First up…

Seafood is eaten by billions of people all over the world.

But meeting the demand for lots of seafood can lead to overfishing.

overfishing

This is when people catch fish faster than stocks can replenish, which can threaten the long-term survival of fish populations.

The Filet

To try to address this problem while meeting the demand for fish, Scientists at Revo Foods have created “The Filet,” which is designed to taste like real fish, and is thought to be the world’s first 3-D printed vegan alternative for salmon to hit grocery stores.

It is created using a mycoprotein made from fungi and also includes added vitamins and minerals normally found in fish.

To get its natural look, the ingredients are printed layer by layer to match the appearance of a real salmon fillet.

Despite it looking like the real thing, this vegan salmon contains less essential nutrients.

However, scientists hope that their sustainable alternative will prove a hit with taste buds and help reduce some of the environmental impacts of overfishing.

Up next…

UNESCO World Heritage Sites are places around the world that are considered to be of great historical, cultural, or scientific importance.

As a result, they are given special protection under an international agreement known as the World Heritage Convention.

Hawai‘i Volcanoes National Park

The Hawai‘i Volcanoes National Park is just one of 25 in the United States.

Grand Canyon National Park

Others include Grand Canyon National Park,

Yellowstone National Park

and the Old tea forests of Pu’er in southwestern China were among the new additions.

These are only a small selection of the wonders our world has to offer.

Perhaps there is one near you that is waiting to be explored?

And finally…

In 2018, off the coast of California, scientists discovered thousands of octopuses nesting in the thermal springs of an extinct underwater volcano.

They estimated that there could be as many as 20,000 at the site, which is now nicknamed the “octopus garden.”

Scientists spent three years studying the nesting animals to find out why the site is so popular.

They discovered that the eggs of the octopuses nesting there were ready to hatch in less than two years—several years quicker than expected for deep sea octopuses.

This led scientists to conclude that the heat from the thermal springs was speeding up the development of the animals’ eggs, allowing them to hatch sooner.

Scientists also noted that the shorter nesting time reduced the risk of harm from predators.

They believe that the heat and reduced nesting time is what makes it such a popular area for octopuses.

Now, scientists are eager to learn even more about the effects of this natural phenomenon.

That’s all for this week, we’ll see you next time!
