Whether we are searching the cosmos or probing the subatomic realm, our most successful theories lead to the inescapable conclusion that our universe is just a speck in a vast sea of universes.
Fool me once, shame on you. Fool me twice, shame on my parahippocampal gyrus. Scientists at the Virginia Tech Carilion Research Institute have found that suspicion resides in two distinct regions of the brain: the amygdala, which plays a central role in processing fear and emotional memories, and the parahippocampal gyrus, which is associated with…
It’s been called the “holy grail” of brain research and now, it may have been found. Scientists in the U.S. say they have developed a way to detect the concussion-related brain disease called CTE, or chronic traumatic encephalopathy, in living athletes. Until now, the disease, which brings on dementia, depression and personality changes, could only…
The mysterious common ancestor of all life on Earth may have been more complex than before thought—a sophisticated organism with an intricate structure, scientists now suggest. Author Metanexus Editors
Given the same raw materials, Mars would have been a better host for life to arise than Earth, which some scientists believe was too flooded for the chemistry of life to gain a toehold. Without at least occasional dry land, the chemistry needed to get life started doesn’t work very well because the molecules to…
Astronomers have discovered what they believe to be a rogue planet floating through space without a star. The super-Jupiter, called CFBDSIR2149, has a mass four to seven times that of our own gas giant, and is probably a scorching 800 or so degrees Fahrenheit. It appears to sit in a moving group of stars that,…
For the last 15 years, Kaptchuk and fellow researchers have been dissecting placebo interventions—treatments that, prior to the 1990s, had been studied largely as foils to “real” drugs. To prove amedicine is effective, pharmaceutical companies must show not only that their drug has the desired effects, but that the effects are significantly greater than those…
