Australian researchers have developed a new material similar to super-wound wound glue, used to spray wounds, even internal injuries.
This glue works like any sealant or household tile adhesive, except it’s made from natural elastic protein.
“A good surgical sealant should have several properties: elastic, adhesive, non-toxic and biocompatible,” said Nasim Annabi of Northeastern University, an author of the study. “But most sealants on the market have only one or two of these properties, not the whole. We have the desire to create a material with all of these properties, ”
Their product, nicknamed MeTro, is biocompatible because it is made from the same protein that makes up connective tissue, which connects cells in humans. In addition, after UV light, this MeTro adhesive will harden in 60 seconds.
The application potential is enormous. “Whether it’s a war zone, in accidents or in cases where surgery is needed faster, wider, just spray it on. This small canister, [just] sprayed it on the area to be treated, whether a lung is punctured, or a blood vessel is broken, ”GS. biochemist Anthony Weiss of the University of Sydney said.
The Australian university has partnered with Harvard and Northeastern USA to develop the prototype of the glue and is now preparing for clinical trials in humans.
The glue could replace braces, traditional medical sutures, and make it easier to treat inaccessible internal injuries, researchers say.
Because of its natural elasticity, it is an ideal solution for bulging, collapsed tissues such as the heart, lungs, and blood vessels.
“Then it decomposes without causing poison. It achieves all the elements of a highly effective and versatile surgical sealant. ”
The research was published in the journal Science Translational Medicine and the group is seeking funding to conduct clinical trials in humans.
Son Doong Cave – the ‘Secret Gate’ to another underground world
Son Doong is a cave that people cannot forget once they arrive. It was mysterious, seductive and had magical power. The massive scale and the unique vegetation in the cave make Son Doong cave ranked 6th by CN Traveler in the list of surreal beauty in the world.
Secret gate and accidental discovery
Son Doong Cave was first found in 1991 by a local man named Ho Khanh, who once stopped to take shelter from the rain when searching for aquilaria in Phong Nha – Ke Bang National Park area.
Ho Khanh could not have imagined that the journey to find the bass would help him discover the world’s largest cave with magical beauty.
Returning home after first discovering a strange cave, a few days later Ho Khanh thought about returning to the cave to explore more, but he could not remember the exact location. Finally, the story of the strange cave was gradually forgotten by Khanh.
When members of the British Cave Research Association (BCRA) Howard and Deb Limbert conducted a Phong Nha survey and studied caves in this area, one day, they talked to Khanh, he mentioned the charming cave that he had been to.
The British cave explorers were mesmerized by what Khanh told and encouraged him to try to find it again.
But they failed many times trying to find the cave. And only when he thought there was never a chance again, in 2008, Ho Khanh found the ‘gateway to another world’, a huge cave that had been hiding for centuries, far from reach. human.
He led British cave explorers to the cave in 2009, and they made their first expedition into what would later become known as the Son Doong cave – meaning the ‘Mountain River Cave’.
Huge cave with magical beauty
According to geologists, Son Doong cave was formed about 2 – 5 million years ago, when river water flowed across the limestone area buried along a fault line. The water eroded and created a giant tunnel like today.
Son Doong is a huge cave, it is considered the largest cave in the world that has been discovered by humans so far. It is so large that a Boeing 747 can easily fly over the largest cave.
Many people who have stepped in here say they have never seen the same thing anywhere else in the world.
Inside the cave is a huge ecosystem, the forest is so large that it makes you feel like you are entering another world.
Australian photographer John Spies, who spent a week living in the cave, described it in an interview with NYPost.
“Going into the cave makes us feel small and humble,” said John Spies. Surprisingly, going into [eight kilometers], daylight still illuminates the caves. The size of the cave is unbelievable … Having a five-night camp in the world’s largest cave is not something anyone will experience in life. ”
“Its entrance is quite small and dense, caused by the cold air inside interacting with the hot air outside, flooding the forest around the edge of the cave entrance,” Mr. Spies said.
“This cave is even harder to access than Batman’s cave”
To enter the cave, visitors must climb over a rock wall nearly 90m high, using harnesses and ropes (this wall is now fitted with a stainless steel ladder). After that, they had to overcome large piles of boulders and crept under limestone blocks as big as the whole house.
The new primary ecosystem is the most attractive point of Son Doong cave
According to cave explorers in Vietnam, Son Doong’s unique feature is not only its largest size in the world, but also its primary ecosystem.
Son Doong possesses an ecosystem separate from the outside world, including the blind fauna and albino animals deep inside the cave, never exposed to sunlight.
Because many parts of the cave are exposed to sunlight, the explorers discovered an entire primeval forest with rich vegetation, without any trace of humans for millions of years. Experts have even called the forest in this cave a “garden of Eden” in honor of its beautiful beauty.
Because the number of people visiting each year is very limited to protect the ecosystem here, what we know about Son Doong is still very little. In the future, surely new discoveries about Son Doong will bring us more surprises about the world’s largest cave.
