The Royal Bank of Scotland has donated a state-of-the-art three dimensional CT scanner to an Edinburgh hospital, but with strings attached. The scanner will be available for use by NHS patients, but the Bank wants its staff to have priority access to up to 25% of the scanner’s capacity.
Some politicians and academics are opposed to the gift. But would there be good grounds for rejecting it?
Not a day
seems to pass without some news on the possible catastrophic impacts of climate
change. International politics aims at establishing binding regulations for
greenhouse gas emissions – but quite rightly gets accused of only paying lip
service (though at least last weeks agreement of the G8
states to reduce greenhouse gas emissions might yield the right direction).
However, implementation of these emission cuts is up to the individual states –
but whichever step a government undertakes, there seems to turn up an interest
group that is heavily opposed. The UK’s proposed system of personal carbon
credits suffers exactly this fate.
Monday, the environmental audit committee urged the government to lead the way
in allocating individuals an allowance of marketable carbon credits. Under this
scheme, people would be given an annual carbon limit for fuel and energy uses.
This limit could be exceeded by buying credits from those who use less. Apart
form being accused as “costly,
bureaucratic, intrusive and unworkable”, criticism was also raised as this personal
carbon credit scheme might be unfair – just as, for example, a taxation
approach to reduce carbon dioxide emissions would be unfair as well. Some
people might have good reason for using more fuel than others as they live in
the countryside, drive their old neighbour to the supermarket, etc.

Earlier this month Greenpeace released a report entitled ‘False Hope’ attacking carbon capture and storage (CCS) on the grounds that it ‘wont save the climate’ and that it therefore presents us with a false hope. (See: http://www.greenpeace.org/international/press/reports/false-hope ). Greenpeace argue that we should abandon attempts to develop CCS technology and that we should devote our efforts to reducing energy demand and developing solar, wind and wave power instead. It seems very odd that an organisation that devotes itself to saving the planet should spend its time trying to attack an emerging form of technology that is being developed to help reduce carbon emissions especially at a time when, as Greenpeace are quick to stress, the carbon we emit is causing environmental damage to the planet – damage that may be irreversible.

The vote by the British parliament to keep the upper legal limit on abortion at 24 weeks was headline news around the world. An article in The Economist (1) considers that the British were spared America’s abortion wars partly because Britain is less religious than America, but also because abortion laws are made in Parliament, where shades of grey can be debated, not in the courts, where black or white usually prevails.
Interestingly much of the debate was about ‘viability’ – the minimum gestational age at which a newborn is said to be capable of surviving with modern intensive care facilities. This is a simple across-the-board week count. But the survival rate of newborns also depends on many other factors, including where they are born (2, 3), fetal health including the presence or absence of an abnormality (which remains lawful where the child will be ‘seriously handicapped’), plus the condition of the newborn. While around half or so of 24 week newborns in Britain may survive, many or most of the abortions at around that gestation are of problem, or unhealthy, pregnancies.

Jim Todd reports about his measles experience at BBC News. A number of years back such a report about how a case of adult measles feels would have been absurd, since so many had suffered it. A few years back it would have been absurd because measles was rare thanks to vaccination. But now, due to a reduction in vaccinations, the risk of measles is rising. Health chiefs in London are stepping up the vaccination program to try to stave off the rising number of cases. The key problem is that in many areas of London only 62% of toddlers
have been immunised, compared to the 95% that is needed to achieve herd immunity.
Vaccinated people act as firebreaks: if enough people are immune to a
disease long chains of infection become improbable, and epidemics do
not occur. Given this, should measles vaccination be compulsory?

A report by the Academy of Medical Sciences looking at different aspects of drug use and mental health has identified a growing trend for off-label use of drugs intended for the treatment of diseases including narcolepsy, ADHD and Alzheimer’s. The use of such drugs by a healthy individual can improve memory, alertness and concentration. While the report does not condemn the practice, it raises a number of potential concerns over safety, and fairness. Professor Les Iversen, report co-author, highlighted concerns that the use of enhancement in exams would unfairly advantage wealthier students, and suggested that the use of such drugs could be considered cheating. The report recommends that legislation is prepared to tackle the misuse of such drugs, including the potential for urine testing in schools and universities.
Below are responses from Julian Savulescu, Nick Bostrom, Anders Sandberg and Mark Sheehan on the effects of cognitive enhancing drugs, and the issue of cheating

MPs voted on Tuesday on two of the most controversial issues surrounding reproduction- the provision of IVF treatment, and the availability of legal abortion. Under the new laws, IVF clinics will no longer have a legal requirement to consider the need for a father, but will instead be asked to ensure provision of ‘supportive parenting’, removing any barrier to single women and lesbian couples conceiving through the treatment. In a separate amendment, MPs were asked to consider the legal time limit on abortion, which currently stands at 24 weeks. Given the option to reduce this limit to 22, 20 or even just 12 weeks, MPs voted by a comfortable majority to stick with the status quo.
The UK is now at the forefront of rational reform to legislation governing reproduction and research. The Human Fertilisation and Embryology Bill has now approved the creation of human admixed embryos, with important implications for scientific advance.

Carbon nanotubes are tiny man-made fibers with an incredibly high tensile strength. They are one of the most promising nanotechnological developments with many potential applications in electronics, medicine and futuristic materials. However, a new study by a group of scientists from the US and the UK suggests that carbon nanotubes may cause health problems similar to those of asbestos. The problem comes from their similar shapes: both nanotubes and asbestos consist of hard microscopic fibers that can cause significant damage to the lining of the lungs. The study involved exposing mice to nanotubes and found that nanotubes of a certain size caused asbestos-like inflammations and lesions.
Scientists in the US recently created a fluorescent human embryo. This was achieved by inserting a gene for green fluorescent protein. This shows that it is possible to successfully transfer a gene from a non-human animal to a human and for that gene to express its function. Other animal studies have shown that such gene transfer is both safe and effective, creating super animals, such as mice with colour-vision derived from human genes transferred.

Two attempts to amend the Human Fertilisation and Embryology Bill’s provision to allow ‘saviour siblings’ failed in the House of Commons yesterday. The first attempt was to block the practice and failed 342 to 163. The second attempt was to limit the provision to life-threatening cases. It was defeated 318 to 149. As it stands the Bill allows embryo testing and hence selection for ‘saviour siblings’ provided that “there is a significant risk that a person [the sibling ‘to be saved’] … will have or develop a serious physical or mental disability, serious illness or any other serious medical condition.”
