A new study on snorkelers in the Mediterranean sea finds a rare piece of good news about human impacts on the marine environment.
Joachim Clauedet and fellow researchers looked at snorkeling within the Cerbère Banyuls Natural Marine Reserve in the French Mediterranean and found that the activity had no observable effect on the structure of fish or macroalgae communities.... Read more »

Back in the 1970s my parents had friends who had stacks of hi-fi separates with gold contact wiring and speaker stands on metal spikes. They were only playing Perry Como on vinyl, but that was their idea of fun, so good luck to them. When the CD emerged on to the market with its claims [...]Whatever happened to the audiophile? is a post from: Sciencebase Science Blog

As I’ve written recently, I don’t feel all that at home and comfortable in the field of neuroscience. I feel much more at home in the discipline of neuroethology, which investigates the neural bases of naturally occurring animal behaviour. It is populated by people who still appreciate diversity.
Having said that neuroethology is my intellectual home, I would like to rattle the windows in my own house a bit.
Neuroethology has a bunch of great people working on cool stories. And yet it is n........ Read more »

Vaccinia virus is a widespread virus whose natural host remains unknown. It turns out to be pretty good at jumping across species.
Vaccinia, of course, is the vaccine against smallpox. Even though smallpox is eliminated in the wild,1 vaccinia is still very widely used in research and even, to some extent, in [...]... Read more »

While there are plenty of theories on how music and emotion might be related (see Juslin & Västfjäll, 2008 for a overview), there is still little empirical support to decide on how far music and specific associated emotions - such as happiness, fear, sadness or anger - are merely a result of association and/or culturally determined, or in fact shared and a result of brain mechanisms that we all share. Last year Current Biology published an interesting study on the recognition of three basic em........ Read more »

In this paper from 2005 Sniehottaet al. examine why although some people develop an intention to change their health behaviour many do not follow through from intention to action. The gap between the intention and behaviour has been called the ‘‘intention–behaviour gap.’’ The authors examine factors which can be used to reduce the gap. They examine action planning, perceived self-efficacy, and self-regulatory strategies to investigate what effect these can have on reducing disparity........ Read more »

The Sunday Express has run a front page story stating that scientists have made a major breakthrough in cancer treatment “after cracking the ‘code’ behind the disease.” Sadly the story is actually only based on a theory rather than on concrete scientific evidence.

In recent years cognitive scientist Marc Hauser has gathered evidence that suggests we're born with a moral instinct. This moral intuition has been likened to the universal grammar that Chomsky famously suggested underlies our linguistic abilities - certain principles are set in stone, whilst the precise parameters can be set by culture. Thousands of people from multiple countries and different religions and demographic backgrounds have given their verdict on fictional scenarios presented online........ Read more »

Metabolism, which might be broadly defined as the biochemical process of living, is absurdly complex. The way in which metabolism varies between individuals, and then changes over time with aging? Even more complex. This is one of the reasons why slowing aging by changing metabolic machinery - in effect creating a new human metabolism - looks very much like an inferior, harder path in comparison to attempts to restore the metabolism we have to the way it operates in youthful bodies. Complexity i........ 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 »

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........
