Rare image of Tatooine-like planet is closest to its twin stars yet
2025-12-11
In a discovery that’s fit for a movie, Northwestern University astronomers have directly imaged a Tatooine-like exoplanet, orbiting two suns.
While obtaining an image of a planet beyond our solar system is already rare, finding one that circles two suns is even rarer. But this new world is extra exceptional. It hugs its twin stars more tightly than any other directly imaged planet in a binary system. In fact, it is six times closer to its suns than other previously discovered exoplanets.
The discovery provides an unprecedented look at how planets move and form around ...

Missing piece of myelin disturbs the brain’s rhythm
2025-12-11
Our nerve cells are surrounded by a protective layer (myelin). This protective layer allows signals to pass between cells incredibly quickly. But what happens when this layer goes missing from cells that transfer signals over longer distances? Maarten Kole’s research group studied this question in mice, looking specifically at nerve fibres travelling from the brain’s outer layer to the thalamus, a crucial switching station deep in the middle of the brain.
Processing sensory information involves continuous communication between the brain’s outer layer (cerebral cortex) and the thalamus. Such an exchange, for example, ...

New FAU research strengthens evidence linking alcohol use to cancer
2025-12-11
As Americans gear up for the holiday season, new research offers a timely reminder to reflect on the long-term health effects of raising a celebratory glass – or two. Alcohol is known to increase the risk of several cancers even at moderate levels. Yet drinking remains widespread, and important questions persist about how both the frequency and amount of alcohol people consume shape their cancer risk.
Moreover, risks differ across groups, and existing alcohol policies rarely emphasize their link to cancer.
To help close these critical gaps, researchers from Florida Atlantic University’s Charles E. Schmidt College of Medicine, conducted a comprehensive systematic ...
Gut health à la CAR T
2025-12-11
Ever notice that as you get older, some foods no longer sit with you the same? This could be due to a breakdown of the intestinal epithelium, a single layer of cells that forms the organ’s lining. The intestine plays a crucial role in many health functions, including digestion. Under normal conditions, the entire intestinal epithelium typically regenerates every three to five days. However, with damage from old age or cancer radiation, regeneration can stop or slow. That can lead to inflammation and diseases like leaky gut syndrome.
Now, Cold Spring ...
