AI system finds, moves items in constricted regions

Posted by in categories: food, policy, robotics/AI

Artificial intelligence is being applied to virtually every aspect of our work and recreational lives. From determining calculations for the construction of towering skyscrapers to designing and building cruise ships the size of football fields, AI is increasingly playing a key role in the most massive projects.

But sometimes, all we want to do is move a can of beans.

Is coronavirus accelerating the growth of plant-based meat?

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

Sales for the category have exploded as the pandemic disrupts business as usual. Is this because people are turning away from animal-based eating, or is it keeping with the segment’s trends?

These Ants Suit Up in a Protective ‘Biomineral Armor’ Never Seen Before in Insects

Posted by in category: food

Scientists find that A. echinatior ants have biomineral armour to help them in battle with other ants and protect them from pathogens. 😃


Ants are pretty organised little creatures. Highly social insects, they know how to forage, build complicated nests, steal your pantry snacks, and generally look after the queens and the colony, all by working together.

Leaf-cutter ants turn that cooperation up several notches. Leaf-cutter ant colonies like Acromyrmex echinatior can contain millions of ants, split into four castes that all have different roles to maintain a garden of fungus that the ants eat.

Sestrin makes fruit flies live longer

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

10% longer.


Reduced food intake, known as dietary restriction, leads to a longer lifespan in many animals and can improve health in humans. However, the molecular mechanisms underlying the positive effects of dietary restriction are still unclear. Researchers from the Max Planck Institute for Biology of Aging have now found one possible explanation in fruit flies: they identified a protein named Sestrin that mediates the beneficial effects of dietary restriction. By increasing the amount of Sestrin in flies, researchers were able to extend their lifespan and at the same time these flies were protected against the lifespan-shortening effects of a protein-rich diet. The researchers could further show that Sestrin plays a key role in stem cells in the fly gut thereby improving the health of the fly.

The health benefits of have long been known. Recently, it has become clear that restriction of certain food components, especially proteins and their individual building blocks, the , is more important for the organism’s response to dietary restriction than general calorie reduction. On the , one particular well-known signaling pathway, named TOR pathway, is important for longevity.

A ‘crisper’ method for gene editing in fungi

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

O,.o Circa 2019


CRISPR/Cas9 is now a household name associated with genetic engineering studies. Through cutting-edge research described in their paper published in Scientific Reports, a team of researchers from Tokyo University of Science, Meiji University, and Tokyo University of Agriculture and Technology, led by Dr Takayuki Arazoe and Prof Shigeru Kuwata, has recently established a series of novel strategies to increase the efficiency of targeted gene disruption and new gene “introduction” using the CRISPR/Cas9 system in the rice blast fungus Pyricularia (Magnaporthe) oryzae. These strategies include quicker (single-step) gene introduction, use of small homologous sequences, and bypassing of certain prerequisite host DNA “patterns” and host component modification.

The team led by Dr Arazoe and Prof Kuwata has devised simple and quick techniques for gene editing (target gene disruption, sequence substitution, and re-introduction of desired genes) using CRISPR/Cas9 in the rice blast fungus Pyricularia (Magnaporthe) oryzae, a type of filamentous fungus. Spurred on by encouraging results, the researchers surmise, “Plants and their pathogens are still coevolving in nature. Exploiting the mutation mechanisms of model pathogenic fungi as a genome editing technique might lead to the development of further novel techniques in genetic engineering.”

The working component of the CRISPR/Cas9 system binds to the target gene region (DNA) and causes a site-specific double-stranded break (DSB) in the DNA. Effective binding of this component requires a certain “motif” or “pattern” called the protospacer-adjacent motif (PAM), which follows downstream of the target gene region.

CRISPR-edited bananas immune to killer pathogens advance toward commercialization in Africa

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

For more than two decades, I have been working to improve several staple food crops in Africa, including bananas, plantains, cassavas and yams. As principal scientist and a plant biotechnologist at the International Institute for Tropical Agriculture in Nairobi, I aim to develop varieties that are resistant to pests and diseases such as bacterial wilt, Fusarium wilt (caused by the fungus F. oxysporum) and banana streak virus.

[Editor’s note: Abdullahi Tsanni is a freelance science journalist based in Abuja, Nigeria.]

In 2011, my team and I created a set of tools, the only one of its kind in Africa, for changing DNA sequences so that we could develop genetically modified and genome-edited products in sub-Saharan Africa. In 2018, we pioneered the first application of CRISPR gene-editing technology to deactivate banana streak virus in plantains. This technology overcame a major hurdle in banana breeding on the continent, and is the first reported successful use of genome editing to improve bananas.

High-Efficiency CRISPR/Cas9-Mediated Gene Editing in Honeybee (Apis mellifera) Embryos

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

The honeybee (Apis mellifera) is an important insect pollinator of wild flowers and crops, playing critical roles in the global ecosystem. Additionally, the honeybee serves as an ideal social insect model. Therefore, functional studies on honeybee genes are of great interest. However, until now, effective gene manipulation methods have not been available in honeybees. Here, we reported an improved CRISPR/Cas9 gene-editing method by microinjecting sgRNA and Cas9 protein into the region of zygote formation within 2 hr after queen oviposition, which allows one-step generation of biallelic knockout mutants in honeybee with high efficiency. We first targeted the Mrjp1 gene. Two batches of honeybee embryos were collected and injected with Mrjp1 sgRNA and Cas9 protein at the ventral cephalic side and the dorsal posterior side of the embryos, respectively. The gene-editing rate at the ventral cephalic side was 93.3%, which was much higher than that (11.8%) of the dorsal-posterior-side injection. To validate the high efficiency of our honeybee gene-editing system, we targeted another gene, Pax6, and injected Pax6 sgRNA and Cas9 protein at the ventral cephalic side in the third batch. A 100% editing rate was obtained. Sanger sequencing of the TA clones showed that 73.3% (for Mrjp1) and 76.9% (for Pax6) of the edited current-generation embryos were biallelic knockout mutants. These results suggest that the CRISPR/Cas9 method we established permits one-step biallelic knockout of target genes in honeybee embryos, thereby demonstrating an efficient application to functional studies of honeybee genes. It also provides a useful reference to gene editing in other insects with elongated eggs.
