Nanoengineers can print 3-D microstructures in mere seconds Posted: 13 Sep 2012 01:27 PM PDT A novel technology can fabricate, in mere seconds, microscale three dimensional (3-D) structures out of soft, biocompatible hydrogels. The technology could lead to the ability to print biological tissues for regenerative medicine. Chen is able to print tissues that mimic nature's fine-grained details, including blood vessels, which are essential for distributing nutrients and oxygen throughout the body.

Home sweet lab: Computerized house to generate as much energy as it uses Posted: 13 Sep 2012 01:27 PM PDT The U.S. National Institute of Standards and Technology (NIST) has unveiled a new laboratory designed to demonstrate that a typical-looking suburban home for a family of four can generate as much energy as it uses in a year.

Do it yourself and save: Making equipment for the lab, in the lab Posted: 13 Sep 2012 11:11 AM PDT The open-source revolution is driving down the cost of doing science by letting researchers to make their own lab equipment.

Researchers look to alien soils for heat shield Posted: 13 Sep 2012 11:04 AM PDT An important test is coming up next week to see whether a heat shield made from the soil of the moon, Mars or an asteroid will stand up to the searing demands of a plunge through Earth's atmosphere. At stake is the possibility that future spacecraft could leave Earth without carrying a heavy heat shield and instead make one on the surface of another world and ride it home safely. The weight savings opens new possibilities ranging from using smaller rockets to carrying many more supplies on an exploration mission.

Boiling water without bubbles: Researchers engineer special surface, allowing water to boil without producing bubbles Posted: 13 Sep 2012 10:29 AM PDT Every cook knows that boiling water bubbles, right? New research turns that notion on its head. Scientists have shown how a specially engineered coated surface can create a stable vapor cushion between the surface and a hot liquid and eliminate the bubbles that are created during boiling.

Chemists develop nose-like array to 'smell' cancer Posted: 13 Sep 2012 10:23 AM PDT In the fight against cancer, knowing the enemy's identity is crucial for diagnosis and treatment, especially in metastatic cancers that spread between organs and tissues. Now chemists have developed a rapid, sensitive way to detect microscopic levels of many metastatic cell types in living tissue.

Scientists use sound waves to levitate liquids, improve pharmaceuticals Posted: 13 Sep 2012 09:35 AM PDT Scientists have been using an "acoustic levitator" to find new ways to achieve containerless drug processing.

Laser-powered 'needle' promises pain-free injections Posted: 13 Sep 2012 09:35 AM PDT From flu shots to immunizations, needle injections are among the least popular staples of medical care. A new laser-based system that blasts microscopic jets of drugs into the skin could soon make getting a shot as painless as being hit with a puff of air. The system uses a laser to propel a tiny, precise stream of medicine with just the right amount of force.

Computer program can identify rough sketches Posted: 13 Sep 2012 07:50 AM PDT Computer scientists have developed a new program that can recognize rough sketches in real time, something that up to now had been very difficult for computers to do. To make the program work, the researchers used 20,000 real sketches to teach the program how humans actually sketch objects.

Popularity versus similarity: A balance that predicts network growth Posted: 13 Sep 2012 06:19 AM PDT Do you know who Michael Jackson or George Washington was? You most likely do: they are what we call "household names" because these individuals were so ubiquitous. But what about Giuseppe Tartini or John Bachar? That's much less likely, unless you are a fan of Italian baroque music or free solo climbing. In that case, you would have heard of Bachar just as likely as Washington. The latter was popular, while the former was not as popular but had interests similar to yours. A new paper explores the concept of popularity versus similarity, and if one more than the other fuels the growth of a variety of networks, whether it is the Internet, a social network of trust between people, or a biological network.

Brighter future for carbon dots Posted: 13 Sep 2012 05:34 AM PDT Researchers have produced water-soluble carbon dots that selectively emit light across the entire visible range without any surface coating. The properties of these new C-dots make them ideal for a variety of bioimaging applications and for medical diagnostics.

Shattering glass cookware: New paper addresses causes; Margin of safety described as 'borderline' Posted: 12 Sep 2012 06:38 AM PDT In response to reports of explosive-like glass cookware failures, researchers applied basic materials engineering concepts to identify the causes. They found that current glass cookware sold in the United States is made of soda lime silicate glass rather than borosilcate glass used in the original Pyrex composition. They found that the soda lime silicate glass is much more susceptible to failure due to rapid temperature changes than borosilicate glass.
