December 5, 2012

Objet1000_Cart_RacingCar-h-res-1

The 3-D printing industry is on track to be a $3.1 billion business by 2016 and the innovations on display this week at Euromold, a manufacturing trade show, show its foundation is growing — both in revenue and in physical print size, Wired News reports.

Objet 1000

The big news out of Euromold is the new Objet 1000 3-D printer,… read more

The world’s deadliest distinction: why aren’t the oldest living people getting any older?

July 27, 2011

Jeanne Calment at age 121

Raising the upper bounds of the human lifespan is turning out to be trickier than increasing the average person’s life expectancy. In the past few years, the global count of supercentenarians — people 110 and older — has leveled off at about 80.

And the maximum age hasn’t budged. Just seven people whose ages could be fully verified by the Gerontology Research Group have ever made it… read more

Nanoparticles loaded with bee venom kill HIV

March 11, 2013

Nanoparticles (purple) carrying melittin (green) fuse with HIV (small circles with spiked outer ring), destroying the virus’s protective envelope. Molecular bumpers (small red ovals) prevent the nanoparticles from harming the body’s normal cells, which are much larger in size. (Credit:

Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in St. Louis have shown.

The finding is an important step toward developing a vaginal gel that may prevent the spread of HIV, the virus that causes AIDS.“Our hope is that in places where HIV is running rampant, people… read more

TASER International has announced new kind of camera called AXON flex, to be worn by police officers.

The half-ounce unit is about the size of a cigar stub and clips on to a collar or sunglasses of an officer. It can record two hours of video during a shift. The information is transferred by a docking station to a local machine, and eventually stored… read more

CISPA, the Senate, and what should be done

April 30, 2012

The Internet has been in an uproar since the Cyber Intelligence Sharing and Protection Act (CISPA) was rushed through the U.S. House of Representatives on Thursday (CISPA primer here).

Summary of the situation: “Insanity: CISPA Just Got Way Worse, And Then Passed On Rushed Vote.” CISPA now heads to the Senate but President Obama has already threatened to veto the bill, citing its flaws,… read more

State-of-the-art virtual-reality system is key to medical discovery

For team of neurosurgeons and researchers, CAVE2 could revolutionize stroke prevention and treatment
December 13, 2012

Surgeons from the University of Illinois Hospital & Health Sciences Systems Neurosurgery Department view a simulation of the human brain vasculature and cortical tissue in the CAVE2 Hybrid Reality Environment. This project is a collaboration between the University of Illinois at Chicago's (UIC) Electronic Visualization Laboratory (EVL) and Bioengineering Department's Laboratory for Product and Process Design. EVL OmegaLib software is used to display the 3D model in the CAVE2 System. (Credit: Lance Long for Electronic Visualization Laboratory/University of Illinois at Chicago)

A team of neurosurgeons from the College of Medicine at the University of Illinois at Chicago (UIC) recently stepped into CAVE2 — a next-generation, large-scale, 320-degree, immersive, 3-D virtual environment — to solve a vexing problem that presented itself in the arteries of the brain of a real patient.

The method they used could someday benefit hundreds of thousands of Americans who fall… read more

Yung Chang and her colleagues at Arizona State University’s Biodesign Institute have launched an ambitious new project designed to attack nicotine dependence in a radically new way.

The research effort, pursued under a new $3.3 million grant from the National Institute of Drug Abuse, will attempt to design a vaccine conferring immunity to nicotine, using nanoscale structures assembled from DNA.… read more

The Titan Arm helps you lift 40 more pounds

But there no plans to sell it as a product yet.
October 30, 2013

titan_arm

Out of shape and can’t lift something? No prob,  just strap on an external bicep — the Titan Arm, a new invention from a group of engineering students at the University of Pennsylvania.

That’s if it’s ever available commercially (co-inventor Nick McGill told KurzweilAI they’re working on it, no date yet). If so, the Titan Arm will help lift 40 pounds more than you normally can.… read more

Google innovations at Google I/O

Google announced several innovations at  7th annual Google I/O developer conference (Google I/O) Wednesday. Among them:

Android Wear connects your phone to your wrist (say “Ok Google” to ask questions, read or send a text, get alerts, schedule a meeting, etc.). Google also announced that two Android wearables, the LG G Watch and Samsung Gear Live, are available to order today, and the Moto 360 from Motorola… read more

Rocket powered by nuclear fusion could send humans to Mars

April 8, 2013

University of Washington researchers and scientists are building components of a fusion-powered rocket aimed to clear many of the hurdles that block deep space travel, including long times in transit, exorbitant costs, and health risks.

“Using existing rocket fuels, it’s nearly impossible for humans to explore much beyond Earth,” said lead researcher John Slough, a UW research associate professor of aeronautics and astronautics.

“We are hoping… read more

World’s lightest material is 100 times lighter than Styrofoam

November 18, 2011

Ultra light metal

The world’s lightest material — with a density of 0.9 mg/cc — about 100 times lighter than Styrofoam — has been developed by a team of researchers from UC Irvine, HRL Laboratories, and the California Institute of Technology.

The new material, using nickel-phosphorous thin films, redefines the limits of lightweight materials because of its unique “micro-lattice” cellular architecture. The researchers were able to make a material that… read more

DNA data overload

Computing, not sequencing, is now the slower and more costly aspect of genomics research
July 17, 2013

(Credit: Filip Federowicz (filu))

A flood of genetic data is being produced much faster than current computers can turn it into useful information, Johns Hopkins bioinformatics experts warn.

The source: rapidly increasing speed and declining cost of DNA sequencer machines, which chop extremely long strands of biochemical components into more manageable small segments.

But these sequencers do not yield important biological information that researchers “can read like a… read more

Google’s new privacy policy: what has changed and what you can do about it

March 3, 2012

Google’s broad new privacy policy went into effect March 1.

“The main change is for users with Google Accounts,” Google said at the time of its January announcement. “Our new Privacy Policy makes clear that, if you’re signed in, we may combine information you’ve provided from one service with information from other services.” European regulators are claiming it violates data protection laws,

Bio patch can regrow bone for dental implants and craniofacial defects

November 11, 2013

Researchers at the University of Iowa have created a bio patch to regenerate missing or damaged bone. The patch has been shown to nearly fully regrow missing skull, seen in the image above. Image courtesy of Satheesh Elangovan.

Researchers at the University of Iowa have created a bio patch to regenerate missing or damaged bone by putting DNA into a nano-sized particle that delivers bone-producing instructions directly into cells via genes.

“This is the first study to use plasmid DNA encoding platelet derived growth factor (PDGF) for bone regeneration applications,” researcher Aliasger K. Salem, Ph.D. — a professor in the College of Pharmacy and a co-corresponding author on the… read more
