Scientists used a 200-ton “neutrino scale” to measure the elusive particles.

Time crystals that persist indefinitely at room temperature could have applications in precision timekeeping.

We have all seen crystals, whether a simple grain of salt or sugar, or an elaborate and beautiful amethyst. These crystals are made of atoms or molecules repeating in a symmetrical three-dimensional pattern called a lattice, in which atoms occupy specific points in space. By forming a periodic lattice, carbon atoms in a diamond, for example, break the symmetry of the space they sit in. Physicists call this “breaking symmetry.”

Scientists have recently discovered that a similar effect can be witnessed in time. Symmetry breaking, as the name suggests, can arise only where some sort of symmetry exists. In the time domain, a cyclically changing force or energy source naturally produces a temporal pattern.

A five-year experiment to genetically modify deer ticks, or black-legged ticks, using CRISPR/Cas9 ends in success, marking a first in biology.

I’m doing an abbreviated newsletter this week as I want to spend most of my energy amplifying the brave journalists on the ground reporting about this scary time. As so many have said — far more eloquently than me — the invasion of Ukraine is a story that impacts all of us, whether we’re on the ground there or not. And it’s hard to celebrate a funding round when scary times are the moment.

My brilliant colleagues put together a story on how the tech industry is responding to Russia’s invasion of Ukraine; I urge you to read it. While the situation is still ongoing, it’s clear that it’s already a tech story. And startups such as Grammarly, Ajax, People AI and Preply, backed by some of the world’s biggest VCs, are scrambling to support employees and operations amid the invasion.
