Sex in the future

Human sexuality is a biological drive as well as a cultural phenomenon, the future will see advances in both. It is likely that there will be more same-sex relations as boundaries of gender blur. We are experiencing the first waves of the androgynous look in couture fashion as well as the urban metrosexual male, and as long as there is no total religious takeover of our culture, it is likely that more people will have gay sex without necessarily identifying as gay.

Non-reproductive sex seems to always have been a part of the human sexual repertoire and the entertainment industry knows how to take advantage of this. Whenever a new technology arrives you can be sure that if it can be adapted to sexual uses. Painting, photography, film, and even pottery have been utilised in pornography, while the VCR and the camcorder gave us cheap porn.

Tomorrow's workplace will be your home, giving you less opportunities to flirt with co-workers in person. Internet pornography and cybersex will be the alternatives. New sex toys enabling something called multimedia masturbation as well as research developments in areas of virtual reality and holographic imaging all leave little to the imagination. Perhaps you want to know exactly how your partner feels during orgasm. Well, biotechnology will be there to assist, leaving nowhere for those orgasm fakers to hide.

Psychotropic drugs have of course been used for millennia in the form of aphrodisiacs. But given that the world's population is ageing and many of us will live to be 100, there should be big money to be made in the field of eroto-gerontology - Viagra being the first step in this direction. Synthetic oxytocin, the so-called "bonding chemical", has already been produced, possibly paving the way for the ultimate relationship quick-fix.

However, all this technicising of sex begs many questions. Will it lead to an even more socially inept society? Will it force us to redefine infidelity? Will we still appreciate sex as something sacred, or will it just be fun and games? What do you think?

A malarial dream

A group of chemical engineers at Bath University are part of a research and business consortium to have won a £500,000 grant to aid the worldwide effort in combating the spread of malaria. The research team, led by Dr Alexei Lapkin from the University's Department of Chemical Engineering was originally commissioned (in 2005) by the non-profit Medicines for Malaria Venture (MMV) and the Dutch Government to evaluate a range of new technologies. The aim was to find ways in which large-scale production of malaria medication could be made cheaper and environmentally friendly.
These investigations led the team to discover innovative ways in which artemisinin-based combination therapies (ACTs) can be produced.

Malaria is currently affecting around 300-500 million people worldwide, killing more than 1 million people - predominately children. Yet, it is an epidemic that goes mostly unnoticed, perhaps because it is occurs at comfortable distance, being most common in Africa, Asia and Latin America.

The illness is transmitted from infected to uninfected humans through the bite of an infected female Anopheles mosquito.

Global campaigns to eradicate malaria have been in place since the 1950s, but attempts have been mostly unsuccessful and the number of people dying from the disease is now higher than it was 30 years ago. This has mostly been due to high levels of resistance to drugs.

The realisation that new strategies are needed to combat the increase in malaria cases involved looking beyond traditional Western medicine. Artemisinin (also known as qing hao, sweet Annie and sweet wormwood), a herb used in traditional Chinese medicine for over 2000 years, was finally accepted by western scientists in 2004. It was a large internationally run trial which led to the breakthrough of the anti-malarial. The trial showed that artesunate, derived from the Chinese herb, could cut malaria death by over a third.

However, artesunate and other ACTs are currently dangerous and expensive to produce, as well as being harmful to the environment. It is in the extraction process of the raw materials that the Bath team is leading the way for the future. Dr. Lapkin says "Our focus is on driving down the cost of extraction to help make this 'wonder drug' more readily available to the people who need it".
