Quantum environmentalism: Putting a qubit's surroundings to good use

Posted: 02 Oct 2014 11:19 AM PDT

A qubit's environment, usually viewed as a threat to coherence, here serves as an aid to manipulating and interrogating the qubit.

Exotic matter: A closer look at the perfect fluid sheds light on what happened microseconds after the Big Bang

Posted: 02 Oct 2014 11:18 AM PDT

By combining data from two high-energy accelerators, nuclear scientists have refined the measurement of a remarkable property of exotic matter known as quark-gluon plasma. The findings reveal new aspects of the ultra-hot, 'perfect fluid' that give clues to the state of the young universe just microseconds after the big bang.

Boosting biofuel: Yeast made to tolerate high levels of ethanol, making them more productive

Posted: 02 Oct 2014 11:18 AM PDT

Yeast are commonly used to transform corn and other plant materials into biofuels such as ethanol. However, large concentrations of ethanol can be toxic to yeast, which has limited the production capacity of many yeast strains used in industry.

Elusive particle that is its own antiparticle observed

Posted: 02 Oct 2014 11:17 AM PDT

Scientists have observed an exotic particle that behaves simultaneously like matter and antimatter, a feat of math and engineering that could yield powerful computers based on quantum mechanics.

Ebola genome browser now online to aid researchers' response to crisis

Posted: 02 Oct 2014 09:53 AM PDT

The UC Santa Cruz Genomics Institute has just released a new Ebola genome browser to assist global efforts to develop a vaccine and antiserum to help stop the spread of the Ebola virus.

Teen Texting: Difference in girls, boys text talk, reflection on gender identity

Posted: 02 Oct 2014 09:34 AM PDT

Teenage years are a turbulent time of learning independence, developing social skills and experiencing sexuality and romance. Teens face peer groups pressure and have no micro guidance from parents. Texting is an important social communication channel for teens, giving the opportunity for anxiety free communication with the opposite sex. This study explores teenager's use of text, language differences between sexes and overall gender identity.

New approach to on-chip quantum computing

Posted: 02 Oct 2014 07:11 AM PDT

An international team of researchers is introducing a new method to achieve a different type of photon pair source that fits into the tiny space of a computer chip.

Doing math with your body

Posted: 02 Oct 2014 07:09 AM PDT

You do math in your head most of the time, but you can also teach your body how to do it. Researchers investigated how our brain processes and understands numbers and number size. They show that movements and sensory perception help us understand numbers.

Nanoparticles give up forensic secrets

Posted: 02 Oct 2014 05:43 AM PDT

A group of researchers from Switzerland has thrown light on the precise mechanisms responsible for the impressive ability of nanoparticles to detect fingermarks left at crime scenes.

Energy drinks cause insomnia, nervousness in athletes

Posted: 02 Oct 2014 05:43 AM PDT

A study analyzing the positive and negative effects of energy drinks on athletes has seen that, although in principle their sports performance was seen to improve by between 3% and 7%, there was also an increase in the frequency of insomnia, nervousness and the level of stimulation in the hours following competition, scientists report.

Internet addicts often suffer from additional disorders

Posted: 02 Oct 2014 05:41 AM PDT

Internet addicts often suffer from concomitant disorders, most frequently from depressive disorders, anxiety disorders and ADHS, researchers report.

Stressed out: Research sheds new light on why rechargeable batteries fail

Posted: 01 Oct 2014 10:31 AM PDT

Lithium ions traveling through a zinc antimonide anode cause local stress and phase transitions, a process dubbed atomic shuffling. These changes may help explain why most anodes made of layered materials eventually fail.

Wintertime ozone pollution in Utah oil and gas fields explained

Posted: 01 Oct 2014 10:30 AM PDT

Chemicals released into the air by oil and gas exploration, extraction and related activities can spark reactions that lead to high levels of ozone in wintertime, high enough to exceed federal health standards, according to new research.

'Stealth' nanoparticles could improve cancer vaccines

Posted: 01 Oct 2014 07:27 AM PDT

Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven't worked that well. Now, scientists have developed a new way to deliver vaccines that successfully stifled tumor growth when tested in laboratory mice. And the key is in the vaccine's unique stealthy nanoparticles.

Deconstruction of avant-garde cuisine could lead to even more fanciful dishes

Posted: 01 Oct 2014 07:26 AM PDT

One of the most iconic forms of avant-garde cuisine, also known as molecular gastronomy, involves the presentation of flavorful, edible liquids -- like cocktails or olive oil -- packaged into spheres. Now a team of scientists is getting to the bottom of what makes these delectable morsels possible.

Nanoparticles accumulate quickly in wetlands: Aquatic food chains might be harmed by molecules 'piggybacking' on carbon nanoparticles

Posted: 01 Oct 2014 07:26 AM PDT

Using mesocosms that closely approximate wetland ecosystems, researchers show carbon nanotubes accumulate quickly in sediments -- a tendency that could indirectly damage aquatic food chains by piggybacking harmful molecules.

All directions are not created equal for nanoscale heat sources

Posted: 01 Oct 2014 06:02 AM PDT

Thermal considerations are rapidly becoming one of the most serious design constraints in microelectronics, especially on submicron scale lengths. A new study has shown that standard thermal models will lead to the wrong answer in a three-dimensional heat-transfer problem if the dimensions of the heating element are on the order of one micron or smaller.

Sensor network tracks down illegal bomb-making

Posted: 01 Oct 2014 06:01 AM PDT

Terrorists can manufacture bombs with relative ease, few aids and easily accessible materials such as synthetic fertilizer. Not always do security forces succeed in preventing the attacks and tracking down illegal workshops in time. But bomb manufacturing leaves its traces: Remains of the synthetic fertilizer stick to stairs and doorknobs, waste from the manufacturing process gets into the sewerage and is deposited in air ducts.

First comprehensive meshfree numerical simulation of skeletal muscle tissue achieved

Posted: 30 Sep 2014 02:15 PM PDT

Engineers have completed the first comprehensive numerical simulation of skeletal muscle tissue using a method that uses the pixels in an image as data points for the computer simulation -- a method known as mesh-free simulation.
