New statistical method offers automatic mitotic cell detection for cancer diagnosis
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
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.

Quantum computing with recycled particles
Quantum computing with recycled particles
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.  The research is published in the latest issue of Nature Photonics .

Breakthrough technique images breast tumors in 3-D with great clarity, reduced radiation
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.

Vulnerabilities that allow mobile phone users to be tracked by friends and enemies
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.

Direct correlation between hospital bedsores, patient mortality
Direct correlation between hospital bedsores, patient mortality
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.

Progesterone test can predict viability of pregnancy
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.

Los Alamos National Laboratory marks 20 years without full-scale nuclear testing
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.

University researchers uncover the full scale and weaknesses of the monitoring of illegal file sharers
Research by computer scientists at the University of Birmingham has found that the monitoring of online file sharing is more prevalent than previously thought. They also conclude that in many cases, the evidence gathered through monitoring is not admissible in court. This research will be presented tomorrow (Tuesday 4 th September 2012) at the SecureComm Conference in Padua.

Supernovae of the Same Brightness, Cut From Vastly Different Cosmic Cloth
Supernovae of the Same Brightness, Cut From Vastly Different Cosmic Cloth
Berkeley, Calif., Aug 23, 2012 -Exploding stars called Type 1a supernova are ideal for measuring cosmic distance because they are bright enough to spot across the Universe and have relatively the same luminosity everywhere. Although astronomers have many theories about the kinds of star systems involved in these explosions (or progenitor systems), no one has ever directly observed one-until now.

Scientists shed light on glowing materials
Researchers at King's College London, in collaboration with European research institutes ICFO (Barcelona) and AMOLF (Amsterdam), have succeeded in mapping how light behaves in complex photonic materials inspired by nature, like iridescent butterfly wings. Scientists have broken the limit of light resolution at the nanoscale and delivered a fundamental insight into how light and matter interact, which could lead to the development of enhanced bio-sensors for healthcare and more efficient solar cells and displays.
