DNA-damaged Cells Communicate With Neighbors To Let Them Know They're In Trouble Posted: 14 Jul 2009 08:00 AM PDT When cells experiencing DNA damage fail to repair themselves, they send a signal to their neighbors letting them know they're in trouble. The discovery, which shows that a process dubbed the DDR (DNA Damage Response) also controls communication from cell to cell, has implications for both cancer and aging.

New Cases Of Alzheimer's And Dementia Continue To Rise, Even In The 'Oldest Old' Posted: 14 Jul 2009 08:00 AM PDT The number of people with Alzheimer's, both new cases and total numbers, continues to rise among the oldest segments of the population in contradiction of the conventional wisdom. Previous studies have suggested that the number of people with Alzheimer's begins to level off and perhaps even drop in people age 90 and above, known as the "oldest old."

Major Breakthrough With Water Desalination System Posted: 14 Jul 2009 05:00 AM PDT Engineers have achieved a major breakthrough with a new mini-mobile-modular (M3) smart water desalination and filtration system. The M3, which is portable and can be monitored and operated remotely via the web, showed in a recent field study in the San Joaquin Valley that it can desalt agricultural drainage water that was nearly saturated with calcium sulfate salts at up to 65 percent product water recovery; accomplishing this with just one reverse osmosis stage.

Why HIV Progresses Faster In Women Than In Men With Same Viral Load Posted: 14 Jul 2009 05:00 AM PDT Scientists have found that a receptor molecule involved in the first-line recognition of HIV-1 responds to the virus differently in women, leading to subsequent differences in chronic T cell activation, a known predictor of disease progression.

House Cats Know What They Want And How To Get It From You Posted: 13 Jul 2009 08:00 PM PDT Anyone who has ever had cats knows how difficult it can be to get them to do anything they don't already want to do. But it seems that the house cats themselves have had distinctly less trouble getting humans to do their bidding, according to a new report.

Like Father, Like Son: Childhood Obesity Link To Parents Posted: 13 Jul 2009 08:00 PM PDT The relationships between children and their parent of the same gender in the earliest years of life could be the key to understanding why some young people become obese and others do not, new research has shown.

Number Of Patients With Dementia On The Rise Posted: 13 Jul 2009 08:00 PM PDT By the year 2050, about 30 million Americans are expected to suffer from Alzheimer's disease. Experts in the field are trying to determine if sophisticated imaging equipment can help predict the development of the disease.

Antidepressants Aid Electroconvulsive Therapy In Treating Severe Depression Posted: 13 Jul 2009 08:00 PM PDT Combining antidepressant drugs with electroconvulsive therapy (ECT) does a better job of reducing symptoms of severe depression and causes less memory loss than using ECT alone, according to a new study.

Trapping Carbon Dioxide Or Switching To Nuclear Power Not Enough To Solve Global Warming Problem, Experts Say Posted: 13 Jul 2009 08:00 PM PDT Attempting to tackle climate change by trapping carbon dioxide or switching to nuclear power will not solve the problem of global warming, according to new energy calculations. Scientists have calculated the total energy emissions from the start of the industrial revolution in the 1880s to the modern day. They have worked out that using the increase in average global air temperature as a measure of global warming is an inadequate measure of climate change. They suggest that scientists must also take into account the total energy of the ground, ice masses and the seas if they are to model climate change accurately.

Studies Shed Light On Racial Disparities In Cancer Survival Posted: 13 Jul 2009 08:00 PM PDT Black women diagnosed with breast cancer have a greater chance of dying from the disease than white women, according to a new study.

New Drugs Faster From Natural Compounds Posted: 13 Jul 2009 05:00 PM PDT A researcher isolates a natural compound with promising antimicrobial properties from ocean water. But is it a discovery?
