It's a bubble, but not as we know it

Multi-sensory technology that creates soap bubbles, which can have images projected onto them or when the bubbles are burst release a scent, 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 on human-computer interfaces - ACM CHI 2014 [26 April-1 May], could be used in areas such as gaming or education and encourage a new way of thinking about multi-sensory technologies.

Atomic switcheroo explains origins of thin-film solar cell mystery

OAK RIDGE, Tenn., April 23, 2014 — Treating cadmium-telluride (CdTe) solar cell materials with cadmium-chloride improves their efficiency, but researchers have not fully understood why. Now, an atomic-scale examination of the thin-film solar cells led by the Department of Energy's Oak Ridge National Laboratory has answered this decades-long debate about the materials' photovoltaic efficiency increase after treatment.

Increased infrastructure required for effective oil spill response in US Arctic

WASHINGTON – A changing climate is increasing the accessibility of U.S. Arctic waters to commercial activities such as shipping, oil and gas development, and tourism, raising concern about the risk of oil spills. A new report from the National Research Council says that a full suite of proven oil response tools is needed to address potential oil spills in U.S. Arctic waters, but not all of them are readily available.

Change 'authoritarian' football culture to produce future stars, says research

Premier League soccer stars are subjecting their club's junior players to regular insults and practical jokes in a humiliating rite of passage, the British Sociological Association's annual conference in Leeds heard today. [Wednesday 23 April 2014]

This was part of an "authoritarian" treatment of youth team players which undermined attempts to change the culture of clubs and produce better footballers, Dr Chris Platts, of Sheffield Hallam University's Academy of Sport and Physical Activity, said.

Steering chemical reactions with laser pulses

Usually, chemical reactions just take their course, much like a ball rolling downhill. However, it is also possible to deliberately control chemical reactions: at the Vienna University of Technology, molecules are hit with femtosecond laser pulses, changing the distribution of electrons in the molecule. This interaction is so short that at first it does not have any discernable influence on the atomic nuclei, which have much more mass than the electrons.

Nanoreporters tell 'sour' oil from 'sweet'

Scientists at Rice University have created a nanoscale detector that checks for and reports on the presence of hydrogen sulfide in crude oil and natural gas while they're still in the ground.

The nanoreporter is based on nanometer-sized carbon material developed by a consortium of Rice labs led by chemist James Tour and is the subject of a new paper published this month in the American Chemical Society journal ACS Applied Materials and Interfaces.

Neuroimaging: Live from inside the cell

Reactive oxygen species are important intracellular signaling molecules, but their mode of action is complex: In low concentrations they regulate key aspects of cellular function and behavior, while at high concentrations they can cause "oxidative stress", which damages organelles, membranes and DNA.

AMP publishes curriculum recommendations for medical laboratory scientists

Bethesda, MD, April 22, 2014: The Association for Molecular Pathology (AMP) released a report today in The Journal of Molecular Diagnostics on recommendations for a molecular diagnostics curriculum at both the baccalaureate and master's levels of education. The report was prepared by the Medical Laboratory Scientist (MLS) Curriculum Task Force of the AMP Training and Education Committee.

Mantis shrimp stronger than airplanes

Inspired by the fist-like club of a mantis shrimp, a team of researchers led by University of California, Riverside, in collaboration with University of Southern California and Purdue University, have developed a design structure for composite materials that is more impact resistant and tougher than the standard used in airplanes.

Vacuum ultraviolet lamp of the future created in Japan

WASHINGTON D.C., April 22, 2014 -- A team of researchers in Japan has developed a solid-state lamp that emits high-energy ultraviolet (UV) light at the shortest wavelengths ever recorded for such a device, from 140 to 220 nanometers. This is within the range of vacuum-UV light -- so named because while light of that energy can propagate in a vacuum, it is quickly absorbed by oxygen in the air.

Ask yourself: Will you help the environment?

This news release is available in French.

Whether it's recycling, composting or buying environmentally friendly products, guilt can be a strong motivator — not just on Earth Day.

New design for mobile phone masts could cut carbon emissions

A breakthrough in the design of signal amplifiers for mobile phone masts could deliver a massive 200MW cut in the load on UK power stations, reducing CO2 emissions by around 0.5 million tonnes a year.

Funded by the Engineering and Physical Sciences Research Council (EPSRC), the Universities of Bristol and Cardiff have designed an amplifier that works at 50 per cent efficiency compared with the 30 per cent now typically achieved.

Like a hall of mirrors, nanostructures trap photons inside ultrathin solar cells

In the quest to make sun power more competitive, researchers are designing ultrathin solar cells that cut material costs. At the same time they're keeping these thin cells efficient by sculpting their surfaces with photovoltaic nanostructures that behave like a molecular hall of mirrors.

"We want to make sure light spends more quality time inside a solar cell," said Mark Brongersma, a professor of materials science and engineering at Stanford and co-author of a review article in Nature Materials.

Grasp of SQUIDs dynamics facilitates eavesdropping

Theoretical physicists are currently exploring the dynamics of a very unusual kind of device called a SQUID. This Superconducting Quantum Interference Device is a highly sensitive magnetometer used to measure extremely subtle magnetic fields. It is made of two thin regions of insulating material that separate two superconductors – referred to as Josephson junctions – placed in parallel into a ring of superconducting material.

Carnegie Mellon system lets iPad users explore data with their fingers

PITTSBURGH—Spreadsheets may have been the original killer app for personal computers, but data tables don't play to the strengths of multi-touch devices such as tablets. So researchers at Carnegie Mellon University have developed a visualization approach that allows people to explore complex data with their fingers.
