Sleepy Bees Waggle Sloppy

by Sharon Neufeldt in I Can Has Science?

For humans, sleep deprivation has a negative impact on performance in many areas, such as motor and communication skills.  In particular, communication impairment is the topic of an article published yesterday in . But the research in this paper isn’t … Continue reading →... Read more »

Plus and Minus of Teaching Obesity Genetics

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

One of the suggested ways to address weight-bias and discrimination amongst health professionals could be to teach medical students more about the genetic determinants of excess weight.
But will this really reduce weight bias?
This question was now addressed by Persky and Eccleston from the US National Institutes of Health in a study just published in the [...]... Read more »

The ‘artful dodge’: The danger of a smooth talker

by Rita Handrich in The Jury Room

In 1992, Sade sang ‘Smooth Operator’.  Almost two decades later we have research confirming that a smooth talker wins the day still. Put more bluntly—style trumps substance (particularly when that substance is delivered poorly). We say we want information, but really we want infotainment. Todd Rogers and Michael Norton (both at Harvard) showed participants different [...]

Nanotechnology endoscope for living cells

by Michael Berger in nanowerk

With the advance of nanomedicine, bio-nanotechnology, and molecular biology, researchers require tools that allow them to work on a single cell level. These tools are required to probe individual cells, monitor their processes, and control/alter their functions through nanosurgery procedures and injection of drugs, DNA etc. - all without damaging the cells, of course. Researchers have now developed a multifunctional endoscope-like device, using individual CNTs for prolonged intracellular probing........ Read more »

How male oil rig staff learned to lose their machismo

by BPS Research Digest in BPS Research Digest

Psychologists investigating two (non-BP) deep-water, offshore oil rigs in the Gulf of Mexico have applauded the working-practices they observed, claiming they allowed the predominantly male workforce to 'undo' gender - that is, to stop pursuing a counter-productive, masculine ideal.

Setting the scene in their new paper, Robin Ely and Debra Meyerson argue that dangerous work-places have traditionally encouraged male staff to 'do gender' by demonstrating physical prowess, taking risks, conc........ Read more »

Psycasm - The paper of Influence

by Rift in Psycasm

[Wherein our Hero looks at what research has most influenced him. A story to be continued...]As with most of these monthly themes, I'm at a loss. I'm still an undergrad, and am yet to be afforded the luxury of independent thought. I'm yet to commence honours, and further still from a PhD. I have a vague inkling of a preference towards a vast area of psychology, but what I would like; (read more)

We really do believe we’ve got more free will than the other guy.

by Scicurious in Neurotic Physiology

I tweeted this link all over the internets the other day, and not surprisingly, it got picked up a lot. And why not? Free will is one of those subjects that is particularly interesting to, well, just about everyone. It’s one the deep philosophical questions pondered by philosophers, and high people everywhere: DO we really [...]... Read more »

What kind of teachers do students want?

by Dr Shock in Dr Shock MD PhD

Students have different thinking styles. The way students think, perceive and remember information, or their preferred approach to using such information to solve problems can be different between students. Different models for learning styles are present. The mostly used is the learning style model by Kolb. Students have preferred learning styles as well as lecturers [...]

Tip of the Week: RepTar, a database of miRNA target sites

by Trey in OpenHelix

microRNAs have become a rich source of research as they probably have a huge effect on gene expression and disease. The human genome may encode over 1,000 miRNAs that target over half of our genes. They might be implicated in a lot of common diseases (which not yet have been picked up in GWAS studies?). They are a fascinating area of biology that has only come of it’s on in the last decade. As such, the number of databases to catalog miRNAs is large. Today’s tip is on a new one, RepT........ Read more »

Waldsterben all over again?

by Matthew DiLeo in The Scientist Gardener

Michelle tipped me off to yet another "all the bees are dying" article.

The new wrinkle in the story is a leaked EPA memo that suggests that Bayer CropScience's seed treatment, chlothianidin, was registered without sufficient proof that it didn't hurt bees. Aside from the fact that this registration was completed in 2004 and (according to the same article) this whole bee business started in the mid-1990s, I'm skeptical that any new pesticide is causing all this. We were SO much more indiscrimin........ Read more »

Looking to the Past in Search of New Drugs

by Dan Bailey in Smells Like Science

Scientists have often looked to nature in the quest for new drugs to treat everything from cancer to infectious diseases, and they’ve found effective drugs in unexpected places – sea sponges, the bark of the Pacific yew tree, a throat swab from a chicken. But archaeologist Patrick McGovern and an interdisciplinary group of researchers at the University of Pennsylvania are using a different approach: they’re looking to the past in search of new drugs....

Does conservation have an impact?

by TwoYaks in Gene Flow

For good or for ill, humans massively modify the world around them. From the perspective of other species, the majority of our modifications are "for ill." Some individuals realized that humans might irrevocably alter their favourite places, and thus was born the conservation movement out of local concerns. It wasn't until the 20th century that conservation of entire species really took off as a ... Read more »

The Time Travelling Brain

by Neuroskeptic in Neuroskeptic

What's the difference between walking down the street yesterday, and walking down the street tomorrow?It's nothing to do with the walking, or the street: that's the same. When seems to be something external to the what, how, and where of the situation. But this creates a problem for neuroscientists.We think we know how the fact that the brain could store the concept of "walking down the street" (or "walking" and "street"). Very roughly, simple sensory impressions are thought to get built up into........ Read more »
