Like another interesting advance in material science we looked at back in 2016, the team’s creation uses the unique properties of a protein as a starting point. Where that previous example took advantage of a protein’s counter-intuitive compression capabilities, the University of Kent team has drilled into the natural shock-absorbing abilities of a protein called talin, and used it to create a family of hydrogel materials called TSAMs (Talin Shock Absorbing Materials).

Westminster City Council are fighting back against people who urinate in public by treating walls with a pee paint that give perpetrators a nasty surprise if they attempt to relieve themselves on it.
The paint creates a water-repellent layer so that urine and other liquid bounce back onto the perpetrator doing the peeing, leaving them soaked.

Guys, just don't forget this...
Filipino Zoo Girl was displayed at the Coney Island Zoo in 1904. She was a zoo attraction among the monkeys and lizards to show off the new US possessions in the Philippines. She was bound by ropes. Visitors threw her peanuts.

Glass frog turning transparent as it sleeps
The researchers found that the frogs maintained roughly the same level of transparency while awake, calling, exercising, and under anesthetic.
However, when they were sleeping, the frogs were between 34 and 61 percent more transparent than during waking activity.
Optical spectroscopy on 13 frogs confirmed that a decrease in circulating red blood cells is the reason for the increased transparency on their undersides. Red blood circulation decreased by up to 89 percent, and the red blood cell signal was concentrated in the liver.

World's largest aircraft engine is fully operational and ready to test
Rolls-Royce says it's finished building the first demonstrator for its massive UltraFan engine, which will eventually hit the skies in airliners to be developed in the 2030s. Testing begins soon, with expectations of a 25% leap in efficiency.

This is the underside of an elephant's foot. The sole of an elephant is full of cracks. Like the fingerprint of people or the stripes of a zebra, those cracks are unique to each elephant. That means, if the tracking conditions are good, that you can identify an individual elephant just by its footprint. The amount of cracks also increases by age, so you can also get an indication of an elephant's age, just from its footprints.
Elephants communicate over long distances with infra sounds, inaudible to the human ear. In the feet of elephants, there are a lot of sensitive nerves that pick up these low frequencies from the ground. So, you could say that elephants can listen with their feet.

Secret ingredient found to help ancient Roman concrete self-heal
Concrete is the most commonly used building material in the world, but it’s not impervious to damage. Weather and stress can lead to tiny cracks, which can grow into much larger cracks that eventually threaten the integrity of the entire structure. That can require expensive maintenance or replacement to prevent catastrophic failure.
In contrast, ancient Roman structures have stood the test of time for more than two millennia. To find out how, scientists have long examined samples of the material under microscopes to study the composition and uncover the ingredients that bestow such strength.

Shellmet helmet is made of scallop shells – plus it looks like one
Utilizing a process developed by Prof. Hiroshi Uyama from Osaka University, the shells are first boiled and sterilized, then pulverized and rendered into calcium carbonate powder, which is mixed with powdered discarded plastic and rendered into pellets. Those "Shellstic" bioplastic pellets are subsequently poured into a helmet mold and heated, causing them to melt.
Once the bioplastic has cooled and hardened, the result is a helmet with a scallop-shell-inspired ribbed design. That design, along with the inclusion of the calcium carbonate, is claimed to make the helmet about 33% stronger than it would be otherwise. Additionally, the production process is said to generate approximately 36% fewer greenhouse gas emissions than if 100% virgin plastic were used.

Planetary Defense & Science Will Advance With New Radar on Green Bank Telescope
With a transmitter less powerful than a microwave oven, a team of scientists and engineers used the National Science Foundation’s Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA) to make the highest-resolution radar images of the Moon ever collected from the ground, paving the way for a next-generation radar system to study planets, moons, and asteroids in the Solar System.

Magnetic solution removes toxic "forever chemicals" from water in seconds
Scientists in Australia have developed an intriguing new technique for removing toxic “forever chemicals” from water. Adding a solution to contaminated water coats the pollutants and makes them magnetic, so they can easily be attracted and isolated.
In tests with small samples of PFAS-laden water, the team found that the technique could remove over 95% of most PFAS molecules, including over 99% of GenX – a particularly problematic chemical – within 30 seconds.

Bottlebrush-shaped molecules carry drug combos to combat cancer
Existing cancer drugs can be effective against the disease, but unfortunately they don’t always go exactly where they’re needed in the right amounts, leading to a range of toxic side effects. Groups of drugs can multiply the cancer-fighting potential – but it’s even harder to corral them to the target.
Scientists at MIT have developed bottlebrush-shaped molecules that can carry groups of different cancer drugs in just the right ratio. Tests in mice showed significantly improved outcomes compared to just giving the drugs loose.

Researchers have created a new class of robots that can shift between solid and liquid forms on demand. In a series of tests, these new bots could move and change shape to run obstacle courses, carry objects, or even escape from a jail cell like a Terminator.
Robots usually come in two flavors – there are the traditional ones that are hard and strong, but not particularly flexible. And then there are soft robots, which are more flexible but not as strong. For the new study, researchers at Carnegie Mellon University and the Chinese University of Hong Kong developed a new type of robot that combines the best of both worlds.

Billion-dollar startup Colossal Biosciences claims it has come a step closer to reviving the dodo, a flightless bird that has been extinct since the 17th century.
The futuristic plan is only possible now that the Dallas-based company has decrypted the dodo's entire genome, according to a press release.
The bird is the latest in the collection of long-gone animals that scientists want to bring back to life. The startup has previously said it plans to recreate the Tasmanian wolf and the woolly mammoth.
There's still a lot to be done before these birds can be brought back. Scientists can't recreate life from scratch, so they will have to figure out a way to put the dodo-specific genes into the embryo of a living animal.

It works as follows - you have a set of static pictures, you arrange them in a given order and prescribe the actions that should occur "between the images", and the newfangled artificial intelligence remakes it all into a video.
