As climate change drives more frequent and severe wildfires across boreal forests in Alaska and northwestern Canada, scientists are asking a critical question: Will these ecosystems continue to store carbon or become a growing ...

Deep beneath the surface of distant exoplanets known as super-Earths, oceans of molten rock may be doing something extraordinary: powering magnetic fields strong enough to shield entire planets from dangerous cosmic radiation ...

Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies. To observe distant black holes clearly, multiple radio telescopes must capture cosmic signals ...

By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San Andreas fault meets the Cascadia subduction zone, an area that could give rise to devastating major ...

Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among them, the atomic ion 173Yb+ has attracted growing interest because of its particularly rich energy ...

To stay healthy, our cells rely on a self-cleaning mechanism that removes defective or unnecessary components. This process, known as autophagy, has been linked not only to cellular maintenance but also to various diseases ...

Protein scientists could improve reproducibility and coordination across the field by rallying around a small, shared set of "model proteins," according to a new Perspective by Connecticut College chemist Marc Zimmer.

Maintaining cellular order is a major logistical challenge: Individual mammalian cells contain billions of protein molecules, which must be synthesized, deployed, and removed with precision. In the ubiquitin-proteasome system ...

Gold nanorods are promising photocatalysts that can use light energy to drive chemical reactions—such as converting CO₂ into usable fuels or producing hydrogen from water. In this process, the nanorods act like tiny antennas ...

Global change—a term that encompasses climate change and phenomena such as changes in land use or environmental pollution—is increasingly putting ecosystems around the world under pressure. Urban soils in particular are ...

LMU researcher Professor Alexander Urban and his team have developed a tool that could revolutionize the design of new materials. Synthesizer is a platform that combines automated chemical synthesis, high-throughput characterization, ...

A recent study shows that viruses in wild bees are closely linked to the flowers they visit and the availability of floral resources across the landscape. Researchers found that certain floral communities increase the likelihood ...
