Redesigned carbon molecules boost battery safety, durability and power

Research published in the Journal of the American Chemical Society demonstrates a new way to make carbon-based battery materials much safer, longer lasting, and more powerful by fundamentally redesigning how fullerene molecules are connected.

Today’s lithium-ion batteries rely mainly on graphite, which limits fast-charging speed and poses safety risks due to lithium plating. These research findings mean progress toward safer electric vehicles, longer-lasting consumer electronics, and more reliable renewable-energy storage.

For computational devices, talk isn’t cheap: Research reveals unavoidable energy costs across all communication channels

Every task we perform on a computer—whether number crunching, watching a video, or typing out an article—requires different components of the machine to interact with one another. “Communication is massively crucial for any computation,” says former SFI Graduate Fellow Abhishek Yadav, a Ph.D. scholar at the University of New Mexico. But scientists don’t fully grasp how much energy computational devices spend on communication.

Alzheimer’s disease can be reversed in animal models to achieve full neurological recovery

For over a century, Alzheimer’s disease (AD) has been considered irreversible. Consequently, research has focused on disease prevention or slowing, rather than recovery. Despite billions of dollars spent on decades of research, there has never been a clinical trial of a drug for AD with an outcome goal of reversing disease and recovering function.

Now, a research team from University Hospitals, Case Western Reserve University, and the Louis Stokes Cleveland VA Medical Center has challenged this long-held dogma in the field. They tested whether brains already badly afflicted with advanced AD could recover.

The study, led by Kalyani Chaubey, Ph.D., from the Pieper Laboratory, is published in Cell Reports Medicine.

Scientists boost mitochondria to burn more calories

Researchers have developed experimental drugs that encourage the mitochondria in our cells to work a little harder and burn more calories. The findings could open the door to new treatments for obesity and improve metabolic health.

Obesity is a global epidemic and a risk factor for many diseases, including diabetes and cancer. Current obesity drugs require injections and can cause side effects, so a safe way to boost weight loss could deliver significant public health benefits.

The study, led by Associate Professor Tristan Rawling from the University of Technology Sydney (UTS), has just been published in Chemical Science, where it was highlighted as “pick of the week.”

An AI-based blueprint for designing catalysts across materials

Hydrogen peroxide is widely used in everyday life, from disinfectants and medical sterilization to environmental cleanup and manufacturing. Despite its importance, most hydrogen peroxide is still produced using large-scale industrial processes that require significant energy. Researchers are thus seeking cleaner alternatives.

A team of researchers has made a breakthrough in this regard, developing a new computational framework that helps identify effective catalysts for producing hydrogen peroxide directly from water and electricity.

The work focuses on the two-electron water oxidation reaction, an electrochemical process that can generate hydrogen peroxide in a more localized and potentially sustainable way.

Research uncovers the telltale tail of black hole collisions

When black holes collide, the impact radiates into space like the sound of a bell in the form of gravitational waves. But after the waves, there comes a second reverberation—a murmur that physicists have theorized but never observed.

An international collaboration has for the first time simulated in detail what these whispers—called late-time gravitational wave tails —might “sound” like.

“So far, we’ve only seen tails in simplified models, not in full simulations of numerical relativity,” said Leo Stein, University of Mississippi associate professor of physics and astronomy and co-author of the study. “These are the first fully numerical simulations where we saw tails clearly.”

This Crystal Doesn’t Melt Like Ice: Physicists Capture a Strange New Phase

New research offers clearer insight into how phase transitions unfold at the atomic scale in real materials. When ice turns into water, the change happens almost instantly. Once the melting temperature is reached, the rigid structure of the solid collapses and becomes a flowing liquid. This abrup

Dark Matter Breakthrough: Physicists Crack “Big Bang Theory” Puzzle

A new theoretical study suggests fusion reactors could do more than generate energy, they might also produce particles linked to dark matter. Researchers at the University of Cincinnati say they have worked out, at least on paper, how fusion reactors could produce subatomic particles known as axi

Astronomers Finally See What Really Happens During Stellar Nova Explosions

Using Georgia State’s CHARA Array, an international team of scientists has uncovered unexpected complexity in how stars explode. Astronomers have obtained images of two stellar explosions, called novae, just days after they erupted, capturing them in detail never achieved before. These observatio
