Environmental scientists have published a series of significant recommendations to protect, conserve and study the world's coral reefs -- the 'canaries in the coal mine' of climate change.

Sodium is an essential micronutrient, but the amount we need is small. Three slices of bread or one teaspoon of table salt will do it, and chances are your daily sodium intake is far greater. More than 90% of Americans consume too much sodium, which can lead to hypertension, high blood pressure, and increased risk of heart disease and stroke. A new article provides a comprehensive review of scientific literature on sodium reduction strategies in food production.

A new study describes a breakthrough in the quest to improve photosynthesis in certain crops, a step toward adapting plants to rapid climate changes and increasing yields to feed a projected 9 billion people by 2050.

Genetic studies of children with hydrocephalus ('water on the brain') combined with mouse models indicate that in certain genetic subtypes, the condition arises due to abnormal neurodevelopment that disrupts mechanical stability of the brain. Treatment strategies need to optimize brain development beyond the current standard of simply draining brain fluid.

A new study pinpoints how an immune checkpoint protein called LAG3 modulates T cell activity, providing important insights for development of LAG3-blocking therapies for cancer and autoimmune disorders.

Scientists are exploring how human genetics impacts functions of the gut microbiome, and are expanding awareness of the role human genetics plays in shaping the microbiome.

Legalization of recreational marijuana reduces demand for costly prescription drugs through state Medicaid programs, according to a new analysis.

A new analysis conveys the moral distress that triage team members experienced while participating in a simulated crisis-care event in which they had to decide which patients would and would not be prioritized to receive life-sustaining resources.

Researchers have determined the atom-by-atom structure of the fermentation enzyme phosphoketolase by cryogenic electron microscopy. They identified details that were mistakenly characterized by X-ray crystallography yet are essential for correlating enzyme structure with enzyme function. These findings will help researchers produce chemical feedstocks in an environmentally sustainable manner, and thus lower the carbon footprint of the chemical industry.

Plastic rubbish is everywhere and now broken-down microplastics have been found in variable concentrations in blue mussels and water within the intertidal zone at some of southern Australia's most popular and more remote beaches. Researchers warn that this means microplastics are now finding their way into human food supplies -- including wild-caught and ocean-farmed fish and seafood sourced from the once pristine Southern Ocean and gulf waters of South Australia.

Noninvasive sound technology breaks down liver tumors in rats, kills cancer cells and spurs the immune system to prevent further spread -- an advance that could lead to improved cancer outcomes in humans.

Proteins are the molecular machinery that makes life possible, and researchers have long been interested in a key trait of protein function: their three-dimensional structure. A new study details a computational tool able to predict the structure protein complexes -- and lends new insights into the biomolecular mechanisms of their function.

A new study finds that some children with cerebral palsy and scoliosis do not require pelvic fixation when undergoing growth-friendly treatment. Researchers say those with a small enough pelvic and lower lumbar spine tilt may not need screws inserted into the pelvis, potentially avoiding several complications.
