Winter health and safety tips

Winter is a special time for celebration. It should also be a time for added caution if you or someone in your family is an older adult. It is the season for falls, slips on icy streets, and other dangers that can be especially harmful for older adults. "Something as simple as a fall can be devastating for older men and women," says Dr. Evelyn Granieri, director of the Division of Geriatrics at NewYork-Presbyterian Hospital/The Allen Hospital. "Before the cold weather arrives, it is important to prepare."

Scientists discover a way to accurately map typhoid outbreaks in the city

In the mid-nineteenth century, John Snow mapped cases of cholera in Soho, London, and traced the source of the outbreak to a contaminated water pump. Now, in a twenty-first century equivalent, scientists funded by the Wellcome Trust working in Kathmandu, Nepal, have combined the latest in gene sequencing technology and global positioning system (GPS) case localisation to map the spread of typhoid and trace its source.

One in six mobile phones home for E. coli: Study

The London's School of Hygiene and Tropical Medicine released a study in conjunction with the Queen Mary, University of London which suggests that Britons are not doing a good enough job of washing hands. Experts said the most likely reason for the potentially harmful bacteria festering on so many gadgets was people failing to wash their hands properly with soap after going to the toilet.

Scientists conclude pesticide contamination as a major problem in Europe

Pesticides are a bigger problem than had long been assumed. This is the conclusion of a study in which scientists analysed data on 500 organic substances in the basins of four major European rivers. It was revealed that 38 per cent of these chemicals are present in concentrations which could potentially have an effect on organisms.

ASU scientists receive USDA grants to combat food-related illness

Roughly 1 in six Americans are sickened every year by food-borne ailments, according to the Centers for Disease Control and Prevention. The effects of these illnesses range from acutely unpleasant to lethal, and the problem may be getting worse, as our food supply becomes more global, with an increasing number of antibiotic-resistant pathogens.

Thermo Fisher Scientific cassette cuts tissue embedding time in half

Thermo Fisher Scientific Inc., the world leader in serving science, today introduced the Thermo Scientific SecureSette, a new cassette for histology laboratories that reduces embedding time by 50 percent. The innovative design of new SecureSette™ cassettes makes embedding extremely simple; tissues are orientated during grossing and the cassette is not opened during embedding. An integral sponge securely holds tissue in place during processing which not only improves orientation, but also reduces the time spent re-embedding incorrectly aligned samples by more than half. The result is a more efficient workflow, higher quality and improved patient safety without the need to purchase additional equipment.
