Astronomers find stream of gas—2.6 million light years long
(Phys.org) —Astronomers and students have found a bridge of atomic hydrogen gas 2.6 million light years long between galaxies 500 million light years away. They detected the gas using the William E. Gordon ...
Computer model simulates Neolithic transition from egalitarianism to leadership and despotism
Planet-like object may have spent its youth as hot as a star
Astronomers have discovered an extremely cool object that could have a particularly diverse history—although it is now as cool as a planet, it may have spent much of its youth as hot as a star.
New tools advance bio-logic: Researchers build more sophisticated synthetic gene circuits
(Phys.org) —Researchers at Rice University and the University of Kansas Medical Center are making genetic circuits that can perform more complex tasks by swapping protein building blocks.
Experts defend operational earthquake forecasting, counter critiques
Experts defend operational earthquake forecasting (OEF) in an editorial published in the Seismological Research Letters (SRL), arguing the importance of public communication as part of a suite of activities intend ...
Going to extremes for enzymes
In the age-old nature versus nurture debate, Douglas Clark, a faculty scientist with Berkeley Lab and the University of California (UC) Berkeley, is not taking sides. In the search for enzymes that can break ...
Synthesis produces new antibiotic: Scientists confirm potent synthesis of natural tetracycline
A fortuitous collaboration at Rice University has led to the total synthesis of a recently discovered natural antibiotic.
Catalytic gold nanoclusters promise rich chemical yields
(Phys.org) —Old thinking was that gold, while good for jewelry, was not of much use for chemists because it is relatively nonreactive. That changed a decade ago when scientists hit a rich vein of discoveries ...
Water leads to chemical that gunks up biofuels production
Trying to understand the chemistry that turns plant material into the same energy-rich gasoline and diesel we put in our vehicles, researchers have discovered that water in the conversion process helps form ...
Moving single cells around—accurately and cheaply
Scientists at the Houston Methodist Research Institute have figured out how to pick up and transfer single cells using a pipette—a common laboratory tool that's been tweaked slightly. They describe this ...
'Shape-shifting' material could help reconstruct faces
Injuries, birth defects (such as cleft palates) or surgery to remove a tumor can create gaps in bone that are too large to heal naturally. And when they occur in the head, face or jaw, these bone defects ...
Tattoo biobatteries produce power from sweat
In the future, working up a sweat by exercising may not only be good for your health, but it could also power your small electronic devices. Researchers will report today that they have designed a sensor ...
Iranian is first woman to win 'Nobel Prize of maths' (Update)
An Iranian-born mathematician has become the first woman to win a prestigious Fields Medal, widely viewed as the Nobel Prize of mathematics.
Ingested nanoparticles may damage liver
(Phys.org) —Nanoparticles in food, sunscreen and other everyday products have many benefits. But Cornell biomedical scientists are finding that at certain doses, the particles might cause human organ damage.
