A research team has developed a method for extracting gold from electronics waste, then using the recovered precious metal as a catalyst for converting carbon dioxide (CO2), a greenhouse gas, to organic materials.

System to auto-detect new variants will inform better response to future infectious disease outbreaks
Researchers have come up with a new way to identify more infectious variants of viruses or bacteria that start spreading in humans -- including those causing flu, COVID, whooping cough and tuberculosis.
Key players in brain aging: New research identifies age-related damage on a cellular level
Scientists have identified the molecular changes that occur in the brains of aging mice and located a hot spot where much of that damage is centralized. The cells in the area are also connected with metabolism, suggesting a connection between diet and brain health.
Ancient DNA unlocks new understanding of migrations in the first millennium AD
Waves of human migration across Europe during the first millennium AD have been revealed using a more precise method of analysing ancestry with ancient DNA, in research led by the Francis Crick Institute.
Enhanced Raman microscopy of cryofixed specimens: Clearer and sharper chemical imaging
A team has reported a Raman microscopy technique that produced images up to eight times brighter than those achieved with conventional Raman techniques. Imaging of frozen biological samples reduced the noise introduced by the motion of material over long acquisition times. The technique is expected to broaden understanding in many...
People who are immunocompromised may not produce enough protective antibodies against RSV after vaccination
Researchers have shown that people 60 years or older with weakened immunity do not respond as strongly to vaccines against the respiratory syncytial virus (RSV) as people in the same age group with normal immune function.
Urgent action needed to protect the Parma wallaby
The creation of more fox-free safe havens and greater collaboration between government and landowners is needed to ensure the survival of a species of wallaby, an expert argues. The Parma wallaby, also known as the white-throated wallaby, is listed as a vulnerable species in Australia, while the International Union for...
How do monkeys recognize snakes so fast?
A researcher has found that the rapid detection of snakes by monkeys is because of the presence of snake scales as a visual cue. His findings highlight an evolutionary adaptation of primates to identify snakes based on specific visual features. Understanding these mechanisms provides insight into the evolution of visual...
Scientists discover a ‘Goldilocks’ zone for DNA organization, opening new doors for drug development
In a discovery that could redefine how we understand cellular resilience and adaptability, scientists have unlocked the secret interactions between a primordial inorganic polymer of phosphate known as polyphosphate (polyP), and two basic building blocks of life: DNA and the element magnesium. These components formed clusters of tiny liquid droplets...
Fly vs. wasp: Stealing a defense move helps thwart a predator
Many flies are plagued by parasitic wasps, which lay their eggs in fly larvae, turning them into surrogate wombs for wasp larvae. One common fly has successfully fought off its wasp predator by stealing a gene from bacteria that originated in bacteriophage. Biologists inserted that gene into other flies, making...
