CAIRO (Reuters) - Egypt's deposed leader Hosni Mubarak, who is serving a life sentence for his role in killing protesters during a 2011 revolt, will stay in an army hospital for at least two weeks after his health deteriorated, his lawyer said on Friday.

The state of Mubarak's already fragile health has been the subject of intense speculation in Egypt and he has spent much of the time before and after his trial in various hospitals.

On Thursday evening, the 84-year-old former leader was transferred to an army hospital from his prison clinic after fracturing a rib in a recent fall.

"He will stay in the hospital for about 15 days," Mohamed Abdel Razek, his lawyer, told Reuters.

"The president's health is stable, thank God. He underwent X-rays on his body and now he will get proper treatment in the hospital for all his bone problems he has been suffering from."

Mubarak was toppled after 30 years in power and sentenced to life in prison in June this year. He was admitted to a prison hospital that same month following what security officials described at the time as a "health crisis".

During his trial, Mubarak, the first Arab ruler to be brought to court by his own people, was routinely wheeled into the cage used for defendants in Egyptian courts on a hospital gurney.

He has not spoken publicly about the events that followed his downfall, saying almost nothing at his trial appearances beyond confirming his presence and denying the charges against him.

Mubarak's legal team had been pressing to have him moved from the prison hospital to a better-equipped facility permanently, saying he was not receiving adequate treatment.

But there has been some confusion over the exact nature of his ailments, with state media reporting a variety of illnesses ranging from shortage of breath to heart attacks and comas.

Ormandy and his team grew human breast cancer tissues

cvjhskljffmekwl

HONG KONG (Reuters) - The discovery that a protein which triggers milk production in women may also be responsible for making breast cancers aggressive could open up new opportunities for treatment of the most common and deadliest form of cancer among women.

Found in all breast cells, the protein ELF5 tries to activate milk production even in breast cancer cells, which does not work and then makes the cancer more aggressive, according to scientists in Australia and Britain.

"The discovery opens up new avenues for therapy and for designing new markers that can predict response to therapy," said lead author Professor Chris Ormandy from the Garvan Institute of Medical Research in Sydney.

In 2008, Ormandy's work linked ELF5 to milk production.

The latest research by Ormandy and his team, published in the journal PLOS Biology on Friday, went a step further to find the link between ELF5 and breast cancer.

"Cancer cells can't respond properly (to ELF5), so they ... acquire some characteristics ... that make the disease more aggressive and more refractory (resistant) to treatment with existing therapies," Ormandy said by telephone.

Ormandy and his team grew human breast cancer tissues, genetically manipulated to contain high amounts of ELF5, in petri dishes and saw how the protein proliferated aggressively.

FINDINGS MAY HELP TARGETED THERAPY

Breast cancer is the most commonly diagnosed cancer and the top cause of cancer death among women, accounting for 23 percent of total cancer cases and 14 percent of cancer deaths in women.

To decide on treatment, doctors normally need to find out if the cancer has receptors for the hormones estrogen and progesterone, which, in the case of breast cancer patients, promote growth in their tumors.

Two-thirds of breast cancers are usually positive for estrogen receptors, which then require anti-hormonal therapies that lower estrogen levels in the patient or block estrogen from supporting the growth of the cancer.

For the remaining one-third of patients, their cancers do not have receptors, which means they won't benefit from hormonal therapies. Such patients are usually given other treatments, such as chemotherapy.

Ormandy's team found that cancers with these receptors had low levels of ELF5, while those without receptors had significantly higher levels of the protein.

"What we have shown in this paper is high ELF5 tumors are dependent on ELF5 for their proliferation and if we block ELF5 in high ELF5 tumors, we will block proliferation and that will treat the tumor," Ormandy said.

"If we can develop a drug that targets ELF5, it will be very useful for that group of women," he said.

    A trio of flame shells. The shellfish…

    A huge, colorful shellfish reef discovered off Scotland's west coast could be the largest of its kind in the world, according to the Scottish government.

    Packing at least 100 million bright-orange shells into 4.5 square miles (7.5 square kilometers), the living reef consists of flame shells, a rare saltwater clam found near Scotland. Neon-orange tentacles emerge from between the clam's paired shells, waving gently in the current.

    The flame shell reef is located in Loch Alsh, a sea inlet between the Isle of Skye and the Scottish mainland. The overall population of flame shells in the inlet is likely to exceed 100 million and is the largest known flame shell reef anywhere in the United Kingdom, the Scottish government said in a statement.

    "This important discovery may be the largest grouping of flame shells anywhere in the world," Scottish Environment Secretary Richard Lochhead said in the statement. "And not only are flame shells beautiful to look at, these enigmatic shellfish form a reef that offers a safe and productive environment for many other species."

    Flame shells (Limaria hians) build 'nests' by binding gravel and shells together with thin, wiry threads. The shellfish are around 1.5 inches (4 centimeters) in length and group together in such numbers that they cover the seabed with a felt-like organic reef of nest material several inches thick. Flame shell beds are found in only eight sites in Scottish waters.

    "There were some records of flame shells in Loch Alsh, but scientists had no idea of the bed's true size," said Ben James, marine survey and monitoring manager at Scottish Natural Heritage.

    Heriot-Watt University in Edinburgh carried out the Loch Alsh survey on behalf of Marine Scotland.

    "Too often, when we go out to check earlier records of a particular species or habitat, we find them damaged, struggling or even gone," said Dan Harries, a marine ecologist with the university's school of life sciences. "We are delighted that, in this instance, we found not just occasional patches, but a huge and thriving flame shell community extending right the way along the entrance narrows of Loch Alsh. This is a wonderful discovery for all concerned."

    The Loch Alsh inlet was surveyed as part of a program to identify new Marine Protected Areas, which help defend marine habitat. The reef's discovery strengthens the case for proposing the inlet as a protected area, said Calum Duncan, Scotland program manager for the Marine Conservation Society.

    (Reuters) - A comet blazing toward Earth could outshine the full moon when it passes by at the end of next year - if it survives its close encounter with the sun.

    The recently discovered object, known as comet ISON, is due to fly within 1.2 million miles (1.9 million km) from the center of the sun on November 28, 2013 said astronomer Donald Yeomans, head of NASA's Near Earth Object Program at the Jet Propulsion Laboratory in Pasadena, Calif.

    As the comet approaches, heat from the sun will vaporize ices in its body, creating what could be a spectacular tail that is visible in Earth's night sky without telescopes or even binoculars from about October 2013 through January 2014.

    If the comet survives, that is.

    Comet ISON could break apart as it nears the sun, or it could fail to produce a tail of ice particles visible from Earth.

    Celestial visitors like Comet ISON hail from the Oort Cloud, a cluster of frozen rocks and ices that circle the sun about 50,000 times farther away than Earth's orbit. Every so often, one will be gravitationally bumped out from the cloud and begin a long solo orbit around the sun.

    On September 21, two amateur astronomers from Russia spotted what appeared to be a comet in images taken by a 16-inch (0.4-meter) telescope that is part of the worldwide International Scientific Optical Network, or ISON, from which the object draws its name.

    "The object was slow and had a unique movement. But we could not be certain that it was a comet because the scale of our images are quite small and the object was very compact," astronomer Artyom Novichonok, one of the discoverers, wrote in a comets email list hosted by Yahoo.

    Novichonok and co-discoverer Vitali Nevski followed up the next night with a bigger telescope at the Maidanak Observatory in Uzbekistan. Other astronomers did likewise, confirming the object, located beyond Jupiter's orbit in the constellation Cancer, was indeed a comet.

    "It's really rare, exciting," Novichonok wrote.

    Comet ISON's path is very similar to a comet that passed by Earth in 1680, one which was so bright its tail reportedly could be seen in daylight.

    The projected orbit of comet ISON is so similar to the 1680 comet that some scientists are wondering if they are fragments from a common parent body.

    "Comet ISON…could be the brightest comet seen in many generations - brighter even than the full moon," wrote British astronomer David Whitehouse in The Independent.

    In 2013, Earth has two shots at a comet show. Comet Pan-STARRS is due to pass by the planet in March, eight months before ISON's arrival.

    NASA's Mars Curiosity rover may be able to provide a preview.

    Comet ISON is due to pass by the red planet in September and could be a target for the rover from its vantage point inside Gale Crater.

    The last comet to dazzle Earth's night-time skies was Comet Hale-Bopp, which visited in 1997. Comet 17P/Holmes made a brief appearance in 2007.

    LONDON - Few people keep Queen Elizabeth II waiting, especially when she has issued a personal invitation, but President Ronald Reagan managed to do so in 1982 without causing any lasting damage.

    It happened in 1982, when the Reagan White House failed to reply in a timely way to a personal invitation from the queen for the president and his wife Nancy to stay with her at Windsor Castle during a planned visit to England.

    Formerly Confidential papers made public Friday reveal there were raised eyebrows, and bruised feelings, when Reagan did not answer the sort of invite that usually commands a prompt reply the world over. The queen's invitation was left to languish for weeks — something the British believe is simply Not Done.

    "It is really for the president to respond to her invitation, which he has not done personally, something that I have pointed out several times here," writes Nicholas Henderson, Britain's ambassador to Washington, in a memo to the British Foreign Office. "As you know those surrounding the president are not deliberately rude: It is simply that they are not well-organized and do not have experience of this sort of thing."

    The misunderstanding was eventually cleared up — and Reagan even found the time to go horseback riding with the queen.

    A former Reagan official today offers one possible explanation for the delay replying: Nancy Reagan's need to consult an astrologer.

    "You have to remember that Mrs. Reagan was very strict about his schedule, and she would consult her astrologer to see if this was the right time to travel," William F. Sittman, a special assistant to Reagan who was involved in planning the trip, told The Associated Press. "Sometimes she would back up departures."

    The tiff over the tardy reply is but one revelation contained in nearly 500 pages of newly released documents relating to the Reagan visit being made public Friday by Britain's National Archives. The dossier shows the British government — led by Prime Minister Margaret Thatcher — to be extraordinarily interested in pleasing the relatively new president on his two-day visit.

    British leaders also fretted that perennial cross-Channel rivals might triumph in the tug-of-war for presidential face time in a visit that had to be sandwiched between two summits on the European mainland. They feared the president might cancel, either because of time pressure or a reluctance to offend other European leaders who wanted meetings with Reagan.

    The dossier is filled with serious political concerns — how to maximize Britain's influence on U.S. policy? — and lighter matters, including what gift to give the Reagans (they decided on a carriage clock), and what type of horse and saddle Reagan would most enjoy for his ride with the queen.

    At one point, the president's men pose a fashion question on his behalf: Just what should the president wear to go riding with the queen?

    The answer: Something smart, but casual, of course. Riding boots, breeches and a turtleneck sweater would do fine — no need for formal riding attire.

    The papers show that top Reagan adviser Michael Deaver had a way of annoying his British counterparts with last-minute changes and requests, and also surprised them with some of his objectives. Deaver, remembered as a shrewd image-builder, said he wanted Reagan to be photographed outside of formal venues, so he wouldn't be seen "exclusively in white tie" at palace functions, even suggesting that Reagan go to a village pub to soak up the atmosphere

    The documents make clear that Europe's leaders were desperate for Reagan's attention at a time of high Cold War tensions. A memo from U.K. Cabinet Secretary Robert Armstrong on Feb. 5 expresses concern that a gala, summit-closing dinner at the palace of Versailles outside Paris could delay Reagan's arrival in London. But he warns against pressuring the Reagan entourage to skip the meal at Versailles' Hall of Mirrors because "that would not please the President of the French Republic."

    Reagan's aides also worried the British by suggesting the president might have to skip the stop in London because accepting it might anger the Germans, who had offered a similar invitation. The Americans express concern about "the German problem" — the prospect that if the president visited London he might also have to add a stop in Germany, as well.

    But feelings are smoothed when the Americans assure the British contingent that the Germans are not America's top priority.

    "Eagleburger emphasized how much the president himself wanted to go to London," stresses one confidential memo from the British ambassador, referring to senior U.S. diplomat Lawrence Eagleburger. "There should be no doubt about that. Eagleburger also said that at the moment the Germans were not America's favourite allies."

    There are confidential memos back and forth about whether the London stopover should be officially called a "state visit" — the White House is reluctant to use that phrase for fear of offending the Italians, since a visit to Rome was not designated a state visit.

    The prospect of a chance to relax from international summitry with a bit of horseback riding with the queen seems to have helped carry the day for the Brits. Asked for the president's favourite type of horse, British planners are told simply that he wants a thoroughbred. He ended up riding Centennial, one of the queen's favourites, and wearing a perfectly fitted sports jacket above his sweater, going for an old-time Hollywood look he carried off with ease.

    Much of the actual visit was devoted to pomp and pageantry, or to relaxation, but Reagan did make one speech of consequence. He became the first American president to address a meeting of both houses of Parliament and used the occasion to trumpet his distaste for the Soviet Union, calling it an economic catastrophe.

    He said Marxism-Leninism would be left on the ash heap of history — a prediction that would come to pass in the following decade.

    FALLUJAH, Iraq (AP) — Witnesses say tens of thousands of Iraqi Sunni Muslims have massed along a major western highway in the latest of a week of large demonstrations against the Shiite-led government.

    The protesters gathered Friday near the city of Fallujah, which is in the vast Sunni-dominated province of Anbar west of Baghdad.

    Protesters held aloft placards declaring the day a "Friday of honor." Some carried old Iraqi flags used during the era of ousted dictator Saddam Hussein. Others raised current ones.

    The demonstrations follow the arrest last week of 10 bodyguards assigned to Finance Minister Rafia al-Issawi, who comes from Anbar and is one of the central government's most senior Sunni officials.

    The province has been the scene of several large demonstrations and road blockages since last Saturday.
