NASA Receives Eighth Consecutive Clean Financial Audit Opinion

NASA has received an unmodified audit opinion on its Fiscal Year 2018 financial statements, marking the eight consecutive "clean" opinion from an external auditor – the highest opinion that may be received.

Scientists provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"—the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion—in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Fullerene compounds made simulation-ready

What in the smart nanomaterials world is widely available, highly symmetrical and inexpensive? Hollow carbon structures, shaped like a football, called fullerenes. Their applications range from artificial photosynthesis and nonlinear optics to the production of photoactive films and nanostructures. To make them even more flexible, fullerenes can be combined with added nanostructures. In a new study published in EPJ D, Kirill B. Agapev from ITMO University, St.

The kilogram is being redefined – a physicist explains

How much is a kilogram? 1,000 grams. 2.20462 pounds. Or 0.0685 slugs based on the old Imperial gravitational system. But where does this amount actually come from and how can everyone be sure they are using the same measurement?

Cold neutrons used in hot pursuit of better thermoelectrics

Thermoelectric devices are highly versatile, with the ability to convert heat into electricity, and electricity into heat. They are small, lightweight, and extremely durable because they have no moving parts, which is why they have been used to power NASA spacecraft on long-term missions, including the Voyager space probes launched in 1977.

The weak force—life couldn't exist without it

David Armstrong studies a phenomenon that is ubiquitous in nature, yet only a few non-scientists know what it is.

Bursting bubbles launch bacteria from water to air

Wherever there's water, there's bound to be bubbles floating at the surface. From standing puddles, lakes, and streams, to swimming pools, hot tubs, public fountains, and toilets, bubbles are ubiquitous, indoors and out.

International Team, NASA Make Unexpected Discovery Under Greenland Ice

An international team of researchers, including a NASA glaciologist, has discovered a large meteorite impact crater hiding beneath more than a half-mile of ice in northwest Greenland.

First phase of Brazil's particle accelerator construction completed

Brazil President Michel Temer inaugurated the opening construction phase of a particle accelerator the size of the Maracana football stadium that will be used to make advances in medicine, nutrition, archeology, electronics, energy and the environment.

Quantum science turns social

Researchers developed a versatile remote gaming interface that allowed experts as well as hundreds of citizen scientists all over the world through multiplayer collaboration and in real time to optimize a quantum gas experiment in a lab. Both teams quickly used the interface to dramatically improve upon the previous best solutions, that scientists had established after months of careful optimization. The experiment aims to unravel how humans solve complex, natural science problems.
