FeatureCrop protection chemicals
By 2030, the world's population is expected to rise to over eight billion - the need for safe and environmentally friendly crop protection chemical has never been greater

FeatureIda Noddack and the missing elements
Distinguished women chemists were rare in the early 20th century, but their contributions to chemistry are of great significance. Ida Noddack's scientific career centred around her intensive study of the Periodic Table, and resulted in her discovery, with husband Walter Noddack and physicist Otto Berg, of the metal rhenium, and of nuclear fission in the search for element 93.

The MoleAntimalarial drugs
Approximately one million people die annually from malaria worldwide. Tragically, 90 per cent of these deaths are among the under-fives in sub-Saharan Africa, who have little if any access to adequate healthcare. Drugs are used to treat the disease but parasitic resistance to these drugs is growing, so what is the alternative?

FeatureInvestigations get real
What real chemists do can be the basis of motivating investigations and learning in school chemistry
-
FeatureJesuits' powder and quinine
The powdered bark of the South American cinchona tree is the source of quinine - the mainstay treatment for malaria for centuries
-
FeatureMicrobial iron scavengers
Medicinal and analytical chemists take their cue from micro-organisms' ability to bind to iron in the design of new drugs and sensors

FeatureBetter than antibiotics?
Chemicals that make bacteria lose their hair could be a new weapon in the fight against infections, and at the same time help to overcome the problem of antibiotic resistance
-
FeatureDeadly things come in small packages
Painstaking work by chemists to characterise deadly alkaloids exuded in the skin of some brightly coloured poison arrow frogs has offered leads for new and useful pharmaceuticals
