People with epilepsy were once thought to be possessed by demons or evil spirits. Dubbed "the sacred disease," epilepsy was profoundly misunderstood for centuries, even after the disorder was explained to be of human origin. So why is it, so many years later, that epilepsy is still not fully understood? And why is there still so much stigma attached to a disorder which affects approximately one i

The quest to create affordable, durable and mass-produced 'smart textiles' has been given fresh impetus through the use of the wonder material Graphene.
That quantum mechanics is a successful theory is not in dispute. It makes astonishingly accurate predictions about the nature of the world at microscopic scales. What has been in dispute for nearly a century is just what it's telling us about what exists, what is real. There are myriad interpretations that offer their own take on the question, each requiring us to buy into certain as-yet-unverifi
When the creators of the long-running ABC sitcom The Middle , about a middle-class family living in Indiana, were coming up with the show's aesthetic, there was one prop they knew they had to have, to give the Hecks' family home genuine Midwestern flavor: a statue of a concrete goose to keep on their porch. And outfits to dress it up in. "Our showrunners are natives of Indiana, and they gave me g

We've sent numerous missions into space to study the Sun; past and present solar explorers include ESA's Proba-2 (PRoject for OnBoard Autonomy 2) and SOHO (SOlar Heliospheric Observatory) probes, NASA's SDO and STEREO missions (the Solar Dynamics Observatory and Solar Terrestrial Relations Observatory, respectively), and the joint NASA/ESA Ulysses mission. However, most of these spacecraft have fo
In the next decade, NASA aims to launch humankind toward the moon and on to Mars—a monumental step in crewed space travel. Such a journey is filled with challenges and perils, not unlike those faced by the first explorers to cross the ocean. However, instead of stormy seas, these explorers will set sail amid the hazards of the heliosphere—the magnetic environment emanating out from the sun and enc
While progress has been made, improvements to companies' anti-bribery and corruption strategies are still needed, according to the 2018 Global White Collar Crime Survey, which has been launched by The University of Manchester and global law firm White & Case LLP.
On Sunday, Nov. 25, the scientist He Jiankui claimed the birth of the world's first genetically engineered children: twins, created by IVF, their DNA altered at fertilization. Changes like these, because they're inheritable – "editing the germline" – are widely prohibited by law and avoided by scientific consensus. If He really did this, it's a very big step across a very bright line.

Most stars with the mass of the sun or larger have one or more companion stars, but when and how these multiple stars form is one of the controversial central problems of astronomy. Gravity contracts the natal gas and dust in an interstellar cloud until clumps develop that are dense enough to coalesce into stars, but how are multiple stars fashioned? Because the shrinking cloud has a slight spin,
It seems new action to tackle plastic pollution is announced every week, from the 5p plastic bag charge to governments debating a tax on plastic packaging. Businesses are also showing their green credentials as major supermarkets pledge to reduce plastic packaging alongside some multinational companies.
When people think of coral reefs, they typically picture warm, clear waters with brightly colored corals and fishes. But other corals live in deep, dark, cold waters, often far from shore in remote locations. These varieties are just as ecologically important as their shallow water counterparts. They also are just as vulnerable to human activities like fishing and energy production.

Almost 90 years ago on a freezing January morning, the keepers of the Stockholm Zoo in Sweden discovered a dead seal pup in their seal pond. The pup was immediately recognized as a bastard—a hybrid between species that should not interbreed. Only two grey seal males and one ringed seal female, species belonging to different mammalian genera, were housed in the pond. The hybrid appeared to carry a
Curiosity woke up to Mr Rogers' "Please would you be my neighbour" this morning to welcome InSight, and then got busy at the Highfield drill site. Curiosity will dump the Highfield sample, which requires several MAHLI looks and an APXS operation, but the plan also requires swinging the arm out of the way so other instruments can have their unobscured look at the dump pile.

In contrast, in situ observations with spacecraft provide microscopic information of phenomena such as the Earth's magnetosphere, but it is difficult to obtain global informatio
During a recent shower, I grabbed my bottle of body wash—which smells like lavender and has "relaxing" properties—and squeezed. It was dead empty. This left me with the backup plan many girlfriends know well: using your boo's "manly" body wash. You've seen it—dark gray bottle, sometimes with grippy nubs on the side. It gets you "deep clean," like you're polishing a rim wheel rather than scrubbing
Emile Ratelband, 69, argued that his age was causing him to struggle to find work and love A Dutch court has rejected the request of a self-styled "positivity guru" to shave 20 years off his age, in a case that drew worldwide attention. Last month, Emile Ratelband asked the court in Arnhem to formally change his date of birth to make him 49. He said his official age did not reflect his emotional

Problem solving doesn't have to involve numbers. Sometimes it just involves connecting dots between markets, and simple experiments based on data. These tweaks can make huge differences in people's lives. And anyone can do it, as social design can life entire communities. People who participate in social design learn how to apply it in the future, making social design a learnable and transferable

The House Democrats preparing to lead their own Russia probes appear to be turning their attention from possible collusion between the 2016 Trump campaign and Russian intelligence to potential Russian leverage over the president. The turning point came last week when Michael Cohen, Trump's former personal lawyer and fixer, pleaded guilty to lying to Congress about the Trump Organization's dealing
On a Wednesday morning in the United States Senate in February 1984, I was voting on President Ronald Reagan's plan to renew funding for the B-1 bomber, as I recall. The vice president was in the Presiding Officer's chair to cast the tiebreaker if necessary. George H. W. Bush beckoned to me as the clerk was calling the roll. The night before, my campaign for the Democratic nomination for presiden
John Kasich, the stalwart never-Trumper who says he may or may not run for president in 2020—maybe as a Republican challenging Donald Trump or maybe as an independent, because all options are open unless they're not—stopped in Philadelphia on Friday to practice his Art of the Tease. "As for me and what I'm going to do," he riffed during a nonpartisan forum, in his usual free-form manner, "I've be
Senator Jesse Helms of North Carolina opposed the Civil Rights Act , calling it "the single most dangerous piece of legislation ever introduced in the Congress." He opposed the Voting Rights Act.

Lizards in the eastern US are adapting to invasive fire ants—which can bite, sting, and kill them—in unexpected ways. The changes reverse geographical trends in behavioral and physical traits for avoiding predators. "Rapid environmental change, be it from changing climate or the introduction of invasive species, is putting a lot of pressure on native species," says Christopher Thawley, graduate s
Forearm arteries are more effective in coronary bypass surgery than the commonly used leg vein, a new study shows. In around 95 percent of bypass operations globally, surgeons still use veins from the legs, in combination with one of the chest wall arteries. And that's despite the fact that half of veins used in heart bypasses become completely blocked within 10 years of surgery. Arms and hands c
