Wheat can fatally starve insect predators

...mpounds like this chitin-binding lectin that don't cost the plant much to produce, unlike producing poisons and stronger walls. Those inducible defenses use a lot of a plant's energy that could be used toward growth and reproduction." The scientists currently are looking for regulatory regions in Hessi...

Rapid, Low-Cost DNA Testing

...el electrophoresis. Each test takes 1 hour and can cost as much as $1.00. Setting up a lab for gel electrophoresis requires a capital expenditure of $5,000. By contrast, Professor Rothberg's technique only requires 5 minutes, and it costs approximately $0.05 (literally five cents) per test. The capital ex...

In 2005, the overall cost of patients' time spent on cancer care was $2.3 bi... the last year of life. "For 2005, the estimated cost for the initial phase of care alone was approximately $2.3 billion," the authors write. These estima...

Red flag for repetitive stress injuries identified for first time in humans

...hird of missed workdays in the United States, at a cost of $20 billion a year in workers' compensation. In previous studies, the researchers pinpointed these early warning signals in a rat model of RMI. The current study is the first to identify the warning signals in humans. For the study, they re...

Leeches ferry infection among newts

...em to fight off the disease. But that comes at the cost of having fewer offspring," he adds. Findings from the study may also indicate that human activities could lead to increases in the infection, since these leeches are most abundant in wetlands with lots of aquatic vegetation.

In a map of a simulated open-office plan, the tool graphically displays real-time calculations of the "Speech Privacy Index," a quantitative measure of how much speech can be heard in a given environme...

High-dose anticlotting drug cuts heart attack, death risk in half

Without the ice, the bears generally cannot get anywhere near these fast swimming marine mammals. Another t...

Experts predict Tamiflu could halve the pandemic influenza death toll versus no intervention

...hen compared to no intervention. This equates to a cost saving of $70,000 per 1,000 population which would save $21 billion in the US alone versus no intervention. Adding other strategies such as school closures further reduces the attack and death rate and provides a health benefit at a reasonable cost. ...

Mutating the entire genome
