Aww, crap.

by Grant Jacobs in Code for life

D’em shrews have shat in me again.
Botanist Dr. Charles Clarke (Monash University, based at Monash’s Selangor campus) has published two research papers showing that the pitchers of mature pitcher plant Nepenthes lowii are opportunistic toilets rather than predatory traps.
Carnivorous pitcher plants typically have waxy interiors and other devices in their pitchers and narrow entrances to [...]... Read more »

Pandemic norovirus rapidly evolves to make you vomit

by geekheartsscience in geek!

Pandemic noroviruses have a faster rate of evolution than non-pandemic strains, which could explain why they are better adapted to cause worldwide outbreaks of viral gastroenteritis, according to research published free in PLoS Pathogens this week.

Norovirus is an RNA virus that is responsible for the majority of viral gastroenteritis outbreaks worldwide. Norovirus infection—dubbed ‘winter vomiting [...]... Read more »

Is the Man Flu a Reality?

by Christie Wilcox in Observations of a Nerd

We all get sick. Young or old, male or female, everyone gets sick at some point in their lives. But only some are susceptible to a specialized disease known as the "Man Flu," which somehow causes men to think they have the flu when, in fact, they have only a little cold.

Where did the idea of a Man Flu come from? It's origins are uncertain. In general, a lot of people tend to think they're worse off than they really are when they're sick - a poll by Panadol Cold and Flu, for example, found tha........ Read more »

The sex chromosomes: keys to the evolution of human intelligence?

by Isabelle Winder in Going Ape

Recent surveys of educational attainment and schooling suggest that girls are outperforming boys all the way through from primary school to A-levels. The reason for this discrepancy, though, remains unknown. Many explanations have been suggested, ranging from the fact that there are simply more boys who fall into the category of disadvantaged" to boys lacking interest, having shorter attention spans, or not being encouraged to take learning seriously by male role-models.But could there be a simp........

Dormant viruses can hide in our DNA and be passed from parent to child

by Ed Yong in Not Exactly Rocket Science

During our early childhoods, the vast majority of us are boarded by a stowaway that can stay with us for the rest of our lives. It can rear its head when we are at our weakest and it can wriggle its way down our family tree into our children and grandchildren. It’s a virus called [...]... Read more »

Ménage à trois – the good, the bad and the ugly

a new, smarter weapon against cancer cells?

by Greg Fish in weird things

They sneak in, find and neutralize their target with a complex biological weapon, then sneak out before they’re even detected. No, they’re not a special forces squad from a spy novel. They’re actually 70 nanometer particles which could become one of the most important weapons in fighting cancers if their promise is proven in large [...]... Read more »

Character strengths and virtues: a 5/8 factor structure?

by sandygautam in The Mouse Trap

Positive psychology is based on the premise that it is equally important to study what is good in life as it is to study what goes wrong. Positive psychology thus focuses on building and capitalizing on existing strengths of people while not focusing too much on their weaknesses, which has been focus More >Rating: 0.0/10 (0 votes cast)

How Shoes Can Change Your Life - And Your Skeleton

by Isabelle Winder in Going Ape

A cross-section of a foot inside a shoe. Taken by Mattes, and downloaded from the Wikimedia Commons 26/03/2010.You might think that shoes can only change your life if you are a sex-and-the-city type shoe lover, spending huge amounts of money on designer footwear. And for most of us, that kind of dedication to shoes is fairly incomprehensible - after all, they're just things to wear to keep your feet safe from broken glass and tarmac, right? Wrong....In fact, footwear doesn't just change your lif........ Read more »

UPDATE : Bi-Directional Optogenetic Control

by AndrewHires in Brain Windows

The Deissseroth lab has released an updated version of their optical neuronal silencing gene Natronomonas halorhodopsin. In Molecular and Cellular Approaches for Diversifying and Extending Optogenetics, Gradinaru et al review current optogenetic methodology, and introduce eNpHR3.0-2A-ChR2, a genetic vector whose expression allows both action potential silencing and firing via illumination. This vector uses post-translational cleavage (via cis-acting hydrolase elements) [...]... Read more »

Self-destruction of the mirror neuron theory of action understanding

by Greg Hickok in Talking Brains

Rizzolatti & Sinigaglia's new Nature Reviews Neuroscience paper on the mirror system is effectively an admission that the mirror neuron theory of action understanding is wrong. The original is idea was interesting: we understand actions by mirroring those actions in our own motor system. But this is no longer the case according to R&S:By matching individual movements, mirror processing provides a representation of body part movement that might serve various functions (for example, imitation), b........
