A four-person crew of astronauts and a cosmonaut arrived at the International Space Station on Thursday, completing a 29-hour trek in a SpaceX capsule that began in Florida.

As if Elon Musk’s week couldn’t be more eventful, the Tesla (TSLA) CEO gave the automotive world more news to chew on.

In a tweet last night, Musk said Tesla has begun production of its long-awaited electric Tesla Semi truck, and that deliveries to Pepsi (PEP) would begin on December 1st. In a follow-up tweet, Musk said the semi would have 500 miles of range and would be “super fun to drive.”

Intel Corp.’s two primary research organizations, Intel Labs and Components Research, announced today that they’re making big progress as they work toward large-scale production of quantum computing processors.

At the 2022 Silicon Quantum Electronics Workshop in Orford, Quebec, Intel’s researchers said that they’ve been able to demonstrate the highest reported yield and uniformity rate when manufacturing “silicon spin qubit devices” at the company’s transistor research and development facility. The research is believed to be a key milestone for Intel as it moves toward being able to fabricate quantum computing chips on its existing transistor manufacturing processes.

Intel is a key player in the race to build quantum computers, which are more advanced machines that encode data as “qubits,” as opposed to the conventional bits used in traditional computers. The advantage of qubits is they’re not restricted to states of 1 or 0. They can also exist as both states at the same time, a characteristic that’s known as superposition.

NIH researchers reveal new insights on how genetic architecture determines gene expression, tissue-specific function, and disease phenotype in blinding diseases.

National Eye Institute (NEI) scientists have mapped the organization of human retinal cell chromatin. These are the fibers that package 3 billion nucleotide-long DNA

Editing technology is precise and broadly applicable to all tissues and species.

Scientists at Duke University have developed an RNA

Ribonucleic acid (RNA) is a polymeric molecule similar to DNA that is essential in various biological roles in coding, decoding, regulation and expression of genes. Both are nucleic acids, but unlike DNA, RNA is single-stranded. An RNA strand has a backbone made of alternating sugar (ribose) and phosphate groups. Attached to each sugar is one of four bases—adenine (A), uracil (U), cytosine ©, or guanine (G). Different types of RNA exist in the cell: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA).

No one imaging mode can catch everything that’s going on inside the brain, since it is such a complex organ. Multiple “brain maps” have emerged over the years, with each focusing on different brain processes, from metabolism to cognitive function. These maps are indeed important, but using them in isolation limits the discoveries scientists can make from them.

More than forty existing brain maps have now been collected in one place by a team from The Neuro. Called neuromaps, the database will help researchers find correlations between patterns across different brain regions, modalities, spatial scales, and brain functions. To assist researchers in differentiating between a relevant association and a random pattern, it offers a standardized space to see each map in comparison to one another and evaluates the statistical significance of these comparisons. Additionally, the neuromaps database helps standardize the code across maps, to improve reproducibility of results.

BYU engineers design a molten-salt reactor that will never melt down and fits on a flatbed truck.

Developed at Brigham Young University, the micro-reactor can fit on a flatbed truck and produce enough energy to power 1,000 homes.

Sending rockets into space requires sacrificing expensive equipment, burning massive amounts of fuel, and risking potential catastrophe. So in the space race of the 21st century, some engineers are abandoning rockets for something more exciting: elevators. What would it take to build such a structure? Fabio Pacucci explores the physics behind modern space elevators. [Directed by Tjoff Koong Studios, narrated by Addison Anderson].

An exploration of what I think is one of the spookiest solutions to the Fermi Paradox that could explain SETI’s great silence.
