What makes this World AIDS Day different from all others?

By Kenneth Mayer
Last year, on World AIDS Day, U.S. President Barack Obama set ambitious goals to reach more people with treatment and fundamental prevention. Echoing U.S. Secretary of State Hillary Clinton’s call for an “AIDS-free generation,” he envisioned a tipping point in a 30-year battle to subdue the world’s costliest epidemic. This World AIDS Day, the administration’s release of a global AIDS roadmap takes the vision into practice.

The truth about anaesthesia

What do anaesthetists do? How does anaesthesia work? What are the risks? Anaesthesia is a mysterious and sometimes threatening process. We spoke to anaesthetist and author Aidan O’Donnell, who addresses some of the common myths and thoughts surrounding anaesthesia.

What sort of science do we want?

By Robyn Arianrhod
29 November 2012 is the 140th anniversary of the death of mathematician Mary Somerville, the nineteenth century’s “Queen of Science”. Several years after her death, Oxford University’s Somerville College was named in her honor — a poignant tribute because Mary Somerville had been completely self-taught. In 1868, when she was 87, she had signed J. S. Mill’s (unsuccessful) petition for female suffrage, but I think she’d be astonished that we’re still debating “the woman question” in science.

Summing up Alan Turing

By B. Jack Copeland

Three words to sum up Alan Turing? Humour. He had an impish, irreverent and infectious sense of humour. Courage. Isolation. He loved to work alone. Reading his scientific papers, it is almost as though the rest of the world — the busy community of human minds working away on the same or related problems — simply did not exist.

Moral cost of occupation for the occupiers

By Daniel Bar-Tal and Izhak Schnell
While many countries moved towards termination of occupation, colonialism, and imperialism, Israel still continues the prolonged occupation of West Bank and part of Golan Heights, and partially controls Gaza Strip. It appears that the prolonged occupation bears harsh moral, social, and psychological consequences, not only for the occupied population, but to the occupying society as well. Prolonged occupation refers not only to a statutory or geographical situation, but also inherently carries with it moral and socio-psychological meanings.

‘Zombie drugs’

By Dr Rosie Harding & Dr Elizabeth Peel
According to official statistics, a significant minority of people living with dementia are prescribed antipsychotic drugs. The 2012 National Dementia and Antipsychotic Prescribing Audit suggests that there has been a fall in the prescription of these medications. However, less than half of GP practices in England participated and thousands of people with dementia are still prescribed antipsychotic drugs each year. What many perhaps don’t know is that only one antipsychotic (Risperidone) has actually been licensed for use in elderly people with dementia.

The Brain Supremacy

By Kathleen Taylor
Ours is a world full of science. Much of that technology and knowledge, from mobile phones to the understanding of gravity, currently comes from what we call ‘the natural sciences’: those which study the material universe. In school, we learn to distinguish physics, chemistry, geology, and their natural kin from life sciences like biology and psychology. Our ideas of what science is, and indeed what we are, have been shaped accordingly. The brain supremacy, that coming era in which neuroscience will challenge physics for cultural dominance, is about to reshape those ideas as never before.

On animals and tools

By Robert St. Amant

Try this experiment: Ask someone to name three tools, without thinking hard about it. This is a parlor game, not a scientific study, so your results may vary, but I’ve done this dozens of times and heard surprisingly consistent answers. The most common is hammer, screwdriver, and saw, in that order.

Marian Stamp Dawkins on why animals matter

There is an urgent argument for the need to rethink animal welfare, untinged by anthropomorphism and claims of animal consciousness, which lack firm empirical evidence and are often freighted with controversy and high emotions. With growing concern over such issues as climate change and food shortages, how we treat those animals on which we depend for survival needs to be put squarely on the public agenda. Marian Stamp Dawkins seeks to do this by offering a more complete understanding of how animals help us.

Art and human evolution

By Stephen Davies
Young children take to painting, singing, dancing, storytelling, and role-playing with scarcely any explicit training. They delight in these proto-art behaviors. Grown-ups are no less avid in extending such behaviors, either as spectators or participants. Provided we have a generous view of art, we all engage routinely and often passionately with it.

Spitting blood: the absence and presence of tuberculosis

By Helen Bynum

Flying back from Boston recently I was delighted to be able to watch the 2008 film version of Frost and Nixon. I had greatly enjoyed the play in London and heard the film was also very good. So I plugged in the headphones and settled back.Before too long ex-president Richard Nixon is telling would-be interviewer David Frost how he bonded with his Russian counterpart Nikita Khrushchev over their shared sadnesses: Nixon had lost two brothers to tuberculosis.

Giant pumpkins

By Cindy Ott

By Cindy Ott
At this year’s Topsfield Fair in Massachusetts, Ron Wallace broke the world record for the biggest pumpkin yet with a specimen weighing in at 2009 pounds. Photographs of Wallace next to this colossal body of orange flesh made headlines not only in the regional Boston Globe but also the nationwide Huffington Post. Yet every year in the popular press scenes of a pickup truck with its bed filled to the brim or a grown adult comfortably nestled inside a single giant pumpkin document the variety’s comically huge size.

Is Almanac Day in your calendar?

By Benjamin Wardhaugh
As well as Halloween, Guy Fawkes, and All Saints’s day, this time of the year used to see another day of fun and frenzy. ‘Almanack Day’, towards the end of November, saw the next year’s almanacs go on sale. It generally came round on or about 22 November: St Cecilia’s Day. In London, Stationers’ Hall would be crammed to the rafters…

Drugs in the Internet era

By Les Iversen
When Drugs: A Very Short Introduction was published in 2001, drugs were relatively hard to obtain. Recreational users could buy illegal drugs from back-street dealers, while prescription medicines required a trip to the doctor to obtain a script. The Internet has changed all that. Nowadays in Western Europe and in North America there are dozens of website dealers offering novel psychoactive drugs (“legal highs”) and prescription medicines at modest prices. The market for designer drugs has grown hugely.

Should fishing communities play a greater role in managing fisheries?

By Robert Deacon
Marine fisheries around the world are in a state of decline. Each decade the U.N. Food and Agriculture Organization reports that a larger fraction of the world’s fisheries are overexploited or depleted. Historical trends in individual fisheries have led some scientists to predict all major fisheries will be collapsed by mid-century. The economic status of these resources is even more dismal.

In praise of the podcast

PB. The initials are not exactly as familiar as, say, BBC, or NPR, but we’re not operating in a massively different environment. PB: Philosophy Bites. Time was when to broadcast on the radio (or the ‘wireless’) you’d have to seek a license for permission to use a teeny weeny portion of the radio frequency spectrum. Broadcasting was time-consuming, bureaucratic, and above all expensive. It required staff and costly equipment and it was possible only with the support of highly-trained studio technicians and engineers. No longer
