A combination of agrochemicals shortens the life of bees, study shows

A new study by Brazilian biologists suggests that the effect of pesticides on bees could be worse than previously thought. Even when used at a level considered nonlethal, an insecticide curtailed the lives of bees by up to ...

Antibiotics found in some of the world's rivers exceed 'safe' levels, global study finds

Concentrations of antibiotics found in some of the world's rivers exceed 'safe' levels by up to 300 times, the first ever global study has discovered.

Artificial receptor distinguishes between male and female hormones

Chemists at Tokyo Tech's Laboratory for Chemistry and Life Science have designed and developed a capsule-shaped synthetic receptor that can distinguish between male and female steroid hormones. Namely, the receptor displays ...

Tracing water contaminants back to the source

Insidious PFAS contaminants are travelling long distances via our waterways but their unique 'signature' can give researchers clues about where they come from so they can be cleaned up.

Cellular microRNA detection with miRacles

MicroRNAs (miRNAs) are short noncoding regulatory RNAs that can repress gene expression post-transcriptionally and are therefore increasingly used as biomarkers of disease. Detecting miRNAs can be arduous and expensive as ...

Study first to show processes determining fate of new RNA pesticides in soils

A new generation of pesticides can be used to control pest insects by compromising the bug's ability to create essential proteins. These gene-silencing pesticides can be genetically engineered into agricultural crops such ...

Warmer water, chemical exposure influence gene expression across generations in a coastal fish

Warmer water temperatures, combined with low-level exposure to chemicals already known to be harmful to aquatic life, influence the expression of genes in the offspring of an abundant North American fish species—and threaten ...

Huge step forward in decoding genomes of small species

For the first time, scientists have read the whole genetic code of one single tiny mosquito. Traditionally, it has been difficult to extract enough DNA from insects and other small organisms to build a high quality genome ...

The energy implications of organic radical polymers

Texas A&M University professor Dr. Jodie L. Lutkenhaus is one step closer to realizing her goal of creating a battery made entirely of polymers, which has the potential to charge and discharge much faster than traditional ...

Store craft beer in a cool place and consume it as fresh as possible

A new study by the Leibniz-Institute for Food Systems Biology at the Technical University of Munich (Leibniz-LSB@TUM) shows that craft beer should be kept cool and consumed as fresh as possible. After three months, cold stored ...
