A FEW years ago, a Boston University team headed by Jim Collins published findings that suggested the means by which bactericidal antibiotics result in cell death, irrespective of the initial cellular target of the drug, was by stimulating the production of hydroxyl radicals, a reactive oxygen species 1. The hydroxyl radical is known to cause [...]... Read more »

Seriously, this is what I first thought when I saw the cover of this week’s Nature, and the associated drawings in the press. The dude’s haircut seems like it was even bad in the ’80s… 2080 BCE that is, which is when his body is dated. Approximately.

When I give lectures about the global food supply and the environment, someone in the audience will often comment that the best way to solve the problem is to quit producing so much food.
I find this type of "Let 'em starve" approach quite horrific from a humanitarian view. It also makes no sense scientifically.

Swiss researchers have discovered that bright sunlight exposure can elicit 'photic sneezing" which is characterized by the co-recruitment/hyperactivation of visual and somatosensory cortices. Though the researchers define it as a reflex, it is an anomalous reflex in that it requires activation of cortex unlike the classical knee-jerk reflex and others which only necessitate the activation of spinal cord interneurons ...

I'm studying sacrificial deposits made by people of a lo-tech culture in Sweden 3000 years ago, largely in wetlands. This was long before any word relevant to the area was written. The objects were mainly recovered during the decades to either side of 1900. Yesterday while trawling through back issues of the Journal of Wetland Archaeology I came across a really cool paper on a similar theme. It's about wetland deposits made by lo-tech people and excavated during the 20th century. But in this cas........ Read more »

When many of us think of viewing things under a "black light," we either think of those psychedelic posters from the 1960s or else the displays of fluorescent minerals that nearly every science museum has. It's also virtually mandatory to have a scene involving the use of "black light" in the popular CSI television programs - many bodily fluids show up nice and pretty under these conditions. "Black light," more properly known as "ultraviolet (UV) spectrum light", is just outside the visible ligh........ Read more »

You may not have heard of the American Pika. Pika are small little rodent relatives most closely related to rabbits, though they look chinchilla-esque. They're native to colder climates all over the world, including Asia, Europe and North America, and they tend to live on rocky mountain slopes where they can hide in small crevices. Because they are adapted to cold mountainsides, the pika are particularly at risk is the global climate warms, as changing temperatures could push them further and f........ Read more »
...the invasive could theoretically replace the native with little ill effect to the ecosystem; the invasive could fill the niche left void by the out-competed native plant without disrupting the energetics of the plant community as a whole. BUT, at the same time, a newly arrived invasive species may have a distinct advantage over a native transient because it is completely foreign to the ecosystem. For example, being unrecognized by its new environment the invasive may, for a period of time, ........ Read more »

I’ve been expecting a resurgence of swine-origin influenza virus (SOIV) in North America for a while now, and it hasn’t happened. The virus is still out there, still infecting a few thousand people per week, but there hasn’t been a third large-scale wave of virus transmission. That’s different from the 1918 and 1957 [...]...

These little bejeweled cases might look strange, but they're incredible. No, they're not some kind of special modern art. They're incredible because they're made by an insect.
I'm not much of a bug lover, but this is simply one of the coolest things I've ever seen (in a totally-bio-nerdy kind of way).

In the wild, caddisfly larvae create elaborate protective tubes from materials........ Read more »
“The dramatic rise in prescriptions [of psychotropics for children and young adults] has alarmed several commentators,” according to Lakhan and Hagger-Johnson. In their article, they trace this problem to five erroneous myths that influence prescribing: 1) Children are little adults. During adolescence, the brain changes rapidly. As a result, therapeutic benefits, potential adverse occurrences, and drug interactions [...]... Read more »

We have to wait, patiently, for the DSM-V people to cough up their system for ranking and classifying all autistics according autism "severity." In the meantime, some recently reported data are worth mulling over. First, here is the most current DSM-V autism "severity" ranking-system proposal, and here is my response, including information about instruments commonly claimed to measure autism "severity." The DSM-V void in this area can be located here. An increasingly prominent measure of autism ........ Read more »

When you smoke pot, you get stoned.Simple. But it's not really, because stoned can involve many different effects, depending upon the user's mental state, the situation, the variety and strength of the marijuana, and so forth. It can be pleasurable, or unpleasant. It can lead to relaxed contentment, or anxiety and panic. And it can feature hallucinations and alterations of thinking, some of which resemble psychotic symptoms.In Central nervous system effects of haloperidol on THC in healthy male ........ Read more »
