Exploring the Relationship Between Artificial Intelligence (AI) and the Metaverse

Posted by in categories: augmented reality, internet, robotics/AI, virtual reality

Artificial intelligence (AI) and the metaverse are some of the most captivating technologies of the 21st century so far. Both are believed to have the potential to change many aspects of our lives, disrupt different industries, and enhance the efficiency of traditional workflows. While these two technologies are often looked at separately, they’re more connected than we may think. Before we explore the relationship between AI and the metaverse, let’s start by defining both terms.

The metaverse is a concept describing a hypothetical future design of the internet. It features an immersive, 3D online world where users are represented by custom avatars and access information with the help of virtual reality (VR), augmented reality (AR), and similar technologies. Instead of accessing the internet via their screens, users access the metaverse via a combination of the physical and digital. The metaverse will enable people to socialize, play, and work alongside others in different 3D virtual spaces.

A similar arrangement was described in Neal Stephenson’s 1992 science-fiction novel Snow Crash. While it was perceived as a fantasy mere three decades ago, it seems like it could become a reality sooner rather than later. Although the metaverse isn’t fully in existence yet, some online platforms incorporate elements of it. For example, video games like Fortnite and Horizon World port multiple elements of our day-to-day lives into the online world.

Researchers Invent E-skin That ‘Talks’ to the Brain

Posted by in categories: biotech/medical, cyborgs

Summary: Researchers have developed an artificial electronic skin (e-skin) capable of converting sensory inputs into electrical signals that the brain can interpret. This skin-like material incorporates soft integrated circuits and boasts a variety of sensory abilities, including temperature and pressure detection.

This advance could facilitate the creation of prosthetic limbs with sensory feedback or advanced medical devices. The e-skin operates at a low voltage and can endure continuous stretching without losing its electrical properties.

Quantum Biology Could Revolutionize Our Understanding of How Life Works

Posted by in categories: biotech/medical, chemistry, genetics, mobile phones, nanotechnology, quantum physics, wearables

In my work, I build instruments to study and control the quantum properties of small things like electrons. In the same way that electrons have mass and charge, they also have a quantum property called spin. Spin defines how the electrons interact with a magnetic field, in the same way that charge defines how electrons interact with an electric field. The quantum experiments I have been building since graduate school, and now in my own lab, aim to apply tailored magnetic fields to change the spins of particular electrons.

Research has demonstrated that many physiological processes are influenced by weak magnetic fields. These processes include stem cell development and maturation, cell proliferation rates, genetic material repair, and countless others. These physiological responses to magnetic fields are consistent with chemical reactions that depend on the spin of particular electrons within molecules. Applying a weak magnetic field to change electron spins can thus effectively control a chemical reaction’s final products, with important physiological consequences.

Currently, a lack of understanding of how such processes work at the nanoscale level prevents researchers from determining exactly what strength and frequency of magnetic fields cause specific chemical reactions in cells. Current cell phone, wearable, and miniaturization technologies are already sufficient to produce tailored, weak magnetic fields that change physiology, both for good and for bad. The missing piece of the puzzle is, hence, a “deterministic codebook” of how to map quantum causes to physiological outcomes.

Researchers report technique to fabricate nanosheets in one minute

Posted by in categories: biotech/medical, solar power

A research group led by Professor Minoru Osada (he, him) and postdoctoral researcher Yue Shi (she, her) at the Institute for Future Materials and Systems (IMaSS), Nagoya University in Japan, has developed a new technology to fabricate nanosheets, thin films of two-dimensional materials a couple of nanometers thick, in about one minute.

This technology enables the formation of high-quality, large films with a single click without the need for specialized knowledge or technology. Their findings are expected to contribute to developing the industrial manufacturing process for various types of nanosheet devices. The study was published in ACS Applied Materials & Interfaces.

Nanosheets have a thickness that is measured in nanometers. Nanometers are so thin that the sheets cannot be seen from the side with the naked eye. They have potential uses in several different fields, including electronics, catalysis, energy storage, and biomedicine. Those made from graphene and inorganic nanosheets are being tested for use in a range of devices, from to sensors and batteries, because they have electrical, transparency, and heat-resistance functions different from those of conventional bulk materials.

SpaceX plans to launch Falcon 9 from both the East and West coasts hours apart

Posted by in categories: internet, satellites

SpaceX plans to launch two Falcon 9 rockets hours apart from Florida and California. Starlink group 6–3 will launch from Cape Canaveral Space Force Station with a planned launch time of 12:41 AM ET (04:41 UTC) and from Vandenberg Space Force Base, Iridium OneWeb rideshare launch at 6:19 AM PT (13:19 UTC).

First up, SpaceX will launch booster 1,076 on its 5th flight to deliver 22 Starlink V2 mini-satellites to a 43 degree orbit inclination. The 22 Starlink V2 mini-satellites come in at a combined ~17.6 metric tons, potentially setting the record for the most mass to low Earth orbit for a Falcon 9. This shows a gradual increase in the confidence of the Falcon 9 to deliver high-mass payloads to orbit while maintaining the ability to recover the first stage. On station for this recovery is the droneship “A Shortfall of Gravitas,” stationed roughly 636 km downrange, just East of the Bahamas.

The current weather outlook for this launch has a 60% chance of violating launch criteria at the opening of the launch window. However, this launch has three more opportunities, 1:13 AM ET (05:31 UTC), 2:19 AM ET (06:19 UTC), and 3:09 AM ET (07:09 UTC) in which the weather improves to a 40% chance of violating launch criteria.

Researchers Discover New Way To Fight the Aging Process

Posted by in categories: biotech/medical, life extension

Researchers at the University of Cologne have discovered a protein complex, called DREAM, that inhibits DNA repair mechanisms in human, mouse, and nematode cells, thereby contributing to aging and disease. They successfully suppressed the DREAM complex with a pharmaceutical agent, boosting the cells’ resilience to DNA damage, and suggesting potential new treatments for aging and cancer, although further research is needed.

Researchers at the University of Cologne have found that a protein complex impedes the repair of genomic damage in human cells, mice, and the nematode Caenorhabditis elegans. Furthermore, they were able to successfully obstruct this complex with a pharmaceutical agent for the first time.

When we suppress the so-called DREAM complex in body cells, various repair mechanisms kick in, making these cells extremely resilient towards all kinds of DNA.

Demystifying vortex rings in nuclear fusion and supernovae

Posted by in categories: engineering, nuclear energy, physics, space

Better understanding the formation of swirling, ring-shaped disturbances—known as vortex rings—could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source.

The model developed by researchers at the University of Michigan could aid in the design of the capsule, minimizing the energy lost while trying to ignite the reaction that makes stars shine. In addition, the model could help other engineers who must manage the mixing of fluids after a shock wave passes through, such as those designing supersonic jet engines, as well as physicists trying to understand supernovae.

“These move outward from the collapsing star, populating the universe with the materials that will eventually become nebulae, planets and even new stars—and inward during fusion implosions, disrupting the stability of the burning fusion fuel and reducing the efficiency of the reaction,” said Michael Wadas, a doctoral candidate in at U-M and corresponding author of the study.
