Accelerating universe? Not so fast
A University of Arizona-led team of astronomers found that the type of supernovae commonly used to measure distances in the universe fall into distinct populations not recognized before; the findings have ...
Magnetic-field detector is 1,000 times more efficient than its predecessors
MIT researchers have developed a new, ultrasensitive magnetic-field detector that is 1,000 times more energy-efficient than its predecessors. It could lead to miniaturized, battery-powered devices for medical ...
Researchers improve efficiency of human walking (w/ video) (Update)
Humans have evolved to be incredibly efficient at walking. In fact, simulations of human locomotion show that walking on level ground and at a steady speed should theoretically require no power input at all.
Festo has BionicANTs communicating by the rules for tasks
Astronomers identify the best supernovae for measuring cosmic distances
The brilliant explosions of dead stars have been used for years to illuminate the far-flung reaches of our cosmos. The explosions, called Type Ia supernovae, allow astronomers to measure the distances to ...
New dwarf galaxies discovered in orbit around the Milky Way
A team of astronomers from the University of Cambridge have identified nine new dwarf satellites orbiting the Milky Way, the largest number ever discovered at once. The findings, from newly-released imaging ...
Best of Last Week – First photo of light as particle/wave, the dark side of cosmology and a hormone that mimics exercise
The dark side of cosmology
It's a beautiful theory: the standard model of cosmology describes the universe using just six parameters. But it is also strange. The model predicts that dark matter and dark energy – two mysterious entities ...
Why seashells' mineral forms differently in seawater
For almost a century, scientists have been puzzled by a process that is crucial to much of the life in Earth's oceans: Why does calcium carbonate, the tough material of seashells and corals, sometimes take ...
