when a normal protein, ready-to-eat cereal breakfast was consumed, Leidy said.

"Eating a protein-rich breakfast impacts the drive to eat later in the day, when people are more likely to consume high-fat or high-sugar snacks," Leidy said. "These data suggest that eating a protein-rich breakfast is one potential strategy to prevent overeating and improve diet quality by replacing unhealthy snacks with high quality breakfast foods."

People who normally skip breakfast might be skeptical about consuming food in the morning, but Leidy says it only takes about three days for the body to adjust to eating early in the day. Study participants ate egg and beef-based foods such as burritos or egg-based waffles with applesauce and a beef sausage patty as part of a high-protein breakfast; Leidy also suggests eating plain Greek yogurt, cottage cheese or ground pork loin as alternatives to reach the 35 grams of protein.

Future research will examine whether regularly consuming high-protein breakfasts improves body weight management in young people.

Counting white blood cells at home

Mar. 26, 2013 ? White blood cells, or leukocytes, are the immune system's warriors. So when an infection or disease attacks the body, the system typically responds by sending more white blood cells into the fray. This means that checking the number of these cells is a relatively easy way to detect and monitor such conditions.

Currently, most white blood cell counts are performed with large-scale equipment in central clinical laboratories. If a physician collects blood samples from a patient in the office -- usually requiring a full vial of blood for each test -- it can take days to get the results. But now engineers at the California Institute of Technology (Caltech), working with a collaborator from the Jerusalem-based company LeukoDx, have developed a portable device to count white blood cells that needs less than a pinprick's worth of blood and takes just minutes to run.

"The white blood cell counts from our new system closely match the results from tests conducted in hospitals and other central clinical settings," says Yu-Chong Tai, professor of electrical engineering and mechanical engineering at Caltech and the project's principal investigator. "This could make point-of-care testing possible for the first time."

Portable white blood cell counters could improve outpatient monitoring of patients with chronic conditions such as leukemia or other cancers. The counters could be used in combination with telemedicine to bring medical care to remote areas. The devices could even enable astronauts to evaluate their long-term exposure to radiation while they are still in space. The researchers describe the work in the April 7 issue of the journal Lab on a Chip.

There are five subtypes of white blood cells, and each serves a different function, which means it's useful to know the count for all of them. In general, lymphocytes use antibodies to attack certain viruses and bacteria; neutrophils are especially good at combating bacteria; eosinophils target parasites and certain infections; monocytes respond to inflammation and replenish white blood cells within bodily tissue; and basophils, the rarest of the subtypes, attack certain parasites.

"If we can give you a quick white blood cell count right in the doctor's office," says Wendian Shi, a graduate student in Tai's lab and lead author of the new paper, "you can know right away if you're dealing with a viral infection or a bacterial infection, and the doctor can prescribe the right medication."

The prototype device is able to count all five subtypes of white blood cells within a sample. It provides an accurate differential of the four major subtypes -- lymphocytes, monocytes, eosinophils, and neutrophils. In addition, it could be used to flag an abnormally high level of the fifth subtype, basophils, which are normally too rare (representing less than one percent of all white blood cells) for accurate detection in clinical tests.

The entire new system fits in a small suitcase (12" x 9" x 5") and could easily be made into a handheld device, the engineers say.

A major development reported in the new paper is the creation of a detection assay that uses three dyes to stain white blood cells so that they emit light, or fluoresce, brightly in response to laser light. Blood samples are treated with this dye assay before measurement in the new device. The first dye binds strongly to the DNA found in the nucleus of white blood cells, making it simple to distinguish between white blood cells and the red blood cells that surround and outnumber them. The other two dyes help differentiate between the subtypes.

The heart of the new device is a 50-micrometer-long transparent channel made out of a silicone material with a cross section of only 32 micrometers by 28 micrometers -- small enough to ensure that only one white blood cell at a time can flow through the detection region. The stained blood sample flows through this microfluidic channel to the detection region, where it is illuminated with a laser, causing it to fluoresce. The resulting emission of the sample is then split by a mirror into two beams, representing the green and red fluorescence.

Thanks to the dye assay, the white blood cell subtypes emit characteristic amounts of red and green light. Therefore, by determining the intensity of the emissions for each detected cell, the device can generate highly accurate differential white blood cell counts.

Shi says his ultimate goal is to develop a portable device that can help patients living with chronic diseases at home. "For these patients, who struggle to find a balance between their treatment and their normal quality of life, we would like to offer a device that will help them monitor their conditions at home," he says. "It would be nice to limit the number of trips they need to make to the hospital for testing."
