How To Give A Mouse EbolaIf you give a lab mouse the mouse version of Ebola, it will die. But not in the same way humans with Ebola do. Lab mice infected with Ebola don't get hemorrhagic fever. They don't form tiny clots ... More >
What the Heck is a Co-Robot?When humans finally set foot on an alien world, they’ll be joined by robots. That’s not a bold prediction. It’s a statement of the obvious. Machines have already beat us to Mars ... More >
Interstellar Travel Won't Look Like The MovieChristopher Nolan's Interstellar imagines a human journey to planets beyond our star. But that kind of trip would seem impossible in today's terms. Fortunately, a DARPA-funded task ... More >
Despite my fondness for (and previous career in) computer troubleshooting, I find myself at sea when it comes to dealing with my car. But fortunately pretty much every car has a computer in it these days, and that onboard system can provide a first step to diagnosing a problem—all you need is the right tool.
Based at times in Area 51, the U-2 spyplane tested the very limits of human endurance and Cold War technology when it first flew in 1955. Pilots would fly the high-altitude spy craft at above 70,000 feet for hours at a time, taking photos of developments below. One such flight revealed the buildup of Soviet nuclear missiles in Cuba, and sparked the Cuban Missile Crisis. With the advent of drones, and specifically the long-endurance high-altitude Global Hawk, the U-2's days in service might be numbered. A plan by Lockheed wants convert the venerable spy plane of the past into a modern surveillance robot of the future.
Charles Darwin may be a household name now, but we haven't always had the theory of natural selection. On November 24, 1859, he published On the Origin of Species as a culmination of nearly three decades of research after his journey on the H.M.S. Beagle. Happy 155th anniversary of On the Origin of Species!
It's no accident that turkeys have more than doubled in size over the past 80 years—bigger is better, at least when it comes to the Thanksgiving table. But decades of farmers raising increasingly engorged turkeys isn't just bad for the birds, which may grow so large they can't even stand. Breeding focused on extreme muscle growth has led to an increasing number of turkeys falling victim to muscular and heart disease. The same practices lead many turkeys provide low-quality or otherwise unsavory meat. But a team of scientists believes they can reverse the unhealthy trend—with data they're collecting through genome sequencing.
On hot vents deep underneath the Atlantic and Pacific oceans, there lives something unusual: a gene that fights bacteria. The gene belongs to a microscopic organism, scientifically named Aciduliprofundum boonei, that lives in the extreme environments atop undersea thermal vents all over the world.
Robots are getting better all the time. They can mix drinks, explore other planets and even adapt to new situations. And they're not done yet. In a new paper published this week in Nature Geoscience, researchers describe using an autonomous underwater vehicle called SeaBED to map the underside of sea ice in Antarctica.
Glaciers are having a hard time all around the world. A new book outlines the findings of a years-long effort by researchers and research groups across the world. Titled Global Land Ice Measurements from Space (GLIMS), the book isn't going to hit bestseller lists anytime soon (it's a scientific tome, geared towards professionals), but it is the first truly comprehensive look at the state of the glaciers all over the globe. And that state is... not good.
Behold the fiery sphere of pain in the heavens! No, not the sun, this one is much, much closer to Earth, and much stranger still. Aboard the International Space Station, scientists have an electromagnetic levitator that lets them suspend a sphere of liquid metal in place. Why? To observe how it cools when it's free of a container or constraints like the strong gravity on Earth.
Remember that uncle who convinced you that your nose was actually in his hand? Or your conviction that you definitely heard reindeer hooves on the rooftop? Kids are gullible – at least that's the conventional wisdom. But new research pinpoints the time that a child's sense of truth and fiction becomes acute: around age 5.
By the end of the year, nearly 3 billion people in the world will have Internet access, according to the latest annual Measuring the Information Society (MIS) Report from the International Telecommunications Union (ITU). That's an increase of 6.6 percent over the previous year, continuing a steady trend upward that's been in place for the last decade.
