3D structure of key membrane repair proteins revealed by cryo-electron microscopy

3D structure of key membrane repair proteins revealed by cryo-electron microscopy

Researchers from the Göttingen Cluster of Excellence Multiscale Bioimaging (MBExC) have uncovered the 3D structure of the membrane proteins myoferlin and dysferlin using high-resolution cryo-electron microscopy.

El Niño and La Niña transitions affect tropical cyclone development half a world away

El Niño and La Niña transitions affect tropical cyclone development half a world away

The butterfly effect suggests that small changes in a system can have a large impact on eventual outcomes. One metaphor used to illustrate this concept is a butterfly flapping its wings only to cause a hurricane across the ocean. While meteorologists' current cause-and-effect understanding of weather isn't this granular, researchers are actively investigating how changes in temperature, rainfall, wind patterns, etc. can impact weather phenomena halfway across the world.

Myosin makes the moves to keep cell processes humming along

Myosin makes the moves to keep cell processes humming along

Biomolecular condensates are distinct molecular communities made of DNA, RNA and proteins that "condense" molecules to key locations inside cells. Intense efforts have focused on uncovering the numerous ways in which condensation is controlled, modulated and regulated inside cells.

Twisting light for memory: New chiral photonic device enables real-time control of light polarization and data storage

Twisting light for memory: New chiral photonic device enables real-time control of light polarization and data storage

As fast as modern electronics have become, they could be much faster if their operations were based on light, rather than electricity. Fiber optic cables already transport information at the speed of light; to do computations on that information without translating it back to electric signals will require a host of new optical components.

Glaphene: 2D hybrid material integrates graphene and silica glass for next-generation electronics

Glaphene: 2D hybrid material integrates graphene and silica glass for next-generation electronics

Some of the most promising materials for future technologies come in layers just one atom thick, such as graphene, a sheet of carbon atoms arranged in a hexagonal lattice, prized for its exceptional strength and conductivity. While hundreds of such materials exist, truly merging them into something new has remained a challenge. Most efforts simply stack these atom-thin sheets like a deck of cards, but the layers typically lack significant interaction between them.

A new pathogenic fungus is threatening bats

A new pathogenic fungus is threatening bats

One fungus, two species, millions of dead bats: A study published in the journal Nature has analyzed 5,000 samples of a fungus that is responsible for the largest recorded pathogen-caused mortality in mammals. An international team of researchers, led by a doctoral candidate at the University of Greifswald, produced the study in collaboration with partners from France, Bulgaria, Finland and Ukraine and several hundred volunteers.

Filtered car emissions still turn toxic after sunlight exposure, study reveals

Filtered car emissions still turn toxic after sunlight exposure, study reveals

A new international study led by Helmholtz Munich and the University of Rostock reveals that emissions from modern gasoline cars—despite meeting the currently strictest European emission standards EURO 6d—can become significantly more harmful after being released into the atmosphere. The findings, published in Science Advances, challenge the assumption that filtered exhaust from EURO 6d-compliant vehicles is inherently safe.

The other great wall? Exploring Asia's Medieval Wall System

The other great wall? Exploring Asia's Medieval Wall System

Archaeologists have excavated a medieval frontier garrison in Mongolia, suggesting some monumental walls on the Eurasian steppe were not built to defend against enemy attack, but rather to control the movement of people and display dynastic power.
