March 21, 2010 Women in science: Pioneers blaze path for others By Rachel Shields The Royal Society has named its top 10 female scientists, yet many still feel marginalised

They have mapped the infinity of space, developed spray-on skin for burns victims, pioneered cancer-beating therapies, created cutting-edge computer chips, discovered the first radio pulsars, and won Nobel prizes. But female science professors are still being asked to make the tea and take notes at meetings by their - often junior - male colleagues. Sexism remains all too prevalent in Britain's scientific community, according to some of its leading figures, even as The Royal Society unveils a list of the 10 greatest women scientists in British history. Women scientists this weekend called for government funding to be ring-fenced for projects headed by women, and men who are principal child carers, to help them get ahead in what remains a male-dominated profession. "If you are on high-level committees, you'll be asked to make the tea," said Professor Athene Donald, the deputy head of physics at Cambridge University. "Recently, on a committee, the chairman thought I was the secretary. And I've been in committees where we've been addressed as "gentlemen", despite the fact that there are women there. It is very off-putting."

Baroness Greenfield, who is suing the Royal Institution after it ousted her as its director in January, has criticised the Government for failing to provide enough financial support for women trying to make a career in the sector. "However much people support and encourage women, it has got to be backed by resources. The Government has never really delivered that," said Lady Greenfield. "I hope that the election campaign addresses this. What is needed is about £50,000 a year per woman, and then add the cost of equipment, and you are looking at £200,000 for one person. Science research is expensive." Lady Greenfield also argues that the insecure nature of science research puts women at a disadvantage: most scientists have to make do with temporary research contracts until they secure a fixed position in their thirties and forties; maternity leave provision is limited; and, for those in cutting-edge research, a career break at that stage can leave them way behind their male peers. "Many people won't have security of tenure until they are in their thirties. It is one of the few employment cultures with no security," she said.

It is thought that the subject's "nerdy" image puts girls off studying science beyond GCSE, and the sector also struggles to retain female graduates, with more than 70 per cent of women science graduates deciding on non-science related careers. One of the aims of the Government's 10-year strategy on science and technology, launched in 2004, was to encourage more women into the sectors. "The science and technology professions have been built by men, for men," said Annette Williams, the director of the UK Resource Centre for Women in Science, Engineering and Technology. The centre was established in 2004 to address the gender imbalance by using mentoring, training and networking. "Often, women can find the climate quite hostile. And science and technology are so male-dominated that they are behind other sectors in terms of things like flexible working," said Ms Williams.

The Royal Society, which did not allow female fellows to join until 1945, is using its 350th anniversary year to highlight the work of women scientists, such as Rosalind Franklin, whose work on DNA led directly to the discovery of the structure of the DNA molecule, and Dorothy Hodgkin, a Nobel prize-winner for chemistry. Despite the negative experiences of many female scientists, some believe that the situation is improving. "The number of women science professors rose from 8 per cent of the total in 2004 to 11 per cent now. I think we had something to do with that," said Ms Williams. While women may be under-represented in science, few are in favour of "quotas" of jobs being reserved for women. "Affirmative action can be very damaging. Women don't want to be appointed because they are women, they want to be appointed because they are good," said Professor Donald. "But if you advertise a job, you should have a proper search, and encourage women to come forward, not just appoint someone you know."

The Royal Society Top 10

1. Caroline Herschel (1750-1848)

As an assistant to her brother, a royal astronomer, Herschel discovered eight comets and catalogued star clusters. She was the first woman scientist to receive a salary and was awarded many honours.



2. Mary Somerville (1780-1872)

The Scottish scientist was only the second woman to receive recognition in the UK for her scientific experiments, which were on magnetism. Her popular renditions of the French astronomer Laplace's book Traité de Mécanique Céleste made her famous.



3. Mary Anning (1799-1847)

The daughter of poor Dis- senters, the palaeontologist made a number of important finds in Lyme Regis, including the first correctly identified ichthyosaur skeleton and the first two plesiosaur skeletons ever found. She also discovered important fish fossils.



4. Elizabeth Garrett Anderson (1836-1917)

Denied entry to medical school, Garrett Anderson instead passed the Society of Apothecaries examination to become the first English female doctor. She founded the New Hospital for Women in London and was influential in the passing of an Act permitting women to enter the medical profession in 1876.



5. Hertha Ayrton (1854-1923)

Working with her husband, Professor William Ayrton, Ayrton published several papers on the electric arc. In 1902 she became the first woman to be nominated as a fellow of the Royal Society, although as a married woman she could not accept.



6. Kathleen Lonsdale (1903-1971)

A pioneer of X-ray crystallography - the study of molecule shapes - in 1945 she and Marjory Stephenson were the first women to be admitted as fellows to the Royal Society. She was the first female professor at University College London, and the first woman to be president of the British Association for the Advancement of Science.



7. Elsie Widdowson (1908-2000)

Her work with Professor R A McCance revolutionised the way the world assessed nutritional values and how mammalian development was perceived. She worked on nutritional problems during the Second World War, and on treating the effects of starvation suffered by concentration camp victims.



8. Dorothy Hodgkin (1910-1994)

Hodgkin discovered the structure of penicillin and of vitamin B12. She was awarded the Nobel prize for her work, and was made a member of the Order of Merit. She devoted much of her later life to championing scientists in developing countries.



9. Rosalind Franklin (1920-1958)

Her work on the X-ray diffraction images of DNA was used to formulate Crick and Watson's 1953 hypothesis of the structure of DNA. She led the pioneering work on the tobacco mosaic and polio viruses.



10. Anne McLaren (1927-2007)

McLaren produced the first litter of mice grown from eggs that had been developed in tissue culture and transferred to a surrogate mother, paving the way for human in vitro fertilisation.



Today's Trail Blazers

1. Susan Greenfield Professor of pharmacology, University of Oxford

"People don't sell science to young people, and especially to girls, as well as they might. It takes time and resources to send people into schools. Doing that sort of thing is regarded very badly in the scientific community, it is seen as 'dumbing down'."



2. Patricia Fara Director of studies, history and philosophy of science, Cambridge University

"Younger women believe there is no discrimination against women in science, but I think that is optimistic. Women are squeezed out of exciting research projects. It certainly isn't a level playing field, you just have to look at the statistics. It is tough for women."



3. Julia Higgins Professor of polymer science, Imperial College London

"Even now women in science are rather invisible. It is a cultural thing. When people talk about Newton and Darwin, we want them to remember the women who did amazing things, too."



4. Uta Frith Emeritus professor of cognitive development, University of London

"We still have a long way to go. Women had a late start in the profession. I'm privileged to be one of the few women recognised in science, but there are so many talented women who will do great things."



5. Sunetra Gupta Professor of theoretical epidemiology, Oxford University

"It is only since I undertook to write a children's book on women scientists that I have come to know their lives in any detail - which is embarrassing, but also makes me realise how much of a need there is for the book."



6. Maggie Aderin-Pocock Royal Society university research fellow and a space scientist for Astrium Ltd

"My career has been great up until now, but I'm due to give birth to my first child in three weeks time, so that might pose more of a problem. Career breaks are a problem in science, as you aren't keeping up with the cutting-edge research."



7. Athene Donald Deputy head, department of physics, Cambridge University

"There is an unconscious bias. The number of women science professors is only about 11 per cent. It is improving, pathetically slowly. I think the Royal Society is working really hard over the gender issue. That they put their hands up and say 'mea culpa' is a positive message."



8. Helen Mason Solar physicist, Cambridge University

"Research grants have been cut and universities are suffering financially; people are being made redundant. My fear is that the young women scientists will be hit hardest by this. Indeed, I know that this is happening, and I feel powerless to stop it."



9. Ottoline Leyser Professor of biology, University of York

"The list highlights how tremendously recent it has been that we've had the equality we are now enjoying, and how frustrating it is that things are not moving faster."



10. Nancy Rothwell MRC research professor, University of Manchester

"I'm often asked how I manage in a male dominated profession. I just don't recognise this description. I have experienced nothing but support from all my male colleagues."


Tech.view Mother of invention Aug 3rd 2007 From Economist.com Why is Japan the source of so many bright ideas?

WHEN it comes to being awarded patents, the Japanese are world champions. Japan has more than 1,200 patents per million people—more than twice as many as Switzerland, the next most prolific country (with 500 patents per million), and more than three times as many as third-ranking America (with 350 patents per million). Does that make Japan the most innovative country in the world? Difficult to say. But something rather exceptional is at work in Japan that encourages its scientists, engineers, workers and even housewives to seek fame and fortune by patenting their brainwaves. There’s a problem, of course, with using patents as an index of national performance. Patents are awarded for something that is novel, useful and non-obvious. As such, they measure success in discovering or inventing new things. They do not measure innovation, nor the economic activity that ensues. In the grand scheme of things, inventions are the easy part. Turning inventions or discoveries into innovations—ie, products and processes that enrich our lives or improve our well-being—is a vastly more demanding business.

Inventions and discoveries are made in the lab or on the kitchen table by a handful of individuals. By contrast, innovations absorb the energies and fortunes of large corporate teams and can take years to bring to fruition. An invention that cost $1,000 to conceive can easily cost $10m to turn into a successful innovation. Even so, with nothing better at hand, patents are often used as a proxy for innovation. And Japan’s high patenting performance says much about the country’s instincts for innovation. However, Japanese patents tell a mixed story. As noted in our “At a glance” feature on inventiveness, published on Economist.com on July 30th there’s a lot of multiple-counting in Japanese patent figures. The reasons are as much cultural as historical.

Although Japan is not a particularly litigious society, Japanese courts are more preoccupied with the letter than the spirit of the law, and can be extraordinarily pernickety when cases do go to trial. Until recently, when Japan’s patent standards began to converge with American and European ones, that forced Japanese patent examiners to adopt a far more atomistic view of what constitutes a patentable invention. Thus, were a bicycle to be patented in Japan, it could not be defined simply as a human-powered, two-wheeled vehicle, but would have to be considered as a family of patents covering the frame, wheels, crank, pedals, handlebars and saddle. But even after discounting for the Japan Patent Office’s multiple-counting, Japan still patents way over its weight. What was not mentioned in “At a glance” was that the Economist Intelligence Unit (EIU) white paper it was based on (which, in the interest of full disclosure, your columnist had a hand in writing) handicapped Japan by discarding one-third of its patents from the start. And still it came out top. Also left unsaid—and most intriguing of all—was that Japan achieves its stellar performance with rather mediocre inputs.

The EIU study created four indices for each of the 82 countries examined. Apart from the innovation index based on patents granted, two further indices ranked each country’s direct drivers of innovation (national research effort, education standards, technical skills, broadband penetration, etc) as well as those indirect environmental factors considered conducive for innovation (such as rule of law, tax regime, economic stability, labour flexibility and patent protection). Finally, an aggregate enabling index was created from a 70/30 weighting of the direct and indirect drivers. Despite having one of the best-educated workforces in the world, superb IT infrastructure, a well-oiled administration, good rule of law and protection of intellectual property, Japan ranks a lowly 14th in terms of its enablers for innovation. So, why does the country perform so well on the output side of the innovation equation, despite having such feeble drivers on the input side?

No one really knows. You can make educated guesses. The concentration of talent in manufacturing. The pursuit of excellence. The ferocious rivalry between Japan’s large electronics firms. The lingering relic of the country’s post-war catch-up mentality. Fears of economic isolation given the expansion of the European Union and the emergence of the North American Free-Trade Area. Anxiety about a rapidly ageing society facing a formidable pensions and health-care crisis.

All this may or may not play a part. But beyond the more obvious economic imperatives lie certain social factors that appear to be at work as well. In the early 1980s the Hakuhodo Institute of Life and Living (HILL) in Tokyo sought to capture the spirit of the times by looking at Japanese society through a prism of hitonami—a national tendency of wanting to be like others.

HILL argued that the old feudal habit of watching neighbours closely to see what behaviour the local war lord condoned or forbade had served modern society well. In particular, it helped explain why Japanese consumers had traditionally been quick to embrace new products. In certain ways, the customers were being even more innovative than the suppliers.



Back in Japan for his biannual pilgrimage, your columnist is beginning to feel that this tendency may explain much of the country’s natural talent for innovation. Certainly, coming up with bright ideas for future products involves a lot of informal and subjective “tacit” knowledge as well as documented “explicit” know-how. The accumulation and sharing of this tacit understanding (which is largely impossible to record) is what makes Japan tick. You only have to go into a Japanese pub in the evening to hear animated businessmen carrying on their after-hours office discussions. Perhaps it is the birru, jizake and shochu that are the real tonics for innovation.


US, EU, Japan fight China on rare earths

By Leslie Hook in Beijing, Joshua Chaffin in Brussels and Alan Beattie in Washington FINANCIAL TIMES Last updated: March 13, 2012 1:33 pm

The US, European Union and Japan have teamed up to bring a rare joint case at the World Trade Organisation against China over its export controls on rare earths.

US president Barack Obama was expected to announce the action later on Tuesday. But speaking in Brussels, Karel De Gucht, the EU trade commissioner, said Chinese restrictions on exporting the metals – 17 elements used to manufacture a wide range of items, from weapons to BlackBerrys – were hurting European manufacturers and “must be removed”.
