UK scientists find link between proteins related to blood clots and long Covid
Biomarker discovery indicates that sufferers from brain fog and fatigue post-virus could be treated with anticoagulantsScientists have identified molecular signatures in the blood that are linked to brain fog, other cognitive problems and fatigue in patients who are diagnosed with long Covid after catching the virus.Raised levels of two different proteins were more common in people who developed...
Colleagues laud slain University of North Carolina materials scientist
Five thousand mourners attended a vigil yesterday at the University of North Carolina (UNC) at Chapel Hill to grieve the shooting death Monday of faculty member and materials scientist Zijie Yan. Police have charged one of his Ph.D. students with the killing in a campus research building. Shocked colleagues described Yan as a gifted scholar and mentor who helped pioneer the use of light...
Mapping the SARS-CoV-2 spike protein could provide insight into vaccine development
Although the COVID-19 pandemic was the first time most of humanity learned of the now infamous disease, the family of coronaviruses was first identified in the mid-1960s. In a new study, molecular biologist Steven Van Doren, a scientist in the University of Missouri College of Agriculture, Food and Natural Resources, has uncovered unexpected actions of a key player in how the coronavirus infects...
Southern California's 'water doctor' pushes for transformation to adapt to climate change
When Adel Hagekhalil speaks about the future of water in Southern California, he often starts by mentioning the three conduits the region depends on to bring water from hundreds of miles away: the Los Angeles Aqueduct, the Colorado River Aqueduct and the California Aqueduct.
Rising temperatures linked to increased child neglect
As temperatures rise, so does the maltreatment of children, according to a new study from a researcher in the LBJ School of Public Affairs at The University of Texas at Austin. The study, released as a National Bureau of Economic Research working paper, offers new insights into how climate change will affect child welfare.
Digging deeper into how vaccines work against parasitic disease

Scientists unpick how lung cells induce immune response to influenza
- ScienceDaily
- 23/8/31 22:42
Researchers have discovered some new and surprising ways that viral RNA and influenza virus are detected by human lung cells, which has potential implications for treating people affected by such viruses.
Do artificial roosts help bats? Experts say more research needed
Artificial roosts for bats come in many forms—bat boxes, condos, bark mimics, clay roosts, and cinder block structures, to name a few—but a new conservation practice and policy article from researchers at the University of Illinois Urbana-Champaign suggests the structures haven't been studied rigorously enough and may harm bats in some scenarios. The article, published in Conservation Biology,...
Could insights from ants help people build better transportation networks?
Could ants' nests hold the secret to reducing traffic congestion on the 405 Freeway?
Nearly half of dog owners are hesitant to vaccinate their pets, finds study
A new study has found that US dog owners who harbor mistrust in the safety and efficacy of childhood and adult vaccines are also more likely to hold negative views about vaccinating their four-legged friends.
NASA's LRO observes crater likely from Luna 25 impact
NASA's LRO—the Lunar Reconnaissance Orbiter—spacecraft has imaged a new crater on the moon's surface that is likely the impact site of Russia's Luna 25 mission.
Illuminating new horizons: Navigating nonlinear scattering with precision
In the intricate world of light, a journey through inhomogeneous media often leads to distortions in space, time, spectrum, and polarization. These distortions, detrimental to applications like optical manipulation, imaging, and communication, have long posed a challenge. Enter the art of wavefront shaping (WS)—a potent tool for correcting these wave maladies in linear optics. But that's not...
Galaxies in JWST’s Mirror are Closer than They Appear
- Astronomy.com
- 23/8/31 22:25
Recent announcements from the James Webb Space Telescope (JWST) team have shown galaxies in the very early universe are far more advanced, mature, and evolved than they ought to be. But that might be because we’ve been systematically overestimating the distances of those galaxies, as new research demonstrates. Measuring distances in space is a trickyContinue reading "Galaxies in JWST’s...
Biochemists focus on degrading key cancer-driving protein as a potential approach to stop cancer growth
Case Western Reserve University biochemical researchers have identified a new function of a key protein that leads to cancer—a finding they believe could lead to more effective treatments for a range of cancers and other diseases.
Drenched but alive, Floridians survey hurricane damage
Residents in the US state of Florida on Thursday cleaned up after rain and flooding caused by Hurricane Idalia wreaked havoc before the storm weakened and headed out to sea.
The 'Puss in Boots' effect: How a dog's eye size changes a woman's voice pitch
New scientific research that explores inter-species communication has discovered that women's vocal pitch increases when addressing dogs who have larger eyes.
Technology using all-optical mechanisms has potential to record actions that last a femtosecond
Imagine an action that occurs within a femtosecond, or one-quadrillionth of a second: atomic transitions, charge transfers and dynamics, biochemical processes. Now imagine being able to record that action so it can be studied in further detail.
Webb reveals new structures within iconic supernova
NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared...
'Suicidal' mechanism discovered in ion channel receptors enables the sensing of heat and pain
The ability to accurately detect heat and pain is critical to human survival, but scientists have struggled to understand on a molecular level exactly how our bodies sense these potential risks.
New research on fruit flies provides key insights into the nutrients essential for embryo development
It is well known in development biology that a mother's egg provides abundant nutrients that are essential for an embryo to develop. But does it matter where in the developing embryo the nutrients are stored?
