Scientists discover interstellar stardust

August 18, 2014 9:41 am | by EurekAlert! | Comments

We may joke about looking for a needle in a haystack, but that's nothing compared to searching for stardust in a foil! A new paper published in Science reveals that such work has led to the discovery of seven dust particles that are not only out of this world, they're out of this solar system....

'Cavity protection effect' helps to conserve quantum information

August 18, 2014 9:38 am | by EurekAlert! | Comments

The electronics we use for our computers only knows two different states: zero or one. Quantum systems on the other hand can be in different states at once, they can store a superposition of "zero" and "one". This phenomenon could be used to build ultrafast quantum computers....

Fascinating rhythm: Light pulses illuminate a rare black hole

August 18, 2014 9:33 am | by EurekAlert! | Comments

The universe has so many black holes that it's impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big, and colossal. Astronomers know that black holes ranging from about 10 times to 100 times....

Microchip reveals how tumor cells transition to invasion

August 18, 2014 9:28 am | by EurekAlert! | Comments

Using a microengineered device that acts as an obstacle course for cells, researchers have shed new light on a cellular metamorphosis thought to play a role in tumor cell invasion throughout the body. The epithelial-mesenchymal transition (EMT) is a process in which epithelial cells ...

A shift in the code: New method reveals hidden genetic landscape

August 18, 2014 9:24 am | by EurekAlert! | Comments

With three billion letters in the human genome, it seems hard to believe that adding a DNA base here or removing a DNA base there could have much of an effect on our health. In fact, such insertions and deletions can dramatically alter biological function, leading to diseases from autism to cancer....

Artificial cells act like the real thing

August 18, 2014 9:20 am | by EurekAlert! | Comments

Imitation, they say, is the sincerest form of flattery, but mimicking the intricate networks and dynamic interactions that are inherent to living cells is difficult to achieve outside the cell. Now, as published in Science, Weizmann Institute scientists have created an artificial, network-like cell system....

Hitchhiking robot charms its way across Canada

August 18, 2014 9:16 am | by CHARMAINE NORONHA, Associated Press | Comments

He has dipped his boots in Lake Superior, crashed a wedding and attended an Aboriginal powwow. A talking, bucket-bodied robot has enthralled Canadians since it departed from Halifax last month on a hitchhiking journey to the Pacific coast. HitchBOT, created by team of Ontario-based communication researchers ...

Wireless sensors and flying robots: A way to monitor deteriorating bridges

August 15, 2014 12:42 pm | by EurekAlert! | Comments

As a report from the Obama administration warns that one in four bridges in the United States needs significant repair or cannot handle automobile traffic, Tufts University engineers are employing wireless sensors and flying robots that could have the potential to help authorities....

8 million Chromebooks to ship in 2014, 5% of global notebook PC market

August 15, 2014 12:19 pm | by DisplaySearch | Comments

According to the Quarterly Mobile PC Shipment and Forecast Report, notebook PC shipments will reach 167M in 2014, an 8% Y/Y decline. The reasons for the decline are mainly the maturity of the notebook PC market, slowdown in Windows 8 replacement, and in the consumer market, low-priced tablet PCs ...

Photos of the Day: A self-organizing thousand-robot swarm

August 15, 2014 12:03 pm | by Harvard University | Comments

Just as trillions of individual cells can assemble into an intelligent organism, or a thousand starlings can form a great flowing murmuration across the sky, the Kilobots demonstrate how complexity can arise from very simple behaviors performed en masse....

Molecular engineers record an electron's quantum behavior

August 15, 2014 11:42 am | by EurekAlert! | Comments

A team of researchers led by the University of Chicago has developed a technique to record the quantum mechanical behavior of an individual electron contained within a nanoscale defect in diamond. Their technique uses ultrafast pulses of laser light both to control the defect's entire quantum state....

New Milky Way maps help solve stubborn interstellar material mystery

August 15, 2014 11:38 am | by EurekAlert! | Comments

An international team of sky scholars, including a key researcher from Johns Hopkins, has produced new maps of the material located between the stars in the Milky Way. The results should move astronomers closer to cracking a stardust puzzle that has vexed them for nearly a century....
