Heard of zebra sharks? These beautiful creatures are extremely rare in the wilds of Indonesia and were at risk of going extinct due to overhunting.
But here's the good news - a group of 44 aquariums from around the world has come together to launch a massive captive-breeding-and-release program.
Their goal? To reintroduce 500 zebra sharks back into their native waters.
This is a huge effort, and it's the first time such a program has ever been attempted for sharks. Typically, rewilding is reserved for land animals.
Looks like these aquariums have some serious fin-nesse!
It's exciting to see that the protections for sharks and rays in areas like Raja Ampat, which is home to one of the most diverse marine environments in the world, are already helping populations to thrive. However, zebra sharks haven't seen the same benefits yet in Raja Ampat, which shows how difficult it can be to rewild creatures in the ocean. It's hard to control territories, limit movements, and keep track of threats.
Despite these challenges, the ReShark team, made up of aquarium experts, recently released their first batch of zebra shark eggs into the waters of Raja Ampat.
This location is 90 miles away from the nearest town and surrounded by stunning limestone pinnacles hovering over turquoise seas. It's like they're giving these little guys their own private island!
Have you heard about the new way we're fighting climate change? Scientists have found a way to improve the technology of capturing CO2 from the air, which could make a real difference in the fight against global warming.
By adding copper to the filter material, the captured CO2 is converted into baking soda, which is harmless and can even be stored in the ocean or sold.
How cool is that?!
It's no secret that we need to limit the warming of the Earth to less than 1.5°C if we want to protect our planet for future generations. Carbon capture methods are one way we can achieve this, but until now, they've been limited to industrial facilities with underground storage capacity.
However, a recent study published in Science Advances shows that adding copper to the ammine-based filter devices can increase their efficiency by filtering out CO2 three times as much. Not only does this reduce cost, but it also opens up new possibilities for where the absorbed CO2 can be stored—in the ocean!
This means that carbon-capture facilities can now be placed anywhere along the coastline, not just in areas with significant underground storage capacity.
We’ve now got an incredible new surgical tool that can both perform surgery and 3D-print living cells inside the human body in real-time. It's insane what robots are capable of these days!
Engineers from the University of New South Wales in Sydney have created a device that includes a water jet, scalpel, and endoscopic camera, all in one!
🤔What is it?
It's a tiny flexible 3D bioprinter that can be inserted into the body just like an endoscope and deliver multilayered biomaterials directly onto the surface of internal organs and tissues.
⚙️What’s 3D bioprinting?
The process of 3D bioprinting involves the fabrication of biomedical parts from bioink to form natural tissue-like structures. It's usually used for research purposes such as tissue engineering and developing new drugs.
🤷♀️How’s it different from what we did before?
Previously, 3D bioprinting required the use of large machines to produce cellular structures outside the living body. But this new device can do it all right inside the body!
The research team tested the device inside an artificial colon, and it was able to navigate through confined spaces before successfully 3D printing. The proof-of-concept device, known as F3DB, has a highly maneuverable swivel head that prints the bioink, attached to a long and flexible robotic arm that can be controlled externally.
The team believes that with further development, the technology could be used by medical professionals to access hard-to-reach areas inside the body via small skin incisions or natural orifices within the next five to seven years!
Delegates from different countries came together at the Our Ocean Conference in Panama to pledge billions of dollars to protect our oceans. They committed to funding marine protected areas and biodiversity corridors, with a total of 341 commitments worth nearly $20 billion! This is in addition to the previous Our Ocean conferences, which have generated over 1,800 commitments worth $108 billion.
Panama's president, Laurentino Cortizo Cohen, emphasized the importance of the conference as an opportunity for countries to work together to preserve and strengthen the ocean's life. In fact, Panama itself committed to expanding its Banco Volcán Marine Protected Area, adding 36,058 square miles of protection to the Caribbean Sea.
Moreover, the conference saw many other commitments, such as Panama's pledge to stop 160,000 tons of plastic from being imported and consumed by eliminating single-use plastics, and charitable organizations establishing a $51 million fund to help nations protect 30% of oceans by 2030.
Meanwhile, the Connect to Protect Eastern Tropical Pacific Coalition pledged $118.5 million to strengthen marine protections for the Eastern Tropical Pacific Marine Corridor.
Even the US and the European Union pledged large sums of money to protect marine biodiversity, with $6 billion and $865 million respectively.
On March 27, 1845, Wilhelm Conrad Röntgen, a German physicist, was born. He accidently discovered X-Rays!
👀 Here’s the story:
It happened on November 8, 1895, while he was experimenting with electric current flow in a partially evacuated glass tube (also known as a cathode-ray tube).
During his experiment, Röntgen noticed that a screen made of barium platinocyanide, located far from the tube, emitted light when the tube was in operation. Curious, he theorized that when the cathode rays (electrons) hit the glass wall of the tube, they produced an unknown form of radiation that traveled across the room and caused the screen to fluoresce.
Further investigation led Röntgen to discover that this new form of radiation was able to pass through certain materials such as paper, wood, and aluminum. He also found out that it affected photographic plates, but unlike light, it didn't exhibit any properties of reflection or refraction.
Thinking it was unrelated to light, Röntgen mistakenly believed that the rays were a completely new and undiscovered phenomenon. He named the discovery X-radiation due to its unknown nature, although it later became known as Röntgen radiation.
Röntgen's discovery paved the way for X-ray technology and medical imaging. He even took the first X-ray photographs of the interiors of metal objects and his wife's hand, which showed the bones inside.
