Geography of global electronic waste ('e-waste') burden

Wed, 07/23/2014 - 15:11
As local and national governments struggle to deal with ever-growing piles of electronic waste, scientists are now refining the picture of just how much there is and where it really ends up. Their study found that nearly a quarter of e-waste that developed countries discard floods into just seven developing countries -- with major potential health risks for the people who live there.

3-D images of cardiac dynamics in zebrafish captured

Wed, 07/23/2014 - 15:10
Researchers report how they managed to capture detailed three-dimensional images of cardiac dynamics in zebrafish. The novel approach: They combine high-speed Selective Plane Illumination Microscopy (SPIM) and clever image processing to reconstruct multi-view movie stacks of the beating heart.

Can machines think? Misidentification of humans as machines in Turing tests

Wed, 07/23/2014 - 15:08
Pairs were set up and judges were tasked with identifying whether who they were talking to was human or a computer. Can machines be successful in 'being human' in real conversations?

Virtual humans as models: Say goodbye to Naomi, Kate and Claudia ... Enter 'Ava'

Wed, 07/23/2014 - 15:07
Forget top models. With haute couture turning to virtual reality, holographic versions of the world’s most in-demand models are now striding down the catwalks alongside their human counterparts. But does this mean temperamental models are on their way out?  New research has been revealed which shows it could be the end of the fashion world as we know it.

Linking television and the Internet

Wed, 07/23/2014 - 15:07
In the “LinkedTV“ project, researchers are seamlessly connecting TV offerings with the Internet. Audiences will benefit from an informative and personalized viewing experience.

Electronic nose could aid in rescue missions

Wed, 07/23/2014 - 15:04
Researchers have developed a device that allows multiple robotic platforms to follow the path of certain odors. A technology which could aid the search and rescue of people in case of natural disasters such as earthquakes, hurricanes or floods.

Dopamine transporter: Stampede supercomputer used to study common link between addiction, neurological disease

Tue, 07/22/2014 - 20:43
The XSEDE-allocated Stampede supercomputer has been used to study the dopamine transporter. Stampede is ranked seventh on the Top 500 list of supercomputers. Its research links altered dopamine signaling and dopamine transporter function to neurological and psychiatric diseases including early-onset Parkinsonism, ADHD, and cocaine addiction.

Quantum leap in lasers brightens future for quantum computing

Tue, 07/22/2014 - 17:07
Scientists have devised a breakthrough laser that uses a single artificial atom to generate and emit particles of light. The laser may play a crucial role in the development of quantum computers, which are predicted to eventually outperform today's most powerful supercomputers.

'Comb on a chip' powers new atomic clock design

Tue, 07/22/2014 - 15:19
Researchers have demonstrated a novel design for a small atomic clock that is based on a chip-scale frequency comb, or a microcomb.

A new multi-bit 'spin' for magnetic random access memory storage

Tue, 07/22/2014 - 15:14
Interest in magnetic random access memory (MRAM) is escalating, thanks to demand for fast, low-cost, nonvolatile, low-consumption, secure memory devices. MRAM boasts all of these advantages as an emerging technology, but so far it hasn't been able to match flash memory in terms of storage density. A research team reports an intriguing new multi-bit MRAM storage paradigm with the potential to rival flash memory.

High-precision software developed for diagnosing eye sensitivity

Tue, 07/22/2014 - 13:14
High-precision software for diagnosing eye sensitivity has been developed by researchers. This is a new technology that allows to quantify the degree of opacity in the posterior capsule of the eye caused by the growth of cells in the intraocular lens.

Computer privacy: Share button may share your browsing history, too

Chemists eye improved thin films with metal substitution

Mon, 07/21/2014 - 17:20
The yield so far is small, but chemists have developed a low-energy, solution-based mineral substitution process to make a precursor to transparent thin films that could find use in electronics and alternative energy devices.

Philosopher uses game theory to understand how words, actions acquire meaning

Mon, 07/21/2014 - 16:37
Why does the word "dog" have meaning? If you say "dog" to a friend, why does your friend understand you? A philosopher aims to address these types of questions in his latest research, which focuses on long-standing philosophical questions about semantic meaning. Philosophers and a mathematician are collaborating to use game theory to analyze communication and how it acquires meaning.

Size and age of plants impact their productivity more than climate

Mon, 07/21/2014 - 00:43
The size and age of plants has more of an impact on their productivity than temperature and precipitation, according to a landmark study. They show that variation in terrestrial ecosystems is characterized by a common mathematical relationship but that climate plays a relatively minor direct role. The results have important implications for models used to predict climate change effects on ecosystem function and worldwide food production.
