Four Solar-Powered Animals
Photosynthesis, a process used by plants and some bacteria to convert light from the sun into chemical energy which can be later released to fuel their activities. Animals on the other hand, have to consume other organisms in order to cover their energy needs. But every rule has an exception.In recent years, researchers have discovered a small number of animals that much like plants have found a way to directly harness and feed off the Sun’s energy.1# Oriental Hornet (Vespa […]

How reminders of money affect people's expression and perception of emotion
Bank robbers and gamblers will tell you what people are prepared to do for the sake of money. But money also has more subtle influences. Back in 2006, researchers showed that mere reminders of money made people more selfish (although note a later attempt failed to replicate this result).In the latest research in this field, a team led by Yuwei Jiang have shown that exposing people to pictures of money, or to money-related words, reduces their emotional expressivity and makes them more sensitive […]

Postpartum depression and the broader autism phenotype?
"The findings suggest that pregnant women with BAP [broader autism phenotype] have an elevated risk for PPD [postpartum depression]".That was the conclusion reached by Ryosuke Asano and colleagues [1] based on their analysis of data derived from the Hamamatsu Birth Cohort (HBC) Study [2]. The idea being that the more subtle presentation of issues linked to a diagnosis of autism spectrum disorder (the BAP) might predispose to a great likelihood of other behavioural or […]

Microscopic observation in live tissue, awesome! But don’t ignore the methods
It has been far too long since I wrote a blog post. Look out internet, I have a blogging itch that needs scratching, and it’ll probably cause a rash! …I apologize for that mental image. The NIH sent me an email this week (via the various government listservs I’m enrolled in) that was proudly declaring […]

Are All Labrador Retrievers the Same?
Or do show dogs and field dogs vary in temperament?Photo: c.byatt-norman / ShutterstockIt’s often said there are personality differences between Labrador Retrievers bred to show (conformation dogs) and those bred to work (field dogs). And chocolate labs have a reputation for being different than black and yellow labs. Is it true? New research by Sarah Lofgren et al (Royal (Dick) Veterinary School, University of Edinburgh) investigates.Although many Labrador Retrievers are family pets, […]

Video Tip of the Week: SeqMonk
Always on the lookout for effective visualization tools, I recently came across a series of videos about the SeqMonk software. It’s not software that I had used before, so I wanted to look at the videos, and then try it out. It downloaded quickly, offered me an extensive list of genomes to load up, and […]

Death By Haunted House
Halloween is a time when fear is invited. The rush of adrenaline in a controlled environment is life-affirming. Not much else to comment on here, except that he seems to have excellent oral hygiene for a chainsaw-wielding maniac.A big man with the chainsaw and the gaping wound on his face jumps out from around the corner and growls. You leap backward and scream, your heart pounding in your ears. You’re ready to either take that power tool and teach him a lesson or to run like the kid from […]
