(鶹Ժ)—It was a big week for physics. First, a trio of researchers proposed —in alternative theories of cosmology where it has been theorized that time and space can vary. Also, another team showed that —this describes conditions in which quantum correlations can be "frozen" in a constant state and remain that way in the presence of noise. Meanwhile another team suggested that —the hypothetical form of matter, the researchers suggest, could play a key role in mediating superconductivity.
Also, a team of astrophysicists working at the DOE's Fermilab suggested that —they are working with equipment capable of sensing gravitational waves at frequencies in the range of a million cycles per second. Also, work by two different teams suggested that —new data has come to light indicating that supernovae used to measure distances in the universe are more diverse than thought.
In other news, researchers at Stanford University have developed —they say it is less expensive, too. Meanwhile another team at Virginia Tech announced a new discovery that may be —a new way to create fuel cells using a biological method.
A team of bio-researchers discovered a master protein that enhances learning and memory—similar, they say, to other proteins that allow for enhanced physical abilities. And another team has , which portends a time in the near future when computers may be embedded in virtually everything around us.
And finally, for those people worried about losing their hair as they age, —they found that plucking hair in a certain pattern on mice induced new growth in the surrounding area—evidence of environmental circumstances causing the body to react in unpredictable ways.
