Between a rock and a hard place: how life survives under a glacier

How does microbial life manage to survive in subglacial environments over millions of years? New research from the University of Bristol has found that the grinding of bedrock by glaciers and ice sheets produces a continual supply of hydrogen gas, a ready source of energy (‘food’) for many microbes. This hydrogen is most likely formed when the highly reactive surfaces of freshly fractured silicate minerals react with and split water.

Neuropsychological effects of rapid-acting antidepressants may explain their clinical benefits, new research finds

Rapid-acting antidepressants, including ketamine, scopolamine and psilocybin, have been found to have immediate and lasting positive effects on mood in patients with major depressive disorder but how these effects arise is unknown. New research led by the University of Bristol explored their neuropsychological effects and found that all three of these drugs can modulate affective biases associated with learning and memory.

Diet in childhood linked to blood vessel damage in teenage years

Diets high in calories, fat and sugar in childhood can cause damage to blood vessel function, known to heighten the risk of early heart attacks and strokes, as early as adolescence according to research funded by the British Heart Foundation (BHF). The team behind the University of Bristol-led study, published in the British Journal of Nutrition today [10 January], say their findings highlight the importance of healthy eating habits throughout life to protect heart health.
