Strong test for FUR

A new spectroscopic method has been developed for the determination of the drug furosemide used to treat congestive heart failure and other conditions. The drug is alsosed illegally by some athletes as a stimulant and rapid weight-loss agent.Yali Liu, Huijuan Wang, Jian Wang and Yuanfang Li of Southwest University, in Chongqing, China, explain how furosemide […]

Pumping bacterial toxins

In a previous issue, we discussed early work on Escherichia coli as a proof of principle for understanding how bacterial resistance to antibiotics can emerge. Now, Edward Yu’s team at Iowa State University have taken another step forward in our understanding of this pressing issue by using crystallography to reveal the structure of a protein […]

1000 disease protein structures

An interdisciplinary study hinging on X-ray crystallography and nuclear magnetic resonance studies has examined 1000 proteins from more than 40 different human pathogens, including those responsible for plague, anthrax, salmonella, cholera, tuberculosis, leprosy, amoebic dysentery and influenza. Researchers at the Center for Structural Genomics of Infectious Diseases (CSGID) and the Seattle Structural Genomics Center for […]

Helical light

Researchers have known for some time of monochromatic light beams, such as Laguerre-Gauss beams, which carry orbital angular momentum also have a helical phase profile. According to Ole Steuernagel of the University of Hertfordshires Science and Technology Research Institute, UK, have helical wave fronts and can be made visible using interferometry. Such dark helices can […]

Algae burn for you

Finding sustainable alternatives to fossil fuels that would both solve the problem of dwindling supplies of oil and cut the net carbon dioxide emissions from vehicles running on hydrocarbon fuels is a cause high on the environmental agenda. The use of biomass as a source for fuels compounds has benefits, but the setting aside of […]

Notre Dame researchers demonstrate new DNA detection technique

Notre Dame researchers demonstrate new DNA detection technique – A team of researchers from the University of Notre Dame have demonstrated a novel DNA detection method that could prove suitable for many real-world applications. Physicists Carol Tanner and Steven Ruggiero led the team in the application of a new technique called laser transmission spectroscopy (LTS). […]
