Scientists develop novel technique to grow meat in the lab using magnetic field

Posted by in categories: bioengineering, biotech/medical, genetics

Scientist from the National University of Singapore (NUS) have found a novel way of growing cell-based meat by zapping animal cells with a magnet. This new technique simplifies the production process of cell-based meat by reducing reliance on animal products, and it is also greener, cleaner, safer and more cost-effective.

Cultured is an alternative to animal farming with advantages such as reducing and the risk of transmitting diseases in animals. However, the current method of producing cultured meat involves using other , which largely defeats the purpose, or drugs to stimulate the growth of the meat.

To cultivate cell-based meat, are fed animal serum—usually fetal bovine serum (FBS), which is a mixture harvested from the blood of fetuses excised from pregnant cows slaughtered in the dairy or meat industries—to help them grow and proliferate. This is a critical, yet cruel and expensive, step in the current cell-based meat production process. Ironically, many of these molecules come from the muscles within the slaughtered animal, but scientists did not know how to stimulate their release in production scale bioreactors. Other methods to promote are using drugs or relying on genetic engineering.

Scientists bring cultured meat closer to your kitchen table

Posted by in categories: biological, particle physics

Researchers at UCLA have created an edible particle that helps make lab-grown meat, known as cultured meat, with more natural muscle-like texture using a process that could be scaled up for mass production.

Led by Amy Rowat, who holds UCLA’s Marcie H. Rothman Presidential Chair of Food Studies, the researchers have invented edible particles called microcarriers with customized structures and textures that help precursor grow quickly and form muscle-like tissues. Edible microcarriers could reduce the expense, time, and waste required to produce cultured with a that appeals to consumers. The results are published in the journal Biomaterials.

“Animal cells that can be coaxed to form tissues similar to meats could offer a protein source to a world facing caused by threats ranging from epidemics to ,” said Rowat, who is an associate professor of integrative biology and physiology at the UCLA College. “Cultured are not yet on the market in the U.S. and strategies to enable are still emerging.”

Swimming nanorobots treat deadly pneumonia in mice

Posted by in categories: materials, robotics/AI

Nanoengineers at the University of California San Diego have developed microscopic robots, called microrobots, that can swim around in the lungs, deliver medication and be used to clear up life-threatening cases of bacterial pneumonia.

In mice, the microrobots safely eliminated pneumonia-causing bacteria in the lungs and resulted in 100% survival. By contrast, untreated mice all died within three days after infection.

The results are published Sept. 22 in Nature Materials.

Powerful hurricanes get second wind in Europe

Posted by in category: climatology

Stronger hurricanes that are re-energized by jet stream winds are twice as likely to cross the Atlantic and wreak havoc in Europe than weaker ones, new research has found.

Atlantic hurricanes generate international attention because of the destruction they can cause across North America and the Caribbean. Just days ago, ex-hurricane Fiona impacted Canada as one of their strongest storms on record. While lesser-known, these cyclones can also wreak havoc in Europe.

The question of why some hurricanes make it to Europe as ex-hurricanes while others don’t has been unclear. The scientists investigated this question by studying 180 ex-hurricanes over a 40-year period, finding that stronger hurricanes are far more likely to reach Europe, and that those encountering strong jet stream winds often re-intensify, helping them to move further east.

Tiny sea creature’s genes shed light on evolution of immunity

Posted by in categories: biotech/medical, evolution

How a tiny marine invertebrate distinguishes its own cells from competitors’ bears striking similarities to the human immune system, according to a new study led by University of Pittsburgh School of Medicine researchers.

The findings, published now in Proceedings of the National Academy of Sciences, suggest that the building blocks of our immune system evolved much earlier than previously thought and could help improve understanding of transplant rejection, one day guiding development of new immunotherapies.

“For decades, researchers have wondered whether self-recognition in a marine creature called Hydractinia symbiolongicarpus was akin to the processes that control whether a piece of skin can be successfully grafted from one person to another,” said senior author Matthew Nictora, Ph.D., assistant professor of surgery and immunology at the Thomas E. Starzl Transplantation Institute. “Our study shows for the first time that a special group of proteins called the immunoglobulin superfamily— which are important for adaptive immunity in mammals and other vertebrates—are found in such a distantly-related animal.”

Exotic electronic effect found in 2D topological material

Posted by in categories: particle physics, quantum physics, robotics/AI

Jülich researchers have been able to demonstrate an exotic electronic state, so-called Fermi Arcs, for the first time in a 2D material. The surprising appearance of Fermi arcs in such a material provides a link between novel quantum materials and their respective potential applications in a new generation of spintronics and quantum computing. The results have recently been published in Nature Communications.

The newly detected Fermi arcs represent special—arc-like—deviations from the so-called Fermi surface. The Fermi surface is used in condensed matter physics to describe the momentum distribution of electrons in a metal. Normally, these Fermi surfaces represent closed surfaces. Exceptions such as the Fermi arcs are very rare and often are associated with exotic properties like superconductivity, negative magnetoresistance and anomalous quantum transport effects.

Today’s technology challenge is to develop the “on-demand” control of physical properties in materials. However, such experimental tests have been largely limited to bulk materials and are key grand challenges in condensed matter science. With its groundbreaking paradigm, the findings present a promising new frontier for quantum control of topological states in low-dimensional systems by external means—the that offers unprecedented capabilities on 2D materials for as well as future information processing.

Caltech-led Research Team Finds Traditional Computers Can Solve Some Quantum Problems

Posted by in categories: chemistry, quantum physics, robotics/AI

PRESS RELEASE — There has been a lot of buzz about quantum computers and for good reason. The futuristic computers are designed to mimic what happens in nature at microscopic scales, which means they have the power to better understand the quantum realm and speed up the discovery of new materials, including pharmaceuticals, environmentally friendly chemicals, and more. However, experts say viable quantum computers are still a decade away or more. What are researchers to do in the meantime?

A new Caltech-led study in the journal Science describes how machine learning tools, run on classical computers, can be used to make predictions about quantum systems and thus help researchers solve some of the trickiest physics and chemistry problems. While this notion has been shown experimentally before, the new report is the first to mathematically prove that the method works.

“Quantum computers are ideal for many types of physics and materials science problems,” says lead author Hsin-Yuan (Robert) Huang, a graduate student working with John Preskill, the Richard P. Feynman Professor of Theoretical Physics and the Allen V. C. Davis and Lenabelle Davis Leadership Chair of the Institute for Quantum Science and Technology (IQIM). “But we aren’t quite there yet and have been surprised to learn that classical machine learning methods can be used in the meantime. Ultimately, this paper is about showing what humans can learn about the physical world.”
