Gene-edited tomatoes could be a new source of vitamin D

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

Tomatoes gene-edited to produce vitamin D, the sunshine vitamin, could be a simple and sustainable innovation to address a global health problem.

Researchers used gene editing to turn off a specific molecule in the plant’s genome which increased provitamin D3 in both the fruit and leaves of tomato plants. It was then converted to vitamin D3 through exposure to UVB light.

Vitamin D is created in our bodies after skin’s exposure to UVB light, but the major source is food. This new biofortified crop could help millions of people with vitamin D insufficiency, a growing issue linked to higher risk of cancer, dementia, and many leading causes of mortality. Studies have also shown that vitamin D insufficiency is linked to increased severity of infection by Covid-19.

Space hotel with artificial gravity will be in orbit by 2025

Posted by in categories: food, space

If Earthly destinations are not enough to quench your wanderlust, a trip to a space hotel might get on your radar within the next few years. The designer of the Von Braun Space Station revealed numerous plans that detail the construction of a veritable resort in space.

Built by the Gateway Foundation, the world’s first space hotel will have gravity, bars, inviting interiors and full-fledged kitchens. They plan to have the station visited by about a 100 tourists per week by 2025.


The Von Braun Space Station, based on the concepts of a controversial scientist, is moving ahead with construction plans.

This Algae Powered a Computer for a Year With Just Water and Sunlight

Posted by in categories: computing, food, internet

In addition to being a simple power source built from readily available parts and materials, the system runs day and night (in contrast with solar power). The algae, the team thinks, overproduces food during the day, so it continues to happily munch away, and produce electricity, through the night. Although the paper addresses their findings from just that first six-month period, their algae-powered-computer has now been running continuously for a year (and counting).

It’s a pretty nifty trick, but some scaling is probably in order. The system produces a tiny amount of current. The chip, an Arm Cortex M0+ commonly used in Internet of Things applications, sips just 0.3 microwatts an hour to perform very basic calculations. As The Verge notes, if your average laptop uses around 100 watts an hour, you’d need millions of these algae energy harvesters just to check your email or zone out in a Zoom meeting.

But the researchers aren’t targeting laptops. Rather, they believe future iterations would find a niche application powering the billions or trillions of simple sensors and chips making up the Internet of Things. These might take measurements of local conditions in remote locations, for example, or they might be able to charge a small device.

United Kingdom Declares Octopuses, Squids Are Sentient Beings

Posted by in categories: food, government, policy

😃


The United Kingdom has confirmed what everybody who ugly cried during “My Octopus Teacher” already knew: Octopuses are sentient — capable, that is, of perceiving things like pain and pleasure.

The country is adding an amendment to its Animal Welfare Sentience Bill to recognize creatures such as octopus, crabs, squids, and lobsters along with “all other decapod crustaceans and cephalopod molluscs” as sentient creatures, according to a press release from the UK Department for Environment, Food & Rural Affairs. The bill aims to ensure animal sentience is taken into account when developing government policy, and as such could inform debates around animal rights and dietary choices.

Cheap gel film pulls buckets of drinking water per day from thin air

Posted by in categories: energy, entertainment, food, sustainability

Water scarcity is a major problem for much of the world’s population, but with the right equipment drinking water can be wrung out of thin air. Researchers at the University of Texas at Austin have now demonstrated a low-cost gel film that can pull many liters of water per day out of even very dry air.

The gel is made up of two main ingredients that are cheap and common – cellulose, which comes from the cell walls of plants, and konjac gum, a widely used food additive. Those two components work together to make a gel film that can absorb water from the air and then release it on demand, without requiring much energy.

First, the porous structure of the gum attracts water to condense out of the air around it. The cellulose meanwhile is designed to respond to a gentle heat by turning hydrophobic, releasing the captured water.

How Americans think about artificial intelligence

Posted by in categories: employment, food, health, law, robotics/AI, transportation

Artificial intelligence (AI) is spreading through society into some of the most important sectors of people’s lives – from health care and legal services to agriculture and transportation.1 As Americans watch this proliferation, they are worried in some ways and excited in others.

In broad strokes, a larger share of Americans say they are “more concerned than excited” by the increased use of AI in daily life than say the opposite. Nearly half of U.S. adults (45%) say they are equally concerned and excited. Asked to explain in their own words what concerns them most about AI, some of those who are more concerned than excited cite their worries about potential loss of jobs, privacy considerations and the prospect that AI’s ascent might surpass human skills – and others say it will lead to a loss of human connection, be misused or be relied on too much.

But others are “more excited than concerned,” and they mention such things as the societal improvements they hope will emerge, the time savings and efficiencies AI can bring to daily life and the ways in which AI systems might be helpful and safer at work. And people have mixed views on whether three specific AI applications are good or bad for society at large.

UbiQD’s Quantum Dot Tech Is an Electricity Free Lighting Option for Greenhouses

Posted by in categories: food, nanotechnology, particle physics, quantum physics

Circa 2020 Electricity free grow lights using quantum dot leds.


While costs are coming down for controlled environment agriculture, electricity remains one of the highest because it has to power the LEDs that provide the lighting formula for plant growth. But a materials science company called UbiQD wants to change that by replacing electricity with a more efficient means of lighting: quantum dots.

Quantum dots are semiconductor nanoparticles that can transport electrons. When exposed to UV lighting, these particles emit lights of various colors, and can be adjusted in size to emit a specific color. For example, larger particles emit redder wavelengths, while smaller ones shift to blue.

World-first quantum dot LED lights made from discarded rice husks

Posted by in categories: biotech/medical, computing, food, nanotechnology, quantum physics, solar power

From TVs, to solar cells, to cutting-edge cancer treatments, quantum dots are beginning to exhibit their unique potential in many fields, but manufacturing them at scale would raise some issues concerning the environment. Scientists at Japan’s Hiroshima University have demonstrated a greener path forward in this area, by using discarded rice husks to produce the world’s first silicon quantum dot LED light.

“Since typical quantum dots often involve toxic material, such as cadmium, lead, or other heavy metals, environmental concerns have been frequently deliberated when using nanomaterials,” said Ken-ichi Saitow, lead study author and a professor of chemistry at Hiroshima University. “Our proposed process and fabrication method for quantum dots minimizes these concerns.”

The type of quantum dots pursued by Saitow and his team are silicon quantum dots, which eschew heavy metals and offer some other benefits, too. Their stability and higher operating temperatures makes them one of the leading candidates for use in quantum computing, while their non-toxic nature also makes them suitable for use in medical applications.
