| President Biden reveals first image from NASA's Webb Telescope Posted: 11 Jul 2022 04:47 PM PDT The first full-color image from NASA's James Webb Space Telescope reveals thousands of galaxies, including the faintest objects ever observed in the infrared. |
| Could a computer diagnose Alzheimer's disease and dementia? Posted: 11 Jul 2022 01:32 PM PDT Researchers have developed a new tool that could automate the process of diagnosing Alzheimer's disease and eventually allow it to move online. |
| Flashing creates hard-to-get 2D boron nitride Posted: 11 Jul 2022 01:32 PM PDT Chemists use their flash Joule heating process to synthesize 2D flakes of boron nitride and boron carbon nitride, highly valued for lending thermal and chemical stability to compounds. |
| Soft but tough: Biohybrid material performs like cartilage Posted: 11 Jul 2022 01:31 PM PDT Producing biomaterials that match the performance of cartilage and tendons has been an elusive goal for scientists, but a new material demonstrates a promising new approach to mimicking natural tissue. |
| X-rays help researchers piece together treasured cellular gateway Posted: 11 Jul 2022 01:31 PM PDT After almost two decades of synchrotron experiments, scientists have captured a clear picture of a cell's nuclear pores, which are the doors and windows through which critical material in your body flows in and out of the cell's nucleus. These findings could lead to new treatments of certain cancers, autoimmune diseases and heart conditions. |
| The ultimate fate of a star shredded by a black hole Posted: 11 Jul 2022 11:32 AM PDT In 2019, astronomers observed the nearest example to date of a star that was shredded, or 'spaghettified,' after approaching too close to a massive black hole. That tidal disruption of a sun-like star by a black hole 1 million times more massive than itself took place 215 million light years from Earth. Luckily, this was the first such event bright enough that astronomers could study the optical light from the stellar death, specifically the light's polarization, to learn more about what happened after the star was torn apart. |
| Video game players show enhanced brain activity, decision-making skill study Posted: 11 Jul 2022 10:53 AM PDT Frequent players of video games show superior sensorimotor decision-making skills and enhanced activity in key regions of the brain as compared to non-players, according to a recent study. |
| Hopping space dust makes asteroids look rougher Posted: 11 Jul 2022 10:50 AM PDT When NASA's OSIRIS-REx spacecraft arrived at the asteroid Bennu, scientists discovered something surprising: The asteroid's surface wasn't smooth like many were expecting but was covered in large boulders. Now, a team of physicists think they know why. |
| Nanoparticles can save historic buildings Posted: 11 Jul 2022 06:51 AM PDT Buildings made of porous rock can weather over the years. Now scientists have studied in detail how silicate nanoparticles can help save them. Many historical buildings were built of sandstone. It is easy to work with, but does not withstand weathering well. It consists of sand grains that are relatively weakly bonded to each other. However, it is possible to increase the resistance of the stone by treating it with special silicate nanoparticles. |
