Listeria :: Simple equations track Listeria trails
Circles, slaloms, figure eights, and loop-the-loops ? biologists studying the motion of Listeria monocytogenes sensed that these paths were related, but they didn?t have a good way to define what fit in and what didn?t. A remarkably simple new mathematical description, published online in the Proceedings of the National Academy of Sciences [Abstract], reproduces all these shapes with just one pair of equations and only two key variables.
Cancer :: Research says boiling broccoli ruins its anti-cancer properties
Researchers at the University of Warwick have found that the standard British cooking habit of boiling vegetables severely damages the anticancer properties of many Brassica vegetables such as broccoli, Brussel sprouts, cauliflower and green cabbage.
Food :: Food and drink, and what it says about us
What did the Vikings eat for supper? How good were the grocers in Roman Pompeii? What was it like feasting with the Greeks in the second millennium BC? How can this tell us why we like TV dinners today?
Obesity :: Obesity increases risk of injury on the job
Having a body mass index (BMI) in the overweight or obese range increases the risk of traumatic workplace injury, according to researchers at the Johns Hopkins Bloomberg School of Public Health’s Center for Injury Research and Policy. Employer-sponsored weight loss and maintenance programs should be considered as part of a well-rounded workplace safety plan.
SARS :: Getting to the core of an emergent public health threat
The outbreak of severe acute respiratory syndrome (SARS) in 2002 was a loud wake-up call for researchers studying infectious diseases. SARS infected over 8,000 people, killed 10 percent of those infected, and weakened most with pneumonia.
Cholesterol :: Women less likely than men to have their cholesterol controlled
Women are significantly less likely than men to have their LDL cholesterol controlled to recommended levels, according to a new study by the National Committee for Quality Assurance (NCQA).
Health :: Smokeless cannabis delivery device efficient and less toxic
A smokeless cannabis-vaporizing device delivers the same levels of THC, the active therapeutic chemical, with the same biological effects as smoking cannabis without the harmful toxins created by burning cannabis, according to UCSF researchers.
Imaging :: NMR advance relies on microscopic detector
Detecting the molecular structure of a tiny protein using nuclear magnetic resonance (NMR) currently requires two things: a million-dollar machine the size of a massive SUV, and a large sample of the protein under study.
Mental Health :: New tool to shed light on, improve teen mental health services
Can you imagine an archer trying to improve her accuracy by practicing blindfolded, never seeing how close she was to hitting her target, never getting any information to help correct her aim”
