Over fifty new potential drugs against Ebola

Researchers have identified 53 existing drugs that could prevent the entry of Ebola virus into human cells. To achieve this result, they screened 2816 drugs that are already approved by the Food and Drug Administration in the US. These drugs are already used as antibiotics, antihistamines (against allergies), antipsychotics or against cancer. They now need […]

What happens when lava meets snow?

Mixing lava with snow might seem to raise the risk of flooding for nearby settlements, but in fact it appears lava does not interact much with snow. Researchers in Eastern Russia, at the Tolbachik volcano, studied how snow and lava interact to determine the effects on lava advance and snow pack melting rates. Sheets of […]

Promising antibody found against dengue virus

An international team of scientists has discovered an antibody capable of neutralising all four forms of Dengue Virus (DENV). Dengue is a viral disease spread by mosquitoes. No vaccine or medication to protect against this emerging disease currently exist. Researchers hope this finding could lead to the development of a vaccine against the disease. The […]

The Darwin Awards, named after Charles Darwin, recognize individuals who have positively contributed to human evolution by accidentally removing themselves from the process of natural selection through their own actions. (Photo credit:  Julia Margaret Cameron, via Wikimedia Commons).

Battle of the brains: Men v. Women

A group of scientists have reviewed the data and the answer is in, men are more likely to be more idiotic than women. The authors reviewed 20 years of the Darwin Awards – which tell the ridiculous stories of how people accidentally kill themselves – and found that men made up 88.7 per cent of […]

The mystery of the old magazines in the waiting room

Physicians waiting rooms contain mainly old magazines and researchers have found that it was because current magazines have a greater risk of being stolen than older ones, a new study reports. Also, they observed that gossip magazines (with celebrity photographs on the cover) were more likely to disappear than other types (Time magazine and The […]

A new kind of stem cell

Scientists have observed a new class of stem cell with the capacity to turn into nearly any cell type. Called F-class cells for the fuzzy appearance of its colonies, these cells could potentially be used in regenerative medicine and drug discovery. In a second related paper, researchers with the Project Grandiose Consortium announce a new […]

Thousand tons of plastic floating in the oceans

At least 269,000 tons of plastic pollution could be floating in the world’s oceans, according to a new study. Researchers collected small, floating plastic particles across the Atlantic, Pacific and Indian Ocean as well as off the coast of Australia, in the Bay of Bengal, and the Mediterranean Sea between 2007 and 2013. They then […]

Unique woodpecker species where male travels more during winter migration

Female northern flickers, a woodpecker species who breeds during summer all across Canada, spends its winter farther north on average than males, according to a new study. Sex differences in migration distances are well known, but this is the first time researchers observed female birds that travel less distance than males. The authors believe this […]

Birds watch where they’re going

Flying birds rely on movements in the surrounding environment to control their position in space, a new study has found. The authors filmed hummingbirds hovering in front of a projection screen and examined the birds’ response to moving bars and spiral patterns compared to static images. The researchers found flying birds are sensitive to movements […]

No apparent correlation between HPV vaccine and risky sexual behaviour

Vaccinating teenage girls against the human papilloma virus (HPV) does not appear to increase risky sexual behaviour. There was concern that receiving the vaccination would cause an increase in such behaviour, however this study shows the concern is unfounded and should not prevent vaccinating girls at a young age. The study followed over 260,000 girls […]
