Scientists gene-edit tomatoes to need less water

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

Climate change and increasingly extreme weather conditions are predicted to wreak havoc with humanity’s food security. But hopefully, at least tomatoes will stay safe.

Researchers from Tel Aviv University have succeeded in cultivating tomato varieties that consume less water as they grow without compromising on yield, quality or taste, using CRISPR genome editing technology.

Their study, which contributes to growing efforts to ensure food security in a world of diminishing freshwater resources, was recently published in the journal PNAS.

SynMoss project grows moss with partially synthetic genes

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

A Chinese team of life scientists, microbiologists, plant researchers and seed designers has developed a way to grow engineered moss with partially synthetic genes. In their project, reported in the journal Nature Plants, the group engineered a moss that is one of the first living things to have multiple cells carrying a partially artificial chromosome.

Several research projects have been working toward the goal of creating plants with synthetic —such plants could be programmed to produce more food, for example, or more oxygen, or to pull more from the air. Last year, one team of researchers developed a way to program up to half of the genome of yeast cells using synthetic genes.

In this new effort, the team in China upped the ante by replacing natural genes with genes created in a lab—moss is far more genetically complex than yeast. They call their project SynMoss.

Meatball made from woolly mammoth unveiled in the Netherlands

Posted by in category: food

An Australian cultured meat startup has “resurrected” the woolly mammoth — in the hope that people will think about eating it.

The challenge: Our traditional way of producing meat — by raising and slaughtering animals — is both bad for the environment and arguably unethical, yet demand for meat continues to increase.

Dexa aims to get more out of podcasts with AI-powered search

Posted by in categories: food, robotics/AI

If you listen to a lot of podcasts, there is a chance you might remember funny tidbits and are wondering… “Wait, who talked about eating fries with sriracha again?” or more serious questions. To look for the answers, you have to first find the podcast and then search through their transcripts. Dexa is trying to make podcast search easier by leveraging AI.

The tool lets you ask questions about a single podcast, like Andrew Humberman’s Huberman Lab podcast in the screenshot below, or query all the podcasts in Dexa’s database — there are currently more than 120 with more being added. The search results will give you an AI-generated summary of the answer along with pointers to podcasts where the participant discussed the topic.

For instance, you can ask questions like “What’s the best way to get more sleep?” and find answers to that from Dexa’s podcast library with timestamped links to those conversations. You can also @mention a specific podcast to narrow down your search results.

New Model for Norovirus Offers Promising Path Towards Countermeasure Development

Posted by in categories: biotech/medical, food, genetics, health

Norovirus, a highly infectious virus that is the leading cause of diarrhea and vomiting in the U.S., has no approved therapeutics or vaccines to prevent its miserable effects. This is partly due to a lack of reliable animal models to study norovirus infection and predict how effective interventions would be in people. To solve this, NIAID scientists have developed an animal model to study human norovirus infection that could help facilitate the development of new vaccines and therapeutics to treat norovirus infection. Findings from this research were published Feb. 6 in Nature Microbiology.

Human norovirus causes illness in tens of millions of people in the U.S. each year and, in some cases, can result in hospitalization and even death. It is easily spread when people ingest foods, drinks or particles from surfaces contaminated by virus from the stool or vomit of an infected individual. Noroviruses are genetically diverse, with different genogroups—groups characterized by genetic similarity—of the virus infecting different species of animals. Several genogroups of noroviruses infect people without similarly infecting animals. This has led to difficulties in establishing an animal model for human norovirus infection.

Following up on earlier evidence that rhesus macaque monkeys could develop norovirus infections, a team of researchers led by scientists at NIAID’s Vaccine Research Center set out to determine whether macaques could serve as an effective animal model for the human disease. The macaques were challenged with several genotypes of human noroviruses at once. Throughout the experiment, the animals were kept in biocontainment, and their health and behavior were carefully monitored. Levels of virus in the animals’ stool were measured, and antibodies against norovirus in the animals’ blood serum were analyzed. The researchers found that the macaques were susceptible to viral infection with at least two genotypes of norovirus, with similar antibody responses, shedding of virus in stool, and pathology as in human norovirus infection. Notably, the infections in the animals did not result in clinical symptoms, such as diarrhea and vomiting.

Protecting crops through nanotechnology in Southeast Asia

Posted by in categories: biotech/medical, food, nanotechnology

In a recent breakthrough, DNA sequencing technology has uncovered the culprit behind cassava witches’ broom disease: the fungus genus Ceratobasidium. The cutting-edge nanopore technology used for this discovery was first developed to track the COVID-19 virus in Colombia, but is equally suited to identifying and reducing the spread of plant viruses.

The findings, published in Scientific Reports, will help plant pathologists in Laos, Cambodia, Vietnam and Thailand protect farmers’ valued harvest.

“In Southeast Asia, most rely on cassava. Its starch-rich roots form the basis of an industry that supports millions of producers. In the past decade, however, cassava witches’ broom disease has stunted plants, reducing harvests to levels that barely permit affected farmers to make a living,” said Wilmer Cuellar, Senior Scientist at the Alliance of Bioversity and CIAT.

The Potential of Algae-Based Supplements in Nutritional Health

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

Algae provide a wide range of nutrients that are beneficial for health, including protein, sterols, and vitamins. Numerous health-promoting characteristics, including antioxidant and anti-proliferative actions in relation to algal phenolic and flavonoid concentrations, have been shown by scientific research 6–9. Produced for both humans and animals, algae and microalgae are often rich sources of fats (especially omega-3 fatty acids and carotenoids), carbohydrates, minerals, enzymes, hormones, and colors 10.

Health benefits supported by science

Algae have been shown to have multiple health benefits, including the ability to combat microbiological infections, hypertension, obesity, and diabetes, owing to their complex nutritional composition. As a result, the market for nutraceuticals generated from algae is growing quickly in the food supplement industry. A major factor in this has also been the idea of algae prebiotics and how they affect the gut microbiota 11.

Biotech is the new focus in U.S.-China tech rivalry

Posted by in categories: biotech/medical, economics, food, security

The need to quash outbreaks, quickly create medicines, stress-proof crops and fend off other 21st century threats is providing a lucrative arena for biotech companies to sell their services.

Why it matters: But the infrastructure to support such ambitions is increasingly recognized by the U.S., China and other countries as a linchpin of national security and economic strategy, putting it at the center of geopolitics.

Mathematical model reveals how a pit viper is able to find its dinner in the dead of night

Posted by in categories: food, mathematics

In the animal kingdom, there are many grand examples of species that make sense of their world by expertly deciphering even weak signals from their surroundings.

An eagle soaring above the ground spies a river fish down below, about to swallow a bug; a hungry black bear smells a morsel of food two miles away in a dense thicket; a duck-billed platypus, swimming in a freshwater creek, closes its eyes and detects the electric impulses of a tasty tadpole nearby.

Then there are the pit vipers.
