New method makes starch from CO₂ faster than plants can

Posted by in categories: chemistry, food, sustainability

Feeding the world uses enormous amounts of land, water, fertilizer, pesticide, and fuel. In a step towards a more sustainable solution, researchers have designed a method to make starches from carbon dioxide more efficiently than plants do (Science 2,021 DOI: 10.1126/science.abh4049).

The new technique, which relies on chemical catalysts and a curated combination of natural and engineered enzymes, converts CO2 to starch 8.5 times as efficiently as corn plants can.


The advance hints at sustainable, efficient factory production of food and industrial chemicals by.

What Longevity Diet do Experts Eat?

Posted by in categories: food, life extension, lifeboat

We interviewed four longevity experts (including several Lifeboat Foundation board members) to learn how they think about their diets. I was particularly struck by how different they all were (except almost all of them fasted)!


Food.

In all our research into longevity so far, from quantifying how we sleep to exploring the science behind whether human life extension is possible, nutrition has remained the most controversial and confusing subject that we’ve covered. For example, when we surveyed 101 of our readers on their longevity diet, we got 101 very different answers. There is little consensus on what the perfect life extension diet should look like.

Does eating healthy prevent people from getting, dying from COVID?

Posted by in categories: biotech/medical, food, information science

We know that a daily diet that includes lots of fruit and vegetables is healthier, but now it seems that it can also help prevent one from being infected with COVID-19.

A new study from Boston published in the journal Gut reports that consuming healthy food like produce may lower the risk of contracting the virus, in addition to lowering the severity of symptoms if one is infected. Although doctors have stated that metabolic conditions including obesity and type 2 diabetes can cause severe coronavirus complications, this study is among the first to add nutrition to the equation.


A new study claims that one-third of coronavirus cases could have been avoided if people had healthier eating habits.

Machine learning uncovers ‘genes of importance’ in agriculture and medicine

Posted by in categories: biotech/medical, food, health, robotics/AI

“We show that focusing on genes whose expression patterns are evolutionarily conserved across species enhances our ability to learn and predict ‘genes of importance’ to growth performance for staple crops, as well as disease outcomes in animals,” explained Gloria Coruzzi, Carroll & Milton Petrie Professor in NYU’s Department of Biology and Center for Genomics and Systems Biology and the paper’s senior author.


Machine learning can pinpoint “genes of importance” that help crops to grow with less fertilizer, according to a new study published in Nature Communications. It can also predict additional traits in plants and disease outcomes in animals, illustrating its applications beyond agriculture.

Using to predict outcomes in agriculture and medicine is both a promise and challenge for . Researchers have been working to determine how to best use the vast amount of genomic data available to predict how organisms respond to changes in nutrition, toxins, and pathogen exposure—which in turn would inform crop improvement, disease prognosis, epidemiology, and public health. However, accurately predicting such complex outcomes in agriculture and medicine from genome-scale information remains a significant challenge.

Mice Treated with This Cytokine Lose Weight

Posted by in categories: biotech/medical, food

PHILADELPHIA – Treating obese mice with the cytokine known as TSLP led to significant abdominal fat and weight loss compared to controls, according to new research published Thursday in Science from researchers in the Perelman School of Medicine at the University of Pennsylvania. Unexpectedly, the fat loss was not associated with decreased food intake or faster metabolism. Instead, the researchers discovered that TSLP stimulated the immune system to release lipids through the skin’s oil-producing sebaceous glands.

“This was a completely unforeseen finding, but we’ve demonstrated that fat loss can be achieved by secreting calories from the skin in the form of energy-rich sebum,” said principal investigator Taku Kambayashi, MD, PhD, an associate professor of Pathology and Laboratory Medicine at Penn, who led the study with fourth-year medical student Ruth Choa, PhD. “We believe that we are the first group to show a non-hormonal way to induce this process, highlighting an unexpected role for the body’s immune system.”

The animal model findings, Kambayashi said, support the possibility that increasing sebum production via the immune system could be a strategy for treating obesity in people.

The microbial molecule that turns plants into zombies

Posted by in categories: biotech/medical, food, life extension

A newly discovered manipulation mechanism used by parasitic bacteria to slow down plant aging, may offer new ways to protect disease-threatened food crops.

Parasites manipulate the organisms they live off to suit their needs, sometimes in drastic ways. When under the spell of a parasite, some plants undergo such extensive changes that they are described as “zombies”. They stop reproducing and serve only as a habitat and host for the parasitic pathogens.

Until now, there’s been little understanding of how this happens on a molecular and mechanistic level.

Plants as mRNA Factories for Edible Vaccines

Posted by in categories: biotech/medical, food

University of California-Riverside (UCR) researchers say they are studying whether they can turn edible plants like lettuce into mRNA vaccine factories.

One of the challenges with this new technology is that it must be kept cold to maintain stability during transport and storage. If this new project is successful, plant-based mRNA vaccines, which can be eaten, could overcome this challenge with the ability to be stored at room temperature.

The project’s goals, made possible by a $500,000 grant from the National Science Foundation, are threefold: showing that DNA containing the mRNA vaccines can be successfully delivered into the part of plant cells where it will replicate, demonstrating the plants can produce enough mRNA to rival a traditional shot, and finally, determining the right dosage.

New technology makes it possible to see clearly through murky water

Posted by in categories: food, particle physics, sustainability

Researchers have developed a new method that can automatically produce clear images through murky water. The new technology could be useful for searching for drowning victims, documenting submerged archaeological artifacts and monitoring underwater farms.

Imaging clearly underwater is extremely challenging because the and the particles in it tend to scatter light. But, because scattered light is partially polarized, imaging using a camera that is sensitive to polarization can be used to suppress scattered light in underwater .

“Our new method overcomes the limitations of traditional polarimetric underwater imaging, laying the groundwork for taking this method out of the lab and into the field,” said research team leader Haofeng Hu from Tianjin University in China. “Unlike previous methods, there’s no requirement for the image to include a background area to estimate the backscattered light.”
