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 nanosheet 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 solar cells to sensors and batteries, because they have electrical, transparency, and heat-resistance functions different from those of conventional bulk materials.

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 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.

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 fuel 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 vortex rings 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 mechanical engineering at U-M and corresponding author of the study.

How do quantum particles exchange information? An intriguing hypothesis regarding quantum information has recently been validated through experimental verification conducted at TU Wien.

If you were to randomly pick an individual from a crowd who stands remarkably taller than the average, it’s quite likely that this person will also surpass the average weight. This is because, statistically, knowledge about one variable often gives us some insight into another.

Quantum physics takes these correlations to another level, establishing even more potent connections between disparate quantities: distinct particles or segments of a vast quantum system can “share” a specific amount of information. This intriguing theoretical premise suggests that the calculation of this “mutual information” is surprisingly not influenced by the system’s overall volume, but only by its surface.

It’s like Photoshop’s Warp tool, but far more powerful. You’re not just smushing pixels around, but using AI to re-generate the underlying object. You can even rotate images as if they were 3D.

The key advancement is the easy-to-use interface.

Blue Moon will be the second lunar landing system for the Artemis Program.

The first time Blue Origin bid for the landing system for Artemis, they lost to SpaceX. With Artemis V the company gets to show its stuff.

At its I/O developer conference, the search giant needs to rethink its AI strategy if it wants to catch Microsoft. The missing element? Experimentation. Google has had a rough six months. Since ChatGPT launched last November — followed by the new Bing in February and GPT-4 in March — the company has failed to establish its AI credentials. Its own offering, the “experimental” chatbot Bard, compares poorly to rivals, and insider reports have portrayed a company in panic and di… See more.

AI outputs are increasingly defining the cultural moment — just not Google’s.
