5:03 PM | Emperors in danger: penguin populations predicted to decline due to climate change and sea ice loss
If pop culture is any indication, we hold a special place in our heart for penguins compared to the many other denizens of the animal kingdom. Maybe it is something about the close-knit familial communities that have been portrayed in documentaries … Continue reading →

3:07 PM | New Species of Spider Wasp Uses Ant Corpses to Protect Its Nests
A newly discovered wasp species uses the corpses of dead ants as scarecrows, to protect its nest from predators, according to a new study by researchers at the University of Freiburg. Scientifically described as Deuteragenia ossarium and dubbed as the Bone-house wasp, the species uses the chemical cues from ant corpses to ward off predators, by stuffing them into the crevices of its home. The species was discovered in Jiangxi Province in south east China.Wasps use a wide range of […]

Though using dikes to protect the world from rising sea levels will generally make economic sense, explains Jochen Hinkel from the Global Climate Forum, poor countries may not have the resources to do so.

3:46 PM | Chimps stick grass in their ears to be cool: notes on cultural transmission
1. In 2010, a female chimpanzee named Julie began repeatedly stuffing a stiff blade of grass into her ear.

In three other groups of chimpanzees found in other locations in […]

12:00 PM | How Do Mosquitoes Find You?
Biology concepts – semiochemicals, hematophagy, proboscis, thermosensing, TRPA1Sure, mosquitoes suck blood and pass along malaria that kill more humans than any other infectious disease. But would it be good to get rid of them. They provide food for birds – one scientist suggests that elimination of Arctic mosquitoes could reduce northern bird populations by 50%. And mosquitoes pollinate flowers too, like blueberries and cranberries. See, they’re not all bad.We can start our […]

11:51 AM | What happens to the cool kids when they grow up?
"Cool kids", according to a new study, are those early teens (aged 13 to 15) who want to be popular, and try to impress their peers by acting older than their years. They have precocious romantic relationships, commit relatively minor acts of bad behaviour (such as sneaking into the cinema without paying), and surround themselves with good-looking friends. These teenagers attract respect from their peers at first, but what's the story by the time they reach early adulthood?Joseph Allen and his […]

7:40 AM | Quality of life and autism
The BBC ran an interesting article on their website recently titled: Happiness and disability. Discussions about the disability paradox - whereby some people with often significant and persistent disability report experiencing a good or excellent quality of life (QoL) - got me thinking about QoL and in particular, how it might relate to the very wide and very heterogeneous autism spectrum. I might add that I am not insinuating that everyone diagnosed on the autism spectrum are 'disabled' but […]
