How did the building blocks of life arrive on Earth?
Researchers have used the chemical fingerprints of zinc contained in meteorites to determine the origin of volatile elements on Earth. The results suggest that without 'unmelted' asteroids, there may not have been enough of these compounds on Earth for life to emerge.

Researchers identify signs tied to more severe cases of RSV
Clinician-scientists analyzed samples from patients' airways and blood, finding distinct changes in children with severe cases of RSV, including an increase in the number of natural killer (NK) cells in their airways. The descriptive study, which focuses on understanding the underpinnings of severe disease, may help to lay groundwork for identifying new targets for future treatments.
New 3D printing technique creates unique objects quickly and with less waste
A new technique enables makers to finely tune the color, shade, and texture of 3D-printed objects using only one material. The method is faster and uses less material than other approaches.
NASA's Hubble, New Horizons team up for a simultaneous look at Uranus
NASA's Hubble Space Telescope and New Horizons spacecraft simultaneously set their sights on Uranus recently, allowing scientists to make a direct comparison of the planet from two very different viewpoints. The results inform future plans to study like types of planets around other stars.
'Inside-out' galaxy growth observed in the early universe
Astronomers have used the NASA/ESA James Webb Space Telescope (JWST) to observe the 'inside-out' growth of a galaxy in the early universe, only 700 million years after the Big Bang.
Female crested gibbons display jerky, almost geometric patterns of movement. Researchers have studied these conspicuous movements, which are comparable to human dances. They describe the structure of the dances, their rhythm and the contexts in which the dances occur.
Genomic study identifies human, animal hair in 'man-eater' lions' teeth
Scientists analyzed hairs extracted from the broken teeth of two 19th century 'man-eater' lions. Their analysis revealed DNA from giraffe, human, oryx, waterbuck, wildebeest and zebra as prey, along with hairs that originated from the lions.
Scientists cut harmful pollution from hydrogen engines
Scientists have discovered a low-cost method to significantly reduce this pollution from hydrogen internal combustion engines by improving the efficiency of their catalytic converters. The researchers found that infusing platinum in catalytic converters with a highly porous material called Y zeolites greatly enhances the reactions between nitrogen oxides and hydrogen, converting unhealthful nitrogen oxides into harmless nitrogen gas and water vapor.
How your skin tone could affect your meds
Skin pigmentation may act as a 'sponge' for some medications, potentially influencing the speed with which active drugs reach their intended targets, a pair of scientists report.
