On April 26, 1986, the world’s worst nuclear power plant accident occurred at the Chernobyl nuclear power station. Now, 25 years later, the current crisis in Fukushima is being called the “worst since Chernobyl.” Will we avoid another disaster? And further more, in another 25 years, how will we feel about nuclear energy?

In my last two posts I’ve introduced the notion that DNA acts as a store of biological information; this information is stored in a series of chromosomes, each of which are divided into a number of genes. Each gene in turn contains one ‘snippet’ of biological information. But how are these genes actually used? How is the information stored in these genes actually extracted to do something useful (if ‘useful’ isn’t too flippant a term for something that the very continuation of life depends upon).
Tweet By Charles D. Ferguson The ongoing Japanese nuclear crisis underscores yet again the risks inherent in this essential energy source. But it should not divert nations from using or pursuing nuclear power to generate electricity, given the threat from climate change, the health hazards of fossil fuels, and the undeveloped state of renewable energy.

European robins are crafty little creatures. Each year they make a round trip from the cold Scandinavian Peninsula to the warm equatorial planes of Africa, a hazardous trip of about four thousand miles each way. Armed with only their internal sense of direction these diligent birds regularly make the journey without any fuss.
“Physics, most of us would agree, is the basic science of nature. Its purpose is to discover the laws of the natural world. Do such laws exist? Well, the success of physics at identifying some of them proves, in retrospect, that they do exist. Or, at least, it proves that there are Laws of Physics, which we can safely assume to be Laws of Nature.”

I described in my last blog post how DNA acts as a store of biological information – information that serves as a set of instructions that direct our growth and function. Indeed, we could consider DNA to be the biological equivalent of a library – another repository of information with which we’re all probably much more familiar. The information we find in a library isn’t present in one huge tome, however. Rather, it is divided into discrete packages of information – namely books. And so it is with DNA: the biological information it stores isn’t captured in a single, huge molecule, but is divided into separate entities called chromosomes – the biological equivalent of individual books in a library.

Deep questions of existence have entertained both sharp and dull minds throughout the history of humanity. Where did it all come from? What is the point of it? What happens after you die? Great mounds of implausible speculation have been tipped on these pressing questions by theologians and philosophers; whole churches have been founded as a result of the institutionalization of the answers. But all those answers were guided by speculation and sentiment and typically expressed in compelling language that captured minds but concealed emptiness. They were emperor’s new clothes with no emperor within.
Peter Atkins is the author of almost 60 books, including Galileo’s Finger: The Ten Great Ideas of Science, Four Laws that Drive the Universe, and the world-renowned textbook Physical Chemistry. His latest book is On Being, which is a scientist’s exploration of the great questions of existence. In the below video, Atkins is in conversation about the book with Meet the Author‘s David Freeman.

Émilie du Châtelet, wrote Voltaire, ‘was a great man whose only fault was being a woman.’ Du Châtelet has paid the penalty for being a woman twice over. During her life, she was denied the educational opportunities and freedom that she craved. ‘Judge me for my own merits,’ she protested: ‘do not look upon me as a mere appendage to this great general or that renowned scholar’ – but since her death, she has been demoted to subsidiary status as Voltaire’s mistress and Isaac Newton’s translator.
Today we’d like to introduce our latest regular OUPblog column: SciWhys. Every month OUP editor and author Jonathan Crowe will be answering your science questions. Got a burning question about science that you’d like answered? Just email it to us, and Jonathan will answer what he can. Kicking us off: What is DNA and what does it do?
Philosophers have long argued that sound, colour, taste, smell and touch, exist only in our minds. We have little basis for our assumption that these qualities represent reality as it really is. So, if we interpret the word ‘sound’ to mean a human experience, then the falling tree really is silent.

It began with the sound of a tyre rim grinding on the surface of the cycle path I’d been travelling along, and a sudden sensation of being on a bike that was moving through treacle rather than through air. My rear tyre had punctured and, not for the first time of late, I found myself resenting the seeming futility of life: of having the bad luck to get the puncture, of having to spend time and effort buying and fitting a new inner tube – of my life being enriched not one iota by the whole experience.

In “Quantitative Analysis of Culture Using Millions of Digitized Books” (Michel, et al., Science, Dec. 17, 2010), a Harvard-led research team introduces “culturomics” as “the application of high throughput data collection and analysis to the study of human culture.” In plain English, they crunched a database of 500 billion words contained in 5 million books published between 1500 and 2008 in English and several other languages and digitized by Google. The resulting analysis provides insight into the state of these languages, how they change, and how they reflect culture at any given point in time.

There are few more important issues at the present time than that of climate change – whether it is real, what we can expect to happen, when and what if anything we can do to prevent or at least ameliorate it. Climate is a ‘crossover’ topic: the facts are mostly in the domain of the scientist, and need special training before they can be understood. However, everyone faces the consequences, perhaps especially people in poor, relatively illiterate counties who already survive on the ragged edge of sustainable agriculture. Finally, if the scientists are to be believed, the politicians must act, and not just by fiddling around the edges of the problem: the changes required are almost unbelievably extensive, expensive, and disruptive. George W. Bush came across as a climate skeptic not because he didn’t believe the science (he wasn’t sure, one way or the other) but mainly because he didn’t want to stifle his nation’s competitiveness by curbing its carbon emissions on the draconian scale the green activists were calling for.
Yesterday, I tried to start a #mathbattle on Twitter, but it proved too geeky to take. (Go figure.) I was having a nostalgic moment, remembering back in middle school when we had to write date equations. Everyday. Because each day, my friends, is different. A new day, full of new possibilities, opportunities, and numbers. Today is 7/30/2010. That means two things:
1) It will be August very, very soon.
2) We have the numbers 7, 3, 0, 2, 0, 1, 0 to work with. (Or, you can leave out a 2 and a 0. That is the cheater’s way.)
LET’S DO IT! —> 7 – ((3+0)(2 + 0)) = (1 + 0)
Yessssss. Math is awesome. Got a better equation? Prove it. Until then, here are some interesting things.
Why is infinity important?
