Physicists solve 50-year lightning mystery – why does it zigzag and what does it have to do with thunder

[…] For the past 50 years, scientists around the world have debated why lightning zig-zags and how it is connected to the thunder cloud above. There hasn’t been a definitive explanation until now, with a University of South Australia plasma physicist publishing a landmark paper that solves both mysteries. […] The answer? Singlet-delta metastable oxygen Read more about Physicists solve 50-year lightning mystery – why does it zigzag and what does it have to do with thunder[…]

Swarming bees generate so much electricity they may potentially change the weather

[…] The finding, which researchers made by measuring the electrical fields around honeybee (apis mellifera) hives, reveals that bees can produce as much atmospheric electricity as a thunderstorm. This can play an important role in steering dust to shape unpredictable weather patterns; and their impact may even need to be included in future climate models. Read more about Swarming bees generate so much electricity they may potentially change the weather[…]

Scientists grow human brain cells to play Pong

Led by Brett Kagan, chief scientific officer at Cortical Labs, the researchers showed that by integrating neurons into digital systems they could harness “the inherent adaptive computation Read more about Scientists grow human brain cells to play Pong[…]

Researchers detect the first definitive proof of elusive sea level fingerprints

When ice sheets melt, something strange and highly counterintuitive happens to sea levels. It works basically like a seesaw. In the area close to where theses masses of glacial ice melt, ocean levels fall. Yet thousands of miles away, they actually rise. It largely happens because of the loss of a gravitational pull toward the Read more about Researchers detect the first definitive proof of elusive sea level fingerprints[…]

Tiny swimming robots treat deadly pneumonia in mice

Nanoengineers at the University of California San Diego have developed microscopic robots, called microrobots, that can swim around in the lungs, deliver medication and be used to clear up life-threatening cases of bacterial pneumonia. In mice, the microrobots safely eliminated pneumonia-causing bacteria in the lungs and resulted in 100% survival. By contrast, untreated mice all Read more about Tiny swimming robots treat deadly pneumonia in mice[…]

Air pollution cancer breakthrough rewrites how to think about cancer activation

Researchers say they have cracked how air pollution leads to cancer, in a discovery that completely transforms our understanding of how tumours arise. The team at the Francis Crick Institute in London showed that rather than causing damage, air pollution was waking up old damaged cells. One of the world’s leading experts, Prof Charles Swanton, Read more about Air pollution cancer breakthrough rewrites how to think about cancer activation[…]

How to Easily Make Your Own Pyramid Salt Crystals

[…] What is pyramid salt? Pyramid salt crystals are made of the same stuff as regular salt. But these crystals look different because they formed in a different way. In nature, these elusive crystals grow on the surface of quiet, undisturbed pools of salt water that evaporate under the hot sun.

Physicists invent intelligent quantum sensor of light wave properties

[…] Typically, when you want to characterize a wave of light, you have to use different instruments to gather information, such as the intensity, wavelength and polarization state of the light. Those instruments are bulky and can occupy a significant area on an optical table,” said Dr. Fan Zhang, a corresponding author of the study Read more about Physicists invent intelligent quantum sensor of light wave properties[…]
