What are the opportunities for us and our community? Although many of these goals have not yet been reached, they have provided an unprecedented impetus for dialogue and subsequent actio… The solutions that they can generate, and the levels of access that they can enable, will be crucial to our vision for the world beyond 2015.” Ban Ki-moon, UN Secretary-General (December 2014) At the beginning of the 21st century, the UN set its Millennium Development Goals with an original target of 2015. Some are using the tailored pores of metal–organic frameworks (MOFs) to grab carbon dioxide molecules, while others are incorporating it into minerals used in building materials. ‎Global Challenges/Chemistry Solutions is a series of podcasts describing some of the 21st Century’s most daunting problems, and how cutting-edge research in chemistry matters in the quest for solutions. We use cookies to support your experience on our website. 162 0 obj <>stream About 2–5% of the cytosine bases within a genome have been altered by DNA methyltransferase, creating a new base called 5-methylcytosine that tends to reduce the expression of the genes it appears in. Although these marks are largely stripped away as embryos form, some can persist – including those that confer longevity or increase disease risks, according to animal studies. Take histone proteins, for example: these biological bobbins wind up the DNA double helix to pack it into chromatin, the building blocks of chromosomes. There are literally hundreds of thousands of ways that a protein can fold. In the longer term, roll-to-roll processing could enable organic photovoltaics or dye-sensitised solar cells to be made at even lower costs than silicon modules. It is already used to make urea and salicylic acid, and in 2011 an Icelandic company called Carbon Recycling International started to use geothermal energy to convert the gas into methanol, producing around 2 million litres per year. Knowledge Hub For the last couple of months we have been developing a new knowledge sharing section. “… if we continue on our current path, by 2050 between $66-106 Bn worth of coastal property in the US will likely be below sea level, with $238-507 Bn worth of property below sea level by 2100.”. American Chemical Society (ACS) moved forward with Global Challenges/Chemistry Solutions. These reactions should run sequentially, under continuous flow conditions, speeded by efficient catalysts.

Researchers involved in CO2Chem are looking for cheap, robust catalysts, based on iron or aluminium, for example. ‘The solid form of a chemical has very different properties depending on its crystal structure,’ explains the CCDC’s David Bardwell, who coordinates the tests. Just over a decade later, the Cambridge Crystallographic Data Centre (CCDC) launched the first of its crystal structure prediction ‘blind tests’ to stimulate progress towards Maddox’s goal. ‘That can be quite a problem for the pharmaceutical industry.’ Different crystal polymorphs have different solubilities, for example, which can affect how a drug is absorbed by the body or complicate manufacturing processes. Battery storage is still incredibly expensive. Summary: Taking inspiration from trees, scientists have developed a battery made from a sliver of wood coated with tin that shows promise for becoming a tiny, long-lasting, efficient and environmentally friendly energy source. h�b``0f``������� *`b�d1c(f`�fd�ٰ�ASAҀρ} �c8�qO���� �[JևL `���!

Some may be conquered in a decade; others seem like distant dreams. Deirdre Black, Royal Society of Chemistry. It’s not quite a Star Trek replicator, but is automated synthesis as much of a fantasy? Meanwhile, the Human Epigenome Project is currently trying to map the locations of all possible epigenetic changes across the whole genome. You’ll hear the stories and meet the scientists whose discoveries are helping to make life longer, healthier, and happier for millions of people. ‘We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organise and measure the best of our energies and skills.’ President Kennedy’s 1962 clarion call for the Apollo programme set out a breathtaking vision that mobilised the biggest scientific and technological effort in history. In the late 1990s, he and his colleagues began to develop a new method of sequencing DNA – working out the precise order of the cytosine (C), guanine (G), adenine (A) and thymine (T) nucleobases that encode information in our genomes.
