Phys.org / No brain required: This is how the single-celled Stentor learns
Scientists have known for more than a century that a single-celled organism with no nerve cells—much less a brain—can behave in ways that resemble learning. But those observations only went so far. How the organism did that ...
Phys.org / Thinner than hair and stretchable like rubber, this new shield tackles a space-age problem in one layer
Shielding materials are essential in key modern industrial settings—such as spacecraft, nuclear power plants, semiconductor equipment, and advanced medical devices—to protect both equipment and personnel from electromagnetic ...
Medical Xpress / The Bondi Beach terror attack mobilized a team of volunteer medics. Here's what we learned
Warning: this article contains details of injuries sustained during a terrorist attack.
Tech Xplore / Human-guided AI system could strengthen advanced reactor monitoring and control
Nuclear reactors generate reliable, low-carbon electricity by using heat from nuclear fission to turn turbines. These steady energy producers are a crucial component of clean power generation. Nuclear engineers are responsible ...
Phys.org / At just four nanometers thick, this metal starts behaving in a way physicists did not expect
Researchers in the University of Minnesota Twin Cities have discovered a powerful new way to control the electronic behavior of a metal—by manipulating the atomic properties of materials where they meet. The study, published ...
Phys.org / How giants that vanished 10,000 years ago triggered ripple effects that are still felt today
Between 50,000 and 10,000 years ago, many of the world's largest mammals disappeared. Picture creatures like saber-toothed cats with 7-inch fangs and elephant-sized sloths. Woolly mammoths whose curved tusks grew longer than ...
Phys.org / Observing exotic quasiparticle states in kagome superconductor CsV₃Sb₅
A research team led by Prof. Hao Ning of the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Anhui University and the University of Science and Technology of China, has identified ...
Medical Xpress / Rethinking mRNA vaccines: Liver targeting can suppress immunity, while muscle boosts it
A new study by researchers at the Icahn School of Medicine at Mount Sinai overturns a longstanding assumption about how mRNA vaccines generate immunity, revealing that certain non-immune cells help determine vaccine effectiveness.
Tech Xplore / Solving the 'Whac-a-mole dilemma': A smarter way to debias AI vision models
In today's hospitals and clinics, a dermatologist may use an artificial intelligence model for classifying skin lesions to assess if the lesion is at risk of developing into a cancer or if it is benign. But if the model is ...
Phys.org / Hidden stripe pattern lets microscopes auto-focus across 400 times deeper range
Anyone who has ever used a microscope knows that it takes time to bring a sample into sharp focus. Each time you move the slide, the image blurs, and you have to stop and carefully turn a knob to bring everything back into ...
Science X / Dreaming while awake: Dream-like states are not confined to sleep
We tend to take for granted that the thoughts associated with sleep have a particular quality: We often describe them as elusive, abstract, or marked by a certain strangeness. Yet a study conducted by researchers from the ...
Science X / Wild parrots quickly learn to eat new foods by copying their friends
Wild parrots learn whether new types of food are safe to eat by observing other members of their social group, allowing dietary knowledge to spread rapidly through the community, according to a study by Julia Penndorf at ...
