Why the Soviets would fund a human-chimp hybridization program in the first place and what can be learned from this sordid tale of ethical misconduct is an important topic and fascinating in its own right. Ivanov represents a scientist, widely respected in his field, whose dedication to find out if something could be done blinded him to ask whether it should be done. It also reminds us of the role that politics can play in the development of scientific research even if the scientists directly in........ Read more »

Black holes are immensely fascinating cosmic phenomena. They’re not even objects but places where much of what we know about physics is put on its head, twisted forward, backwards, sideways, blended together in nearly infinite quantum states, spat out, and then sucked back into violent maelstroms of pure self-gravitating energy in a display of the [...]...

Einstein is accredited with saying “The important thing is not to stop questioning” while Euripedes apparently said “Question everything. Learn something. Answer nothing.” I’m sure of the origins of neither quote – but I think I must have inhaled both of them when I was a toddler because I have never stopped asking ‘why’! In … Read more... Read more »

Image via Wikipedia ADHD has traditionally been conceptualized in terms of deficits- that of attention , impulse control or motor restraint; but the new neurodiversity paradigm forces us to take a more balanced look and acknowledge the strengths that the ADHD kid may have- divergent thinking, spontaneity and high energy and vitality.

Previously, I plotted a grid of NASA GISS global temps in ggplot2 to show general trends by the brute force method. Here, I will again use the brute force method to do a simple power analysis on a portion of the data (data here). The general aim is to figure out what the minimum sample [...]... Read more »
Quasars are powered by the gravitational (potential) energy of their central supermassive black holes. However, their distinctive features – their extremely high luminosity in particular – are very dependent on characteristics of matter close to the black hole. Most supermassive black holes (SMBH), including those at the centers of the Milky Way and our close neighbor M31 (Andromeda), are responsible for fairly small amounts of radiation in any part of the electromagnetic spectrum.

Information technology is letting people around the world come together in unprecedented ways. Wikis, blogs and microblogs like twitter, crowdsourcing and crowd-task-solving sites continue to flatten the planet. Scientific innovation used to be a private endeavor, with very narrowly specialized scientists. The Internet changed some of this but there is plenty of room for improvement.... Read more »

British society, like that of most industrialized nations, has gone through enormous changes in recent decades. But it's hard to get objective data on what the impact has been on the people living there.
Which is why I was interested to see a recent study by Stephen Collishaw, of Cardiff University, and colleagues. They compared data from two studies, one in 1986 and one in 2006, that asked adolescents (aged 16-17) about their state of mind. Whether they felt anxious, depressed, worried, irrita........

Even in the world of the very small, there are significant differences in size. A eukaryote cell (i.e a human cell) for example is relatively big, in microscopic terms. Most other things that interact with the cell at the microscopic level, are far smaller than it, such as bateria, viruses and signalling molecules.A virus isn't much more than a small capsule of proteins with a little bit of DNA inside. Once it gets inside a eukaryote cell, it's very much in the position of a small child wanderin........ Read more »

A lot of the media (and scientific) attention to oil spills in the ocean focuses on the effects on marine ecosystems. The ecological effects, particularly in the short term, are undeniable – the pictures of oil-soaked birds are an obvious example. However, less attention is given to the potential effects on human health – both [...]... Read more »

A biofilm is generally described as a ‘synthesised environment housing a bacterial community on a surface’. This essentially means that organisms (not just bacteria) start to produce huge amount of ‘muck’ containing proteins, sugars and DNA and export it from the cell once bound to a ‘surface’. When it does this it generates its own little environmental niche and as that bacterial cell divides within the biofilm it can pool its resources allowing easier growth........ Read more »

The best headline I read last week is from Metafilter blog: "Scientists prove that lunch came before breakfast." In fact, journalists at major news sites all around the web reported that scientists have solved the infamous chicken-and-egg problem.
Which came first? The chicken. Definitively.

We have been told that feeling well-rested while studying and reviewing your work just before bedtime enhances your memory for what you have studied. But when it comes to the role of sleep in motor memory, the answer is less clear.
