Phys.org / Real-time imaging reveals 'RNA hub' driving adaptive immune response
A lot of things need to go right on a molecular level for immune cells to launch an adaptive response to an infection. B cells can produce different classes of antibodies tailored for specific infections through controlled ...
Phys.org / Local species trends may flag global extinction risk, global study finds
New research from the University of St. Andrews has shown that higher extinction risk is associated with a higher frequency of decreasing local prevalence of species, in an analysis of one of the most comprehensive long-term ...
Phys.org / Branched silver sensor offers more sensitive light-based drug measurements in blood plasma
Medications can save lives, yet for some drugs, the concentration in a patient's bloodstream determines whether a treatment is effective or whether harmful side effects may occur. Researchers at the Leibniz Institute of Photonic ...
Phys.org / Corrected Pantheon+ analysis of supernovae challenges accelerating universe claim
Research led by the Tata Institute of Fundamental Research, Mumbai, along with Professor Subir Sarkar from the University of Oxford, questions the widely accepted argument that the expansion rate of the universe is accelerating ...
Phys.org / Newly described Australian ballista spider builds a spring-loaded snare to catch a single ant species
An international team of researchers has discovered a remarkable new spider species in the rainforest of North Queensland that spins an ingenious and powerful spring-actuated snare to catch a single species of ant—one ant ...
Phys.org / How languages recycle parts of words to avoid confusion
Many languages recycle words, giving them different meanings. For example, in English, "run" can mean to move quickly but also to manage something, like "run a company." In Spanish, "lengua" is both the word for tongue and ...
Phys.org / Broken time-reversal symmetry phase in kagome metals may establish conditions for superconductivity
Physicists have long suspected that a peculiar quantum state lurks inside a class of materials known as kagome metals, but proving its existence has been elusive. Now, a team led by Yeongkwan Kim at the Korea Advanced Institute ...
Phys.org / Marmoset monkeys adapt their voices to sound more like their social partners, study finds
Many animal species that live in groups are known to adjust their behavior to strengthen their social bonds or increase their coordination with others around them. For instance, humans and some other animals exhibit vocal ...
Phys.org / How oxygen sneaks into a corked wine bottle long before the first pour
The main reason for sealing wine bottles with a cork is to protect the liquid from oxygen. However, it is not an impermeable barrier, and a small amount of air leaks in, which is not always entirely bad news. The gas helps ...
Phys.org / Poo emoji, earthworm castings and pasta all obey the same coiling theory, physicists find
Ask a child to draw some poo, and the shape will invariably be the same: a coil, broad at the base and pointy at the top, similar to a spiral swirl of soft-serve ice cream. In fact, the often-used poo emoji has this exact ...
Phys.org / Long-dismissed gas emerges as a hidden driver of urban air pollution
Researchers from Tampere University and the University of Helsinki have identified an unexpected chemical process that may influence the formation of air pollution particles in urban environments. The study shows that nitric ...
Phys.org / New findings challenge idea that human bodies simply got bigger and bigger over time in a steady line
The biggest jump in body size among our ancestors happened around 2–2.5 million years ago, with the appearance of Homo rudolfensis or Homo erectus/ergaster, rather than gradually across the whole human family tree.
