Drug company pipelines are developing new molecules to help people safely shed extra weight

Drugs that promise to help people lose weight have had a checkered past, such as the infamous fen-phen that was pulled from the market in 1997 after reports of heart valve damage.

Researchers reveal how bacteria make liquid protein droplets to survive harsh environments

Scientists have revealed how bacteria make tiny liquid droplets from proteins to help them survive harsh environments and thus reduce their chances of being killed by antibiotics.

Incorporating RNA-inspired breaking points to reduce plastic pollution

Once plastic products are used and discarded, they can linger in oceans, collecting in large "garbage patches" and harming sea life. One potential solution, a biodegradable polymer called polylactide (PLA), has so far not fully lived up to its promise, showing little sign of breakdown once in seawater.

Novel method enables quick identification of small active substance molecules

Secondary natural substances that occur in numerous plants, bacteria and fungi can be anti-inflammatory, can ward off pathogens or even prevent the growth of cancer cells. However, making use of the riches provided by nature's medicine cabinet and identifying new natural substances is time-consuming, costly and labour-intensive. A team of bioinformaticians at Friedrich Schiller University Jena has now developed a method that enables much faster and easier identification of small active substance molecules.

Brain immune cells take up large amounts of sugar at the beginning of neurodegenerative disease

At the beginning of neurodegenerative disease, the immune cells of the brain – the "microglia" – take up glucose, a sugar molecule, to a much greater extent than hitherto assumed.

Researchers improve understanding of molecular mechanisms underlying stomach’s acid pump

Nagoya University researchers and colleagues have improved understanding of the molecular mechanisms of a key protein that makes the stomach acidic. Their findings, published in the journal Nature Communications, could lead to better drugs for stomach ulcers and shed light on the functions of similar proteins across the human body.

Dimethyl sulfide emitted from the sea can never help in the formation of new clouds, study reveals

Stand on the ocean's shore and take a big whiff of the salt spray and you'll smell the unmistakably pungent scent of the sea. That ripe, almost rotting smell? That's sulfur.
