Bioteeth generated from your own cells

March 12, 2013

Researchers are developing a method to replace missing teeth with new bioengineered teeth generated from a person’s own gum cells.

Current implant-based methods of whole tooth replacement fail to reproduce a natural root structure and as a consequence of the friction from eating and other jaw movement, loss of jaw bone can occur around the implant.

Research towards producing bioengineered teeth (bioteeth) has largely focused on generating… read more

World’s smallest electronic diode made from single DNA molecule

Electronic components 1,000 times smaller than with silicon may be possible
April 6, 2016

DNA diode ft

Nanoscale electronic components can be made from single DNA molecules, as researchers at the University of Georgia and at Ben-Gurion University in Israel have demonstrated, using a single molecule of DNA to create the world’s smallest diode.

A diode is a component vital to electronic devices that allows current to flow in one direction but prevents its flow in the other direction.… read more

The real Limitless drug

April 8, 2013

Modafinil (Provigil in the United States) was first approved by the FDA in 1998 for the treatment of narcolepsy, but since has become better known as a nootropic, a “smart drug,” especially among entrepreneurs, says New York magazine.

Rumored to be the model for the fictional pills in the movie Limitless, no scientist has conducted a study of its long-term effects on healthy brains yet. At the very… read more

Michigan Technological University, scientists have replaced expensive ($1,500 an ounce) platinum in solar cells with low-cost 3D graphene.

Regular graphene is a two-dimensional form of carbon. Yun Hang Hu, the Charles and Caroll McArthur Professor of Materials Science and Engineering at MTU, and his team invented a way to synthesize a 3D version, with a honeycomb-like structure.

The 3D graphene had excellent conductivity and high… read more

Jetpack to be available in 2014

September 23, 2013

New Zealand’s Martin Aircraft is developing the “first practical jetpack” and has done manned and unmanned flight tests of its latest prototype, Aviation Week reports.

When completed it will be aimed at first responders (such as fire services), planned to be available in 2014.

You will have to wait a bit longer for a personal JetPack.

Flight control is fly-by-wire (computer-controlled) and there’s… read more

Navy’s Star Wars-style laser weapon to be tested in Persian Gulf this summer

A "revolutionary capability" -- Chief of Naval Research
April 10, 2014

The U.S. Navy plans to install a prototype of the first laser weapon on USS Ponce for at-sea testing in the Persian Gulf late this summer.

The Laser Weapon System (LaWS) is a “revolutionary capability,” said Chief of Naval Research Rear Adm. Matthew Klunder. “It’s absolutely critical that we get this out to sea with our Sailors for these trials, because this very affordable technology is going to change… read more

Studying ethical questions as the brain’s black box Is unlocked

Excerpt from The New York Times
December 18, 2012

MRI Head

S. Matthew Liao, director of the bioethics program at New York University, has a singular title: neuroethicist.

Some researchers claim to be near to using fMRIs to read thoughts. Is this really happening?

The technology, though still crude, appears to be getting closer. For instance, there’s one research group that asks subjects to watch movies. When they

Companies discover untapped brain power: autistics

July 21, 2013

Companies are discovering the untapped brain power of a group long thought ill suited to the office: adults on the autistic spectrum. Joshua Kendall, author of America’s Obsessives, reports at The Daily Beast on one Danish man’s mission to employ the seemingly unemployable — and successful famous “obsessives”* (think Jefferson and Heinz) in American history.

While the 1% of the population with ASDs may have considerable difficulty navigating… read more

AR goggles restore depth perception to people blind in one eye

People who’ve lost sight in one eye can still see with the other, but they lack binocular depth perception.

A pair of augmented reality glasses being built at the University of Yamanashi in Japan artificially introduces a feeling of depth in a person’s healthy eye, MIT Technology Review reports.

The researchers created software that makes use of the twin cameras in a Vuzix Wrap… read more

GOP lawmaker seeks ‘virtual Congress’ with telecommuting plan

Under a resolution Pearce introduced on Thursday, Rep. Steve Pearce (R-N.M.) wants to create a “virtual Congress,” where lawmakers would leverage videoconferencing and other remote work technology to to hold hearings, debate and vote on legislation virtually from their home district offices, The Hill reports.

Pearce says the resolution would eradicate the need for members to jet back and forth from their districts to Washington each weekend. This… read more

Rats use GPS to root out land mines

June 8, 2012

Two Bucknell University professors are working with a U.S. Department of Defense contractor to develop faster and more sophisticated technology and methods to detect land mines. The team has devised a system to train rats to recognize and respond to the explosives.

The rats will be outfitted with miniature backpacks and wireless transmitters that track their positions and movements. During the first part of their training, the… read more

Resveratrol found to activate ancient stress response and at 1,000 times lower doses

December 30, 2014

Scientists at The Scripps Research Institute (TSRI) have found that a fundamental new mechanism for the known beneficial effects of resveratrol — the grapes and red-wine ingredient once touted as an elixir of youth: it powerfully activates an evolutionarily ancient stress response in human cells.

“This stress response represents a layer of biology that has been largely overlooked, and resveratrol turns out to activate it at much lower concentrations… read more

Automated drug design using synthetic DNA self-assembly

Using a simple “drag-and-drop” computer interface and DNA self-assembly techniques, Parabon NanoLabs researchers have developed a new automated method of drug development that could reduce the time required to create and test medications, with the support of an NSF Technology Enhancement for Commercial Partnerships grant.

“We can now ‘print,’ molecule by molecule, exactly the compound that we want,” says Steven Armentrout, the principal investigator… read more

Biological transistor enables computing within living cells

Stanford University bioengineers have taken computing beyond mechanics and electronics into the living realm of biology by creating the “transcriptor” — a biological transistor made from DNA and RNA.

In electronics, a transistor controls the flow of electrons along a circuit. Similarly, a transcriptor controls the flow of a specific protein, RNA polymerase, as it travels along a strand of DNA.

“Transcriptors are the… read more
