Have scientists found a “brake pedal” for aging?

A new protein discovery may have highlighted a ‘switch’ in brain cells that slows down inflammation and aging.

The other day a friend proudly told me she wrote a heartwarming graduation card to her teenage son. “Okay,” she confessed. “I
How long was your card? I asked her.
Not only that, but many also couldn’t even generate a topic on their own. They lacked creativity to dream up their own ideas, much less the critical thinking skills to put themselves in the shoes of their audience, imagining what would land. But they all had 4.0 GPAs or higher and came from private schools in Orange County and LA, reflecting our watered-down educational system.
According to the Financial Times, Meta is in talks with Magic Leap, an AR headset company, to look into licensing the latter’s tech.
Meta is reportedly in talks with a company called Magic Leap with an eye to a partnership that could see Meta developing its alternative reality (AR) headset in the future.

With LIMA, Meta’s AI researchers introduce a new language model that achieves GPT-4 and Bard level performance in test scenarios, albeit fine-tuned with relatively few examples.
LIMA stands for “Less is More for Alignment,” and the name hints at the model’s function: It is intended to show that with an extensively pre-trained AI model, a few examples are sufficient to achieve high-quality results.
Few examples in this case means that Meta manually selected 1,000 diverse prompts and their output from sources such as other research papers, WikiHow, StackExchange, and Reddit.
To make sense of mysteries like quantum mechanics and the passage of time, theorists are trying to reformulate physics to include subjective experience as a physical constituent of the world.
Summary: Scientists present a hypothesis dubbed “Cytoelectric Coupling” suggesting electrical fields within the brain can manipulate neuronal sub-cellular components, optimizing network stability and efficiency. They propose these fields allow neurons to tune the information-processing network down to the molecular level.
Comparatively, this process is akin to households arranging their TV setup for optimal viewing experience. The theory, open for testing, could significantly enhance our understanding of the brain’s inner workings.
Summary: Neurons in the hippocampus vary in function depending on their exact genetic identity. The study revealed these neurons, once believed to be homogeneous, are quite diverse and encode task-related information differently based on their location. This newfound understanding of neuronal diversity could lead to better comprehension of brain functions, memory capacity, and potentially advance disease treatment strategies.
Key Facts:
Summary: Researchers used artificial intelligence to predict how enzymes interact with various substrates. The team developed an AI model that can accurately predict whether an enzyme can work with a particular molecule.
Their enzyme substrate prediction (ESP) model provides a valuable tool for drug research and biotechnology, with applications ranging from the creation of new drugs to the production of biofuels.
I asked Bard chatbot whether we should fear Google. It shared concerns about Google you’d never expect would come from an AI created by Google.
Scientists have figured out a way to retrieve tiny traces of human genetic material called environmental DNA (eDNA) from thin air.
