An oral pheromone makes male wasps unattractive to females

by Brooke LaFlamme in Molecular Love (and other facts of life)

Communication is essential to any successful relationship, and insect relationships are no different. And, as in human relationships, much of this communication is non-verbal. Chemical cues in the form of pheromones help females of many insect species decide when to mate who to make with and, when the deed is done, other chemicals let them know it’s time to stop dating and get serious about making some babies.

Joachim Ruther and colleagues at the University of Regensburg in Germany pub........ Read more »

Are The Mafia Psychopaths?

by Neuroskeptic in Neuroskeptic_Discover

The view that the Mafia is an organization of especially ruthless psychopaths is wrong – in fact, members of ‘Cosa Nostra’ have lower psychopathic traits than other criminals. That’s according to a new study from Italian researchers Schimmenti and colleagues, who, appropriately enough, are based in Sicily, the Mafia’s birthplace.

The Power of a Bedtime Story

by Katharine Blackwell in Contemplating Cognition

My 4-year-old nephew has an eclectic taste in bed-time stories. One week my sister will find herself reading the adventures of Spryo versus The Mega Monsters, the next week recounting the emotional journey of Mo Willem’s Knuffle Bunny, and the next reading captions out of Smithsonian’s Human: The Definitive Visual Guide. (Yes, at my nephew’s insistence). Unbeknownst to my sister, there may be a method to this seeming madness is pajama-clad reading choice; my nephew may be follo........ Read more »

New life for naltrexone and autism?

by Paul Whiteley in Questioning Answers

During the very earliest days of the life of this blog I posted about the opiate antagonist naltrexone (ReVia®) and some research on its history with autism in mind; in particular, the various emerging speculations on low dose naltrexone (LDN) (see here). Today I'm following up that entry based on the results of a systematic review by Ashok Roy and colleagues [1] on the value (or not) of naltrexone for "attenuating the core symptoms of autism spectrum conditions in children"."Yadwigha........

MERS-CoV and SARS-CoV: two members of a divergent family

by thelonevirologist in Virology Tidbits

Coronavirus infections are commonly associated with relative benign respiratory and enteric diseases in humans, such as the common cold, and with outbreaks among agricultural livestock -chickens, swine or cattle. The outbreak of a novel disease in humans, severe acute respiratory syndrome (SARS), in 2003 however highlighted the potential lethal consequences of Coronavirus (CoV) induced disease in the human population.

Nuclear envelope breakdown is far prettier than my own breakdown when I realized that Girl Scout “cookie season” is over. Today’s image is from a paper that describes the importance of SUN proteins in nuclear envelope breakdown.Early in mitosis, a cell’s nuclear envelope breaks down to allow the attachment of chromosomes to the mitotic spindle. Nuclear envelope breakdown (NEBD) depends on a tearing process, during which microtubules pull the nuclear envelope towards the centrosomes. T........ Read more »

Video Tip of the Week: EuPathDB

by Mary in OpenHelix

I love pathogens and parasites. Really, I do. I mean–not up very close. But their astonishing range and cleverness often earns my respect.

How About that Doggy at the Hair Salon?

by CAPB in Companion Animal Psychology Blog

Can we speed up the process of re-homing shelter dogs by getting the dog out of the shelter and into the community?Photo: AdamEdwards / ShutterstockEvery year, many dogs find new homes through animal rescues and shelters, but some have a long wait and many are never re-homed.  What if there was a way to free up shelter space and encourage people who would not visit the shelter to adopt? A new paper by Heather Mohan-Gibbons et al (2014) assesses the success of a scheme in which dogs were mov........ Read more »

It’s Not Just Chili Peppers That Are Hot

by Mark Lasbury in As Many Exceptions As Rules

The same receptor that senses capsaicin and regulates body temperature is also involved in osmoregulation. New studies indicate that a variant of TRPV1 in the magnocellular neurosecretory cells work in osmoregulation but do not bind capsaicin or sense heat. Another study has elucidated that TRPV1 acts only in hypertonicty; it senses cell shrinkage. Swelling due to hypotonicity is sensed by TRPV4. Together, these form a crucial part of the osmoregulatory system.... Read more »
