Researchers have captured the first atomic-level views of human SMUG1, a key enzyme involved in repairing damaged DNA. Every cell in your body is constantly battling damage to its DNA. Now, scientists have captured the first atomic level images of a key human repair enzyme in action, revealing how cells identify and remove some of [...]

A surprising backup pathway allows cells to make a crucial amino acid when their primary machinery fails. For decades, biologists believed cells had only one way to access a molecule they cannot live without. New research suggests they were wrong. Scientists at Montana State University have uncovered a previously unknown cellular survival pathway that allows [...]

A naturally occurring anti-inflammatory protein fragment is showing promise in early Parkinson’s disease research. Parkinson’s disease affects millions of people worldwide, yet current treatments mainly address symptoms rather than the underlying damage occurring in the brain. Now, researchers in Brazil have identified a promising new approach that targets a different aspect of the disease: inflammation. [...]

A copper-based drug helped the brain flush out Alzheimer’s toxins, cutting plaque buildup and improving memory in a promising new study. Scientists at Monash University have identified a promising new approach to tackling Alzheimer’s disease. In laboratory studies, a copper-delivering drug significantly lowered levels of toxic proteins linked to the disease while also improving long-term [...]

Semaglutide delivered dramatic weight loss and health benefits in adults over 65, offering new hope for healthier aging. A new analysis of data from the STEP clinical trial program suggests that semaglutide remains both effective and generally safe for older adults living with obesity. The research, conducted by Prof. Luca Busetto of the University of [...]

Researchers in Sweden have developed a machine-learning approach that embeds the laws of physics directly into neural networks. A new study from Chalmers University of Technology in Sweden shows that machine learning can become far more efficient when it starts with a built-in understanding of the laws of physics. Researchers found that giving an AI [...]

Bird flocks, bacterial swarms, and even crowds move according to interaction rules that appear to break one of physics’ most fundamental principles: Newton’s law of action and reaction. Birds can see much of what is happening around them, but when flying in a flock, they respond only to birds beside them or ahead of them. [...]

Scientists have found a way to make GPS remarkably accurate in city “urban canyons,” where navigation has long gone wrong. Most of us trust that the location shown by our GPS is accurate. But anyone who has tried navigating an unfamiliar city knows that is not always the case. You may be walking steadily down [...]

Oxford physicists have created an unconventional class of quantum superpositions from highly nonclassical states. Researchers at the University of Oxford have created a new class of quantum superpositions, including Schrödinger’s cat-like states, using building blocks that are themselves strongly nonclassical. The advance could support future quantum computing architectures based on more complex systems than conventional [...]

Researchers explored how different dietary changes could reduce the carbon footprint of food consumption. A single change at the dinner table could have a bigger climate impact than many people realize. Researchers in the UK found that replacing just one beef steak per week with salmon could significantly reduce food-related carbon emissions over time. In [...]

Researchers found that a magma’s thermal history may be a key factor in determining whether an eruption becomes more vigorous or remains relatively gentle. What happens deep beneath a volcano can determine whether an eruption unfolds as a slow-moving lava flow or explodes into towering fountains of molten rock. New research suggests that one overlooked [...]
