Foul fumes pose pollinator problems
A team led by researchers at the University of Washington has discovered a major cause for a drop in nighttime pollinator activity - and people are largely to blame. The researchers found that nitrate radicals (NO3) in the air degrade the scent chemicals released by a common wildflower, drastically reducing the scent-based cues that nighttime pollinators rely on to locate the flower.

Surprisingly vibrant colour of 12-million-year-old snail shells
Surprisingly vibrant colour of 12-million-year-old snail shells
Researchers provide world's first evidence of intact polyene pigments in fossils Snail shells are often colourful and strikingly patterned. This is due to pigments that are produced in special cells of the snail and stored in the shell in varying concentrations. Fossil shells, on the other hand, are usually pale and inconspicuous because the pigments are very sensitive and have already decomposed.

Down to the Core of Poxviruses
Down to the Core of Poxviruses
ISTA researchers uncover the architecture of poxvirus cores A recent re-emergence and outbreak of Mpox brought poxviruses back as a public health threat, underlining an important knowledge gap at their core. Now, a team of researchers from the Institute of Science and Technology Austria (ISTA) lifted the mysteries of poxviral core architecture by combining various cryo-electron microscopy techniques with molecular modeling.

How to make bright quantum dots even brighter
How to make bright quantum dots even brighter
Researchers at Empa and ETH have developed methods for making perovskite quantum dots faster and more efficient emitters, thereby significantly improving their brightness. This is relevant for applications in displays as well as in quantum technologies. Quantum dots are a kind of artificial atom: just a few nanometres in size and made of semiconductor materials, they can emit light of a specific colour or even single photons, which is important for quantum technologies.

Green steel from toxic red mud
Green steel from toxic red mud
An economical process with green hydrogen can be used to extract CO2-free iron from the red mud generated in aluminium production The production of aluminium generates around 180 million tonnes of toxic red mud every year. Scientists at the Max-Planck-Institut für Eisenforschung, a centre for iron research, have now shown how green steel can be produced from aluminium production waste in a relatively simple way.

Grant of ¤700,000 to gain better understanding of nitrogen dioxide with GELSONDE
Nitrogen dioxide is a gas that has a high proportion of nitrogen precipitation and is hard to measure. But that could soon change: the Dutch Research Council (NWO) Open Technology Programme (OTP) has awarded ¤700,000 to the GELSONDE project, led by Paul Kouwer, from the Radboud University Institute for Molecules and Materials.

Cosmic building blocks of life discovered through the electron microscope
For the first time without any chemical treatment, a research team analyses extraterrestrial amino acids and other organic compounds in an English meteorite fall Meteorites are fragments of asteroids which find their way to Earth as shooting stars. These cosmic sediments have frozen the primordial soup from which our solar system emerged - preserving it just like a time capsule.
