Physical forces from gravity, muscle contraction, and more have strong impacts on how the cells in our bodies behave. For instance, weight-bearing exercise helps stave off osteoporosis because cells in our bones sense that force and build more bone to support it. Cells of our arteries sense the force from high blood pressure, which triggers biological responses to bring blood pressure down.

As artificial intelligence advances, computers demand faster and more efficient memory. The key to ultra-high-speed, low-power semiconductors lies in the "switching" principle—the mechanism by which memory materials turn electricity on and off. A South Korean research team has successfully captured the elusive moment of switching and its internal operational principles by momentarily melting and freezing materials within nano-devices—phenomena that were previously difficult to observe. The study provides a foundational blueprint for designing next-generation memory materials that are faster and consume less power based on fundamental principles.

The irregular, swirling motion of fluids we call turbulence can be found everywhere, from stirring in a teacup to currents in the planetary atmosphere. This phenomenon is governed by the Navier-Stokes equations—a set of mathematical equations that describe how fluids move.

From 1948 to 1953, a gold mine called Giant Mine released about 5 tons of arsenic trioxide per day into the environment around Yellowknife, Northwest Territories, Canada. Emissions declined from the 1950s until the mine closed in 2004, but the surrounding landscape remains highly contaminated with arsenic.

People are more likely to act helpfully in situations where there are poorer choices to give to others, according to a new study that tested willingness to help others in different contexts.

Quantum materials and superconductors are difficult enough to understand on their own. Unconventional superconductors, which cannot be explained within the framework of standard theory, take the enigma to an entirely new level. A typical example of unconventional superconductivity is strontium ruthenate, SRO214, the superconductive properties of which were discovered by a research team that included Yoshiteru Maeno, who is currently at the Toyota Riken—Kyoto University Research Center.

An international team of researchers has developed a breakthrough method for producing MXenes—an important family of two-dimensional materials—with unprecedented purity and control. The new "gas–liquid–solid" process enables the synthesis of pure MXenes with uniformly distributed halogen atoms on the surface and a precisely tunable surface composition. The method dramatically boosts their electrical conductivity and opens the door to high-performance electronics, sensors, and energy technologies.

In a new study published in Cell, scientists in the Bork Group at EMBL Heidelberg reveal that microbes living in similar habitats are more alike than those simply inhabiting the same geographical region. By analyzing tens of thousands of metagenomes, the team found that while most microbes adapt to a specific ecosystem, a rarer subset known as "generalists" can thrive across very different habitats.

For many years, the deep ocean has been seen as a nutrient-poor environment where microbes living in the water survive on very limited resources. But new research from the University of Southern Denmark (SDU) challenges that idea. A study led by SDU-biologists at the Department of Biology shows that nutrients might not be so sparse after all in the deep and that microbes have access to a hitherto unknown source of dissolved organic food.

Many ecologists hypothesize that, as global warming accelerates, change in nature must speed up. They assume that as temperatures rise and climatic zones shift, species will face local extinction and colonize new habitats at an ever-increasing rate, leading to a rapid reshuffling of ecological communities. A new study by researchers at Queen Mary University of London (QMUL) and published in Nature Communications shows this is emphatically not the case.
