How do you study a group of organisms with over 300,000 species, dispersed across all seven continents, and with up to 50 times as much DNA content as the human genome? This is the question posed to biologists studying the evolutionary history of flowering plants, called angiosperms, whose rapid diversification […]

Scarlett Howard, Author provided The intense colours of flowers have inspired us for centuries. They are celebrated through poems and songs praising the red of roses and blue of violets, and have inspired iconic pieces of art such as Vincent Van Gogh’s sunflowers. But flowers did not evolve their colour for our […]

Gravitational-wave astronomy is set to revolutionize our understanding of the cosmos. In only a few years it has significantly enhanced our understanding of black holes, but it is still a scientific field in its youth. That means there are still serious limitations to what can be observed. Currently, all gravitational […]

Oil and gas exploration in Ecuador. Credit: Julie Larson Maher/WCS Intact Forest Landscapes are critical for conserving biodiversity and fighting climate change. A new study from WCS and WWF reveals that nearly 20 percent of tropical Intact Forest Landscapes (IFLs) overlap with concessions for extractive industries such as mining, oil […]

The ring galaxy NGC 474 at a distance of about 110 million light years. The ring structure was formed by merging processes of colliding galaxies. Credit: DES/DOE/Fermilab/NCSA & CTIO/NOIRLab/NSF/AURA Using data from the MUSE instrument, researchers at the Leibniz Institute for Astrophysics Potsdam (AIP) succeeded in detecting extremely faint planetary […]

Hemispherical array of ultrasound transducers lifts objects off reflective surfaces. Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic fields which stably trapped and lifted a […]

A debris disk, which includes comets, asteroids, rocks of various sizes, and plenty of dust, orbits the star Beta Pictoris, which is blocked at the center of this 2012 image by a coronagraph aboard the Hubble Space Telescope. This is the visible-light view of the system. NASA’s James Webb Space […]
