| This touchy-feely glove senses and maps tactile stimuli Posted: 05 Aug 2021 03:06 PM PDT A new tactile glove could help regain motor function after stroke and enhance virtual gaming experiences. |
| All in your head: Exploring human-body communications with binaural hearing aids Posted: 05 Aug 2021 12:06 PM PDT Wearable technology seems all poised to take over next-generation electronics, yet most wireless communication techniques are not up to the task. To tackle this issue, scientists have delved deep into human-body communications, in which human tissue is used as the transmission medium for electromagnetic signals. Their findings pave the way to more efficient and safer head-worn devices, such as binaural hearing aids and earphones. |
| Lunar samples solve mystery of the moon's supposed magnetic shield Posted: 05 Aug 2021 11:11 AM PDT Tests of glass samples gathered on Apollo missions show magnetization may result from impacts of objects like meteors, not as a result of magnetization from the presence of a magnetic shield. |
| Quantum crystal could be a new dark matter sensor Posted: 05 Aug 2021 11:11 AM PDT Physicists have linked together, or 'entangled,' the mechanical motion and electronic properties of a tiny blue crystal, giving it a quantum edge in measuring electric fields with record sensitivity that may enhance understanding of the universe. |
| Leaping squirrels! Parkour is one of their many feats of agility Posted: 05 Aug 2021 11:11 AM PDT Biologists tested free-ranging squirrels to determine how quickly they adapt to the bendiness of their launching branch in order to successfully land. The squirrels learned within a few trials to leap no matter how bendy, but have a failsafe to stick the landing: claws. They also innovated, bounding off vertical surfaces to extend their range, just as parkouring humans. Incorporating such control could improve robot agility. |
| Scientists mail freeze-dried mouse sperm on a postcard Posted: 05 Aug 2021 08:54 AM PDT Scientists no longer have to worry about their bottles of mouse sperm breaking in transit. Researchers have developed a way to freeze dry sperm on a plastic sheet in weighing paper so that samples can withstand being mailed via postcard. This method allows for mouse sperm to be transported easily, inexpensively, and without the risk of glass cases breaking. |
| New method opens the door to efficient genome writing in bacteria Posted: 05 Aug 2021 08:54 AM PDT Biological engineers have devised a way to program memories into bacterial cells by rewriting their DNA. The new DNA writing technique, which the researchers call HiSCRIBE, is much more efficient than previously developed systems for editing DNA in bacteria. |
| Microwave-powered rocket propulsion gets a boost Posted: 03 Aug 2021 07:55 AM PDT Researchers found that power could be sent to a free-flying drone via a beam of microwave radiation. The team estimated the efficiency of this process and compared it with that for a fixed-position drone. The results have implications for the possibility of using such microwave power transmission to launch aircraft, spacecraft, and rockets and avoid the high onboard-fuel requirements of commonly used propulsion approaches. |
| Giraffes are as socially complex as elephants, study finds Posted: 03 Aug 2021 05:49 AM PDT Scientists have discovered evidence that giraffes are a highly socially complex species. |
