Human footprints dating back 120,000 years found in Saudi Arabia
Around 120,000 years ago in what is now northern Saudi Arabia, a small band of homo sapiens stopped to drink and forage at a...
Tree planting has potential to increase carbon sequestration capacity
USDA Forest Service scientists have published an in-depth study on the value of tree planting as a means of offsetting carbon emissions in the...
Physicists create turnstile for photons
Physicists from Germany, Denmark, and Austria have succeeded in creating a kind of turnstile for light in glass fibers that allows the light particles...
Marine sponges inspire the next generation of skyscrapers and bridges
When we think about sponges, we tend to think of something soft and squishy. But researchers from the Harvard John A. Paulson School of...
Researchers identify new type of superconductor
Until now, the history of superconducting materials has been a tale of two types: s-wave and d-wave.
Now, Cornell researchers—led by Brad Ramshaw, the Dick...
Astronomers discover an Earth-sized ‘pi planet’ with a 3.14-day orbit
In a delightful alignment of astronomy and mathematics, scientists at MIT and elsewhere have discovered a "pi Earth"—an Earth-sized planet that zips around its...
Rosetta spacecraft detects unexpected ultraviolet aurora at a comet
At Earth, auroras are formed when charged particles from the Sun follow our planet's magnetic field lines to the north and south poles. There, solar particles...
Promising computer simulations for stellarator plasmas
The turbulence model called Gyrokinetic Electromagnetic Numerical Experiment (GENE), developed at Max Planck Institute for Plasma Physics (IPP) at Garching, Germany, has proven to...
Chemists develop ‘smart cells’ with potential to treat illness at cellular...
New research by an international team of chemists describes a new type of artificial cell that can communicate with other cells within the body—with...
Carbon nanotubes developed for super efficient desalination
Membrane separations have become critical to human existence, with no better example than water purification. As water scarcity becomes more common and communities start...
Scientists find a new mechanism for the stabilization of skyrmions
Tiny magnetic whirls that can occur in materials—so-called skyrmions—hold high promises for novel electronic devices or magnetic memory in which they are used as...
