Fear and anger often lead us to take actions we later regret.</p><p>But a more recent line of research suggests there is much to be said for the intuitive wisdom of the body. According to mind-body oriented scholars such as Antonio Damasio, uncomfortable sensations that inhibit our normal thought patterns can sometimes provide valuable guidance.</p><p>A research team led by Utrecht University psychologist Denise de Ridder suggests these thinkers are on to something &mdash; at least when the unpleasant...</p> <a href="">More</a>By Tom JacobsWed, 29 Oct 2014 10:59:00 -0400Beware of Splenda: The backlash against artificial sugars<img src="" /></P><p>As a diet soda addict, I knew this day would come. The day when science showed me the error of my assumptions. The day that my brain's quest for a guilt-free sugar fix would slowly begin to die.</p><p>In the latest issue of the journal <em>Nature</em>, scientists report a startling finding. Artificial sweeteners like saccharin (used in the military's field rations), sucralose (Splenda), and aspartame (Diet sodas) changed the microbiome inside mouse intestines so dramatically that they induced hyperglycemia &mdash; glucose intolerance &mdash; the very syndrome that these fake sugars are marketed to prevent.</p>... <a href="">More</a>Marc AmbinderWed, 29 Oct 2014 08:42:00 -0400This celebrity scientist wants Germans to stop recycling. Here's why.<img src="" /></P><p><br /></p><p>BERLIN, Germany &mdash; Michael Braungart is in a hurry.</p><p>A former environmental activist who once scaled smokestacks to fight pollution for Greenpeace, the celebrity chemist has emerged over the past two decades as a dark horse in the race to find solutions for saving the planet.</p><p>Braungart wants to end the current drive for people to "reduce, reuse and recycle" goods in order to prompt the next industrial revolution. His core idea is for manufacturers and users to no longer "consume" raw materials that are turned into waste, but "borrow" them, a concept he calls cradle-to-cradle.</p><p>"It's really...</p> <a href="">More</a>By Jason OverdorfTue, 28 Oct 2014 09:07:00 -0400How quantum computing could change everything<img src="" /></P><p> <br /></p><p>The trend in computing for decades has been packing more power into smaller spaces &mdash; your smartphone, after all, is leagues ahead of the network of computers that sent Apollo 11 to the moon and back. But the next wave of computers, for some dreamers, gets really, <em>really</em> small, down to the quantum level. A quantum computer, essentially, is a way to harness quantum mechanics to process information. Its fundamental unit is called the qubit, analogous to the bit in conventional computers.</p><p><strong>What's it made of?</strong></p><p>A bit in an ordinary computer records one of two states, which we usually think of...</p> <a href="">More</a>By Roxanne PalmerTue, 28 Oct 2014 09:02:00 -0400These two studies should be a wake-up call to natural-childbirth extremists<img src="" /></P><p dir="ltr">There is a lot of guilt surrounding childbirth these days.</p><p dir="ltr">Many women, including actress Kate Winslet, are ashamed about having a C-section. Women who have opted for pain medication have reported feeling guilty about it. Medicalized births can even be a source of PTSD.</p><p dir="ltr">At the center of this guilt is a belief that doctors and hospitals can't be trusted. By doing what medical experts recommend, many think, a woman has somehow failed herself and her child. Indeed, alternative-birth advocates have long cited the high rate of infant mortality and C-sections as reasons to steer clear of a typical,...</p> <a href="">More</a>By <a href="/author/elissa-strauss" ><span class="byline">Elissa Strauss</span></a>Tue, 28 Oct 2014 07:02:00 -0400Why musicians are better multitaskers<img src="" /></P><p><br /></p><p>We all call it "multitasking," but psychologists insist that's a misnomer. Since we can't actually focus on more than one thing at a time, the skill is really "task switching" &mdash; the ability to alternate smoothly and easily between two sets of mental tasks.</p><p>New research from Canada suggests one group of people is able to do that better than the rest of us: trained musicians.</p><p>York University psychologists Linda Moradzadeh, Galit Blumenthal, and Melody Wiseheart report musicians appear to have "superior ability to maintain and manipulate competing information in memory, allowing for efficient...</p> <a href="">More</a>By Tom JacobsMon, 27 Oct 2014 13:01:00 -0400How you judge politicians' attractiveness, according to science<img src="" /></P><p><br /></p><p>Beauty, they say, is in the eyes of the beholdee's in-group.</p><p>At least, that's what they say if "they" means researchers interested in how we perceive political leaders. According to researchers at Cornell University's Lab for Experimental Economics and Decision Research, people seem to be judging the cover in part by the content of the book: Democrats find their political heroes more attractive than Republican leaders, and vice versa.</p><p>Curious to know, essentially, how hot for their leaders partisans and average citizens were, the lab's co-director, Kevin Kniffin, and colleagues conducted a...</p> <a href="">More</a>By Nathan CollinsFri, 24 Oct 2014 08:55:00 -0400Painting the universe's portrait<img src="" /></P><p><br /></p><p>Humans have long strived to describe the universe they find themselves in, whether they believed it was carried on the back of a giant turtle, shaped by an old bearded guy, or came into existence in a fiery explosion.</p><p>As part of this effort to make sense of the totality of reality, people have produced a stunning array of images representing the universe and celestial phenomena, using everything from paintbrushes to supercomputers. Filmmaker and author Michael Benson has collected 320 pages' worth of these artistic portraits of the universe, composed over a span of some 4,000 years, in his new...</p> <a href="">More</a>By World Science Festival StaffThu, 23 Oct 2014 16:15:00 -0400Can science fiction spur scientific innovation?<img src="" /></P><p><br /></p><p>Does science fiction help us innovate? According to Arizona State University's strange and strangely compelling Center for Science and the Imagination, the answer is, absolutely yes. The Center (yes, it's abbreviated CSI) has joint projects with organizations like IBM and the World Bank, and it was founded on the premise that imagination is an essential component of our society's greatest scientific and technological accomplishments. If we want to do big things, then we need to rev up our imaginations &mdash; with science fiction.</p><p>A perceived lack of imagination in our society prompted the creation...</p> <a href="">More</a>By Michael WhiteThu, 23 Oct 2014 09:33:00 -0400Why some men develop signs of pregnancy<img src="" /></P><p><br /></p><p>Harry Ashby, the 29-year-old security guard who was signed off work with morning sickness, cravings, a growing stomach and breasts during his girlfriend's pregnancy, was told he had Couvade syndrome.</p><p>Couvade is an involuntary manifestation of pregnancy in men with a partner who is expecting a baby &mdash; sometimes called "sympathetic pregnancy." It isn't a medically recognized physical or mental disorder, and it isn't explained by injury or illness.</p><p>A range of "pregnancy-related" physical and psychological symptoms include abdominal pain and bloating, back pain, pseudocyesis (euphemistically...</p> <a href="">More</a>By Arthur BrennanTue, 21 Oct 2014 08:44:00 -0400
