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...

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.

A new approach to stop cancer growth?

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.

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,...

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

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...

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...
