Pomponi, Ph.D. Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for many organisms, including freshwater and terrestrial invertebrates.Despite many efforts over multiple decades, there are still no cell lines for marine invertebrates including marine sponges, which are the source of thousands of novel chemicals with pharmaceutically relevant properties. Supply of these chemicals also is a bottleneck to development of sponge-derived drug leads, because wild harvest is not ecologically sustainable, and chemical synthesis is challenging due to the complexity of many of the bioactive chemical compounds.Researchers from Florida Atlantic University’s Harbor Branch Oceanographic Institute and collaborators at Wageningen University in the Netherlands have developed a breakthrough in marine invertebrate (sponge) cell culture. For the first time, they have accomplished a sub...

The Nikon Nikkor Z 24-70mm f/2.8 S is a standard zoom with lens outstanding optical performance and a pro-grade build. Nikon understands that if it wants to get pros excited about its mirrorless system, it needs to have the lenses to match. So it’s no surprise that the Nikkor Z 24-70mm f/2.8 S ($2,299.95), a must-have lens for most working photographers, is an early entry. Nikon’s most recent take on the design is an exceptional performer, one of the sharpest 24-70mm f/2.8 zooms we’ve seen for any system, but it also comes with a premium price—it’s one of the most expensive lenses of this type on the market. That doesn’t stop it from earning Editors’ Choice marks—it’s the standard zoom you’ll want to pair with your Nikon Z camera for sure. The Nikkor Z 24-70mm f/2.8 is around the same size and weight as similar lenses for other systems. It measures 4.9 by 3.5 inches (HD), weighs 1.8 pounds, and supports 82mm front filters. If you prefer a smaller, lighter zoom, the Nikkor Z 24-70mm f...
