NewsScientists solve 66 million-year-old mystery of how Earth’s greenhouse age ended
Experts studying foraminifera fossils have discovered that concentrations of calcium in the sea dropped by more than half across the last 66 million years, which likely caused Earth’s massive drop in temperature.

NewsScientists discover novel immune ‘traffic controller’ hijacked by virus
Researchers have discovered a tissue protein that acts as a central ‘traffic controller’ for immune cells and can be hijacked by a virus to weaken immune responses. Cytomegalovirus (CMV) can hijack this system by producing a protein that blocks CD44 function on stromal cells.

NewsExperts propose fibre as first new essential nutrient in 50 years - as gut microbiome research gathers pace
Nutrition experts are calling for dietary fibre to be officially recognised internationally as an essential nutrient - the first ‘new’ essential nutrient in more than 50 years. They point out that the gut microbiome exists almost exclusively on the dietary fibre we eat.

NewsScientists explore how gut bacteria alter the flavor of Black Ivory coffee beans
Coffee beans that pass through the digestive tracts of animals get their unique flavors from the activity of gut microbes, report researchers. Bacterial activity that reduces the pectin content of Black Ivory coffee could be the source of its smoother, chocolaty, and less bitter flavor.
