How plants sense gravity: A new look at the roles of genetics and the cytoskeleton
Gravity affects the ecology and evolution of every living organism. In plants, the general response to gravity is well known: their roots respond positively, growing down, into the soil, and their stems respond ...
New method of measuring the mass of supermassive black holes
(Phys.org)—A new way of measuring the mass of supermassive black holes could revolutionise our understanding of how they form and help to shape galaxies.
NASA sees some powerful 'overshooting cloud tops' in Cyclone Felleng
NASA satellite imagery revealed that Cyclone Felleng is packing some powerful thunderstorms with overshooting cloud tops.
Engineers building hard-working mining robot
(Phys.org)—After decades of designing and operating robots full of scientific gear to study other worlds, NASA is working on a prototype that leaves the delicate instruments at home in exchange for a sturdy ...
US military looks for new life for dead satellites
It's like doing robotic surgery in zero gravity: Imagine scavenging defunct communication satellites for their valuable parts and recycling them to build new ones for cheap.
Nanotech research yields bouncing liquid metal marbles (w/ video)
Coating liquid metal droplets in a nanoparticle mix creates an extra strong non-stick conductive material that retains its shape even under high impact, Australian research has found.
Spacetime: A smoother brew than we knew
Spacetime may be less like foamy quantum beer and more like smooth Einsteinian whiskey, according to research led by physicist Robert Nemiroff of Michigan Technological University being presented today at the 221st American ...
Solar ballet on the Sun
A solar eruption gracefully rose up from the sun on December 31, 2012, twisting and turning.
Masers in stellar nurseries
(Phys.org)—Astronomers have come to realize that the process of star formation, once thought to consist essentially of just the simple coalescence of material by gravity, occurs in a complex series of stages. ...
Shepherd Moon face-off!
Two of Saturn's shepherd moons face off across the icy strand of the F ring in this image, acquired by the Cassini spacecraft on December 18, 2012.
Twin NASA spacecraft deliberately crash into moon
A pair of NASA spacecraft tumbled out of orbit around the moon and crashed back-to-back into the surface on Monday, ending a mission that peered into the lunar interior.
Commercial space travel carries implications for health
(Phys.org)—Just a half-century after the first human ventured into space, commercial space travel—or "space tourism"—is quickly becoming a reality. A new UCSF study looks at the health implications ...
Twin NASA spacecraft to plunge into lunar mountain
NASA's latest moon mission is about to meet its end.
Twin NASA spacecraft prepare to crash into moon
(Phys.org)—Twin lunar-orbiting NASA spacecraft that have allowed scientists to learn more about the internal structure and composition of the moon are being prepared for their controlled descent and impact ...
