Using data from NASA’s TIMED satellite, scientists have discovered the existence of hot atomic hydrogen atoms in the thermosphere (from about 56 to 311 miles, or 90-500 km, above the surface), a layer of Earth’s atmosphere. The finding changes current understanding of the hydrogen distribution and its interaction with other …

NASA’s Cassini orbiter has beamed back its first photos of the gas giant Saturn and the planet’s major moons since beginning the so-called ‘ring-grazing’ phase, the latest phase of its mission. This view from Cassini was obtained about half a day before its first close pass by the outer edges …

New data from NASA’s Cassini spacecraft reveal that Saturn’s moons may be younger than previously thought.

ESA’s ExoMars Trace Gas Orbiter (TGO) has sent back its first color image of Phobos, the larger and inner of the two natural satellites of Mars. Color composite of Phobos taken with TGO’s CaSSIS camera on November 26, 2016. The observation was made at a distance of 4,785 miles (7,700 …

On Dec. 11, 2016, NASA’s Juno spacecraft successfully completed its third flyby over Jupiter’s mysterious cloud tops. Jupiter’s ‘pearl.’ Image credit: NASA / JPL-Caltech / SwRI / MSSS. At the time of closest approach, Juno was about 2,580 miles (4,150 km) above the gas giant’s roiling cloud tops and traveling …

Boron, a metalloid chemical element with properties intermediate between those of carbon and aluminum, has been identified for the first time on the Martian surface, indicating the potential for habitable groundwater in the ancient past. The highest concentration of boron measured on Mars is in this mineral vein, called ‘Catabola,’ …

Embattled medical testing firm Theranos has made the decision to get out of the laboratory testing industry. This is a major reversal for the company, following government scrutiny that resulted in a 2-year ban on CEO Elizabeth Holmes running a laboratory. Instead of running labs, Theranos will try selling its …

For people with severe allergies, having a ready supply of epinephrine (also known as adrenaline) can be the difference between a mild inconvenience and death. That’s why the recent price hike on the EpiPen auto-injector manufactured by Mylan was such a hot button issue for patients. The company’s CEO, Heather …

As more and more devices gain connectivity, there are more opportunities for malicious individuals to steal your data, break things, and just generally make your life more difficult. At least you’ll still have your life, though. Now a security firm says that a connected implantable cardiac device made by Minnesota-based …

Breathalyzers to detect alcohol intoxication have existed for years, as the relationship between blood-alcohol content and alcohol in the breath is well understood. The same principles may soon be applied to diabetes screening. A team of researchers from Oxford University have succeeded in building a device that can flag patients …
