University of Adelaide researchers have discovered how grapes “breathe”, and that shortage of oxygen leads to cell death in the grape. 

Imagine if carbon dioxide (CO2) could easily be converted into usable energy. Every time you breathe or drive a motor vehicle, you would produce a key ingredient for generating fuels. Like photosynthesis in plants, we could turn CO2 into molecules that are essential for day-to-day life. Now, scientists are one step closer.

Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are part of a scientific collaboration that has identified a new electrocatalyst that efficiently converts CO2 to carbon monoxide (CO), a highly energetic molecule. Their findings were published on Feb. 1 in Energy & Environmental Science.

As ice the melts, the organic carbon found in permafrost is being released once again after ages of confinement in the soil. It is making its way into Arctic and subarctic lakes and ponds, and modifying their composition. The portrait presented by an international team of researchers that includes Professor Isabelle Laurion of INRS shows the influence that thawing permafrost has on surface water biogeochemistry. Published in Limnology and Oceanography Letters, the results demonstrate that organic carbon from permafrost is making its way into the waters of these regions. This type of carbon is particularly good at absorbing sunlight. As a result, these water bodies are getting increasingly darker and stratified, which affects a number of biological processes in these ecosystems.

Backed by the iconic Table Mountain, Cape Town, South Africa’s second-largest metropolis, seduces increasing numbers of international travelers. Its charismatic neighborhoods, bright beaches, and breathtaking natural landscapes garner shelves-full of tourism awards and terabytes of glowing Instagram posts.

Recently, Cape Town also has become infamous as the home of “Day Zero,” the day when most of the city’s taps are predicted to run dry. With its major, rain-fed supply dams dangerously low after three years of drought, most of the city’s 4 million-plus residents — some rich, many desperately poor — have been facing the prospect of lining up at emergency water distribution points to collect a daily ration of just 6.6 gallons per person sometime before June or July. That’s when winter rains normally begin filling the reservoirs of this Southern Hemisphere city.

For the past 40 years, the total number of Adélie Penguins, one of the most common on the Antarctic Peninsula, has been steadily declining—or so biologists have thought. A new study led by researchers from the Woods Hole Oceanographic Institution (WHOI), however, is providing new insights on of this species of penguin.
