Victory for the Oceans! Covert nighttime operations arrest ten poachers in Africa!
The Gambia’s waters are rich in biodiversity, making them a hotspot for illegal fishing operations.
Sam Simon and its crew have been working with local authorities to defend, conserve and protect these waters, and our most recent patrol has resulted in one of our biggest success’ in African waters.
Over the course of a week, ten trawlers were arrested, meaning that their illegal nets will no longer bring destruction to these waters.
For the Oceans.
Sea Shepherd is an international, non-profit marine conservation organization that engages in direct action campaigns to defend wildlife, and conserve and protect the world’s oceans from illegal exploitation and environmental destruction.
Just when you think the ocean couldn’t get any weirder, it turns out there are viruses in it.
A new study reveals there are almost 200,000 distinct viral populations in the ocean.
That’s a lot more viruses than we previously thought.
A liter of sea water contains anywhere between 1-10 billion virus particles—most of which we don’t know anything about. Our understanding of these elusive microbial communities has just been coming into focus over the last few decades, and this new research is a huge step toward better understanding our oceans.
Previously, highest number we had for ocean viral populations was about 15,000, but this new study pretty much blows that already impressive number out of the water.
From 2009 to 2013, researchers analyzed samples from about 80 different sites all over the world, from sunny surfaces to thousands of meters down into the depths. They found more than 180,000 additional unique viral populations, bringing the total number of distinct viral populations to almost 200,000. And the diversity of these new populations is nothing short of impressive.
Understanding how viruses interact with bacteria is important to human health and viruses also play essential roles outside of our bodies.
Viruses kill so many marine microbes they actually release a really significant amount of carbon back into the environment, playing a critical role in the food chain, all the way down at the very bottom.
Viruses continue to be very mysterious and though this project uncovered a lot of new populations, there is still a lot we just don’t know.

Climate change threatens to make dry regions even drier, so scientists at UC Berkeley created a device to make water out of thin air.
At least one hundred million people live in desert regions around the world according to the UN, and they survive off of less than 25 cm of rainfall each year, and for many, even that minuscule water supply is under threat as the climate crisis is making dry areas even drier. So scientists at UC Berkeley have been experimenting with materials that can pull drinking water out of thin air.
That’s right, right out of thin air.
A chemist at the University of California, Berkeley reported that he and his colleagues have created a solar-powered device that could provide water to millions living in water-stressed regions.
At the device’s heart is a porous crystalline material, known as a metal-organic framework (MOF), that acts like a sponge: It sucks water vapor out of air, even in the desert, and then releases it as liquid water.
A single gram of an MOF can have the surface area of a football field, and depending on the metal and organic molecules they’re made of, MOFs can be tailored to capture various different things in their pores. For example, an MOF could have the ability to capture CO2 and turn it into the fuel methanol, or neutralizing nerve agents like sarin gas. The function the Berkeley scientists used their MOF for was extracting water vapor that’s present in the air.
The lead researcher behind the device started a private company called Water Harvesting.
The company’s plan is to launch a microwave-sized device that can supply 2 adults with enough water for their daily hydration and cooking needs. Eventually the research team envisions a harvester device big enough to supply a small village. If the devices end up being affordable, safe, and reliable enough, these metal-organic frameworks have the potential to turn even the driest desert into an oasis.
