Self-assembling molecules suffocate cancer cells within hours

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

The technology at the heart of this research takes aim at one of the key metabolic functions of cells in all living things called ATP, or adenosine triphosphate. This molecule is the primary energy carrier in cells, capturing chemical energy from the breakdown of food molecules and distributing it to power other cellular processes.

Among those cellular processes is the proliferation of cancerous cells, and because of this we have seen ATP implicated in previous anti-cancer breakthroughs. The authors of the new study sought to cut off the supply of ATP, which is generated as mitochondria soak up oxygen and convert it into the molecule.

Scientists Discover Plastic-Eating Worms That Digest Styrofoam

Posted by in categories: biological, food, sustainability

Humanity has left its mark on the Earth, from cities of steel to mountains of styrofoam. The latter is proving to be a problem, as many of the synthetic materials we produce don’t degrade in anything approaching a human timescale. Scientists have long sought to develop better plastic recycling methods, and the answer might be crawling around in the wild. Researchers from the University of Queensland in Australia say that a beetle larvae (it looks like a worm in larval form) may hold the key to eliminating polystyrene from the environment.

Styrofoam, technically known as polystyrene, is one of the most common types of plastic, accounting for 7–10 percent of all the non-fibrous plastics produced. You probably encounter it frequently in packing materials where the material’s foam conformation is adept at absorbing impacts. The solid version of polystyrene can be used to make transparent containers, disposable utensils, and more. However, polystyrene carries a recycling ID of 6, meaning it’s difficult to process and is not accepted at most curbside pickups.

Scientists have long searched for microbes or insect enzymes that could help break down durable plastics like polystyrene, and a beetle known as Zophobas morio might have it. It’s a species of darkling beetle, and the larval form is more commonly known as a superworm. They look like larger mealworms and are often used as a food source for insectivorous animals. In addition to being a high-protein, low-carb snack, this creature’s gut carries a unique mixture of bacterial enzymes that can digest polystyrene. The researchers reported that darkling beetle larva can subsist entirely on a diet of polystyrene — they can even grow while eating a pile of plastic.

Scientists Have Made a Human Microbiome From Scratch

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

Our bodies are home to hundreds or thousands of species of microbes — nobody is sure quite how many. That’s just one of many mysteries about the so-called human microbiome.

Our inner ecosystem fends off pathogens, helps digest food and may even influence behavior. But scientists have yet to figure out exactly which microbes do what or how. Many studies suggest that many species have to work together to do each of the microbiome’s jobs.

To better understand how microbes affect our health, scientists have for the first time created a synthetic human microbiome, combining 119 species of bacteria naturally found in the human body. When the researchers gave the concoction to mice that did not have a microbiome of their own, the bacterial strains established themselves and remained stable — even when the scientists introduced other microbes.

Uber Taps Nuro’s Street-Legal Robots For Food Deliveries

Posted by in categories: food, law, robotics/AI, sustainability

Nuro, a Softbank-backed developer of street-legal autonomous, electric delivery vehicles, has struck a long-term partnership with Uber to use its toaster-shaped micro-vans to haul food orders, groceries and other goods to customers in Silicon Valley and Houston using the Uber Eats service starting this year.

People using the Uber Eats app in Houston and Mountain View, California (where Nuro is based) will be able to order deliveries using the new autonomous service this fall, with plans to expand the program to other parts of the San Francisco Bay Area in the months ahead, the companies said.

Pioneering mathematical formula paves way for exciting advances in health, energy, and food industry

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

A groundbreaking mathematical equation that could transform medical procedures, natural gas extraction, and plastic packaging production in the future has been discovered.

The new equation, developed by scientists at the University of Bristol, indicates that diffusive movement through permeable material can be modeled exactly for the very first time. It comes a century after world-leading physicists Albert Einstein and Marian von Smoluchowski derived the first diffusion equation, and marks important progress in representing motion for a wide range of entities from microscopic particles and natural organisms to man-made devices.

Until now, scientists looking at particle motion through porous materials, such as biological tissues, polymers, various rocks and sponges have had to rely on approximations or incomplete perspectives.

Scientists Wire Chip to Cockroaches’ Nervous System, Allow Them to Be Remote Controlled

Posted by in categories: computing, cyborgs, food

According to the researcher, the same technology could be applied to beetles and cicadas as well.

It’s a fun and futuristic vision: an army of remotely controlled cyborg insects that can infiltrate hard to reach locations or monitor crops.

But scientists will have to advance the tech carefully — nobody wants to risk a cyborg cockroach uprising.
