Danger, Will Robinson!!! or injury prevention with sensors and algorithms

by Aurametrix team in Health Technologies

Injuries are most likely to be  perceived as “acts of fate”,  but they depend on the same determinants as other health factors: individual behavior, social and physical environment.  The likelihood of injuries -  unintentional ones and those caused by acts of violence - can be computed from physical location, gene-environment interactions, prior medical history, and physical traits. There are many ways to prevent injuries - just say "no" to risky behaviors, wear preventative gear while p........ Read more »

Neury Thursday: Progress in Basic Neuroscience

by Allison in Dormivigilia

Scientists have NYU have advanced our understanding of basic neuroscience by observing that GABA interneurons in the neocortex are co-expressed with serotonin receptors. There is great therapeutic potential behind this discovery because GABA interneurons modulate the strength of excitatory and inhibitory signaling of the neuron-types projecting onto these interneurons....

Of Political Orgasms and the Scientific Method

by David Berreby in Mind Matters

This week's theme is epistemological unease in the sciences: Complaints in a number of disciplines that studies didn't really find the effects they're reporting. One reason for these worries is that many studies nowadays are never repeated. So today I'm going to consciously and rationally resist ...Read More

Wolves at the Door: Shark Interactions with Aquaculture

by Chuck in Ya Like Dags?

In the greater spectrum of shark/human interactions, the majority of encounters undoubtedly take place between sharks and fishermen, even if encounters between sharks and swimmers get all the press.  However, that aquaculture is becoming more widespread as a use of … Continue reading →...

A Little More on Lipophilic Chemicals, Diabetes and Obesity

by ABK in Environment and Health

This is just a little continuation of the post made yesterday in which I wondered if associations between intake of animal protein (vs. vegetable protein) and waist circumference had anything to do with increased exposure of consumers of animal products to environmental contaminants. This is not my area of research . . . but it is an area of research for a lot of other people. Diabetes and/or Insulin Resistance is associated with exposure to Brominated Flame Retardants, Persistent Organic Poll........ Read more »

Parasitic worms paint warning colours on their hosts using glowing bacteria

by Ed Yong in Not Exactly Rocket Science

A robin flying over a field sees a juicy caterpillar on a leaf. It dives in for a closer look but it notices something strange: this larva is bright red and glowing slightly. Red means danger – this caterpillar is probably toxic and is best avoided. The robin leaves; the caterpillar apparently lives. But this [...]... Read more »

The Kids Are Alright: New Genes Can Be Essential

by Rob Mitchum in ScienceLife

When it comes to genes, evolutionary biologists have traditionally favored seniority. Genes thought to be most essential to life must be ancient and conserved, the assumption goes, handed down from species to species as the basic instructions of life. That sharing is evident in early developmental stages, which 19th-century biologist Ernst Haeckel observed to be [...]... Read more »

Juravenator: Germany’s Other Feathered Dinosaur

by Brian Switek in Dinosaur Tracking

In 1861, as debates about evolution were brewing among naturalists, two important skeletons were discovered from the Late Jurassic limestone quarries of Germany. Both would be relevant to ideas about how birds evolved. Although not recognized as such until the late 20th century, Archaeopteryx was the first feathered dinosaur ever discovered and was a confirmation [...]... Read more »

The Rosetta macromolecular modeling suite has a very wide range of applications, and although installing and running Rosetta, becomes increasingly easier over the years, some non-experts would still prefer to run it over a comfortable to use web-server. We have assembled here the list of Rosetta applications for which such a web-server exists. Bookmark for future modeling tasks.

Analyzing DNA to Determine a Person’s Age

by Terri Sundquist in Promega Connections

People have employed many methods to disguise their age: eating a healthy diet rich in antioxidants, exercising regularly, protecting their skin from the sun and, if all else fails, undergoing plastic surgery. However, a recent Current Biology paper may make it harder for us to hide our true age. The authors describe a real-time PCR [...]... Read more »

Doctors happier to prescribe sex drugs than smart drugs

A new survey of family doctors in North America has found that they are more comfortable prescribing viagra than modafinil or ritalin. The new study in PLoS ONE was conducted by Opeyemi Banjo, Roland Nadler and Peter Reiner, three neuroethicists at the University of British Columbia in Vancouver. They were interested in doctor’s attitudes to pharmacological cognitive enhancers (or smart drugs as we stupid people call them)... Read more »

Guest post: A new link between ontogeny and phylogeny

by Becky in It Takes 30

Jeremy Purvis writes: I once had an English professor in college who began class by writing the phrase “ontogeny recapitulates phylogeny” on the blackboard. He then began to explain—in English-professor terms—how embryos pass through stages of development that closely resemble successive stages in their own evolution. Though I can’t remember exactly, I believe this introduction [...]... Read more »
