In a finding that could benefit drone design, award-winning research by a doctoral student at The University of Alabama in Huntsville (UAH) shows that the undulating flight paths of monarch butterflies are actually more energy efficient than a straight-line path.

Google has cornered the market on making high-resolution, aerial imagery of earth's most breathtaking landscapes available to the public.

Researchers in robotic materials aim to artificially control animal locomotion to address the existing challenges to actuation, control and power requirements in soft robotics. In a new report in Science Advances, Nicole W. Xu and John O. Dabiri at the departments of bioengineering, civil and environmental engineering and mechanical engineering at the Stanford University presented a biohybrid robot that used onboard microelectronics to induce swimming in live jellyfish. They measured the ability to substantially enhance propulsion by driving body contractions at an optimal frequency range faster than natural behavior. The manoeuvre increased swimming speed by nearly threefold, although with only a twofold increase in metabolic expenditure of the animal and 10 mW of external power input to the microelectronics. The biohybrid robot used 10 to 1000 times less external power per mass than with previously reported aquatic robots. The capability can improve the performance scope of biohybrid robots relative to native performance, with potential applications as biohybrid ocean monitoring robots.

Mac computers are less secure than they used to be and more vulnerable to certain types of software threats than their Microsoft Windows counterparts.

An artificial neural network can reveal patterns in huge amounts of gene expression data and discover groups of disease-related genes. This has been shown by a new study led by researchers at Linköping University, published in Nature Communications. The scientists hope that the method can eventually be applied within precision medicine and individualized treatment.

For some infants, a wet diaper is cause for an instant, vociferous demand to be changed, while other babies may be unfazed and happy to haul around the damp cargo for lengthy periods without complaint. But if worn too long, a wet diaper can cause painful rashes, and miserable babies—and parents.

It's being called nasty—oh, the reinfection of it all— and sneaky for good reason: It's all of that, known to headache-watchers as xHelper, which turns out to be of no help at all once infected. The malware xHelper was identified as a trojan dropper.

Asian plane makers have thrown huge sums at building jets but flagship projects have suffered repeated setbacks, and they face a tough time breaking into a market dominated by established players.

The California Supreme Court ruled on Thursday that Apple must pay employees for time spent waiting for their bags and personal electronic devices to be searched when they leave work.

The new coronavirus outbreak could mean a $4-5 billion drop in worldwide airline revenue, the International Civil Aviation Organization said on Thursday.

Facebook founder and CEO Mark Zuckerberg on Friday backed moves by the OECD group of free-market economies to reform the way online giants are taxed worldwide, even if that means companies like his own paying more to national governments.

In 1989, a young scholar named Francis Fukuyama published an essay with the provocative title “The End of History?” in the National Interest. He argued that, with the fall of the Soviet Union, hist…

Instead of accepting that life is cyclical, and that bad times are normal, we expect that we should always be on an upward cycle. That causes frustration.
