Tuesday Crustie: Indiscriminate?

by Zen Faulkes in NeuroDojo

Male fiddler crabs spend a lot of time doing this sort of thing:

This is Uca mjoebergi, a colourful crab from south Pacific shores. They're signalling to someone - but to whom?. To their own species? Their own sex? To predators?

I had fun recently giving a talk about fiddler crab signalling at a local nature center. I had seen a decent amount of research on fiddler crabs, but had never had the opportunity to review it and try to pull it into a story before. And while I was doing that, a new p........ Read more »

Low-energy effective Yang-Mills theory

by Marco Frasca in The Gauge Connection

As usual I read the daily from arxiv and often it happens to find very interesting papers. This is the case for a new paper from Kei-Ichi Kondo. Kondo was in Ghent last year (here his talk) and I have had the chance to meet him. His research is on very similar lines as mine. [...]... Read more »

When what you see is what you get: the consequences of the objectifying gaze for women and men From Psychology of Women Quarterly Women who are looked at as sexual objects not only react as sexual objects, they also exhibit less proficiency with math, according to this research.

Ten Tips for Adult Learning

by Dr Shock in Dr Shock MD PhD

These ten tips are from an article for surgeons but the ten tips are also applicable for all forms of adult education. Especially in training residents the hidden curriculum and ad hoc events occurring in a convenient pause in the hectic daily activity are important educational encounters. In this day and age medical training should [...]

Unintentional Shark Tagging

by Chuck in Ya Like Dags?

This might possibly be the most awesome paper about tagging fish ever. One of the handiest advances in telemetry, especially of large, highly-migratory oceanic species, has been the advent of SPOT tags.  These tags do it all: movement, depth, temperature, … Continue reading →... Read more »

The Three T’s: Treating Tolerant Tuberculosis

When I was growing up there was a right of passage every 13-year-old child had to go through: The B.C.G. vaccination against tuberculosis. We all stood in line and waited for our “six-pricks” (Heaf) test, and then a week later had the test site inspected to see if we needed the vaccination. Since T.B. was [...]... Read more »

Future of Spaceflight: No single point sollution

by FrauTech in Design. Build. Play.

Too often we look for a single perfect answer to our problems. In the energy crisis people are often disappointed when hybrid batteries are found to be so environmentally unfriendly or that wind power is often incredibly harmful to local bird life or that solar cell arrays often use a lot of water in areas that are pretty arid to begin with.Researchers looking into the future of space flight looked at combining a rocket propellant with an electric sail. An electric sail has some similarities to ........ Read more »

It’s all in your head: a review of The Belief Instinct by Jesse Bering

by Anna Goldstein in Berkeley Science Review Blog

I've been a voracious reader lately—a cookie monster of the written word. It started with Mysteries of Pittsburgh by Michael Chabon, and continued with The World Without Us by Alan Weisman (which I reviewed here) alongside The Hunger Games by Suzanne Collins (yes, I am still a young adult, thank you very much). The latest to be devoured was The Belief Instinct by Dr. Jesse Bering.

I first found Dr. Bering's work reading his often hilarious, always insightful blog Bering in Mind, and it was sc........ Read more »

A Viral Pyramid Scheme

by Merry Youle in Small Things Considered

In order to release their newly assembled virions, most viruses lyse the cells that have fed and housed them. This lysis is not a haphazard affair. Some phages, for example, employ a holin-endolysin system to rupture their host's cell membrane and digest the cell wall at a precisely controlled time. (For our earlier posts about this, click here and here.) Others instead interfere with cell wall synthesis—the same strategy that we use with our β-lactam antibiotics. Now yet another completely d........ Read more »

OpenLab 2010 – Gut bacteria in Japanese people borrowed sushi-digesting genes from ocean bacteria

by Ed Yong in Not Exactly Rocket Science

This post was originally published on 7 April 2010. I am reposting it in honour of the release of Open Laboratory 2010, which has just come on sale. It’s an anthology of great blog posts from last year, including this one.
Japanese people have special tools that let them get more out of eating sushi than Americans can. They are probably raised with these utensils from an early age and each person wields millions of them. By now, you’ve probably worked out that I’m not talking about c........ Read more »

Analysis of Logistics Strategies from 1990 to 2008

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Do supply chain strategies evolve over time? Are there the same strategic options nowadays compared to 20 years ago?
Since at least the meaning of the term logistics has evolved during the last 20 years, especially due to the emergence of supply chain management, logistics and supply chain management are used interchangeable in this article.

In 1987 Bowersox and Daugherty created a logistics strategy framework, concluding that there are basically three SC strategies:

Put Your Jury Selection on Steroids by Leveraging Pretrial Research: Lessons from the Barry Bonds Trial

by Persuasion Strategies in Persuasive Litigator

This post is focused on bulking-up your ability to target high-risk jurors and performance enhancing your voir dire. So speaking of steroids, lets start with Barry Bonds. Jury selection for the perjury trial of the former San Francisco Giants power-hitter, charged with lying to a grand jury over steroid use, starts this week. Prospective jurors will fill out a 19-page questionnaire focusing on the factors that both sides believe should help to reveal bias and guide the process of exercising c........ Read more »

The Secret World of Microbes

by Rob Mitchum in ScienceLife

Since the time of Linnaeus, scientists have loved classifying the world around them. But while centuries of biologists have worked to collect and categorize the plants and animals of Earth, all that work likely only covers about a minute fraction of our planet’s life. As much as 99 percent of the biodiversity on Earth is [...]... Read more »

Oxalaia: Brazil’s New, Giant Spinosaur

by Brian Switek in Dinosaur Tracking

Paleontologists have not found much of Oxalaia quilombensis. A fragment of the snout and a portion of the upper jaw are all that is known of this dinosaur. Even so, those two parts are enough to know that Oxalaia was one of the peculiar predatory dinosaurs known as spinosaurs, and a giant one at that. [...]... Read more »

Of southern African wing-gland bats, woolly bats, and the ones with tubular nostrils (vesper bats part IV)

by Darren Naish in Tetrapod Zoology

Time to continue our trek across the vesper bat cladogram. In the previous article we looked at the bent-winged bats (or miniopterids, or miniopterines): a highly distinctive, morphologically novel group that seem to have diverged from vesper bats proper something like 45 million years ago. Their distinctive nature and long history of isolation relative to other lineages conventionally included within Vespertilionidae mean that bent-winged bats are now argued by many to be worthy of 'family' s........
