• People Are Terrible at Spotting Fake Photos

  20-07-2017 23:36 via feedproxy.google.com
  
  We exist in a veritable flood of digital images, with at least 350 million a day uploaded to Facebook alone, and odds are significant number of those images are fake. And, given results from a recent study, most people can't tell the difference.Can you identify the part of the top photo that's been altered? Don't worry, we'll tell you later.Psychologist Sophie Nightingale and her colleagues at the University of Warwick used photo-editing software to doctor real-world photos in ways t

• Pulses of electrons manipulate nanomagnets and store information

  20-07-2017 21:49
  
  Magnets and magnetic phenomena underpin the vast majority of modern data storage, and the measurement scales for research focused on magnetic behaviors continue to shrink with the rest of digital technology. Skyrmions, for example, are a kind of nanomagnet, comprised of a spin-correlated ensemble of electrons acting as a topological magnet on certain microscopic surfaces. The precise properties, like spin orientation, of such nanomagnets can store information. But how might you go about moving o

• If You Could Dig a Hole Through The Earth, Here's Where You'd Pop Out

  Almost every child, shovel in hand, is struck by a tempting thought. What if I just kept digging and popped out on the other side of the world? The imagination conjures a muddy face emerging in the middle of a Shaolin temple or some such, China being the nominal "other side of the world" to Americans.That image is wrong, unfortunately, as a map showing the Earthly antipodes makes clear.

• Ancient Italian fossils reveal risk of parasitic infections due to climate change

  20-07-2017 21:45
  
  In 2014, a team of researchers led by a paleobiologist from the University of Missouri found that clams from the Holocene Epoch (that began 11,700 years ago) contained clues about how sea level rise due to climate change could foreshadow a rise in parasitic trematodes, or flatworms. The team cautioned that the rise could lead to outbreaks in human infections if left unchecked. Now, an international team from Mizzou and the Universities of Bologna and Florida has found that rising seas could be d

• NASA looks to solar eclipse to help understand Earth's energy system

  It was midafternoon, but it was dark in an area in Boulder, Colorado on Aug. 3, 1998. A thick cloud appeared overhead and dimmed the land below for more than 30 minutes. Well-calibrated radiometers showed that there were very low levels of light reaching the ground, sufficiently low that researchers decided to simulate this interesting event with computer models. Now in 2017, inspired by the event in Boulder, NASA scientists will explore the moon's eclipse of the sun to learn more about Earth's

  Things aren't looking good for Africa's iconic wildlife. Already, many species are threatened by human activities and habitat loss. Even species once thought to be resilient, like giraffes, are suddenly struggling. Just earlier this week, scientists reported that aardvarks, one of sub-saharan Africa's most successful and adorable insect-eaters and essential ecosystem engineers—face severe declines and even extinction as rising temperatures and declining rainfall dry out the continent.

  A study in fruit flies suggests that existing approaches to gene drives using CRISPR/Cas9, which aim to spread new genes within a natural population, will be derailed by the development of mutations that give resistance to the drive. Jackson Champer, Philipp W. Messer, and colleagues at Cornell University in Ithaca, New York report these findings July 20, 2017 in PLOS Genetics.

• Experiment finds evidence for the Majorana fermion, a particle that's its own antiparticle

  20-07-2017 20:00
  
  In 1928, physicist Paul Dirac made the stunning prediction that every fundamental particle in the universe has an antiparticle - its identical twin but with opposite charge. When particle and antiparticle met they would be annihilated, releasing a poof of energy. Sure enough, a few years later the first antimatter particle - the electron's opposite, the positron - was discovered, and antimatter quickly became part of popular culture.

The glass is covered with hydroxyl (-OH) groups that can lose a proton - a much-studied chemical reaction that is important in geology, chemistry and technology. A 100-micron long capillary displayed a remarkable spread in surface OH bond dissociation constant of a factor of a billion
