Scientists at NASA’s Johnson Space Center found something very unexpected in a Martian crater.
Using the Curiosity Rover, the scientists detected a mineral called tridymite that, until now, they thought could only be created in extremely hot temperatures.
The discovery of this tridymite might rewrite the history of the planet, suggesting that it might once have been hotter than we previously thought, and home to monstrous volcanoes.

A jaw-dropping new photo shows a probable alien planet orbiting a star that lies 1,200 light-years from Earth.
The potential planet appears as a brownish dot to the left of the bright bluish-white star CVSO 30 in the newly released image, which was captured by the European Southern Observatory’s (ESO) Very Large Telescope in Chile.
To appreciate just how fantastic it is to have a direct image of this candidate world, consider that CVSO 30 is about 280 times farther away from Earth than is Alpha Centauri, the star system nearest to our own. [Alien Planet Quiz: Are You an Exoplanet Expert?].

Hyperloop Transportation Technologies (HTT) says it has created a new material that is ten times stronger than steel but 5 times lighter than aluminum. Think about that for a minute. Assuming those claims can be verified, and also assuming the material is not otherworldly expensive, it may take the place of carbon fiber the way Saran Wrap displaced waxed paper.
Small electrical currents appear to activate certain immune cells to jumpstart or speed wound healing and reduce infection when there’s a lack of immune cells available, such as with diabetes, University of Aberdeen (U.K.) scientists have found.
In a lab experiment, the scientists exposed healing macrophages (white blood cells that eat things that don’t belong), taken from human blood, to electrical fields of strength similar to that generated in injured skin. When the voltage was applied, the macrophages moved in a directed manner to Candida albicans fungus cells (representing damaged skin) to facilitate healing (engulfing and digesting extracellular particles). (This process is called “phagocytosis,” in which macrophages clean the wound site, limit infection, and allow the repair process to proceed.)

The world is in the midst of a new arms race, one designed to deliver hypersonic glider weapons — both conventional and nuclear — to one’s adversaries at lightning speed. The U.S. is leading the race at this point, but Russia and China are going to great lengths to make sure that they develop their own boost-glide technology.
Today, the U.S., Russia and China are developing a new class of hypersonic ballistic glider weapons, which within a decade, may render most of the world’s nuclear arsenals vulnerable to lightning-fast penetration and attack.
Although boost-glide [or hyperglide vehicles (HGVs)] weapons would be launched by ballistic missiles and reach hypersonic speeds of at least Mach 5 or more, they would remain maneuverable and largely untrackable after the initial boost phase of their flight. And unlike an intercontinental ballistic missile (ICBM), an HGV’s aerodynamics enables it to generate enough “lift” to potentially glide over distances approaching ten thousand kilometers. All before hitting their targets with accuracies down to a few meters.
“In theory, gliders can either “skip” along the atmosphere like a stone skimming the surface of a pond, or they can glide on a smooth “equilibrium” trajectory,” James Acton, co-director of the nuclear policy program at the Carnegie Endowment for International Peace in Washington, D.C., told me. But the latter smooth trajectory is technically less challenging. Thus, Acton says it appears that’s the one that all three countries are currently developing.

Modern life is punctuated by market cycles.
One year the gears of commerce are whirring along. Businesses are hiring and investing. People are buying houses and cars, televisions and computers. Things are going great. Then a year later, the gears screech to halt—sweeping layoffs, plummeting investment, and crashing markets. No one’s buying anything.
