Plastic waste is a problem. Most plastics can’t be recycled, and many use finite, polluting petrochemicals as the basic ingredients. But that’s changing. In a study published today in Nature Sustainability, researchers successfully engineered microbes to make biological alternatives for the starting ingredients in an infinitely recyclable plastic known as poly(diketoenamine), or PDK.

The finding comes from collaboration among experts at three facilities at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab): the Molecular Foundry, the Joint BioEnergy Institute (JBEI), and the Advanced Light Source.

“This is the first time that bioproducts have been integrated to make a PDK that is predominantly bio-based,” said Brett Helms, staff scientist at the Molecular Foundry who led the project. “And it’s the first time that you see a bio-advantage over using petrochemicals, both with respect to the material’s properties and the cost of producing it at scale.”

Is there such a thing as a longevity mantra? A routine or set of guidelines that can help you extend your lifespan and healthspan – in a nutshell, giving you more life in your years and more years in your life?

A new study involving over 700,000 US veterans reports that people who adopt eight healthy lifestyle habits by middle age can expect to live substantially longer than those with few or none of these habits.

While it’s a list full of the usual suspects, having such a large data set has allowed the research team to put some numbers alongside these pillars of longevity.

British health tech startup Twinn Health recently emerged from stealth, boasting an AI-powered platform that analyzes MRI scans to detect preventable disease “earlier than ever before.” Starting with metabolic disease, the company’s AI platform leverages validated imaging biomarkers to improve diagnosis and treatment decisions.

With age-related frailty and liver disease also on its roadmap, Twinn Health is positioning itself squarely in the domain of longevity and preventive healthcare. The company is supported by WAED, a $500 million venture capital fund backed by Saudi Aramco, which invests in innovative tech-based startups.

Longevity. Technology: Magnetic resonance imaging (MRI) has been used in healthcare for decades and is widely used in hospitals and clinics for the diagnosis and follow-up of disease. In recent years, AI tools have appeared that help identify the presence of specific conditions within MRI scans, but the technology is not yet widely used in healthcare to support healthspan and longevity improvements. Twinn Health aims to change that, combining MRI and AI to enable the early detection and management of multiple age-related diseases.

Arm and its industry partners have announced a new global initiative dubbed the Semiconductor Education Alliance.

The effort includes partners across industry, academia and research in an effort to combat the world’s shortage of semiconductor engineers and other tech talent, Gary Campbell, executive vice president of central engineering at Arm, said in an interview with VentureBeat.

An upcoming resupply mission to the International Space Station will include stem cells destined to be grown into tiny, 3D models of the human brain.

How do we communicate with spacecraft? For decades, satellites have beamed data back to Earth by way of radio waves, with a network of ground-based antennas collecting the incoming information. Now, we’re exploring laser communications, technology that will allow us to receive more data from farther than ever before — faster, too. NASA space communications expert Risha George tells us more.

NASA is also developing ways to communicate with invisible infrared lasers.

Laser communications offer missions higher data rates than ever before, allowing us to transmit more data at once.

A new solar-powered high-altitude drone has successfully navigated a stratospheric test, opening the door to a new set of possibilities for unmanned vehicles, not least in modern warfare.

The PHASA-35 solar and battery-powered unmanned aerial system reached an altitude of 66,000 feet during a 24-hour test flight launched from New Mexico in June, British defense giant BAE Systems said in mid-July.

The stratospheric test, which comes after the system’s maiden flight back in 2020, “marks a significant milestone” in the development program started in 2018, BAE said in a press release.

WASHINGTON, July 27 (Reuters) — The Department of Energy said on Thursday it is accepting applications from states and territories for $8.5 billion in rebate programs for upgrades in U.S. homes that aim to lower energy bills and increase energy efficiency.

The rebates for items including insulation, heat pumps, and efficient appliances will be available to consumers after states and territories apply for and get funds from the department. The two rebate programs were funded by President Joe Biden’s Inflation Reduction Act that fellow Democrats in Congress passed last year without a single Republican vote.

The rebate programs will save up to $1 billion a year in energy costs and support about 50,000 jobs in construction, manufacturing and other businesses, the department said.
