In the study, authors reveal new geometric principles of bifurcations during spatiotemporal decision-making and demonstrate that a non-Euclidean neural representation of space simplifies decision-making in multi-target environments.
A new laser-based approach has been introduced to produce artificial cartilage using 3D printing technology.
In this approach, researchers from TU Wien printed living cells within tiny football-like spheroids.
The team hopes this technique could be used to cultivate lab-grown tissue capable of replacing damaged cartilage in humans. It is a strong connective tissue found in various parts of the body that protects our joints and bones.
New research from UBC Okanagan could make monitoring gut health easier and less painful by tapping into a commonâyet often overlookedâsource of information: the mucus in our digestive system that eventually becomes part of fecal matter.
Researcher Dr. Kirk Bergstrom and post-graduate student Noah Fancy of UBCOâs Biology department have discovered a non-invasive technique to study MUC2, a critical gut protein, from what we leave behind in the bathroom.
Theie findings are published in the Journal of Biological Chemistry.
Future quantum electronics will differ substantially from conventional electronics. Whereas memory in the latter is stored as binary digits, the former is stored as qubits, which can take many forms, such as entrapped electrons in nanostructures known as quantum dots. However, challenges in transmitting this information to anything further than the adjacent quantum dot have limited qubit design.
Now, in a study recently published in Physical Review Letters, researchers from the Institute of Industrial Science at the University of Tokyo are solving this problem, They developed a new technology for transmitting quantum information over perhaps tens to a hundred micrometers. This advance could improve the functionality of upcoming quantum electronics.
How can researchers transmit quantum information, from one quantum dot to another, on the same quantum computer chip? One way might be to convert electron (matter) information into light (electromagnetic wave) informationâby generating lightâmatter hybrid states.
A meta-analysis of 39 studies showed that circulating tumor DNA presence is a prognosis factor for solid tumors after curative therapy. ctDNA has high specificity but low sensitivity. It had better accuracy in surveillance compared to landmark analyses.
Appleâs MGIE is a revolutionary AI model that can edit images based on natural language instructions, using multimodal large language models to generate expressive and imaginative edits.
The promise and peril of the internet has always been a memory greater than our own, a permanent recall of information and events that our brains canât store. More recently, tech companies have promised that virtual assistants and chatbots could handle some of the mnemonic load by both remembering and reminding. Itâs a vision of the internet as a conversation layer rather than a repository.
Thatâs what OpenAIâs latest release is supposed to provide. The company is starting to roll out long-term memory in ChatGPT âa function that maintains a memory of who you are, how you work, and what you like to chat about. Called simply Memory, itâs an AI personalization feature that turbocharges the âcustom instructionsâ tool OpenAI released last July. Using ChatGPT custom instructions, a person could tell the chatbot that theyâre a technology journalist based in the Bay Area who enjoys surfing, and the chatbot would consider that information in future responses within that conversation, like a first date who never forgets the details.
Now, ChatGPTâs memory persists across multiple chats. The service will also remember personal details about a ChatGPT user even if they donât make a custom instruction or tell the chatbot directly to remember something; it just picks up and stores details as conversations roll on. This will work across both the free (ChatGPT 3.5) and paid (ChatGPT 4) version.
Results from phase two clinical trials at UT Southwestern Medical Center showed that a suspension of gold nanocrystals taken daily by patients with multiple sclerosis (MS) and Parkinsonâs disease (PD) significantly reversed deficits of metabolites linked to energy activity in the brain and resulted in functional improvements.
The findings, published in the Journal of Nanobiotechnology (âEvidence of brain target engagement in Parkinsonâs disease and multiple sclerosis by the investigational nanomedicine, CNM-Au8, in the REPAIR phase 2 clinical trialsâ), could eventually help bring this treatment to patients with these and other neurodegenerative diseases, according to the authors.
Gold nanocrystals suspended in a water buffer represent a novel therapeutic agent developed by Clene Nanomedicine for neurodegenerative conditions. This nanomedicine, called CNM-Au8, is being investigated to treat patients with multiple sclerosis and Parkinsonâs disease in clinical trials at UT Southwestern.
