Crafting organic containers by shaping the gourd fruit.
Take a sip of coffee from a cup that’s literally GROWN in nature! The gourd fruit can fill any form, making them perfect for crafting containers to hold food and liquids, no plastic needed!
Will this enable people to make super strong concrete the future? 🙂
Scientists in Japan have found a rare mineral in concrete walls of a decommissioned power plant, which is as strong as concrete the Romans used.
Using ocean/sea waves for power. 😃
This is the Eco Wave Power, an innovative and affordable technology that produces clean, renewable energy from ocean waves. (More info: https://youtu.be/BrDua3j1U3M)
Stem cells from fat. 😃
A new type of stem cell—that is, a cell with regenerative abilities—could be closer on the horizon, a new study led by UNSW Sydney shows.
The stem cells (called induced multipotent stem cells, or iMS) can be made from easily accessible human cells—in this case, fat—and reprogrammed to act as stem cells.
Not all appears as it would seem in the Whirlpool galaxy. One of the best-studied spiral galaxies and a delight to amateur astronomers, Messier 51, as it’s officially named, is influenced by powerful, invisible forces.
Located 31 million light-years away in the constellation Canes Venatici, the galaxy’s arms are strikingly visible as they reach out along the central spine structure, displaying swirling clouds of gas and dust that are massive star-making factories. But new observations by NASA ’s Stratospheric Observatory for Infrared Astronomy, or SOFIA, presented at this week’s 237th meeting of the American Astronomical Society, shows a more complicated picture.
Radio telescopes previously detected neatly-drawn magnetic fields throughout the length of the galaxy’s massive arms. But under SOFIA’s infrared gaze for the first time those lines give way to a chaotic scene in the outer spiral arms. Using a far-infrared camera and imaging polarimeter instrument called the High-Resolution Airborne Wideband Camera, or HAWC+, researchers found that the magnetic fields in the outskirts of the galaxy no longer follow the spiral structure and are instead distorted.
To understand ourselves and our place in the universe, “we should have humility but also self-respect,” the physicist writes in a new book.
In the spring of 1970, colleges across the country erupted with student protests in response to the Vietnam War and the National Guard’s shooting of student demonstrators at Kent State University. At the University of Chicago, where Frank Wilczek was an undergraduate, regularly scheduled classes were “improvised and semivoluntary” amid the turmoil, as he recalls.
It was during this turbulent time that Wilczek found unexpected comfort, and a new understanding of the world, in mathematics. He had decided to sit in on a class by physics professor Peter Freund, who, with a zeal “bordering on rapture,” led students through mathematical theories of symmetry and ways in which these theories can predict behaviors in the physical world.

While today’s computers—referred to as classical computers—continue to become more and more powerful, there is a ceiling to their advancement due to the physical limits of the materials used to make them. Quantum computing allows physicists and researchers to exponentially increase computation power, harnessing potential parallel realities to do so.
Quantum computer chips are astoundingly small, about the size of a fingernail. Scientists have to not only build the computer itself but also the ultra-protected environment in which they operate. Total isolation is required to eliminate vibrations and other external influences on synchronized atoms; if the atoms become ‘decoherent’ the quantum computer cannot function.
“You need to create a very quiet, clean, cold environment for these chips to work in,” says quantum computing expert Vern Brownell. The coldest temperature possible in physics is-273.15 degrees C. The rooms required for quantum computing are-273.14 degrees C, which is 150 times colder than outer space. It is complex and mind-boggling work, but the potential for computation that harnesses the power of parallel universes is worth the chase.

Scientists in Florida have developed process to create methane using aerobic digester.
The result was a bizarre, Lego-like human tissue that replicates the basic circuits behind how we decide to move. Without external prompting, when churned together like ice cream, the three ingredients physically linked up into a fully functional circuit. The 3D mini-brain, through the information highway formed by the artificial spinal cord, was able to make the lab-grown muscle twitch on demand.
In other words, if you think isolated mini-brains—known formally as brain organoids—floating in a jar is creepy, upgrade your nightmares. The next big thing in probing the brain is assembloids—free-floating brain circuits—that now combine brain tissue with an external output.
The end goal isn’t to freak people out. Rather, it’s to recapitulate our nervous system, from input to output, inside the controlled environment of a Petri dish. An autonomous, living brain-spinal cord-muscle entity is an invaluable model for figuring out how our own brains direct the intricate muscle movements that allow us stay upright, walk, or type on a keyboard.
