Phys.org / Why some people are mosquito magnets while others get away unbitten
Some mosquitoes really are picky eaters. They will not just stick their proboscis into any old human. We know this anecdotally, with some people claiming they are always bitten while others are completely ignored, though ...
Phys.org / Venus's polygonal plains could point to a watery past
Venus may be overwhelmingly inhospitable today, but many planetary scientists believe that it wasn't always this way. Billions of years ago, some observational evidence suggested that our planetary neighbor may have looked ...
Medical Xpress / Discovery reveals aging human brains receive immune cell reinforcements from blood
The brain's immune system has long been thought to exist independently from the rest of the body, complete with its own specialized immune cells and a blood-brain barrier that limits what can travel into the brain.
Phys.org / Random physics helps model individual ant motion
Ants make up one of the most diverse groups of animals on the planet, with many species boasting remarkable physical abilities and social behaviors, and an overall species richness that far exceeds that of mammals. Various ...
Phys.org / First measurement of antineutrinos from spent nuclear fuel confirms emissions persist after reactor shutdown
Even when the lights go out and nuclear reactors are turned off, the story inside the reactor core still has a great deal to tell. Radioactive, long-lived fission products continue to decay for months or even years, producing ...
Phys.org / Scattered Roman bones point to potential fourth-century purge at Brading Villa
Disarticulated bones found scattered across a luxurious Roman villa on England's Isle of Wight may be evidence of a massacre carried out during a brutal political purge in the fourth century, a new study in Britannia suggests.
Phys.org / Fluorescent nanosensors help distinguish between healthy and diseased immune cells in blood samples
Researchers at Karolinska Institutet and SciLifeLab have developed a new method to analyze the condition of immune cells in the blood. The method has been tested on patients with atherosclerosis and can distinguish their ...
Phys.org / Atomic view of Alzheimer's disease peptide could inform new drugs
One of the hallmarks of Alzheimer's disease is the accumulation of a peptide in the brain known as amyloid beta. A new study published in Nature Communications on July 22 has uncovered the atomic structure of the peptide ...
Phys.org / Liquid nitrogen may have recently flowed across Pluto's heart-shaped glacier
A new study led by Southwest Research Institute (SwRI) provides evidence that liquid nitrogen is rising to Pluto's surface through cracks at the northern edge of Sputnik Planitia, part of the massive heart-shaped glacier ...
Phys.org / Bioengineers develop biochemical halo to cloak insulin-producing cells from body defenses
A protein known as interleukin 10 (IL-10) is the lynchpin of a new method to protect transplanted cells from host immune system attacks. Rice University researchers engineered a living factory to produce a localized biochemical ...
Tech Xplore / Optimizing software: Computing professor's 'egg' downsizes programs to make them more nimble
Many software tools, including compilers, optimizers and synthesizers, have a common task at their core. They must transform long, complicated programs into simplified equivalents. These scaled-down programs run faster and ...
Medical Xpress / ChatGPT can generate personality tests and predict people's responses before they take them
In iScience, scientists outline how they developed a method for generating personality assessment questionnaires with ChatGPT from any source text. To test the method, they applied it to both the DSM-5 and, as a deliberately ...
