| Asthma may reduce risk of brain tumors -- but how? Posted: 10 Dec 2021 12:50 PM PST Asthma has been associated with a lowered risk of brain tumors, and researchers now think they know why: Immune cells activated under conditions of asthma are less able to promote the growth of brain tumors. The findings could lead to new therapeutic approaches. |
| 'Human-like' brain helps robot out of a maze Posted: 10 Dec 2021 11:07 AM PST A maze is a popular device among psychologists to assess the learning capacity of mice or rats. But how about robots? Can they learn to successfully navigate the twists and turns of a labyrinth? Now, researchers have demonstrated they can. Their robot bases its decisions on the very system humans use to think and act: the brain. The study paves the way to exciting new applications of neuromorphic devices in health and beyond. |

| New understanding of plant nutrient response could improve fertilizer management strategies Posted: 10 Dec 2021 09:18 AM PST Green is a color that is almost universally associated with plants -- for good reason. The green pigment chlorophyll is essential to plants' ability to generate food; but what happens if they don't have enough of it? New work reveals the complex, interdependent nutrient responses underpinning a potentially deadly, low-chlorophyll state called chlorosis that's associated with an anemic, yellow appearance. It could usher in more environmentally friendly agricultural practices -- using less fertilizer and fewer water resources. |
| Seasonal temperature impacts patient lab results Posted: 10 Dec 2021 08:30 AM PST Ambient temperature influences the results of some of the most used laboratory tests, and these distortions likely affect medical decision making, such as whether to prescribe medications, researchers report. The authors say that laboratories could statistically adjust for ambient temperature on test days when reporting lab results to account for day-to-day variability. |
| Scientists identify malfunctioning brain cells as potential target for Alzheimer's treatment Posted: 10 Dec 2021 08:30 AM PST Scientists have identified a rare population of potentially toxic senescent cells in human brains that can serve as a target for a new Alzheimer's disease treatment. |
| Dinosaurs’ last spring: Study pinpoints timing of Chicxulub asteroid impact Posted: 10 Dec 2021 07:31 AM PST Scientists conclusively confirm the time year of the catastrophic Chicxulub asteroid, responsible for the extinction of dinosaurs and 75 percent of life on Earth 66 million years ago. Springtime, the season of new beginnings, ended the 165-million-year reign of dinosaurs and changed the course of evolution on Earth. |
| An easy relationship between a beetle and its yeast symbiont Posted: 10 Dec 2021 07:31 AM PST Lizard beetles farm yeast inside bamboo stems for their developing larvae to eat. Scientists have now found that, contrary to other insect-fungus relationships, the job of the yeast in this one does not involve digesting the complex sugars in bamboo's woody tissues for its host. |

| New phenomenon: Forest mammals eavesdrop on messy monkeys Posted: 10 Dec 2021 07:31 AM PST Researchers have discovered a unique phenomenon among forest mammals -- eavesdropping. Their study demonstrates that various animal species depend on one another in more ways than ever imagined when it comes to finding food. Consequently, one species' disappearance from a habitat can have major consequences. |
| Dinosaurs and amber: A new window to the Cretaceous world from 110 million years ago Posted: 10 Dec 2021 07:31 AM PST New findings of amber in the site of Ariño in Teruel (Spain) have enabled the reconstruction of a swampy paleoenvironment with a rich coastal resin forest from 110 million years ago, from the era of dinosaurs. This place featured conifers and understories of gymnosperms and ferns, and flower plants, where insects, turtles, crocodiles, mammals and dinosaurs such as the species Proa valdearinnoensis and Europelta carbonensis lived. |

This combined unit is able to perform atomic resolution observation at an energy resolution of 0.2 eV -- the highest resolution ever recorded for non-monochromatic electron guns -- with a high current stability of 0.4%. |
| Atom laser creates reflective patterns similar to light Posted: 10 Dec 2021 06:30 AM PST Cooled to almost absolute zero, atoms not only move in waves like light but also can be focused into shapes called caustics, similar to the reflecting or refracting patterns light makes on the bottom of a swimming pool or through a curved wine glass. In experiments, scientists have developed a technique to see these matter wave caustics by placing attractive or repulsive obstacles in the path of a cold atom laser. The results are curving cusps or folds, upward or downward 'V' shapes. These caustics have potential applications for highly precise measurement or timing devices such as interferometers and atomic clocks. |

The study concluded that there is still substantial room to increase rice production while reducing the negative environmental impacts. A leading agronomist describes the study as 'the most comprehensive global evaluation of production systems for a major staple crop, (one that) will set the standard for future global comparison.' |
| Mini-jet found near Milky Way's supermassive black hole Posted: 09 Dec 2021 05:16 PM PST Our Milky Way's central black hole has a leak. This supermassive black hole looks like it still has the vestiges of a blowtorch-like jet dating back several thousand years. NASA's Hubble Space Telescope hasn't photographed the phantom jet but has helped find circumstantial evidence that it is still pushing feebly into a huge hydrogen cloud and then splattering, like the narrow stream from a hose aimed into a pile of sand. |
