The discovery of a biomarker for chronic traumatic encephalopathy (CTE) could lead to diagnosis of the disease in living individuals, something not currently possible.
CTE is a neurodegenerative brain disease thought to be caused by repeated blows to the head, resulting in brain damage that accumulates over time. A recent study of 111 NFL players who donated their brains after death found CTE in all but one of them.

Earth’s first life evolved in hell.
The earliest lifeforms emerged at least 3.95 billion years ago, at a time when a near constant barrage of comets and asteroids were bombarding our still solidifying planet. That’s the implication of new research published in the journal Nature on Wednesday.
A group of Japanese scientists journeyed into ...read more

Last year, physicists made history by observing the first-ever gravitational wave. Their discovery confirmed Albert Einstein’s century-old theory of gravity and capped decades of effort to build an instrument sensitive enough to catch these ripples in spacetime.
Since then, researchers working at the government-funded Laser Interferometer Gravitational Wave Observatory (LIGO) — twin detectors in Louisiana and Washington State — have caught se ...read more

This week, the focus is on the rumbling volcanoes in Indonesia and Vanuatu. Here are some updates (along with a tidbit at the end on Washington’s Rainier.)
Agung
The unrest at Indonesia’s Agung continues and now the total evacuated has reached almost 100,000 people. Now, this volcanic crisis has been going for almost a week with no eruption … and we begin to enter the long, dark teatime of volcano monitoring: h ...read more
With two months left, more records could fall before we’re all done

We’ve known for some weeks now that the 2017 Atlantic Hurricane season has been absolutely brutal.
And now, thanks to new calculations, we have some statistical insights into the raw, howling power of the storms that hav ...read more
Cassini’s mission is over and gone for good. But we’re not done with Saturn yet — it just may be a while before we go back. (Credit: NASA)
By the end of the year, NASA will decide on a new New Frontiers-class mission. This medium-cost mission class is responsible for the Juno, New Horizons, and OSIRIS-REx probes, and has a handful of finalists selected for a mid-2020s launch. Among proposals for a Moon mission, a Venus lander, and a comet sample return are five Saturnian ...read more

The mysterious tale of the giant rat of Sumatra was famously “a story for which the world is not yet prepared,” according to Sherlock Holmes. Now, after years of searching, researchers have discovered a new tree-dwelling, coconut-piercing species of giant rat in the Solomon Islands—it measures 18-inch rodent that researchers finally tracked down after years of searching.

They say that many hands make light work. Well, for African penguins, many beaks make for bountiful hunts, according to a new study in Royal Society Open Science. The results suggest that dwindling populations may have greater consequences than previously realized.
African penguins (Spheniscus demersus), or as some call them “jackass” penguins for their donkey ...read more

There’s energy everywhere, the trouble is harnessing it.
We extract power from wind, waves and sunlight, but researchers from Columbia University say there’s another font of untapped energy — water evaporating from lakes and reservoirs across the country. In a new analysis laying out a prospective plan to harness evaporation, they say that up ...read more

It’s well known that theropods were the ancestors of modern-day birds, but exactly how these dinosaurs made the transition from fearsome maws to toothless beaks has been unclear. A new study from researchers in China shows various adolescent species of toothed theropods actually had both for a time — they transitioned from toothy jaws to beaks during adolescenc ...read more
