Screening for breast cancer and the early detection of other tumors one day may be as simple as spitting into a collection tube or cup, according to recent studies by UCLA researchers.

In one early study based on a risk model, presented here at the 96th Annual Meeting of the American Association for Cancer Research, the UCLA scientists reported that genetic “biomarkers” isolated in saliva predicted oral squamous cell carcinoma in about nine out of 10 cases.

A recent stud

Imagine a computer system that can automatically search through videos of football matches and pull out all the shots on goal or all the fouls.

Creating the elements that make such a system possible is a key result from the IST BUSMAN project. The current generation of computer systems is excellent at searching for and manipulating text: as the spectacular success of Google has shown. However, computers are now routinely used to store and process more than just text – videos of

A fundamental number that affects the color of light emitted by atoms as well as all chemical interactions has not changed in more than 7 billion years, according to observations by a team of astronomers charting the evolution of galaxies and the universe.

The results are being reported today (Monday, April 18) at the annual meeting of the American Physical Society (APS) by astronomer Jeffrey Newman, a Hubble Fellow at Lawrence Berkeley National Laboratory representing DEEP2, a

ESA’s SMART-1 mission to the Moon has been monitoring the illumination of lunar poles since the beginning of 2005, about two months before arriving at its final science orbit.

Ever since, the AMIE on-board camera has been taking images which are even able to show polar areas in low illumination conditions. Images like these will help identify if peaks of eternal light exist at the poles.

SMART-1 took views of the North Polar Region from a distance of 5000 km during a paus

Understanding the interaction of Fragile X mental retardation protein and kissing complex RNAs

Fragile X syndrome is the most common inherited form of mental retardation, affecting approximately 1 in 3600 males and 1 in 4000-6000 females. Fragile X syndrome results from loss of expression of the Fragile X mental retardation protein (FMRP), the product of the FMR1 gene. Now, Drs. Robert and Jennifer Darnell and colleagues, from The Rockefeller University, report the uncovering of

Research could lead to new drugs for HIV

The increased frequency of drug resistance in isolates of the AIDS virus, HIV, makes identification of new antiviral targets an urgent necessity. Host genes required to support the replication of HIV are a potential source of such novel targets, but relatively few appropriate target genes have been identified in animal cells thus far. A new study, conducted by Dr. Suzanne Sandmeyer and colleagues at the University of California, reports t
