In the future, consumers may be adding a powerful “spice” to their food that could save lives. Researchers in Canada are developing a natural antibody cocktail that can help prevent the most common foodborne germs, including E. coli and Salmonella, which cause thousands to become sick or die each year in this country.

Derived from freeze-dried egg yolk, the substance is nicknamed a spice because it can be sprinkled or sprayed onto meats, fruits and vegetables to complement existing sanitati

Sascha Abramson has been investigating new methods to ensure that polymer medical implants in the human body don’t fail. Abramson looked at degradable polymers, ones the body can ultimately absorb, to gain a deeper understanding of how and why their structures change – crucial parts of a puzzle that must be solved for polymers to perform predictably and successfully in medical implants.

Her research was conducted as a postdoctoral associate at Rutgers’ New Jersey Center for Biomaterials in

Intriguing Structural Strategy Aims at Making Designer Plastics Affordable

The future was supposed to be “plastics,” according to advice given in a 1960s movie The Graduate. Many a company thought that future meant the gradual ascendancy of “designer” or specialty plastics, but almost 40 years later the market is still dominated by plastics that can be manufactured cheaply in bulk.

Six researchers from the University of California at Santa Barbara (UCSB) and one at Helsinki U

Scientists studying trees ranging from saplings to 130 years old in Canada’s northern forests have discovered that the period since a fire last swept through an area determines how much carbon the forest can store. Twenty to forty year old stands absorb more carbon than those 70 years old and older, despite being smaller and having less biomass or plant material.

Boreal or northern forests account for close to 25 percent of total carbon stored in vegetation and soils in the Earth’s biospher

Inhaled glucocorticoid drugs are more effective than the newer anti-leukotriene tablets for adults with mild or moderate asthma, concludes a study in this week’s BMJ.

Professor Francine Ducharme reviewed 13 trials comparing leukotriene receptor antagonists with low doses of inhaled glucocorticoids for 28 days or more in children and adults.

She found that adults treated with leukotriene receptor antagonists were 60% more likely to suffer worsening of symptoms, whereas those treated

University of Minnesota researchers have made the first-ever hardness measurements on individual silicon nanospheres and shown that the nanospheres’ hardness falls between the conventional hardness of sapphire and diamond, which are among the hardest known materials. Being able to measure such nanoparticle properties may eventually help scientists design low-cost superhard materials from these nanoscale building blocks.

Up to four times harder than typical silicon-a principal ingredient o
