In December 2022, NASA’s MAVEN mission observed a rare solar event causing the solar wind to “disappear.” This led to significant changes in Mars’ atmosphere and magnetosphere, including their expansion. Scientists, astounded by the data, formed a working group to study this phenomenon. Credit: SciTechDaily.com.

NASA ’s MAVEN detected a unique solar event that drastically affected Mars ’ atmosphere, offering vital insights into the planet’s interaction with solar phenomena.

In December 2022, NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) mission observed the dramatic and unexpected “disappearance” of a stream of charged particles constantly emanating off the Sun, known as the solar wind. This was caused by a special type of solar event that was so powerful, it created a void in its wake as it traveled through the solar system.

Our most advanced text-to-image diffusion technology, delivering high-quality, photorealistic outputs that are closely aligned and consistent with the user’s prompt.

Imagen 2 is our most advanced text-to-image diffusion technology, delivering high-quality, photorealistic outputs that are closely aligned and consistent with the user’s prompt. It can generate more lifelike images by using the natural distribution of its training data, instead of adopting a pre-programmed style.

Imagen 2’s powerful text-to-image technology is available for developers and Cloud customers via the Imagen API in Google Cloud Vertex AI.

The Google Arts and Culture team is also deploying our Imagen 2 technology in their Cultural Icons experiment, allowing users to explore, learn and test their cultural knowledge with the help of Google AI.

Headquartered in Oxford, UK, MitoRx is working on orally delivered mitochondrial protective therapeutics targeting mitochondrial dysfunction linked to the progression of conditions such as Duchenne muscular dystrophy and Huntington’s disease, along with other neurodegenerative diseases. The company says the new funding will be allocated towards its preclinical work in Huntington’s disease, activating its first neurodegenerative disease program, and exploring research collaborations and partnerships.

MitoRx anticipates delivering preclinical results in Duchenne muscular dystrophy, Huntington’s disease, and COPD next year.

“Interim results in our Duchenne program demonstrate that our muscle-penetrative lead asset preserves strength in oxidative muscle, and confirms mitochondrial modulation,” said Dr Christine Charman, Chief Development Officer at MitoRx. “These results will be presented at the Muscular Dystrophy Association Clinical and Scientific Conference in Orlando during March 2024.”

Nowadays, many malicious elements online use AI to digitally expand their operations, and experts claim that such AI-generated fraud is only expected to worsen.

This increasing criminal use of AI challenges security agencies as they look to capture and convict criminals. Unfortunately, most agencies do not have the resources to handle the increased volume of cases, and those that do struggle immensely with differing regulations across jurisdictions. Furthermore, the lack of federal legislation on AI leaves agencies largely on their own to navigate these evolving challenges.

According to a notice the agency posted on the government contracting portal SAM.gov on Thursday (Dec. 7), the technology was developed by researchers at NASA’s Langley Research Center in Virginia and has been studied for use in a simulated entry into Neptune’s atmosphere. A separate 2021 study of the same technology studied it for use in the atmosphere of Mars.

The agency claims its MHD system is “simpler than conventional methods for control of hypersonic craft (e.g., chemical propulsion, shifting flight center of gravity, or trim tabs) and enables new entry, descent, and landing mission architectures.”

If successful, the experiments would not only affirm some of the theories proposing the quantum nature of gravity but could also finally unify general relativity with theories of quantum mechanics.

Unifying General Relativity with Quantum Mechanics Has Proven Elusive

“General relativity and quantum mechanics are the two most fundamental descriptions of nature we have,” explains the press release announcing the new experiments. “General relativity explains gravity on large scales while quantum mechanics explains the behaviour of atoms and molecules.”

Artificial intelligence tools hold promise for applications ranging from autonomous vehicles to the interpretation of medical images. However, a new study finds these AI tools are more vulnerable than previously thought to targeted attacks that effectively force AI systems to make bad decisions.

At issue are so-called “adversarial attacks,” in which someone manipulates the data being fed into an AI system in order to confuse it. For example, someone might know that putting a specific type of sticker at a specific spot on a stop sign could effectively make the stop sign invisible to an AI system. Or a hacker could install code on an X-ray machine that alters the image data in a way that causes an AI system to make inaccurate diagnoses.

“For the most part, you can make all sorts of changes to a stop sign, and an AI that has been trained to identify stop signs will still know it’s a stop sign,” says Tianfu Wu, co-author of a paper on the new work and an associate professor of electrical and computer engineering at North Carolina State University. “However, if the AI has a vulnerability, and an attacker knows the vulnerability, the attacker could take advantage of the vulnerability and cause an accident.”
