No chemistry textbook, classroom, auditorium, or research laboratory is complete without a copy of the periodic table of the elements. Since the earliest days of chemistry, attempts have been made to arrange the known elements in ways that revealed similarities between them. However, it required the ...

An extraordinary synthesis of this simple-looking guaiane natural product (along with it’s exo-methylene analogue, pleocarpenene), Marc Snapper has once again used deft control of pericyclic reactions to produce some extremely odd looking intermediates in this synthesis. As regular readers will know ...

Ah, back in to Nature for another nibble at organic synthesis for the biologists, and some slightly-odd looking structures. It took me rather a while to get used to COOMe rather than CO 2Me… However, one thing guaranteed with chemistry in Nature is quality, and it certainly shows in Trost’s latest w ...

Medium rings are a beguiling feature found in a host of natural products, owing to their behavioural oddities. While the properties and synthesis of smaller rings (three to six atoms in size) are well known, and that of true macrocycles can at least be estimated, each medium ring has its own persona ...

Chinese researchers have developed a method for delivering nanoparticles to a specific site of action using temperature-triggered squirting. Nanoparticles are becoming more widespread for disease diagnosis and therapy but protecting them from degradation and delivering them to target tissue is still ...

In looking for potential uses for highly water-repellent, superhydrophobic materials, scientists have mainly focused on obvious applications such as water-proof clothing and self-cleaning surfaces. But now US scientists have a new idea: using them to deliver drugs. It turns out that superhydrophobic ...

Pesticides could be suppressing people's vitamin D levels, leading to deficiency and disease, say scientists. The warning follows the discovery that adults with high serum concentrations of organochlorine pesticides such as DDT have lower vitamin D levels. Exposure to lose doses of organochlorine pe ...

Fragranced household products, even those labelled as 'green', can emit large numbers of hazardous chemicals that aren't listed on their labels, US researchers have confirmed. The research raises questions about the risks associated with these products and regulating the claims on their labels. A te ...
