Scientists have developed an automated workflow that could accelerate the discovery of new pharmaceutical drugs and other useful products. The new automated approach could analyze chemical reactions in real time and identify new chemical-reaction products much faster than current laboratory methods.

The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon -- a carbon atom bonded to four other carbon atoms. But now, scientists have uncovered a potential cost-effective way to produce these tricky motifs.

A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions.

The rusty-patched bumblebee, once common in the United States, has declined from about 90% of its former range. Researchers conducted the first range-wide genetic study of the endangered species to inform recovery efforts.

An international research team is attracting the attention of experts in the field with computational results on the behavior of ring polymers under shear forces: They showed that for the simplest case of connected ring pairs, the type of linkage -- chemically bonded vs. mechanically linked -- has profound effects on the dynamic properties under continuous shear. In these cases novel rheological patterns emerge.

Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.

One of the most fundamental interactions in physics is that of electrons and light. In an experiment, scientists have now managed to observe what is known as the Kapitza-Dirac effect for the first time in full temporal resolution. This effect was first postulated over 90 years ago, but only now are its finest details coming to light.

Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as 'greener' and less smelly than solvent-based options. And they are often advertised as containing little-to-no volatile organic compounds (VOCs). But, according to new research, some of these paints do contain compounds that are considered VOCs, along with other chemicals of emerging concern.

Scrub mints are among the most endangered plants you've probably never heard of. More than half of the 24 species currently known to exist are considered threatened or endangered at the state or federal level. In a new study, researchers show there are likely more scrub mint species waiting to be scientifically described. And at least one species has been left without federal protection because of a technicality.

The oldest trees in the forest help to prevent the disappearance of endangered species in the natural environment, according to a new study. This is the case of the wolf lichen -- threatened throughout Europe --, which now finds refuge in the oldest trees in the high mountains of the Pyrenees. This study reveals for the first time the decisive role of the oldest trees in the conservation of other living beings thanks to their characteristic and unique physiology.

Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the high temperatures and energy needed to manufacture it. But by improving on a well-known electrochemical reaction and orchestrating a 'symphony' of lithium, nitrogen and hydrogen atoms, engineers have developed a new ammonia production process that meets several green targets.

In 2022 and 2023, biologists from research institutes in the UK and the Falkland Islands led two expeditions to South Georgia to study the impacts of invasive species on this cold and rugged sub-Antarctic island. They report that several invasive plants and invertebrates rapidly colonized the new ground exposed by melting glaciers, leaving few pristine areas for native species. With ongoing climate change, more research is needed across the world to understand how invasive species impact the fragile ecosystems that develop after glacier melting.

A broader past could mean a brighter future for Canada lynx in the U.S., according to recent research. The study indicates that lynx might do well in the future in parts of Utah, central Idaho and the Yellowstone National Park region, even considering climate change and the lack of lynx in those areas now. Using a model validated by historic records, researchers first found that in 1900, Canada lynx had more suitable habitat in the U.S. than the few northern corners of the country where they are found currently. The study showed the elusive big cat likely roamed over a larger area in the Pacific Northwest, Rocky Mountains, Great Lakes region and parts of New England.

While Wyoming is home to some of North America's most abundant populations of pronghorn that have largely been stable in recent years, a new analysis shows that many herds are experiencing long-term declines in fawn production.
