New data on SmartFlare – do they detect mRNA?

by Gal Haimovich in Green Fluorescent Blog

Almost exactly a year ago, I wrote a post regarding my concerns with SmartFlare, supposedly a novel method for live imaging of RNA in cells. In a nutshell, SmartFlare are gold nanoparticles covered in oligos specific to a certain mRNA … Continue reading →... Read more »

Early wrong ideas about how our glands work

by Rosin Cerate in Rosin Cerate

Let's talk about glands! These highly specialized bits of tissue put together and pump out useful compounds to ensure we stay healthy and can do the things animals do (aim to reproduce, mostly). Exocrine glands release fluids such as sweat, saliva, milk, tears, mucous, and bile into segments of our digestive tract or onto the surface of our skin (and eyes). Endocrine glands toss hormones and other regulatory molecules into our bloodstream, to be carried to distant locales bearing instructions to........ Read more »

Education about Cats may Reduce Feline Behaviour Problems

by CAPB in Companion Animal Psychology Blog

Behavioural advice for people with a new kitten is linked to a better-behaved pet at 1 year old.A new pet can be hard work, and if people don’t fully understand the needs of their animals, behaviour problems can result. A new study investigates whether education for owners at their first vet appointment is the answer. People with a new kitten (3 months old) were given 25 minutes of standardized advice on caring for cats. The study, by Angelo Gazzano et al (University of Pisa) compared the........ Read more »

Give Thanks For The Cranberry

by Mark Lasbury in As Many Exceptions As Rules

Here comes Thanksgiving! The cranberry is an amazing fruit on its own for several reasons. Its cultivation and botany are unusual, as is its seed dispersal mechanism and structure. However, a major push has been on to understand the medicinal uses of the cranberry. Much debate is taking place as to the usefulness of cranberry compounds, anthocyanidins and polyphenols, in the prevention of urinary tract infections. Cranberry is even having some success in type II diabetes and as an anti-viral age........ Read more »

The Motivation to Express Prejudice Scale 

by Doug Keene in The Jury Room

We hear a lot more these days about covert or “modern prejudice” than we do about plain old overt prejudice. So it’s a little surprising to see this measure but it makes sense. There are some people who do want to express prejudice and here is a scale you can use to measure their wishes […]

What happens when you fall in love with someone who's aggressive?

by BPS Research Digest in BPS Research Digest

Does experiencing aggression in a relationship make us more vigilant against it – or more forgiving? New research published recently in the Journal of Personality and Social Psychology suggests that when we want to keep our partner badly enough, we redefine the levels of aggression that we believe it is justifiable to endure.Aggression can manifest in obvious violations such as controlling behaviours or physical violence, but also includes more common behaviours – denigrating a partner, or t........

The kynurenine pathway and some autism

by Paul Whiteley in Questioning Answers

"Our data indicated that there were alterations to the KP [kynurenine pathway] in ASD [autism spectrum disorder]. Specifically, increased production of the downstream metabolite, quinolinic acid, which is capable of enhancing glutamatergic neurotransmission was noted."Those were some of the rather interesting results reported by Chai Lim and colleagues [1] suggesting that when it comes to tryptophan metabolism in relation to autism, the continued sole focus on serotonin and melato........

Sports psychologists understand surprisingly little about "the yips"

by BPS Research Digest in BPS Research Digest

Two-time Masters Champion Bernhard Langerhas battled the yips throughout his career. He told the Telegraph they are: "an involuntary and uncontrollable movement of the muscles, resulting in a fast, jerky, uncontrolled putting stroke. It is like a muscle spasm; you hold the putter this way or that way - it doesn't matter - and sometimes you can't take it back. You freeze, you totally freeze - or you just jerk."Image: Wikipedia. A golf champion prepares for the easiest of putts on t........ Read more »

Sex, STEM careers and the 'big data' of the Autism-Spectrum Quotient (AQ)

by Paul Whiteley in Questioning Answers

I'm a fan of 'big data' on this blog (see here) and the particular idea that large participant numbers can offer up some really important results or patterns of results relevant to our knowledge of labels like autism.  I do also believe there is a balance to be struck between big data and somewhat smaller data - specifically the value of the N=1 when it comes to a heterogeneous condition like autism - but big data is a nice way of introducing or confirming more general trends and/or correla........

Being true to yourself may protect against the harmful effects of loneliness

by BPS Research Digest in BPS Research Digest

A lot has been written about the downward spiral of loneliness. People who crave more social contact often develop behaviours and thinking styles that only serve to accentuate their isolation, such as turning to drink and becoming more sensitive to perceived slights and rejections. Less studied is the question of whether some people have personality traits that give them a buffer against these loneliness-related risks. A new study published in the Journal of Health Psychology finds a promising c........ Read more »

Freak bacterial skin infections in hockey players

by Rosin Cerate in Rosin Cerate

I suspect I'd be dead if not for antibacterial drugs (most people call them antibiotics, but I'm stubborn and prefer a more specific term). As a preschooler, I spent several months being very ill with tonsillitis. It took more than a couple rounds of bacteria-harming drugs to fix me up, and who knows if I would've been able to kick the infection without them before my throat closed up or my heart failed due to rheumatic fever. Due at least in part to my childhood experience, I'm morbidly fascina........ Read more »

Careful – a long-running rivalry can make you reckless

by BPS Research Digest in BPS Research Digest

Victory is always gratifying and acquires an even more delicious taste when it involves the defeat of a rival. But new evidence published recently in the Journal of Personality and Social Psychology suggests that rivalries, as well as spurring us on, also promote a mindset that favours eagerness, even recklessness – a mindset that seeks to achieve a legacy for the history books, but carries a risk to our chances on the day.NYU psychologist Gavin Kilduff defines rivalry as a relationship charac........

The Neuroscience of Social Media: An Unofficial History

by The Neurocritic in The Neurocritic

There's a new article in Trends in Cognitive Sciences about how neuroscientists can incorporate social media into their research on the neural correlates of social cognition (Meshi et al., 2015). The authors outlined the sorts of social behaviors that can be studied via participants' use of Twitter, Facebook, Instagram, etc.: (1) broadcasting information; (2) receiving feedback; (3) observing others' broadcasts; (4) providing feedback; (5) comparing self to others.Meshi, Tamir, and Heekeren / Tr........
