An early-career physicist mathematically connects timelike and spacelike form factors, opening the door to further insights into the inner workings of the strong force. A new lattice QCD calculation connects two seemingly disparate reactions involving the pion, the lightest particle governed by the strong interaction. One reaction is known as the spacelike process, where an electron is bounced off a pion. The second reaction, known as the timelike process, is when an electron and antielectron collide, annihilate each other, and produce two pions. The lattice QCD numerical calculation is simultaneously able to describe the spacelike and timelike processes, demonstrating the interconnectedness of different reactions described by QCD. While this connection had been observed experimentally, now physicists have the math to corroborate it.

Brine pools are one of the most extreme environments on Earth, yet despite their high salinity, exotic chemistry, and complete lack of oxygen, these pools are teeming with life and offer a unique record of Earth's rainfall patterns.

Like the teeth of a comb, a microcomb consists of a spectrum of evenly distributed light frequencies. Optical atomic clocks can be built by locking a microcomb tooth to a ultranarrow-linewidth laser, which in turn locks to an atomic transition with extremely high frequency stability. That way, frequency combs act like a bridge between the atomic transition at an optical frequency and the clock signal at a radio frequency that is electronically detectable for counting the oscillations – enabling extraordinary precision. The researchers’ photonic chip, on the righthand side of the image, contains 40 microcombs generators and is only five millimeters wide.

(A) Embryonic tissues elongate via convergent extension, where cell polarization directs active stresses, driving rearrangements (T1 transitions). (B) Fluctuating stresses fluidize tissues, enabling morphogenesis. (C) Key cell processes—force production, polarization, and adhesion—are modeled in robotic units: actomyosin as motorized gears, chemoreceptors as photodiodes, and cadherins as rolling magnets. Polarity conventions differ from biology. (D) Photos of two robotic units (top and isometric views), showing gear rotation and applied forces. Scale bar: 5 cm.
