Our eyes may be our window to the world, but how do we make sense of the thousands of images that flood our retinas each day? Scientists at the University of California, Berkeley, have found that the brain is wired to put in order all the categories of objects and actions that we see. They have created the first interactive map of how the brain organizes these groupings.

Quantum computing, where bits of information, or "qubits," are represented by the state of single atomic particles or photons of light, won't be of much use unless we can read the results. Cornell researchers have taken a step in that direction with a device that can measure the presence of just a few photons without disturbing them.

Madison, Wisconsin - How could a few pictures of a dog in the grass illustrate key concepts underlying computer vision, a sophisticated science aimed at teaching machines to perform visual tasks for humans - such as recognizing faces, objects and patterns? Vikas Singh , assistant professor of biostatistics and medical informatics at the University of Wisconsin School of Medicine and Public Health, and graduate students Maxwell Collins and Jia Xu understand the relationship very well.

UK, German and US scientists decipher complex genetic code to create new tools for breeders and researchers across the world. Scientists, including Keith Edwards and Gary Barker from the University of Bristol, have unlocked key components of the genetic code of one of the world's most important crops.

A virtual character produces the same facial expressions as its user. It makes a video game, chat, or an animated film both fun and fast.

Scientists have developed a statistical image analysis method which can assist in the grading of breast cancer by automatically segmenting tumour regions and detecting dividing cells in tissue samples. The system, developed at the University of Warwick, promises to bring objectivity and automation to the cancer grading process which is used to determine the aggressiveness of the treatment offered to the patient.

Word choices on political issues reveal ways of thinking Communication and information science researches have developed a free online tool that offers a new way of looking at the news. "Reflext" provides a glimpse into how political events are being covered and discussed. The Reflext site analyzes content from 10 major media outlets, more than 30 political blogs and recent presidential campaign speeches, using the linguistic concept of "selectional preference," which identifies associations among words.

A new Government research project , undertaken by an international team of researchers including experts from the University of Bristol, into the advantages and risks of computer-based trading in financial markets has shown it to have beneficial effects but warned of the risks of greater instability.

A cell phone application enables Indian farmers to better negotiate the sale of their harvests. Farmbook is designed for use by this population segment, where illiteracy is very common.

A research team from the University of Bristol's Centre for Quantum Photonics (CQP) have brought the reality of a quantum computer one step closer by experimentally demonstrating a technique for significantly reducing the physical resources required for quantum factoring. The team have shown how it is possible to recycle the particles inside a quantum computer, so that quantum factoring can be achieved with only one third of the particles originally required.

Like cleaning the lenses of a foggy pair of glasses, scientists are now able to use a technique developed by UCLA researchers and their European colleagues to produce three-dimensional images of breast tissue that are two to three times sharper than those made using current CT scanners at hospitals.

New privacy threats have been discovered by University of Birmingham researchers which allow the physical presence of mobile phones operating on 3G networks to be tracked by third parties. This research will be presented at the ACM conference on Computer and Security in Raleigh, North Carolina on Tuesday 16th October 2012.

A new clinical study spearheaded by the dean of UCLA's School of Nursing has found a direct correlation between pressure ulcers — commonly known as bedsores — and patient mortality and increased hospitalization. The research is believed to be the first of its kind to use data directly from medical records to assess the impact of hospital-acquired pressure ulcers on Medicare patients at national and state levels.

Measuring progesterone levels in women with pain or bleeding during early pregnancy is a useful way to help to discriminate between a viable and a non-viable pregnancy, according to research by University of Birmingham researchers published on bmj.com today The results suggest that a low level of progesterone in these women can rule out a viable pregnancy in the vast majority of cases.

The test, code named "Divider," was detonated on Sept. 23, 1992 as the last of an eight-test series called "Julin." LOS ALAMOS, New Mexico, Sept. 26, 2012—Two decades ago the last full-scale underground test of a nuclear weapon was conducted by Los Alamos National Laboratory at the Nevada Test Site.
