Flower engineers

by Africa Gomez in BugBlog

Yesterday I was following a queen Bombus terrestris, as usual, with the faint hope one will nest in my garden when she landed on a comfrey patch. This was the first time I have seen this species on comfrey, their deep flowers are mostly visited by Bombus pascuorum, B. hypnorum and B. pratorum*, in addition to Anthophora plumipes. The heavy queen landed on top of the flowers, and I was able to approach without disturbing her. She noisily bit the top of a flower and then inserted her ton........ Read more »

Challenging the Plasticity Limits of Visual Development

by William Yates, M.D. in Brain Posts

Pawan Sinha is an MIT academic engineer who is involved in a combined humanitarian, medical and scientific effort to understand childhood blindness. He has established a program in India called Project Prakash to identify children with congenital cataracts who would benefit for early correction. Early correction is key to prevent persistent blindess as visual plasticity declines over time if the retina and brain are not stimulated. He has challenged the idea that vision cannot be established ........ Read more »

Exercise and Back Pain – Hell’s own elephant

by Lorimer Moseley in BodyInMind


It’s getting cramped in here and I can’t work out why. I’m inside a room labelled ‘how to treat low back pain’ and something enormous is taking up all the space.
Exercise is at the heart of the physical therapies in the treatment of back pain. Most forms of therapeutic exercise boast arguably plausible theories and [...]... Read more »

Who's to blame for the financial crisis

by Tom Rees in Epiphenom

Astute observers will have noticed that there's been something of a crisis in the financial world over the past couple of years. The EU's just coughed up €500 billion in the latest an effort to stem the panic... or, alternatively, to fend off the predators.

And that gets to the heart of the matter. Is the crisis just one of those things - part of a natural economic cycle that is beyond anyone's ability to predict or control? Or is it a result of moral or intellectual failures among those who........ Read more »

Carbon Dioxide and Lifespan in Drosophila

by Colby in nutsci.org

My first post to this blog began with a fascinating study by Scott Pletcher that found odor from yeast can accelerate the ageing of dietary restricted Drosophila.  His group recently published another study that adds to our understanding (1), which I summarize below.
The investigators chose carbon dioxide (CO2) to study because of its known role [...]... Read more »

Viral Turtles

by Merry Youle in Small Things Considered

A double stranded RNA (dsRNA) viral genome, introduced into a host cell, is met by formidable host defenses. The very presence of dsRNA in a eukaryotic or prokaryotic cell announces a viral infection and elicits effective responses, ranging from silencing of the viral mRNAs to apoptosis. Despite that, there are successful dsRNA viruses throughout the biosphere. By...... Read more »

Comparing Ghrelin Levels Across 2 Bariatric Surgical Techniques

by Maureen McCormick in GourMind

So, what have we learned so far? That ghrelin production is directly related to appetite in normals, but is unpredictable in post-bariatric surgery patients. And that studies of post-surgical patients in the U.S. and Sweden showed contradictory results. So let's throw in another variable - surgical procedure - as well as another location - Greece - and see what we can add to our narrative.First, a little background from a non-surgeon. Gastric bypass is a procedure in which the stomach is reduced........ Read more »

Understanding triple negative breast cancer – 53BP1 and the BRCA1 connection

by Cancer Research UK in Cancer Research UK - Science Update

Over the years, Cancer Research UK has helped transform breast cancer treatment – now 8 out of 10 women survive their disease for more than 5 years, compared with 5 out of 10 women in the 1970s. Most of this progress has been made in so-called hormone-sensitive cancers – those that are fuelled by the [...]... Read more »

Why it's time for the media to help our politicians believe they can succeed

by BPS Research Digest in BPS Research Digest

A psychology study fresh off the presses shows the importance of positive expectations for the successful resolution of awkward negotiations. The results couldn't be more timely as our senior politicians negotiate over terms for a new coalition British government - the first since the 1970s. The finding suggests that the media has a vital role to play. By fostering optimism in the likely success of the negotiations, the media could help increase the likelihood of a successful resolution.In an in........ Read more »

For the Love of the Game: A Look at Fans and Disappointment

by Krystal D'Costa in Anthropology in Practice

What does it mean to be a baseball fan? To exchange high fives with complete strangers utterly swept away with the exhilaration of a win? To sit in your car, despondent, after a devastating loss? What is the fan’s connection to this game—billed as America’s pastime?

Before delving into this post, it’s only fair to report that I myself am a fan. So this is in part a self-reflexive exercise to... Read more »

Tracking the Origin of Dinosaurs

by Brian Switek in Dinosaur Tracking

Almost everyone is familiar with the ongoing debate surrounding the extinction of the non-avian dinosaurs 65 million years ago, but the discussion over where dinosaurs came from in the first place is often overlooked. Hypotheses of dinosaur origins have been just as controversial as those of triggers for the end-Cretaceous mass extinction, but during the [...]... Read more »

rethinking petroleum a little too hard…

When you run a blog which focuses on skepticism and fact checking, you can occasionally discover that even a seemingly common, everyday, undisputed bit of science can have its detractors. About two months ago, two people who commented on my review of NatGeo’s dramatic what-if scenario about our future if all the oil in the [...]... Read more »

Mountains of Pelagic Diversity

by Alistair Dove in Deep Type Flow


If you ever saw the dramatic seamount scene in Blue Planet (and if you haven’t, where ya been??), then you are probably familiar with the idea that submarine mountains can attract lots of animals; as Attenborough puts it, they “create oases where life can flourish in the comparatively empty expanses of the open ocean”.  In that spectacular BBC sequence, jacks and tuna swarm an Eastern Pacific ...

Monday Pets: How Do Dogs Learn New Words?

by Jason Goldman in The Thoughtful Animal

...and what can word-learning in dogs teach us about the evolution of language in humans?

What is involved in the learning of a single new word? Consider the word "tiger", being learned by a child with already a modest vocabulary, at least for animal words. First the child must make a new entry in the mental lexicon - that "tiger" is a word in the first place. He has to categorize it as a noun. It has to be categorized under "animal" (a supernym) and related to its hyponyms, like "Sumatran tige........ Read more »
