Mathematical framework maps landscape of student knowledge via short quizzes

When we learn something new, that information does not exist in isolation. It integrates into the complex landscape of our knowledge, forging connections with existing ideas and opening up possibilities for new learning. ...

Stolen chloroplasts maintained by host-made proteins offer clues to plant cell origins

Every plant cell is the product of a biological merger billions of years ago. Chloroplasts are key structures in plants and algae that capture sunlight, but originally they were free-living bacteria that took up residence ...

Quantum computers could have a fundamental limit after all

The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, Tim Palmer at the University ...

How soil microbes may control the future of our planet

The soil beneath our feet is a huge carbon bank storing up to approximately three times more carbon than the entire atmosphere. That makes it a significant player in the future of our climate. If even a small fraction of ...

Why a canceled meeting feels so liberating

Unless your employer is Lumon Industries, where the "Severance" workday never ends, a canceled meeting can feel like a gift of limitless time. A Rutgers University study published in the Journal of the Association for Consumer ...

Drought spurs rise in antibiotic-resistant soil microbes

A new Caltech study indicates that drought increases the abundances of antibiotic-resistant microorganisms in soils, which directly correlates with an increase in antibiotic-resistant infections in hospitals. In other words, ...

New findings on the first steps in protein synthesis

In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first steps toward folding proteins into their correct three-dimensional structures. An international research ...

Hubble revisits Crab Nebula to track 25 years of expansion

Nearly a millennium ago, astronomers witnessed a brilliant new star blazing in the sky—a supernova so bright it was visible in daylight for weeks. Today, its expanding remnant, the Crab Nebula, continues to evolve 6,500 ...

Tracking Arctic freshwater flow from space

Arctic rivers wind through remote tundra and boreal forests, freezing solid in winter and surging each spring with snowmelt, eventually emptying into the ocean. Runoff—water that does not soak into the ground but instead ...

Online ad fraud is a feature, not a bug

Technological advancements and the dynamics of the platform economy make rooting out fraud more complicated than it may seem. With print media circulation and broadcast television viewership in free fall, a lot is riding ...

Saturn-mass world discovered orbiting two low-mass stars

Researchers report the discovery of a Saturn-sized exoplanet orbiting two M-dwarf stars, which are smaller and cooler than our sun. The findings from this discovery were published in the The Astronomical Journal and were ...

Planet trapped record heat in 2025: UN

The amount of heat trapped by Earth reached record levels in 2025, with the consequences of such warming feared to last for thousands of years, the UN warned Monday.

Measuring irreversibility in gene transcription

Living cells are fundamentally nonequilibrium systems, meaning they constantly spend energy through seemingly one-way, irreversible processes, such as transcribing DNA into RNA, to keep life going. But how that irreversibility ...
