Scientists have long tried to explain the origin of a mysterious, large and anomalously cold region of the sky. In 2015, they came close to figuring it out as a study showed it to be a “supervoid” in which the density of galaxies is much lower than it is in the rest of the universe. However, other studies haven’t managed to replicate the result.
Low energy efficiency is already a major problem for petrol and diesel vehicles. Typically, only 20% of the overall well-to-wheel energy is actually used to power these vehicles. The other 80% is lost through oil extraction, refinement, transport, evaporation, and engine heat. This low energy efficiency is the primary reason why fossil fuel vehicles are emissions-intensive, and relatively expensive to run.
We are currently experiencing unique circumstances. Never before has such a diverse group of people (rich, poor, old, young, happy, unhappy, healthy, unhealthy male, female, etc.) been confronted with a prolonged deficit of physical contact. What are the effects of this phenomenon on our mental well being? Researchers aim to answer this question in a new study.
“Please refrain from hand shaking,” read a sign at an event in London I recently attended. Despite increasing anxiety about coronavirus, for many of us, it was the first time we had encountered such a request. Underneath the words was a small image of two disembodied hands shaking, surrounded by a red circle struck through with a diagonal line.
