Scientists build a heat shield just 10 atoms thick to protect electronic devices

This greatly enlarged image shows four layers of atomically thin material forming a heat shield only two to three nanometers thick, or about 50,000 times thinner than a sheet of paper . Credit: National Institute of Standards and Technology Excess heat emitted by smartphones, laptops and other electronic devices can be annoying, but beyond that it contributes to malfunctions and …

Flexible stick sensors can wirelessly monitor your sweat and heart rate – TechCrunch

As people strive ever harder to quantify every action they do, the sensors that monitor these actions become easier and less invasive. Two prototype sensors from crosstown rivals Stanford and Berkeley stick to the skin and provide a wealth of physiological data. Stanford's stretchable wireless "BodyNet" is not only flexible for survival, worn on the body's changing surface; that the …

A massive star completely destroyed by a Supernova is puzzling scientists

The Supernova 2016iet is an example of one of the most extreme types of stellar explosions, although it has some odd features. (Credit: Gemini Observatory / NSF / AURA / illustration by Joy Pollard) In November 2016, the sharp-eyed Gaia spacecraft spied a supernova that exploded a few billion light years from Earth. Astronomers followed up with more telescopes and …

A doomed comet just fell into the sun. Here is the video.

Yesterday (August 15), the Solar and Heliospheric Observatory (SOHO) saw a comet face its demise as the dirty snowball pigeon directly in the sun, according to Space Weather astronomer Tony Phillips . [19659002] In the video taken by SOHO, you can see a number of objects zooming around the sun, which is blocked by an opaque disk to reduce glare. …

Half of the Neanderthal population suffered from Surfer's Ear!

A new study suggests that Neanderthals are often affected by "swimmer's ear" or "surfer's ear" – dense bony growths that protrude into the ear canal. This is usually caused by a common exposure to cold water or cool air, and researchers believe that its presence shows that Neanderthals liked to fish and collect marine resources. Prevalence of Swimmer's Ear in …

Astronomers probably only saw a black hole swallow a neutron star

About 900 million years ago, a black hole released a terrible gap that came through the cosmos. On August 14, the resulting ripples in the fabric of space passed through Earth – providing us with the best evidence yet of an unprecedented type of cosmic collision that can provide new insights into how the universe works. The discovery, called S190814bv, …

The moon is brighter than the sun in these NASA Gamma-Ray Telescope Views

The sun is the brightest object in our sky – but it would not be if we could see incredibly energetic gamma rays as well as visible light. That's exactly the light that NASA's Fermi Gamma-ray Space Telescope is tailor made to see. The instrument launched in 2008 to help astrophysicists understand objects such as super-massive black holes, pulsars and …

The failed Israeli lunar lander Beresheet had a secret biological payload

Facepalm: When Israel sent its lunar lander to the moon earlier this year, there were some biological stowaways on board. Specifically, microscopic organisms called tardigrades were erected and may have spread after the ship crashed. Back in February, Israeli space launch SpaceIL launched a lunar lander, called Beresheet, on a SpaceX rocket. It would be the country's first attempt to …
