PORT SAID, Egypt (AP) ? Parts of a government complex were set on fire as protesters throwing stones and firebombs clashed with police firing tear gas and birdshot Monday in a new day of clashes that have caught the military in the middle of fighting in the restive Egyptian city of Port Said.
The renewed clashes came hours after thousands of city residents rallied in a funeral procession for civilians killed during street battles with police a day earlier in which three policemen and three civilians were killed.
The two days of clashes have dragged in the military to a dramatic extent. Troops trying to break up fighting have been overwhelmed by police tear gas, one army colonel was wounded by live fire, and at some points troops have opened fire over the heads of police. The scenes have underlined a scenario that many in Egypt view with a mix of concern and relief ? that the military may move back into politics, prompted by mushrooming protests, a breakdown in law and order and mounting challenges to the Islamist president.
On Monday, the military deployed soldiers and cars to escort the funeral procession. "We want retribution," the marchers chanted. "It is now war between us and you, Interior Ministry." Protesters in the procession, carrying the coffins of the dead to the cemetery, waved the black-white-and-green flags of Port Said that have become a symbol of the city's revolt against the government.
Violence erupted when protesters on the way back from the funeral hurled rocks at the police headquarters, which lies in a government complex. Police responded with volleys of tear gas.
The military stood by as protesters and police exchanged projectiles, witnesses said. At one point, the military fired in the air to stop the violence. Flames were visible from the provincial government's headquarters and a nearby tax authority office, adjacent to the police building. Firefighters were unable to reach the blaze.
Amira el-Alfi, a 33-year-old resident of Port Said who watched as the building caught fire, said the scene was confusing.
"The government building is on fire. We don't know who is aiming at who. But young people end up dying," she said as she coughed from tear gas.
Medical officials said at least eight people were injured by birdshot.
The wrath among residents of Port Said is aimed at the police force, which many accuse of using excessive force that led to the killing of more than 40 civilians during protests in January. The city has seen the heaviest protests in a wave of unrest around the country in recent months. In at least two separate incidents in Cairo on Monday, protesters torched two police vehicles, setting them on fire and driving the policemen in the cars running in the middle of traffic on major thoroughfares.
Port Said, on the Mediterranean coast at the mouth of the Suez Canal, has been in turmoil since late January, when a Cairo court issued death sentences against 21 people, most residents of the city, for involvement in Egypt's deadliest soccer riot in February 2012. The verdicts sparked angry protests in the city, which turned into deadly clashes with police, leaving more than 40 dead, including two policemen.
Residents have been outraged by what they call excessive force by the police and by the central government's response ? Islamist President Mohammed Morsi called the protesters "thugs" and has generally backed the security forces. The police said most of the protester deaths came during an attempt to storm a prison.
Tensions have risen further ahead of a court hearing planned for Saturday that is expected to confirm the death sentences to issue new verdicts for police officers and other Port Said defendants also charged in connection with the soccer tragedy.
For nearly three weeks, the city has seen protests, strikes and work stoppages, including the blocking of a major port.
The fighting Sunday saw the most dramatic instance of the military being pulled into the middle of Egypt's escalating tensions.
Witnesses described a tense scene between the police and the military during the clashes. The fighting began when thousands of protesters marched on the police headquarters after word emerged that 39 defendants in the soccer violence case had been transferred to prisons outside the city. The move apparently aimed to ensure calm ahead of Saturday's hearing in the case.
The protesters Sunday lobbed rocks and firebombs at the police building. The police, heavily deployed around their building, moved out to try to push back the protesters.
Army officers tried but failed to negotiate an end to the fighting, then pulled back from between the two sides. Then the troops began getting hit. An army colonel, Sherif el-Arayishi, was shot in the right leg by live ammunition, military spokesman Ahmed Mohammed Ali said. Also, soldiers were overwhelmed by the tear gas that police were firing at the protesters. In one case, captured on video, a tear gas canister fell inside a military armored vehicle, and the choking soldiers stumbled out, helped by protesters who carried them to an ambulance.
Then the military moved back in, deploying their vehicles back in the crowds between the protesters and police. They fired in the air in the direction of the police, prompting cheers from the protesters, witnesses said. People chanted at one point: "The people and army are one hand."
"We had doubted the military, thought it was only there to protect installations. What they did yesterday restored our confidence," said one protester who had witnessed the scene, 25-year-old Mohammed Atef. "We felt they are feeling the injustices against us; that they decided to protect us too."
On Monday, both the military and the Interior Ministry, which is in charge of the police, sought to dispel any sign of friction between their forces. The Interior Ministry issued a statement saying "unknown elements" fired arbitrarily at the police and military with the aim of sowing sedition and causing escalation.
In a statement late Sunday, the military denied it fired at police. Ali, the military spokesman, said the armed forces were protecting installations and separating protesters and the police. On Monday, Ali said that the fact that people on both sides were injured indicates that unknown elements were behind the gunfire.

SEFFNER, Fla. (AP) ? Crews planned to begin demolishing a Florida home Sunday that is perched over a huge sinkhole, deeming it too dangerous to keep searching for the man swallowed into the earth from his bedroom.
The search for Jeff Bush, 37, was called off Saturday. The 20-foot-wide opening of the sinkhole is almost completely covered by the house and rescuers feared it would collapse on them. Two neighboring homes were evacuated as a precaution.
Hillsborough County Administrator Mike Merrill said heavy equipment would be brought in to begin razing the home Sunday morning.
"At this point it's really not possible to recover the body," Merrill said, later adding "we're dealing with a very unusual sinkhole."
Jessica Damico, spokeswoman for Hillsborough County Fire Rescue, said the demolition equipment would be placed on what they believe is solid ground and reach onto the property to pull apart the house. The crew will try pulling part of the house away from the sinkhole intact so some of the residents' keepsakes can be retrieved.
Bush 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 escape unharmed as the earth crumbled.
On Saturday, the normally quiet neighborhood of concrete block homes painted in Florida pastels was jammed with cars. Engineers, reporters, and curious onlookers came to the scene.
At the home next door to the Bushes, a family cried and organized boxes. Testing determined that their house and another had been compromised by the sinkhole. The families were allowed to go inside for about a half-hour to gather belongings.
Sisters Soliris and Elbairis Gonzalez, who live on the same street as the Bushes, said neighbors were worried for their safety.
"I've had nightmares," Soliris Gonzalez, 31, said. "In my dreams, I keep checking for cracks in the house."
They said the family has discussed where to go if forced to evacuate, and they've taken their important documents to a storage unit.
"The rest of it, this is material stuff, as long as our family is fine," Soliris Gonzalez said.
"You never know underneath the ground what's happening," added Elbairis Gonzalez, 30.
Experts say thousands of sinkholes form yearly in Florida because of the state's unique geography, though most are small and deaths rarely occur.
"There's hardly a place in Florida that's immune to sinkholes," said Sandy Nettles, who owns a geology consulting company in the Tampa area. "There's no way of ever predicting where a sinkhole is going to occur."
Most sinkholes are small, like one found Saturday morning in Largo, 35 miles away from Seffner. The Largo sinkhole, about 10 feet long and several feet wide, is in a mall parking lot.
The state sits on limestone, a porous rock that easily dissolves in water, with a layer of clay on top. The clay is thicker in some locations ? including the area where Bush became a victim ? making them even more prone to sinkholes.
Jonathan Arthur, the state geologist and director of the Florida Geological Survey, said other states sit atop limestone in a similar way, but Florida has added factors such as extreme weather, development, aquifer pumping and construction.
"The conditions under which a sinkhole will form can be very rapid, or they can form slowly over time," he said.
But it remained unclear Saturday what, if anything, had caused the Seffner sinkhole.
"The condition that caused that sinkhole could have started a million years ago," Nettles said.
Jeremy Bush, who tried to rescue his brother, lay flowers near the house Saturday morning and wept.
He said someone came to his home a couple of months ago to check for sinkholes and other issues, apparently for insurance purposes, but found nothing wrong. State law requires home insurers to provide coverage against sinkholes.
"And a couple of months later, my brother dies. In a sinkhole," Bush said Friday.

Fans keep love alive for 'Walking Dead' star
LOS ANGELES (AP) ? From week to week fans simply never know which characters will survive the relentless zombie attacks on AMC's hit series "The Walking Dead."
That unpredictability keeps viewers on the edge of their seats and the shows' stars in a constant state of alertness.
"You see series and they last a long time and sometimes the writing gets lazy or the acting gets lazy. Because we're in a zombie apocalypse and anyone can go at any time, it sort of keeps us fresh and on our toes," Norman Reedus told The Associated Press Friday.
Fans lined up around the block to watch a panel discussion with Reedus and his co-stars at Paleyfest, the annual Southern California TV celebration. Many in the crowd showed their support for Reedus' crossbow-wielding character, Daryl Dixon, with their "If Daryl dies we riot!" T-shirts.
The 44-year-old actor says his vocal fan base is responsible for his character's impressive longevity in a series that seems to have no qualms in axing its most popular characters.
"Hell yes. Oh my god, yes," he said. "(They're) keeping me on the show."
"The Walking Dead" focuses on a rag-tag band of surviving refugees, including unruly brothers Daryl and Merle Dixon, who were not part of the series' comic book origins.
"I want to be Daryl Dixon in my next life," joked co-star Laurie Holden. "He's sexy and he's got the rugged thing going on."
When asked about his breakout star status, Reedus becomes humble and tries to turn the spotlight on his Golden Globe-nominated cast.
"I watch them grow and I watch myself grow. It's one of those acting things where like I'll be in a scene with her or with him and I'll say should I try this? And they'll go 'yeah' and I'll believe them and I'll trust them. Everyone wants everyone to just kill it," Reedus said with a laugh.

Buffett calls year with 45 pct. profit jump subpar
OMAHA, Neb. (AP) ? Most companies would undoubtedly be thrilled with the results Warren Buffett called "subpar" at Berkshire Hathaway because his company's value trailed the overall market.
But the fact that Buffett wasn't satisfied with the 45 percent jump in profit his company reported Friday is part of why he's built such a remarkable record.
Buffett sounded optimistic about both the economy and his company in an annual letter to shareholders that was released Friday. Buffett urged other businesses to either invest in the future or sell their profitable ventures to Berkshire.
"Charlie and I love investing large sums in worthwhile projects, whatever the pundits are saying," Buffett said in reference to Berkshire Vice Chairman Charlie Munger.
So it didn't really matter much that 2012 was only the ninth time in the past 48 years that Berkshire's book value per share failed to outpace the S&P 500's 16 percent growth. Berkshire's value ? calculated by subtracting liabilities from assets ? still grew by 14.4 percent.
The legendary investor also confessed that the two investment managers he hired over the last few years left Buffett in their dust largely, because he didn't make a big acquisition last year.
Berkshire's chairman and CEO had considerably more good news than bad to offer, and Buffett offered more explanation about the company's recent newspaper purchases and its opposition to paying derivatives.
Berkshire's net income soared in 2012 to $14.8 billion, up from $10.3 billion the previous year, but most of the increase came from paper gains on its investments and derivative contracts.
Without those gains, Berkshire's operating earnings advanced 17 percent to $12.6 billion, up from the previous year's $10.8 billion. Nearly all of its major business groups performed well in 2012, with the insurance units that include Geico and General Reinsurance leading the way because of significantly fewer natural disasters in the year.
"Berkshire really did pretty well," said Jeff Matthews, who wrote "Warren Buffett's Successor: Who It Is and Why It Matters."
Buffett said Berkshire's acquisition luck turned last month when he agreed to work with the 3G Capital investment fund to buy the H.J. Heinz Co. for $23.3 billion.
Berkshire will own half the company, receive 9 percent dividends on $8 billion, and get warrants to buy another 5 percent of Heinz. But Buffett and Munger won't be satisfied by the ketchup deal.
"We still have plenty of cash and are generating more at a good clip," Buffett wrote. "So it's back to work; Charlie and I have again donned our safari outfits and resumed our search for elephants."
Andy Kilpatrick, who wrote "Of Permanent Value: The Story of Warren Buffett," said the warrants make it likely that Heinz will one day be entirely owned by Berkshire.
And Buffett said Berkshire finished 2012 with nearly $47 billion on hand, so he does have plenty to work with even if he insists on keeping about $20 billion around in case of emergencies.
Many of the companies Berkshire owns outright ? including MidAmerican Energy, Lubrizol chemicals and HomeServices of America ? together made 26 smaller acquisitions for $2.3 billion last year.
Kilpatrick said he was impressed with the report because for the first time in several years, it looks like all parts of Berkshire are performing well, and it looks like the 82-year-old Buffett is doing well after a prostate cancer scare last year.
"He looks to be in terrific health, and the company looks to be in terrific health," Kilpatrick said.
Buffett did not offer any new details in the letter on the plan to eventually replace him. He has said Berkshire's board plans to split Buffett's job into three roles: CEO, chairman and investment management. The board knows who it would choose immediately to succeed him as CEO.
The investment piece seems set with the recent hiring of hedge fund managers, Todd Combs and Ted Weschler. They manage portfolios worth about $5 billion while Buffett continues to make most of Berkshire's investment decisions. Buffett praised both on Friday.
"Todd Combs and Ted Weschler, our new investment managers, have proved to be smart, models of integrity, helpful to Berkshire in many ways beyond portfolio management, and a perfect cultural fit. We hit the jackpot with these two," Buffett said.
In his letter, Buffett defended the newspaper investments he made last year. But mostly his comments just elaborated on what he's said previously about newspapers that are the primary source of information about their communities will continue delivering decent returns.
Berkshire will own 28 daily newspapers in small and mid-sized cities once its acquisition of the Tulsa World is complete. Berkshire bought 63 Media General newspapers last year for $142 million.
"Wherever there is a pervasive sense of community, a paper that serves the special informational needs of that community will remain indispensable to a significant portion of its residents," Buffett said.
Berkshire owns roughly 80 subsidiaries, including railroad, clothing, furniture and jewelry firms, but its insurance and utility businesses typically account for more than half of the company's net income. The Omaha, Neb., company employs more than 288,000 and holds major investments in such companies as Coca-Cola Co., IBM and Wells Fargo & Co.

How do bacteria clog medical devices? Very quickly
Mar. 1, 2013 ? A new study has exam?ined how bac?te?ria clog med?ical devices, and the result isn't pretty. The microbes join to cre?ate slimy rib?bons that tan?gle and trap other pass?ing bac?te?ria, cre?at?ing a full block?age in a star?tlingly short period of time.
The find?ing could help shape strate?gies for pre?vent?ing clog?ging of devices such as stents -- which are implanted in the body to keep open blood ves?sels and pas?sages -- as well as water fil?ters and other items that are sus?cep?ti?ble to con?t?a?m?i?na?tion. The research was pub?lished in Pro?ceed?ings of the National Acad?emy of Sciences.
Click on the image to view movie. Over a period of about 40 hours, bac?te?r?ial cells (green) flowed through a chan?nel, form?ing a green biofilm on the walls. Over the next ten hours, researchers sent red bac?te?r?ial cells through the chan?nel. The red cells became stuck in the sticky biofilm and began to form thin red stream?ers. Once stuck, these stream?ers in turn trapped addi?tional cells, lead?ing to rapid clog?ging. (Image source: Knut Drescher)
Using time-lapse imag?ing, researchers at Prince?ton Uni?ver?sity mon?i?tored fluid flow in nar?row tubes or pores sim?i?lar to those used in water fil?ters and med?ical devices. Unlike pre?vi?ous stud?ies, the Prince?ton exper?i?ment more closely mim?ic?ked the nat?ural fea?tures of the devices, using rough rather than smooth sur?faces and pressure-driven fluid instead of non-moving fluid.
The team of biol?o?gists and engi?neers intro?duced a small num?ber of bac?te?ria known to be com?mon con?t?a?m?i?nants of med?ical devices. Over a period of about 40 hours, the researchers observed that some of the microbes -- dyed green for vis?i?bil?ity -- attached to the inner wall of the tube and began to mul?ti?ply, even?tu?ally form?ing a slimy coat?ing called a biofilm. These films con?sist of thou?sands of indi?vid?ual cells held together by a sort of bio?log?i?cal glue.
Over the next sev?eral hours, the researchers sent addi?tional microbes, dyed red, into the tube. These red cells became stuck to the biofilm-coated walls, where the force of the flow?ing liq?uid shaped the trapped cells into stream?ers that rip?pled in the liq?uid like flags rip?pling in a breeze. Dur?ing this time, the fluid flow slowed only slightly.
At about 55 hours into the exper?i?ment, the biofilm stream?ers tan?gled with each other, form?ing a net-like bar?rier that trapped addi?tional bac?te?r?ial cells, cre?at?ing a larger bar?rier which in turn ensnared more cells. Within an hour, the entire tube became blocked and the fluid flow stopped.
The study was con?ducted by lead author Knut Drescher with assis?tance from tech?ni?cian Yi Shen. Drescher is a post?doc?toral research asso?ciate work?ing with Bon?nie Bassler, Princeton's Squibb Pro?fes?sor in Mol?e?c?u?lar Biol?ogy and a Howard Hughes Med?ical Insti?tute Inves?ti?ga?tor, and Howard Stone, Princeton's Don?ald R. Dixon '69 and Eliz?a?beth W. Dixon Pro?fes?sor of Mechan?i?cal and Aero?space Engineering.
"For me the sur?prise was how quickly the biofilm stream?ers caused com?plete clog?ging," said Stone. "There was no warn?ing that some?thing bad was about to happen."
By con?struct?ing their own con?trolled envi?ron?ment, the researchers demon?strated that rough sur?faces and pres?sure dri?ven flow are char?ac?ter?is?tics of nature and need to be taken into account exper?i?men?tally. The researchers used stents, soil-based fil?ters and water fil?ters to prove that the biofilm streams indeed form in real sce?nar?ios and likely explain why devices fail.
The work also allowed the researchers to explore which bac?te?r?ial genes con?tribute to biofilm streamer for?ma?tion. Pre?vi?ous stud?ies, con?ducted under non-realistic con?di?tions, iden?ti?fied sev?eral genes involved in for?ma?tion of the biofilm stream?ers. The Prince?ton researchers found that some of those pre?vi?ously iden?ti?fied genes were not needed for biofilm streamer for?ma?tion in the more real?is?tic habitat.
This work was sup?ported by the Howard Hughes Med?ical Insti?tute, National Insti?tutes of Health grant 5R01GM065859, National Sci?ence Foun?da?tion (NSF) grant MCB-0343821, NSF grant MCB-1119232, and the Human Fron?tier Sci?ence Program.
