Best of Last Week: Questioning Higgs finding, possible alternative to antibiotics and reversing diabetes in mice
In other news, researchers working to solve the problem of growing resistance to antibacterial agents have found a possible alternative to antibiotics—artificial nanoparticles made of lipids that serve as decoys, attracting harmful bacteria and preventing them from attacking their actual target. Equally pressing is a better understanding of what is happening to our world as global warming continues unabated. Researchers at Berkeley identified a new driver behind Arctic warming—turns out the open ocean is far less efficient at emitting in the far-red spectrum than is ice, which means the Arctic Ocean traps more heat than has been thought.
In news from space, a team of astronomers believe they have solved the mystery of the bizarre object at the center of our galaxy—they think it's a pair of binary stars. Meanwhile NASA's Curiosity rover found a mineral match—showing that measurements taken from a distance match those of real minerals found on Mars. There was big news in biology as well, as a drug being tested in a clinical trial was shown to completely reverse diabetes in human islets and mice. More research will have to be done, of course, but thus far, the researchers report that the drug looks promising.
And finally, for those who have been wondering, researchers have found that those who adhere to the Mediterranean diet are likely to see lasting health benefits—they found that the diet led to improved blood flow to cells lining blood vessels, for up to a year after the diet was stopped—an indicator of overall general good health.
