Humans ignore motion and other cues in favor of a fictional stable world

Would you notice if all the objects around you simultaneously moved farther away? In a virtual-reality laboratory in Oxford, researchers have obtained the puzzling finding that humans can be "blind" to changes like this.

Using neural growth factor could allow researchers to mass produce stem cells for treatment of disease

Human embryonic stem cells (hES) offer great hope for the treatment of some devastating diseases, but finding a way to keep enough of these cells usable and healthy for transplantation in patients has been an ongoing problem.

Oddly shaped DNA can cause DNA breaks in mammalian cells

When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma, according to a study by researchers at The University of Texas M. D. Anderson Cancer Center.

Potential new drug for treating all forms of tuberculosis

An experimental tuberculosis drug may be effective against not only multi drug-resistant forms of the disease but could also be the first compound to treat the latent stage of infection as well. Researchers reported their results at the 2006 ASM Biodefense Research Meeting.

Interleukin-15 encourages CD8+ T cells to proliferate and reduces their tolerance to tumor antigens

Certain types of white blood cells assist the body in destroying cancerous tumors. Among these are CD8+ T cells. The T is for thymus, the gland near the base of the throat that both raises up and weeds out blood cells involved in immune responses.

New system accurately predicts mortality of older Americans

Researchers at the San Francisco VA Medical Center have created an index that is 81 percent accurate in predicting the likelihood of death within four years for people 50 and older.

New system for analyzing how drugs bind to proteins

Researchers at Florida State University's National High Magnetic Field Laboratory and Scripps Florida have developed and evaluated a robust new system for analyzing how drugs bind to proteins. This groundbreaking work could speed the delivery of potential new drugs and improve existing ones.

New compound CDDO-Im protects against the development of liver cancer

Researchers have identified a new compound called CDDO-Im that protects against the development of liver cancer in laboratory animals.

Scientists map brain area that may help find human brain stem cells

A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells.

Genome data may contain small but significant errors

Since the genome sequence of the bacterial pathogen Haemophilus influenzae was published in 1995, the genetic code of many other large, complex, medically, and commercially significant organisms including humans has also been elucidated

Global warming may be reducing respiratory illnesses

Rising global temperatures over the past two decades may be responsible for a shortened season of a serious respiratory illness in the United Kingdom, according to an article in the March 1 issue of Clinical Infectious Diseases.

Advancing knowledge of diet-gene interactions

Josi Ordovas, PhD, director of the Nutrition and Genomics Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University joined more than eighty other leading researchers in the fields of nutrition and genetics to co-author a report outlining their strategy for maximizing the impact of nutrigenomics research on global poverty and health.

FOLFOX now treatment standard for colorectal cancer in the United States

One of the newest and most potent chemotherapies for colon cancer is as safe and effective for the elderly as it is for younger patients, based on a University of North Carolina at Chapel Hill-led data review.

Emerging infectious agents pose new risks for people with bleeding disorders

An international team of scientists, including a hematologist from Thomas Jefferson University in Philadelphia, has concluded that people with bleeding disorders such as hemophilia remain at risk from emerging infectious agents in plasma and blood transfusions. For this reason, recombinant therapies, that is, those produced in the laboratory, must always be an option

Brain scans may detect neurological decline in normal people

Brain scans may detect neurological changes in people who exhibit no outward signs of cognitive decline but who later develop dementia or mental impairment, according to the results of a new study led by researchers at the University of California, Berkeley.

Research may help explain Alzheimer's memory loss

Based on laboratory research, scientists at Georgetown University Medical Center have a new theory as to why people with Alzheimer's disease have trouble performing even the simplest memory tasks, such as remembering a family member's name.

New way to culture adult stem cells from bone marrow

In a significant advance for regenerative medicine, researchers at Rice University have discovered a new way to culture adult stem cells from bone marrow such that the cells themselves produce a growth matrix that is rich in important biochemical growth factors.
