A MOM AND A DAIRYMAN PLEAD: DON’T FEED
Two years ago, when Oregon parents Jill Brown and Jason Young met Brad and Tricia Salyers, the families had no idea that they would eventually be sharing in a tragedy that sickened four of the Salyers’ children and left Brown and Young’s youngest child, Kylee – 23 months old at the time – with such...

Diagnosis Just a Breath Away With New Laser
University of Adelaide physics researchers have developed a new type of laser that will enable exciting new advances in areas as diverse as breath analysis for disease diagnosis and remote sensing of critical greenhouse gases. They have been able to produce 25 times more light emission than other lasers operating at a similar wavelength - opening the way for detection of very low concentrations of gases. Research has shown that with various diseases, minute amounts of gases not normally exhaled can be detected in the breath; for example, acetone can be detected in the breath when someone has diabetes..Continue Reading
A Faster Way to Flag Bacteria-Tainted Food — and Prevent Illness
On the horizon is a new approach for pathogen screening that is far faster than current commercial methods. Scientists are reporting the technique in the ACS journal Analytical Chemistry. Sibani Lisa Biswal and colleagues note that Salmonella is one of the pathogens most commonly associated with foodborne illness, which can cause fever, diarrhea and abdominal cramps. They used an array of tiny “nanomechanical cantilevers,” anchored at one end, kind of like little diving boards. The cantilevers have peptides attached to them that bind to Salmonella. When the bacteria bind to the peptides, the cantilever arm bends, creating a signal. The screening system rapidly distinguished Salmonella from other types of bacteria in a sample. One of the peptides was even more specific than an antibody, Continue Reading
Stem Cell Lines Not Fit for Clinic
Most stem cell lines registered with the NIH don’t comply with the FDA’s guidelines for human use, according to a new report. Many of the stem cell lines used by academics and registered with the U.S. National Institutes of Health (NIH) would not be eligible for commercialization because they don’t pass muster with the Food and Drug Administration (FDA), the agencies’ standards throws up a potential roadblock on the path from the laboratory to the clinic. “The main concern . How do we move this technology [to the clinic]? How do we translate it?”.Continue Reading
