Whether you’re a Pygmy in the Congolese rainforest or a big-city hipster, certain aspects of music will touch you in the same ways—but others very differently, a study suggests.

“People have been trying to figure out for quite a while whether the way that we react to music is based on the culture that we come from or on some universal features of the music itself,” said co-researcher Stephen McAdams of McGill University in Montreal. “Now we know that it is actually a bit of both.”

The researchers traveled deep into the rainforest to play music to a Continue reading Music cuts across cultures: Certain aspects of our reactions to music universal

Scientists study whale that lives 200 years for clues

A whale that can live over 200 years with little evidence of age-related disease may provide untapped insights into how to live a long and healthy life, biologists say.

In the Jan. 6 issue of the research journal Cell Reports, scientists present the bowhead whale’s complete genome and identify what they say are key differences with other mammals.

Changes in bowhead genes related to cell division, DNA repair, cancer, and aging may have helped increase its longevity and cancer resistance, according to the researchers.

“Our understanding of species’ differences in longevity is very p Continue reading Scientists study whale that lives 200 years for clues

Martian meteorite reveals the planet’s climate billions of years ago

Meteorite hunters plucked a Martian rock from an Antarctic ice field 30 years ago. A new research on that rock, this month reveals a record of the planet’s climate billions of years ago, back when water likely washed across its surface and any life that ever formed there might have emerged.

Scientists from the University of California, San Diego, NASA and the Smithsonian Institution report detailed measurements of minerals within the meteorite in the early online edition of the Proceedings of the National Academy of Sciences this week.

“Minerals within the meteorite hold a snapshot of the planet’s anci Continue reading Martian meteorite reveals the planet’s climate billions of years ago

NASA’s SMAP is ready to get launched

Scheduled for launch on Jan. 29, 2015, NASA’s Soil Moisture Active Passive (SMAP) instrument will measure the moisture lodged in Earth’s soils with an unprecedented accuracy and resolution. The instrument’s three main parts are a radar, a radiometer and the largest rotating mesh antenna ever deployed in space.

Remote sensing instruments are called “active” when they emit their own signals and “passive” when they record signals that already exist. The mission’s science instrument ropes together a sensor of each type to corral the highest-res Continue reading NASA’s SMAP is ready to get launched

Is warfare linked to evolution?

Among an eastern African farming people, males who participate in livestock raids in youth may enjoy greater long-term “reproductive success,” a study has found.

The results could feed into a longstanding debate over whether warfare is a product of evolution. Evolutionary theory holds that characteristics of a species take root because they enhance survival and reproduction. Over generations, this causes advantageous features for an individual to spread throughout a population, while unhelpful characteristics die out.

In the new study, published in the journal Proceedings of the National Academy of Sciences this week, Luke Glowacki and Richard Wrangham of Harvard University traced the number of wives and children of 120 male members of the pastoralist Nyangatom people of Ethiopia and South Sudan.

In the short term, the authors found, men who engaged in livestock raids didn’t have more Continue reading Is warfare linked to evolution?

Body Cameras On Cops can present violence

Body cameras on police officers may reduce abusive behavior both by and against officers, a study has found.

Researchers from the University of Cambridge in the U.K. published the results of an experiment they conducted on the cameras’ effects in Rialto, Calif. in 2012. The year-long study found that use of force by camera-wearing police fell by 59 percent and reports against officers dropped by 87 percent against the previous year’s figures.

While the technology helps capture evidence for potential use in court, its greatest benefit may be preventing escalation to violence in the first place, the investigators said—in short, peop Continue reading Body Cameras On Cops can present violence

Light human skeleton may have come after innovation of agriculture

A recent research proposed that the lightly built skeletons of modern humans arose late in our evolutionary history, and most probably resulted from a less active lifestyle after agriculture spread.

Modern humans have a lightly built skeleton, compared with those of chimpanzees and extinct human species.

In a new study, Habiba Chirchir of the The George Washington University in Washington, D.C. and colleagues examined a type of human bone tissue called trabecular bone, which is relatively light and spongy in structure. Trabecular bone tissue co-exists within the same bones as the more compa Continue reading Light human skeleton may have come after innovation of agriculture

Scientists may be able to restore the lost memories

New UCLA research indicates that lost memories can be restored. It shows some rays of hope for patients in the early stages of Alzheimer’s disease.

For decades, most neuroscientists have believed that memories are stored at the synapses — the connections between brain cells, or neurons — which are destroyed by Alzheimer’s disease. The new study provides evidence contradicting this idea.

“Long-term memory is not stored at the synapse,” said David Glanzman, a senior aut Continue reading Scientists may be able to restore the lost memories
