Seaweed supplements cut cattle methane emissions by up to 82% Cattle are a major source of greenhouse gas emissions, mainly due to their methane-loaded burps.

Seaweed supplements cut cattle methane emissions by up to 82%

A detailed new study has found more evidence that feeding cows a small seaweed supplement can greatly reduce their methane emissions, without affecting their health or the taste of the meat. Methane might not be as abundant a greenhouse gas as carbon dioxide, but it makes up for that in potency – over a 20-year period it traps 84 times more heat than CO2.

Agriculture is the biggest contributor of the gas, with livestock belching out 37 percent of all human-induced methane. As such, calls are increasingly being made for people to reduce the amount of red meat they eat. The Savory Possibilities of Sea Beans. Article body copy.

Crab-22: how Norway's fisheries got rich – but on an invasive species. The Norwegian fishing village of Bugøynes, 310 miles north of the Arctic Circle and a frigid, dark place for much of the year, was on the edge of ruin.

Crab-22: how Norway's fisheries got rich – but on an invasive species

Work was scarce. Years of overfishing and mismanagement had stymied cod quotas. Boats lay idle in cold waters. Those who chose to stay were forced to rely on what meagre wages they could still muster from fishing and processing. Scientists grew trees from 2000-year-old seeds and the outcome may be delicious. Two thousand years ago, the Roman Empire dominated the world, and it had a favorite fruit — dates.

Scientists grew trees from 2000-year-old seeds and the outcome may be delicious

Ancient dates — varieties of the fruit that eventually led to the basis of the bacon-wrapped treats we know and love today — were a coveted commodity two millennia ago. Now, researchers have successfully germinated some of those ancient seeds, recreating the tasty fruit-bearing trees of yore and their caramel-like bounty. In a study published Wednesday in the journal Science Advances, researchers describe how they were able to grow date-palm trees from six 2,000-year-old seeds found in southern Israel. The seeds are a little different to modern-day date-palm seeds — they are “significantly longer and wider than both modern date varieties and wild date palms,” say the researchers. In Mexico City, the coronavirus is bringing back Aztec-era ‘floating gardens’ This story was originally published by Atlas Obscura and is reproduced here as part of the Climate Desk collaboration.

In Mexico City, the coronavirus is bringing back Aztec-era ‘floating gardens’

In the south of Mexico City, about 100 miles of murky canals wind their way through the Xochimilco neighborhood. Here, the urban sprawl of one of the world’s densest cities yields to a lake region where indigenous farmers have been cultivating a unique system of floating gardens since precolonial times. Called chinampas, these floating gardens were built by the Aztecs to feed a growing population. Harvester pulls record amount of drinking water out of thin air. Clean water is all around us, and more literally than you might think – it's floating around in the air most of the time.

Harvester pulls record amount of drinking water out of thin air

Of course, it’s not particularly drinkable in that form, but now researchers at the Johns Hopkins Applied Physics Lab (APL) have found materials that can collect huge amounts of water from the air. As is the case with similar systems we've covered previously, the key lies with a material called a metal-organic framework (MOF). These structures have the highest surface area of any known material – in fact, if you were able to unfold just one gram of an MOF, it would be enough to cover a football field. And all that internal space makes them perfect for capturing and storing water. Plenty of previous studies have managed to use MOFs to absorb water vapor from the air and collect it in liquid form for drinking. Almonds are out. Dairy is a disaster. So what milk should we drink? For environmentally minded consumers, the news is hard to swallow: almond milk is not healthy for the planet and the popular milk substitute is especially hard on bees.

Almonds are out. Dairy is a disaster. So what milk should we drink?

Our recent investigation into the connection between California’s industrialized almond industry and a record 50bn commercial bee deaths created quite a buzz. The widely read story prompted one primary response from readers: “What should we be drinking instead?” This is a thorny question, and food sustainability experts are reluctant to single out any one plant milk as best because all have pros and cons. But we’re going to try. One thing is clear. Kenya Installs The First Solar Power Plant That Transforms Ocean Water Into Drinking Water.

While most of us, who also have the privilege of using the Internet on a daily basis and therefore are able to read this, don’t have any problems getting fresh drinking water, that’s not the case for everyone.

Kenya Installs The First Solar Power Plant That Transforms Ocean Water Into Drinking Water

Around 2.2 billion people struggle because they don’t have safe access to drinking water which could seem pretty ironic considering we live on a planet that is 2/3 water. But no need for those long faces as there might be a solution to this problem. Recently, the NGO Give Power installed a solar-powered plant that transforms salty ocean water into fresh drinking water and thus helps 25,000 people a day! More info: Give Power The NGO, Give Power, conducted their first solar-powered water transforming plant test early in August this year. Harvester Turns Water Into Air. Mathieu Prévot, UC Berkeley Researchers at UC Berkeley created a water harvester that can pull more than five cups of water from low humidity air per day per 2.2 pounds of water-absorbing materials.The goal is to create massive systems to harvest water for entire villages.This method actually produces enough water for you to survive in extreme circumstances, with some left to spare.

Harvester Turns Water Into Air

It sounds like a magic trick, but in a new paper for the Journal of the American Chemical Society, researchers from the University of California, Berkeley have unveiled a device that can literally turn thin air into water. The scientists' water harvester can pull more than five cups of water from low humidity air per day per 2.2 pounds of water-absorbing materials. These, called metal-organic frameworks, are rather porous. That means you could produce enough water to live for a day. How Microbes Could Upend America’s Toxic Dependence on Nitrogen Fertilizer. Crabs, clams, and worms die almost immediately. Fish, shrimp, and any animal that can swim quickly enough make valiant, though often doomed, efforts to flee. There are few places to go in a dead zone that can reach the size of New Jersey. The Gulf of Mexico hypoxic zone — or “dead zone,” as it’s more commonly known — is a stretch of seawater where vast swaths of slimy algae bloom annually.

When the algae eventually die, they decompose, sucking up so much of the water’s oxygen that all nearby aquatic life suffocates. In 2017, this dead zone measured 8,776 square miles, the largest since scientists at the National Oceanic and Atmospheric Administration began recording it in 1985. Meet the guy who’s farming the seas to save them. When Bren Smith first started farming kelp, he was embarrassed. He’d spent his life as a commercial fisherman, eating raw salmon he’d scooped out of the sea and exchanging harrowing, near-death tales in darkened bars. He vowed to never eat seaweed, even the stuff he grew, and for a while, when guys on the docks would ask him what he farmed, he’d sputter “Ah, I’m growin’ hemp.”

But the initial embarrassment gave way to a stronger sense of purpose — he’d found a way to return to the sea that, unlike the fishing he knew and loved (and the fish farming he knew and hated), wasn’t destroying it. Now he proudly calls himself an ocean farmer. Keep eating fish; it’s the best way to feed the world. America’s Next Agricultural Revolution Will Happen Indoors. Rod Rosenstein was a #Resistance hero—and one of Donald Trump’s favorite whipping boys—for overseeing the Russia investigation. But Rosenstein’s legacy at the Justice Department shows he was more than happy to oblige the White House on one of its top priorities: spearheading the president's war on leakers and whistleblowers. Cases involving the leak of classified information are high profile prosecutions that would be part of the purview of any deputy attorney general.

But former Justice Department officials tell The Daily Beast that Rosenstein was deeply involved in bringing the cases as a result of both pressure from the White House and a personal view of the importance of prosecuting unauthorized disclosures. The Justice Department’s record of prosecutions under Rosenstein in just two years shows how aggressively he pursued cases. It’s a data point that may surprise Trump’s #Resistance critics. Local startup dives into the seafood snack industry. Nicolas Mendoza, founder and CEO of OneForNeptune, poses with a bag of his Honey Lemon Ginger fish jerky.
