By American Society for Cell Biology

By fitting a "smart" mobile phone with magnifying optics, researchers created a real "cell" phone. a diagnostic-quality microscope for clinics in developing countries as well as American biology classrooms.

Rationing soft drink sizes: A good public health move for Canada, experts argue 2013-01-25

By Canadian Medical Association Journal

New York City's limit of a maximum 16-ounce size of sugar-sweetened drinks for sale in eating establishments is a positive public health move and should be replicated in Canada, argues a new editorial.

Immune cells use tethered slings to avoid being swept away 2013-01-25

By American Society for Cell Biology

Neutrophils, critical components of the immune system's response to bacteria and other pathogens, throw out tube-like tethers that act as anchor points, controlling their speed as they roll along the walls of blood vessels during extremely fast blood flow

Genetic manipulation of urate alters neurodegeneration in mouse model of Parkinson's disease 2013-01-25

By Massachusetts General Hospital

Investigators report that mice with a genetic mutation increasing urate levels were protected against the kind of neurodegeneration that underlies Parkinson's disease, while the damage was worse in animals with abnormally low urate. Their findings add fur

New study better explains racial disparities in strokes 2013-01-25

By University of Alabama at Birmingham

Researchers say a 10-millimeter difference in blood pressure is associated with an 8 percent increase in stroke risk for white people, but a 24 percent increase in stroke risk for black people.

Surviving sepsis with LECT2 2013-01-25

By Rockefeller University Press

Failure to launch an adequate immune response may be at the root of septic shock, according to a new study.

Re-engineered optogenetic switches allow direct measurement of complex cellular systems 2013-01-25

By American Society for Cell Biology

A chemical biology lab has re-engineered optogenetic switches so that switches run backward, firing bursts of fluorescent light that reveal newly detailed patterns of electrical activity in neural networks, beating cardiac cells and developing embryos.

Autoimmune disease: Retraining white blood cells 2013-01-25

By Ecole Polytechnique Fédérale de Lausanne

Symptoms of an autoimmune disease disappeared after a team of scientists retrained the white blood cells involved using a specially engineered protein. This method is extremely promising for treating diseases such as type I diabetes and multiple sclerosis

To revert breast cancer cells, give them the squeeze 2013-01-25

By University of California - Berkeley

Researchers have found that compression can guide malignant breast cells back to a normal growth pattern. The findings demonstrate the influence of mechanical forces on a cell's destiny.

People without spouses under-represented in Alzheimer's clinical trials 2013-01-25

By American Academy of Neurology (AAN)

A new study suggests that people without a spouse are represented less in Alzheimer's disease clinical trials compared to people with spouses.

Improving the development of new cancer models using an advanced biomedical imaging method 2013-01-25

By Society for Experimental Biology and Medicine

Scientists have demonstrated that an advanced magnetic resonance imaging method can non-invasively evaluate the cellular proliferation of tumor models of breast cancer. This quantitative imaging method evaluates the diffusion of water in tumor tissue, whi

Why our backs can't read braille: Scientists map sensory nerves in mouse skin 2013-01-25

By Johns Hopkins Medicine

Scientists have created stunning images of the branching patterns of individual sensory nerve cells. Their report details the arrangement of these branches in skin from the backs of mice.

GOOOAAALLL! What soccer can teach health researchers 2013-01-25

Health researchers can learn from soccer to create high-quality studies that recognize complexities in health interventions.

Should physicians prescribe cognitive enhancers to healthy individuals? 2013-01-25

By Institut de recherches cliniques de Montreal

Physicians should not prescribe cognitive enhancers to healthy individuals, states a new report. The authors provide their recommendation based on the professional integrity of physicians, the drugs' uncertain benefits and harms, and limited health care r

New window on Parkinson's disease: Metallic probe proves able to detect fibrils from misfolded proteins in real time 2013-01-25

By Rice University

Scientists discover a new molecular probe to track aggregated fibroids inside living cells that cause Parkinson's disease.

New form of cell division found: Natural back-up mechanism during faulty cell division 2013-01-25

By University of Wisconsin-Madison

Researchers have discovered a new form of cell division in human cells. They believe it serves as a natural back-up mechanism during faulty cell division, preventing some cells from going down a path that can lead to cancer.

Scientists developing quick way to ID people exposed to ionizing radiation 2013-01-25

By DOE/Lawrence Berkeley National Laboratory

A new study could lead to a blood test that detects if a person has been exposed to radiation, measures their dose, and separates people suffering from inflammation injuries -- all in a matter of hours. They identified eight DNA-repair genes in human bloo

PRT versus IMRT toxicity in Medicare beneficiaries with prostate cancer 2013-01-25

By Journal of the National Cancer Institute

There is no difference between proton radiotherapy and intensity-modulated radiotherapy when comparing the toxicity among Medicare beneficiary patients with prostate cancer at 12 months post-treatment, according to a new study.
