Australia is known for its overly large bugs, like the up-to-20-inch Titan stick insect. But the country also has tiny insects, like the itsy-bitsy wheat wheevil. Researchers with Australia's national science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), are trying out a method of super-sizing insects through 3D printing.

Small, sometimes nearly microscopic, insects from the Australian National Insect Collection are run through a 3D-scanning system and then printed out at magnified sizes in titanium. Why would you want to do this other than to leave one on someone's seat as a prank? The bigger versions give scientists a better look at the insect's anatomy in order to learn more about their surface characteristics or determine gender. Plus, it's just plain cool.… Read more

Foiling facial recognition systems that identify people based on photographs may be as simple as wearing a special set of glasses equipped with near-infrared LEDs powered by a battery pack. The LEDs are arranged around the nose and eyes. The human eye can't pick up the near-infrared, but a camera sees it as bright light, enough to obscure the face and confuse facial recognition software.

Researchers with the National Institute of Informatics and Kogakuin University in Japan developed the special privacy visor to counteract photographs and facial recognition software that could invade privacy. Details on the glasses were released late last year, but a prototype got a public showing at a recent open house.… Read more

It's long been observed that many kids with autism have a hard time communicating and socializing with others. Now a new study using MRI scans provides some clues as to why.

Thanks to a weaker connection between the brain's language and reward centers, the human voice may provide little to no pleasure at all to kids with autism.

As they report this week in the Proceedings of the National Academy of Sciences, researchers were able to spot "underconnectivity" using functional MRI, which tracks blood flow to look for brain activity.

Researchers scanned the brains of 20 … Read more

Sometimes a concept is simple but the tech behind it is not. This is the case with a new approach to identifying new viruses, which could ultimately lead to screening patients for viruses that haven't even been identified. (Think of the one currently rearing its deadly head in the Middle East.)

Researchers at Saint Louis University are using the next-gen sequencing approach transcriptome subtraction, and it really does employ basic arithmetic -- with very fancy tools. They take a human blood sample. Then they subtract the entire human genetic sequence from the genetic material in the sample. Then they … Read more

New York lawmakers are the latest to crackdown on 3D-printed guns.

Both a member of the New York city council and a state assemblywoman have introduced two different pieces of legislation that would either regulate or ban the manufacture of 3D-printed guns, according to New York Daily News.

The bill for New York City was introduced by Council Member Lewis Fidler on Wednesday. This bill aims to make it illegal for people to produce any part of a firearm using a 3D printer unless they are licensed gunsmiths. Also, each weapon must be registered with the police within a 72-hour … Read more

How does our top layer of skin -- the thin stratum corneum -- manage to keep water inside our bodies and microbes out, all while maintaining strength and elasticity, at just a fraction of the thickness of a sheet of paper?

In the first tests of its kind, scientists at the University of Bath are using a tiny "microneedle" with atomic force microscopy to probe the surface of the top layer of human skin and solve some of these mysteries.

Until now, researchers were able to use this form of microscopy only to analyze the surface of corneocytes, the cells that form the outer layer of the epidermis. Now, by adding a nanoneedle to the end of the probe, they can delve below the surface and shine a light on the cell structure within.… Read more

Ladies and gentlemen, may I now present your deep thought of the day: People who play video games are better at playing video games than people who don't play video games.

OK, new findings out of Duke may be a bit more complex than that, but there's not much of a spoiler alert to this one. Hours spent at a gaming console seem to translate directly to a test, taken at a computer, of how the brain tracks visual stimuli, according to a new study at the Duke School of Medicine.… Read more

The Large Hadron Collider is a monumentally awesome machine, and has given us tentative confirmation of the existence of the Higgs boson, the so-called "God particle." Now scientists hope to follow that with a new accelerator that could explain what makes up 95 percent of the universe.

At three ceremonies around the world Wednesday, researchers hailed blueprints for the International Linear Collider (ILC), a 19-mile-long smasher that might help solve the riddle of dark matter and dark energy, unseen forces with major gravitational effects. … Read more

When scientists at the University of Washington recently drilled into the skulls of seven people with severe epilepsy and placed thin sheets of electrodes directly onto their brains, they were surprised by the brain activity they observed.

While physicians were studying neuro activity to investigate seizure signals, a separate team of bioengineers was simultaneously on the lookout for exactly how the brains of the seven volunteers behaved as they learned to move a cursor using their thoughts alone. It turns out that, in as few as 10 minutes, activity went from being centered on the prefrontal cortex, which is associated with learning new skills, to areas seen during more automatic functions, such as waving one's hand or kicking a ball.

In other words, in just a matter of minutes these brains behaved as if they had already mastered these Jedi mind tricks.… Read more
