Cells assembled into Anthrobots become biologically younger than the original cells they were made from

Modern humans have existed for more than 200,000 years, and each new generation has begun with a single cell—dividing, changing shape and function, organizing into tissues, organs, and limbs. With slight variations, the ...

A new method to control the rovibrational ground state of a single molecular hydrogen ion

The precise measurement of states in atomic and molecular systems can help to validate fundamental physics theories and their predictions. Among the various platforms that can help to validate theoretical predictions are ...

Penning-trap system enables loss-free transfer of protons between experimental sites

Protons are the basic building blocks of matter. Together with neutrons, they form atomic nuclei. These minute, positively charged particles have an antimatter counterpart, antiprotons. While the latter have a negative charge ...

Âé¶¹ÒùÔºicists uncover a metallic altermagnet with d-wave spin splitting at room temperature

For many years, physics studies focused on two main types of magnetism, namely ferromagnetism and antiferromagnetism. The first type entails the alignment of electron spins in the same direction, while the latter entails ...

Quantum genesis: The emergence of a flat universe and its mirror from nothing

I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the traditional singularity-based models of cosmology. Instead of a universe emerging from an infinitely ...
