Magnetic nanotechnology holds promise in fighting cancer

Detecting cancer and reinventing computing are two challenges that seemingly have little, if anything, to do with each other. That is, unless you are a nanotechnologist like Shan Wang, an associate professor of materials science and engineering and of electrical engineering at Stanford.

Muscles burn lactic acid as well as carbos

In the lore of marathoners and extreme athletes, lactic acid is poison, a waste product that builds up in the muscles and leads to muscle fatigue, reduced performance and pain.

Discovery points to more effective ways of regulating cell signalling

A discovery made at The Walter and Eliza Hall Institute provides new insights into enhancing the function of the protein SOCS3, which regulates the response of cells to external stimuli.

Scientists gain greater understanding of how embryos differentiate left from right

Researchers at the Forsyth Institute have discovered a new mechanism responsible for early left/right patterning, the process by which organs locate themselves on the left or right side of the body.

New research links metabolism and appetite suppression, opening door to obesity treatments

A team led by a Canadian researcher has discovered a process by which a small protein acts directly within muscles to increase the body's metabolism to burn fat while simultaneously suppressing appetite.

New finding provides researchers with renewable source for macrophages and neutrophils

A new approach to generating large quantities of two types of white blood cells that are critical for destroying invading bacteria, viruses and other pathogens in humans has been developed by researchers at the University of California, San Diego (UCSD) School of Medicine.

Calcium supplements may be little help for healthy kids

There's little question that most kids get too little calcium, but a new review of evidence casts doubt on the value of supplements and calcium-fortified foods to build stronger bones.

Promising treatment for Huntington's disease soon to be tested clinically

At the Institut Curie, CNRS and Inserm researchers have shown that cysteamine, which is already used to treat a rare disease called cystinosis, prevents the death of neurons in Huntington's disease. Like Alzheimer's and Parkinson's, Huntington's disease, is characterized by the abnormal death of neurons.

St. Jude develop strategy to speed future development of more effective and less toxic treatments for medulloblastoma

Investigators at St. Jude Children’s Research Hospital have developed a strategy to speed future development of more effective and less toxic treatments for medulloblastoma, a type of brain cancer. Medulloblastomas arise in the back of the brain and account for about 20 percent of childhood brain tumors.

Researchers develop model to assess prostate cancer risk

Researchers have developed a model to predict prostate cancer for men who undergo a prostate biopsy. The details of the risk calculator appear in the Journal of the National Cancer Institute.

Calcium supplementation for improving bone mineral density in children

There's little question that most kids get too little calcium, but a new review of evidence casts doubt on the value of supplements and calcium-fortified foods to build stronger bones.

Short acting insulin analogues versus regular human insulin in patients with diabetes mellitus

Fast-acting artificial insulin drugs work just as well as regular human insulin, but it's unclear how they could affect the health of people with diabetes over the long run, according to a new review of recent studies.

miR 155 overexpression can lead to cancer

Scientists in the Ohio State University Comprehensive Cancer Center say that just one, single, malfunctioning microRNA is sufficient to cause cancer in mice.

Researchers develop system for observing nuclear motion

The cell is understood to be highly organized, with specialized areas for different functions and molecular motors shuttling components around.

Genetic switch that links animal growth and cancer

Laboratory discoveries by scientists at two universities may lead to new directions in cancer therapy drugs. The researchers have discovered that a genetic switch involved in growth and development of an animal is the same one used to prevent normal cells from becoming cancerous.
