Particle physics study finds new data for extra Z-bosons and potential fifth force of nature

The Large Hadron Collider is an enormous particle accelerator whose 17-mile tunnel straddles the borders of France and Switzerland. A group of physicists at the University of Nevada, Reno has analyzed data from the accelerator that could ultimately prove or disprove the possibility of a fifth force of nature.

Evidence of the 'Lost World' -- did dinosaurs survive the end Cretaceous extinctions?

The Lost World, Sir Arthur Conan Doyle's account of an isolated community of dinosaurs that survived the catastrophic extinction event 65 million years ago, has no less appeal now than it did when it was written a century ago. Various Hollywood versions have tried to recreate the lost world of dinosaurs, but today the fiction seems just a little closer to reality.

Targeted agent shows promise in biliary cancer study

COLUMBUS, Ohio - An experimental agent has shown promising results in people with advanced biliary cancer, according to a multi-institutional clinical trial led by cancer researchers at the Ohio State University.

The agent, known as AZD6244 (ARRY-142886), blocks certain enzymes that cancer cells need to proliferate and survive.

Large study documents how p53 mutations link to high-grade breast cancer, poor outcomes

Denver, Colo. - In what is believed to be the largest study of its kind in the US, researchers have found that almost 26 percent of women studied who have breast cancer have mutations in a gene important in controlling cell growth and death, and that patients with mutations in this gene - known as p53 - had poorer outcomes including a significantly increased risk of death from the cancer.

Clouds: Lighter than air but laden with lead

RICHLAND, Wash. -- By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. The results suggest that lead generated by human activities causes clouds to form at warmer temperatures and with less water.

Study shows simple writing assignment improves minority student grades

In a follow-up to a 2006 study, a University of Colorado at Boulder researcher and his colleagues found that an in-class writing assignment designed to reinforce students' sense of identity and personal integrity increased the grade-point averages of African-American middle school students over a two-year period, and reduced the rate at which these students were held back or placed in remediati

Novel CU-Boulder technique shrinks size of nanotechnology circuitry

A University of Colorado at Boulder team has developed a new method of shrinking the size of circuitry used in nanotechnology devices like computer chips and solar cells by using two separate colors of light.

Tropical forest seed banks: A blast from the past

LIVERMORE, Calif. -- Seeds of some tree species in the Panamanian tropical forest can survive for more than 30 years before germinating.

That is 10 times longer than most field botanists had believed.

Making a point: Picoscale stability in a room-temperature AFM

Forget dancing angels, a research team from the National Institute of Standards and Technology (NIST) and the University of Colorado (CU) has shown how to detect and monitor the tiny amount of light reflected directly off the needle point of an atomic force microscope probe, and in so doing has demonstrated a 100-fold improvement in the stability of the instrument's measurements under ambient c
