It’s a start for developing novel therapies.

The goal of the Paris Agreement is to keep warming below 2 degrees Celsius. This would be more than double that.

Earth’s continents are (very slowly) headed for a collision.

Founder Richard Branson is “pretty confident” it’ll happen.

For some time now, scientists have known that electrical currents can help heal chronic wounds. And while there are electrotherapy units that are in use, they can be quite bulky and complex. That’s why researchers have created an “electric bandage” that’s powered by the motion of the body.

Ph.D. candidate Ernie Hensel claims UAVs can efficiently track, identify, and monitor various species while remaining nonintrusive.

The world is a complicated place. Bayes’ theorem can help us navigate it.

During my first full day here, I broke my first record by generating more electrical power than any previous robot on the surface of Mars. I’m in a sandy area with few rocks, soaking up the Sun. More about where I landed: http://go.nasa.gov/2RvGiMl&h=AT18X8EjCOTXbtitHthnNUzrg5IiHWx…p1W1lBoVnw

The first stars flickered into being a few hundred million years after the big bang. Since then, galaxies have churned out stars at a stupendous rate, and scientists estimate there were now about a trillion trillion.

In total, the astronomers estimate, stars have radiated 4x10⁸⁴ photons (a photon being the smallest unit of light). Or put another way: 4,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 photons.

The astronomers based their calculation on measurements of the extragalactic background light (EBL), a cosmic fog of radiation that has been accumulating since stars first illuminated the dark, vast expanse of space.

Chang’e-4 mission will test plant growth on the Moon, and listen for radio emissions normally blocked by Earth’s atmosphere. Instruments on board the lander will carry out the first radio astronomy observations from the Moon’s far surface.
