Monkeys’ reaction to those who have more? Spite
2016-01-17
Monkeys, like humans, will take the time and effort to punish others who get more than their fair share, according to a new study. In fact, they can act downright spiteful. Capuchin monkeys will yank on a rope to collapse a table that is holding a partner monkey's food. While chimpanzees collapse their partner's table only after direct personal affronts like theft, capuchins punish more often, even in cases where the other monkey merely had more food, according to a new study.
Genes may contribute to making some nations happier than others
2016-01-17
The citizens of nations that rate themselves happiest display a specific genetic feature: their DNA is more likely to contain a specific allele involved in sensory pleasure and pain reduction, say researchers. They weighed up genetic and various external factors to might contribute to national differences in happiness. Alt: Do YOU have the happiness gene? It may depend where you live: Sweden and Ghana have lots of cheery DNA, but it's bad news for the Chinese and Jordanians

Sixth-century wooden foot thought be Europe’s oldest prosthetic implant
2016-01-16
Archaeologists in Austria believe they have found Europe’s oldest prosthetic implant – a sixth-century wooden foot. The discovery was made in the grave of a man missing his left foot and ankle at Hemmaberg, southern Austria. At the end of his leg was an iron ring and remnants of a clump of wood and leather.
Prosthetic Leg Found Attached to 2,000-Year-Old Remains

The man’s tomb is one of 30 excavated by archaeologists, his remains were found with the prosthetic still attached to his deformed knee.
There’s Something Surprising Lurking in Ceres’ Mysterious Bright Spots
2016-01-16
Dwarf planet Ceres’ bright spots are perhaps the strangest of all its features. Now we’re finally in a low-enough altitude to get an unprecedented close-up look—and what we’re seeing may only have deepened the mystery. NASA’s Dawn spacecraft swung into its lowest orbit yet—a cool cruising height of 240 miles and started snapping pictures of a variety of features of the dwarf planet.
Two types of water ice have been confirmed on the surface of comet 67P
2016-01-16
For the first time, scientists have confirmed the existence of large patches of water ice on the surface of a comet, saying it’s likely formed a dry, crunchy coating over an ice-layered core of the iconic comet called 67P/Churyumov-Gerasimenko. The discovery solves a months-long mystery over why water has been identified everywhere else on the comet except its surface.
Not All Gravitational Waves Are Created Equal
2016-01-16
In physics circles a sense of déjà vu is setting in—breathless headlines have recently championed a possible discovery of gravitational waves, or ripples in the fabric of spacetime. Less than a year ago the same thing happened, although that time the team behind the Background Imaging of Cosmic Extragalactic Polarization 2 (BICEP2) experiment claimed a discovery that turned out to be a mistake. Time will tell if the new potential detection, about which rumors have swirled in lieu of any official announcement by the Laser Interferometer Gravitational-Wave Observatory (LIGO), will turn out to be real.

Oetzi Has No Living Female Relatives
2016-01-16
Oetzi the Iceman has no living female relatives, as his maternal genetic branch is now extinct, says a new research into the genetic history of the 5,300-year-old mummy. According to the study, the Iceman’s maternal line appears to have originated and died out in the eastern Italian Alps. On the other hand, his paternal lineage is still observed in Europe, and new male relatives, alive and well, may be possibly added to the list of the mummy’s descendants.

It started as a normal email exchange with a tech CEO. He was up for a coffee, and passed me to his assistant to find a date. But then it turned a bit strange. Her emails were too good: all written in the same carefully casual, slightly humourless style. All formatted the same. All sent at socially convincing times. And all at believable intervals from my own messages. But they were off just a little.

Scientists bust myth that our bodies have more bacteria than human cells
2016-01-15
It's often said that the bacteria and other microbes in our body outnumber our own cells by about ten to one. That's a myth that should be forgotten, say researchers in Israel and Canada. The ratio between resident microbes and human cells is more likely to be one-to-one, they calculate.

What Will It Take for Humans to Colonize the Milky Way?
2016-01-14
The idea that humans will eventually travel to and inhabit other parts of our galaxy was well expressed by the early Russian rocket scientist Konstantin Tsiolkovsky, who wrote, “Earth is humanity’s cradle, but you’re not meant to stay in your cradle forever.” Since then the idea has been a staple of science fiction, and thus become part of a consensus image of humanity’s future. Going to the stars is often regarded as humanity’s destiny, even a measure of its success as a species.

This discovery may assist in the earlier diagnosis and management of these patients.

If life is effectively an endless series of photocopies, as DNA is transcribed and passed on from one being to the next, then evolution is the high-stakes game of waiting for the copier to get it wrong. Too wrong, and you’ll live burdened by a maladaptive mutation or genetic disorder. Worse, you might never live at all.

Homer’s Iliad—a 3,000-year-old epic poem—continues to shape how we think about war. “Every adjective evokes the destruction and tragedy of war,” says Caroline Alexander, author of The Iliad: A New Translation. Alexander, a frequent contributor to National Geographic, has made her name writing about modern-day epics like the Mutiny on the Bounty and Shackleton’s Antarctic expedition. But Homer has been what the trained classicist calls “the abiding passion of my heart.”

2016-01-11
A shorter working week could improve our mental and physical health and even mitigate climate change, research shows I worked 100-hour plus weeks as a hospital doctor in the early 1990s.
