New thinking needed on student debt

Jonathan Wolff suggests creative thinking from HM Treasury to resolve the impending crisis of student debt. Although most will be working hard to help fund their studies - perhaps there are one or two economics students with a bit of spare time and imagination who can design a better model for the long term financing of higher education.  They may not even need the promise of a knighthood - just a sporting chance of a system that does not penalise them through future marginal tax rates. That would be a breath of fresh air.

Good progress but more to do to tackle diarrhoeal disease

According to a recent paper in the Lancet infectious diseases there has been a lot of progress made in reducing the global burden of diarrhoeal disease, with an overall reduction in mortality of 20% between 2005 and 2015.
But despite this great progress, we should not forget that in 2015 alone 1.3 million people died from diarrhoeal diseases.  And around 500,000 of those were children.
Rotavirus is the biggest contributor to deaths - and at Wellcome we are pleased to be working with Merck to support the Hilleman Labs - a vaccine R & D facility in New Delhi - which is making great strides in developing an affordable and stable vaccine for Rotavirus.
One of the other major contributors to childhood deaths is Cryptosporidiosis which  affects babies and young children, and people with low immunity, such as HIV or transplant patients. There have been many challenges in working with this parasite, which has meant that developing improved treatments has been particularly difficult.
So it was fantastic to see the recent paper in Nature from a group of researchers from the Novartis Institute for Tropical Diseases (NITD); University of Georgia and Washington State University describing their development of a new  new small molecule drug candidate. 
In this study, the research team have established a drug discovery process which has led to the identification of new inhibitors of Cryptosporidium lipid kinase PI(4)K (phosphatidylinositol-4-OH kinase). The study used phenotypic assays and screened 6,200 compounds to identify pyrazolopyridines as new potential candidates. Studies show resolution of diarrhoea in model systems - and further work is ongoing to further evaluate these compounds for development as new treatments.
The Innovations team at Wellcome was proud to have been part of the group of organisations that supported the study.

Harry Kroto - The Interstellar Chemist

I first met Harry in summer of 1993 - when my research group visited the Department of Chemistry (MOLS) at Sussex in advance of our relocation in October. Having tea by the lilly pond I was overwhelmed to be joining an extraordinary group of distinguished faculty. They were all incredibly friendly - and remarkably tanned and fit - due in part to regular (and competitive) lunchtime tennis matches.

Harry introduced himself, trademark sunglasses and smile - gently quizzing me about my research programme. We did not have much in common scientifically - but he was supportive of young people - and genuinely excited by all aspects of chemistry.

As time went by, we got to know each other - mainly because we used to bump into each other in the department (or the car park) at the weekend. But also from time to time - chatting about chemistry over tea or in his chaotic office.. 

He would have often been globe trotting during the week - giving lectures to large audiences on the discovery of buckyballs. But despite his great success as a researcher, Harry was committed to students and to being a part of the life of a University Department.

Harry loved giving spectroscopy lectures to the first year students…and he regularly gave research seminars - this despite the fact he was “on the road” seemingly continually - enthusing about buckyballs and nanotechnology. 

He cut a dash as a speaker - and was incredibly charismatic. He combined excitement, wonder and energy whenever he spoke about science, maths, art, the footballer Rodney Marsh, Richard Feynman, music, Sussex or a recent design he’d worked on. He had one speed in life - fast.

I remember him giving the most extraordinary research lecture on chemistry and interstellar space - not primarily about C60 - but rather fundamental spectroscopic studies…it was great work with the potential to offer insight into molecular origins of life. I recall a discussion about the origin of amino acids (celestial molecules or not?) and I did ask him if he somewhat regretted getting “diverted” by the discovery of C60…he just smiled!

In 1996 Harry (along with Curl and Smalley)  received the Nobel Prize for the discovery of fullerenes. It was the only time I ever saw him speechless - and somewhat dazed. The following day we had a reception in the Department - all the students and staff - by the pond - Kroto being congratulated by one of his “heroes” Kappa (Sir John Cornforth).  

In the 1990’s, nanotechnology was still very nascent - and the discovery of fullerenes was a watershed moment for nanoscience and perhaps for chemistry as a whole.

Despite his great successes Harry remained down to earth. Always a great believer in the skill and flair of individuals - he took great interest in people in the Department. He also enjoyed parties - I remember him coming to our house in Lewes for one. It was a glorious sunny day and it was packed with students and staff - we were drinking Harveys and red wine…some of us suggested creating a 6ft sculpture of a buckyball (diamond or graphite!) - to be entitled - Harry’s ball..he was never convinced..

Harry was also passionate about education and public engagement and the Vega Trust contains some unique footage of many of the science greats. Vega never seemed to quite take off as I thought it should - but maybe he was too far ahead of his time - or perhaps trying to do to many things at once.

Harry and I both left Sussex around the same time - him to join Florida State University. We happened to meet at another party in Brighton the day following his formal departure from Sussex - after 37 years on the faculty. I think the sunglasses were hiding the tears. 

We kept in touch from time to time - mainly by email - and I went over to see him at his Sussex home in his beloved Kingston.  We talked for some hours and he played his Martin..that was perhaps the last time I saw him..

Harry was part of a cluster of great chemists in the late 20th century at Sussex. Many have sadly died including Eaborn, Lappert, Murrell and Cornforth. These modern day explorers of the periodic table had a huge impact on organic & inorganic synthesis, polymer and materials science and chemical biology. They were rigorous, curious researchers - but each with a spirit of humanity, collegiality, warmth, good humour and humility - the epitome of a great faculty.  

Harry was a star that shone brightly - even amongst those stars. A creative academic researcher, an exceptional teacher, a committed scholar and a charismatic communicator. 

Harry - it was a pleasure to know you - you taught us a lot.

Britain needs talent

Allister Heath highlights the importance of the international student market to the UK economy. But the talent that comes into our universities from overseas is worth much more than just a short term cash injection. 

Many overseas students coming to the UK, are some of the worlds most talented, and offer an extraordinary benefit to our society and economy. They have the capacity to help UK businesses understand how to penetrate overseas markets and, as the London First study highlighted, these future leaders are more likely to do business in the UK as a result of studying here. We should also not forget that the Britain's global position in research is a consequence of being able to get the very best postgraduate students, postdoctoral researchers and professors from across the globe. Many go on to make remarkable contributions to our knowledge economy, through teaching, research, and by creating new companies and winning Nobel prizes. 

In todays competition for the brightest minds, it is vital that the UK continues to be a destination of choice for the most promising young talents, wherever they come from.  Mr Javid needs to be allowed to get on with his job and make it unambiguously clear, that Britain welcomes smart people from across the world,  and is serious about, and open for, international business.
