Natural clay reveals a new way to control ion transport at the angstrom scale

Researchers at the National Graphene Institute have shown that naturally occurring channels within a common clay mineral can respond to pressure, voltage and pH, offering possibilities for controlling the movement of ions through extremely small, confined spaces. The study, published in Advanced Materials, focuses on vermiculite, a naturally abundant layered clay whose structure contains channels only a few angstroms high, providing naturally confined pathways through which ions can move.

Molecular surface design achieves over 100 million-fold tuning of porous liquid viscosity

Porous liquids combine permanent nanoscale cavities with fluidity, making them promising for applications like carbon dioxide capture, gas separation and other chemical processes. Their viscosity must be tailored to the intended application: Lower-viscosity liquids are easier to pump and circulate while facilitating faster heat and mass transfer, whereas higher-viscosity liquids provide greater structural stability in membrane formation.

Africa's rocks hold ancient stories. We need better ways to document and protect them

From the Vredefort Dome in South Africa (the world's oldest and largest known meteorite impact structure) to the volcanic lakes of the Great Rift Valley in Kenya, Africa's landscapes hold some of Earth's oldest stories. Morocco's M'Goun UNESCO Global Geopark records more than 200 million years of geological history, while Tanzania's Ngorongoro-Lengai landscape brings together a vast caldera, an active volcano and the fossil record of Olduvai Gorge.

'America's Nobel' prizes go to sleep and hemophilia researchers, and to Michael J. Fox for Parkinson's advocacy

This year's Lasker Awards — coveted prizes for biomedical research that are sometimes called "America's Nobel Prizes" — have gone to scientists behind fundamental discoveries in sleep science and to researchers who developed a groundbreaking treatment for hemophilia.Additionally, a Lasker Award for public service went to actor Michael J. Fox for his advocacy for patients with Parkinson's disease that has helped advance research into the neurodegenerative condition. The prizes, each of which comes with an honorarium of $250,000, will be presented in person Sept. 17 in New York City. The awardees were announced Wednesday (Sept. 9) by the Lasker Foundation, which was established in 1942 by the ...

Molecular antennae make light-activated molecular switches more sensitive

From targeted cancer treatments to self-healing materials and microscopic robots, many emerging technologies depend on molecules that can be controlled with light. Researchers at Tohoku University have now developed a way to make these light-responsive molecules much more sensitive to visible light by using a molecular antenna. The breakthrough gives scientists better control over molecular photoswitches remotely and potentially expands their use in medicine and advanced materials. The findings are published in the Journal of the American Chemical Society.

Beryllium signal identifies stars that have swallowed rocky planets

An international team led by researchers from the University of São Paulo (USP) in Brazil has developed an innovative method to identify stars that have consumed the planets around them. The technique detects variations in the abundance of beryllium, a relatively rare chemical element, and could open a new window into studying the evolution of planetary systems.

If alien civilizations use hyper-efficient computers, they will have a distinct energy signal we can detect

Love it or hate it, artificial intelligence is likely here to stay. Its ravenous need for computational power has overwhelmed chip manufacturers and power companies alike. While our current AI obsession is likely a bubble ready to burst, we won't simply stop using computers. Since their first invention, computers have continued to grow more powerful, and our civilization has grown ever more dependent on them. Computation defines our civilization. Perhaps computational power is what defines any advanced civilization. If that's the case, then the most advanced civilizations in the universe would push computing to its most powerful and efficient state.

Terbium's elusive plus-4 form emerges under ordinary lab conditions, opening possibilities for rare-earth metals

Chemists in a new study led by the University of Iowa report they have isolated and described in detail an atypical state of the rare-earth metal terbium, an advance that could expand its use in quantum technologies, including computing and advanced sensors. The study, "Structural and spectroscopic characterization of a Tb(IV) polyoxometalate," is published in the journal Nature Communications.

Cacao genetics could help breeders reduce heavy metal levels in cocoa beans

Cadmium is a naturally occurring, toxic heavy metal found in many soils across Latin America and the Caribbean, where cacao trees are widely cultivated. It makes its way into cocoa seeds, called beans, that are roasted and made into chocolate, according to the Food and Agriculture Organization of the United Nations (FAO)—but some cacao varieties take up less of the toxic element than others. An international team of researchers, including Penn State scientists, found genetic differences in how two varieties managed cadmium uptake and facilitated the metal's movement throughout the plant.

How seeds decide whether to wake up in salty soil

Researchers have discovered a system that helps seeds survive when there is too much salt in the soil. The system helps young germinating embryos keep the right balance of sodium and potassium as they begin to grow. Understanding how it works could eventually help scientists develop crops that grow better in salty soils.

These bacteria can change their diet to survive inside the body

The human body fights staph infections by starving it of essential nutrients. Staph, it turns out, is remarkably good at changing what's on the menu. Staphylococcus aureus—the infamous agent behind MRSA and most staph infections—needs sulfur to build proteins and other materials essential for survival. In a new Michigan State University study, published in the Journal of Bacteriology, researchers found the bacterium can adjust its diet depending on what sources remain available.

Electrochemical system extracts pure hydrogen from ammonia at substantially lower temperatures

As a liquid that is easily stored and transported, ammonia (NH3) is an attractive carrier for hydrogen, which is used in fuel cells, semiconductor manufacturing, chemical processing and other applications. However, breaking ammonia into hydrogen and nitrogen typically requires high temperatures, and the resulting gas mixture must undergo additional purification before the hydrogen can be used in many applications.

Watch the first-ever footage of a rare deep-sea squid in the northeastern Pacific

A bizarre squid has been filmed haunting the northeastern Pacific Ocean for the first time. Researchers spotted the bigfin squid (Magnapinna) via remote video while using an uncrewed submersible to explore underwater mountains, known as seamounts, at a depth of more than 10,000 feet (3,000 meters) off the coast of California. The footage, captured Aug. 7, represents the first confirmed live observation of a bigfin squid in the northeastern Pacific, according to the Monterey Bay Aquarium Research Institute (MBARI), whose scientists made the discovery with collaborators from the National Oceanic and Atmospheric Administration (NOAA).Olívia Soares Pereira, a deep-sea ecologist and postdoctoral ...
