We sat down with Brookhaven theoretical physicist Raju Venugopalan for a conversation about “color glass condensate” and the structure of visible matter in the universe. Q. We’ve heard a lot recently about a “new form of matter” possibly seen at the Large Hadron Collider (LHC) in Europe — a state of saturated gluons called “color…

RHIC, the Relativistic Heavy Ion Collider at Brookhaven Lab, found it first: a “perfect” liquid of strongly interacting quarks and gluons – a quark-gluon plasma (QGP) – produced by slamming heavy ions together at close to the speed of light. The fact that the QGP produced in these particle smashups was a liquid and not…

Replication Tango

There are many complex steps to the dance of DNA replication. And scientists must learn to sway along in order to understand how both healthy and cancerous cells divide. Scientists at Brookhaven National Laboratory have begun to learn how to follow the complex molecular choreography by which intricate cellular proteins recognize and bind to DNA…

  This guest post was written by Ernie Lewis, an atmospheric scientist at Brookhaven Lab, who is leading a year-long climate study aboard two Horizon Lines cargo ships, the Spirit and Reliance. He recently returned from a preliminary “cruise” from L.A. to Hawaii and back aimed at assessing conditions for deploying instruments aboard the ships…

This guest post was written by Brookhaven Lab physicist Kostas Nikolopoulos. Today’s public seminar at CERN, where the ATLAS and CMS collaborations presented the preliminary results of their searches for the Standard Model (SM) Higgs boson with the full dataset collected during 2011, is a landmark for high-energy physics! The Higgs boson is a still-hypothetical…

This is not a story about the latest mega cruise ship, with five swimming pools, 10 restaurants, a rock-climbing wall, and a casino. The vessel we’re talking about, the Horizon Spirit, will be outfitted instead with radars, aerosol sampling devices, and other high-tech tools. But even without the fancy umbrella drinks, Ernie Lewis, an atmospheric…

This guest post was written by Mona S. Rowe, science writer for Brookhaven National Laboratory’s National Synchrotron Light Source (NSLS) and NSLS-II. The quest to authenticate an unknown Rembrandt painting, titled “Old Man with a Beard,” hit a dramatic high at the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory. Using an advanced x-ray…

This guest post was written by Pat Looney, chair of the Sustainable Energy Technology Department at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory. If the sun is shining over Long Island, NY, as you read this article, the Long Island Solar Farm (LISF) is generating enough clean solar energy to power as many…

This guest post was written by Brookhaven Lab science writing intern Kenrick Vezina, who will be sharing Brookhaven science stories from inside and outside laboratories on site through mid December. I’m about to enter the well-worn, vegetation-free (read: tick-free) pathway that cuts through the forest near my dorm. I’m about two steps down the trail…

Here’s a recipe for basic chemistry: Mix a bunch of stuff in a reaction vessel and see what happens. Only you don’t really see the action taking place — unless you have some way to…
