Odds slim to none that global warming natural

It doesn’t matter how you cut the numbers, 
human activity is behind it

An analysis of temperature data since 1500 all but rules out the possibility that global warming in the industrial era is just a natural fluctuation in the Earth’s climate, according to a new study by McGill University physics professor, Shaun Lovejoy.

Country life and concussions

Motorized sport accidents are the most common cause 
of concussions among rural kids

Researchers at Western University in London, Ont. have found youth living in rural areas are more likely to suffer concussions from injuries involving motorized vehicles such as all-terrain vehicles and dirt bikes, whereas youth living in urban areas suffer concussions mostly as a result of sports. Hockey accounts for 40 per cent of those injuries.


Goat

Goats are smarter than you think

They are independent learners with long memories

Goats learn how to solve complicated tasks quickly and can recall how to perform them for at least 10 months, which might explain their remarkable ability to adapt to harsh environments, say researchers at Queen Mary University of London. Scientists trained a group of goats to retrieve food from a box using a linked sequence

Human development linked with spread of invasive plants

One invasive species leads to another, says an article published in the current issue of Rangeland Ecology & Management.

Cows learn better with a buddy

Calves housed individually took longer to adapt to new things

Cows learn better when housed together, which may help them adjust faster to complex new feeding and milking technologies on the modern farm, a University of British Columbia study has found. The research, published in PLOS ONE, shows dairy calves become better at learning when a “buddy system” is in place. The study also provides

Ordinary conditioner works as well as anything

It happens. A call from the school or daycare sets off a frenzy of shampooing, combing and various delousing efforts that has the whole family feeling creepy. Female head lice lay eggs directly onto strands of hair, and they cement them in place with a glue-like substance, making them incredibly hard to remove. In fact,



Research proves it — living in the country is better

Research proves it — living in the country is better

Living in the country improves your mental health, say researchers writing in the American Chemical Society journal Environmental Science & Technology. Mathew P. White and colleagues note that mental well-being is a major public health issue, with unipolar depressive disorder the leading cause of disability in middle- to high-income countries. Some research suggests that part

Paying kids to eat veg

Researchers at Brigham Young and Cornell universities say the good news is that a new U.S. government rule has schools serving an extra $5.4 million worth of fruits and vegetables each day. The bad news is that a study shows the kids discard 70 per cent of it. “We saw a minor increase in kids
