Diffuse optical tomography could offer a safer alternative to fMRI and PET scans (Photo: T...

When doctors want to monitor someone's brain activity, they generally use either functional magnetic resonance imaging (fMRI) or positron emission tomography (PET). One subjects the patient to strong magnetic fields, while the other involves radiation exposure. Scientists at Washington University in St. Louis, however, have recently had success using diffuse optical tomography (DOT). Although it may look kind of extreme, it basically just involves shining LEDs into the subject's head.  Read More

A vial of the clear hydrogel turns to a white semi-solid as it's heated to body temperatur...

In the field of regenerative medicine, one of the current areas of interest involves the use of scaffolding-like materials that a patient's own cells can be "seeded" onto. As the cells grow and populate the material, they gradually replace it, until all that remains is a solid piece of tissue or bone. Now, scientists at Houston's Rice University have taken that concept a step further, using a polymer that is liquid at room temperature, but that solidifies into a scaffold when injected into patients' bodies.  Read More

The 3D fruit printer uses spherification to create hybrid fruits, or to recreate existing ...

By now we're all quite used to seeing blended fruit juices such as banana-strawberry or apple-lime, but what about solid three-dimensional hybrid fruits that are made to order? Well, that's just what Cambridge, UK-based design company Dovetailed is promising, with its 3D fruit printer.  Read More

Scientists have created functioning human heart tissue that exhibits Barth syndrome  (Imag...

When we've previously heard about "organs on a chip," they've been miniature recreations of healthy organs. If they're being used for research into the treatment of health problems, however, then it only makes sense that those "organs" should have something wrong with them. With that in mind, a group of Harvard scientists have created the world's first lab-grown sample of functioning human heart tissue that has a cardiovascular disease.  Read More

An image captured using the new lens Night-vision security cameras could be getting a lot less costly, thanks to the discovery that their lenses can be made from silicon. Ordinarily, thermal infrared camera lenses are made from materials such as germanium and chalcogenide, which are much more expensive.  Read More

One of the three Lutra airboats used in the study

Although hippos may look slow and docile, they're actually very aggressive, killing more people every year than any other large African animal. So, it would follow that you wouldn't want to swim anywhere near them. That's why when researchers from Yale University and the Cary Institute of Ecosystem Studies wanted to study the effects of hippo dung on water quality in Kenya's Mara River, they sent in three autonomous air boats instead of people. To help those boats blend in, they were dressed up as crocodiles.  Read More

A few of the bikes that were featured at Charged Up

As many readers are no doubt already aware, last Thursday we attended the Charged Up e-bike media event at the Crystal Springs Resort in northern New Jersey. The day was mainly a chance for a select group of journalists to chat with representatives from a number of electric bike companies, and to ride some of their bikes around the resort grounds. While we've already profiled a few of the stand-outs, here's a quick look at some of the other e-bikes that caught our eye.  Read More

The iStick features both Lightning and USB connectors

Although the iPhone and iPad may indeed pack a whole plethora of features, they still lack a plain ol' USB port. This means that they can't share files with a Mac or PC via a regular flash drive. The iStick, however, isn't regular. According to its creators, it's the world's first Lightning-to-USB flash drive.  Read More

The iZip E3 Town:exp on display at the Charged Up electric bike media event in New Jersey

In order for an electric bike to stand out from the pack, it helps if it offers unique features such as light weight or the ability to fold. Of the e-bikes that we saw at last week's Charged Up event, however, one of our faves is a little number that isn't particularly remarkable in any one way. It's the iZip E3 Town:exp, and it simply manages to pack several good things into a small package.  Read More

Although you'll probably never make it to outer space, Swiss Space Systems (S3) is at least trying to move the zero-gravity experience a little closer to reality for the average person. This week, the company announced its plans to start offering what it claims will be the world's cheapest weightlessness-inducing flights, from 15 international locations.  Read More
