All-terrain microbot moves by tumbling over complex topography
A new type of all-terrain microbot that moves by tumbling could help usher in tiny machines for various applications.
The "microscale magnetic tumbling robot," or...
Tissue paper sensors show promise for health care, entertainment, robotics
University of Washington engineers have turned tissue paper - similar to toilet tissue - into a new kind of wearable sensor that can detect...
Supermassive black hole model predicts characteristic light signals at cusp of...
A new simulation of supermassive black holes—the behemoths at the centers of galaxies—uses a realistic scenario to predict the light signals emitted in the...
Risk of extreme weather events higher if Paris Agreement goals aren’t...
The individual commitments made by parties of the United Nations Paris Agreement are not enough to fulfill the agreement's overall goal of limiting global...
Scientists directly observe electron dynamics of the Northern Lights
The shower of electrons bouncing across Earth's magnetosphere -- commonly known as the Northern Lights -- has been directly observed for the first time...
Breaking local symmetry—why water freezes but silica forms a glass
Everyone knows that water freezes at 0 degrees C. Life on Earth would be vastly different if this were not so. However, water's cousin,...
Running helps the brain counteract negative effect of stress
Most people agree that getting a little exercise helps when dealing with stress. A new BYU study discovers exercise—particularly running—while under stress also helps...
Researchers successfully reverse Alzheimer’s disease in mouse model
A team of researchers from the Cleveland Clinic Lerner Research Institute have found that gradually depleting an enzyme called BACE1 completely reverses the formation...
Rotating dusty gaseous donut around an active supermassive black hole
Almost all galaxies hold concealed monstrous black holes in their centers. Researchers have known for a long time that the more massive the galaxy...
Better together: Silicon qubits plus light add up to new quantum...
A silicon-based quantum computing device could be closer than ever due to a new experimental device that demonstrates the potential to use light as...
Cells ‘walk’ on liquids a bit like geckos
Researchers at Queen Mary University of London have discovered that cells can 'walk' on liquids a bit like the way geckos stick to other...
