New technique measures brain activity in large populations of nerve cells

Researchers have developed a new technique which allows them to measure brain activity in large populations of nerve cells at the resolution of individual cells. The technique, reported today in the journal Nature, has been developed in zebrafish to represent a simplified model of how brain regions work together to flexibly control behaviour.

Chemically altered proteins may be key to understanding memories

Having a fat head may not be a bad thing, according to new findings at The Johns Hopkins University. As reported in the February 9 issue of Neuron, researchers have made a significant discovery as to how adding fat molecules to proteins can influence the brain circuitry controlling cognitive function, including learning and memory.

UCLA creates crowd-sourced online gaming system to detect malaria

Online crowd-sourcing - in which a task is presented to the public, who respond, for free, with various solutions and suggestions - has been used to evaluate potential consumer products, develop software algorithms and solve vexing research-and-development challenges. But diagnosing infectious diseases?

JAM-A protein a far more powerful clot inhibitor: Study

Cut your toe, and platelets -- those disc-shaped cells circulating in your blood -- rush to the scene, clumping together to plug the leak. But when an unwanted clot forms in an artery, and an overaccumulation of platelets blocks blood flow, a heart attack or stroke occurs, too often with fatal results.

Competition to celebrate art in medicine

It turns out beauty really is skin deep. A hair follicle or skin specimen that doesn't look like much of anything to the naked eye can become a complex, colorful work of art under a microscope. Mayo Clinic dermatologists struck by the beauty they see in the cellular have started a competition to celebrate art in medicine. The winning entries appear in the May issue of the Journal of Cutaneous Pathology.

New clues about why immune system fails to kill tumors in mice

A pioneering approach to imaging breast cancer in mice has revealed new clues about why the human immune system often fails to attack tumors and keep cancer in check. This observation, by scientists at the University of California, San Francisco (UCSF), may help to reveal new approaches to cancer immunotherapy.

Glycolipids play an important role in intercellular signalling

In a new study, scientists at the University of Copenhagen show that a specific type of carbohydrate plays an important role in the intercellular signalling that controls the growth and development of the nervous system. In particular, defects in that carbohydrate may result in the uninhibited cell growth that characterizes the genetic disease neurofibromatosis and certain types of cancer.

Study describes structure and function of the stratum corneum

A research team at Karolinska Institutet in Sweden has succeeded in describing the structure and function of the outermost layer of the skin - the stratum corneum - at a molecular level. This opens the way not only for the large-scale delivery of drugs via the skin, but also for a deeper understanding of skin diseases.

Researchers discover how adult brain can adapt to new situations

They say you can't teach an old dog new tricks. Fortunately, this is not always true. Researchers at the Netherlands Institute for Neuroscience have now discovered how the adult brain can adapt to new situations. The Dutch researchers' findings are published on Wednesday in the prestigious journal Neuron. Their study may be significant in the treatment of neurodevelopmental disorders such as epilepsy, autism and schizophrenia.

IMPAKT 2012 breast cancer conference to focus on four major areas

"Basic science and clinical medicine move at different pace because they follow different paths. Both however aim at improving strategies to manage cancer patients. We need to efficiently translate the good things from basic science and efficiently implement them in the clinic."

P-bodies have a much broader role in controlling the activities of the cell than previously thought

Cells can reuse the chemical messengers that carry genetic information to the machinery that makes proteins. Sometimes cells shuttle the messengers to storage and later reactivate them to make proteins, according to new research.

Researchers develop small endoscopic device fitted with femtosecond laser scalpel

Whether surgeons slice with a traditional scalpel or cut away with a surgical laser, most medical operations end up removing some healthy tissue, along with the bad. This means that for delicate areas like the brain, throat, and digestive tract, physicians and patients have to balance the benefits of treatment against possible collateral damage.

Computational adaptive optics for real-time in-vivo applications

Real-time, 3-D microscopic tissue imaging could be a revolution for medical fields such as cancer diagnosis, minimally invasive surgery and ophthalmology. University of Illinois researchers have developed a technique to computationally correct for aberrations in optical tomography, bringing the future of medical imaging into focus.

Cancer therapy with common cold virus

Common viruses have become the latest weapon against cancer. There is the case of the eight-year-old African boy diagnosed with Burkitt's lymphoma at a Ugandan health clinic. He was exposed to the measles virus and in the next few weeks his tumour regressed completely and he entered remission. But only relatively recently have scientists clinically examined the interaction between viruses and cancers in the growing area of oncolytic virotherapy.

FDA draft guidance documents address use of nanotechnology by food and cosmetics industries

Two draft guidance documents that address the use of nanotechnology by the food and cosmetics industries were issued today by the U.S. Food and Drug Administration.

CPMC surgeons successfully reattach forehead and scalp of a 22-year-old Stockton woman

Surgeons at the renowned Buncke Clinic at California Pacific Medical Center, part of the Sutter Health network, have successfully reattached the forehead and scalp of a 22-year-old Stockton woman whose hair was caught in machinery at her workplace. This type of surgery is extremely rare, and has been successfully performed only a handful of times world-wide.

Breast cancer treatment and classification revolutionized in landmark study

Breast cancer treatment could be revolutionized with patients offered more accurate diagnoses and better-targeted treatments after a study in which scientists genetically charted the disease. The research found that rather than being a single disease, breast cancer can be classified into 10 distinct types. It also identified several new genes that determine the aggressiveness of the cancer.

Secondary Speckle Sensing Microscopy may rapidly and accurately diagnose malaria

Correctly and quickly diagnosing malaria is essential for effective and life-saving treatment. But rapid detection, particularly in remote areas, is not always possible because current methods are time-consuming and require precise instrumentation and highly skilled microscopic analysis. Now, a promising new optical imaging system, described in a paper published today in the Optical Society's (OSA) open-access journal Biomedical Optics Express, may make the diagnosis of this deadly disease much easier, faster, and more accurate.
