Diamond has long been the preferred material for quantum sensing, but its size limits its applications. Recent research highlights hBN’s potential as a replacement, especially after TMOS researchers developed methods to stabilize its atomic defects and study its charge states, opening doors for its integration into devices where diamond can’t fit.

Diamond has long held the crown in the realm of quantum sensing, thanks to its coherent nitrogen-vacancy centers, adjustable spin, magnetic field sensitivity, and capability to operate at room temperature. With such a suitable material so easy to fabricate and scale, there’s been little interest in exploring diamond alternatives.

However, this titan of the quantum domain has a vulnerability. It’s simply too large. Much like how an NFL linebacker isn’t the top pick for a jockey in the Kentucky Derby, diamond falls short when delving into quantum sensors and data processing. When diamonds get too small, the super-stable defect it’s renowned for begins to crumble. There is a limit at which a diamond becomes useless.

The SpaceX Crew-7 flight will take an international team of four to the space station. Moghbeli will be the only American abroad, and is leading the mission.

The daughter of Iranian political refugees, Moghbeli went to astronaut camp as a teenager and got a degree at MIT. She played three sports, including basketball, and with space in mind studied aeronautical engineering.

She later had a gutsy career as a Marine attack helicopter pilot, serving in more than 150 combat missions – part family tradition, part service to her country and part in service to her space dreams.

An injection of a specific blood factor can replicate exercise’s brain benefits, offering potential treatments for age-related cognitive decline.

Pre-clinical trials by University of Queensland scientists have found that an injection of a specific blood factor can replicate the benefits of exercise in the brain.

Dr. Odette Leiter and Dr. Tara Walker from UQ’s Queensland Brain Institute led a team that discovered platelets, the tiny blood cells critical for blood clotting, secrete a protein that rejuvenates neurons in aged mice in a similar way to physical exercise.

On Tuesday, OpenAI announced fine-tuning for GPT-3.5 Turbo—the AI model that powers the free version of ChatGPT—through its API. It allows training the model with custom data, such as company documents or project documentation. OpenAI claims that a fine-tuned model can perform as well as GPT-4 with lower cost in certain scenarios.

So basically, fine-tuning teaches GPT-3.5 Turbo about custom content, such as project documentation or any other written reference. That can come in handy if you want to build an AI assistant based on GPT-3.5 that is intimately familiar with your product or service but lacks knowledge of it in its training data (which, as a reminder, was scraped off the web before September 2021).

A study published in Scientific Reports has shed light on the intricate relationship between the sense of presence in virtual reality (VR) environments and cognitive abilities. The study, titled “The role of sense of presence in expressing cognitive abilities in a virtual reality task: an initial validation study,” was conducted by a team of researchers coordinated by Dr. Andrea Chirico and marks a significant advancement in our understanding of how immersive technologies can influence cognitive functions.

The research team, which includes Prof. Antonio Giordano, Prof. Fabio Lucidi (Sapienza University of Rome), Dr. Luigi De Pietro (CNR ICAR, Italy), and others, set out to investigate the extent to which the sense of presence—the feeling of being “inside” a —impacts an individual’s cognitive performance. By employing advanced VR technology and designing a range of tasks to test cognitive abilities, the researchers were able to gather valuable insights.

One of the key findings of the study is that a stronger sense of presence is positively correlated with enhanced cognitive abilities. Participants who reported a heightened feeling of presence in the virtual tasks demonstrated improved performance in various cognitive domains. These domains include memory, attention, problem-solving, and decision-making.
