Engineers create nanophotonic structures that can compute using “light and waves”
Analog computing might get a new lease on life thanks to metamaterials that control electromagnetic waves. Researchers from the University of Pennsylvania (UPenn) developed a metamaterial whose tiny structures manipulate light to solve mathematical equations. “Photonic calculus” encodes parameters into the properties of an electromagnetic wave. Once the wave passes through the metamaterial, its properties get altered by nanostructures. The modified electromagnetic wave serves […]

Scientists explain how the brain’s “inner pickpocket” identifies objects
How do skilled pickpockets figure out an object with just the slightest touch? A study from the University of Cambridge and Columbia University revealed that the brain can identify an object’s properties using purely statistical information. In sum, everyone has an “inner pickpocket” lurking inside them. This interesting finding not only explains why this form of thievery […]

This updated jumping robot can be used to develop smaller robots for aid-and-rescue missions, suggest scientists
Salto is a robot that stands less than a foot tall, but it jumps more than three times its height. Its small size even lets it pass through cramped spaces to reach people trapped under rubble. Developed by a team from the University of California (UC), Berkeley in 2016, Salto’s capabilities have grown in leaps and bounds over the […]

NASA designs suits to help astronauts deal with microbes in Martian dust (while still denying discovery of microbial life on Mars)
Researchers have not yet determined if even the most simplistic form of alien life exists on Mars. But just in case, NASA is designing spacesuits that will keep astronauts safe from both potential Martian microbes and actual dust. The crews of the first three Apollo missions that landed on the moon went through quarantine protocol […]

Study: Light and nanotech can prevent bacterial infections caused by medical implant surgeries
Spanish researchers combined nanotechnology and photonics to improve the effectiveness of medical meshes in surgical implants. Powered by light, nanoparticles killed any disease-causing bacteria that might cause a dangerous infection in the mesh. Medical meshes help a surgery patient recover faster after an operation that removed, repaired or replaced damaged tissue in his body. A […]

NASA’s Star Wars-inspired Astrobee will assist astronauts, boost productivity and maintain spacecraft
NASA’s newest robots called Astrobee resemble cubes far more than bees. But the American space agency believes that the autonomous flying robots will prove as busy as their insect namesake. On Earth, bees enjoy a reputation for working hard and nonstop. Their robotic, space-going counterparts will share those qualities by supporting human astronauts in space and […]

Loving their children on a cellular level: Egg cells “choose” healthy cell components to pass to the next generation
Mothers really do want only the best for their kids. In a recent study published in Nature, researchers found that a developing ovum tests each mitochondrion, and selects only the healthiest to be passed to the next generation. A mitochondrion is an organelle that converts food into energy and drives cellular activity. Often referred to in […]

Treating drug-resistant Candida albicans with 2 natural molecules
Lung moss (Lobaria pulmonaria) contains plant-based compounds with antibiotic and anti-fungal properties. A study from the Shandong University (SDU) tested their efficacy on drug-resistant Candida albicans to identify the most active molecules. The researchers received funding from the National Natural Science Foundation and the SDU’s Young Scholars Program. They published their findings in the Chinese […]

Understanding how resurrection plants control their water structure to survive long periods of drought
Resurrection plants possess the ability to survive for months or years of drought before making a full recovery once water becomes available again. Japanese and Bulgarian researchers learned how one such species pulled it off by comparing it with a non-resurrecting relative. Their findings showed that the Orpheus flower (Haberlea rhodopensis) got ready for dry […]

Deaf after a loud concert? Researchers explain why
Most people know that listening to loud sounds will temporarily disrupt their hearing. Swedish researchers can now tell us how that happens — they identified the specific part of the hearing organ affected by sounds. “We have discovered that a tiny structure in the cochlea known as the tectorial membrane plays an important role in this […]
