How injectable nanogel could help fight diabetes

For diabetics who have to constantly manage their blood-sugar levels, insulin works. The problem is, many people with Type 1 diabetes have to prick their fingers multiple times a day to monitor their levels, and inject themselves with insulin when those levels are too high. And they don't always administer the right amount at the right time.

Researchers at the Massachusetts Institute of Technology and Boston Children's Hospital hope to automate insulin delivery with a novel nanotech approach that involves injecting a gel that detects blood-sugar levels and secretes insulin when needed -- with a single injection doing do the trick for as many as 10 days.… Read more

3D scanning shows a butterfly's metamorphosis

Thanks to the magic of dissection, we have a pretty good idea of the changes that occur when a caterpillar spins its chrysalis and enters its metamorphosis -- the developmental stage that sees it move from the juvenile larval stage to the gorgeous adult life of a butterfly.

However, as you might have already guessed, dissection destroys the specimen, meaning that researchers are unable to follow the full development of a creature. We do know that the caterpillar will use enzymes to break down some of its proteins to reform; Scientific American called this a cocoon full of "caterpillar soup." However, scientists have performed research revealing that while some breakdown occurs, the idea of caterpillar soup is mostly wrong (but still gross).

Using micro-computed tomography, or micro-CT scanning, which uses X-ray imaging to re-create 3D cross-sections of the scanned object, Tristan Rowe and Russell Garwood from the U.K's University of Manchester and Thomas Simonsen from London's Natural History Museum have discovered exactly what happens to a painted lady butterfly inside the chrysalis. … Read more

NASA's Kepler telescope crippled by technical failures

The Kepler space observatory has been a source of great wonder since it first launched in 2009. It has turned its eyes out into the great vastness of space and seen new planetary systems and potentially life-supporting planets. The telescope's original 3.5-year mission was extended into 2016, but that may now come to a halt as serious technical issues take a toll.

Kepler is able to look out in certain directions thanks to four reaction wheels that are used to point the spacecraft. As of Wednesday, two out of four reaction wheels have failed.… Read more

First wind-current power system to be installed off Japan's coast

We may be closer to harnessing the power of the sea and air. The world's first hybrid wind-current power generation system will be installed off the coast of Japan later this year.

The Savonius Keel & Wind Turbine Darrieus (SKWID) power generation system being developed by Mitsui Ocean Development & Engineering Company (Modec) is a floating system that shares a vertical floating axis. On the company's Web site (PDF), Modec says the concept will generate double or more power from the same sea surface area as a conventional wind turbine. … Read more

$325,000 stem cell hamburger to be eaten soon

The race for a lab-grown meat alternative has been on for years. Modern Meadow, for example, has gone after a type of 3D-printed meat using bioprinting techniques. Dutch tissue engineer Mark Post is using stem cells to make a lab-grown hamburger, one that may be actually going down someone's gullet very soon.

Post's Cultured Beef Project has been in development at Maastricht University in the Netherlands for some time thanks to $325,000 in funding from an anonymous donor. Cow muscle stem cells are grown into miniscule strips of tissue. Each strip can take several weeks to grow. It takes 20,000 of these to make a single hamburger. It's a time-consuming and expensive product at this stage of the project.… Read more

Having made the ISS cool again, Hadfield returns to Earth

The one-man media machine has landed.

Canadian astronaut Chris Hadfield returned to Earth in a Soyuz descent capsule after his six-month stint on the International Space Station, during which he became an Internet sensation.

Along with ISS crewmates American astronaut Tom Marshburn and Russian cosmonaut Roman Romaneko, Hadfield was extracted from the capsule in the Kazakhstan morning (around 10:31 p.m. ET) following a smooth descent.

Hadfield, the last to emerge from the capsule, waved and gave a thumbs-up once he was propped in a chair in the sunshine.

The trio is to be whisked off by helicopter to … Read more

Techno-circus brings robots, lasers to the big tent

Step right up, kiddies, the carnival is coming to town! And this time, it's bringing robots and lasers.

Well, it will be if the STEAM Carnival successfully reaches its Kickstarter goal and hits the highway with all manner of amusing geeky hijinks under its big tent. Think Maker Faire meets Burning Man, with a decidedly less naked, more kid-friendly slant. The goal is to not only get youngsters pumped about STEM (Science, Technology, Engineering, and Math), but to warm them up to STEAM (Science, Technology, Engineering, Art, and Math).

"Our culture isn't doing enough to get kids interested in STEAM," say the creatives behind Two Bit Circus, a collective of builders, inventors, developers, and makers behind STEAM Circus. (They also helped create the wacky Rube Goldberg machine in OK Go's "This Too Shall Pass" video.) The carnival's advisory board also brings some serious geek cred to the proceedings in the form of MythBuster Grant Imahara; Brian Fargo, creator of the video game Bard's Tale; and Nolan Bushnell, founder of Atari and father of Brent Bushnell, one of STEAM Carnival's masterminds.

3D holograms show if baby's smiling in the womb

Remember back in the olden days, when you had to wait till your baby came out of the womb to start determining whose nose and chin it had?

Pioneer, maker of speakers, receivers, and headphones, is moving into the in-utero-baby-picture realm with 3D holograms that give a remarkably detailed look at an infant's early visage.

The company does that using a full-color hologram printer. The device, which fits into a briefcase, can record a full color card-size hologram in 120 minutes, and a single-color hologram in 90 minutes. … Read more

Time-lapse images let you witness 28 years of Earth's changes

A newly released series of dramatic time-lapse satellite images, available at Google's Timelapse Web site, shows just how quickly the world's landscapes have changed in the last 28 years.

The pictures, captured by the series of Landsat satellites and released in conjunction with the U.S. Geological Survey, NASA, and Time magazine, show several startling examples of how humans and natural processes have changed Earth from 1984 to 2012. You'll see the depressing decline of the Columbia Glacier in Alaska, the blossoming of Dubai's epic cityscape, and Las Vegas' urban explosion. There's also an alarming look at the deforestation occurring in the Brazilian Amazon forest. … Read more

Four iOS weather apps that exude elegance

It wasn't very long ago that for a developer to make a successful weather app, it had to have the most information possible. This meant developers would compete to pack tons of graphs, maps, diagrams, written forecasts -- and even forums where people could talk about weather -- into busy, confusing apps that tried to cover it all. But what you ended up with were long, listlike menus when the only information you probably wanted was what the weather might be like for the weekend.

Don't get me wrong, the feature-packed weather apps have their place, particularly when … Read more
