SEFFNER, Fla. (AP) ? Authorities hope to get a better look at a sinkhole that swallowed a man in his Florida home once demolition crews knock down the remaining walls of the house Monday and begin clearing away the debris.

Crews on Sunday razed more than half the home, managing to salvage some keepsakes for family members who lived there.

The opening of the sinkhole has been covered by the home, but once emergency officials and engineers can see inside it more clearly, they could begin planning how to deal with it. They also need to decide what will happen to the two homes on either side of the now-demolished house. Experts say the sinkhole has "compromised" those homes, but it's unclear whether steps can be taken to save them.

Jeremy Bush, 35, tried to save his brother, Jeff, when the earth opened up and swallowed him Thursday night.

On Sunday morning, Bush and relatives prayed with a pastor as the home ? where he lived with his girlfriend, Rachel Wicker; their daughter, Hannah, 2; and others ? was demolished and waited for firefighters to salvage anything possible from inside. The home was owned by Leland Wicker, Rachel's grandfather, since the 1970s.

The operator of the heavy equipment worked gingerly, first taking off a front wall. Family belongings were scooped onto the lawn gently in hopes of salvaging parts of the family's 40-year history in the home.

As of Sunday afternoon ? when demolition had stopped for the day and only a few walls remained ? a Bible, family photos, a jewelry box and a pink teddy bear for Hannah were among the items saved. Firefighters also were able to pick out the purse of one of the women in the home.

Cheers went up from family, friends and neighbors each time something valuable was salvaged.

Wanda Carter, the daughter of Leland Wicker, cradled the large family Bible in her arms. She said her mother and father had stored baptism certificates, cards and photos between the pages of that Bible over the years.

"It means that God is still in control, and He knew we needed this for closure," she said, crying.

Carter said she spent from age 11 to 20 in the home, and she had to close her eyes as the home was knocked down.

"Thank you for all of the memories and life it gave us," she said.

The Rev. John Martin Bell of Shoals Baptist Church said he had been with the family all morning. "We just prayed with them," he said. He added that all five who lived in the house ? Bush, Wicker, Hannah and two others ages 50 and 45 ? were in need of support and prayers from the community.

Several generations of family members lived in the home at the time of the ground collapse, including Jeff Bush, the man now presumed dead.

Jeremy Bush tried to save his brother by jumping into the sinking dirt hole. He had to be pulled out of the still-shifting hole by a Hillsborough County Sheriff's deputy, who was visibly shaken when talking about the incident more than a day later.

"I've never seen anything move so fast and do so much destruction," Deputy Douglas Duvall said.

The search for Jeff Bush, 37, was called off Saturday. He was in his bedroom Thursday night in Seffner ? a suburb of 8,000 people 15 miles east of downtown Tampa ? when the ground opened and took him and everything else in his room. Five others in the house at the time escape unharmed as the earth crumbled.

The Hillsborough County Sheriff's Office is conducting the investigation. Detective Larry McKinnon said the sheriff's office and the county medical examiner cannot declare Bush dead if his body is still missing. Under Florida law, Bush's family must petition a court to declare him deceased.

"Based on the circumstances, he's presumed dead; however the official death certificate can only be issued by a judge and the family has to petition the court," McKinnon said.

The area around Seffner is known for sinkholes due to the geography of the terrain, but they are rarely deadly. No one ? from longtime public safety officials to geologists ? could remember an incident where a person was sucked into the earth without warning.

Kerry says US releasing millions in aid to Egypt

CAIRO (AP) ? U.S. Secretary of State John Kerry on Sunday rewarded Egypt for President Mohammed Morsi's pledges of political and economic reforms by releasing $250 million in American aid to support the country's "future as a democracy."

Yet Kerry also served notice that the Obama administration will kept close watch on how Morsi, who came to power in June as Egypt's first freely elected president, honors his commitment.

"The path to that future has clearly been difficult and much work remains," Kerry said in a statement after wrapping up two days of meetings in Egypt, a deeply divided country in the wake of the revolution that ousted longtime President Hosni Mubarak.

Egypt is trying to meet conditions to close on a $4.8 billion loan package from the International Monetary Fund. An agreement would unlock more of the $1 billion in U.S. assistance promised by President Barack Obama last year and set to begin flowing with Kerry's announcement.

"The United States can and wants to do more," Kerry said. "Reaching an agreement with the IMF will require further effort on the part of the Egyptian government and broad support for reform by all Egyptians. When Egypt takes the difficult steps to strengthen its economy and build political unity and justice, we will work with our Congress at home on additional support."

Kerry cited Egypt's "extreme needs" and Morsi's "assurances that he plans to complete the IMF process" when he told the president that the U.S. would provide $190 million of a long-term $450 million pledge "in a good-faith effort to spur reform and help the Egyptian people at this difficult time."

Separately, the top U.S. diplomat announced $60 million for a new fund for "direct support of key engines of democratic change," including Egypt's entrepreneurs and its young people. Kerry held out the prospect of U.S. assistance to this fund climbing to $300 million over time.

Recapping his meetings with political figures, business leaders and representatives of outside groups, Kerry said he heard of their "deep concern about the political course of their country, the need to strengthen human rights protections, justice and the rule of law, and their fundamental anxiety about the economic future of Egypt."

Those issues came up in "a very candid and constructive manner" during Kerry's talks with Morsi.

"It is clear that more hard work and compromise will be required to restore unity, political stability and economic health to Egypt," Kerry said.

Syria and Iran also came up, according to officials.

With parliamentary elections in April approaching and liberal and secular opponents of Morsi's Muslim Brotherhood saying they will boycott, Kerry called the vote "a particularly critical step" in Egypt's democratic transition.

Violent clashes between protesters and security forces have created an environment of insecurity, complicating Egyptian efforts to secure vital international aid.

Officials in the Egyptian presidency said Kerry stressed the need for consensus with the opposition in order to restore confidence in Egypt that it can ride out the crisis. Morsi was reported to have expressed the importance of Egypt's relationship with United States, which is based on "mutual respect," and focused on the importance of the democratic process in building a strong and stable nation.

Kerry made clear that in all his meetings, he conveyed the message that Egyptians who rose up and overthrew Mubarak "did not risk their lives to see that opportunity for a brighter future squandered."

He also told the country's bickering politicians that they must overcome differences to get Egypt's faltering economy back on track and maintain its leadership role in the volatile Middle East.

The U.S. is deeply concerned that continued instability in Egypt will have broader consequences in a region already rocked by unrest.

U.S. officials said Kerry had planned to stress the importance of upholding Egypt's peace agreement with Israel, cracking down on weapons smuggling to extremists in the Gaza Strip and policing the increasingly lawless Sinai Peninsula while continuing to play a positive role in Syria's civil war.

The impact of his message of unity to the opposition coalition seemingly was blunted when only six of the 11 guests invited by the U.S. Embassy turned up for the Saturday session and three of those six said they still intended to boycott the April parliamentary election, according to participants.

Kerry said that the U.S. would not pick sides in Egypt, and he appealed to all sides to come together around human rights, freedom and speech and religious tolerance.

In an apparent nod to the current stalemate in Washington over the U.S. federal budget, Kerry acknowledged after meeting Foreign Minister Kamel Amr that compromise is difficult yet imperative.

"I say with both humility and with a great deal of respect that getting there requires a genuine give-and-take among Egypt's political leaders and civil society groups just as we are continuing to struggle with that in our own country," he said. 'There must be a willingness on all sides to make meaningful compromises on the issues that matter most to all of the Egyptian people."

The opposition accuses Morsi and the Brotherhood of following in the footsteps of Mubarak, failing to carry out reforms and trying to install a more religiously conservative system.

Morsi's administration and the Brotherhood say their foes, who have trailed significantly behind Islamists in all elections since the uprising against Mubarak, are running away from the challenge of the ballot box and are trying to overturn democratic gains.

From Egypt, Kerry headed to Saudi Arabia on Sunday, with later stops in the United Arab Emirates and Qatar, where his focus is expected to be the crisis in Syria

Kerry is set to return to Washington on Wednesday.

Improved synchronicity: Preventive care for the power grid

Mar. 1, 2013 ? President Obama in this year's State of the Union address talked about the future of energy and mentioned "self-healing power grids" -- a grid that is able to keep itself stable during normal conditions and also to self-recover in the event of a disturbance caused, for example, by severe weather.

But as the national power-grid network becomes larger and more complex achieving reliability across the network is increasingly difficult. Now Northwestern University scientists have identified conditions and properties that power companies can consider using to keep power generators in the desired synchronized state and help make a self-healing power grid a reality.

The Northwestern team's design for a better power grid could help reduce both the frequency of blackouts and the cost of electricity as well as offer an improved plan for handling the intermittent power sources of renewable energy, such as solar and wind power, which can destabilize the network.

"We will be looking at a completely different power grid in the future," said Adilson E. Motter, who led the research. "The use of renewable energy is growing. More people will be driving electric cars, and the power grid will be delivering this energy, not gas stations. We need a power grid that is more capable and more reliable. This requires a better understanding of the current power grid as well as new ways to stabilize it."

Motter is the Harold H. and Virginia Anderson Professor of Physics and Astronomy at Northwestern's Weinberg College of Arts and Sciences.

The crux of the challenge is that for the U.S. power grid to function the power generators in each of its three interconnections (Eastern, Western and Texas) must be synchronized, all operating at the frequency of 60 hertz. Out-of-synch power generators can lead to blackouts that affect millions of people and cost billions of dollars -- losses similar to those of the Northeast blackout of 2003.

Having a network that can synchronize spontaneously and recover from failures in real time -- in other words, a self-healing power grid -- could prevent such blackouts. To help achieve this, power companies could apply the Northwestern guidelines as they add power generators to the network or tweak existing generators.

A paper describing the researchers' mathematical model, titled "Spontaneous synchrony in power-grid networks," is published in the March 2013 issue of the journal Nature Physics.

When a problem develops in the power-grid network, control devices are used to return power generators to a synchronized state. Motter likens this to using medicine to treat someone who is ill. He and his colleagues are suggesting conditions to keep synchronicity in good shape so interventions are kept to a minimum.

"Our approach is preventive care -- preventing failures instead of mitigating them," said Motter, an author of the paper and an executive committee member of the Northwestern Institute on Complex Systems (NICO). "The guidelines we offer could be very useful as the power grid expands."

The researchers derived a condition under which the desired synchronous state of a power grid is stable. They then used this condition to identify tunable parameters of the power generators that result in spontaneous synchronization. This synchronization can be autonomous, not guided by control devices.

"The blackout at this year's Super Bowl was caused by a device that was installed specifically to prevent blackouts," said Takashi Nishikawa, an author of the paper and a research associate professor of physics and astronomy at Northwestern. "A large fraction of blackouts have human and equipment errors among the causes.

"Reduced dependence on conventional control devices can improve the reliability of the grid," he said. "Our analysis also suggests ways to design control strategies that potentially can improve the existing ones."

Power generators are very different from each other; some are large and others small. Motter and his colleagues identified a "body mass index" for power generators, which they suggest should be kept approximately the same (making, in essence, all generators look the same to the network) in order to strengthen spontaneous synchronicity in the system. If the body mass indices change, they should be changed in a coordinated way.

The researchers demonstrated their model using real power grids of hundreds of power generators, similar to the size of the Texas portion of the U.S. power grid.

WASHINGTON (AP) ? A new State Department report is the latest evidence that the long-delayed Keystone XL oil pipeline from Canada should be approved, supporters say.

The draft report, issued Friday, finds there would be no significant environmental impact to most resources along the proposed route from western Canada to refineries in Texas. The report also said other options to get the oil from Canada to Gulf Coast refineries are worse for climate change.

The new report "again makes clear there is no reason for this critical pipeline to be blocked one more day," said House Speaker John Boehner, R-Ohio. After four years of what he called "needless delays," Boehner said it is time for President Barack Obama "to stand up for middle-class jobs and energy security and approve the Keystone pipeline."

Environmentalists see the State Department report in a vastly different light.

They say it was inadequate and failed to account for climate risks posed by the pipeline. The report also is based on a false premise, opponents say ? namely, that tar sands in western Canada will be developed for oil production regardless of whether the Keystone XL pipeline is approved.

"Americans are already suffering from the consequences of global warming, from more powerful storms like Hurricane Sandy to drought conditions currently devastating the Midwest and Southwest," said Daniel Gatti of the group Environment America. Production of oil from Canadian tar sands could add as much as 240 billion metric tons of global warming pollution to the atmosphere, Gatti said, a potential catastrophe that would hasten the arrival of the worst effects of global warming.

Gatti and other opponents said development of the vast tar sands is far from certain, despite assurances by the project's supporters.

"Tar sands can be stopped, and we are stopping it," Gatti said, citing a rally in Washington last month attended by an estimated 35,000 people. Project opponents also have blocked construction in Texas and Oklahoma and have been arrested outside the White House gate.

The pipeline plan has become a flashpoint in the U.S. debate over climate change. Republicans and business and labor groups have urged the Obama administration to approve the project as a source of jobs and a step toward North American energy independence. Environmental groups have been pressuring the president to reject the pipeline, saying it would carry "dirty oil" that contributes to global warming. They also worry about a spill.

The State Department review stopped short of recommending approval of the project, but it gave the Obama administration political cover if it chooses to endorse the pipeline in the face of opposition from many Democrats and environmental groups. State Department approval of the 1,700-mile pipeline is needed because it crosses a U.S. border.

The lengthy report says Canadian tar sands are likely to be developed, regardless of whether the U.S. approves the Keystone XL pipeline, which would carry oil through Montana, South Dakota, Kansas, Nebraska and Oklahoma.

The report acknowledges that development of tar sands in Alberta would create greenhouse gases but makes clear that other methods of transporting the oil ? including rail, trucks and barges ? also pose a risk to the environment.

The State Department analysis for the first time evaluated two options using rail: shipping the oil on trains to existing pipelines or to oil tankers. The report shows that those other methods would release more greenhouse gases that contribute to global warming than the pipeline. The Keystone XL pipeline, according to the report, would release annually the same amount of global warming pollution as 626,000 passenger cars.

A scenario that would move the oil on trains to mostly existing pipelines would release 8 percent more greenhouse gases such as carbon dioxide than Keystone XL. That scenario would not require State Department approval because any new pipelines would not cross the U.S border.

Another alternative that relies mostly on rail to move the oil to the Canadian west coast, where it would be loaded onto oil tankers to the U.S. Gulf Coast, would result in 17 percent more greenhouse gas emissions, the report said.

In both alternatives, the oil would be shipped in rail cars as bitumen, a thick, tar-like substance, rather than as a liquid.

The State Department was required to conduct a new environmental analysis after the pipeline's operator, Calgary-based TransCanada, changed the project's route though Nebraska. The Obama administration blocked the project last year because of concerns that the original route would have jeopardized environmentally sensitive land in the Sand Hills region.

The administration later approved a southern section of the pipeline, from Cushing, Okla., to the Texas coast, as part of what Obama has called an "all of the above" energy policy that embraces a wide range of sources, from oil and gas to renewables such as wind and solar.

The draft report issued Friday begins a 45-day comment period, after which the State Department will issue a final environmental report before Secretary of State John Kerry makes a recommendation about whether the pipeline is in the national interest.

Kerry has promised a "fair and transparent" review of the plan and said he hopes to decide on the project in the "near term." Most observers do not expect a decision until summer at the earliest.

Canadian Natural Resource Minister Joe Oliver said Friday that Canada will respect the U.S. review process and noted the importance of the pipeline to the Canadian economy.

Obama's initial rejection of the pipeline last year went over badly in Canada, which relies on the United States for 97 percent of its energy exports.

Problems with identifying meat? The answer is to check the barcode

Mar. 1, 2013 ? Want to know what you are eating? DNA barcodes can be used to identify even very closely related species, finds an article published in BioMed Central's open access journal Investigative Genetics. Results from the study show that the labelling of game meat in South Africa is very poor with different species being substituted almost 80% of the time.

In South Africa game meat biltong (air dried strips) is big business with over 10,000 wildlife farms and is supplemented by private hunting. This meat is considered to be 'healthier' than beef because it is lower in fat and cholesterol and perceived to be lower in additives.

Using mitochondrial COI DNA barcoding and cytb sequencing, researchers analysed samples of game meat from supermarkets, wholesalers and other outlets and compared them to known samples and library sequences. From 146 samples over 100 were mislabelled.

All the beef samples were correct, but for the most badly labelled case 92% of kudu was a different species. Only 24% of springbok and ostrich biltong was actually springbok or ostrich. The rest was horse, impala, hartebeest, wildebeest, waterbok, eland, gemsbok, duiker, giraffe, kangaroo, lamb, pork or beef. Worryingly one sample labelled zebra was actually mountain zebra, a 'red listed' species threatened with extinction.

Maria Eugenia D'Amato from the University of the Western Cape commented, "The delivery of unidentifiable animal carcasses to market and the general lack of regulations increases the chances of species mislabelling and fraud. This has implications for species safety but also has cultural and religious implications. This technique is also able to provide new information about the identity of animals and meant that we found several animals whose DNA had been misidentified in the scientific libraries."
