Simple Jury Persuasion: Tilt your head. (no kidding)

by Rita Handrich in The Jury Room

Evolutionary psychologists do some weird research. But we’re not holding that against them.  I mean, we’re talking about evolution.  Instead, we’ll take what they find and translate it for your use at trial. But this is odd! Australian researchers (Burke & Sulikowski, 2010) looked at tilting heads and attractiveness in the eyes of observers. What [...]

Sedentary Physiology Part 5 – Future Directions

by Travis Saunders, MSc, CEP in Obesity Panacea

Image by kaibara87
Welcome to our 5-part series delving into the fascinating research being performed in the emerging field of sedentary physiology.  In Part 1 we discussed the basics of sedentary physiology, in Part 2 and Part 3 we looked at the association of sedentary time with both death and disease, and in Part 4 we looked at the mechanisms underlying these relationships.  Today we will look at where future work in the field of sedentary physiology is heading.
Given the research that we........ Read more »

Painting the human tree of life

by Razib Khan in Gene Expression

Tishkoff et al.
Reading Peter Bellwood’s First Farmers: The Origins of Agricultural Societies, I’m struck by how much of a difference five years has made. When Bellwood was writing the ‘orthodoxy’ of the nature of the expansion of farming into Europe leaned toward cultural diffusion. Today the paradigm is in flux, as a new generation of [...]...

Meditation vs. Medication for Depression

by Neuroskeptic in Neuroskeptic

What's the best way to overcome depression? Antidepressant drugs, or Buddhist meditation?A new trial has examined this question: Segal et al. The short answer is that 8 weeks of mindfulness mediation training was just as good as prolonged antidepressant treatment over 18 months. But like all clinical trials, there are some catches.Right mindfulness, sammā-sati, is the 7th step on the Buddha's Nobel Eightfold Path of enlightenment. In its modern therapeutic form, however, it's a secular practi........ Read more »

Another nanotechnology step towards 'Fantastic Voyage'

by Michael Berger in nanowerk

Off-targeting remains a key challenge of researchers working on nanoparticle drug delivery - the majority of intravenously administered therapeutic nanoparticles are also reaching normal tissues, resulting in considerable adverse side effects. Another challenge of nanoparticle drug delivery includes the limited penetration depth of particles into the tumors. While extensive efforts have been devoted for designing therapeutic nanoparticles, a new study - echoing the journey through the human body........ Read more »

Could a new photoreceptor in fly larvae give us a glimpse at the evolutionary origins of vision?

by Michael Bok in Arthropoda

Last month, a paper was published in Nature showing that fruit fly larvae (Drosophila melanogaster) have a photoreceptive system spread across their entire bodies in diffuse sensory neurons. This system is involved in escape responses that protect the larvae from exposure to high intensity light. (For a thorough explanation of this paper read this post [...]... Read more »

Biomimicry: Borrow From Nature! Mother Earth Forgets To Patent

by DJ Busby in Astronasty

Lately I've noticed a decent amount of technological innovation resulting from biomimicry. Aeronautics traditionally seems to reap the most benefit from this process, but that field is by no means the only one benefiting. We often come up with designs inspired by nature, but how often is our end result superior than our inspiration?... Read more »

Solar Powered Hornets?

by Dan Bailey in Smells Like Science

The phrase “solar powered hornets” may conjure terrifying images of a futuristic, stinging swarm of eco-conscious, half-insect, half-machine hornets. But these hornets might already exist. And don’t worry, they’re just normal hornets. Researchers have recently discovered that the Oriental hornet may be capable of harvesting energy from sunlight.... Read more »

Many years ago a woman came to OB triage at my hospital.  She was about 28 weeks pregnant and feeling horrible.   As the nurses hooked her up to monitors and started an IV, she clutched a pink, kidney-shaped emesis basin, her boyfriend holding her hair back and away.  A few minutes later, she called [...]...

Fish Have Feelings (And They Can Be Seen In Their DNA)

by Christie Wilcox in Observations of a Nerd

Most animals reproduce sexually. This means that every individual has to find another individual to mate with - and they have to convince that other that they're worthy of the privilege. More often than not when it comes to picking that special someone, it's the girls that get to be choosy. Females spend a lot more energy per offspring than males from the get-go due to the size of our eggs (let alone most child rearing responsibilities), so as a gender, females want to make sure they don't waste........
