The world population will hit 7 billion on Halloween this year, according to a guesstimate from the United Nations. So, should you be scared?
Extreme weather events over the past decade have increased and were “very likely” caused by manmade global warming, a study in the journal Nature Climate Change stated. Scientists at Germany’s Potsdam Institute for Climate Research used physics, statistical analysis and computer simulations to link extreme rainfall and heat waves to global warming. The link between…
So far our galactic adventures have included landing men on the moon, taking pretty pictures of Saturn, and roaming the surface of Mars. So what’s next on NASA’s to-do list? Perhaps snagging an asteroid to keep in our own backyard. Author Metanexus Editors
Gentle electrical zaps to the brain can accelerate learning and boost performance on a wide range of mental tasks, scientists have reported in recent years. But a new study suggests there may be a hidden price: Gains in one aspect of cognition may come with deficits in another. Researchers who study transcranial electrical stimulation, which…
Sometimes, finding nothing is just as good as finding something. Physicists have made the most sensitive measurements yet in the hunt for a rare event that could undermine the dominant theory of particle physics, and turned up zilch. The scientists, who are searching for a rumored particle decay process called “neutrinoless double-beta decay,” ran a…
The sought-after equanimity of “living in the moment” may be impossible, according to neuroscientists who’ve pinpointed a brain area responsible for using past decisions and outcomes to guide future behavior. The study, based on research conducted at the University of Pittsburgh and published in the professional journal Neuron, is the first of its kind to…
In recent years astronomers have extended their view almost to the very edge of the observable universe. With the venerable Hubble Space Telescope researchers have spotted a handful of galaxies so faraway that we see them as they appeared just 400 million years or so after the big bang. But even as astronomers peer ever…
