A science blog from award-winning science writer David Bradley covering everything from astronomy to zoology by way of bio, chemistry, nano and physics
History teachers can always turn to the significant figures and battles to enliven their lessons, biology education has the enormously diverse range of species to point to, and even physics can pull in metaphors and anecdotes for the more esoteric aspects, try teaching gravity without mentioning Galileo and the Leaning Tower of Pisa. But, teachers [...]... Read more »
Who hasn’t received a spam email with some kind of clause laying claim to compliance with the CAN-SPAM Act of 2003? They usually say something about the message being anything but spam. But, it quickly becomes obvious, if you actually waste the time to read the content, that it is a generic marketing message for [...]... Read more »

why do leaves turn red in the fall? It's all down to chemistry. Red pigments known as anthocyanins form in leaves from many plant and tree species at the same time as the green photosynthetic apparatus is dismantled by the plant. New research in PNAS this week explains abscission - the how and when of leaf fall.... Read more »

Chernobyl. The very name strikes fear into the hearts of those who hate everything about the nuclear industry. It conjures up images of an archaic, burning industrial site spewing out lethal fumes, of farm animals dying of radiation poisoning in their thousands and contaminated meat, of ecosystems devastated, and of people with radiation sickness and [...]...

I recently wrote about how social media might help scientists do their work, so a paper in IJWBS on how those on the receiving end of medical science - patients and healthcare practitioners - might benefit from web 2.0 caught my eye.

Gossip and rumours, they are the life force of cultural interaction. Just ask Guy Kawasaki, whose Truemors.com website took off last year, the hundreds of hacks who peddle the minutiae of celebrity lifestyles complete with the Photoshopped products of the paparazzi, or Perez Hilton. But, there is a serious side to rumours. In the midst [...]... Read more »
As regular readers will be aware, I’m very skeptical of crank claims. Usually, these will claim to cure everything from premenstrual cramps to cancer by way of motor neurone disease and ingrowing toenails, all of them, with one pill. Forgive my flippancy, but the claims of many of those touting such panaceas usually beggars belief.

The Elucian Islands in the virtual online world known as Second Life are to host a climate change conference. Speakers will present live from Imperial College London and Stanford University in California, and researchers and university students will attend from the UK and the United States.
However, another climate change conference with a difference also begins [...]... Read more »

A radical plan to curb global warming and apparently reverse climate change caused by our rampant burning of fossil fuels since the industrial revolution would involve simply covering large areas of the world’s deserts with reflective sheeting.
The idea is discussed in detail in the January issue of the International Journal of Global Environmental Issues and [...]

There is much talk about Open Access. There are those in academia who argue the pros extensively in all fields, biology, chemistry, computing. Protagonists are making massive efforts to convert users to this essentially non-commercial form of information and knowledge.
Conversely, there are those in the commercial world who ask, who will pay for OA endeavours [...]... Read more »

We are, the media tells us, either on the verge or diving head first into a global recession the likes of which we have never seen. Countless financial headlines have screamed Credit Crunch, which sadly isn’t a wholegrain breakfast cereal for day-traders, for a year now. Banks are borrowing billions from taxpayers to allow them [...]... Read more »

Professors the world over are worried about plagiarism: students simply lifting huge chunks from web pages and passing the thoughts and arguments off as their own. Then there are the Professors who steal from each other and publish their work in supposedly novel research papers and books and present it at conferences as original. This [...]... Read more »

It’s a crude schoolroom axiom around which many an adult pub debate might also revolve: He who smelt it, dealt it.
However, there is a serious side to quickly locating the source of noxious odours in an indoor environment of varying airflow, as Zhenzhang Liu and Tien-Fu Lu of The University of Adelaide, Australia, will attest. [...]Post from: Sciencebase Science Blog... Read more »

A $2 egg-beater could save lives in developing countries, according to a report from the UK’s Royal Society of Chemistry. A piece of inexpensive plastic tubing taped to a handheld egg-whisk could be used as an ad hoc centrifuge for separating out blood plasma in a matter of minutes and allow life-saving diagnostic medical tests to be carried out much faster and at far less cost than with conventional lab-based centrifuge equipment....

Most internet users will be unaware and unconcerned by the computer science and technology that underpins their daily web surfing, emails, chats, and Twitter updates. But, there are, of course, thousands of incredibly bright people working behind the scenes to make the internet work. One aspect of the backroom work that goes on, is the [...]... Read more »
During my student days, one of the most obviously complicated and beyond-comprehension modules was that on fluid dynamics. It’s not surprising that it was complicated and beyond comprehension, the way fluids (gases and liquids by definition) move is not simple.

Years ago when BioMedNet’s HMSBeagle was still sailing the high seas, I wrote a feature for the Adapt or Die careers column on scientific jobs in museums, the feature, which is available on Sciencebase is still relatively valid, but one big aspect of museums that has changed significantly since the Beagle was abandoned in dry [...]...

For Scousers, Londoners, fans of BBC’s Have I Got News for You satirical news quiz, and especially to everyone who watched this Beijing to London Olympic handover this week the name Boris Johnson likely drums up an image of some blonde, floppy haired, bedraggled and totally confused Tory toff, who just happens to be Mayor [...]...

et al. (2008) Geography. Nature.
A discussion a while back, over a few beers, with a Buddhist friend about life, the universe, and everything (what else?) got around to the subject of null physics and the notion that the universe may always have existed and may exist for eternity to come.

In 2004, I did some reportage for the Royal Society from their meeting on emerging viral infections. The meeting was held just after the worldwide SARS outbreak that threw nations into chaos and had the more susceptible parts of the media hyping the end of the world. Of course, SARS, an emerging pathogen, was lethal [...]Post from: Sciencebase Science Blog... Read more »
