Injectable nanoparticles make blind retinas respond to light in preclinical study‎

An international research team has developed microscopic particles that can make blind retinas respond to light. The particles act as tiny light receptors. Researchers inject them into the eye, where they settle close to nerve cells in the retina. When light hits the particles, it triggers electrical and chemical processes that can activate the nerve cells and prompt them to send signals toward the brain.

Corals show 'vaccine-like' responses after pathogen exposure‎

To boost corals' resilience amid rising sea temperatures and the spread of disease, KAUST researchers have found that controlled, low-level exposure to dead pathogenic cells can help corals resist future infection.

Tech solution that makes drone operations much more wildlife friendly‎

This summer, Norwegian news has reported (in Norwegian) multiple stories about Lofoten residents who shot at drones out of sheer frustration. But not everyone exposed to approaching drones has a gun with which to defend themselves.

Physicists crack the math connecting ultraslow quantum magnetism to ultrafast black-hole physics‎

A team led by University at Buffalo physicists has found a mathematical solution that shows how a frustrated quantum magnet can transition from ultraslow behavior to ultrafast, highly entangled behavior resembling that of a black hole.

From swarming bacteria to tissue cells, living matter defies classic physical models of motion‎

A new study led by researchers from Ben-Gurion University of the Negev (BGU) reveals that living matter violates previously known physical principles of symmetry when cellular flows form and break down collective patterns. The research, published in Nature Physics, challenges conventional liquid-crystal physics by showing that moving single-celled bacteria and human respiratory cells spontaneously break mirror symmetry, moving in curved, irreversible spiral paths.

Psychologists provide tips on how to talk about identity‎

Imagine your child asks you out of the blue, "If we speak Spanish, will they take you away?" Or imagine them suddenly asking what an offensive slur means. When a child asks these types of questions, it can be difficult to trace them back to a specific news story or event. But you may not need to. The question itself tells you that your child is trying to make sense of something they heard.

AI companions may erode social skills among isolated users, framework suggests‎

As AI companions become more commonplace, new research from Singapore Management University (SMU) and Duke-NUS Medical School argues that the real question is no longer whether these technologies are beneficial or harmful, but who benefits, who is most at risk and how society can ensure AI serves everyone equitably.

What is your dog really saying? AI is helping researchers decode animal communication‎

Is a dog's bark simply an expression of emotion, or does it contain specific information that humans cannot understand? Artificial intelligence (AI) can already analyze thousands of animal sounds and identify patterns that would go unnoticed by the human ear. But researchers are asking a far more ambitious question: Could technology one day help us understand what animals are actually saying?

Short 'logic check' warnings may improve how people assess climate arguments‎

In the climate debate, people are exposed to a lot of different information and opinions. A short warning that an argument may contain a logical fallacy helps people evaluate information more critically.

RHIC data reveal intriguing dip in momentum fluctuations in high-density nuclear matter‎

Scientists using the STAR detector to study particle collisions at the Relativistic Heavy Ion Collider (RHIC) have found an intriguing dip in their data in a relatively unexplored region of the nuclear phase diagram—a map of how nuclear matter behaves under various conditions of temperature and density. The dip appears in data tracking collision-by-collision variations in the momenta of particles emerging from collisions between gold nuclei at RHIC, near RHIC's lowest collision energies. These collisions create the highest-density nuclear matter and may indicate that something interesting is happening in that dense region of the phase diagram. The findings are described in a paper just published in Physical Review Letters.
