Is an experienced policymaker a more rational and a more self-interested bargainer than the average person? That is what nearly all prior research has assumed. But a new study from the University of California, San Diego shows just the opposite.

Appearing in the Proceedings of the National Academy of Sciences, the study by David Victor of UC San Diego and colleagues suggests that top decision-makers care even more about fairness than the general population, and the more experience they have, the more they care about striking a fair bargain.

(SACRAMENTO, Calif.) -- Scientists have long known the p53 protein suppresses tumors. However, a recent animal study by UC Davis researchers has uncovered a complicated relationship between p53 and another protein, Rbm38, highlighting how the body calibrates protein levels. Too much Rbm38 reduces p53 levels, increasing the risk of cancer. Too little Rbm38 allows p53 overexpression, causing premature aging. The study was published in the journal PNAS on Dec. 15.

Whole genome sequencing of modern and ancient horses unveils the genes that have been selected by humans in the process of domestication through the latest 5.500 years, but also reveals the cost of this domestication. A new study led by the Centre for GeoGenetics at the University of Copenhagen, in collaboration with scientists from 11 international universities, reports that a significant part of the genetic variation in modern domesticated horses could be attributed to interbreeding with the descendants of a now extinct population of wild horses.

An exciting new special issue of the Canadian Journal of Earth Sciences shines the spotlight on the Danek Bonebed in Edmonton, Alberta and increases our knowledge of Edmonton's urban dinosaurs, especially the iconic hadrosaurid Edmontosaurus.

LANSING, Mich. December 15, 2014 - Cyclists who are preparing for race day may have a new sports drink to give them an edge in recovery: tart cherry juice. A new study published in Applied Physiology, Nutrition, and Metabolism found that Montmorency tart cherry juice helped accelerate recovery, maintain muscle function and reduce certain markers of exercise-induced inflammation among a group of cyclists participating in a simulated road race.

To the casual observer, the colonies of social insects like bees and ants appear to be harmonious societies where individuals work together for the common good. But appearances can be deceiving.

Just in time for Christmas, Simon Fraser University computing science professor Richard Zhang reveals how to print a 3D Christmas tree efficiently and with zero material waste, using the world's first algorithm for automatically decomposing a 3D object into what are called pyramidal parts.

A pyramidal part has a flat base with the remainder of the shape forming upwards over the base with no overhangs, much like a pyramid. A pyramidal shape is optimal for 3D printing because it incurs no material waste and saves print time.

New York (15 December 2014)--A study published today is the first detailed assessment of whether the 8-year Iraq War had an effect on childbearing. The study found that before the war, from 1997 to 2003, adolescent fertility in Iraq was stable at just below 70 births per 1,000 girls aged 15-19. However, soon after the beginning of the war, adolescent fertility rose by more than 30 percent, reaching over 95 births per 1,000 girls in 2010.

A breast cancer specialist and clinical researcher at Women & Infants Hospital of Rhode Island presented research yesterday at the 2014 San Antonio Breast Cancer Symposium showing that adding either the chemotherapy drug carboplatin or the blood vessel-targeting drug bevacizumab to the standard treatment of chemotherapy before surgery helped women who have the basal-like subtype of triple-negative breast cancer.

Baltimore MD-- We would not expect a baby to join a team or participate in social situations that require sophisticated communication. Yet, most developmental biologists have assumed that young cells, only recently born from stem cells and known as "progenitors," are already competent at inter-communication with other cells.

Irvine, Calif., Dec. 15, 2014 - Dangerously high levels of air pollutants are being released in Mecca during the hajj, the annual holy pilgrimage in which millions of Muslims on foot and in vehicles converge on the Saudi Arabian city, according to findings reported today at the American Geophysical Union meeting in San Francisco.

The same species of monkeys located in separate geographic regions use their alarm calls differently to warn of approaching predators, a linguistic analysis by a team of scientists reveals. The study, which appears in the journal Linguistics and Philosophy, reveals that monkey calls have a more sophisticated structure than was commonly thought.

CAMBRIDGE, MA -- A new study from MIT implicates a family of RNA-binding proteins in the regulation of cancer, particularly in a subtype of breast cancer. These proteins, known as Musashi proteins, can force cells into a state associated with increased proliferation.

In 1912, three species in the parasitic wasp genus Ophion were described by two different entomologists, increasing the number of known species in North America to eleven. It has long been known that the actual diversity is much higher; however, it took 102 years for any additional species to be described.

PROVIDENCE, R.I. [Brown University] -- Using a computer algorithm that can sift through mounds of genetic data, researchers from Brown University have identified several networks of genes that, when hit by a mutation, could play a role in the development of multiple types of cancer.
