Well, I'm trying to read a paper a day (this can be really hard with 2 kids and a job that doesn't encourage it), and today I randomly pulled up this paper: Johnson and Host "Recent developments in landscape approaches for the study of aquatic ecosystems" (full cite below). Let's just say that there's a lot here. Basically, this paper is part of a big-time retrospective done by J-NABS in ... Read more »

It is a common argument by those who are opposed to evolution's implication for religious belief to label Darwin as a social Darwinist and a racist. Adrian Desmond and James Moore's book Darwin's Sacred Cause has gone a long way towards dispelling any claims that Darwin sought to justify black inferiority (in fact, as they show, it was just the opposite). However, the claim that Darwin inspired social Darwinism is a persistent argument and those that proffer it will stoop to any level in order........ Read more »

A study has found that regular use of common painkillers – such aspirin, paracetamol, and ibuprofen – increases the risk of hearing loss in men aged 40-74 years.
Using aspirin, non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, or paracetamol twice a week or more over a 20 year period increased the risk of hearing loss by 12%, [...]... Read more »
I sometimes wonder if we have all been hoodwinked about the whole Roman Colosseum stories of thousands of supposedly normal everyday Romans, presumably wearing sandals (not that that is important to this), cheered on as their fellow humans were slain, eaten, speared and mutilated. Then again, cage fighting, described by Senator John McCain as human [...]... Read more »

High Throughput Screening (HTS), with all its strengths and limitations, is still the single-best way to discover novel interesting molecules in drug discovery. Thomas Kodadek of Scripps Florida has an interesting article on screening in the latest issue of Nat. Chem. Biol which is a special issue on chemical probes. Kodadek talks about the very different properties required for drugs and probes and the limitations and unmet needs in current HTS strategies. He focuses on mainly two kinds of scre........

In an effort to conserve and research the endangered Virginia big-eared bat, the Smithsonian’s National Zoo took in 40 bats in November 2009. The goal was to establish a security population and to scientifically develop husbandry practices in a subspecies that researchers have not attempted to conserve before. ... Read more »

A simplified evolutionary tree of primate relationships showing the placement of Darwinius in relationship to other groups. From Williams et al., 2010.
The study of human origins can be a paradoxical thing. We know that we evolved from ancestral apes (and, in fact, are just one peculiar kind of ape), yet we are obsessed with the features that distinguish us from our close relatives. The "big questions" in evolutionary anthropology, from why we stand upright to how our brains became so larg........ Read more »

Applied ecology is the science of minimizing human impacts and of supporting ecological systems in an economic landscape. Often though, applied ecologists work in isolation from those economic forces shaping biological landscapes, not really knowing what businesses would like to accomplish for habitat protection or sustainability. At the same businesses are seldom aware of the knowledge, tools and insight provided by ecologists. And perhaps, greater interaction could help turn ecology into a sci........ Read more »

Chronically stressful life events have been shown to lead to depression. Chronic stress leads to hyperactivity of HPA axis leading to more glucocorticoids (cortisol) in the human body. This excess cortisol in term is proposed to underlie the affective symptoms of depression. Also, depressive people have been found to have up to More >Rating: 0.0/10 (0 votes cast)

The ability to read emotions is an important part of the human experience; the only way to successfully navigate through complex social environments. It comes in handy especially if you don the title of psychotherapist or professional poker player. Without it, you become socially inept.

The question for neuroscience is how nervous systems generate behaviour and cognition. In general, we think there’s a hierachical command scheme, as the quick and dirty sketch below shows.
It’s been hard to move from general principles and “black boxes” to real neurons. A good chunk of effort in neuroethology has gone into understanding the sensory capabilities of different animals, and cracking how pattern generators could generate the detailed plan for movements, especially rhythmic ........

We know that lots of genes are involved in cancer progression. For example, you’ve probably read something like “scientists have found the gene for such-and-such cancer” or something similar. What does that really mean? Are there really genes which cause cancer? And why do we have those genes anyways, if that’s all they do?
