| Scientist advances prospect of regeneration in humans Posted: 17 Nov 2021 06:16 PM PST In a study that builds on earlier research that identified macrophages as essential to regeneration in the axolotl, a highly regenerative salamander, a scientist has identified the source of these critical white blood cells as the liver. By giving scientists a place to look for pro-regenerative macrophages in humans, the discovery brings science a step closer to the ability to regenerate tissues and organs lost to injury or disease. |
| Shape-morphing microrobots deliver drugs to cancer cells Posted: 17 Nov 2021 07:38 AM PST Chemotherapy successfully treats many forms of cancer, but the side effects can wreak havoc on the rest of the body. Delivering drugs directly to cancer cells could help reduce these unpleasant symptoms. Now, in a proof-of-concept study, researchers have made fish-shaped microrobots that are guided with magnets to cancer cells, where a pH change triggers them to open their mouths and release their chemotherapy cargo. |
| Perceptual links between sound and shape may unlock origins of spoken words Posted: 17 Nov 2021 07:01 AM PST Most people around the world agree that the made-up word 'bouba' sounds round in shape, and the made-up word 'kiki' sounds pointy -- a discovery that may help to explain how spoken languages develop, according to a new study. Language scientists have discovered that this effect exists independently of the language that a person speaks or the writing system that they use, and it could be a clue to the origins of spoken words. |
| New holographic camera sees the unseen with high precision Posted: 17 Nov 2021 07:01 AM PST Northwestern University researchers have invented a new high-resolution camera that can see the unseen -- including around corners and through scattering media, such as skin, fog or potentially even the human skull. |
| `Oh, snap!’ A record-breaking motion at our fingertips Posted: 16 Nov 2021 05:15 PM PST Researchers studied the physics of a finger snap and determined how friction plays a critical role. Using an intermediate amount of friction, not too high and not too low, a snap of the finger produces the highest rotational accelerations observed in humans, even faster than the arm of a professional baseball pitcher. |
| Life on Mars search could be misled by false fossils, study says Posted: 16 Nov 2021 05:15 PM PST Mars explorers searching for signs of ancient life could be fooled by fossil-like specimens created by chemical processes, research suggests. |
