Sounds green to me
Ultrasound - sound at frequencies greater than 20kHz - although inaudible to our ears, is useful. Bats and ships use it for navigation, obstetricians take pictures of the unborn foetus specifically with the harmless high-frequency waves beyond 2MHz.
A particulate problem
The bad news about particulate matter keeps flowing, while adverse health effects are even being felt at relatively low pollution levels.
Chemical footprint
Most of us should by now be aware of carbon footprinting, calculating the amount of carbon dioxide released into the atmosphere as a result of the activities of a particular individual, organisation, or community, and therefore focused on energy consumption and efficiency, but a new US footprinting approach has turned its attention to chemicals.
Chemistry too complex for investors
Chemists need to be better at talking to investors. They need to build a better business case that demonstrates the impact of their proposed research - in a language that investors can understand.
Queen bee stress
Colony-founding queen bees are 26% less likely to initiate a colony after exposure to the neonicotinoid thiamethoxam. Mathematical modelling shows that this leads to a 28% increase in the likelihood of population extinction, according to researchers at Royal Holloway University of London.
A Strategy for life sciences
The UK government has pledged to invest £146m in leading edge healthcare technologies to support the country's life sciences sector. News of the investment came in late August, as Sir John Bell unveiled the results of an independent industry-led review of the UK life sciences sector.
Zinc battery boost
Australian researchers have found a solution for one of the biggest stumbling blocks preventing zinc-air batteries from overtaking conventional lithium-ion batteries as the power source of choice in electronic devices.
Digital revolution
Digital health could enable people to access prevention and curative services cheaply and conveniently.
Nanobeads to save coral reefs
Coral reefs are the world's most diverse ecosystems, yet they could be in danger of disappearing altogether in the next few decades. Rising temperatures are a big part of the problem, but so too it seems is a common ingredient of sunblock.
