| How our body controls inflammation during clean-up mechanisms of damaged cells Posted: 04 Feb 2022 08:34 AM PST A research team has investigated in detail how messenger substances signal inflammation during the removal of damaged cells in the body. Using high-resolution microscopy methods, the researchers were able to show that two proteins interact dynamically with each other and thus determine whether a dying cell triggers an inflammatory reaction in the body. |
| Posted: 04 Feb 2022 06:31 AM PST An 8% increase in summer air conditioning demand can be expected in the U.S. when the global average temperature exceeds 1.5 degrees Celsius above pre-industrial levels. This climate driven increase is likely to cause prolonged blackouts during peak summer heat if states do not expand capacity or improve efficiency, according to a new study of household-level demand. |
| Study looks at glacial lakes, dams in Alaska and potential for flooding Posted: 04 Feb 2022 06:31 AM PST Researchers have produced a detailed inventory of glacial lakes and dams over a 35-year timeframe from 1984 to 2019 in Alaska and northwest Canada. |
| Posted: 04 Feb 2022 05:54 AM PST Beating the bite of mosquitoes this spring and summer could hinge on your attire and your skin. New research indicates that a common mosquito species -- after detecting a telltale gas that we exhale -- flies toward specific colors, including red, orange, black and cyan. The mosquitoes tend to ignore other colors, such as green, purple, blue and white. The researchers believe these findings help explain how mosquitoes find hosts, since human skin, regardless of overall pigmentation, emits a strong red-orange 'signal' to their eyes. |
| Posted: 04 Feb 2022 05:54 AM PST Scientists take a promising step in the direction of developing an HIV vaccine using a unique native-like trimer to develop Tier-2 neutralizing antibodies -- the kind that matter for combating HIV -- in mice. |
| Losing amphibian diversity also means losing poison diversity Posted: 03 Feb 2022 04:25 PM PST Biologists argue that more research needs to be done on the colorful yet poisonous harlequin toads of Central and South America, not only because their ecology is poorly known, but because their toxins are even less studied. Since animal and plant toxins are often inspirations for new drugs, losing the toads through habitat destruction and fungal infections means we lose their poison diversity as well as their genetic diversity. |
| Do bikeshare systems complement or replace public transit? Posted: 03 Feb 2022 03:52 PM PST Bikeshare systems have come a long way since they were first introduced in the Netherlands in the 1960s. They are popular in cities around the world, but how do bike systems affect existing public transportation? |
| How fault lines in a kitchen sink are changing what we know about geology Posted: 03 Feb 2022 01:12 PM PST Researchers unveiled a physical model that yields an unprecedented, high-resolution look at the slip rates of faults, which determine the likelihood of earthquakes. |
| Treasure in tree rings: Using untapped tree ring data to calculate carbon sequestration Posted: 03 Feb 2022 09:30 AM PST Forests around the world have the capacity to pull carbon out of the atmosphere to battle global climate change. But how much carbon they actually absorb is a question that still needs answering, and tree ring data can help, according to a new research synthesis. |
| Supermountains controlled the evolution of life on Earth Posted: 03 Feb 2022 07:30 AM PST Giant mountain ranges at least as high as the Himalayas and stretching up to 8,000 kilometers across entire supercontinents played a crucial role in the evolution of early life on Earth, according to a new study. |
| Balancing sustainability, safety and comfort in engineered floor slabs Posted: 02 Feb 2022 01:59 PM PST Using less material in floors is a viable strategy for improving sustainability in buildings, as it can reduce the structure's environmental footprint. Prioritizing only this goal, however, can lead to unwanted effects -- such as an echo in a room or noise traveling between floors, according to architectural engineers. |
| Interactions between bee gut microbiotas and pesticides Posted: 02 Feb 2022 01:59 PM PST A major review has provided the first field-wide summary of how pesticide exposure affects social bee gut microbiotas and what pesticide-induced disturbances mean for bee hosts. |
| 'Taste' and 'smell' of coral reefs provide insights into a dynamic ecosystem Posted: 02 Feb 2022 01:27 PM PST Hundreds of molecules that are made by important members of the coral reef community were recently discovered by a team of scientists. Together, the compounds--modified amino acids, vitamins and steroids -- comprise the 'smell' or 'taste' of corals and algae in a tropical reef, and will help scientists understand both the food web dynamics and the chemical ecology of these ecosystems. |
