Protecting crops through nanotechnology in Southeast Asia

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

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

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

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.

Breakthrough could see robots with ‘fingertips’ as sensitive as humans

Researchers have overcome a major challenge in biomimetic robotics by developing a sensor that, assisted by AI, can slide over braille text, accurately reading it at twice human speed. The tech could be incorporated into robot hands and prosthetics, providing fingertip sensitivity comparable to humans.

Human fingertips are incredibly sensitive. They can communicate details of an object as small as about half the width of a human hair, discern subtle differences in surface textures, and apply the right amount of force to grip an egg or a 20-lb (9 kg) bag of dog food without slipping.

As cutting-edge electronic skins begin to incorporate more and more biomimetic functionalities, the need for human-like dynamic interactions like sliding becomes more essential. However, reproducing the human fingertip’s sensitivity in a robotic equivalent has proven difficult despite advances in soft robotics.

How Indian Farmers Are Using AI To Increase Crop Yield

The Telangana state government in South India, in collaboration with various agricultural aid organizations and technology companies, launched a groundbreaking project known as “Saagu Baagu.” This initiative focused on assisting 7,000 chilli farmers with AI-powered tools, marking a significant step…

Saagu Baagu shows AI’s growing role in agriculture, helping developing-world farmers achieve sustainable and profitable practices.

Watch SpaceX launch a Northrop Grumman resupply mission to the ISS

SpaceX is teaming up with Northrop Grumman today to deliver more than 8,000 pounds of cargo, fresh food and scientific experiments to astronauts on the International Space Station.

The NG-20 resupply mission will take off from the Space Force’s Cape Canaveral in Florida on a SpaceX Falcon 9 rocket at around 12:07 p.m. EST. Northrop’s Cygnus cargo capsule will arrive at the International Space Station on February 1.

Northrop has been launching Cygnus to the ISS for resupply missions using its own Antares rocket since 2013, with the exception of just two missions that used a United Launch Alliance Atlas 5. But Northrop retired that version of Antares last year, and the next version — an all-American launch vehicle called Antares 330, which it is developing with Firefly Aerospace — will not be ready to fly until around mid-2025.

Watch this self-eating rocket prototype engine consume itself then explode (video)

Would come in handy! More room for payloads too!

British researchers have tested a prototype self-eating rocket that could pave the way for cheaper launches of small satellites and would leave no debris behind.

The concept rocket engine, called Ouroborous-3 after the ancient mythical creature that eats its own tail, was developed by a team of researchers at the University of Glasgow in the U.K.
