Scientists gain new insight into mysterious electronic phenomenon

April 11, 2014 1:10 pm | by Argonne National Laboratory | Comments

Thanks to a new Argonne study, researchers have identified and solved at least one paradox in the behavior of high-temperature superconductors. The riddle involves a phenomenon called the “pseudogap,” a region of energy levels in which relatively few electrons are allowed to exist.

Researchers bolster development of programmable quantum computers

April 11, 2014 12:55 pm | by EurekAlert! | Comments

University of Chicago researchers and their colleagues at University College London have performed a proof-of-concept experiment that will aid the future development of programmable quantum computers. Many complex problems are difficult and slow to solve using conventional computers....

Thermoelectric generator on glass fabric for wearable electronic devices

April 11, 2014 12:37 pm | by EurekAlert! | Comments

Wearable computers or devices have been hailed as the next generation of mobile electronic gadgets, from smart watches to smart glasses to smart pacemakers. For electronics to be worn by a user, they must be light, flexible, and equipped with a power source, which could be a portable, long-lasting battery....

Finding the target: How timing is critical in establishing an olfactory wiring map

April 11, 2014 12:35 pm | by EurekAlert! | Comments

The human nose expresses nearly 400 odorant receptors, which allow us to distinguish a large number of scents. In mice the number of odor receptors is closer to 1000. Each olfactory neuron displays only a single type of receptor and all neurons with the same receptors are connected to the same spot....

Antennae help flies 'cruise' in gusty winds

April 11, 2014 12:32 pm | by EurekAlert! | Comments

Due to its well-studied genome and small size, the humble fruit fly has been used as a model to study hundreds of human health issues ranging from Alzheimer's to obesity. However, Michael Dickinson, Esther M. and Abe M. Zarem Professor of Bioengineering at Caltech, is more interested in the flies themselves....

Appearance of night-shining clouds has increased

April 11, 2014 12:31 pm | by EurekAlert! | Comments

First spotted in 1885, silvery blue clouds sometimes hover in the night sky near the poles, appearing to give off their own glowing light. Known as noctilucent clouds, this phenomenon began to be sighted at lower and lower latitudes -- between the 40th and 50th parallel....

SU professors test boundaries of 'new physics' with discovery of 4-quark hadron

April 11, 2014 11:33 am | by EurekAlert! | Comments

Physicists in Syracuse University's College of Arts and Sciences have helped confirm the existence of exotic hadrons—a type of matter that cannot be classified within the traditional quark model. Their finding is the subject of a forthcoming article....

Sneak a peek through the mist to technology of the future

April 11, 2014 11:30 am | by EurekAlert! | Comments

A tabletop display with personal screens made from a curtain of mist that allow users to move images around and push through the fog-screens and onto the display, will be unveiled at an international conference later this month. The research paper, to be presented at one of the world's most important conferences...

3-D printing cancer cells to mimic tumors

April 11, 2014 11:28 am | by EurekAlert! | Comments

A group of researchers in China and the US have successfully created a 3D model of a cancerous tumour using a 3D printer. The model, which consists of a scaffold of fibrous proteins coated in cervical cancer cells, has provided a realistic 3D representation of a tumour's environment....

Scientists grow cartilage to reconstruct nose

April 11, 2014 11:27 am | by EurekAlert! | Comments

Scientists at the University of Basel report first ever successful nose reconstruction surgery using cartilage grown in the laboratory. Cartilage cells were extracted from the patient's nasal septum, multiplied and expanded onto a collagen membrane....

Eye of the beholder -- improving the human-robot connection

April 11, 2014 11:24 am | by EurekAlert! | Comments

Researchers are programming robots to communicate with people using human-like body language and cues, an important step toward bringing robots into homes. Researchers at the University of British Columbia enlisted the help of a human-friendly robot named Charlie....

Researchers develop ErSb nanostructures with applications in infrared and terahertz ranges

April 11, 2014 11:23 am | by EurekAlert! | Comments

In a feat that may provide a promising array of applications, from energy efficiency to telecommunications to enhanced imaging, researchers at UC Santa Barbara have created a compound semiconductor of nearly perfect quality with embedded nanostructures containing ordered lines of atoms....

The ATM strikes back

April 11, 2014 11:19 am | by EurekAlert! | Comments

Its head and pronotum are usually rusty red, and its abdomen blue or shiny green: the bombardier beetle is approximately one centimetre long and common to Central Europe. At first glance, it appears harmless, but it possesses what is surely the most aggressive chemical defence system in nature....
