On 20 May 1916, Ernest Shackleton, Frank Worsley, and Tom Crean reached Stromness, a whaling station on the north coast of South Georgia. They had been walking for 36 hours, in life-threatening conditions, in an attempt to reach help for the rest of their party: three of their crew were stuck on the south side of the island, with the remainder stranded on Elephant Island.
Watch what you say, or rather, how you say it. People judge how confident you are in just 0.2 seconds.
Having a high sense of purpose in life may lower your risk of heart disease and stroke, according to a new study led by researchers at Mount Sinai St. Luke's and Mount Sinai Roosevelt and presented on March 6 at the American Heart Association's EPI/Lifestyle 2015 Scientific Sessions in Baltimore.
It has qualities so remarkable, it could come from the land of Oz (and could become the television doctor's next big thing, too): a compound derived from a tree growing in South and Central America prompted obese mice to lose 20% to 30% of their weight. It also allowed normal, healthy mice to chow down on fatty foods -- as much as they wanted -- and never become obese, accumulate excess fat or develop diabetes.
Paul Andrews of McMaster University in Ontario surveyed 50 years' worth of research supporting the serotonin theory of depression, which suggests that the disease is caused by low levels of the "happiness" neurotransmitter, serotonin.

No significant change in home habits of smokers have been observed in the aftermath of a ban on smoking in public spaces, researchers report. Greater inspiration to kick the habit likely comes from having friends or family who set an example by giving up cigarettes themselves, the authors write.

A toilet, conveniently situated near the Student Union Bar at the University of the West of England, is proving that urine can generate electricity.

Three engineering physics students at the University of British Columbia have developed a desktop plastic recycler and extruder that turns plastic waste into the material needed for 3D printing.
A little girl lines up plastic letters fitted with QR codes in front of a little humanoid robot. The robot struggles to reproduce them on a tablet -- especially the loop of the letter p. The girl kindly steps in to help, writing out the word to show the robot how to do it. She puts in effort to teach the robot... without realizing that in reality she is the one who is improving her writing skills. Yesterday, EPFL researchers presented their new teaching tool, called CoWriter, at the "Conference on Human-Robot Interaction (HRI)," an important event in the field of interactive robotics, held in Portland, USA.
Even though mimiviruses are some of the largest viruses we know of, they measure only one tenth the width of a human hair at their largest. Understanding the structure of something so small is not an easy task, so researchers have been working to find different ways to look inside it. In a paper published today in Physical Review Letters, researchers from Uppsala University in Sweden used a new technique to make a 3D reconstruction of the large virus out of almost 200 x-ray snapshots.
Over 10 days in December 1995, the Hubble Space Telescope took 342 images of the same tiny patch of sky in the constellation Ursa Major. The resulting data set, the Hubble Deep Field, revolutionized the study of the early universe by revealing the profusion of galaxies in that faint and distant era when the first galaxies were forming.

Dawn has arrived. The signal was received at 5:36 a.m. PST Friday: NASA's Dawn spacecraft had successfully entered into orbit around Ceres, becoming the first NASA mission to visit a dwarf planet, and the first to go to two distinct bodies in the solar system.
Astronomers have watched a pulsar some 25,000 light-years from Earth slip from view, swallowed by a warp in the fabric of spacetime. This wacky effect is one more proof of Einstein's general theory of relativity, 100 years after publication.
A star-forming cosmic powerhouse represents the best evidence of how galaxies in the early universe evolve.
For only the second time, an exoplanet living with an expansive family of four stars has been revealed.
New experiments show that the asteroids that slammed into Earth and the Moon more than four billion years ago were vaporized into a mist of iron. The findings, published in Nature Geoscience, suggest that the iron mist thrown up by these high velocity impacts was fast enough to escape the Moon’s gravity, but stayed gravitationally stuck on the more massive Earth. And these results may help explain why the chemistry of the Earth and the Moon differ.
A massive ancient ocean once covered nearly half of the northern hemisphere of Mars making the planet a more promising place for alien life to have gained a foothold, Nasa scientists say.
