Researchers find it would require 2.4 times less energy to create a black hole than thought
Hyper and micro-gravity affect processes involved in reproduction, brain diseases and cancer, new study shows
University of Montreal researchers found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular "highways" that ensure the growth and functionality ...
Cassini returns images of battered Saturn Moon
(Phys.org) —Following its last close flyby of Saturn's moon Rhea, NASA's Cassini spacecraft captured these raw, unprocessed images of the battered icy moon. They show an ancient, cratered surface bearing ...
Black hole simulations on XSEDE supercomputers present new view of jets and accretion disks
Voracious absences at the center of galaxies, black holes shape the growth and death of the stars around them through their powerful gravitational pull and explosive ejections of energy.
MOND used to predict key property in Andromeda's satellites
Using modified laws of gravity, researchers from Case Western Reserve University and Weizmann Institute of Science closely predicted a key property measured in faint dwarf galaxies that are satellites of the nearby giant ...
Researchers find soap film micro-channel size tunable with electric charge
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.
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.
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. ...
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.
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 ...
