| Solid aerosols found in Arctic atmosphere could impact cloud formation and climate Posted: 28 Mar 2022 01:53 PM PDT Solid aerosols can change how clouds form in the Arctic. And, as the Arctic loses ice, researchers expect to see more of these unique particles formed from oceanic emissions combined with ammonia from birds, which will impact cloud formation and climate. Additionally, understanding the characteristics of aerosols in the atmosphere is critical for improving the ability of climate models to predict current and future climate in the Arctic and beyond. |
| Lack of sleep increases unhealthy abdominal fat, study finds Posted: 28 Mar 2022 01:53 PM PDT New research shows that lack of sufficient sleep combined with free access to food increases calorie consumption and consequently fat accumulation, especially unhealthy fat inside the belly. |
| Caribou herd rebounds as Indigenous stewards lead conservation efforts Posted: 28 Mar 2022 01:06 PM PDT Despite recovery efforts from federal and provincial governments, caribou populations across Canada continue to decline, largely due to human activity. But as a new study finds, in central British Columbia there is one herd of mountain caribou, the Klinse-Za, whose numbers are going in the opposite direction -- all thanks to a collaborative recovery effort led by West Moberly First Nations and Saulteau First Nations. |
| New information about amyloid filaments in neurodegenerative diseases Posted: 28 Mar 2022 01:06 PM PDT Researchers have helped identify that a common protein found in neurodegenerative diseases forms amyloid filaments in an age-dependent manner without a connection to disease. |
| Scientists observe mysterious death of a star emitting six rings Posted: 28 Mar 2022 12:39 PM PDT Astrophysicists studying in unprecedented detail a red giant star named V Hydrae have witnessed the star's mysterious death throes. Researchers discovered that the carbon-rich star has expelled six slowly expanding molecular rings and two hourglass-shaped structures ejecting matter out into space at high speeds. |
| Hundreds of new mammal species waiting to be found, study says Posted: 28 Mar 2022 12:05 PM PDT At least hundreds of so-far unidentified species of mammals are hiding in plain sight around the world, a new study suggests. Researchers found that most of these hidden mammals are small bodied, many of them bats, rodents, shrews, and moles. |
| Genetic risk for asthma comes from changes in airway cells, study finds Posted: 28 Mar 2022 10:36 AM PDT A significant amount of genetic risk for asthma is likely mediated through altered gene expression within the airway epithelium. That is the conclusion of a new study to identify genetic variants that cause asthma by altering the function of airway cells. |
| How cells control their borders Posted: 28 Mar 2022 08:24 AM PDT Bacteria and yeast need to prevent leakage of numerous small molecules through their cell membrane. Biochemists have studied how the composition of the membrane affects passive diffusion and the robustness of this membrane. Their results could help the biotech industry to optimize microbial production of useful molecules and help in drug design. |
| Posted: 28 Mar 2022 08:23 AM PDT A new study shows highly creative people's brains appear to work differently than others, with an atypical approach that makes distant connections more quickly by bypassing the 'hubs' seen in non-creative brains. |
| Solar energy explains fast yearly retreat of Antarctica's sea ice Posted: 28 Mar 2022 08:23 AM PDT Sea ice around Antarctica retreats more quickly than it advances, an asymmetry that has been a puzzle. New analysis shows that the Southern Hemisphere is following simple rules of physics, as peak midsummer sun causes rapid changes. In this respect, it seems, it's Arctic sea ice that is more mysterious. |
| Smells like ancient society: Scientists find ways to study and reconstruct past scents Posted: 28 Mar 2022 08:21 AM PDT In a new paper, researchers discuss the importance of scent in human history and address how and why experts might investigate smells from the past. |
| New technology could make biopsies a thing of the past Posted: 28 Mar 2022 08:21 AM PDT Researchers have developed a technology that could replace conventional biopsies and histology with real-time imaging within the living body. MediSCAPE is a high-speed 3D microscope capable of capturing images of tissue structures that could guide surgeons to navigate tumors and their boundaries without needing to remove tissues and wait for pathology results. |
| Atlas of migraine cell types sheds light on new therapeutic targets Posted: 28 Mar 2022 08:21 AM PDT By mapping the cell types and genes expressed in the human and mouse trigeminal ganglion, researchers have created an online resource for studying the molecular basis of headache and facial pain. |
| Researchers offer new treatment protocol for advanced head and neck cancer Posted: 28 Mar 2022 08:18 AM PDT The current treatment of patients diagnosed with advanced or metastatic head and neck cancer (HNC) is ineffective. Researchers have investigated and validated a potential treatment combination against the aggressive disease driven by hyper-activation of a specific signaling pathway, which is found in over 40 percent of HNC patients. |
| Deleting a protein might reduce cardiovascular disease Posted: 28 Mar 2022 08:17 AM PDT Macrophages travel through our arteries, gobbling fat. But fat-filled macrophages can narrow blood vessels and cause heart disease. Now, researchers describe how deleting a protein could prevent this and potentially prevent heart attacks and strokes in humans. |
| Relatedness and size interact in shaping cannibal aggression Posted: 28 Mar 2022 06:00 AM PDT New research finds that in addition to size difference, relatedness affects whether or not a poison frog tadpole is more likely to be eaten. |
