UNIGE scientists have identified a brain circuit that may be at the root of the social difficulties experienced by individuals with autism spectrum disorders. From birth, human survival relies on the ability to connect with others. This capacity, crucial for healthy development, appears to be dis
Researchers at the University of Oklahoma have made a discovery that could potentially revolutionize treatments for antibiotic-resistant infections, cancer and other challenging gram-negative pathogens without relying on precious metals.
Currently, precious metals like platinum and rhodium are used to create synthetic carbohydrates, which are vital components of many approved antibiotics used to combat gram-negative pathogens, including Pseudomonas aeruginosa, a notorious hospital-acquired infection responsible for the deaths of immunocompromised patients. However, these elements require harsh reaction conditions, are expensive to use and are harmful to the environment when mined.
In an innovative study published in the journal Nature Communications, an OU team led by Professor Indrajeet Sharma has replaced these precious metals with either blue light or iron, achieving similar results with significantly lower toxicity, reduced costs, and greater appeal for researchers and drug manufacturers.
A research group at the University of Stuttgart has manipulated light through its interaction with a metal surface so that it exhibits entirely new properties. The researchers have published their findings in Nature Physics.
“Our results add another chapter to the emerging field of skyrmion research,” proclaims Prof. Harald Giessen, head of the Fourth Physics Institute at the University of Stuttgart, whose group achieved this breakthrough. The team demonstrated the existence of “skyrmion bags” of light on the surface of a metal layer.

To address issues in stellarator reactors, Princeton Plasma Physics Laboratory has developed its QUADCOIL computer code for optimizing and accelerating the design process.
Vision is one of the most important human senses, yet more than 300 million people around the world are at risk of losing it due to various retinal diseases. Although recent treatments have helped slow the progression of these conditions, no effective therapy has been able to restore vision that has already been lost, until now. Researchers at KAIST have developed a new drug that successfully restores vision.
On March 30, KAIST announced that a research team headed by Professor Jin Woo Kim from the Department of Biological Sciences has created a treatment that regenerates retinal nerves to restore vision.
These electrical pulses are communicated with other neurons through connections between them called synapses. Individual neurons have branching extensions known as dendrites that can receive thousands of electrical inputs from other cells. Dendrites transmit these inputs to the main body of the neuron, where it then integrates all these signals to generate its own electrical pulses.
It is the collective activity of these electrical pulses across specific groups of neurons that form the representations of different information and experiences within the brain.
For decades, neuroscientists have thought that the brain learns by changing how neurons are connected to one another. As new information and experiences alter how neurons communicate with each other and change their collective activity patterns, some synaptic connections are made stronger while others are made weaker. This process of synaptic plasticity is what produces representations of new information and experiences within your brain.
For more than a century, electricity has flowed through wires, powering everything from the smallest gadgets to entire cities. However, what seemed like a distant dream—wireless energy transmission—may soon become a reality. This breakthrough technology, known as “power beaming”, promises to eliminate the need for physical infrastructure, delivering power directly from one point to another using electromagnetic waves.

Our brain’s ability to absorb fresh information — whether that means mastering a new task at work, memorizing the refrain of a song, or navigating unfamiliar streets — depends on a remarkable talent for neural self‑reinvention.
Every time we practice something novel, millions of tiny contacts between nerve cells subtly adjust their strength and neurons use multiple mechanisms to store knowledge.
Some connections, called synapses, amplify their signals to stamp in crucial details; others turn down the volume to clear away noise. Collectively these shifts are known as synaptic plasticity and for decades neuroscientists have cataloged dozens of molecular pathways that can nudge a synapse up or down.
