COX-2 expression is marker for cancer development in some benign breast biopsies
The research team discovered women whose atypia tissue expressed COX-2 enzymes were more likely to develop breast cancer subsequently, and that the more the enzyme expressed, the higher the risk. (2008-03-11)

Yale scientists create artificial 'cells' that boost the immune response to cancer
Using artificial cell-like particles, Yale biomedical engineers have devised a rapid and efficient way to produce a 45-fold enhancement of T cell activation and expansion, an immune response important for a patient's ability to fight cancer and infectious diseases, according to an advance on line report in Molecular Therapy. (2008-02-26)

Johns Hopkins researcher leads international effort to create 'proteinpedia'
A researcher at the Johns Hopkins Institute of Genetic Medicine has led the effort to compile to date the largest free resource of experimental information about human proteins. Reporting in the February issue of Nature Biotechnology, the research team describes how all researchers around the world can access this data and speed their own research. (2008-02-07)

Wikimedia Foundation and UNU-MERIT announce first survey of Wikipedians
The Wikimedia Foundation and UNU-MERIT -- a joint research and training centre of UN University and Maastricht University -- will conduct a comprehensive survey of Wikipedia's online readers and contributors. The study will shed a revealing light on the success of the world's largest collaborative reference project. (2008-01-24)

Drug industry spends nearly twice as much on marketing than on research and development
The pharmaceutical industry spends almost twice as much on the marketing and promotion of drugs than on research and development, according to a new analysis in this week's PLoS Medicine. (2008-01-02)

Indigenous water frogs under threat
Indigenous water frogs can be crowded out by immigrant or imported species. This is the finding of a Franco-German study. The scientists investigated water frog populations in France and Northern Spain and noticed that the marsh frog (Rana ridibunda), which normally occurs only in Eastern Europe, has the potential to crowd out indigenous species like Graf's hybrid frog (Rana grafi) and the Iberian water frog (Rana perezi).

Dartmouth researchers confirm the power of altruism in Wikipedia
Dartmouth researchers looked at the online encyclopedia Wikipedia to determine if the anonymous, infrequent contributors, the Good Samaritans, are as reliable as the people who update constantly and have a reputation to maintain. (2007-10-17)

ORNL's SensorPedia targets national security mission
SensorPedia, a writeable Web site in development at Oak Ridge National Laboratory, solves a huge problem by giving emergency responders and decision-makers access to data from diverse sensor networks in near real time. (2007-10-04)

Researchers discover master metabolism regulator with profound effect on fat metabolism
Researchers have discovered an enzyme that has an unexpectedly profound impact on fat metabolism. The enzyme is a master regulator that controls metabolic responses to a deficiency of essential amino acids in the diet. The research could lead to treatments for obesity and malnutrition and to preventions for type 2 diabetes and heart attacks. (2007-02-06)

How to leak a secret and not get caught
It may get a lot safer to leak sensitive documents about unethical behavior by governments or organizations if a new online service goes ahead. WikiLeaks, which hopes to launch in February, is designed to allow anyone to post documents on the Web site without the fear of being traced and thrown into jail. The Web site will exploit an anonymizing protocol which routes data through servers that use cryptography to safeguard the user's identity. (2007-01-11)

Global Text Project aims to create free, Wiki-based textbooks for developing nations

Snakes' virtual glasses, leopard spots and all-optical transistors
Virtual lenses for infrared snake sight, how the leopard gets (and changes) its spots, a major breakthrough in optical micro-circuitry, and the advantages of multiple choice testing in college. (2006-08-07)

Constructal theory predicts global climate patterns in simple way
A unifying physics principle that describes design in nature predicts, in surprisingly straightforward fashion, the basic features of global circulation and climate, according to researchers at Duke University's Pratt School of Engineering and the University of Evora in Portugal. They said the new approach to climate may have important implications for forecasting environmental change. (2006-02-08)
