JLab’s 100th Experiment Explores Quark Behavior in QCD

The experiment, titled “Quark Propagation through Cold QCD Matter,” began its run in December 2003 and wrapped up in early March. It probed Quantum Chromodynamics (QCD), a fundamental theory of particle physics that describes the interactions of quarks and gluons — the basic building blocks of matter. A property of QCD, called confinement, states that no quark can ever be found alone. Instead, quarks combine in pairs or triplets to make up larger particles. For instance, every proton and neutron cont

17th Century Solar Mystery Linked to Global Cooling Unveiled

Hundreds of Maunder minimum stars are not, say UC Berkeley astronomers

A mysterious 17th century solar funk that some have linked to Europe’s Little Ice Age and to global climate change, becomes even more of an enigma as a result of new observations by University of California, Berkeley, astronomers.

For 70 years, from 1645 until 1714, early astronomers reported almost no sunspot activity. The number of sunspots – cooler areas on the sun that appear dark against the brig

NASA researchers customize "lab-on-a-chip" technology to help protect future space explorers and detect life forms on Mars

With a microscope and computer monitor, researchers at NASA’s Marshall Space Flight Center in Huntsville, Ala., watch fluorescent bacteria flow through tiny, fluid highways on a dime-sized lab on a chip.

Lab-on-a-chip technology allows chemical and biological processes — previously conducted on large pieces of laboratory equipment — to be performed on a small glass plate with fluid channels, known to scientists as microfluidic capillaries.

Realistic Avatars: Enhancing Online Interaction and E-Commerce

Animated characters on the Internet are often soulless. They stare, speak monotonously and have limited facial expression. More realistic characters are being tested by a European team of researchers. Could such enhanced characters benefit e-commerce and build better Web-based communities?

Most of us interact with our computers by punching keys. But the time is ripe for a more sophisticated and realistic interface. One way forward is to program characters known as avatars. They can be given

’Music2Titan’: sounds of a spaceprobe

When ESA’s Huygens spaceprobe, travelling on board NASA’s Cassini spacecraft en route to Saturn, lands on the planet’s largest moon Titan in January 2005, not only will it carry a variety of scientific instruments, but also music ‘made in Europe’.

Four musical themes composed by French musicians Julien Civange and Louis Haéri were placed on board ESA’s Huygens probe in October 1997. After a seven-year and 4000 million kilometre journey, the music will reach Titan on 14 January 200

Weeds as Medicine: Unlocking Health Benefits in Your Backyard

Unwanted, pulled or poisoned, the lowly weed is sometimes better than its highly touted “herbal” cousins for preventing and curing a host of diseases, according to University of Florida research.

“If I had one place to go to find medicinal plants, it wouldn’t be the forest,” said John Richard Stepp, a UF anthropologist who did the study. “There are probably hundreds of weeds growing right outside people’s doors they could use.”

Uncovering Life on Mars: New Innovations in Biomarker Detection

Is there – or has there ever been – life on Mars? A UK project could help provide the answer to this fascinating question.

The team are working to improve the equipment on space probes which is used to try and identify evidence of life on other planets.

The work is focusing on the development of more effective and robust systems for detecting ’biomarkers’. (’Biomarkers’ are molecules that indicate the existence of current or extinct life.)

Earth Has ‘Blueberries’ Like Mars – ‘Moqui Marbles’ Formed in Groundwater in Utah’s National Parks

Even before marble-shaped pebbles nicknamed “blueberries” were discovered on Mars by the Opportunity rover, University of Utah geologists studied similar rocks in Utah’s national parks and predicted such stones would be found on the Red Planet.

In a study published in the June 17 issue of the journal Nature, the Utah researchers suggest both the Martian and Utah rocks – known as hematite concretions – formed underground when minerals precipitated from flowing groundwater.

Grad Students Explore Cutting-Edge Research in East Asia & Australia

American students are happy to find jobs during the summer to help pay for their schooling. Others are more fortunate to be part of intern programs that prepare them for their eventual professional lives. For some others, however, the summer prospects are even more rewarding. How about an opportunity to construct carbon nanotubes in a Sydney, Australia laboratory? What about the chance to study with a molecular virologist in Taipei to search for a potential HIV cure? Or maybe do research based on a f

Common ’signature’ found for different cancers

Discovery yields hope for universal treatment

Researchers at the University of Michigan, Johns Hopkins and the Institute of Bioinformatics in India have discovered a gene-expression “signature” common to distinct types of cancer, renewing hope that a universal treatment for the nation’s second leading killer might be found.

Scientists essentially abandoned the search for a common approach to cancer therapy after research launched by the 1970s “War on Cancer” revealed the

Old Massive Galaxies Found in Young Universe’s Early Stages

Very Large Telescope Unravels New Population of Very Old Massive Galaxies

Current theories of the formation of galaxies are based on the hierarchical merging of smaller entities into larger and larger structures, starting from about the size of a stellar globular cluster and ending with clusters of galaxies. According to this scenario, it is assumed that no massive galaxies existed in the young universe.

However, this view may now have to be revised. Using the multi-mode F

How worms’ noses sense oxygen

Organisms ranging from bacteria to humans navigate environments that can contain dangerously too little or too much oxygen. Yet, scientists know little about how animals sense oxygen levels around them.

Researchers from the Berkeley and San Francisco campuses of the University of California have now discovered how the nematode C. elegans senses oxygen levels in order to steer clear of surrounding areas that are too low or too high in oxygen.

In the process, the researchers also di

Unraveling Autoimmune Diseases: Genetic Insights and Innovations

Autoimmune diseases are quite complex and this is due to the fact that these illnesses do not depend on just one gene. Thus, in order to find a suitable treatment, it is not enough to identify a gene involved in the development of the disease – each and every one has to be identified. To this end, a number of strategies have been design; for example, many geneticists have begun to analyse the genetic differences between healthy individuals and ill ones.
