How a popular antidepressant drug could rewire the brain

Prozac®, the trade name for the drug fluoxetine, was introduced to the US market for the treatment of depression in 1988. Thirty years later, scientists still don’t know exactly how the medication exerts its mood-lifting effects. Now, researchers report that, in addition to the drug’s known action on serotonin receptors, fluoxetine could rearrange nerve fibers…

Low VIT K may result in knee pain, disability or immobility

Low VIT K may result in knee pain, disability or immobility Low VIT K may result in knee pain, disability or immobility “older adults with low circulating vitamin K levels were nearly 1.5 times more likely to develop mobility limitation and nearly twice as likely to develop mobility disability compared to those with sufficient levels.…

Researchers teleport information within a diamond

Researchers from the Yokohama National University have teleported quantum information securely within the confines of a diamond. The study has big implications for quantum information technology — the future of how sensitive information is shared and stored. The researchers published their results on June 28, 2019 in Communications Physics. Source: Researchers teleport information within a…

Space station mold survives high doses of ionizing radiation

The International Space Station, like all human habitats in space, has a nagging mold problem. Astronauts on the ISS spend hours every week cleaning the inside of the station’s walls to prevent mold from becoming a health problem. New research being presented at the 2019 Astrobiology Science Conference, co-hosted by AGU and NASA June 24-28,…

Scientists track the source of the ‘Uncanny Valley’ in the brain

Scientists have identified mechanisms in the human brain that could help explain the phenomenon of the ‘Uncanny Valley’ — the unsettling feeling we get from robots and virtual agents that are too human-like. They have also shown that some people respond more adversely to human-like agents than others. Source: Scientists track the source of the…

Performance-enhancing bacteria may increase performance by 13%

Performance-enhancing bacteria may increase performance by 13% They pinpointed one specific group of bacteria, called Veillonella, that they found was enriched in the gut microbiome of Boston Marathon runners after after completing the 26.2 race and in an independent group of 87 elite and Olympic athletes after competitions. Veillonella bacteria isolated from marathon athletes and…

What made humans ‘the fat primate’?

How did humans get to be so much fatter than our closest primate relatives, despite sharing 99% of the same DNA? A new study suggests that part of the answer may have to do with an ancient molecular shift in how DNA is packaged inside fat cells, which curbed our body’s ability to turn ‘bad’…
