Disruption Of Circadian Rhythms Affects Both Brain And Body, Mouse Study Finds Posted: 28 Oct 2009 11:00 AM PDT A new study has found that chronic disruption of one of the most basic circadian (daily) rhythms -- the day/night cycle -- leads to weight gain, impulsivity, slower thinking, and other physiological and behavioral changes in mice, similar to those observed in people who experience shift work or jet lag.

Tsunami Evacuation Buildings: Another Way To Save Lives In The Pacific Northwest Posted: 28 Oct 2009 11:00 AM PDT Coastal towns and cities in the northwest are woefully unprepared for a large-scale natural disaster.

Deadly Stomach Infection Rising In Community Settings, Study Finds Posted: 28 Oct 2009 11:00 AM PDT Researchers have found that a sometimes deadly stomach bug, Clostridium difficile, is on the rise in outpatient settings. Clostridium difficile is a serious bacteria that can cause symptoms ranging from diarrhea to life-threatening inflammation of the colon.

Scientists Use World's Fastest Supercomputer To Create The Largest HIV Evolutionary Tree Posted: 28 Oct 2009 11:00 AM PDT In a new study the evolutionary history of more than 10,000 sequences from more than 400 HIV-infected individuals was compared. The idea is to identify common features of the transmitted virus, and attempt to create a vaccine that enables recognition the original transmitted virus before the body's immune response causes the virus to react and mutate.

Pain Of Torture Can Make Innocent Seem Guilty Posted: 28 Oct 2009 11:00 AM PDT Psychologists have found that the more a person appears to suffer when tortured, the guiltier they are perceived to be. According to the researchers, those complicit with the torture need to justify the torture, and therefore link the victim's pain to blame.

Globalization: Diseases Spreading From Humans To Animals, Study Finds Posted: 28 Oct 2009 08:00 AM PDT Globalization and industrialization are causing diseases to spread from humans to animals, a study has shown. Researchers have shown that a strain of bacteria has jumped from humans to chickens.

Combination Antiretroviral Therapy Effective At Reducing HIV Resistance In Mothers And Babies Following Mother-to-child Transmission Posted: 28 Oct 2009 05:00 AM PDT In a clinical trial investigating mother-to-child HIV transmission in South Africa researchers find that adding two other antiretroviral drugs to single dose nevirapine -- an antiretroviral drug given to women and newborn children during labor and delivery to prevent transmission -- is effective in reducing the drug resistance that nevirapine causes when used by itself.

Saving Sand: South Carolina Beaches Become A Model For Preservation Posted: 28 Oct 2009 05:00 AM PDT While most people head to Myrtle Beach for vacation, a group of scientists have been hitting the famous South Carolina beach for years to figure out how to keep the sand from washing away. Their work is a model for beach preservation that can apply elsewhere.

Changes In Brain Chemicals Mark Shifts In Infant Learning Posted: 28 Oct 2009 05:00 AM PDT When do you first leave the nest? Early in development infants of many species experience important transitions -- such as learning when to leave the mother's protection to start exploring the world. Neuroscientists have now pinpointed molecular events occurring in the brain during that turning point. The findings, in animals, may help explain the strength of attachments in many species -- including the conundrum of why human children form strong attachments to even abusive caregivers.

Ocean Acidification May Contribute To Global Shellfish Decline Posted: 28 Oct 2009 02:00 AM PDT Relatively minor increases in ocean acidity brought about by high levels of carbon dioxide have significant detrimental effects on the growth, development, and survival of hard clams, bay scallops, and Eastern oysters, according to researchers.

Secrets In A Seed: Clues Into The Evolution Of The First Flowers Posted: 27 Oct 2009 11:00 PM PDT Researchers have explored a piece of Darwin's "abominable mystery" -- how flowering plants originated, rapidly diversified, and rose to dominance -- by exploring the microscopic anatomy of seed development in Trithuria, a genus in the plant family Hydatellaceae. This family is thought to be one of the earliest families of angiosperms -- the so-called "basal angiosperms."

Location Of Body Fat Affects Risk Of Blood Clots In Men, Women Posted: 27 Oct 2009 11:00 PM PDT The risk of life-threatening blood clots increases with obesity, but may also depend on the location of excess body fat and gender. Women are at higher risk when they carry extra pounds on their hips, while men are at elevated risk when fat is around the waist. The results challenge research that has suggested increased hip circumference is protective against blood clots.

Effort Launched To Find And Control Diseases That Move Between Wildlife And People Posted: 27 Oct 2009 11:00 PM PDT In hopes of preventing the next global pandemic and a possible death toll into the millions, researchers have launched an unprecedented international effort to find and control diseases that move between wildlife and people.

The clinical observational study followed 170,024 ethnically diverse Californians and found that offering lovastatin and lisinopril daily for two years reduced risk of hospitalization for heart attack or stroke by more than 60 percent.

Thinking About The Box Posted: 27 Oct 2009 11:00 PM PDT By re-thinking ideas about packaging size and shape, major environmental gains can be made.

Migratory Route Of Eleonora's Falcon Revealed For First Time Posted: 27 Oct 2009 08:00 PM PDT Satellite tracking has allowed a research team to uncover the mysteries of the migration of Eleanora's falcon for the first time. In total, the bird flies more than 9,500 kilometers across the African continent from the Balearic and Columbretes Islands before reaching the island of Madagascar. Some of the previously-obscure secrets now revealed by the scientists show that these falcons migrate by both day and night, and cross supposed ecological barriers such as the Sahara Desert.

With 22 of the restricted-range species of the Timor and Wetar Endemic Bird Area found so far, Mount Mundo Perdido has been recognized as Timor-Leste's seventeenth Important Bird Area.

Exposure To Alkaline Substances Can Result In Damaged Teeth Posted: 27 Oct 2009 05:00 PM PDT It has long been known that acids can erode tooth enamel but a new Swedish study shows that strong alkaline substances can damage teeth too -- substances with high pH values can destroy parts of the organic content of the tooth, leaving the enamel more vulnerable.

Novel Evolutionary Theory For The Explosion Of Life Posted: 27 Oct 2009 05:00 PM PDT The Cambrian Explosion is widely regarded as one of the most relevant episodes in the history of life on Earth, when the vast majority of animal phyla first appear in the fossil record. However, the causes of its origin have been object of debate for decades. A novel theory formulates that the geologically induced increase on marine calcium, as a result of volcanic activity, might be the key for understanding this important stage in evolution.
