Astronomers find Earth-like exoplanets common across the cosmos

25 April 2025 at 15:34
Astronomers have discovered that super-Earth exoplanets are more common across the universe than previously thought. While it can be relatively easy to locate worlds that orbit close to their star, planets with wider paths can be difficult to detect. Still, researchers estimated that for every three stars, there should be at least one super-Earth present with a Jupiter-like orbital period, suggesting these massive worlds are extremely prevalent across the universe.

Why our waistlines expand in middle age: Stem cells

25 April 2025 at 15:33
It's no secret that our waistlines often expand in middle-age, but the problem isn't strictly cosmetic. Belly fat accelerates aging and slows down metabolism, increasing our risk for developing diabetes, heart problems and other chronic diseases. Exactly how age transforms a six pack into a softer stomach, however, is murky. New research shows how aging shifts stem cells into overdrive to create more belly fat.

Breakthrough approach for diagnosing TB could significantly improve detection

24 April 2025 at 01:43
A new strategy for tuberculosis (TB) screening provides a solution to problems with current TB screening, which does not always accurately detect disease. Simultaneously screening for both active and dormant TB infection could save lives, curtail infection rates, and rewrite the story of the continued spread of this disease. Researchers hope that this new approach will inform guidance from global health organizations and key decision-makers on the most effective way to screen for TB.

Nanophotonic platform boosts efficiency of nonlinear-optical quantum teleportation

24 April 2025 at 21:29
Researchers have long recognized that quantum communication systems would transmit quantum information more faithfully and be impervious to certain forms of error if nonlinear optical processes were used. However, past efforts at incorporating such processes could not operate with the extremely low light levels required for quantum communication.
