| New economic model finds wetlands provide billions in filtration value Posted: 25 Jan 2022 02:32 PM PST Southern Ontario wetlands provide $4.2 billion worth of sediment filtration and phosphorus removal services each year, keeping our drinking water sources clean and helping to mitigate harmful and nuisance algal blooms in our lakes and rivers. |
| Scientists discover new avian immunological pathway Posted: 25 Jan 2022 01:48 PM PST Biomedical scientists have discovered a new immune pathway in chickens that viruses may be targeting. The discovery, which has implications also for diseases affecting other birds, sheds greater light on birds' immune responses to zoonotic viruses -- specifically, how those may differ from responses seen in humans. |
| Stem cell discoveries hold potential to improve cancer treatment Posted: 25 Jan 2022 01:24 PM PST Recent discoveries by stem cell scientists may help make cancer treatment more efficient and shorten the time it takes for people to recover from radiation and chemotherapy. |
| Faulty BRCA genes linked to prostate and pancreatic cancers Posted: 25 Jan 2022 01:24 PM PST Faulty versions of the BRCA1 and BRCA2 genes are well known to increase the risk of breast cancer in men and women, and in ovarian cancer. Now BRCA1 and BRCA2 have been linked to several other cancers, including those that affect men. |
| How a smart electric grid will power our future Posted: 25 Jan 2022 12:10 PM PST A novel plan that offers partnership in keeping the United States electric grid stable and reliable could be a win-win for consumers and utility operators. |
| Silicon fluorescence shines through microcracks in cement, revealing early signs of damage Posted: 25 Jan 2022 12:10 PM PST Scientists and engineers discover fluorescence from silicon nanoparticles in cement and show how it can be used to reveal early signs of damage in concrete structures. |
| Hospitalization for COVID-19 linked to greater risk of later readmission or death Posted: 25 Jan 2022 12:10 PM PST A large study conducted in England found that, compared to the general population, people who had been hospitalized for COVID-19 -- and survived for at least one week after discharge -- were more than twice as likely to die or be readmitted to the hospital in the next several months. |
| Hungry yeast are tiny, living thermometers Posted: 25 Jan 2022 12:10 PM PST Researchers report that a yeast cells can actively regulate a process called phase separation in one of their membranes. During phase separation, the membrane remains intact but partitions into multiple, distinct zones or domains that segregate lipids and proteins. The new findings show for the first time that, in response to environmental conditions, yeast cells precisely regulate the temperature at which their membrane undergoes phase separation. |
| Atomic Armor for accelerators enables discoveries Posted: 25 Jan 2022 12:10 PM PST Protective coatings are common for many things in daily life that see a lot of use: we coat wood floors with finish; apply Teflon to the paint on cars; even use diamond coatings on medical devices. Protective coatings are also essential in many demanding research and industrial applications. |
| Fat injections could treat common cause of foot pain, plantar fasciitis Posted: 25 Jan 2022 10:37 AM PST A novel technique that transplants a patient's own fat into the sole of their foot could offer relief to those suffering from a common and painful condition called plantar fasciitis. |
| How the timing of dinner and genetics affect individuals’ blood sugar control Posted: 25 Jan 2022 09:40 AM PST Eating dinner close to bedtime, when melatonin levels are high, disturbs blood sugar control, especially in individuals with a genetic variant in the melatonin receptor MTNR1B, which has been linked to an elevated risk of type 2 diabetes. The high melatonin levels and food intake associated with late eating impairs blood sugar control in carriers of the MTNR1B genetic risk variant through a defect in insulin secretion. |
| Vision loss and retinal changes in Stargardt disease Posted: 25 Jan 2022 09:40 AM PST Researchers developed and validated an artificial-intelligence-based method to evaluate patients with Stargardt, an eye disease that can lead to childhood vision loss. The method quantifies disease-related loss of light-sensing retina cells, yielding information for monitoring patients, understanding genetic causes of the disease, and developing therapies to treat it. |
| Asymmetry is key to creating more stable blue perovskite LEDs Posted: 25 Jan 2022 09:40 AM PST For the first time, researchers have created blue LEDs using layers of metal halide perovskite linked with asymmetrical bridges, solving a critical instability problem. |
| Lead lurking in your soil? New Chicago project maps distribution Posted: 25 Jan 2022 08:26 AM PST Lead haunts old homes in chipping paint and pipes, but it also lurks outside, in soil. It's the stuff of mud pies and garden plots, crumbling from boot treads to join household dust in forgotten corners. It's easily overlooked, but soil can be an important source of lead where children live and play. |
| 'Lefty' tightens control of embryonic development Posted: 25 Jan 2022 08:26 AM PST A protein known as Lefty pumps the brakes as human embryos begin to differentiate into the bones, soft tissues and organs that make us. |
| Posted: 25 Jan 2022 08:26 AM PST Modelling the heart in 3D using combined imaging techniques can help predict heart rhythm abnormalities, or arrhythmias, in patients with the genetic heart disease hypertrophic cardiomyopathy. |
| Southern Ocean storms cause outgassing of carbon dioxide Posted: 25 Jan 2022 08:25 AM PST Storms over the waters around Antarctica drive an outgassing of carbon dioxide into the atmosphere, according to a new international study. The research group used advanced ocean robots for the study, which provides a better understanding of climate change and can lead to better global climate models. |
| An unexpected attraction of nucleic acids and fat Posted: 25 Jan 2022 06:30 AM PST All cells on Earth are enveloped in a fatty layer of lipids. Lipid membranes protect the content of the cells, including genetic information such as RNA and DNA. A new study reveals how lipids and RNA can directly interact and how this regulates RNA activity in unexpected ways. The study could help explain how RNA could be regulated in primordial or synthetic biological systems and lead to improvements in the design of RNA vaccines. |
| Novel research identifies fresh 'mixers' in river pollution 'cocktail' Posted: 25 Jan 2022 06:29 AM PST Water quality in rivers is affected by underpinning 'natural' hydrogeological and biogeochemical processes, as well as interactions between people and their environment that are accelerating stress on water resources at unprecedented rates. Pollutants can move at different speeds and accumulate in varying quantities along rivers where the mix of the complex 'cocktail' of chemicals that is making its way towards the ocean is constantly changing, a new study reveals. |
