There are lots of new ideas out there for giving you extra protection against chronic diseases through the food you eat. But many good ideas may never make it to market. Researchers at the University of Guelph, led by Brian McBride, have found a way to enrich milk with docosahexaeonic acid (DHA)–an essential nutrient that many people are lacking. Researchers at the University of Manitoba, led by Rotimi Aluko, discovered that certain protein fragments from yellow field pea seeds can...

In 1997, a forest fire in Indonesia ignited an area of peatlands that smouldered for months. By the time it was over, the fire had released greenhouse gases equal to 20 to 40 percent of the total worldwide emissions that year from fossil fuels. But that could be a drop in the bucket compared to future emissions from peat fires. Indonesian peatlands are dwarfed by Canada's. The total area of all peatland in Canada is estimated to be about twice the size of Saskatchewan. At this week's...

European-based speakers representing the fields of nuclear energy, genetically modified organisms, and harm reduction science in tobacco made the plea on 18 February at the Annual Meeting of the American Association for the Advancement of Science held in Vancouver, Canada. The panelists, each with pertinent experience of real-life scientific support to policy-making, offered first-hand advice on best practices and pitfalls when architecting science policy on both sides of the Atlantic. The 18...

Visualizations Help Communities Plan For Sea-level Rise
2012-02-20 04:00:08

Researchers at the University of British Columbia have produced computer visualizations of rising sea levels in a low-lying coastal municipality, illustrating ways to adapt to climate change impacts such as flooding and storms surges. The researchers are working with a municipality south of Vancouver, Canada that is surrounded by water on three sides and is expecting the sea-level to rise by 1.2 meters by 2100 — a change that would affect a number of waterfront homes, inland suburban...

Pulsars: The Universe's Gift To Physics
2012-02-20 04:22:53

Pulsars, superdense neutron stars, are perhaps the most extraordinary physics laboratories in the Universe. Research on these extreme and exotic objects already has produced two Nobel Prizes. Pulsar researchers now are poised to learn otherwise-unavailable details of nuclear physics, to test General Relativity in conditions of extremely strong gravity, and to directly detect gravitational waves with a "telescope" nearly the size of our Galaxy. Neutron stars are the remnants of massive...

Sound Illusion May Have Been Inspiration For Stonehenge
2012-02-18 05:05:58

There have been many theories behind the creation of Stonehenge, including some believing the ancient structure was originally intended to be a monument, a calendar, an observatory, or a place for healing or worship. Now, an American researcher has proposed yet another theory -- that the legendary 5,000-year-old stone circle in southern England may have been an attempt to mimic or recreate an auditory illusion. According to LiveScience Senior Writer Stephanie Pappas, the theory was put...

Canada Excellence Research Chair determines how marine ecosystems in the Arctic are responding to climate change Marcel Babin, Canada Excellence Research Chair in Remote Sensing of Canada's New Arctic Frontier at the Université Laval, will be discussing his research on the effects of environmental changes in the Arctic as part of an upcoming press breakfast panel discussion. The February 17 Canada Press Breakfast on the Arctic and oceans will be part of the 178th annual...

Seven Dutch women suffering from osteoporosis received bone-strengthening medication from implanted microchips as part of a first-of-its kind study of wirelessly controlled drug-releasing devices, according to research published Thursday in the journal Science Translational Medicine. According to Lauran Neergaard of the Associated Press (AP), the study, which was funded by Massachusetts-based implantable drug delivery device developer MicroCHIPS, Inc and headed up by MIT professors Robert...

Marine protected areas (MPAs) may turn out to be in the wrong place at the wrong time. As a result of changing conditions, marine species have been on the move with observed shifts of as much as three kilometres per year over the past 50 years, and forecasts of shifts of as much as 300 kilometres in the coming 50 years. Decisions on where to put MPAs weren't always made with a changing climate in mind. That has researchers asking how these areas–meant to protect...

According to a new study co-authored by SFU communication professor Adam Holbrook, national, provincial and local economic development policy makers need to pay closer attention to Vancouver´s uniqueness as a space for economic innovation. Holbrook and Brian Wixted, another study co-author, say: “Vancouver must build on its economic, social and natural advantages. Otherwise, Vancouver could lose its global edge as an innovator in the development of knowledge-based high tech...

Science is a weekly peer-reviewed academic journal of the American Association for the Advancement of Science (AAAS). It was founded by New York journalist John Michaels in 1880 with financial support from Thomas Edison and later from Alexander Graham Bell. Because of limited success the journal ceased publication in March 1882, only to be reestablished a year later by entomologist Samuel H. Scudder who was able to keep the journal going until 1894, when it was sold to psychologist James...
