Hidden role of garnet reveals how Earth's 660-km seismic boundary forms

Nearly 660 kilometers (410 miles) beneath Earth's surface lies one of the planet's most important internal boundaries. Known as the 660-km seismic discontinuity, it separates the mantle transition zone from the lower mantle and plays a central role in controlling how heat and mat

Light flips bacterial signaling enzyme between two shapes, unlocking how signals travel

Researchers at the University of Bayreuth and Forschungszentrum Jülich have demonstrated that specific light-sensitive enzymes—so-called sensor histidine kinases (SHKs)—transmit their signal through a light-controlled change in asymmetry. With their new study, the researchers con

Synchronized infrared lasers control molecular shape changes and expose hidden fingerprint

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two highly synchronized infrared (IR) laser beams can control molecules as they switch between different structural conformations. Their study provides a new wind

Purine-heavy DNA sequences protect Bacillus subtilis genes from Rho termination

In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating RNA into proteins—worked so closely in tandem that they were effectively attach

If we force online platforms to control harmful content, where does that leave sex ed?

Most of us have attended sex ed classes in school. If we're lucky, we'll learn about consent and how to roll a condom onto a banana. But the classroom rarely goes into the specifics of sexual health and well-being—including what to do when a condom breaks.

Small-molecule switches put therapeutic CRISPR editing under on-demand control in living t

In a study published in Science Translational Medicine, a team of researchers led by Dr. Wang Yu from the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences developed PRINCE and Little Prince, dual small-molecule-controlled genome editing systems that a

Bacterial protein reveals a hidden rule for controlling calcium

A small change in acidity can transform the world around us. A squeeze of lemon changes the taste of food. Vinegar preserves vegetables. Stomach acid helps break down a meal. These familiar effects come from protons—tiny charged particles that can reshape chemical interactions.

Controlling magnetic chirality could help memory pack in more data

Magnetic storage devices, like a computer's hard disk drive, utilize magnets to represent binary data. However, as these devices are downsized, stray magnetic fields generated by individual magnetic components can interact with neighboring elements to cause operational malfunctio

Atomic 'domino effect' found to drive phase changes in a two-dimensional crystal

Phase transformations—in which a material changes from one crystal structure to another, thereby acquiring dramatically different properties—are ubiquitous in nature. Understanding the microscopic mechanisms of these transformations is essential for controlling material propertie
