Synthetic fertilizers, one the most important developments in modern agriculture, have enabled many countries to secure a stable food supply. Among them, organic ureas (or organoureas) have become prominent sources of nitrogen for crops. Since these compounds do not dissolve immediately in water, but instead are slowly decomposed by soil microorganisms, they provide a stable and controlled supply of nitrogen, which is crucial for plant growth and function.

However, traditional methods to synthesize organoureas are environmentally harmful due to their use of toxic substances, such as phosgene. Although alternative synthesis strategies have been demonstrated, these either rely on expensive and scarce noble metals or employ catalysts that cannot be reused easily.

In a recent effort to address these challenges, a research team including Honorary Professor Hideo Hosono from Tokyo Institute of Technology, Japan, has leveraged the quantum properties of bismuth selenide (Bi2Se3) to synthesize organoureas. Their study is published in Science Advances.

Amazon is looking to position itself as the one-stop shop for AI. The e-commerce giant designs its own chips for training huge AI models. Through Amazon Bedrock customers can also design their own generative AI applications using existing models, which are all run on the Amazon cloud. The company sells its own AI applications too.

Anthropic already counts some high-profile backers, including Google and Salesforce Ventures. This support comes as tech giants continue to make massive bets on AI companies, a move sparked by Microsoft’s multi-billion dollar investment in ChatGPT maker OpenAI in January.

OpenAI’s ChatGPT can now “see, hear and speak,” or, at least, understand spoken words, respond with a synthetic voice and process images, the company announced Monday.

The update to the chatbot — OpenAI’s biggest since the introduction of GPT-4 — allows users to opt into voice conversations on ChatGPT’s mobile app and choose from five different synthetic voices for the bot to respond with. Users will also be able to share images with ChatGPT and highlight areas of focus or analysis (think: “What kinds of clouds are these?”).

The changes will be rolling out to paying users in the next two weeks, OpenAI said. While voice functionality will be limited to the iOS and Android apps, the image processing capabilities will be available on all platforms.

When the spinal cords of mice and humans are partially damaged, the initial paralysis is followed by the extensive, spontaneous recovery of motor function. However, after a complete spinal cord injury, this natural repair of the spinal cord doesn’t occur and there is no recovery. Meaningful recovery after severe injuries requires strategies that promote the regeneration of nerve fibers, but the requisite conditions for these strategies to successfully restore motor function have remained elusive.

“Five years ago, we demonstrated that can be regenerated across anatomically complete spinal cord injuries,” says Mark Anderson, a senior author of the study. “But we also realized this wasn’t enough to restore motor function, as the new fibers failed to connect to the right places on the other side of the lesion.” Anderson is the director of Central Nervous System Regeneration at. NeuroRestore and a scientist at the Wyss Center for Bio and Neuroengineering.

Working in tandem with peers at UCLA and Harvard Medical School, the scientists used state-of-the-art equipment at EPFL’s Campus Biotech facilities in Geneva to run in-depth analyses and identity which type of neuron is involved in natural spinal-cord repair after partial spinal cord injury.

A. There are so many mundane but essential administrative and clerical tasks that clog up a clinician’s workday. A computer screen is actively competing for our attention. It’s the part of the industry we – as physicians – were never trained for. But, years of “we’ve always done it that way” created this anchor on us all, leading to burnout and driving thousands out of the industry during the pandemic.

Processes vastly simplified and improved by generative AI can be a powerful recruitment tool to bring a new generation into the healthcare industry and patient care without arcane and difficult processes in their way. By eliminating needless note-taking and long nights of billing and coding for reimbursement purposes, doctors can get back to solving the real issues of patient care.

The recent introduction of the breathtaking AI tool ChatGPT has sparked a national dialogue about the future of artificial intelligence in health care, education, research, and beyond. In this session, four UCSF experts discuss AI’s current and potential uses, in areas ranging from research to education to clinical care. After a brief presentation by each speaker, DOM Chair Bob Wachter moderates a far-ranging panel discussion on the health care applications of ChatGPT.

Speakers:
Atul Butte, MD, PhD, professor of Pediatrics, Bioengineering and Therapeutic Sciences, and Epidemiology and Biostatistics; director, UCSF Bakar Computational Health Sciences Institute; chief data scientist, University of California Health System.

Daniel Lowenstein, MD, professor of Neurology; former executive vice chancellor and provost, UCSF

Sara Murray, MD, MAS, associate professor, Division of Hospital Medicine at UCSF Health; associate chief medical information officer, Inpatient Care and Data Science, UCSF Health.

The blood cancer treatment venetoclax (Venclexta; Roche, Genentech, AbbVie) was found to kill latent HIV-infected cells, indicating a possible new treatment for the virus, according to the results of a preclinical study by the Walter and Eliza Hall Institute and The Peter Doherty Institute for Infection and Immunity.

When HIV-infected cells are latent, the virus remains in the body and is untreatable by therapies currently on the market, which is why patients with HIV must stay on treatment to suppress the virus. Currently, antiretroviral therapies (ART) are the standard of care treatment for patients with HIV, however, they cannot target latent infection.

Although antiretroviral therapies are the standard of care treatment for those with HIV, the drugs cannot target latent infections; however, venetoclax, a blood cancer treatment, shows promise.

The psychedelic drug MDMA can reduce symptoms of post-traumatic stress disorder, researchers reported in a new study published Thursday.

The company sponsoring the research said it plans later this year to seek U.S. approval to market the drug, also known as ecstasy, as a PTSD treatment when combined with talk therapy.

“It’s the first innovation in PTSD treatment in more than two decades. And it’s significant because I think it will also open up other innovation,” said Amy Emerson, CEO of MAPS Public Benefit Corporation, the research sponsor.”

A study has found that the psychedelic drug MDMA, combined with talk therapy, can reduce symptoms of post-traumatic stress disorder.

You can now speak aloud to ChatGPT and hear the artificial intelligence-powered chatbot talk back.

OpenAI, the startup behind the wildly-popular chatbot, announced Monday that it is rolling out new features including the ability to let users engage in a back-and-forth voice conversation with ChatGPT.

In a company blog post Monday, OpenAI teased how this new feature can be used to request a bedtime story for your family, or settle a dinner table debate.
