Discovery of 480 genes that control human cell division

A team of U.S., Israeli and German scientists used computational biology techniques to discover 480 genes that play a role in human cell division and to identify more than 100 of those genes that have an abnormal pattern of activation in cancer cells.

Carnegie Mellon study identifies where thoughts of familiar objects occur inside the human brain

A team of Carnegie Mellon University computer scientists and cognitive neuroscientists, combining methods of machine learning and brain imaging, have found a way to identify where people's thoughts and perceptions of familiar objects originate in the brain by identifying the patterns of brain activity associated with the objects.

Protein fingerprinting made easy

Combining some traditional experimental methods of molecular biology with computational methods of artificial intelligence, a group of researchers from Ruder Boskovic Instititute and Faculty of Natural Sciences and Mathematics from Zagreb, Croatia, demonstrated a novel approach for producing 'protein fingerprints' of diverse tissues.

First map of imprinted genes in human genome

Scientists at Duke University have created the first map of imprinted genes throughout the human genome, and they say a modern-day Rosetta stone – a form of artificial intelligence called machine learning – was the key to their success.

Researchers improve accuracy of breast cancer prognoses

One of the many unknowns facing women who are diagnosed with breast cancer is predicting the likelihood that the cancer will spread to other parts of the body – metastasize.

Cancer death rate decline doubling

A new report from the nation's leading cancer organizations shows cancer death rates decreased on average 2.1 percent per year from 2002 through 2004, nearly twice the annual decrease of 1.1 percent per year from 1993 through 2002.

Equine flu highlights issue of biosecurity

Not long before the equine flu outbreak, Dr Phil McManus from the University of Sydney School of Geosciences sent out an Australia-wide questionnaire to thoroughbred horse breeders. He asked them what they thought was the biggest threat to their industry.

People may need more dietary choline than previously thought

A new study published in the May issue of the American Journal of Clinical Nutrition indicates that the current recommended Adequate Intake (AI) for choline may, in fact, be inadequate for some people.

Researchers identify genetic markers associated with breast cancer tumor grade and lymph node metastases

Researchers have identified genetic markers on several chromosomes in the tissue surrounding tumor cells that are associated with breast cancer tumor grade and the presence of lymph node metastases, according to a study in the May 16 issue of JAMA.

Nutritional benefits of egg consumption

Nine studies presented at the Experimental Biology 2007 meeting support the growing body of research on the nutritional benefits of egg consumption, including its promotion of weight loss and its role in providing choline, an essential nutrient often lacking in the diet that promotes brain and memory development and function.

Advanced age associated with poorer bladder cancer-specific survival in radical cystectomy patients

Traditional wisdom taught in urological residency has been that healthy octogenarians with bladder cancer may be offered radical cystectomy without a significantly increased incidence of postoperative complications.

Faster diagnosis of early-stage Alzheimer's disease

Research by faculty and staff at Rowan University, Glassboro, N.J.; the University of Pennsylvania School of Medicine; and Drexel University may lead to better diagnosis of early-stage Alzheimer's disease.

Breakthrough in photoswitchable fluorescent protein science

University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were able to keep the lights turned off for up to 65 hours.

MIT model helps see how folds develop and decay in the cerebral cortex

Large mammals--humans, monkeys, and even cats--have brains with a somewhat mysterious feature: The outermost layer has a folded surface. Understanding the functional significance of these folds is one of the big open questions in neuroscience.

Computer model behaves like humans on visual categorization task

Computers can usually out-compute the human brain, but there are some tasks, such as visual object recognition, that the brain performs easily yet are very challenging for computers.

Halting neurogenesis improves working memory in mice

New research from Columbia University Medical Center may explain why people who are able to easily and accurately recall historical dates or long-ago events, may have a harder time with word recall or remembering the day's current events.

How does the highly pathogenic bird flu virus spread to new countries?

Might the domestic bird trade be responsible? Or is it wildfowl? Since last year, a team from CIRAD has been working on wildfowl. To date, the virus has not been detected in healthy wild birds, but many dead or dying birds have been found near infection foci.
