10:29 AM | Subduction is not the end
Subduction is just the beginning. Stuck on the surface of the earth as we are, it’s easy to think that when oceanic lithosphere is destroyed when it vanishes into the mantle. But this is wrong. The more we manage to peer … Continue reading →

Sleep is a hot topic lately, are we getting too much, too little, how much is enough? However, most of these questions are for adults, so what about children? Well […]

3:59 PM | Are we really evolving into super-humans?
© EEGI came across an article on the Popular Science website, which, turns out, is the excerpt of a new book on evolution by Science Guy Bill Nye. From the reviews I gather that Bill Nye is an excellent writer and, being also an entertainer, he knows how to not only expose well but also infuse some good humor to what he says. That's all fantastic. But while the article starts off with some rigor, his conclusion had me roll my eyes. Because, even though he does include some […]

9:51 AM | UK Millennium Cohort Study: School and the disabled child
Quite recently the BBC News online ran with the headline: "Disabled children's behaviour 'deteriorates at school'". The story revolved around the findings reported by Rebecca Fauth and colleagues [1] (open-access) looking at "the extent to which the associations between disability and behaviour are linked to children’s developmental stage and thus may be ‘grown out of’ as children enter school and move out of the early years". I should add that, at the time of writing, the […]

3:37 PM | Breaking Research: A method by which invading bacteria avoid detection could also be our key to defeating them
Have you ever wondered how our body recognizes when it’s being invaded by harmful bacteria? Nearly all forms of life—from single-celled organisms all the way to humans—have an “innate” immune system, which has evolved to recognize cellular components shared by broad groups of pathogens. One such example is peptidoglycan, a molecule found on the cell […]

10:00 AM | Countries with more gender equality score more Olympic medals - among women and men
There are huge benefits to be gained when women and men are given equal opportunities. For example, companies with at least one woman on their board are more successful. In countries with less stereotyped views about women's abilities, girls tend to perform better at science. Now a team led by Jennifer Berdahl has extended this line of research to the realm of sport. In countries with greater gender equality, they find, both women and men tend to perform better at the Olympics.The researchers […]
