All heavy elements are created in gigantic supernova explosions. Now scientists are competing to create the world
When biomass is combusted the carbon that once was bound in the growing tree is released into the atmosphere. For this reason, bioenergy is often considered carbon dioxide neutral. Research from Sweden, however, shows that this is a simplification. The use of bioenergy may affect ecosystem carbon stocks, and it can take anything from 2 to 100 years for different biofuels to achieve carbon dioxide neutrality.
A new nanoscale light-emitting diode transmits data at ultrafast rates while using thousands of times less energy than current technologies. It is a major step forward for on-chip data transmission, the researchers say.
CERN has kicked off the High Luminosity LHC (Large Hadron Collider) study with a workshop bringing together scientists and engineers from some 14 European institutions, along with others from Japan and the USA. The goal is to prepare the ground for an LHC luminosity upgrade scheduled for around 2020.
The geological record holds clues that throughout Earth
With European solar markets in decline, the industry is looking to the next hot solar region. Even with political troubles in the U.S., companies still see America as a good long-term bet. (And let
No more cost-effective way to make major cuts in energy use and greenhouse gas emissions exists than retrofitting buildings. Now, from New York to Mumbai to Melbourne, a push is on to overhaul older buildings to make them more energy efficient.
Climate negotiations resume in South Africa today. In the United States, the hot air has yet to stop blowing.
Researchers at the University of Pittsburgh have made advances in better understanding correlated quantum matter that could change technology as we know it, according to a study published in the Nov. 20 edition of <em>Nature</em>.
By 2017, quantum physics will help reduce the energy consumption of our computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue. The next revolution will likely come from tunnel-FET, a technology that takes advantage of a phenomenon referred to as "quantum tunneling."
(PhysOrg.com) -- Researchers from Japan-based semiconductor manufacturer Rohm, together with a team from Osaka University, have come up with a chip that, in experiments, has achieved a wireless data transmission speed of 1.5 gigabits per second. This is a record breaker as the world
Experienced meditators seem to be able switch off areas of the brain associated with daydreaming as well as psychiatric disorders such as autism and schizophrenia, according to a new brain imaging study by Yale researchers.
