It's well known that consuming sugary drinks increases the risk of diabetes, but the mechanism behind this relationship is unclear. Now researchers show that metabolites produced by gut microbes might play a role. In a long-term cohort of US Hispanic/Latino adults, the researchers identified differences in the gut microbiota and blood metabolites of individuals with a high intake of sugar-sweetened beverages. The altered metabolite profile seen in sugary beverage drinkers... Read more ›

Researchers have developed a new microscopy technique to observe how ribosomes function in cells. With this method, they can monitor individual ribosomes as they convert mRNA into proteins. The researchers discovered that ribosomes help each other when encountering difficulties, a process they refer to as 'ribosome cooperativity'. This technique and the findings, published in Cell, provide insights into how proteins are made and offer other researchers a tool to better... Read more ›

It's been known for some time that radiation impacts the structural integrity of concrete. However, until now the details of this were unknown. Researchers can finally demonstrate what properties of concrete affect its structural characteristics under different neutron radiation loads. Their findings raise some concerns whilst reducing others; for example, quartz crystals in concrete can heal themselves, potentially allowing some reactors to run for longer than initially thought possible.

Researchers measured very precisely atomic masses of radioactive lanthanum isotopes and found an interesting feature in their nuclear binding energies. The discovery provides essential data for understanding how elements heavier than iron are produced in the Cosmos and triggers new research to elucidate the underlying nuclear structure causing this unexpected change in nuclear binding energies.

The rise of pastoralist peoples in the Eurasian steppes and their westward spread some 5,000 years ago may have been fueled by sheep herding and people exploiting their milk. As early as 8,000 years ago the team found evidence that farmers were deliberately selecting their flocks -- for example, for the genes coding for coat color. Sheep have been intertwined with human livelihoods for over 11,000 years. As well as... Read more ›

Researchers have discovered neurons in the fly larva mouth that allow the taste of food texture. The study found that the fly peripheral taste organ has neurons with texture-tasting mechanoreceptors that derive their ability from the painless gene. Read more ›

Key cells in the brain, neurons, form networks by exchanging signals, enabling the brain to learn and adapt at incredible speed. Researchers have now developed a 3D-printed 'brain-like environment' where neurons grow similarly to a real brain. Using tiny nanopillars, they mimic the soft neural tissue and the brain extracellular matrix fibers. This model provides new insights into how neurons form networks, as well as a novel tool to understand... Read more ›

Sharks and rays have populated the world's oceans for around 450 million years, but more than a third of the species living today are severely threatened by overfishing and the loss of their habitat. Palaeobiologists have now investigated whether and how global warming influences the diversity of sharks based on climate fluctuations between 200 and 66 million years ago. According to the study, higher temperatures and more shallow water areas... Read more ›
