Ten new gravitational waves found in LIGO-Virgo's O3a data

In the last seven years, scientists at the LIGO-Virgo Collaboration (LVC) have detected 90 gravitational waves signals. Gravitational waves are perturbations in the fabric of spacetime that race outwards from cataclysmic ...

New antenna spreads good vibrations in fusion plasma

If you want to catch a firefly, any old glass jar will do. But when you're trying to bottle a star—the goal of fusion energy research—the bottle needs to be very special. A tokamak is one type of fusion bottle, capable ...

Penguin-inspired propulsion system (w/ Video)

Back in 1991, Nature published a picture from the IMAX movie Antarctica, along with the caption: "Emperor penguins may be waddling jokes on land, but underwater they can turn into regular rockets…accelerating from 0 to ...

How to defend the Earth from asteroids

Researchers propose solutions for urine sample splash dilemma

Urinating into a cup may be a medical necessity for monitoring the health of the kidney and other issues, but it's often uncomfortable, embarrassing and messy—especially for women. But what if there were a way to comfortably ...

A 5-sigma standard model anomaly is possible

One of the best chances for proving beyond-the-standard-model physics relies on something called the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The standard model insists that the CKM matrix, which describes the mixing of quarks, ...
