World's biggest terrestrial carbon sinks are found in young forests - More than half of the carbon sink in the world's forests is in areas where the trees are relatively young—under 140 years old—rather than in tropical rainforests, research at the University of Birmingham shows.

Suicide system in tuberculosis bacteria might hold key to treatment - Tuberculosis (TB) is one of the top ten causes of death worldwide. In 2017, 10 million people around the world fell ill with TB and 1.3 million died. The genome of the bacterium that causes TB holds a special toxin-antitoxin system with spectacular action: once the toxin is activated, all bacterial cells die, stopping the disease. An international research team co-led by the Wilmanns group at EMBL in Hamburg investigated ...

Light-based production of drug-discovery molecules - Photoelectrochemical (PEC) cells are widely studied for the conversion of solar energy into chemical fuels. They use photocathodes and photoanodes to "split" water into hydrogen and oxygen respectively. PEC cells can work under mild conditions with light, which makes them also suitable for other catalyzing reactions that turn organic molecules into high added-value chemicals, like those used to develop drugs.

Solid-state catalysis: Fluctuations clear the way - The use of efficient catalytic agents is what makes many technical procedures feasible in the first place. Indeed, synthesis of more than 80 percent of the products generated in the chemical industry requires the input of specific catalysts. Most of these are solid-state catalysts, and the reactions they make possible take place between molecules that adsorb to their surfaces.

Sound waves let quantum systems 'talk' to one another - Researchers at the University of Chicago and Argonne National Laboratory have invented an innovative way for different types of quantum technology to "talk" to each other using sound. The study, published Feb. 11 in Nature Physics, is an important step in bringing quantum technology closer to reality.

Linking sensing to signaling during plant immunity - Plant defense against invading pathogens relies upon effective recognition of non-self organisms and a subsequent signaling response characterized by reprogramming of host gene expression and localized cell death to combat infection and provide resistance. At a molecular level, plant responses are initiated by the recognition of so-called effectors by intracellular receptors in a process known as effector-triggered immunity (ETI). While t...

Predicting sequence from structure - One way to probe intricate biological systems is to block their components from interacting and see what happens. This method allows researchers to better understand cellular processes and functions, augmenting everyday laboratory experiments, diagnostic assays, and therapeutic interventions. As a result, reagents that impede interactions between proteins are in high demand. But before scientists can rapidly generate their own custom molecules capable of...

Indigenous hunters have positive impacts on food webs in desert Australia - Australia has the highest rate of mammal extinction in the world. Resettlement of indigenous communities resulted in the spread of invasive species, the absence of human-set fires, and a general cascade in the interconnected food web that led to the largest mammalian extinction event ever recorded. In this case, the absence of direct human activity on the landscape may be the cause of the extinctions, according to a...

Meteorite source in asteroid belt not a single debris field - A new study published online in Meteoritics and Planetary Science finds that our most common meteorites, those known as L chondrites, come from at least two different debris fields in the asteroid belt. The belt contains many debris fields created from former dwarf planets, or dwarf planets in the making, that collided long ago. These fragments, called asteroids, continue to collide, producing the meteorites that fall to Earth to...

Diagnosing 'art acne' in Georgia O'Keeffe's paintings - Even Georgia O'Keeffe noticed the pin-sized blisters bubbling on the surface of her paintings. For decades, conservationists and scholars assumed these tiny protrusions were grains of sand, kicked up from the New Mexico desert where O'Keeffe lived and worked. But as the protrusions began to grow, spread and eventually flake off, people shifted from curious to concerned.
