| Fibre-optics used to take the temperature of Greenland Ice Sheet Posted: 15 May 2021 06:11 AM PDT Scientists have used fibre-optic sensing to obtain the most detailed measurements of ice properties ever taken on the Greenland Ice Sheet. Their findings will be used to make more accurate models of the future movement of the world's second-largest ice sheet, as the effects of climate change continue to accelerate. |
| People at high genetic risk for colorectal cancer benefit more from lifestyle changes Posted: 15 May 2021 06:11 AM PDT People with a high polygenic risk score for colorectal cancer could benefit more at preventing the disease by leading healthy lifestyles than those at lower genetic risk, according to a new study. |
| Virtual reality warps your sense of time Posted: 14 May 2021 10:42 AM PDT Psychology researchers found that playing games in virtual reality creates an effect called 'time compression,' where time goes by faster than you think. The research team compared time perception during gameplay using conventional monitors and virtual reality to determine that this effect is uniquely linked to the virtual reality format. |
| Our dreams' weirdness might be why we have them, argues new AI-inspired theory of dreaming Posted: 14 May 2021 10:42 AM PDT Why we dream is a divisive topic within the scientific community, and the neuroscience field is saturated with hypotheses. Inspired by techniques used to train deep neural networks, a neuroscience researcher argues for a new theory of dreams: the overfitted brain hypothesis. The hypothesis suggests that the strangeness of our dreams serves to help our brains better generalize our day-to-day experiences. |
| Epigenetic changes drive the fate of a B cell Posted: 13 May 2021 02:35 PM PDT B cells are the immune cells responsible for creating antibodies, and most produce antibodies in response to a pathogen or a vaccine. A small subset of B cells instead spontaneously make antibodies that perform vital housekeeping functions. Understanding how epigenetics spur these differences in such similar cells is an important fundamental question in immunology. |
