Would you shock your brain to cope with culture shock?

Would you shock your brain to cope with culture shock?

In a paper published this last Friday, university of Oxford researchers showed that electrical stimulation may help people learn numbers faster (see Julian Savulescu’s post for Why Bioenhancement of Mathematical Ability Is Ethically Important). In the experiment, 20 min of stimulation to the right parietal lobe, a brain region shown previously to be important in numerical ability, caused subjects to faster learn the relative magnitudes ( i.e. which is bigger) of a set of nonsense symbols. Proper magnitude of each symbol was assigned beforehand by the experimenters.

When Cardiff University’s Christopher Chambers was reached for comment in the BBC article covering this paper, “he said that the study did not prove that the learning of maths skills was improved, just that the volunteers were better at linking arbitrary numbers and symbols and warned that the researchers needed to make sure other parts of the brain were unaffected.” Dr Chambers has an important cautionary point, but could learning the magnitudes of arbitrary symbols alone be beneficial? And how much would it matter if other brain areas were affected?

Death Aquatic

Can science tell us how chefs should treat lobsters? The Independent this week implies it can. It seems that this is important to diners who want reassurance that their dinner has not been killed in a “barbaric” manner.

Science may of course discover the quickest or easiest method of killing. Norwegian researchers in particular have dedicated significant time to this research. Of methods including ice, nitrogen gas, freezing, gradual or rapid heating, piercing of ganglia, salt baths and carbon dioxide gas, apparently electricity is best. A commercial product, “Crustastun” offers the ability to replicate this in the kitchen. However, the retail cost of £2,500, puts this out of the reach of all but the richest, most gadget obsessed or humanitarian seafood lovers. But there is a more basic question: do lobsters really feel pain?

Retaining privacy: the EU commission and the right to be forgotten

Do we have a right to be forgotten? That was the question posed to me by BBC Newsnight in the light of the EU Commission's latest draft framework for data protection policies. EU Commissioner for Justice Viviane Reding stated that “The protection of personal data is a fundamental right”, and set out to fix current privacy protection measures in the light of changing technology and globalization. Among other things users should be able to give informed consent to the use of their personal data, and have a "right to be forgotten" when their data is no longer needed or when they want their data deleted.

Why Bioenhancement of Mathematical Ability Is Ethically Important

by Julian Savulescu

In a paper just released today, Cohen Kadosh and colleagues (Cohen Kadosh et al., Modulating Neuronal Activity Produces Specific and Long-Lasting Changes in Numerical Competence, Current Biology (2010), doi:10.1016/j.cub.2010.10.007) described how they increased the numerical ability of normal people by applying an electrical current to a part of the skull. So what? Most of us don’t do that much maths after leaving school and manage just fine.

What is a pet worth?

by Russell Powell

Imagine that you leave your sprightly canine companion to the vet for a routine teeth cleaning, only to learn that due to spectacular negligence on the part of the veterinary staff, he was confused for another terminally ill dog and was accidentally ‘euthanized.’ Imagine another even more horrific scenario, in which a malevolent neighbor steals your feline friend and feeds her to his wood chipper, Fargo-style. For many owners who have extremely close relationships with their companion animals, these would be traumatic events of a life-altering nature. Unfortunately, in both scenarios there is little you could do about it, institutionally speaking.

Why god isn’t really a teapot.

by Lisa Furberg

Russell’s teapot is an analogy intended to refute the idea that the burden of proof lies upon the sceptic to disprove the existence of god. The argument roughly goes something like this: If I were to claim that there is a teapot revolving about the sun and then further suggest that because my claim cannot be disproved there is no reason to doubt it, then I should rightly be thought to be talking nonsense.
In line with Russell’s analogy, some atheists have “invented” more things in which belief seems just as ridiculous as that in a an orbiting teapot: a flying spaghetti monster, an invisible pink unicorn -to mention a few. This kind of criticism, often coming from people who are self purportedly “scientifically minded” seem to use variants of the original analogy into an argument that seem to have little resemblance to Russell’s original one. This new argument has considerably more “bite” to it, suggesting that belief in god is something of an absolute “no-no”: If you are a rational person who believes in the methods of science, the critics seem to say, you simply ought not believe in the existence of god (or gods) any more than you should believe in an orbiting teapot. So, does a belief in god transgress any of the principles of (good) science?

Could a ban on homebirth be justified?

Agnes Gereb, a midwife in Hungary, has been imprisoned for performing home births http://www.guardian.co.uk/world/2010/oct/22/hungary-midwife-agnes-gereb-home-birth. She faces various charges, including negligent malpractice and manslaughter (relating to a homebirth in which the baby died after a difficult labour). While home birth is theoretically legal in Hungary, in practice independent Hungarian midwives are not certified as being able to ensure safe conditions for home birth.

Media commentary in this country has on the whole been very sympathetic towards Gereb (for example http://www.bbc.co.uk/programmes/b00vhfg2), implying that the rules which prevent women from giving birth at home are unwarranted restrictions on their freedom. Although in most developed countries home births are the exception rather than the rule, they are generally felt to be something women have a right to choose to have. A plausible reason for this is that birth is seen as a very important, as well as personal, experience which the mother should have control over. Is Hungary justified in challenging the existence of such a right?

Inviting invasion: deep space advertisments and planetary security

The Register warns that Dixons risks future of humanity with Star Wars-themed ads: the electronics chain, not satisfied with merely human customers also as a publicity stunt broadcast its ads into deep space, presumably for aliens to receive. This is done using the firm Deep Space Communications Network, who offers to beam messages into space using their satellite dish. Earlier this year an invitation to the Klingon opera 'u' was beamed towards Arcturus using a Dutch radio telescope. Are these stunts putting mankind at risk?
