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 »

Pregnant and high: new treatments?

by PalMD in White Coat Underground

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........

Guest post - Microbes and Madness

by Lab Rat in Lab Rat

This guest post comes from my fiancé who is a Psychiatrist. I've been very excited about this post for a while, because unlike me, he is a published author who has written a book on Consciousness and the philosophy of mind.Microbes and MadnessAt first glance, it would be reasonable to assume that my profession and that of the author of this fabulous blog are poles apart. However, everything in nature has a connection, and so it is not surprising to discover a fascinating area where psychiatry a........ Read more »

Supply chain risk – it’s all in your head?

by Jan Husdal in husdal.com

Enhancing supply chain resilience with flexibility and redundancy is one way to counter supply chain disruptions. But do the chosen resilience measures actually play a moderating role in reducing the frequency of supply chain disruptions? This article paints an interesting picture of how supply chain professionals view risk, which risk they perceive and what they do in reaction to these risks.... Read more »

No Anomalous Enhancement of Nano-fluid Thermal Conductivity

by Arunn in nOnoScience (a.k.a. Unruled Notebook)

Nano was a buzz word a decade back in the USA. The buck was on anything prefixed with nano. Some useful technology did burgeon, identified now as nano-technology. Solar power, electronics and biotechnology were impacted with nano-engineered materials, capacitors and nano-probes and drug delivery methods. Chemistry and material science research in nano prospered with carbon [...]... Read more »

Kissing the mistletoe goodbye?

Kissing under the boughs of mistletoe is an oft-observed Christmas tradition, especially in the UK and the US. But, according to the UK’s National Trust, the years are fast approaching by when we may be kissing the UK mistletoe goodbye.The parasitic European Mistletoe, Viscum album, thrives on fruit trees such as the domestic apple tree and also other hosts such as lime, poplar, and hawthorn. Its heartland is the counties of Somerset, Gloucestershire, Herefordshire, and Worcestershire. How........ Read more »

New Mouse Model for Muscular Dystrophy

by Sanford- Burnham in Beaker

Roughly 50,000 people in the United States are affected by some type of muscular dystrophy, a condition characterized by debilitating muscle loss. Duchenne muscular dystrophy (DMD), the most common form of the disease, is caused by a mutation in the dystrophin gene. Without dystrophin, the interior muscle fiber frame can’t properly connect to the surrounding [...]... Read more »

The neuroscientific study of hallucinogens

Recently, an important and landmark paper was published in PLoS ONE (hooray open access!) titled, "Investigating the Mechanisms of Hallucinogen-Induced Visions Using 3,4-Methylenedioxyamphetamine (MDA): A Randomized Controlled Trial in Humans". It sounds daunting, but trust me, it's a very cool, approachable study.Now, in the spirit of full-disclosure, the lead author Dr. Matthew Baggott (hereafter referred to as "Matt"), is a friend of mine from grad school and he's been kind enough to grant me........

The snowshoe hare-coyote-Dall's sheep cycle?

by TwoYaks in Gene Flow

When we teach our students predator-prey relationships, we tend to tell them a very basic story that have come from a few very good studies. It's not that all we have are simple models, but but we like to build up the basics before we dive into the complexities. Because when you get down to the complexities, a lot of counter-intuitive things happen which don't follow "common-sense" relationships.... Read more »
