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.

Let’s see the results

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.

The Google dudes can if they want to.
A new thing called Video Editing Tool .

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.
Animation on a new level

The most ambitious neural network is being developed by a team of former Google employees - AdeptAI promises to surprise everyone.

As planned, AI will be able to perform any task in the browser using text commands - you can ask to find a refrigerator for a specific budget, fill out a Google Spreadsheet, or order products for making hodgepodge (or other dish).

So far, in a beta test, you can sign up here , in the near future they promise to roll it out to the general public.

How immortal jellyfish turn back time

Achieving immortality is something that has driven human beings throughout much of their history. Many peculiar legends and fables have been told about the search for the elixirs of life. Medieval alchemists worked tirelessly to find the formula for the philosopher’s stone, which granted rejuvenating powers. Another well-known story is the travels of Juan Ponce de León, who, while conquering the New World, searched for the mysterious fountain of youth.

But to this day no one has succeeded in discovering the keys to eternal life. There is, however, one exception – a creature no more than four millimetres in size Turritopsis dohrnii, also known as “the immortal jellyfish”.

A Strange New Form of Ice Discovered by Scientists Could Revolutionize How We Think About Water


A previously unidentified type of ice that is more similar to liquid water than any other ice yet has been discovered by scientists by shaking regular frozen water around in a jar of extremely cold steel balls.

This is amorphous ice, which does not exist in the environment on Earth. This is due to the fact that its atoms are not ordered in a tidy repeating crystalline structure, but rather are jumbled up into an atomic omnishambles.
But the amorphous ice that the team has been creating through tests with ball milling is unlike any amorphous ice that has ever been observed.

Typically, amorphous ice has a density between 0.94 grams per cubic centimeter and 1.13 grams per cubic centimeter. The new ice is quite close to water, which has a density of 1 gram per cubic centimeter, at 1.06 grams per cubic centimeter.

Researchers are developing quantum-proof encryption methods that would be much more difficult for quantum computers to crack. Stay tuned for updates on this important field of study!

Exciting Breakthrough in the Search for Alien Life with AI Assistance!
Astronomers using artificial intelligence have identified 8 radio signals that are believed to be of extraterrestrial origin. The Breakthrough Listen project, which is a global effort to find evidence of alien life, has utilized cutting-edge AI algorithms to analyze data from the radio telescope at Green Bank Observatory in West Virginia.
The signals, known as Fast Radio Bursts (FRBs), are extremely brief and have not been able to be explained by any known natural phenomenon. This has led scientists to believe that these signals could be coming from intelligent civilizations in other galaxies.
The AI algorithms used in the project were able to analyze vast amounts of data in a short amount of time and identify patterns that were previously missed. This is a significant step forward in the search for extraterrestrial life and is further proof that AI can play a crucial role in scientific breakthroughs.
This discovery has reignited the excitement and speculation surrounding the possibility of finding alien life. While more research and investigation is required to confirm the origin of these signals, this is an exciting development in the search for extraterrestrial life and a testament to the power of AI technology.

Stay tuned with @science for further updates as the Breakthrough Listen project continues its efforts to find evidence of life beyond our planet!
