Shorter sleep may speed brain aging

Man sleeps during final of Gold Cup British Open Polo Championship match at Cowdray ParkBy Shereen Lehman NEW YORK (Reuters Health) – With less sleep, normal aging-related structural changes in the brain progress slightly faster in middle-aged and older people, according to a new brain imaging study. Sleep troubles are more common with age, and shrinkage of certain brain structures is normal. “Among older adults, sleeping less will increase the rate their brain ages and speed up the decline in their cognitive functions,” said lead study author Dr. June Lo, a researcher with Duke-NUS Graduate Medical School in Singapore. Plenty of past research has shown that lack of sleep can worsen fuzzy thinking and memory problems in the short term, and at all ages, Lo and her colleagues note in the journal Sleep.

WTC cleanup workers may renew health claims: U.S. appeals court

CLEANUP CONTINUES AT WORLD TRADE CENTER.By Jonathan Stempel NEW YORK (Reuters) – A federal appeals court in New York has revived claims by 211 cleanup workers who sought compensation for their alleged exposure to toxic contaminants in buildings near the World Trade Center site after the Sept. 11, 2001, attacks. The 2nd U.S. Circuit Court of Appeals on Thursday said a lower court judge erred in dismissing the claims, after the workers had answered "none" when asked if they had been "diagnosed" with ailments, injuries or diseases. These workers were employed by cleaning companies hired by Verizon Communications Inc, Brookfield Properties and dozens of other owners of downtown Manhattan buildings damaged or destroyed in the attacks, the court said. "The fact that plaintiffs answered 'none' to the interrogatory was an insufficient basis, by itself, for a blanket conclusion that all 211 plaintiffs could not establish their claims against defendants as a matter of law," Circuit Judge Denny Chin wrote for a three-judge 2nd Circuit panel.

World cities, home to most people, to add 2.5 billion more by 2050:UN

More than half of the world’s seven billion people live in urban areas, with the top “mega cities” – with more than 10 million inhabitants – being Tokyo, Delhi, Shanghai, Mexico City and Sao Paulo, according to a United Nations report on Thursday. Indeed, urbanization, combined with overall population growth, will boost the number of people in cities by 2.5 billion over the next three decades, with much of that growth in developing countries, especially in Africa. The key challenge for these countries will be meeting the needs of their growing urban population with basic services like education, health care, housing, infrastructure, transportation, energy and employment. “Managing urban areas has become one of the most important development challenges of the 21st century,” said John Wilmoth, Director of the Population Division in the UN’s Department of Economic and Social Affairs.
