| Posted: 18 May 2021 08:47 AM PDT In the insect world, there are rare instances of ants shrugging off their societal duties to become free-loading parasites amongst their free-living relatives. Now, in a new study, an international collaboration of researchers teamed up to discover and collect these rare ant social parasites. Together, they have obtained and analyzed the full DNA genome sequences of three rare 'social parasite' leaf-cutting ant species (called Acromyrmex inquilines) to better understand the differences between them and their respective host species. |
| Study confirms origin of vervet monkeys living near an urban airport for decades Posted: 18 May 2021 08:42 AM PDT Scientists have confirmed the species and origin of a colony of wild African vervet monkeys that landed in Dania Beach more than 70 years ago. They escaped from the Dania Chimpanzee Farm in 1948 and settled in a thick mangrove forest near the Fort Lauderdale-Hollywood International Airport in South Florida. The facility acted as a zoo and also provided primates imported from Africa as research subjects in the development of the polio vaccine and other medical research. |
| Spintronics: Improving electronics with finer spin control Posted: 18 May 2021 08:42 AM PDT Scientists have found a new way to control the alignment state of magnetic atoms in an antiferromagnetic material, showing promise for the development of tiny sensors and memory devices. Researchers now describe their new approach featuring a controllable exchange bias effect, which enables the asymmetric magnetic actions of devices comprised of complex combination structure of different types of magnetic materials. |
| Engineers harvest WiFi signals to power small electronics Posted: 18 May 2021 08:41 AM PDT A research team has developed new technology that uses tiny smart devices known as spin-torque oscillators to harvest and convert wireless radio frequencies into energy to power small electronics. |
| Stunning simulation of stars being born is most realistic ever Posted: 18 May 2021 08:38 AM PDT Astrophysicists has developed the most realistic, highest-resolution 3D simulation of star formation to date. Called STARFORGE (Star Formation in Gaseous Environments), the computational framework is the first to simulate an entire gas cloud -- 100 times more massive than previously possible and full of vibrant colors -- where stars are born. |
| Scientists explore Tesla roads not taken -- and find new potential present-day utility Posted: 17 May 2021 05:36 AM PDT A valve invented by engineer Nikola Tesla a century ago is not only more functional than previously realized, but also has other potential applications today, a team of researchers has found after conducting a series of experiments on replications of the early 20th-century design. |
| Harnessing the hum of fluorescent lights for more efficient computing Posted: 12 May 2021 05:34 AM PDT The property that makes fluorescent lights buzz could power a new generation of more efficient computing devices that store data with magnetic fields, rather than electricity. |
