Closing the gap between fish and land animals
New exquisitely preserved fossils from Latvia cast light on a key event in our own evolutionary history, when our ancestors left the water and ventured onto land. Swedish researchers Per Ahlberg and Henning Blom from Uppsala University have reconstructed parts of the animal and explain the transformation in the new issue of Nature.

New and improved? Novelty drives choice behavior
New research suggests that novelty drives choice behavior in humans, even when the degree of familiarity with an option is completely unrelated to choice outcome. The research, published by Cell Press in the June 26th issue of the journal Neuron, reveals fascinating insights into the brain mechanisms that underlie the tendency to explore, and even value, unfamiliar options.

Binge drinking due to 'copying' behavior

Mothers' influence is decisive in tots' first year
The way mothers interact with their babies in the first year of life is strongly related to how children behave later on. Both a mother's parenting style and an infant's temperament reliably predict challenging behavior in later childhood

Is it harder to raise boys or girls?
Boys' and girls' brains, and their growth, unfold at different rates, influencing behavior. Author Leonard Sax, M.D., believes parents raise girls and boys differently because girls and boys are so different from birth -- their brains aren't wired the same way. So, can we finally answer the great parenting debate over which sex is more challenging to raise?

Estrogen therapy helps or hurts the brain depending on reproductive status
Estrogen therapy may limit stroke damage if started close to, but not long after reproductive cycles are over, according to a new animal study. The results were presented Sunday, June 15, at The Endocrine Society's 90th Annual Meeting in San Francisco.

Drug commonly used for alcoholism curbs urges of pathological gamblers
A drug commonly used to treat alcohol addiction has a similar effect on pathological gamblers – it curbs the urge to gamble and participate in gambling-related behavior, according to a new research at the University of Minnesota.

Tsunami in the brain
After a stroke, even unaffected areas of the brain are at risk – depolarization waves arise at the edges of the dead tissue and spread through the adjacent areas of the brain. If these waves are repeated, more cells die. This has previously been observed only in animal studies.

Fossils found in Tibet revise history of elevation, climate
About 15,000 feet up on Tibet's desolate Himalayan-Tibetan Plateau, an international research team led by Florida State University geologist Yang Wang was surprised to find thick layers of ancient lake sediment filled with plant, fish and animal fossils typical of far lower elevations and warmer, wetter climates.

Has Global Warming Research Misinterpreted Cloud Behavior?
When researchers observe natural changes in clouds and temperature, they have assumed that temperature change caused the clouds to change, and not the other way around. This can lead to overestimates of how sensitive Earth's climate is to greenhouse gas emissions.

Mystery of infamous 'New England Dark Day' solved by 3 rings
At noon, it was black as night. It was May 19, 1780 and some people in New England thought judgment day was at hand. Accounts of that day, which became known as 'New England's Dark Day,' include mentions of midday meals by candlelight, night birds coming out to sing, flowers folding their petals,and strange behavior from animals. The mystery of this day has been solved by researchers.

Brucella abortus S19 genome sequenced; points toward virulence genes
Researchers at the Virginia Bioinformatics Institute at Virginia Tech and the National Animal Disease Center in Ames, Iowa, and collaborators at 454 Life Sciences of Branford, Conn., have sequenced the genome of Brucella abortus strain S19. Strain S19 is a naturally occurring strain of B. abortus that does not cause disease and was discovered by Dr. John Buck in 1923.

Tumor suppressor genes speed up and slow down aging in engineered mouse
Mayo Clinic researchers have developed an animal model that can test the function of two prominent tumor suppressor genes, p16 and p19, in the aging process. Scientists knew that both these genes were expressed at increased levels as humans and mice age, but their role in the aging process was not clear.

Olfactory receptor neurons select which odor receptors to express
It may appear difficult to reconcile the fact that almost every cell in the body of an animal has an identical dose of genes with the variety of different appearances and properties cells can display—bone, skin, hair, muscle, and many more. This may seem even more complex given that all of these tissue types derive originally from a single fertilized egg cell.
