A groundbreaking mathematical equation that could transform medical procedures, natural gas extraction, and plastic packaging production in the future has been discovered.
The new equation, developed by scientists at the University of Bristol, indicates that diffusive movement through permeable material can be modeled exactly for the very first time. It comes a century after world-leading physicists Albert Einstein and Marian von Smoluchowski derived the first diffusion equation, and marks important progress in representing motion for a wide range of entities from microscopic particles and natural organisms to man-made devices.
Until now, scientists looking at particle motion through porous materials, such as biological tissues, polymers, various rocks and sponges have had to rely on approximations or incomplete perspectives.

While business transformation has always been critical to staying relevant and competitive, global disruptions brought on by the COVID-19 pandemic created an urgency to accelerate innovation to keep pace with market conditions and changes in customer demand. In fact, many digitally transformed companies have not only survived — they’ve thrived.
According to a 2021 McKinsey Survey, top-performing companies now obtain a larger share of their sales from products or services that didn’t exist just one year ago. These companies are making more aggressive plans to differentiate themselves with technology, and some are preparing to reinvent their value proposition altogether.
Tissue engineering and stem cells.
A series of talks on stem cells and tissue engineering.
In recent years, roboticists and material scientists worldwide have been trying to create artificial systems that resemble human body parts and reproduce their functions. These include artificial skins, protective layers that could also enhance the sensing capabilities of robots.
Researchers at Donghua University in China and the Jülich Centre for Neutron Science (JCNS) in Germany have recently developed a new and highly promising artificial ionic skin based on a self-healable elastic nanomesh, an interwoven structure that resembles human skin. This artificial skin, introduced in a paper published in Nature Communications, is soft, fatigue-free and self-healing.
“As we know, the skin is the largest organ in the human body, which acts as both a protective layer and sensory interface to keep our body healthy and perceptive,” Shengtong Sun, one of the researchers who carried out the study, told TechXplore. “With the rapid development of artificial intelligence and soft robotics, researchers are currently trying to coat humanoid robots with an ‘artificial skin’ that replicates all the mechanical and sensory properties of human skin, so that they can also perceive the everchanging external environment like us.”
A year back and bodily function improves, and it’s a shot rather than transfusion as needed from other plasma treatments.
Researchers have found that intramuscular injections of plasma concentrate made from human umbilical cord blood improve various health biomarkers and decrease biological age in elderly people [1].
Circulating proteins have a significant impact on our health, and blood plasma transfusion is increasingly used against inflammatory conditions as well as some autoimmune and genetic diseases [2]. Basically, plasma transfusion enables physicians to alter the concentration of interesting molecules in the blood.
In recent years, Michael and Irina Conboy, along with other researchers, have experimented with blood/plasma exchange in the context of longevity [3]. Their continuing research has shown that heterochronic parabiosis (blood exchange between old and young animals), as well as plasma transfusion and even dilution of old plasma [4], alleviate various aspects of aging and decrease biological age as measured by methylation clocks.
Glioblastoma is one of the most aggressive types of brain cancer known to man. For many, the chance of survival is often low. However, a new type of brain tumor therapy could help change things for the better. The therapy, which relies on destroying the “power source” of the cancer, has shown considerable success in mice. The scientists are hopeful it will work the same in humans.
The new therapy hopes to destroy the “power source” of glioblastoma tumors. A new study led by Israeli scientists shows that glioblastoma relies on specific brain cells to fuel the growth of its tumors. As a result, scientists began to look at ways to treat cancer by removing those cells instead. The new brain tumor therapy could completely starve out the cancer cells, allowing patients to enter remission.
Normally doctors would use chemotherapy to target the tumors directly. However, by removing brain cells called Astrocytes, scientists found they could starve out glioblastoma tumors in mice. Further, the tumors remained gone for as long as the astrocytes were repressed. And, even when they stopped suppressing, Dr. Lior Mayo, lead author on the study, says that 85 percent of mice stayed in remission.

At its height, the Roman Empire was home to about 30% of the world’s population, and in many ways the pinnacle of human advancement. Rome became the first city in history to reach one million inhabitants and was a center of technological, legal, and economic progress. An empire impossible to topple, stable and rich and powerful.
Until it wasn’t anymore. First slowly then suddenly, the most powerful civilization on earth collapsed. If this is how it has been over the ages, what about us today? Will we lose our industrial technology, and with that our greatest achievements, from one dollar pizza to smartphones or laser eye surgery? Will all this go away too?
