New research from Griffith University’s Centre for Quantum Dynamics is broadening perspectives on time and space. Associate Professor Joan Vaccaro challenges the long-held presumption that time evolution — the incessant unfolding of the universe over time — is an elemental part of Nature. She suggests there may be a deeper origin due to a difference between the two directions of time: to the future and to the past.
The United States could slash greenhouse gas emissions from power production by up to 78 percent below 1990 levels within 15 years while meeting increased demand, according to a new study by NOAA and University of Colorado Boulder researchers. The study used a sophisticated mathematical model to evaluate future cost, demand, generation and transmission scenarios.
For 18 months, the organisms were subjected to Mars-like conditions. The atmosphere was 95% carbon dioxide, 1.6% argon, 0.15% oxygen, 2.7% nitrogen, and 370 ppm water, with a pressure of 1,000 pascals. Additionally, they were exposed to ultra-violet radiation similar to that on Mars. And they returned alive.
At a first glance, the globular cluster NGC 1783 looks like a high concentration of pockmarks of light bursting their way through a black expanse. Located roughly 160,000 light-years from the Earth, the massive stellar cluster boasts a mass equivalent to 170,000 suns. The cluster is one of the biggest and brightest located in the Large Magellanic Cloud satellite galaxy.
Companies that are developing self-driving cars of the future want government regulators to clear the road for public access to the technology, once it emerges from current prototype testing.
Inside a massive clean room at NASA's Goddard Space Flight Center in Greenbelt, Maryland the James Webb Space Telescope team is steadily installing the largest space telescope mirror ever. Unlike other space telescope mirrors, this one must be pieced together from segments using a high-precision robotic arm.
Combining experimental investigations and theoretical simulations, researchers have explained why platinum nanoclusters of a specific size range facilitate the hydrogenation reaction used to produce ethane from ethylene.
A new global analysis of seafood found that fish populations throughout the world's oceans are contaminated with industrial and agricultural pollutants, collectively known as persistent organic pollutants (POPs). The study from also uncovered some good news - concentrations of these pollutants have been consistently dropping over the last 30 years.
An average of 30 years had passed since the traumatic events that had left them depressed, anxious, irritable, hypervigilant, unable to sleep well and prone to nightmares. But for 12 people who were involved in a UCLA-led study -- survivors of rape, car accidents, domestic abuse and other traumas -- an unobtrusive patch on the forehead provided considerable relief from post-traumatic stress disorder.
Cable's pricey Internet packages may get some competition from the founder of Aereo, whose first attempt to shake up the cable industry was quashed by the Supreme Court.
A computer program has beaten a human champion at the ancient Chinese board game Go, marking a significant advance for development of artificial intelligence.
A team led by a researcher at the University of California, Riverside has adapted the CRISPR-Cas9 gene editing system for use in a yeast strain that can produce useful lipids and polymers.
Previous treatments for this disease have involved injecting beta cells from dead donors into patients to help their pancreas generate healthy-insulin cells.
Researchers studied the leg lengths of 53 theropod species and devised a formula capable of identifying how well an individual species was adapted for speed.
It's a race befitting the goal of moving passengers and cargo at the speed of sound: Three Southern California companies are building separate test tracks to see how well the "hyperloop" transportation concept works in the real world.
