Ep. 97 Humpback Whales Hunting and NASAs New Spacesuit | Twig Science Reporter


On this week’s news update– New evidence of hunting techniques
by humpback whales– NASA unveils a new
prototype spacesuit– and a one-thousand-seven-hundred-
year-old shipwreck full of Roman supplies! First up– Humpback whales are known
for their clever hunting techniques. Some of them have learned
how to blow bubbles while swimming in circles
around groups of fish. This traps the fish in
a kind of “net” made of bubbles. Then the whales open their mouths
and scoop up their prey! Now, for the first time,
scientists have confirmed that humpbacks also use their flippers
to help guide the fish into their mouths! They think that the whales flash
the white underside of their flipper to scare the trapped fish,
making them easier to scoop up. Hunting in this way
uses up a lot of energy, so the scientists say
it must really be worth it to get a bigger mouthful of fish! Next up– Walking on the Moon
is a super-cool ambition that some of us might dream about, and now NASA has made that
even cooler with the unveiling of a new prototype spacesuit! This spacesuit aims
to be more comfortable and easier to move in
than previous versions. And, for the first time,
it’s been specially designed to fit not just male,
but female astronauts too! Versions of this suit will be worn
during the Artemis Mission in 2024, when the first woman is expected to
set foot on the surface of the Moon! And finally– Marine archaeologists in Spain
have made an amazing discovery– a one-thousand-seven-hundred-
year old Roman shipwreck! The vessel was found
off the coast of Mallorca, containing almost one hundred jugs
called “amphorae.” The jugs are thought
to contain olive oil, wine, and a special fish sauce,
often carried by ships to Rome. But they can’t be unsealed just yet. First, they are very carefully
lifted from the ocean floor. The jugs are now being kept
at the Museum of Mallorca in pools of water,
ready to be desalinated. Desalination means removing any salt
that has built up around the jugs. If left untreated, the salt
could cause the jugs to crack. Once this process is complete,
archaeologists can find out exactly what’s inside! That’s all for this week. We’ll see you next time!
