Going Nuclear: Closing the Gap Between Radiation and Reason

by Matthew C. Nisbet in Age of Engagement

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 »

Coping Strategies for Men Sexually Abused as Children

by Ultimo167 in Strong Silent Types

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 »

Are mutualists monogamists, while antagonists play the field?

by Jeremy Yoder in Denim and Tweed

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 »

Flying Blind

by Journal Watch Online in Journal Watch Online

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.
The world’s 65 million kilometers of […] Read More »... Read more »

Will Surgery Cut Diabetes Costs?

by Arya M. Sharma in Dr. Sharma's Obesity Notes

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.
But is surgery really a cost-effective option for health systems looking to contain the immense economic and health burden of diabetes?
A paper [...]... Read more »

Fancy going on a wild plankton chase?

by Vivienne in Outdoor Science

Fancy going on a wild plankton chase around Antarctica this Christmas? In November 2002, a team of scientists did exactly that. They went on a nine-week expedition around the Southern Ocean – the ocean surrounding Antarctica – looking for a lush marine oasis awash with marine life and previously overlooked by science. Among their trials and tribulations, Dr Walter Geibert [...]... Read more »

Adenoviruses and the occupied sign

by iayork in Mystery Rays from Outer Space

“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. Adenovirus research offers examples of both. Adenoviruses are probably among the best-studied virus groups.1 We really do know an amazing amount about them. But it was only last year [...]...

Coiling bacterial DNA

by Grant Jacobs in Code for life

A chain of proteins hold bacterial DNA in a compacted spiral.

In earlier articles, I’ve mentioned in passing how the enormous length of DNA in our cells is fitted into [...]... Read more »

Evolution of Colour Terms: 8 Embodied Relationships

by Sean Roberts in A Replicated Typo 2.0

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.
The assumption that all perceptual spaces are the same may be unrealistic and may favour Universalism (see Levinson, 2000).  To begin with, . . . → Read More: Evolution of Colour Terms: 8 Embodied Relationships... Read more »

Synthetic ‘cradle’ boosts hope of stem cell therapies

Narcissism on Facebook

by Dr Shock in Dr Shock MD PhD

In normal every day life with face to face contact the physical characteristics and knowledge about social background form the identity of your contact. It’s stable and three dimensional. You know that person, it’s therefor very difficult for the other to claim another identity or create impressions inconsistent with how you know him or her. [...]

Portrait of the artist as a Neanderthal

by Julien Riel-Salvatore in A Very Remote Period Indeed

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 »

The dark side of photonics

by Joerg Heber in All That Matters

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 »

Rats Pee During the Night. A Surprise? Not Really

by Allison in Dormivigilia

Researchers have behaviorally confirmed an entrained rhythm of urination in the rat. Though this information is consistent with the recent shift in funding focus in circadian research (i.e. funding crutches), this is an example of a study that doesn't take advantage of advanced neuroscience techniques or at least attempts to elucidate the mechanisms. I mean, gosh, it was published in PLoS.... Read more »
