Scientists from the Max Planck Institute discovered that women prefer the smell of men who have different immune gene variants than they themselves have, cracking the olfactory code for partner selection and synthesizing the first biologically effective perfume. Individual body odor plays an important role in partner selection. Humans, mice, fish and birds, and probably [...]

A new study from the University of Washington shows that sex between married couples is linked to what types of chores each spouse completes. Married men and women who divide household chores in traditional ways report having more sex than couples who share so-called men’s and women’s work, according to a new study co-authored by [...]

For the first time caught on video, Korean-based scientists witnessed a group of dolphins trying to help another dying dolphin by forming a “life raft.” Details of the behavior are reported in the journal Marine Mammal Science. Publication: Kyum J. Park, Hawsun Sohn, Yong R. An, Dae Y. Moon, Seok G. Choi, Doo H. An, [...]

New research from the University of Utah shows that the people most likely to multitask have the lowest multitasking ability, including people who talk on cell phones while driving. Most people believe they can multitask effectively, but a University of Utah study indicates that people who multitask the most – including talking on a cell [...]

Scientists from the Max Planck Institute have discovered that cooperative relationships between chimpanzees are facilitated by an endocrinological mechanism involving the hormone oxytocin, even when these are between non-kin. Animals which maintain cooperative relationships show gains in longevity and offspring survival. However, little is known about the cognitive or hormonal mechanisms involved in cooperation. Researchers [...]

New research from scientists at the Yale School of Engineering & Applied Science may lead to a better understanding of how local, spontaneous interaction among living things leads to the organization of collective animal motion. The adulthood of a midge fly is decidedly brief — about three days. But a new study of its mating [...]

It appears that college students, and the general public, have one less sexually transmitted health issue to worry about. A Bloomberg news article is reporting that pubic lice, the crab-shaped insects that have dwell in the human groin area, is on the decline. Scientists have noted that the recent trend in pubic hair removal, such [...]

Newborn babies only a few hours old are able to differentiate between sounds from their native language and a foreign one. A new study indicates that babies begin absorbing language while still in the womb, earlier than previously thought. The scientists published their findings in the journal Acta Paediatrica. Sensory and brain mechanisms for hearing [...]

New research indicates that happier people actually earn more money. This comes as a result of a study of 10,000 Americans that showed that those who experienced more positive daily emotions and felt more satisfied with their lives while growing up, earned more income by age 29. The scientists published their findings in the journal [...]

A newly published study found that astronauts going to Mars could have trouble sleeping, become lethargic, and have problems with mental tasks over the course of a long mission. The Mars 520-d experiment is an international test run by the Russian Academy of Science, in conjunction with the ESA and the Chinese space agency. The [...]

Elephants need to consume a minimum of 100 liters of water and 100 kilograms of vegetation daily, yet a small population of 350 manages to survive in the harsh Gourma region of Mali, south of the Niger River, where temperatures spike to 50˚C and vegetation is sparse. The scientists published their findings in the journal [...]

According to a new study, many people underestimate how much they will change in the future. The scientists published their findings in the journal Science¹. Many of the choices that people make rest on assumptions. The psychologists devised a series of online experiments, in which more than 19,000 people participated. Adults between 18 and 68 [...]
