3:46 AM | Unpacking Recovery Part 4: Are We All on the Same Page?
Another issue in defining and understanding recovery is that patients and clinicians may have different opinions about what recovery looks like and how to get there. Certainly, there is a body of literature from the critical feminist tradition in particular that explores how at times, patients can “follow the rules” of treatment systems to achieve a semblance of “recovery,” from a weight restoration and nutrition stabilization perspective, but feels nothing like a full […]

3:15 AM | Falsifiability and Gandy’s variant of the Church-Turing thesis
In 1936, two years after Karl Popper published the first German version of The Logic of Scientific Discovery and introduced falsifiability; Alonzo Church, Alan Turing, and Emil Post each published independent papers on the Entscheidungsproblem and introducing the lambda calculus, Turing machines, and Post-Turing machines as mathematical models of computation. The years after saw many […]

7:09 PM | The hope behind climate change: adaptation strategies for coastal regions
Happy Labor Day!  In honor of a day traditionally taken off (except for retail employees, unfortunately) to enjoy grilling and relaxing outside, I thought I’d discuss something a bit more upbeat.  Climate change research can often be gloomy.  It is … Continue reading →

11:56 AM | New Clues Revealed about the Longevity of Naked Mole Rats
Naked Mole RatCredit: UT Health Science Center at San AntonioThe hairless, odd-looking creature in the photo is a naked mole rat (Heterocephalus glaber).Among many weird traits, the species also holds the record for longest living rodent. For comparison, the house mouse (Mus musculus) has a maximum lifespan of just 2-3 years, whereas naked mole rats have been recorded to live as much as 32 years!The exact mechanisms behind the species remarkable longevity have yet to be clearly unveiled, […]

8:34 AM | Students with more autistic traits make fewer altruistic choices
Most people with autism have difficulties socialising and connecting with others. It's generally agreed that part of this has to do with an impairment in taking other people's perspective. More specifically, an emerging consensus suggests that autism is associated with having normal feelings for other people, but an impaired understanding of them. Little explored before now is how this affects the behaviour of people with autism towards others who need help.Leila Jameel and her colleagues […]

Are men who inject testosterone and other anabolic steroids at risk of entering a violent “roid rage“? Many people think so.

Parkinson’s disease is caused by the progressive death of neurons important for movement and results in symptoms such as shaking or rigidity in the limbs, slow movements, and difficulty walking. The primary treatment is a drug called L-Dopa, which compensates for the neuron loss but eventually becomes less effective as more and more neurons die […]

10:38 AM | Fish with Lungs Gives Clues to the Origin of Tetrapods
Juvenile Polypterus senegalusAbout 400 million years ago, fish left the water and began to evolve into land-living creatures. But how did this transition happen? In a new and unusual study, researchers from the McGill University took a fish species known to be able to occasionally walk using its fins and raised it on land. The scientists found that when raised on land, this primitive strange fish with lungs, walks much better than its water-raised friends. The experiment could […]
