From Terror To Joy: Faced With Death, Our Minds Turn To Happier Thoughts

Philosophers and scientists have long been interested in how the mind processes the inevitability of death, both cognitively and emotionally. One would expect, for example, that reminders of our mortality--say the sudden death of a loved one -- would throw us into a state of disabling fear of the unknown. But that doesn't happen. If the prospect of death is so incomprehensible, why are we not...

Glue Inside The Cell

Ubiquitin is a small protein, which can be attached to other cellular proteins. A study now reports a novel finding about ubiquitination as a key event for the activation of an immune response. The acquired immune response is triggered after specific engagement of foreign peptides (antigens) by receptor molecules on white blood cell (lymphocytes).

'Nanospikes' Add To Solar, Biomedical, Microelectronics Applications

New technology under development could lead to more successful hip and bone replacement surgeries, make better use of solar power and even prevent your computer from overheating. Through the creation of nano micro laser texturing and "nanospikes" on the surfaces of semiconductors and metals scientists are adding a new dimension to these materials' effectiveness.

Early Day Care Attendance May Protect Infants From Asthma Later

Day care attendance early in life seems to protect infants and young children from later developing asthma, according to new research. Scientists examined the relationship between the age at which day care attendance begins and the amount of immunoglobulin E (IgE) in a child's blood. IgE is an antibody produced by the immune system and an indicator of allergic sensitivity.

How Hormones Achieve Their Effects

New insights into the cellular signal chain through which pheromones stimulate mating in yeast have been gained by scientists at the European Molecular Biology Laboratory. Similar signal chains are found in humans, where they are involved in many important processes such as the differentiation of nerve cells and the development of cancer. A sophisticated microscopy technique allowed the...

Zinc May Reduce Pneumonia Risk In Nursing Home Elderly

Maintaining normal serum zinc concentration in the blood may help reduce the risk of pneumonia development in elderly nursing home residents. Study participants with normal serum zinc concentrations in their blood reduced their risk of developing pneumonia by about 50 percent.

Comcast Says It Delays, Doesn't Block P2P Traffic

Comcast entered spin control mode on Monday after an Associated Press story revealed that the cable company limits access to BitTorrent and other file-sharing networks. AP reported Friday that Comcast "aggressively" interrupts peer-to-peer file uploads by sending "TCP reset packets" that appear to be coming from the user's computer. Comcast originally denied that it engaged in any kind of...

EPA Faces California Lawsuit over Auto Emissions

California's attorney general plans to sue the Environmental Protection Agency. Attorney General Jerry Brown hopes to force the EPA to decide whether to allow 12 states, including California, to impose stricter standards on vehicle emissions. The lawsuit could be filed as early as Wednesday in a Washington, D.C. federal court. Brown's move comes 22 months after California made its initial...

Massive Rise Reported in Global CO2

Just days after the Nobel Prize was awarded for global warming work, an alarming new study finds that carbon dioxide in the atmosphere is increasing faster than expected. Carbon dioxide emissions were 35 percent higher in 2006 than in 1990, a much faster growth rate than anticipated, researchers led by Josep G. Canadell, of Australia's Commonwealth Scientific and Industrial Research...

China Launching Lunar Probe This Week

China will launch its first lunar probe this week, an official said Monday -- weeks after regional rival Japan put one in high orbit over the moon in a big leap forward in Asia's undeclared space race. The rivalry is likely to be joined soon by India, which plans to send its own lunar probe into space in April. The launch window for China's Chang'e 1 orbiter has been set for Wednesday...

Government Plans for Flu Pandemic

Pregnant women, babies and toddlers would join doctors, emergency workers and soldiers at the head of the line for scarce vaccine if a super-strain of flu triggers the next pandemic, says a draft U.S. government plan to be released Tuesday. Once more vaccine is brewed, older children along with workers who keep the electricity, water and phones running could be next to roll up their sleeves....

More Educated People Who Develop Dementia Lose Their Memory Faster

People with more years of education lose their memory faster than those with less education in the years prior to a diagnosis of dementia, according to a new study."Higher levels of education delay the onset of dementia, but once it begins, the accelerated memory loss is more rapid in people with more education," says the study author.
