| New mathematical solutions to an old problem in astronomy Posted: 30 Aug 2021 09:32 AM PDT The Bernese theoretical astrophysicist Kevin Heng has achieved a rare feat: On paper, he has derived novel solutions to an old mathematical problem needed to calculate light reflections from planets and moons. Now, data can be interpreted in a simple way to understand planetary atmospheres, for example. The new formulae will likely be incorporated into future textbooks. |
| 'Charging room' system powers lights, phones, laptops without wires Posted: 30 Aug 2021 09:32 AM PDT In a move that could one day free the world's countertops from their snarl of charging cords, researchers have developed a system to safely deliver electricity over the air, potentially turning entire buildings into wireless charging zones. |
| AI helps to spot single diseased cells Posted: 30 Aug 2021 08:33 AM PDT Researchers developed a novel artificial intelligence algorithm for clinical applications called 'scArches'. It efficiently compares patients' cells with a reference atlas of cells of healthy individuals. This enables physicians to pinpoint cells in disease and prioritize them for personalized treatment in each patient. |
| Unease beyond the uncanny valley: How people react to the same faces Posted: 30 Aug 2021 07:49 AM PDT If humanoid robots with the same appearance are mass-produced and become commonplace, how will human beings react to them? In a series of six experiments, scientists examined peoples' reactions when presented with images of people with the same face. Their results reveal a new phenomenon they call the clone devaluation effect -- a greater eeriness associated with cloned faces than with different faces. |
| Can a piece of sticky tape stop computer hackers in their tracks? Posted: 26 Aug 2021 08:17 AM PDT Researchers have taken the fight to online hackers with a giant leap towards realizing affordable, accessible quantum communications, a technology that would effectively prevent the decryption of online activity. Everything from private social media messaging to banking could become more secure due to new technology created with a humble piece of adhesive tape. |
