Young designer creates plastic alternative from fish waste and algae

It hopefully will be used to wrap sandwiches or carry baked goods instead of the cling wraps and plastics now on the market. The winning design for this year’s international James Dyson Award is a plastic alternative made out of…

Dead-zone report card reflects improving water quality in Chesapeake Bay

The 2019 ‘dead-zone’ report card for Chesapeake Bay indicates that the volume of low-oxygen, ‘hypoxic’ water was on the high end of the normal range, a finding that scientists consider relatively good news given the unfavorable weather conditions.

The unexpectedly weird and beautiful world of lichens

Lichen is something we commonly see growing on rocks or tree branches, on old wood fences and rotting stumps. But how often do you stop to really ponder lichens? Probably not often. And yet lichens are surprisingly fascinating … and…

Lichens are way younger than scientists thought

(Field Museum) Lichens — a combo of fungus and algae — can grow on bare rocks, so scientists thought that lichens were some of the first organisms to make their way onto land from the water, changing the planet’s atmosphere and paving the way for modern plants. But a closer look at the DNA of the algae and fungi that form lichens shows that lichens likely evolved millions of years after plants.

The global distribution of freshwater plants is controlled by catchment characteristics

(Faculty of Science – University of Copenhagen) Unlike land plants, photosynthesis in many aquatic plants relies on bicarbonate in addition to CO2 to compensate for the low availability of CO2 in water. A study in the scientific journal SCIENCE by Iversen and co-authors shows that the abundance of plant species with the ability to use bicarbonate increases in hard water lakes with greater bicarbonate concentrations. In streams, where the CO2 concentration is higher than in air, bicarbonate users are few.

Latest Climate Culprits: Asthmatics

By now you should know that you hate the planet if you eat beef, instead of mashed-up bugs or heavily salted soy protein or algae or whatever. And of course, you hate the planet if your car uses gasoline instead…

Eelgrass acid and resveratrol produced by cell factories for the first time

Scientists are now able to produce a wide range of sulfated aromatic compounds such as antifouling eelgrass acid, resveratrol and vanillic acid derivatives using microbial production hosts. This pioneering work could lead to new environmentally friendly anti-fouling paint for ships, as well as improved and sustainable nutraceuticals and medicine.

Global Warming Is Already Destroying New England’s Fisheries – The New Republic

To wake up in the Northeastern United States—as California blazes and Japan digs itself out of typhoon damage—is to experience an uneasy gratitude for all that is not burning, battered or underwater. Seven years out from Superstorm Sandy, we know…
