LISA to the rescue: Using light to fix cell division

Cell division is a complex process. At the heart of this complexity is a membraneless organelle called the centrosome, which is made up of more than 200 components. It is responsible for clustering mitotic spindles, threadlike structures needed to separate genetic material. It has long remained unclear which parts of the centrosome are necessary and sufficient for spindle assembly.

Protein signaling cascade helps explain how plants respond to touch

Plants cannot run away when the wind picks up, rain lashes down or a hungry herbivore begins chewing on their leaves. Instead, they must sense their surroundings and adapt. Now, researchers have uncovered an important piece of the puzzle of what happens inside plants when they are exposed to touch, injury or other physical stimuli.

Canada's 2023 wildfires broke longstanding media caution around climate reporting

Fueled by record-breaking drought and unusually high temperatures, Canada's 2023 wildfire season was the worst in the country's history, with more than 15 million hectares (37 million acres) charred. Smoke blanketed the eastern seaboard, with health alerts keeping people indoors as skies turned an eerie orange.

AI structure prediction speeds discovery of 'molecular glues' to treat disease

A Baylor College of Medicine-led team has developed a strategy that combines the analysis of thousands of proteins with artificial intelligence to accelerate the discovery of small molecules called molecular glues to treat disease. Their approach, published in Nature Communications, has uncovered a new class of molecular glues that could neutralize harmful proteins linked to blood cancers and autoimmune diseases. The work also shows how AI-based structural modeling can help chemists optimize compounds well before experiments reveal how they work.

New feathered, winged dinosaur from China challenges our theories on bird and dinosaur evolution

A newly described feathered dinosaur found in northeastern China adds evidence supporting the theory that flight-related features evolved differently in various bird-like dinosaur groups. The findings, reported in Nature Communications, are based on an analysis of an exceptionally well-preserved fossil of a microraptorine (a small dinosaur with feathers and wings) found in a geological formation estimated to be between 145 and 100 million years old.

Under the Microscope: NASA-made material for moon manufacturing

Photos taken using a microscope reveal the colorful, kaleidoscope-like crystal structure of a new NASA-made material that could be used for manufacturing during future space missions. Developed at NASA's Glenn Research Center in Cleveland, the material could be created directly on the moon or Mars, allowing NASA to pack fewer supplies—saving weight and reducing launch costs.

Mobile crisis response programs get new measures of their impact on police calls

Communities across the country are debating the role mobile crisis response programs can play in emergency response. These programs typically take calls from 911 dispatchers involving mental health, substance use, welfare checks and other situations that do not require a law enforcement response.

Study finds trust is the missing ingredient for AI-driven food safety

Artificial intelligence promises to transform food safety by helping companies identify risks earlier, predict outbreaks and learn from patterns too rare for any one company to detect alone. But AI depends on one thing: large, diverse datasets.
