For the first time, NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a ...

Forgetting the name of a loved one may be one of the first signs people notice of dementia, but it’s rarely the first warning sign your brain gives. Changes in the brain that lead to neurodegenerative diseases like Alzheimer’s and dementia start showing up decades before symptoms arrive, and the chemicals at work inside the body can often tip us off to these changes well ahead of time.

A recent study found that a blood protein called GDF15, which is released when cells are under stress, could serve as one of the earliest warning signs of dementia. After tracking more than half a million people for 15–25 years, researchers discovered that those with higher GDF15 levels before age 55 were significantly more likely to develop dementia later in life...

Researchers at The University of Texas at El Paso have developed a way to 3D-print an essential battery component in nearly any shape. Their innovation could free engineers from the constraints of standard rechargeable battery sizes and allow energy storage to be built directly into the devices the batteries power.

The work, detailed in a study published in Communications Engineering, centers on gel polymer electrolytes, the material inside a battery that carries the ions (the particles that carry the electrical charge) between the electrodes—the two terminals where chemical reactions occur and electric...

Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits a small, cool star called a red dwarf...
