Cold-water coral traps itself on mountains in the deep sea      (via sciencedaily.com)     Original source 

Corals searching for food in the cold and dark waters of the deep sea are building higher and higher mountains to get closer to the source of their food. But in doing so, they may find themselves trapped when the climate changes.

Controlling root growth direction could help save crops and mitigate climate change      (via sciencedaily.com)     Original source 

Scientists have determined how the well-known plant hormone ethylene is crucial in controlling the angle at which roots grow. The findings can be used to engineer plants and crops that withstand the environmental stresses of climate change and drought, and perhaps to create plants that remove carbon dioxide from the atmosphere and store it deep underground to help mitigate climate change.

Biomanufacturing using chemically synthesized sugars enables sustainable supply of sugar without competing with food      (via sciencedaily.com)     Original source 

Researchers have succeeded in biomanufacturing from chemically synthesized sugar for the first time in the world. With refinement of this technology, one can envision a future society in which the sugar required for biomanufacturing can be obtained 'anytime, anywhere, and at high rate'. In the future, biomanufacturing using chemically synthesized sugar is expected to be a game changer in the biotechnology field -- including the production of biochemicals, biofuels, and food, where sugar is an essential raw material -- ultimately leading to the creation of a new bio-industry.

Frequent marine heatwaves in the Arctic Ocean will be the norm      (via sciencedaily.com)     Original source 

Marine heatwaves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions -- as shown in a new study.

Greenland's ice sheet is melting -- and being replaced by vegetation      (via sciencedaily.com)     Original source 

An estimated 11,000 sq miles or 28,707 sq kilometers of Greenland's ice sheet and glaciers have melted over the last three decades, according to a major analysis of historic satellite records.

If we can't untangle this mess, Norway's blue industry will never be green      (via sciencedaily.com)     Original source 

For the first time, researchers have investigated how ropes and fishing lines are handled by the Norwegian commercial fishing industry. The fishing fleet loses almost 400 tons of rope in Norwegian waters every year.

Polar bears unlikely to adapt to longer summers      (via sciencedaily.com)     Original source 

More time stranded on land means greater risk of starvation for polar bears, a new study indicates. During three summer weeks, 20 polar bears closely observed by scientists tried different strategies to maintain energy reserves, including resting, scavenging and foraging. Yet nearly all of them lost weight rapidly: on average around 1 kilogram, or 2.2 pounds, per day. Some have speculated that polar bears might adapt to the longer ice-free seasons due to climate warming by acting like their grizzly bear relatives and either rest or eat terrestrial food. The polar bears in this study tried versions of both strategies -- with little success.

Compounds released by bleaching reefs promote bacteria, potentially stressing coral further      (via sciencedaily.com)     Original source 

New research revealed that when coral bleaching occurs, corals release unique organic compounds into the surrounding water that not only promote bacterial growth overall, but select for opportunistic bacteria that may further stress reefs.

Global deforestation leads to more mercury pollution      (via sciencedaily.com)     Original source 

Researchers find deforestation accounts for about 10 percent of global human-made mercury emissions. While it cannot be the only solution, they suggest reforestation could increase global mercury uptake by about 5 percent.

Not only in information technology: Restart also works in chemical simulations      (via sciencedaily.com)     Original source 

Scientists have discovered that a known practice in information technology can also be applied to chemistry. Researchers found that to enhance the sampling in chemical simulations, all you need to do is stop and restart.

Key advance for capturing carbon from the air      (via sciencedaily.com)     Original source 

A chemical element so visually striking that it was named for a goddess shows a 'Goldilocks' level of reactivity -- neither too much nor too little -- that makes it a strong candidate as a carbon scrubbing tool.

Towards A Better Way of Releasing Hydrogen Stored in Hydrogen Boride Sheets      (via sciencedaily.com)     Original source 

Hydrogen stored in hydrogen boride sheets can be efficiently released electrochemically, report scientists. Through a series of experiments, they demonstrated that dispersing these sheets in an organic solvent and applying a small voltage is enough to release all the stored hydrogen efficiently. These findings suggest hydrogen boride sheets could soon become a safe and convenient way to store and transport hydrogen, which is a cleaner and more sustainable fuel.

Researchers unveil method to detect 'forever chemicals' in under 3 minutes      (via sciencedaily.com)     Original source 

PFAS have earned the name 'forever chemicals' with good reason -- the human-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply.

'Legacy' phosphorus delays water quality improvements in Gulf of Mexico      (via sciencedaily.com)     Original source 

The same phosphorus that fertilizes the thriving agriculture of the Midwest is also responsible for a vast 'dead zone' in the Gulf of Mexico near the Mississippi Delta. Efforts to reduce the amount of phosphorus that enters the Mississippi River system are underway, but research suggests that remnants of the contaminant are left behind in riverbeds for years after introduction and pose an overlooked -- and lingering -- problem.
