In a series of posts over at Scientific American's blog CrossCheck, John Horgan describes how several recent articles and books have prompted him to re-evaluate his views on nuclear energy. He specifically recommends Gynweth Craven's Power to Save the World, discusses John Mueller's Atomic Obsession, and describes how Wade Allison's Between Radiation and Reason has challenged his views about the risks of radiation exposure. Horgan's seminal End of Science partly inspired my research focus in gra........ Read more »

O'Leary and Gould (2010) tell us that in an area woefully short of research evidence, what they found in their study was that the adult male survivors of child sexual abuse can learn to cope well with that abuse history. Here, active, practical support from trusted others plays an essential role.... Read more »

Two of the most diverse groups of living things on Earth are flowering plants and the insects that make their living from flowering plants. Biologists have long thought that the almost incessant, intimate interactions between plants and plant-eating insects might be the evolutionary cause of each group's spectacular diversity. On a smaller scale, this means that we're interested in the reasons that specific insects and plants interact in the first place—what evolutionary trails leads one insec........ Read more »

What you can’t see can kill you. Researchers investigating why some birds are especially prone to hitting power lines have discovered that they literally can’t see where they are flying. That means typical anti-collision efforts, such as hanging warning markers on transmission lines, won’t help fowl that fly blind.

For patients with obesity and type 2 diabetes, bariatric surgery is by far the most effective treatment - it is, indeed, the only form of treatment that can put patients into full long-term remission.

“Adenovirus” (by Mapposity) There are two aspects about virology that constantly amaze me: How much we know about viruses, and how little we know about viruses.

In a series of posts, I’ve been discussing constraints on the evolution of colour terms. In the last post, I discussed Perceptual Warping. Here, a further adjustment to the assumptions about perceptual space is suggested.

In a recent paper, O. Moro Abadia and M.R. Gonzales Morales (2010) argue that an important component of the 'multiple species model' (MSM) that sees Neanderthals as having essentially 'modern' behavioral capacities and that originated in the late 90's is based not so much on new discoveries as it is on new ways of looking at the archaeological record. Specifically, they make the case that part of... Read more »

Photonics is all about light. Processing of light for applications ranging from holograms and displays to optical telecommunications. Thanks to a better theoretical understanding and to advances in fabrication technology, photonic devices and gadgets have become increasingly versatile and powerful.
But photonics also has a dark side. In many light-processing devices and structures there are dark modes — oscillations of the light wave that while not forbidden cannot be directly excited by a ........ Read more »
