Northwestern University researchers studying the gut bacteria of Scott and Mark Kelly, NASA astronauts and identical twin brothers, as part of a unique human study have found that changes to certain gut “bugs” occur in space.The Northwestern team is one of 10 NASA-funded research groups studying the Kelly twins to learn how living in space…

Liquorice and its natural sweetener, glycyrrhizin, can have long-term harmful effects on the development of the fetus. 

Traffic modeling has been of interest to mathematicians since the 1950s. Research in the area has only grown as road traffic control presents an ever-increasing problem. Generally, models for traffic flow in road networks are time-dependent and continuous, that is, they describe traffic by a continuum rather than as individual drivers or cars. These macroscopic models…

New research has shown how normally helpful brain cells can turn rogue and kill off other brain cells following injury or disease.Astrocytes have long been implicated in the pathology of a range of human neurodegenerative diseases or injuries including Alzheimer's, Huntington’s Parkinson’s disease, brain trauma and spinal cord injury.

According to a new study published in the journal Proceedings of the National Academy of Sciences, 35% of black carbon in the Russian Arctic originates from residential heating sources, 38% comes from transport, while open fires, power plants, and gas flaring are responsible for only 12%, 9%, and 6% respectively. These estimates confirm previous work for…

People think of corrosion as rust on cars or oxidation that blackens silver, but it also harms critical electronics and connections in solar panels, lowering the amount of electricity produced.“It’s challenging to predict and even more challenging to design ways to reduce it because it’s highly dependent on material and environmental conditions,” said Eric Schindelholz,…

A group of scientists is recommending giving the world’s nature reserves a makeover to defend not only flora and fauna, but people, too.Scientists in this week’s Proceedings of the National Academy of Sciences argue that the world’s protected areas such as nature reserves, traditionally havens for endangered animals and plants, can be made better if…
