The honeycomb patterns which are often found in salt deserts in Death Valley, US, and Bolivia, among other places, look like something from another world. Researchers can now explain the origin of the mysterious patterns.

The demand for vanillin vastly outstrips the natural resources of this flavoring agent. A chemical process is thus used to produce the required large quantities of vanillin from petroleum, which is far less expensive than obtaining the substance from fermented genuine vanilla pods. Another alternative is to make vanillin from lignin, a waste product of the wood pulping industry. A team has now managed to further enhance their method of electrochemical production of vanillin from lignin in that they employ a 'green' oxidation method for this purpose.

Geoscientists have developed a cheap and environmentally friendly method for the synthesis of cerianite, a rare earth mineral which holds promise for the treatment of diseases associated with inflammation, including cancer.

Certain diseases, including Alzheimer's, are currently considered 'undruggable' because traditional small molecule drugs can't interfere with the proteins responsible for the illnesses. But a new technique that specifically targets and breaks apart certain proteins -- rather than just interfering with them -- may offer a pathway toward treatment. Researchers have now designed a compound that targets and breaks down a post-translationally modified protein closely associated with Alzheimer's disease.

Glacier National Park is home to around 50 Canada lynx, more than expected, surprising scientists who recently conducted the first parkwide occupancy survey for the North American cat. The survey reveals the iconic predator resides across most of Glacier's 1,600 square-mile landscape, although at lower densities than in the core of its range further north.

Wastewater can provide clues about a community's infectious disease status, and even its prescription and illicit drug use. But looking at sewage also provides information on persistent and potentially harmful compounds, such as per- and polyfluoroalkyl substances (PFAS), that get released into the environment. Now, researchers report an unexpected source of these substances in wastewater systems -- toilet paper.

Scientists thought a gold-throated hummingbird was a new species. DNA revealed that it's a hybrid of two different species, each with pink throats. The discovery sheds light on how birds produce feather colors and how hummingbirds evolved their dazzling hues.

Researchers have identified gut bacteria that are associated with dementia with Lewy bodies. Changing the levels of three bacteria, Collinsella, Ruminococcus, and Bifidobacterium, may delay the onset and progression of this neurodegenerative disease.

New research has estimated the carbon footprints and diet quality of six popular diets. The vegan and vegetarian diets were found to be produce the least amount of carbon dioxide while keto and paleo diets ranked lowest in sustainability and diet quality.

Engineers devised a way to purify protein drugs during manufacturing. Their approach, which uses nanoparticles to rapidly crystallize proteins, could help make protein drugs more affordable and accessible, especially in developing countries.

A new study of New Zealand blue whales' vocalizations indicates the whales are present year-round in the South Taranaki Bight and their behavior is influenced by environmental conditions in the region.

Researchers have discovered what they believe is the earliest use of steel in Europe -- on Iberian stone pillars from the Final Bronze Age.

Researchers have published an updated metric for prioritizing species' conservation that incorporates scientific uncertainty and complementarity between species, in addition to extinction risk and evolutionary distinctiveness.

A review of evidence from prior research provides new support for the possibility that the evolution of larger brains in some species was enabled through increased energy investment by parents in their offspring.

In 2011, scientists recorded a previously unknown feeding strategy in whales around the world. Now, researchers in Australia think they may have found evidence of this behaviour being described in ancient accounts of sea creatures, recorded more than 2,000 years ago. They believe that misunderstandings of these descriptions contributed to myths about medieval sea monsters. Whales are known lunge at their prey when feeding, but recently whales have been spotted at the surface of the water with their jaws open at right angles, waiting for shoals of fish to swim into their mouths. A clip of this strategy was captured in 2021 and went viral on Instagram. This strategy seems to work for the whales because the fish think they have found a place to shelter from predators, not realising they are swimming into danger. It's not known why this strategy has only recently been identified, but scientists speculate that it's a result of changing environmental conditions -- or that whales are being more closely monitored than ever before by drones and other modern technologies.

Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were already highly evolved in the Late Jurassic.
