Vanderbilt-Ingram Cancer Center researchers have identified six subtypes of an aggressive and difficult-to-treat form of breast cancer, called "triple-negative breast cancer (TNBC)." In the July issue of the Journal of Clinical Investigation, Cancer Center Director Jennifer Pietenpol, Ph.D., and colleagues describe the molecular features of these six distinct subtypes and identify chemotherapies to which the different subtypes respond in cultured cells and animal tumor models. Knowing the specific subtype could help physicians determine which therapies would work best ...

CHAMPAIGN, Ill. — With the threats of cybercrime, cyberterrorism and cyberwarfare looming over our hyper-connected world, the best defense for the U.S. might be a good offense, says new research by a University of Illinois expert in technology and legal issues. Law professor Jay P. Kesan warns that an active self-defense regime, which he terms "mitigative counterstriking," is a necessity in cyberspace, especially to protect critical infrastructure such as banking, utilities and emergency services. "The threats from cyber-attacks are real, and the harm of a potential ...

Researchers from the University of Georgia Odum School of Ecology have found that certain neotropical stream ecosystems rely almost entirely on a single fish species known as the banded tetra for the critical nutrient phosphorus. In a paper recently published in the journal Ecology, the researchers, led by Gaston E. "Chip" Small, explain why this particular species plays such a crucial role—and why these stream systems are vulnerable as a result. "I initially set out to understand how different physiological factors—diet, fish elemental composition, stream chemistry—interacted ...

Boulder, Colorado, USA - July GSA Today science article authors Peter W. Reiners of the University of Arizona and colleagues have developed and successfully carried out a novel, extraordinary technique for learning how efficiently river channels cut and increase local topographic relief: They have used the exposure of "clinker" deposits in combination with highly refined dating techniques. Clinkers are baked coals; baking naturally occurs in shallow depths (tens of meters) and when the clinkers are exhumed during erosion and the development of topographic relief, they are ...

A tiny doughnut-shaped laser is the latest marvel of silicon microminiaturization, but instead of manipulating bits it detects very small particles. Small particles play a big — and largely unnoticed — role in our everyday lives. Virus particles make us sick, salt particles trigger cloud formation, and soot particles sift deep into our lungs and make it harder to breathe. The sensor belongs to a category called whispering gallery resonators, which work like the famous whispering gallery in St. Paul's Cathedral in London, where someone on the one side of the dome can hear ...

To maintain and improve their market competitiveness, small and midsized businesses are turning to focused analytics that help them manage today's vastly greater information flows, operate more efficiently and make better decisions, new benchmark research from Ventana Research finds.

However, the research indicates that despite viewing them as valuable and important, small and midsize businesses are maturing only slowly in ...

PULLMAN, Wash.—Some baseball superstitions are accepted as cold, hard truth. But in the world of physics, the most accepted verities are subject to experimentation. A corked bat hits the ball further? Not in Lloyd Smith's lab. Baseballs today are livelier than in the past? See above. Storing balls in a humidor can curb home run production? We'll grant you that one, but only because Smith has fired the balls through a cannon and measured their bounciness as they hit a bat. Smith, an associate professor of in Washington State University's School of Mechanical and Materials ...

LOS ANGELES (June 27, 2011) – A simple item found in almost every medicine cabinet – a cotton swab -- may be a key tool in the fight against post-surgical wound infections. In a sentinel trial, Cedars-Sinai Medical Center surgeon Shirin Towfigh, MD, showed that painless and gentle probing of a wound with a dry cotton swab after surgery dramatically reduced infections in post-operative incision sites: only 3 percent of patients who had the daily probings contracted infections compared to 19 percent of those who didn't -- a rate more than six times higher than that of ...

CSIRO research has revealed that the tremendous diversity of ladybird beetle species is linked to their ability to produce larvae which, with impunity, poach members of 'herds' of tiny, soft-bodied scale insects from under the noses of the aggressive ants that tend them.Reconstructing the evolutionary history of ladybird beetles (family Coccinellidae), the researchers found that the ladybirds' first major evolutionary shift was from feeding on hard-bodied ("armoured") scale insects to soft-bodied scale insects. "Soft-bodied scales are easier to eat, but present a whole ...

OAK BROOK, Ill. – Researchers may have discovered one reason that African Americans are at increased risk for heart attacks and other cardiovascular events. According to a new study published online in the journal Radiology, African Americans have increased levels of non-calcified plaque, which consists of buildups of soft deposits deep in the walls of the arteries that are not detected by some cardiac tests. Non-calcified plaque is more vulnerable to rupturing and causing a blood clot, which could lead to a heart attack or other cardiovascular event. According to ...

OAK BROOK, Ill. – Breast cancer screening with mammography results in a significant reduction in breast cancer mortality, according to long-term follow-up results of a large-scale Swedish trial. The results are published online in the journal Radiology. "Mammographic screening confers a substantial relative and absolute reduction in breast cancer mortality risk in the long-term," said Stephen W. Duffy, M.Sc., professor of cancer screening at Queen Mary, University of London. "For every 1,000 to 1,500 mammograms, one breast cancer death is prevented." The Swedish Two-County ...

PHILADELPHIA — Patients treated with sunitinib and sorafenib responded to the flu vaccine, which suggests the agents do not damage the immune system as much as previously feared, according to a study in Clinical Cancer Research, a journal of the American Association for Cancer Research. Keith Flaherty, M.D., director of developmental therapeutics at the Massachusetts General Hospital and a senior editor of Clinical Cancer Research, said the findings have broad implications beyond questions of patient management.
