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, should be unitary. But gr…

To find sterile neutrinos, think small

Experiments have spotted anomalies hinting at a new type of neutrino, one that would go beyond the standard model of particle physics and perhaps open a portal to the dark sector. But no one has ever directly observed this hypothetical particle.

Some of the biggest asteroids in our Solar System

Astronomers have imaged 42 of the largest objects in the asteroid belt, located between Mars and Jupiter. The observations reveal a wide range of peculiar shapes, from spherical to dog-bone, and are helping astronomers trace the origins of the asteroid…

Toward more energy efficient power converters

Researchers extend the mathematical approach called automatic differentiation from machine learning to the fitting of model parameters that describe the behavior of field-effect transistors. This allowed the parameters to be extracted up to 3.5 times f…

Optimal blood pressure helps our brains age slower

People with elevated blood pressure that falls within the normal recommended range are at risk of accelerated brain aging, according to new research. The research also found optimal blood pressure helps our brains stay at least six months younger than …

How to better identify dangerous volcanoes

The more water is dissolved in the magma, the greater the risk that a volcano will explode. A new study now shows that this simple rule is only partially true. Paradoxically, high water content significantly reduces the risk of explosion.
