Breakthrough in gene editing: Enhanced virus-like particles promise new era in genetic disease treatment

Posted by in categories: bioengineering, biotech/medical, genetics, nanotechnology

Background: The Promise of Prime Editing

Prime editing is a promising technology for changing genomic deoxyribonucleic acid (DNA) that has the potential to be used to cure genetic diseases in individuals. Prime editors are proteins that can replace a specific deoxyribonucleic acid sequence with another. PE systems necessitate three distinct nucleic acid hybridizations and are not dependent on double-strand deoxyribonucleic acid breaks or donor deoxyribonucleic acid templates.

Researchers must devise efficient and safe techniques to deliver prime editors in tissues in the in vivo settings to fulfill PE’s objective. While viral delivery techniques such as adenoviruses and adeno-associated viruses (AAVs) can transport PE in vivo, non-viral delivery techniques like lipid nanoparticles can sidestep these concerns by packaging PEs as temporarily expressing messenger ribonucleic acids.

Towards provably efficient quantum algorithms for large-scale machine-learning models

Posted by in categories: information science, quantum physics, robotics/AI

It is still unclear whether and how quantum computing might prove useful in solving known large-scale classical machine learning problems. Here, the authors show that variants of known quantum algorithms for solving differential equations can provide an advantage in solving some instances of stochastic gradient descent dynamics.

NASA Selects a Wild Plan to “Swarm” Proxima Centauri With Thousands of Tiny Probes

Posted by in categories: energy, space

Humans have dreamed about traveling to other star systems and setting foot on alien worlds for generations. To put it mildly, interstellar exploration is a very daunting task.

As Universe Today explored in a previous post, it would take between 19,000 and 81,000 years for a spacecraft to reach Proxima Centauri using conventional propulsion (or those that are feasible using current technology). On top of that, there are numerous risks when traveling through the interstellar medium (ISM), not all of which are well-understood.

Under the circumstances, gram-scale spacecraft that rely on directed-energy propulsion (AKA lasers) appear to be the only viable option for reaching neighboring stars in this century.

Steam :: Steamworks Development :: AI Content on Steam

Posted by in categories: entertainment, policy, robotics/AI

Valve has changed its policy and will now allow games made by AI, or that use AI generated content, to be sold on Steam.


Back in June, we shared that while our goal continues to be shipping as many games as possible on Steam, we needed some time to learn about the fast-moving and legally murky space of AI technology, especially given Steam’s worldwide reach. Today, after spending the last few months learning more about this space and talking with game developers, we are making changes to how we handle games that use AI technology. This will enable us to release the vast majority of games that use it.

‘Batteries are dead’: Indoor solar panel breakthrough offers endless power source, company claims

Posted by in categories: solar power, sustainability

A US startup has demonstrated an indoor solar panel that it claims could replace billions of batteries in domestic devices like TV remotes and wireless keyboards.

California-based Ambient Photonics said its new solar cell can provide constant power from just indoor and ambient outdoor light, delivering three times more power than existing technologies.

Solar power has been used for decades in low-power electronics like calculators, though such cells have so far not been suitable for more energy-intensive devices.

Singularity Ready: Stoicism as a singularity life philosophy

Posted by in categories: education, singularity

We explore various philosophies and its principles to assess their appropriateness as guides in these accelerating exponential times

Stoicism.
Stoicism is a philosophical school that originated in ancient Greece and was founded by Zeno of Citium in the early 3rd century BC. Stoicism emphasizes rationality, virtue, and self-control as the key to leading a good life.

The philosophy teaches that individuals should focus on what they can control, accept what they cannot control, and remain indifferent to external circumstances beyond their control.

NASA has funded the development of new laser communications technology through small business Fibertek Inc. to help enable communications on Artemis II

Posted by in categories: business, space

NASA is working with private industry partners and small businesses under Artemis to produce scalable, affordable, and advanced laser communications systems that could enable greater exploration and discovery beyond Earth for the benefit of all.

Laser, or optical, communications provide missions with increased data rates – meaning that missions using laser technology can send and receive more information in a single transmission compared with those using traditional radio waves. When a spacecraft uses laser communications to send information, infrared light packs the data into tighter waves so ground stations on Earth can receive more data at once. Laser communications systems can provide 10 to 100 times higher data rates than the radio systems used by space missions today.

As science instruments evolve to capture high-definition data, missions will need expedited ways to transmit information to Earth. It would take roughly nine weeks to transmit a complete map of Mars back to Earth with current radio frequency systems. With lasers, it would only take about nine days.
