Twins study shows genetic basis for face and place recognition
12-19-2007 · EurekAlert!New evidence suggests our brains are hardwired before birth to recognize faces and places. But in contrast, the neural circuitry we use to recognize words develops mainly as a result of experience.

- Twin study indicates genetic basis for processing faces, places
12-18-2007 · EurekAlert!
A new study of twins indicates that the genetic foundation for the brain's ability to recognize faces and places is much stronger than for other objects, such as words. The results, which appear in the Dec. 19 issue of the Journal of Neuroscience, are some of the first evidence demonstrating the role of genetics in assigning these functions to specific regions of the brain.

- Genes influence age-related hearing loss
11-14-2007 · EurekAlert!
A new Brandeis University study of twins shows that genes play a significant role in the level of hearing loss that often appears in late middle age. The research, in the Journal of Gerontology: Medical Sciences, examined genetic and environmental factors affecting hearing loss in the frequency range of speech recognition.

- Good behavior, religiousness may be genetic
04-05-2007 · EurekAlert!
A new study in Journal of Personality shows that selfless and social behavior is not purely a product of environment, specifically religious environment. After studying the behavior of adult twins, researchers found that, while altruistic behavior and religiousness tended to appear together, the correlation was due to both environmental and genetic factors.

- Hyperactivity and academic achievement could be linked by genetics
05-17-2007 · EurekAlert!
New research shows that the existence of overactivity, impulsivity and inattentiveness in children who also exhibit poor achievement in math, reading, and language may be due to shared genetic influences. The research was based on 2,000 7-year-old pairs of twins that are part of the UK-based "Twins Early Development Study." The existence of substantial overlap between hyperactivity and achievement has important implications for future research about genes associated with both behaviors.

- A unique twin study on the increased cardiometabolic risk in obesity
02-13-2007 · EurekAlert!
A unique monozygotic twin study by Finnish researchers found that obesity, already in its early stages and independent of genetic influences, is associated with deleterious alterations in the lipid metabolism known to facilitate atherogenesis, inflammation and insulin resistance. By studying monozygotic twins discordant for obesity the research group was able to eliminate effects caused by genetic differences related to obesity and reveal effects attributable to environmental and life-style differences.

- The penalty of having a sister -- why sibling sex matters for male saiga antelopes
03-06-2007 · EurekAlert!
Having a twin sister could put male saiga antelopes at a reproductive disadvantage, says new research published today. The study shows that male twins with a sister are born lighter than those with a brother, making them smaller than the optimal size for males. The research also shows that saigas are the supermums of the hoofed animal world with no other similar species investing more in their offspring during pregnancy.

- Novel MS drug shows promise in 2 lethal leukemias
08-28-2007 · EurekAlert!
A new study suggests that an experimental drug being tested for the treatment of multiple sclerosis and to prevent organ rejection might also help people with certain deadly forms of chronic and acute leukemia. The laboratory and animal study focused on the drug, called fingolimod. Researchers said it might help patients with advanced chronic myelogenous leukemia or acute lymphocytic leukemia, and whose cancer cells show a particular genetic change called the Philadelphia chromosome.

- Small-scale fishing in Mexico rivals industrial fisheries in accidental turtle deaths
10-16-2007 · EurekAlert!
New research shows that a small-scale Mexican fishery -- operated by hand from small open boats -- can kill as many critically endangered loggerhead sea turtles as all of the industrial fishing fleets in the North Pacific Ocean put together. On a per-hook or per-net basis, the Mexican fishery is 10 to 100 times as deadly, the study found.

12-04-2007 · EurekAlert!
Experts have been warning for years that foods loaded with high-fructose corn syrup and other processed carbohydrates are making us fatter. Now, a University of Wisconsin-Madison study has uncovered the genetic basis for why this is so.

- Researchers explore medicine in the final frontier
11-03-2006 · EurekAlert!
Preliminary findings from a University of Florida study show there is little difference in the dose of general anesthesia needed to anesthetize patients in weightless or normal gravity environments. It's a step forward, but just one of many hurdles researchers face in trying to establish proper medical protocols in space.
