Meat and fish fraud are global problems, costing consumers billions of dollars and potential problems for people with allergies, religious or cultural restrictions. Current methods to detect this fraud, while accurate, are slower than inspectors would like. Now, researchers have optimized their handheld MasSpec Pen to identify common types of meat and fish within 15 seconds.

Researchers have developed a lifetime microplastic exposure model that accounts for variable levels from different sources and in different populations. The new model indicates a lower average mass of microplastic accumulation than previous estimates.

Drinking beetroot juice promotes a mix of mouth bacteria associated with healthier blood vessels and brain function, according to a new study of people aged 70-80.

Researchers have succeeded in using a cochlear implant to directly measure brain waves. These brainwaves indicate in an objective way how good or bad a person's hearing is. The research results are important for the further development of smart hearing aids.

A genetic variant linked to male infertility has been discovered, and this knowledge could help improve the diagnosis and management of men who carry it.

Scientists have detailed how they developed and used a computational model to simulate cell division, cell migration and apoptosis in the hope of understanding how these processes affect the development of the brain.

Scientists report the latest prime editing technology, prime editing, expands the “genetic toolbox” for more precisely creating disease models and correcting genetic problems.

New technology suggests that using electronic deterrents could be a valid approach to reducing the incidence of shark bites.

New research published in Science, looked at a newly discovered, endangered songbird located only in South America—the Iberá Seedeater—and found that this bird followed a very rare evolutionary path to come into existence at a much faster pace than the grand majority of species.

Researchers have uncovered a protein that could be key to blocking the most common bacterial cause of food poisoning in the United States. According to the study, the protein known as CiaD facilitates cell entry by Campylobacter and takes control of important cell processes by changing the composition of a protein complex inside the cell.
