Predation Linked To Evolution, Study Suggests

The fossil record seems to indicate that the diversity of marine creatures increased and decreased over hundreds of millions of years in step with predator-prey encounters. For decades, there has been a debate between paleontologists, biologists, and ecologists on the role of ecological interactions, such as predation, in the long term patterns of animal evolution.

Primary Biliary Cirrhosis More Severe In African-American And Hispanic Patients

Non-Caucasian patients seeking medical care for primary biliary cirrhosis have more severe liver disease compared to Caucasian patients, a new study has found. The reasons for the health disparities are unknown, since patients in both groups were of similar age and had the disease for similar lengths of time.

Primates Expect Others To Act Rationally

Researchers have found that when understanding behavior, primates assume rationality and make inferences based on environmental restraints. The researchers studied over 120 primates from the three major groups of primates, and found the same responses among all three types.

Refugia Of Brazilian Atlantic Rainforest Could Be Basis For Its Regeneration

Changes that have occurred in Brazil tropical rainforest for more than 100,000 years were studied by a team of researchers. They combined data from botany, palynology and genetics. Results indicated that the expansion of tropical conifer populations never occurred during interglacial periods, in contrast to what usually happened in the temperate latitudes. Such a finding should be useful for forest conservation in the face of climate change.

Role Of Oxidative Stress In Estrogen-related Bone Loss Illuminated

Scientists have discovered new information about an immune pathway in mice that explains how oxidative stress that results from acute estrogen deficiency leads to the loss of bone. The finding could help in identifying a new drug target for preventing postmenopausal bone loss.

Safer Car Controls

The number of electronic components in cars is growing rapidly. To ensure that vehicle electronics will work properly in future despite the overabundance of software and its increasing complexity, researchers are remodeling it and making it even safer. The sight of a shiny new car suggests streamlined high-tech devices. But appearances are deceptive. Under the hood, all is confusion. Around 100 microprocessors control auxiliary functions such as ABS, ESP or the headlight that can shine around corners. Almost as many control units send their commands to fuel injection systems, airbags and other functional modules.

Social Cues Used By Those With Autism Illuminated

New research suggests that individuals with autism take note of social cues such as eye contact more closely than previously thought, regardless of whether or not they have an additional language impairment. Many researchers believe that poor social understanding lies at the heart of autistic disorders. Testing this hypothesis has traditionally proved tricky as the methods used are often far removed from real life situations and make extra demands on the subject, such as requiring language comprehension and prolonged memory use. Eye-tracking technology is enabling researchers to investigate social processing in situations that are much closer to those experienced in real life.

Teen Binge Drinkers Risk Alcoholism And Social Exclusion As Adults

Teen binge drinkers are significantly more likely to become heavy drinkers as adults and find themselves with a string of criminal convictions, indicates a new study. The researchers monitored the health and prospects of more than 11,000 UK children born in 1970 at the ages of 16 and 30. They collected information on binge drinking during the preceding fortnight and habitual drinking during the previous year from the 16 year olds. One in four of the 16 year olds were habitual drinkers, drinking more than two to three times a week.

When Does Being Obese Not Lead To Diabetes? When Mice Lack Osteopontin

Obesity is one of the biggest risk factors for type 2 diabetes. One reason for this is thought to be the chronic inflammation characterized by macrophage infiltration into adipose tissue that accompanies obesity, because it has been linked to the development of insulin resistance (which in turn often leads to type 2 diabetes).
