From Quark Soup to Atoms and Stars

YadavAtSTAR.jpeg

Scientists using the atom smasher at the U.S. Department of Energy’s Brookhaven National Laboratory have observed a phase transition different than the smooth transition of the early universe from the hot “soup” of subatomic particles to the atoms, made up of neutrons, protons and electrons that are the building blocks of matter.

Photo: Tiger Beetle’s Chase Highlights Mechanical Law

TigerBeetle-Chase-Pattern.jpg

If an insect drew a line as it chased its next meal, the resulting pattern would be a tangled mess. But there’s method to that mess: It turns out the tiger beetle, known for its speed and agility, does an optimal reorientation dance as it chases its prey at blinding speeds.

Sensitive Detection Method May Help Impede Illicit Nuclear Trafficking

JAP-Deinert-Detection-UT.jpg

According to a new study in the Journal of Applied Physics, coupling commercially available spectral X-ray detectors with a specialized algorithm can improve the detection of uranium and plutonium in small, layered objects such as baggage. This approach may provide a new tool to impede nuclear trafficking.

Groundbreaking Optical Device Could Enhance Optical Information Processing, Computers

3Dimage.jpg

At St. Paul’s Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. Researchers at Washington University in St. Louis have used the same phenomenon to build an optical device that may lead to new and more powerful computers that run faster and cooler.

Tracking the Transition of Early-Universe Quark Soup to Matter-as-We-Know-It

ScienceFig1_rev0414.jpg

By smashing together ordinary atomic nuclei at the Relativistic Heavy Ion Collider (RHIC), scientists recreate the primordial soup of the early universe thousands of times per second. Using sophisticated detectors to track what happens as exotic particles emerge from the collision zone and “freeze out” into more familiar forms of matter, they are turning up interesting details about how the transition takes place.
