Why seniors forget negative events

It turns out there's a scientific reason why older people tend to see the past through rose-coloured glasses.

Researchers create new family of fluorescent probes called hydrocyanines to detect reactive oxygen species in vivo

Researchers have created a new family of fluorescent probes called hydrocyanines that can be used to detect and measure the presence of reactive oxygen species.

New imaging technique allows simultaneous tracking of gene expression and movement

Flies expressing green fluorescent protein (GFP) in their retina cells or other tissues can be tracked by specially modified video cameras, creating a real time computer record of movement and gene expression.

Narrow-band imaging comparable to white light colonoscopy in differentiating colorectal polyps

Researchers from Yale University School of Medicine compared narrow-band imaging (NBI) without high magnification to standard white light colonoscopy in differentiating colorectal polyps during real-time colonoscopy and found that NBI was not more accurate than white light colonoscopy.

Computer-aided detection (CAD) mammography for breast cancer screening

Computer programs designed to help radiologists could identify more cases of breast cancer, but they might also increase the number of false-positive results, which can lead to biopsies in healthy women, according to a recent systematic review.

Single adult stem cell can self-renew in a mammal

The first demonstration that a single adult stem cell can self-renew in a mammal was reported at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

New imaging system with higher resolution

Applied Precision, Inc. a leading provider of imaging, measurement, and analysis systems for the life sciences industries announced that it will introduce a new imaging system at the American Society for Cell Biology (ASCB) annual conference with twice the resolution of traditional microscopes.

Magnetic resonance imaging alternated with mammography may be best for high-risk women

Magnetic resonance imaging (MRI) alternated with mammography at six-month intervals can detect breast cancers not identified by mammography alone, a research team from The University of Texas M. D. Anderson Cancer Center will report at the 31st at the CRTC-AACR San Antonio Breast Cancer Symposium.

Mathematical models of adaptive immunity

More than five million people die every year from infectious diseases, despite the availability of numerous antibiotics and vaccines. The discovery of penicillin to treat bacterial infections, along with the development of vaccines for previously incurable virus diseases such as polio and smallpox, achieved great reductions in mortality during the mid-20th century.

Studies on imaging and tracking transplanted cells

Successfully monitoring the distribution and fate of transplanted stem cells through imaging and subsequent tracking would aid clinicians in their ability to evaluate the efficacy of transplanted cells.

Researchers find inherited genetic variation in nicotine addiction

A new study from the Abramson Cancer Center and Department of Psychiatry in the University of Pennsylvania School of Medicine shows that smokers who carry a particular version of a gene for an enzyme that regulates dopamine in the brain may suffer from concentration problems and other cognitive deficits when abstaining from nicotine - a problem that puts them at risk for relapse during attempts to quit smoking.

Early photon tomography provides clearer picture of tumors in living animals

Fluorescent molecules - i.e. substances which can be stimulated to emit light - are extremely valuable tools in biological research and medical diagnosis.

New technique may provide quicker and easier way of developing protein-based drugs

Research by a Michigan State University chemist could eventually lead to a quicker and easier way of developing protein-based drugs that are key to treating a number of diseases, including cancer, diabetes and hepatitis.

Insufficient vitamin D causes weight gain and stunts growth in girls

Even in sun-drenched California, where scientists from the McGill University Health Centre (MUHC) and the University of Southern California conducted their study, vitamin D deficiency was found to cause higher body mass and shorter stature in girls at the peak of their growing spurt.

Researchers explore neural mechanisms behind responsibility and punishment

A new study reveals that humans use different neural mechanisms for determining criminal responsibility and assigning an appropriate punishment.

3D imaging technology improves spinal surgery outcome

Using a three-dimensional (3D) image-guided system to help place screws in the spines of patients results in safe and accurate surgery with a decrease in the number of misplaced screws, and subsequent injuries, seen in more traditional operations, say neurosurgeons at Mayo Clinic in Florida.

UK's first prostate cancer patient treated using RapidArc radiotherapy

65-year-old grandfather of six, Graham McCormack has become the first cancer patient in the UK to be treated using RapidArc radiotherapy technology from Varian Medical Systems.

Researchers visualize how cells coordinate their movements

Using novel imaging, labeling, and data-analysis techniques, scientists from the California Institute of Technology (Caltech) have been able to visualize, for the first time, large numbers of cells moving en masse during some of the earliest stages of embryonic development.
