Telltale DNA sucked out of household dust (article preview)

June 2, 2008

In a finding reminiscent of the movie Gattaca, Virginia Commonwealth University researchers have identified human DNA in dust.

Though each sample contained just trillionths of a gram of DNA, it was enough for amplification and profiling via the DNA kits used in forensic labs.

The amount of DNA in dust is tiny and from so many people that singling out any individual is currently difficult.

Telomere shortening may be early marker of cancer activity

July 16, 2003

Telomere shortening may be one of the earliest and most prevalent changes on a cell’s path to cancer, according to two studies presented at the 94th Annual Meeting of the American Association for Cancer Research (AACR).

As cells divide and age, telomere DNA is lost and telomeres get shorter and shorter. The new study suggests that telomere dysfunction from the shortening may play a causal role in human intraepithelial… read more

Telstra chief hosts conference as hologram

May 28, 2008

In an Australian first, Telstra’s high definition “holographic” video projection system projected a life-sized, real-time hologram of an executive, who interacted with business executives at an Adelaide conference while he stood in front of cameras in Telstra’s Melbourne office.

Temperature-sensitive gel scaffold regenerates craniofacial bone

December 13, 2013


Rice University bioengineers have developed a hydrogel scaffold for regeneratomg craniofacial bone tissue. The hydrogel starts as a liquid, solidifies into a gel in the body, and liquefies again for removal.

The material developed in the Rice lab of bioengineer Antonios Mikos is a soluble liquid at room temperature that can be injected where needed. At body temperature, the material turns instantly into a gel to… read more

‘Temporal cloaking’ could bring more secure optical communications

June 7, 2013

Output for a particular sequence of ones and zeros.<br />
Although the binary data specified on the bottom of the plot are clearly detected<br />
when the cloak is off, the voltage swings indicative of bit transmission are<br />
suppressed to a nearly flat line when the cloak is on.


Purdue University researchers have demonstrated a method for “temporal cloaking” of optical communications, representing a potential tool to thwart would-be eavesdroppers and improve security for telecommunications.

“More work has to be done before this approach finds practical application, but it does use technology that could integrate smoothly into the existing telecommunications infrastructure,” said Purdue graduate student Joseph Lukens, working with … read more

Temporary tattoos could make ‘electronic telepathy,’ ‘telekinesis’ possible

Temporary electronic tattoos could soon help people fly drones with only thought and talk seemingly telepathically without speech over smartphones

The devices are less than 100 microns thick, the average diameter of a human hair. They consist of circuitry embedded in a layer or rubbery polyester that allow them to stretch, bend and wrinkle. They are barely visible when placed on skin, making them easy to conceal from others.

The devices can detect electrical signals linked with brain waves, and incorporate solar cells for power and antennas that allow… read more

‘Ten Commandments’ of race and genetics issued

July 18, 2008

A multidisciplinary group focused on contentious issues related to race, genetic markers and medicine has released a set of 10 guiding principles for the scientific community.

The group–ranging from geneticists and psychologists to historians and philosophers–was led by anthropologist Sandra Soo-Jin Lee of Stanford University.

The guidelines include “members of the same race may have different underlying genetics,” and “oversimplified science feeds popular misconceptions.”

Ten extinct beasts that could walk the Earth again

January 8, 2009

The genomes of several extinct species besides the mammoth are already being sequenced, but turning these into living creatures will not be easy.

It’s only going to be possible with creatures for which we can retrieve a complete genome sequence. “It’s really only worth studying specimens that are less than 100,000 years old,” says Pennsylvania State University molecular biologist Stephan Schuster.

Ten extraordinary Pentagon mind experiments

March 15, 2013


Duke University experiments in connecting the brains of two rats through implanted electrodes and the planned Brain Activity Map project reflect a growing Pentagon interest in neuroscience for applications that range from such far-off ideas as teleoperation of military devices (think mind-controlled drones), to more near-term and less controversial technology, like prosthetics controlled by the human brain, BBC Future more

Ten physical gestures that have been patented

"Gesture profiles" patent for operating the Kinect (credit: Microsoft)

It sounds crazy, but tech companies have been patenting physical gestures for almost two decades now.

In a world ruled by touchscreens, Kinect, and Guitar Hero, these businesses don’t want people making certain gestures without paying for it.

Here are 10 physical gestures that have been patented:

  1. Slide to unlock (Apple)
  2. Multi-touch gestures for touchscreen or trackpad (Apple)
  3. Drawing each letter of the alphabet

New Scientist has assessed the prospects of 10 of the coolest gadgets that in 30 years’ time may change our lives.

Ten technologies to watch in 2003

January 3, 2003

Terabyte holographic storage, ubiquitous radio-frequency identity chips, affordable consumer robots, and larger/cheaper LCD displays are among the new technologies to watch this year.

Ten times more energy-efficient microchip recharges itself

March 18, 2008

Researchers at MIT and Texas Instruments have designed a new lower-voltage chip that they claim could be up to 10 times more energy-efficient than the current generation.

The power consumption in the new chip is so low that devices using them may even be able to be recharged by human body heat from implantable medical devices such as pacemakers and health monitors, and it could lead to cell phones,… read more

Ten times more throughput on optic fibers

December 9, 2013


EPFL scientists have shown how to achieve a dramatic increase in the capacity of optical fibers by reducing the amount of space required between the pulses of light that transport data.

Optical fibers carry data in the form of pulses of light over distances of thousands of miles at high speeds. But their capacity is limited, because the pulses of light need to be lined up one… read more

Ten ways 3D printing could change space

April 16, 2014

A close up of a ligthweight titanium lattice ball manufactured using the Additive Manufacturing or 3D printing process. This design is a good example of AM capabilities: these hollow balls possesing a complex external geometry could not have been manufactured in a single part using a conventional manufacturing process. But they are incredibly light while also stiff, opening up possibilities for future space applications.

The European Space Agency (ESA) is investigating the potential of additive manufacturing (AM), or 3D printing, to transform how space missions are put together, and has identified ten ways.

1. Items impossible to make any other way

This titanium-lattice ball is a good example of additive manufacturing capabilities. These hollow balls have a complex external geometry,  making them incredibly light while remaining stiff and… read more
