Velvet Worm slime could inspire sustainable synthetic materials
Fibers produced from the slime exhibit a strength akin to nylon, yet they can dissolve in water and be reconstituted into new fibers from the solution In the tropical, temperate forests it calls home, the velvet worm uses a projectile "slime" to capture its prey. When it's ejected from the worm, the slime transforms into a gel before solidifying into stiff fibers upon exposure to air.

A scorching-hot exoplanet
A scorching-hot exoplanet
Through the Gemini-North Telescope in Hawai'i, the chemical composition of WASP-76 b is revealed in unprecedented detail, giving new insights also into the composition of giant planets. An international team led by Stefan Pelletier , a Ph.D. candidate at Université de Montréal's Trottier Institute for Research on Exoplanets announced today having made a detailed study of the extremely hot giant exoplanet WASP-76 b. Using the MAROON-X instrument on the Gemini-North Telescope, the team was able to identify and measure the abundance of 11 chemical elements in the atmosphere of the planet.

Deep-sea impacts of climate interventions
Waterloo professor is part of an emerging field that calls for establishing a governance framework for ocean-based climate interventions Faculty of Environment From its current capacity as a carbon sink to its potential as a site for generating renewable energy, and managing solar radiation, the ocean is increasingly at the forefront of discussions around climate mitigation strategies. However, efforts to develop ocean-based climate interventions expose the ocean to various threats that harm biodiversity, pollute, and change its very chemistry.

One step closer to developing a potentially ultraprotective sunscreen from our own melanin
A new discovery about the structure of melanin has brought scientists one step closer to developing a new, potentially ultra-protective sunscreen derived from a biological substance found in nearly all organisms. Researchers from McGill's Department of Chemistry, in collaboration with The Ohio State University and the University of Girona, have announced a major advance in understanding the fundamental structure of melanin and one of its components that turns light into heat, protecting the body from sun damage.

Chemists create nanomachines by breaking them apart
Some "broken" nanomachines better sense their environment while others gain the ability to control their activity over time, researchers at Université de Montréal find. CONTENU - "Every act of creation," Picasso famously noted, "is first an act of destruction." Taking this concept literally, researchers in Canada have now discovered that "breaking" molecular nanomachines basic to life can create new ones that work even better.
