A review by Canadian physicians suggests parents can help prevent food allergies in their children by introducing allergenic foods early. The authors show that with a few exceptions, introducing these foods between four and six months of age can safely help prevent the development of food allergies. The authors recommend exposing infants at low risk […]

Unlocking the secrets of electric eels
Videos of the electric eels in the experiment are available here, and here. (Video credit: Kenneth Catania) Electric eels use their high-voltage discharge not only to stun their prey, but to also to track it before attacking, according to new research. The eels are able to track prey in this manner without the use of […]
Transmitting resistance to malaria
Drug-resistant malaria parasites, which have so far emerged only in Southeast Asia, can infect species of mosquitoes found in Africa, according to a new study. If the drug-resistant parasites spread to the African mosquito species it could potentially damage global efforts to eradicate malaria, according to the authors. However further research is required to determine […]
Mobile testing for Sickle Cell Anemia
Testing for sickle cell anaemia may one-day be done in the field thanks to a new smartphone attachment and app. Sickle cell anaemia is a hereditary blood disorder commonly found in individuals of African descent, and can cause organ damage, and increase the risk of stroke and death. Researchers created an attachment for their smartphones […]
How the Emperor stays warm: Secrets of the emperor penguin
Researchers have discovered how the emperor penguin withstands the cold temperatures of Antarctica. The secret is in their down, and a specific type of feather called the plumule. The plumule, one of four types of feathers on a penguin, has previously been overlooked as an important part of the insulation. Studying three emperor penguins, researchers […]
The perfect temperature for productivity
Rising temperatures from climate change will slow economic productivity, and if left unchecked will lower the average global wage by 25 per cent by 2100, according to a new study. Economic productivity peaks at 13 ºC, and declines at lower or higher temperatures, according to a review of global economic data from the World Bank. […]
The Nature of Chernobyl
At the site of the Chernobyl disaster, animals are thriving, according to findings from a long-term census. Researchers found populations of native wildlife, such as elk, deer, boars, and wolves, have bounced back, reaching a population size similar to nearby nature reserves. The researchers note that this growth in population occurred at a time when […]
Beauty really is in the eye of the beholder
Beauty really is in the eye of the beholder, or at least partly, according to new findings. While there are indeed some universal aspects of attractiveness, such as symmetry, they believe that the uniqueness of an individual’s facial preferences is determined by experiences with friends and peers, past partners, as well as social and popular […]
Using the benefits of climate change to convince non-believers
Motivating people to take action on climate change, regardless of their existing beliefs, can be done by communicating the social benefits of acting in a climate-friendly way, according to researchers. Communicating development benefits (such as economic and scientific advancement) and the benevolence benefits (such as a more moral and caring community) helped to motivate people […]
You catch more flies with a frog’s tongue
Frogs capture their prey with the flick of a sticky tongue, and now new research is showing just how the tongue can be as sticky as adhesive tape. Now, by filming frog tongues at high-speed, researchers have captured, for the first time, how the tongue manages to immediately adhere to different surfaces. The video showed […]
Civilian deaths from weapons in the syrian conflict
Syrian children and women are disproportionately affected by explosive weapons in populated areas, and their use “should be urgently prohibited” according to the authors of a new study. These weapons include shelling, air bombardment, and car bombs. The research team examined over 78,000 civilian violent deaths that occurred in Syria from March 2011, to January […]
Rethinking Canadian TB screening
Canada’s current practice of screening all newly arriving immigrants for tuberculosis (TB) is inefficient according to new research. The authors believe screening should focus only on immigrants arriving from countries with high TB rates. Researchers found that immigrants arriving in Ontario between 2002 and 2011 came from 214 countries, however all cases of active TB […]
The Angelina Jolie effect
Media coverage of Angelina Jolie’s double mastectomy lead to an increased awareness of options for reconstructive breast surgery. Researchers compared responses to two surveys asking women questions on breast cancer and surgery, one conducted pre-Jolie’s announcement in March 2013, the other post-announcement in June 2013. Original research paper published in CANCER on September 28, 2015. Names and affiliations […]
Top predators protecting trapped ocean carbon
Over-harvesting top level predators from the oceans and coastal habitats could have far-reaching consequences on the carbon cycle and diminish our ability to offset climate change. Coastal vegetation, such as seagrasses and mangroves, are more efficient at capturing and storing carbon than tropical rainforests, and account for more than half of the ocean’s carbon storage […]
How a wine gets it’s unique flavour
The terroir of a wine, or the flavour that arises from the environment in which it’s produced, is affected by the types of microbe in the vineyard and the yeasts used during the fermentation process according to a new study. Using six genetically different populations of a microbe, S. cerevisiae, from six wine growing regions, […]
Teaching a paraplegic to walk
For the first time a person with complete paralysis in both legs (paraplegia), arising from a spinal cord injury, was able to walk without relying on manually controlled robotic limbs. The results show that brain-controlled walking can be restored after a complete spinal cord injury. After undergoing mental training, and physical rehabilitation to restore the […]
