A team of scientists at the University of Chicago has developed a non-invasive laboratory technique that allows them to instantly map when genes are switching off and on in a living bacterium as it becomes exposed to antibiotics and other changes in its environment. .. . "The standard assumption has been that DNA encoding for proteins was the sole...

A novel method to measure circadian cycles

Everyone knows morning people and late-night owls. The variation in individual circadian rhythms is an anecdotal as well as experimentally verified fact. But, until now, to systematically study circadian differences (and thereby hope to rout out the underlying genetic causes), scientists have had to rely on prolonged behavioural observation. To screen for and identify circadian rhythm variation...

Errors in the measurement of global warming corrected

The effect of the sun's heat on weather balloons largely accounts for a data discrepancy that has long contributed to a dispute over the existence of global warming, according to a report by scientists at Yale University and the National Oceanic and Atmospheric Administration (NOAA). . The report, to be published in the journal Science, says that direct heat of the sun on temperature probes of th...

Plant defenses prompt bacterial countermeasure in the form of 'island' DNA excision

Seeking to catch an arms-race maneuver in action, researchers have uncovered new evidence to explain how bacteria in the process of infecting a plant can shift molecular gears by excising specific genes from its genome to overcome the host plant's specific defenses. . Throughout evolution ?in the wild and in crops cultivated by humans ?plants have developed systems for resisting the attack of mic...

DNA technique measures suitability of soil for onion crops

Nematodes, such as the stem nematode, and fungi, such as white rot, are particularly harmful for onion crops in the Netherlands: they cause rot. Soil samples are investigated to detect this; a labour-intensive and expensive operation. Together with the Laboratory for Nematology (University of Wageningen) the company Blgg has developed a molecular technique to detect the stem nematode and white ro...

ASU researchers 'wire' DNA to identify mutations

A team of ASU researchers led by Nongjian Tao and Peiming Zhang has developed a new, breakthrough technique for the detection of DNA mutations. . .. SNPs are buried in the 3 billion DNA bases of the human genome. On average, SNPs occur about once in every 1,000 DNA bases, though not every...

Scientist measures role of science's coolest player: The snow

What would the Earth be like if one fine day all the snow melted away? . Obviously, it would be a much warmer place. But what's interesting is how much warmer, says Stephen Vavrus, an associate scientist at the Center for Climatic Research at the University of Wisconsin-Madison. Working with computer-generated simulations, Vavrus found that in the absence of snow cover, global temperatures would...

Carbon nanotube absorption measured in worms, cancer cells

University of Michigan researchers have discovered how to measure the absorption of multi-walled carbon nanoparticles into worms and cancer cells, a breakthrough that will revolutionize scientists' understanding of how the particles impact the living environment. . A team led by U-M chemical engineering professor Walter J. Weber Jr. tagged multi-walled carbon nanotubes---one of the most promisin...

Expedition discovers marine treasures

An underwater mountain that forms the world's third-largest atoll has some of the richest diversity of marine life ever found in the Caribbean, according to scientists who recently explored the area. . ..

Measuring artery repair cells could become new heart disease test

A more accurate method for measuring blood levels of specialized cells that circulate in the bloodstream and repair damage to the arterial lining has been discovered by Duke University Medical Center cardiologists. These cells, known as endothelial progenitor cells (EPC), are produced in the bone marrow and travel to the site of arterial damage. . The researchers said that tests for EPCs could be...

New research finds surveys of larval-stage organisms effective for measuring marine biodiversity

There is a push to document the biodiversity of the world within 25 years. However, the magnitude of this challenge is not well known, especially when it comes to vast and often inaccessible marine environments. To date, surveys of species diversity in the world's oceans have focused on adult organisms, but new research from Boston University has found that studying marine life in its larval phas...

Control measures fail to stop spread of new H5N1 virus

A new variant of the bird flu virus H5N1 emerged in late 2005 and replaced most of the previous variants across a large part of southern China, despite an ongoing program to vaccinate poultry, according to researchers at the University of Hong Kong in collaboration with scientists at St. Jude Children's Research Hospital. . The new virus, called Fujian-like (FL), appears to be responsible for the...

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too

For years, the brain chemical dopamine has been thought of as the brain's "pleasure chemical," sending signals between brain cells in a way that rewards a person or animal for one activity or another. More recently, research has shown that certain drugs like cocaine and heroin amplify this effect ?an action that may lie at the heart of drug addiction. . .. Using sophisticated brain-scanning and...

German researchers develop first non-invasive test to measure skin aging

Physicists and medical researchers for the first time have demonstrated a new technique that non-invasively measures in real time the level of damage to the skin from sun exposure and aging, and initial results suggest that women's skin ages faster than men's. Findings appear in the October 1 issue of Optics Letters, a journal of the Optical Society of America. . This new laser-based technique i...

ASU researchers test antibacterial effects of healing clays

Clay is most commonly associated with the sublime experience of the European spa where visitors have been masked, soaked and basted with this touted curative since the Romans ruled. If ASU geochemist Lynda Williams and microbiologist Shelley Haydel's research on the antibacterial properties of clays realizes its full potential, smectite clay could one day rise above cosmetic use to take its place...
