A symphony of second opinions on Mozart’s final illness
2016-12-10
For classical music lovers, December 5 may be the saddest day of the year. At 12:55 a.m., 225 years ago, Wolfgang Amadeus Mozart drew his last breath. Later, he was unceremoniously buried in a common grave — as was the custom of his era — in the St. Marx cemetery, just outside the Vienna city limits. Mozart was only 35.

Child Mummy Could Rewrite Smallpox Timeline
2016-12-10
The oldest genetic sample of smallpox ever studied could rewrite the timeline for this deadly disease, which ravaged Europe and much of the world beginning in the eighteenth century.

Cancer spread is increased by a high fat diet, ground-breaking evidence shows
2016-12-10
New research shows that the metastatic process (cancer spread) is enhanced by fat intake. Mice given a high fat diet, including palmitic acid (a major component of palm oil which is found in lots of household products) developed the most aggressive cancer spread. The study identifies for the first time a protein called CD36 which has an essential role in cancer spreading.

The Dino-Chickens Are Coming
2016-12-09
"I'm not talking half a century here; I'm talking decades. It's going to happen." A few years ago Bhart-Anjan Bhullar, then a Ph.D. student in Arhat Abzhanov’s lab at Harvard, did something pretty incredible: He took an embryonic chicken and inhibited a couple of genes during its development. It was a tiny adjustment that produced a pretty amazing result: “Those chickens that were altered in that way, they grew up to have a snout that looked like a dinosaur snout,”

Cognitive science backs up the ancient Indian philosophy that we’re conscious even in deep sleep
2016-12-09
Deep, dreamless sleep is often described as unconsciousness. We certainly don’t see distinct objects or have linear and memorable trains of thought, as we do in daily life or while dreaming. But in a meta-analysis published last month in Trends in Cognitive Sciences, cognitive science experts argue that there is no clear line of consciousness between dreaming and deep sleep.

Substance present in ayahuasca brew stimulates generation of human neural cells
2016-12-08
Ayahuasca is a beverage that has been used for centuries by Native South-Americans. Studies suggest that it exhibits anxiolytic and antidepressant effects in humans. One of the main substances present in the beverage is harmine, a beta-carboline which potential therapeutic effects for depression has been recently described in mice. "It has been shown in rodents that antidepressant medication acts by inducing neurogenesis. So we decided to test if harmine, an alkaloid with the highest concentration in the psychotropic plant decoction ayahuasca, would trigger neurogenesis in human neural cells"

German Lunar Mission To Put Moon Landing Hoax Claims To Rest
2016-12-08
As soon as the Apollo 11 footage hit the airwaves, people began making claims that the footage was somehow faked and that the moon landings were a hoax altogether.

Fish fossils reveal how tails evolved, Penn professor finds
2016-12-07
Despite their obvious physical differences, elephants, lizards and trout all have something in common. They possess elongated, flexible structures at the rear of their bodies that we call tails.

Mexico Is Hiding The World’s Largest Pyramid

MEXICO CITY—In 1519, Hernán Cortés and his conquistadors arrived in Cholula, one of the largest cities in central Mexico. Roughly 50 miles southeast from modern day Mexico City, its tens of thousands of residents sat in the shadows of the 17,000 foot Popocatépetl volcano. It had a temple featuring more stairs, claimed one Spaniard, than the main pyramid in Tenochtitlan.
