Navigating advanced technology transitions: using lessons from nanotechnology

Posted by in categories: biotech/medical, nanotechnology, quantum physics, robotics/AI

As researchers, developers, policymakers and others grapple with navigating socially beneficial advanced technology transitions — especially those associated with artificial intelligence, DNA-based technologies, and quantum technologies — there are valuable lessons to be drawn from nanotechnology. These lessons underscore an urgent need to foster collaboration, engagement and partnerships across disciplines and sectors, together with bringing together people, communities, and organizations with diverse expertise, as they work together to realize the long-term benefits of transformative technologies.

Awesome photo of Earth and the Moon captured by Orion from deep space

Posted by in categories: engineering, space travel

In an extraordinary feat of engineering and international collaboration, the Orion spacecraft, a part of NASA’s Artemis I mission, has achieved a remarkable milestone in space exploration. The spacecraft ventured some 267,000 miles from Earth and roughly 40,000 miles from the Moon, surpassing the distance record set by the Apollo 13 mission over half a century ago.

In this photo, the Orion capsule, along with the Earth and the Moon, appeared to be posing for a ‘family portrait.’ This iconic image marks a pivotal moment in the mission’s journey, symbolizing the culmination of years of meticulous planning and execution.

Orion’s journey from Earth began a year ago, on November 16, 2022, when NASA’s mega Moon rocket, the Space Launch System, lifted off from the Kennedy Space Center in Florida, USA. The uncrewed Orion spacecraft was placed into Earth orbit, marking the beginning of a new era in lunar exploration.

Potential Glaucoma Treatment Strategy to Guide Stem Cells to the Retina

Posted by in category: biotech/medical

Scientists have developed a novel approach that allows stem cells to be turned into retinal ganglion cells that are capable of migrating and surviving in the eye’s retina. This approach presents a promising new treatment strategy for diseases like glaucoma, in which the loss of retinal ganglion cells caused by the disease leads to irreversible vision loss.

Glaucoma is one of the leading causes of blindness worldwide, and vision loss, due to the loss of retinal ganglion cells (RGCs), cannot currently be reversed with any treatment. Some studies have looked at replacing RGCs through cell transplants, but this process is still in the research and development stage and fraught with limitations that highlight a need for a more precise manner of effectively repopulating these cells in the retina. Now, a multidisciplinary team led by researchers at the Schepens Eye Research Institute of Mass Eye and Ear has identified a promising new strategy for glaucoma cell replacement therapy.

In their new study, researchers changed the microenvironment in the eye in a way that enabled them to take stem cells from blood and turn them into retinal ganglion cells that were capable of migrating and surviving into the eye’s retina. They conducted their study on the adult mouse retina, but the work’s implications could one day be applied to human retina, according to the researchers who published their findings November 6th in Proceedings of the National Academy of Sciences.

Improving healthspan and longevity can be just like riding a bike

Posted by in categories: biotech/medical, life extension, robotics/AI

High-intensity interval training (HIIT) has become very popular; alternating short periods of intense anaerobic exercise with recovery periods, it is designed to help to decrease body fat, increase strength and endurance, and improve healthspan in protocols that last approximately half an hour.

But these days, even finding half an hour can be tricky – enter CAROL Bike, an exercise bike designed around Reduced Exertion HIIT (REHIT) and AI-personalization, meaning an effective workout can be delivered in just 5 minutes.

Physicists find ultimate limit for how accurate clocks can be

Posted by in categories: computing, quantum physics

A fundamental trade-off between the resolution of a clock and its accuracy could have important implications for quantum computers, which must measure short timescales accurately.

From The Big Bang To The Present: The Evolution Of The Universe

Posted by in categories: cosmology, evolution, physics

Author: Sharika Dhakappa The Big Bang is the most widely accepted theory of how the universe originated. Most physicists believe that the tremendously large universe we observe today began as a tiny, dense point. If the evolution of the universe till today were to be depicted as a movie, the Big Bang would be the beginning of it. We do not yet know what came before the Big Bang or whether that is even a meaningful question to ask. The cosmic movie would run for 13.8 billion years which is the current age of the universe as estimated by the WMAP satellite.

Peculiar transient behaviors of organic electrochemical transistors governed by ion injection directionality

Posted by in categories: chemistry, computing

Few studies have investigated the structural properties of organic mixed ionic-electronic conductors in relation to the transient device characteristics. Here, Kim et al. show that backbone-dependent molecular orientation affects ion injection directionality, which determines ion mobility and transient response.

Analyst Panel Says Take the Quantum Computing Plunge Now…

Posted by in categories: quantum physics, robotics/AI

Should you start exploring quantum computing? Yes, said a panel of analysts convened at Tabor Communications HPC and AI on Wall Street conference earlier this year.

Without doubt, the quantum computing landscape remains murky. Yet in the past ~5 years virtually every aspect of quantum computing has raced forward. At least one 1000-plus-qubit system is edging towards user access now and another is expected by year-end. There’s been a proliferation of software offerings up and down the “quantum stack” though it’s hardly complete. Most promising, what were a few POC use-case explorations has mushroomed into very many efforts across many sectors.

What are we waiting for? Against the backdrop of astonishing progress are also very hard technical problems. Error correction/mitigation tops the list. Effective quantum networking is another. Polished applications. Too many qubit types to choose from (at least for now.) Scale matters – it’s expected that millions of qubits may be needed for practical quantum computing These aren’t trivial challenges. Why bother?
