Counting tumor cells in blood predicts treatment benefit in prostate cancer
Counting the number of tumor cells circulating in the bloodstream of patients with castration-resistant prostate cancer can accurately predict how well they are responding to treatment, new results show.   view more (2008-07-07)

News from Cancer: Risk factors for deadly form of lymphoma
A new study indicates that the incidence of mantle cell lymphoma, an aggressive type of non-Hodgkin's lymphoma, is on the rise, most frequently striking men, Caucasians and older individuals.   view more (2008-07-07)

Small protein may have big role in making more bone and less fat
A small protein may have a big role in helping you make more bone and less fat, researchers say.   view more (2008-07-02)

Researchers link early stem cell mutation to autism
In a breakthrough scientific study published today in the Proceedings of the National Academy of Sciences, scientists at the Burnham Institute for Medical Research have shown that neural stem cell development may be linked to Autism.   view more (2008-07-01)

New efficiency benchmark for dye-sensitized solar cells
In a paper published online June 29 in the journal Nature Materials, EPFL professor Michael Graetzel, Shaik Zakeeruddin and colleagues from the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences have achieved a record light conversion efficiency of 8.2% in solvent-free... view more (2008-06-30)

How to build a plant
Walking through a tropical or temperate forest immediately impresses us with the myriad forms and soaring structures of the plant world, but our knowledge of how plants are actually built, cell by cell, is still incomplete.   view more (2008-06-26)

Researchers identify promising cancer drug target in prostate tumors
Scientists at Dana-Farber Cancer Institute report they have blocked the development of prostate tumors in cancer-prone mice by knocking out a molecular unit they describe as a "powerhouse" that drives runaway cell growth.   view more (2008-06-26)

Cellular annoyance
The results of a multi-national survey to be published in the International Journal of Mobile Communications reveals some surprises about cell phone use that have implications for organizations that rely on mobile communications.   view more (2008-06-25)

Alzheimer's disease as a case of brake failure?
Rutgers researcher Karl Herrup and colleagues at Case Western Reserve University have discovered that a protein that suppresses cell division in brain cells effectively "puts the brakes" on the dementia that comes with Alzheimer's disease (AD). When the brakes fail, dementia results.   view more (2008-06-25)

Blue light used to harden tooth fillings stunts tumor growth
A blue curing light used to harden dental fillings also may stunt tumor growth, Medical College of Georgia researchers say.   view more (2008-06-25)

Nerve cells derived from stem cells and transplanted into mice may lead to improved brain treatments
Scientists at the Burnham Institute for Medical Research have, for the first time, genetically programmed embryonic stem (ES) cells to become nerve cells when transplanted into the brain, according to a study published today in The Journal of Neuroscience.   view more (2008-06-25)

Crucial Factors in Lymphoma Development and Survival Discovered
Researchers at National Jewish Medical and Research Center have discovered an important factor in the development of B-cell lymphomas, one of the fastest growing forms of cancer.   view more (2008-06-24)

Viruses hitch a ride in the cell
Viruses can travel around cells they infect by hitching a ride on a microscopic transport system, according to new research. Cells are exposed to foreign DNA and RNA and it is understood that some of this genetic material can be integrated into the host genome. Using modern microscopic techniques,... view more (2008-06-24)

Refusal of suicide order: Why tumor cells become resistant
Cells with irreparable DNA damage normally induce programmed cell death, or apoptosis. However, this mechanism often fails in tumor cells so that transformed cells are able to multiply and spread throughout the body.   view more (2008-06-24)

New paradigm for cell-specific gene delivery
Researchers from Northwestern University and Texas A & M University have discovered a new way to limit gene transfer and expression to specific tissues in animals.   view more (2008-06-23)

New source of heart stem cells discovered
Researchers at Children's Hospital Boston are continuing to document the heart's earliest origins. Now, they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes, or heart muscle cells.   view more (2008-06-23)

Predicting the risk of a common fungal infection after stem cell transplantation
In silico genetic analysis in mice has led to the discovery of a gene affecting susceptibility to a severe fungal infection in transplant recipients.   view more (2008-06-20)

Gene mutation improves leukemia drug's effect
Gene mutations that make cells cancerous can sometimes also make them more sensitive to chemotherapy. A new study led by cancer researchers at Ohio State University shows that a mutation present in some cases of acute leukemia makes the disease more susceptible to high doses of a particular... view more (2008-06-18)

Penn researchers find key developmental pathway activates lung stem cells
Researchers from the University of Pennsylvania School of Medicine found that the activation of a molecular pathway important in stem cell and developmental biology leads to an increase in lung stem cells. Harnessing this knowledge could help develop therapies for lung-tissue repair after injury or... view more (2008-06-18)

MIT researchers see alternative to common colorectal cancer drug
A compound that accumulates in cells more readily than a commonly used colorectal cancer drug may be just as useful in treating colorectal tumors, but with fewer side effects, MIT researchers have found.   view more (2008-06-18)

Experimental anti-cancer synthetic molecule targets tumor cell growth and angiogenesis
A recent study conducted by three French CNRS (Centre National de la Recherche Scientifique) laboratories describes a new candidate anti-cancer drug, named HB-19.   view more (2008-06-18)

Effective treatment for sickle cell underused by doctors
Uncertainties about proper use and possible long-term effects of hydroxyurea in the treatment of sickle cell anemia may be wrongly influencing doctors to avoid prescribing it to those in serious need, according to results of a literature review by specialists at Johns Hopkins.   view more (2008-06-18)

Ability to track stem cells in tumors could advance cancer treatments
Using noninvasive molecular imaging technology, a method has been developed to track the location and activity of mesenchymal stem cells (MSCs) in the tumors of living organisms.   view more (2008-06-17)

Wealth of genomic hotspots discovered in embryonic stem cells
In a paper published in Cell on June 13, 2008, Singapore scientists at the Genome Institute of Singapore (GIS) and the National University of Singapore (NUS) unveil an atlas that showing the location of "genomic hotspots" of essential protein "switches" (transcription factors)... view more (2008-06-16)

How Montezuma gets his revenge
Every year, about 500 million people worldwide are infected with the parasite that causes dysentery, a global medical burden that among infectious diseases is second only to malaria.   view more (2008-06-16)
