Parasites keep red tides at bay
by Ed Yong in Not Exactly Rocket Science
Over the past decade, some coastal waters have started turning red with alarming frequency. The cause is not some Biblical plague, but dense concentrations of microscopic algae called dinoflagellates. Red tides can often contain more than a million of these cells in a mere millilitre of water. Many are harmless and essential parts of the ocean environment, but others produce toxins that can kill local wildlife and risk the health of humans who eat their poisoned flesh.

Friday Weird Science: Of Mice and...Seals?

This SHOULD be the time when I'm working crazy hard on InAdWriMo, trying to get those paper drafts up and running (ideally they should be ready on MONDAY).

The smallest possible eye
by Jeremy Yoder in Denim & Tweed
The eye is the original instance of "irreducible complexity," a biological structure supposedly too complicated to have evolved by undirected mutation and natural selection. Darwin made a point to deal with the evolution of the eye in The Origin of Species. He argued that, in spite of appearances, a surprisingly complete gradation of eye complexity is seen in nature, and it's not too hard to connect the dots.... Read more »

Cool Three-In-One Reaction
by Steve W in Bridgehead Carbons
Since I teach sophomore organic chemistry, I'm always interested to see new research that involves basic organic reactions that I cover in class. A new reaction using alkynyl halides produces alkynyl epoxides in a one pot procedure as a result of three different reactions. At first glance, this looks like a complicated reaction, but everything involved is routinely taught in standard organic chem classes.... Read more »

The role of self-esteem in Obama's electoral success

Voters are more willing to vote for male political candidates whom they perceive to have high self-esteem - a finding which could help explain President Elect Barack Obama's electoral success.In Autumn 2007, Virgil Zeigler-Hill and Erin Myers asked 209 undergraduates to rate the self-esteem of the eight potential democratic candidates for president (including Hillary Clinton and Barack Obama) and the ten republican candidates (including John McCain and Mitt Romney), and to also indicate their wi........

Hearing Involves Sound Physics
by AmiyaSarkar in Physiology physics woven fine
The way we hear sound is complex. The different attributes of sound (namely, intensity, frequency, the direction from which it is coming etc.) are faithfully perceived in the auditory cortex. The whole procedure may seem rather straightforward, but it is far more complicated than what looks so deceptively simple.The sound waves (say from an orchestra) impinge on our eardrums. Sound waves are mechanical waves consisting of condensation and rarefaction, things we learned in our school days. These ........ Read more »

Pediatric NICU Survival for Extremly Pre-Term Infants

Seeing shapes in two different ways: how and when it happens
by Dave Munger in Cognitive Daily
A Necker cube is bi-stable figure, meaning that it can be perceived as two different three-dimensional objects, depending on how you look at it:
Cube A is ambiguous -- the true Necker cube. Cube B and cube C show the two ways you can perceive the Necker cube: either the bottom of the cube is in front, or the top is in front. What's interesting about figures such as the Necker cube is that once you're aware of its bi-stable nature, it's impossible to see it only one way. Don't believe me? Then t........ Read more »

Deep Brain Stimulation Cures Urge To Break Glass

Deep Brain Stimulation (DBS) is in. There's been much buzz about its use in severe depression, and it has a long if less glamorous record of success in Parkinson's disease. Now that it's achieved momentum as a treatment in psychiatry, DBS is being tried in a range of conditions including chronic pain, obsessive-compulsive disorder and Tourette's Syndrome. Is the hype justified? Yes - but the scientific and ethical issues are more complex, and more interesting, than you might think.Biological Psy........ Read more »

"then follow the corner round until you reach the park, then second right, then first left, you can't miss it" ... You nod and thank them politely while panic privately sets in.

Optogenetic therapy for spinal cord injury
by Mo in Neurophilosophy
Optogenetics is a recently developed technique based on microbial proteins called channelrhodopsins (ChRs), which render neurons sensitive to light when inserted into them, thus enabling researchers to manipulate the activity of the cells using laser pulses.
Although still very new - the first ChR protein was isolated from a species of green algae in 2002 - optogenetics has already proven to be extremely powerful - it can be used to switch neurons on or off in an extremely precise manner ........ Read more »
