September 5, 2014

by Erin Campbell in HighMag Blog

It is so nice to have a friend who truly complements you…someone similar to you, but different enough to pick up the slack of your own shortcomings. Today’s image is from a paper about the Laverne and Shirley partnership of Ena/VASP and mDia2. Crawling cells extend finger-like filopodia to probe the environment for cues and to establish adhesion of the cell to the substrate. Filopodia are composed of parallel bundles of actin that are quickly dynamic. Countless actin regulators affec........ Read more »

Corals Engineer Their Own Currents

by Elizabeth Preston in Inkfish

There are few more monastic lives in the animal kingdom than a coral’s. In adulthood it gives up swimming to settle on the ocean floor, surround its spineless body with clones, and become a rock. Mouth facing the ocean, it waits passively for whatever drifts by—or maybe not so passively. Taking a closer look at […]The post Corals Engineer Their Own Currents appeared first on Inkfish....

People's belief in free will is lower when they need to urinate or desire sex

by BPS Research Digest in BPS Research Digest

Embodied or grounded cognition is the name for the idea that physical states affect our thoughts and emotions. It's a controversial field, but typical findings include people's judgments of social closeness being shaped by room temperature, and their attentional style by the clothes they wear. A new paper takes things further, asking whether bodily states affect people's philosophical beliefs, specifically their belief in the notion of free will, defined and measured here in the lay sense o........

Extremes of a self-limiting diet in autism

by Paul Whiteley in Questioning Answers

I'll draw your attention to three papers in today's post which represent the extremes of where self-imposed dietary restrictions can potentially lead in relation to the autism spectrum disorders (ASDs). Issues with diet - outside of use of diet as an intervention measure - are something which have been talked about quite a bit in the autism research literature (see here)."You look like a gangster"The first paper by Baird & Ravindranath [1] describes a case report of an 11-year old with ........

Brief Mindfulness Meditation Primer for Lawyers

by Dan DeFoe in Psycholawlogy

Can lawyers learn about its distinct components, and practice a process which involves interrelated components of attention regulation, body awareness, emotion regulation, and change in perspective on the self, and reach higher levels of self-compassion and well-being?  Stated another way, the question asks  “Can lawyers learn and practice mindfulness meditation?”  The short answer is [...]

Total Recall: How the Brain Processes Color and Motion

by Gabriel in Lunatic Laboratories

Despite the barrage of visual information the brain receives almost constantly, it retains a remarkable ability to focus on important and relevant items. This fall, for example, NFL quarterbacks will be rewarded handsomely for how well they can focus their attention on color and motion – being able to quickly judge the jersey colors of teammates and opponents and where they’re headed is a valuable skill. How the brain accomplishes this feat, however, has been poorly understood.... Read more »

Internet addresses are running out in Asia!

by Wiley Asia Blog in Wiley Asia Blog - Social Science

Internet addresses are "the numbers that uniquely identify computers and devices on the Internet". Although the current version of the Internet Protocol known as IPv4 provides 4.3 billion addresses, "they have already begun to run out". Computer experts created another Internet Protocol version in mid-1990s which is known as IPv6 that can provide "nearly infinite address space". The challenge, however, is that "IPv6 Internet is not backwards compatible with the........ Read more »

Drop the strut: Both men and women find humility more attractive

by BPS Research Digest in BPS Research Digest

By guest blogger Temma Ehrenfeld.There’s been much debate about the “cheerleader effect,” the idea that men are wired to attract desirable mates by showing off in silly ways. The effect may not even exist, but if it does, they might try humility instead. New research suggests that both men and women prefer humble to less humble partners.The studies are part of a push to define humility, a concept associated less with science than Christianity, as in Matthew 11:29 where Jesus says “I am........

Epigenetic processes and autism: focusing on immune function?

by Paul Whiteley in Questioning Answers

Although the title of this post talks about the science of epigenetics in autism, I'm actually going to be talking about two papers today, one of which also covers exposure to prenatal immune activation and what effect that might have on epigenetic processes in the mouse brain. This may also be relevant to at least some autism..."Beneath this mask there is an idea, Mr. Creedy. And ideas are bulletproof"First off we have the paper from Nardone and colleagues [1] (open-access) which, following som........ Read more »

Want people to care about the environment? Don't overplay the power of science

by BPS Research Digest in BPS Research Digest

When people are presented with a picture of rapid scientific progress, they are less likely to engage in environmentally friendly behaviours. This is the conclusion reached across a series of experiments in which students were presented with a short newspaper article on science's achievements and future prospects.The news article came in two flavours. Participants in the "progress" condition read a uniformly positive perspective, lauding medical advances and new technologies to combat climate ch........ Read more »

Encephalomyocarditis virus (EMCV) and autophagy: anti - and proviral effects

by thelonevirologist in Virology Tidbits

Encephalomyocarditis virus (EMCV) is small non-enveloped ssRNA with a genome of 7.8 kb and thus considerably smaller than CoV. Being the causative agent of myocarditis, encephalitis, reproductive disorders, diabetes, and neurological diseases, EMCV pathogenesis is viral strain and host specific. Although EMCV infection in humans are only associated with low morbidity, the use porcine xenografts may cause future problems. The expression of the EMCV 2C and 3D proteins has been shown to induce all ........ Read more »
