Tissue Chips Rocket to International Space Station

Dec. 5, 2018 — Scientists have recently sent tissue chips, a research technology that reflects the human body, into space. On Dec. 4, the first set of NIH-funded tissue chips that model aspects of the human immune ... read more

Odd Bodies, Rapid Spins Keep Cosmic Rings Close

Nov. 19, 2018 — Forget those shepherding moons. Gravity and the odd shapes of asteroid Chariklo and dwarf planet Haumea -- small objects deep in our solar system -- can be credited for forming and maintaining their ... read more

Nov. 16, 2018 — Today, most of the water on Mars is locked away in frozen ice caps. But billions of years ago it flowed freely across the surface, forming rushing rivers that emptied into craters, forming lakes and ... read more

Nov. 15, 2018 — It's not every day you get to observe a gamma-ray binary system. In fact, it's a once-in-a-lifetime experience comparable to seeing Halley's Comet or a solar ... read more

Nov. 15, 2018 — Researchers 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 ... read more

Nov. 15, 2018 — The first known interstellar object to visit our solar system -- named 'Oumuamua -- was detected in October 2017 by Hawaii's Pan-STARRS 1 telescope. But it was too faint for NASA's ... read more

Nov. 15, 2018 — A close study of auroras has revealed new ways of understanding the physics of explosive energy releases in ... read more

Nov. 14, 2018 — An international team has discovered a 31-km wide meteorite impact crater buried beneath the ice-sheet in the northern Greenland. This is the first time that a crater of any size has been found under ... read more

Gravitational Waves from a Merged Hyper-Massive Neutron Star

Nov. 14, 2018 — For the first time astronomers have detected gravitational waves from a merged, hyper-massive neutron ... read more

Nov. 14, 2018 — In 2011, researchers proposed that artificial guide stars could be used to measure the Earth's magnetic field in the mesosphere. An international group of scientists has recently managed to do ... read more

Nov. 8, 2018 — Scientists have demonstrated for the first time that heat from the sun and coldness from outer space can be collected simultaneously with a single device. Their research suggests that devices for ... read more

Nov. 7, 2018 — Earth's water may have originated from both asteroidal material and gas left over from the formation of the Sun, according to new research. The new finding could give scientists important ... read more

Nov. 5, 2018 — If extraterrestrial intelligence exists somewhere in our galaxy, a new study proposes that laser technology on Earth could, in principle, be fashioned into something of a planetary porch light -- a ... read more

Magnetic Pumping Pushes Plasma Particles to High Energies

Nov. 5, 2018 — The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it ... read more

Electrically Charged Dust in Microgravity Is Surprisingly Orderly

Nov. 5, 2018 — In a lab on Earth, electrically charged dust generally lines up either along the downward pull of gravity or across it. Scientists got a surprise when examining data from a similar experiment on the ... read more

A Stellar Achievement: Magnetized Space Winds in the Laboratory

Nov. 5, 2018 — New insights have been gained about stellar winds, streams of high-speed charged particles called plasma that blow through interstellar space. These winds, created by eruptions from stars or stellar ... read more

Nov. 5, 2018 — The presence of water on Mars has been theorized for centuries. Early telescopes revealed ice caps, and early astronomers noted channels that were hypothesized to be natural rivers or ... read more

Nov. 2, 2018 — Combined observations of Comet McNaught -- one of the brightest comets visible from Earth in the past 50 years -- have revealed new insights on the nature of comets and their relationship with the ... read more

Nov. 2, 2018 — NASA's Dawn spacecraft has gone silent, ending a historic mission that studied time capsules from the solar system's earliest ... read more

Oct. 31, 2018 — Mars' organic carbon may have originated from a series of electrochemical reactions between briny liquids and volcanic minerals, according to analyses of three Martian meteorites. The discovery ... read more
