Proteins are essential to cells, carrying out complex tasks and catalyzing chemical reactions. Scientists and engineers have long sought to harness this power by designing artificial proteins that can perform new tasks, like treat disease, capture carbon or harvest energy, but many of the processes designed to create such proteins are slow and complex, with a high failure rate.

In a breakthrough that could have implications across the healthcare, agriculture, and energy sectors, a team lead by researchers in the Pritzker School of Molecular Engineering at the University of Chicago has developed an artificial intelligence-led process that uses big data to design new proteins.

By developing machine-learning models that can review protein information culled from genome databases, the researchers found relatively simple design rules for building artificial proteins. When the team constructed these artificial proteins in the lab, they found that they performed chemical processes so well that they rivaled those found in nature.

The European Food Safety Authority has taken in more than 156 innovative food applications for substances such as apple cell cultures and mung bean proteins since January 2018, when new EU legislation took effect, aiming to make it easier for businesses to bring their unusual products to market. Of those 156114 are still under consideration, 39 were approved and three were rejected, officials said.

More products have been submitted for approval since 2018 than in prior 14 years combined.

MIT anthropologist Amy Moran-Thomas reflects on the deep connection between planetary and human well-being.

When anthropologist Amy Moran-Thomas first went to Belize to begin ethnographic research in 2008, she planned to chronicle human health concerns, focusing on diabetes. Then she learned that local diets contributing to such chronic conditions were changing, in part due to losses in ocean food webs, and kept hearing stories about how local plants were in trouble.

“Listening and trying to learn from what people were saying, over the years I came to see human health and planetary health as deeply interconnected,” says Moran-Thomas, the Morrison Hayes Career Development Associate Professor of Anthropology at MIT. “When I think of health now, I think of disarray in bigger ecosystems and infrastructures that’s also landing in human bodies.”

From the outside, VertiVegies looked like a handful of grubby shipping containers put side by side and drilled together. A couple of meters in height, they were propped up on a patch of concrete in one of Singapore’s nondescript suburbs. But once he was inside, Ankesh Shahra saw potential. Huge potential.

Shahra, who wears his dark hair floppy and his expensive-looking shirts with their top button casually undone, had a lot of experience in the food industry. His grandfather had founded the Ruchi Group, a corporate powerhouse in India with offshoots in steel, real estate, and agriculture; his father had started Ruchi Soya, a $3 billion oilseed processor that had been Shahra’s training ground.

AUSTIN, Texas — Producing clean water at a lower cost could be on the horizon after researchers from The University of Texas at Austin and Penn State solved a complex problem that had baffled scientists for decades, until now.

Desalination membranes remove salt and other chemicals from water, a process critical to the health of society, cleaning billions of gallons of water for agriculture, energy production and drinking. The idea seems simple — push salty water through and clean water comes out the other side — but it contains complex intricacies that scientists are still trying to understand.

The research team, in partnership with DuPont Water Solutions, solved an important aspect of this mystery, opening the door to reduce costs of clean water production. The researchers determined desalination membranes are inconsistent in density and mass distribution, which can hold back their performance. Uniform density at the nanoscale is the key to increasing how much clean water these membranes can create.

News Americas, MIAMI, FL, Fri. Mar. 22018: A form of calculation that made the ancient Mayans such a successful race has been rediscovered by academics in Mexico, and is now being taught to the descendants of the long-lost culture.

Mayan math, an ancient mathematical method invented by the Mayans, has made the mathematicians of the long-lost civilization that built Chichen Itza in the jungles of the Yucatan Peninsula some of the most advanced of their time.

Now students in the remote village of Kanxoc are learning the ancient method and doing simple arithmetic with beans, sticks and pasta shells on a simple grid.

A desalination membrane acts as a filter for salty water: push the water through the membrane, get clean water suitable for agriculture, energy production and even drinking. The process seems simple enough, but it contains complex intricacies that have baffled scientists for decades—until now.

Researchers from Penn State, The University of Texas at Austin, Iowa State University, Dow Chemical Company and DuPont Water Solutions published a key finding in understanding how membranes actually filter minerals from water, online today (Dec. 31) in Science. The article will be featured on the print edition’s cover, to be issued tomorrow (Jan. 1).

“Despite their use for many years, there is much we don’t know about how water filtration membranes work,” said Enrique Gomez, professor of chemical engineering and materials science and engineering at Penn State, who led the research. “We found that how you control the density distribution of the membrane itself at the nanoscale is really important for water-production performance.”

HONG KONG—China is aggressively advancing alternative theories about the source of the coronavirus that causes Covid-19, muddying the waters as the World Health Organization prepares to launch a long-awaited investigation into the origins of the pandemic. In recent weeks, Chinese state media, often suggesting the virus came from outside China, have seized on a series of recent studies that show it was spreading outside the country earlier than first assumed. Government officials have also pushed the theory that the virus could have hitched a ride into the central Chinese city of Wuhan on frozen-food imports. After outbreaks in multiple Chinese cities in recent months including Beijing, Shanghai, Tianjin and elsewhere, authorities pointed to frozen-food packaging as the potential origin. https://www.wsj.com/articles/china-pushes-alternative-theories-about-origin-of-covid-19-11607445463
