Virus-like particles enable gene activity tracking over time in the same cells

In recent years, scientists have developed methods to measure a cell's transcriptome, or all the RNA produced by a cell, to study the cell's identity and genetic activity. However, these methods rely on killing the cell to ...

How AI‑powered policing is endangering the public's trust in police

Since the release of ChatGPT in 2022, artificial intelligence (AI) has dominated the cultural landscape. Uptake across various sectors, including law enforcement, quickly followed, usually with minimal foresight and little ...

Pacific farmers are reviving traditional knowledge to tackle a changing climate

For thousands of years, farmers in the Pacific have lived in harmony with their environment. But rising temperatures, unpredictable rainfall and tired soils are testing even the most experienced hands.

Fungal age remains elusive as underground networks continually grow, split and recycle

Some of Earth's oldest living organisms may be right beneath our feet: not ancient trees or coral reefs but fungi. Yet despite their ubiquity and importance, scientists still don't know how long most fungi can live—or even ...

Hybrid bioprinter creates capillary networks narrower than 10 micrometers

More than 100,000 people are awaiting an organ transplant in the United States, with a new candidate added to the list every 10 minutes. Even if the transplant is carried out successfully, recipients must take immunosuppressive ...

Spontaneous magnons synchronize with external signals at room temperature

Signals ride on waves of one kind or another: light, sound, radio. But new carriers are needed to relay information in next-generation devices. Disturbances or waves in magnetic materials called magnons could be an efficient ...

First electrically pumped perovskite polariton laser diode solves a decades-long challenge

Resolving a long-standing problem in semiconductor physics and optoelectronics, a team of researchers from Skoltech—a VEB.RF group institution—and their colleagues from ITMO University and HSE University have for the first ...

The surprising physics hiding in a single handful of beach sand

Sand has a way of getting everywhere on a beach day—and for some, it can make or break the whole trip. There's the way it whips through the air just as sandwiches are being unwrapped, the way it turns blisteringly hot underfoot ...

Pump that recreates human heartbeat blood flow on lab chips inspired by an accordionist

For more than 25 years, lab-on-a-chip technology has allowed researchers to model human organs and blood vessels using real human cells in artificial microscopic environments. These microphysiological systems (MPS) may replicate ...

Quantum currents turn a nano 'soccer ball' into a powerful molecular electromagnet

Driving an electric current through a molecule can create a magnetic field. Yet in practice, such fields are often too weak to be detected experimentally. Through theoretical modeling, researchers at the Institute of Science ...
