The Great Botox Experiment in Mood Enhancement

by Guy Kahane
November 7, 2008

Suppose that the people around repeatedly smile or shake their heads. Although you may not notice it, it is very likely that soon you too will begin to smile or shake your heard. And it is likely that this will affect how you feel and what you think. Or at least this is what social psychology tells us.

In one experiment that demonstrated this ‘chameleon effect’, subjects were recorded unconsciously imitating the movements of an experimenter. In another experiment, when subjects contorted their faces in a way that paralleled smiling, they felt happier. And when subjects were told to engage in tasks that required them to move their heads as if they nodding or shaking it, this affected how easy it was to persuade them of something—it was easier to persuade them if they were nodding their head, harder if they were shaking it! (though only if the argument was good—see here for details.) What’s all this got to do with botox?

Top hats and top-ups: better health for the better off

The health secretary announced today that patients in the UK who choose to buy medicines not funded by the national health service, will no longer be excluded from receiving public health care. This announcement follows controversy about expensive cancer drugs that are available in other countries, but may not be available under the NHS.

Given that private healthcare is available in the UK (and overseas) for those who are able to pay for it, it seems unreasonable to punish patients who choose to spend their money on cancer drugs by denying them access to the public health system for part of their care.

Re-creating mammoths and the family dog: two different cases

by Alexandre Erler

The idea of reproductive cloning can easily be perceived as offensive, as a practice that constitutes the dark side of cloning and should be prohibited under all circumstances, by contrast with therapeutic cloning, the benefits of which are increasingly acknowledged. However, such reactions typically assume that it is human cloning we are talking about. Regardless of how we should assess this latter practice, it seems difficult to make a plausible case for a complete ban on reproductive cloning of nonhuman animals. On the contrary, such a technique appears to open up exciting prospects. A group of Japanese scientists, as recently reported in the press (by the BBC and the Guardian, among other sources) have thus managed to produce clones from dead mice that had been frozen for 16 years. According to the aforesaid scientists, this achievement raises the possibility of re-creating extinct species such as mammoths from their frozen remains – a bit like what happens in Steven Spielberg’s movie Jurassic Park.

Election ex machina: should voting machines be trusted?

by Anders Sandberg
November 3, 2008

When election of public officials through
public voting was instituted in the US,the framers of the constitution
had no inkling about how large the voting public would one day become. Beside logistical problems that
accidentally enfranchise goldfish and the many issues surrounding voter
registration a growing concern is the reliability of electronic voting
machines. As electronic voting machines are being installed, concerns about their reliability are being raised and legal battles ensue. In a Finnish election the system lost 2% of
all electronic votes. About 60% of American votes are cast on
paper ballots, but it might increase locally after problems with voting machines. The real fear is not that people might misvote due to misunderstandings or that votes might be miscounted, but that the machines themselves might be biased or easily tampered with. Can we trust the machines? Or are elections by their nature too messy for these problems to matter?

Should We Be Erasing Memories?

Scientists from the Medical College of Georgia in the US recently claimed to be able selectively to wipe out traumatic memories. These scientists experimented with mice and found that a particular protein plays a crucial role in the formation of memories. When they made the mice produce an excess of this protein, memories of painful events were completely eliminated. Such research raises hope for treating conditions such as post-traumatic stress disorder (PTSD), in which painful memories become intrusive and damage an individual’s ability to live an ordinary life. In theory, such memories could either have their emotional strength reduced or be blotted out altogether. In practice we are still some distance away from being able to achieve this, but it does not seem unreasonable to think that within the next decade we will be able to control the erasing of memory.

From doomed lamb to potential phoenix – the story of a modern sacrifice

by Barbro Bjorkman

‘Is there a place for sacrifice in the modern world?’ a colleague asked during a conference in Oxford this weekend. To an extent the answer appears to depend on what we mean by sacrifice. The traditional religious version is arguably in demise in a secular and increasingly individualistic society, but could it be that another version is on the rise? It has become almost standard procedure that when a politician, business leader or other public person is caught doing something they really shouldn’t do, they go for the public apology. In this grovelling mea culpa parade they offer themselves up in tasty little morsels intended to satisfy the public appetite. Sometimes the outrage is such that, for all their efforts, they are still sent packing. Yet all is not lost, after a while out in the cold a surprising number resurface to take on new posts involving big responsibilities presumably requiring both a strong character and sound judgement. But do we really have good reason to think that time out of the lime light equals time spent on moral contemplation?
