Canadian discoveries pivotal to science of toxins, illness associated with E. coli

Many Canadian scientists and clinicians were unsung heroes during the early years (1977–1983) of research unfolding around verotoxigenic E. coli (VTEC). In an article published today, a clinician and medical microbiologist documents the history of this area of study, focusing on the key discoveries and major contributions made by Canadians to the science of what many people refer to as "hamburger disease."

How fat could help solve part of the diabetes problem

The pancreas is a large organ that wraps around our gut, and produces the exact amount of insulin our bodies need when we eat -- except when we start to develop diabetes, and insulin production slows down. Scientists describe how a fat recycling system within pancreatic "beta cells" determines the amount of insulin they secrete, and so may provide a target for future diabetes therapies.

Geneticists map human resistance to AIDS

The key to future HIV treatment could be hidden right in our own genes. Everyone who becomes infected deploys defense strategies, and some even manage to hold the virus at bay without any therapy at all. Scientists retraced the entire chain of events in these battles, from the genome of the virus to the genome of the victim, and have published their results.

Earthworms invade New England

At least sixteen species of earthworms are now found in Vermont and elsewhere in New England. All are exotic and many are invasive. As they spread, they devour organic matter, disrupting forests and releasing carbon dioxide. But they also store carbon deep in the soil. So, do the worms, on balance, slow or accelerate climate change? Vermont researchers are on the case.

'Molecular Velcro' may lead to cost-effective alternatives to natural antibodies

Taking inspiration from the human immune system, researchers have created a new material that can be programmed to identify an endless variety of molecules. The new material resembles tiny sheets of Velcro, each just 100 nanometers across. But instead of securing your sneakers, this molecular Velcro mimics the way natural antibodies recognize viruses and toxins, and could lead to a new class of biosensors.

Warm winters let trees sleep longer

In the temperate zones, vegetation follows the change of the seasons. Researchers have now brought a new correlation to light: The colder the winter, the earlier native plants begin to grow again. Since warmer winters can be expected as the climate changes, the spring development phase for typical forest trees might start later and later -- giving an advantage to shrubs and invasive trees that don't depend on the cold.

Vibrating micro plates bring order to overcrowded radio spectrum

GSM, WiFi, Bluetooth, 4G, GPS: a smartphone already has to handle many wireless standards. And this number will only increase further. There are still no good filters to keep all those future standards separate. Researchers have now taken an important step with a new type of filter, based on micromechanics.

Understanding the difference between 'human smart' and 'computer smart'

Considering 798 to be an odd number is endemic to human cognition, reveals a new study. A common assumption in the cognitive sciences is that thinking consists of following sets of rules (as it does in a computer). A recent research argues that unlike digital computers, which are designed to follow rules, the computations performed by the neural networks that make up our brain are inherently context dependent. People sometimes make seemingly strange mistakes like thinking that 798 is an odd number despite knowing how to identify odd and even numbers.
