Human DNA is built from long sequences of three-letter units made up of four nucleotides. These units, known as codons, tell cells which amino acids to use when building proteins. While several different codons can code for the same amino acid, this has often been viewed as simple redundancy in…

New research from Vanderbilt Health shows that both modern weight loss drugs and bariatric (weight loss) surgery can improve body composition in people with obesity. These treatments lead to a large drop in fat while also causing a smaller reduction in fat-free mass (including lean muscle). This balance matters because…

Chronic inflammation often develops quietly, without obvious pain or noticeable symptoms. Over time, however, it can contribute to serious health problems such as type 2 diabetes, heart disease, obesity, arthritis, and even cancer. Inside the body, this process is driven by immune cells that release chemical signals to respond to…

A large international collaboration between researchers at the University of Huddersfield and the University of Southampton has provided new insight into when and how modern humans, Homo sapiens, first settled New Guinea and Australia.

Researchers at Johns Hopkins Medicine report that a newly funded study by the National Institutes of Health is helping advance a potential new approach to Alzheimer’s disease treatment. The focus is a protein in the brain that produces a small but important gas. The protein, called Cystathionine γ-lyase, or CSE…

Autism BrainNet has released new survey results that reveal a major gap between public support for autism research and awareness of how that research is carried out. While most Americans recognize the importance of studying the autistic brain, far fewer understand the role that brain donation after death plays in…

New research suggests that wheat domestication was shaped by an intense evolutionary struggle for light and space. This competition pushed early crops to develop traits that helped them outgrow and outcompete neighboring plants, offering new insight into how crops evolve and how they might be improved in the future. The…

A new international study is calling into question long-standing assumptions about what makes elite sprinters so fast. The findings offer a fresh perspective that could reshape how Australia identifies and trains its next generation of speed athletes. Published in Sports Medicine, the research looks at sprinting through a dynamical systems…

I’ll admit something surprising. Even after years of stargazing, tracking planets, and scanning deep sky objects through a telescope, I only clearly noticed the Man in the Moon about five years ago. While studying the familiar dark plains and bright highlands, I somehow overlooked a pattern people have recognized for…

In 2023, scientists detected a subatomic particle called a neutrino hitting Earth with an energy level so extreme it seemed impossible. No known cosmic process can generate that much energy. The particle carried about 100,000 times more energy than anything ever produced by the Large Hadron Collider, the most powerful…

Planetary missions on the surface of Mars are carried out with extreme caution. Communication delays between Earth and robotic explorers can range from four to 22 minutes, and limited data transmission capacity adds another layer of constraint. Because of this, scientists must carefully plan each step in advance. Rovers are…

Quantum computers hold enormous promise, but they are still far from dependable. Their biggest weakness is instability, which causes the information they process to quickly break down. Researchers around the world are working to solve this problem, including a team in Norway. “In quantum computers, information is transmitted and stored…

Every second, countless electrical charges move through the human body. These microscopic signals are essential for life. They drive communication between cells, enable energy production, and support metabolism. None of this would work without the careful and controlled movement of charges across cell membranes and within cells. In many ways,…

A well-known 300-million-year-old fossil once believed to be the oldest octopus ever discovered has been reclassified after new analysis revealed it is something entirely different. The specimen had even earned a place in the Guinness Book of Records, but scientists now say that distinction was based on a misinterpretation. The…

Researchers have developed a powerful new way to map how brain cells connect by tagging neurons with molecular “barcodes.” Using this technique, they were able to chart thousands of neural connections in the mouse brain with remarkable speed and detail. This method could deepen understanding of how complex brain networks…
