This latest search for electron decay was made using the Borexino detector, which is designed primarily to study neutrinos. It is located deep under a mountain at the Gran Sasso National Laboratory to shield it from cosmic rays and comprises 300 tonnes of an organic liquid that is viewed by 2212 photomultipliers.
There’s no known cure for the common cold, but receiving multiple tattoos can strengthen your immunological responses, potentially making you heartier in fighting off common infections, according to research. However, receiving a single tattoo can, at least temporarily, lower your resistance.
I can tell you that gravitational waves are effectively ripples in the fabric of spacetime, spreading much like ripples on the surface of a pond do when a rock is tossed into the pond. They were predicted about a century ago by Einstein as part of his Theory of Relativity, although apparently he didn’t think we’d ever have the technology to detect them. For measurable gravitational waves to even make it to earth, a massive ripple has to be started by an enormous release of energy, such as what happens during the collision of two black holes.
In what may or may not have been a close fly-by, asteroid TX68 flew by earth somewhere between 15,000 miles and 3,000,000 miles away on Monday night. First discovered Oct. 6th, 2013, the asteroid flew by then with little data collected. This made the determination of how close the current fly-by would be rather difficult, thus the broad range of distance from Earth. Scientists hope to have a better understanding of the asteroid’s path in space by the next time it comes around.
“There is no concern whatsoever regarding this asteroid — unless you were interested in seeing it with a telescope,” Paul Chodas, manager of CNEOS, assured worried Earthlings in February.
NASA has not yet determined how close TX68 came to Earth, but Rob Landis, a program officer at NASA headquarters, said if the night sky was clear in the west and over Hawaii, NASA should be able to “nail down the orbit.”
The following study looked important to me, as I suffer from a general anxiety disorder:
In a study of anxiety sufferers, scientists have learned that people with anxiety likely perceive the world differently. By a series of tests involving sound and financial gaming, scientists examined the perceptions and reactions of people with and without generalized anxiety. There findings suggest that those with anxiety are less able to differentiate between new stimuli than those without. Verbosely (with reference notes removed here):
Recent studies have suggested that overgeneralization can underlie anxiety disorders. In this account, following formation of association between a stimulus and an aversive outcome, stimuli that are only somewhat similar to the original stimulus would still elicit increased anxiety in affected individuals. In an unsafe environment full of complex stimuli where the original stimulus is still dangerous, this is an extreme but rational strategy.
In practical terms, what happened was sounds were played, and a certain sound resulted in increased financial standings in a fictionalized economy. A different sound resulted in decreased financial standings. A third sound was standing neutral, with no increase or decrease associated. Later, outside the game, similar sounds were used, and those with anxiety had greater reactions to the sounds similar to those which were used within the game.
