Climate change is in full swing and will continue unabated as long as we do not succeed in significantly reducing CO2 emissions. For this we need all the options. One idea is to return the greenhouse gas CO2...

Speed limits apply not only to traffic. There are limitations on the control of light as well, in optical switches for internet traffic, for example. Physicists at Chalmers University of Technology now understand why it is not possible...

Lithium metal batteries hold tremendous promise for next-generation energy storage because the lithium metal negative electrode has 10 times more theoretical specific capacity than the graphite electrode used in commercial Li-ion batteries. It also has the most negative...

Most of the plastic objects we see are created using injection molding, but designing such molds is a difficult task, usually requiring experts. Now, computer scientists from the Institute of Science and Technology Austria (IST Austria), the University...

The dust that coats much of the surface of Mars originates largely from a single thousand-kilometer-long geological formation near the Red Planet's equator, scientists have found. A study published in the journal Nature Communications found a chemical match between...

Keyboards touch our everyday lives yet, despite the well-known drawbacks of current layouts used across the globe, the position of characters has largely remained the same. Researchers at Aalto University, as part of an international collaboration, have now...

University of Colorado Boulder and University of Wyoming engineers have successfully scaled up an innovative water-cooling system capable of providing continuous day-and-night radiative cooling for structures. The advance could increase the efficiency of power generation plants in summer...

A material based on a natural product of bones and citrus fruit, called citrate, provides the extra energy that stem cells need to form new bone tissue, according to a team of Penn State bioengineers. Their new understanding...

A team of Nottingham scientists is using drones to survey woody climbing plants and better understand how they may affect the carbon balance of tropical rainforests. The findings of the study -- 'A view from above: Unmanned Aerial Vehicles...

NASA's MarCO mission was designed to find out if briefcase-sized spacecraft called CubeSats could survive the journey to deep space. Now, MarCO -- which stands for Mars Cube One -- has Mars in sight. One of the twin MarCO...
