An international team of astronomers may have set a new record in discovering what is the most distant known galaxy in the Universe. Located an estimated 13 billion light-years away, the object is being viewed at a time only 750 million years after the big bang, when the Universe was barely 5 percent of its current age.

The primeval galaxy was identified by combining the power of the NASA/ESA Hubble Space Telescope and CARA’s W. M. Keck Telescopes on Mauna Kea in Hawaii. These great obs

Team shows tumors can be triggered in normal cells by signals from nearby supporting cells

Like a detective combing the scene of a crime for clues, researchers often target their search for cancer causes in the cells known as epithelial cells. After all, it is these cells that most often become cancerous, so it makes sense to look for what goes wrong inside these cells.

However, a new report from a team of Vanderbilt-Ingram Cancer Center scientists demonstrates that tumors ca

Woodpeckers carry fungus in beaks that promotes tree decay

A new study in the journal Condor by the New York-based Wildlife Conservation Society (WCS) and Arkansas State University suggests that a woodpecker’s beak is a virtual petri dish of fungal spores that play a key role in the decay of dead trees, or “snags.”

The authors examined several species of woodpeckers living in ponderosa pine forests in northern California and Oregon, finding that over 60 percent of the sa

Draw a picture on the computer and it immediately shows up on the screen of a hand-held computer in Africa. The person with the palm computer can then use the tiny screen to access a supercomputer in France to perform advanced graphic calculations that a number of logged-on people can see simultaneously. This solution is called Verse, a new protocol for 3D graphics created by a 27-year-old with no previous knowledge of programming at the Royal Institute of Technology (KTH) in Stockholm. Verse was re

Although there are numerous telescopes – both large and small – examining the night sky at any one time, the heavens are so vast and so densely populated with all manner of exotic objects that it is extremely easy to overlook a significant random event. Fortunately, a new generation of scientific instruments is now enabling UK astronomers to prepare for the unexpected and become leaders in so-called “Time Domain Astrophysics”.

Exciting new observations of many different, time-variable celest

After years of searching for a rare African primate, anthropologist Scott McGraw and his colleagues believed that the Miss Waldron’s red colobus monkey, Procolobus badius waldroni, was probably extinct. They had written a paper in 2000 saying so.

But recent hard evidence of the Miss Waldron’s red colobus’ existence has rekindled McGraw’s hopes of finding the primate, reportedly last seen in 1978. McGraw, an associate professor of anthropology at Ohio State University, det
