In study, acetaminophen makes risky moves seem less dangerous
While acetaminophen is helping you deal with your headache, it may also be making you more willing to take risks, a new study suggests. People who took acetaminophen rated activities like “bungee jumping off a tall bridge” and “speaking your mind about an unpopular issue in a meeting at work” as less risky than people…

Mealworms can compost styrofoam
Within our living systems, we have been raising several types of mealworms in order to compost polystyrene (styrofoam). We recently came across the study by 2015 Standard University that confirms our suspicions that they are indeed turning styrofoam into usable organic matter! Their notes are not m

Mouse studies show gene therapy can cause big drop in latent herpes infections
Improved gene therapy techniques cleared up to 95 percent of latent herpes virus in mice. Human trials? At least 3 years away. Fred Hutch virologist Dr. Keith Jerome hopes this study "opens up the idea that we can start thinking about cure, rather than just control of the virus."

RNA Memory Hypothesis
There’s an old theory that memory is actually encoded in part in RNA. The argument is pretty simple: there’s no obvious way for all that sensory data to be captured in synapses as long …

Physicists Magnetize a Material with Light
MIT physicists created a long-lasting magnetic state in a material, using only light. The results provide a new way to control and switch antiferromagnetic materials, which are of interest for their potential to advance information processing and memory chip technology.

Is Ego-Depletion a Replicable Effect?
Abstract It has been a common practice in social psychology to publish only significant results. As a result, success rates in the published literature do not provide empirical evidence for the existence of a phenomenon. A recent meta-analysis suggested that ego-depletion is a much weaker effect than the published…
