Open letter to anti-vaccinationists

by thomastu in Disease Prone

Some people have commented to me in person (and online) that I was a little brash in calling those violently opposed vaccinations as evil or ignorant. Also, that I might be completely shutting off dialogue and having people immediately list me as one of those pro-vaccination whores. I thought about this for a long time [...]... Read more »

Helper Microbes and Heavy Metals…

by microbialmodus in Microbial Modus

Last week, the American Society for Microbiology posted a story that caught my eye which highlighted the most recent work of Kim Lewis and his collaborators published in Chemistry and Biology in March (see citation below).  It caught my eye due to the term “siderophores” in the title.  You may be wondering why a strange [...]...

Monster pythons of the Everglades: Inside Nature's Giants series 2, part II

by Darren Naish in Tetrapod Zoology

Episode 2 of series 2 of Inside Nature's Giants was devoted to pythons (for an article reviewing ep 1, go here). Specifically, to Burmese pythons Python molurus. And, quite right too. Snakes are among the weirdest and most phenomenally modified of tetrapods: in contrast to we boring tetrapodal tetrapods with our big limb girdles, long limbs and less than 100 vertebrae, we're talking about tubular reptiles with a few hundred vertebrae, stretched organs, distensible jaws and total or virtual a........

Your Home: A Cancer Survival Tool?

by Kari Kenefick in Promega Connections

Research published in Cell, July 9, 2010, provides compelling evidence for an environmental component for cancer survival, that is a macro environmental component. While other studies have examined the effects of diet and exercise and even toxicological components on cancer susceptibility, Cao et al. studied mice living in an “enriched housing environment” that included more [...]...

Are "Antipsychotics" Antipsychotics?

by Neuroskeptic in Neuroskeptic

This is the question asked by Tilman Steinert & Martin Jandl in a letter to the journal Psychopharmacology.They point out that in the past 20 years, the word "antipsychotic" has exploded in popularity. Less than 100 academic papers were published with that word in the title in 1990, but now it's over 600.The older term for the same drugs was "neuroleptics". This terminology, however, has slowly but surely fallen into disuse over the same time period.To illustrate this they have a nice graph ........ Read more »

Human, quadruped: Uner Tan Syndrome, part 1

by gregdowney in Neuroanthropology

The photos that accompanied news releases about quadrupedal people living in Turkey, members of a family that allegedly could not walk except on hands and feet, looked staged when I first saw them. Three women and one man scrambling across rocky ground, the women in brightly coloured clothing, the sky radiant blue behind them, their eyes forward and backsides high in the air – like children engaged in some sort of awkward race at a field day or sporting carnival.
Members of a Turkish family ........ Read more »

My E. coli brother's keeper

by The Curious Wavefunction in The Curious Wavefunction

Would an anti-indole work?Antibiotic resistance is one of the best examples of evolution in real-time and it’s also one of the most serious medical problems of our time. Emerging resistance in bacteria like MRSA threatens to bring on a wave of epidemics that may remind us of past, more unseemly times.Given the threat that antibiotic resistance poses, it is paramount to understand the mechanisms behind this process. While considerable progress has been made in understanding the genetic basis of........ Read more »

In Southern Utah, a Hadrosaur Left Quite an Impression

by Brian Switek in Dinosaur Tracking

When Charles H. Sternberg and his sons excavated one of the first hadrosaur mummies ever found, in the summer of 1908, it was a major discovery. For nearly a century naturalists and paleontologists could only imagine what a dinosaur’s skin was like, but the Edmontosaurus the Sternbergs collected gave scientists an unprecedented look at the [...]...

How bacteria die - SGM series

by Lab Rat in Lab Rat

This is the second post of my SGM conference series and the topic is Microbial Death. I was very interested in this one as a topic, because the mechanisms that lead to bacterial death aren't something I've covered so much. It's generally assumed that antibiotics screw up whatever they target such that the bacteria can no longer survive, and when they aren't around the bacteria just keep dividing.There were two talks concerning antibiotics in bacterial death, the first addressing a theory that's ........

Dirty Browsers – Determining a menu for North America’s fossil camels

by Laelaps in Laelaps

Even with the young politician Jefferson Davis behind their adoption by the military, camels were a hard sell to the U.S. government. Along with other military men, Davis was convinced that camels could replace horses as the standard beasts of burden used by cavalry on the ever-expanding western frontier, but most congressmen and senators balked [...]...

Six Sigma Cola

European man, Y chromosomes & tea leaves

by Razib Khan in Gene Expression

Sometimes in applied fields artistic license is constrained by the necessity of function to particular creative channels. Architecture comes to mind, at least before innovative technologies produced lighter and stronger materials, freeing up form from its straight-jacket (whether this was a positive development is a matter of taste). But there’s only so much you can [...]... Read more »

Using models to link different varieties of data

by Becky in It Takes 30

One of the fundamental problems in systems biology is that many important decisions get made at the level of individual cells, but most of the measurement techniques we have (mass spectroscopy, Western blots…) report data on the behavior of populations.  And much of the time it’s hard to relate what you see on the single-cell [...]...

What happens when you teach monkeys to use money?

Freakonomics and its successor Superfreakonomics are two books by the economist Steven Levitt and his partner in crime Stephen Dubner that have a common theme running through them (quote): “People respond to incentives, although not necessarily in ways that are predictable and manifest.

Paucis Verbis card: Pertussis

by Michelle Lin in Academic Life In Emergency Medicine

Bordetella pertussisIs your Emergency Department administering Tdap immunization boosters instead of dT boosters? Patients with wounds are getting updated not only for tetanus and diphtheria, but also now for pertussis. Apparently there has been sharp rise in the national incidence of pertussis in 2010. The infection has been documented in both infants (underimmunized less than 3 months old) and adolescents/adults (loss of immunity after 10 years). In fact, the CDC has issued an epidemic warning........ Read more »

Plague among the nuts

David Woods was looking at the early Irish chronicles and he noticed something very odd. There are clusters of entries recording large mast crops. Mast? In Ireland, that would be mostly acorns..  In these sparse annals that normally only record battles, deaths,  and other major events, why record large acorn falls? The only typical use [...]...

Shore Crab, Sea Squirts, and Alzheimer's Disease

by Joris van Alphen in Joris van Alphen Photography Blog

(...) Although these adult sea squirts, or tunicates, don't consist of much more than translucent sacks with intestines, their larval "tadpole" stage exhibits all characteristics of the chordates. This means that they are actually more closely related to us chordate humans than this crab is!

In fact, transparent sea squirts are so similar to us that they may prove to be important for the development of more effective treatments for Alzheimer's disease.... Read more »
