Controlling Ebola outbreak in West Africa most effective way to decrease international risk

Controlling the Ebola virus outbreak at the source in West Africa is the most effective way to decrease international risk of transmission, a new study of global airline travel patterns shows. The authors used a model that predicts that three people infected with Ebola are predicted to fly from West Africa (Guinea, Liberia, and Sierra […]

Got milk? No? Check your vitamin D

Children who drink rice, almond, soy or goat’s milk have lower levels of vitamin D in their blood than those who drink cow’s milk, according to a new study. Canadian regulations stipulate that every 100 millilitres of cow’s milk must be fortified with 40 International Units of vitamin D, non-cow’s milk is not subject to […]

Religious reminders could quell hostility

A new study suggests that reminding someone of their religious beliefs could help quell hostile urges. Christian, Jewish, Muslim and Hindu participants were exposed to either threatening experiences (such as thinking about their own death or failing at an academic assignment) or not. They were then given a chance to judge and assign punishments for […]

Gamers can be quick learners

A new study suggests that while people who play video games don’t necessarily have better sensorimotor skills than non-gamers, they are significantly faster at learning sensorimotor tasks. A group of 18 gamers and 18 non-gamers were asked to complete a task that involved keeping a cursor in the centre of a moving target. When the […]

Senegal is now Ebola-free

On Friday, October 17, the World Health Organization declared that Senegal is now free of Ebola virus transmission. Senegal had a single case of Ebola in late August. All those who contacted the patient have now completed the 21-day monitoring period are are symptom free and tested negative for the virus. A similar announcement about […]

In areas where predators keep down populations of herbivores like impala, acacia trees flourish. A lack of predators forces trees to rely on other forms of defense, like thorns.

How carnivores impact the African landscape

A new study shows the presence – or absence – of carnivores can have a big impact on how many and what kind of trees grow in a landscape. Working in central Kenya, researchers looked at different tree species – with or without protective thorns – in areas where herbivores get eaten by their predators, […]

Ebola in DRC different than that in West Africa

The current Ebola outbreak in the Democratic Republic of the Congo is caused by a different virus strain than the one circulating in West Africa, a new study shows. Researchers conclude that the two Ebola outbreaks are not linked to one another. At least 49 people have died from Ebola in Congo between July 26 […]

Exercise associated with fewer depressive symptoms

Regular exercise is associated with a reduction in the odds of depressive symptoms by up to 19 per cent, according to estimates in a new study. Researchers used data from the 1958 British Birth Cohort, which tracked about 11,000 people in the UK who were all born in the same week in 1958 through their lives. […]

Abundant natural gas won’t solve greenhouse emissions

Models suggest that a shift from coal to cheap natural gas is unlikely to lead to a significant reduction in greenhouse gas emissions worldwide. Natural gas is often touted as a greener fuel than coal because it produces fewer greenhouse gases, and due to advances in hydraulic fracturing technology it has become readily available. Researchers […]

By studying the electrical pulses emitted by this banded knifefish (Gymnotus carapo) scientists hope to gain insight into what’s going on in the brain when making voluntary decisions. (Photo credit: Tiago P. Carvalho)

Electric knifefish signal their intentions

Electric fields emitted by knifefish can be used to predict their movements a few seconds before they occur, making these creatures an ideal model organism to study voluntary decision-making. Electric knifefish are nocturnal and live in very murky water, so they feel their way by sensing distortions in an electric field that they emit using […]
