Insights into protein structure could change the future of biomedicine

by Dr. Jekyll in Lunatic Laboratories

Researchers at the University of Waterloo have discovered a new way to create designer proteins that have the potential to transform biotechnology and personalized medicines.

In a range of experiments Professor Elizabeth Meiering, in collaboration with colleagues from India and the United States, created a protein that can withstand a range of physiological and environmental conditions – a problem that has challenged chemists looking to create super stable, highly functional proteins....

The blue dye that helped turn a woman green

by Rosin Cerate in Rosin Cerate

When a person is unable to eat, a tube may be inserted down their throat in order to get nutrient-rich goop into their stomach. Dyes are often added to the goop to help healthcare workers ensure it doesn't accidentally end up in a patient's lungs. This situation, otherwise known as pulmonary aspiration, can lead to pneumonia or, worst case, death by asphyxiation.In one rather remarkable case, a woman being treated for multiple organ failure acquired an intense green skin colour while being tube ........

How Spider Personalities Affect Pest Control

by Elizabeth Preston in Inkfish

They say you can catch more flies with honey than with vinegar. But what about with lazy spiders versus lively ones? When it comes to keeping pests at bay, the personalities of the spiders hunting them are important.

That's what two behavioral ecologists reported after watching bug dramas play out in a sunny hilltop alfalfa patch. Raphaël Royauté of North Dakota State University and Jonathan Pruitt of the University of Pittsburgh were studying the personalities of wolf spiders (Pardosa mi........ Read more »

Why do people find some nonsense words like "finglam" funnier than others like "sersice"

by BPS Research Digest in BPS Research Digest

Calm down, it's not that funny! When you're trying to understand a complex phenomenon, a sensible approach is to pare things back as far as possible. For a new study, published recently in the Journal of Memory and Language, psychologists have applied that very principle to test a popular theory of humour.The theory states that, fundamentally, we are most often amused when we are surprised by, and then resolve, an apparent incongruity: a word that didn't mean what we originally thought........

Corn Color Concepts

by Mark Lasbury in As Many Exceptions As Rules

Indian corn isn’t corn, it’s maize. But not all corn is maize, corn is actually an old word that denotes the major crop of any particular region. The colors are most beautiful, including a newly breed variety called Carl’s Glass Gem corn. The spots of color were instrumental in our understanding of DNA and gene movement, but do you think we would be so fast to decorate our houses with it if it were common knowledge how much Indian corn has in common with the causative agents of........

Pinocchio and Captain Hook: Suffering from Tinnitus?

by Chiara Civardi in United Academics

You might be wondering what Pinocchio and Captain Hook have in common. Well, they are both from children’s stories, they both have prosthetics, they have issues with being honest, and they both experience interesting maritime adventures. But there is something else too: they are both annoyed by a continuous ticking sound that follows them everywhere. For Pinocchio it is Jiminy Cricket who bothers him while for Hook the crocodile is ticking merrily away. I can hear you saying: “So? Wh........ Read more »

Embrace your bad moods and they may not take such a toll on you

by BPS Research Digest in BPS Research Digest

"Being upset is a warmer, close-up feeling, not a chilly distant feeling like laughing at people" from Margaret Atwood's The Heart Goes LastGenerally speaking, being in a bad mood isn't just no fun, it also isn't good for you – people who feel negative emotions like anger, anxiety and sadness a lot of the time tend to have poorer social lives and suffer worse physical health in the long run, suggesting that dark moods take a toll. But a new study published in Emotion shows how this i........ Read more »

Afflictions of early automobile users

by Rosin Cerate in Rosin Cerate

The widespread introduction of the automobile in the early 20th century brought with it an unfortunate collection of new ways to get injured. In addition to collisions, people were harmed by hand cranks, detachable rims, and carbon monoxide.Back in the day, motor vehicles had to be started by hand. Within a car's engine, the up-and-down motion of pistons (produced by igniting a fuel-air mixture) is converted into rotational motion via a crankshaft. When starting up an engine, the crankshaft has ........ Read more »

Guilt-proneness and the ability to recognize the emotions of  others

by Doug Keene in The Jury Room

Three years ago we wrote about the goodness of fit for the guilt-prone with the presiding juror position. Counter-intuitive as it may seem, there were a number of reasons supporting them in that role. And today, new research gives us another reason the guilt-prone may be more skilled at leadership—they are more able to identify […]

On some issues, liberals are more dogmatic than conservatives

by BPS Research Digest in BPS Research Digest

In the liberal worldview, conservatives are notoriously narrow-minded – and for years we’ve had the science to prove it. Meta-analyses published in 2003 and 2010 of dozens of studies using different measures revealed a consensus on "the rigidity of the right" – that is, people who hold more right-wing views tend to be more close-minded. Case closed? Or should we be open to other perspectives, such as the one offered in a new article published recently in Political Psychology. Produced by a........ Read more »
