Imaging space debris in high resolution Posted: 27 Feb 2021 05:33 AM PST Researchers have introduced a new method for taking high-resolution images of fast-moving and rotating objects in space, such as satellites or debris in low Earth orbit. They created an imaging process that first utilizes a novel algorithm to estimate the speed and angle at which an object in space is rotating, then applies those estimates to develop a high-resolution picture of the target. |
When using pyrite to understand Earth's ocean and atmosphere: Think local, not global Posted: 27 Feb 2021 05:33 AM PST Scientists have long used information from sediments at the bottom of the ocean to reconstruct the conditions in oceans of the past. But a study raises concerns about the common use of pyrite sulfur isotopes to reconstruct Earth's evolving oxidation state. These signals aren't the global fingerprint of oxygen in the atmosphere, according to new research from Washington University in St. Louis. |

Signal transduction without signal: Receptor clusters can direct cell movement Posted: 25 Feb 2021 04:09 PM PST Whether we smell, taste or see, or when adrenaline rushes through our veins, all of these signals are received by our cells via a specific group of receptor proteins called G protein-coupled receptors, which transmit signals to the inside of the cell. Biochemists have now discovered that such receptors can also produce signals even in the absence of an external stimulus: For certain receptors clustering is apparently sufficient. |

Nuclear physicists on hunt for squeezed protons Posted: 25 Feb 2021 01:32 PM PST While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights into the particles that build our universe. Now, researchers hunting for these squeezed protons have come up empty-handed, suggesting there's more to the phenomenon than first thought. |
Posted: 25 Feb 2021 01:32 PM PST Born in food web ecology, the concept of trophic levels -- the hierarchy of who eats who in the natural world -- is an elegant way to understand how biomass and energy move through a natural system. It's only natural that the idea found its way into the realm of aquaculture, where marine and freshwater farmers try to maximize their product with efficient inputs. |

Scientists identify cells responsible for liver tissue maintenance and regeneration Posted: 25 Feb 2021 11:39 AM PST While the amazing regenerative power of the liver has been known since ancient times, the cells responsible for maintaining and replenishing the liver have remained a mystery. Now, research has identified the cells responsible for liver maintenance and regeneration while also pinpointing where they reside in the liver. |

64 human genomes as new reference for global genetic diversity Posted: 25 Feb 2021 11:38 AM PST 20 years after the successful completion of the Human Genome Project', an international research group has now sequenced 64 human genomes at high resolution. This reference data includes individuals from around the world, better capturing the genetic diversity of the human species. Among other applications, the work enables population-specific studies on genetic predispositions to human diseases as well as the discovery of more complex forms of genetic variation. |

Post-wildfire landslides becoming more frequent in southern California Posted: 25 Feb 2021 11:38 AM PST Southern California can now expect to see post-wildfire landslides occurring almost every year, with major events expected roughly every ten years, a new study finds. The results show Californians are now facing a double whammy of increased wildfire and landslide risk caused by climate change-induced shifts in the state's wet and dry seasons, according to researchers who mapped landslide vulnerability in the southern half of the state. |

Benefits of team building exercises jeopardized if not truly voluntary Posted: 25 Feb 2021 11:37 AM PST Zoom dress up parties, tug-of-war, 'trust falls' and escape rooms - team building exercises have become the go-to tool for managers trying to increase team rapport and productivity, but unfortunately many employees resent compulsory bonding and often regard these exercises as the bane of their workplace existence. A paper published by Sydney researchers has found participants have mixed feelings about team-building interventions, with the research revealing ethical implications in forcing employees to take part. |
