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.
Phys.org / Bird-derived gene tool inserts plant DNA 30 times more efficiently than CRISPR
In a rapidly changing climate landscape, the plants we rely on for food, textiles and more face a multitude of challenges, including rising temperatures, drought and disease. Caltech's Gözde Demirer, the Clare Boothe Luce ...
Phys.org / Experiment upends beliefs on how electrons actually behave in warm dense matter
Researchers at European XFEL, Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Rostock University and other collaborating institutions have used high-precision experiments to demonstrate that the most widely used models for the ...
Phys.org / Scientists design a clay that can prevent fruits and vegetables from rotting too quickly
Avocados from Chile, bananas from Costa Rica, tomatoes from southern Spain, mangoes from Brazil. A large share of the fruit and vegetables we eat have traveled across the globe before they reach store shelves here at home. ...
