A new ingestible capsule can monitor vital signs from within the patient’s GI tract. The sensor could be used for less intrusive monitoring of sleep disorders such as sleep apnea, or for detecting opioid overdoses.

Diagnosing sleep disorders such as sleep apnea usually requires a patient to spend the night in a sleep lab, hooked up to a variety of sensors and monitors. Researchers from MIT, Celero Systems, and West Virginia University hope to make that process less intrusive, using an ingestible capsule they developed that can monitor vital signs from within the patient’s GI tract.

The capsule, which is about the size of a multivitamin, uses an accelerometer to measure the patient’s breathing rate and heart rate. In addition to diagnosing sleep apnea, the device could also be useful for detecting opioid overdoses in people at high risk, the researchers say.

What can a quantum information theorist say about the certainty of arithmetic and the universality of mathematical truth?

New research from North Carolina State University and Michigan State University opens a new avenue for modeling low-energy nuclear reactions, which are key to the formation of elements within stars. The research lays the groundwork for calculating how nucleons interact when the particles are electrically charged.

The work appears in Physical Review Letters.

Predicting the ways that atomic nuclei —clusters of protons and neutrons, together referred to as nucleons—combine to form larger compound nuclei is an important step toward understanding how elements are formed within stars.

The downturn in the technology sector — dragged by inflation, higher interest rates and geopolitical events — continues to persist, and one of the most acutely impacted areas has been VC funding for startups, particularly those outside the U.S. According to VC firm Atomico, companies in Europe are on track to raise just $42 billion this year — less than half the $85 billion that startups in the region raised in 2022.

The figures come from Atomico’s big report on the state of European tech, which it publishes annually.

It also found that startups in the region are raising less at each stage of funding from Seed through to Series C (and beyond), with later stage and larger companies feeling a particular pinch: just 7 “unicorns” (startups with a valuation of more than $1 billion) are set to emerge this year in Europe, compared to 48 in 2022 and 108 in 2021.

It comes 3 years after Amazon debuted its ‘handy’ authentication service for consumers.

Amazon’s cloud computing subsidiary AWS (Amazon Web Services) has lifted the lid on a new palm-scanning identity service that allows companies to authenticate people when entering physical premises.

The announcement comes as part of AWS’s annual Re: Invent conference, which is running in Las Vegas for the duration of this week.

Elon Musk is hyping the imminent release of his ChatGPT competitor Grok, yet another example of how his entire personality is just itself a biological LLM made by ingesting all of Reddit and 4chan. Grok already seems patterned in many ways off of the worst of Elon’s indulgences, with the sense of humor of a desperately unfunny and regressive internet troll, and biases informed by a man whose horrible, dangerous biases are fully invisible to himself.

There are all kinds of reasons to be wary of Grok, including the standard reasons to be wary of any current LLM-based AI technology, like hallucinations and inaccuracies. Layer on Elon Musk’s recent track record for disastrous social sensitivity and generally harmful approach to world-shaping issues, and we’re already looking at even more reason for concern. But the real risk probably isn’t yet so easy to grok, just because we have little understanding yet of the extent of the impact that widespread use of LLMs across our daily and online lives will have.

One key area where they’re already having and are bound to have much more of an impact is user-generated content. We’ve seen companies already deploying first-party integrations that start to embrace some of these uses, like Artifact with its AI-generated thumbnails for shared posts, and Meta adding chatbots to basically everything. Musk is debuting Grok on X as a feature reserved for Premium+ subscribers initially, with a rollout supposedly beginning this week.

Has OpenAI invented an AI technology with the potential to “threaten humanity”? From some of the recent headlines, you might be inclined to think so.

Reuters and The Information first reported last week that several OpenAI staff members had, in a letter to the AI startup’s board of directors, flagged the “prowess” and “potential danger” of an internal research project known as “Q*.” This AI project, according to the reporting, could solve certain math problems — albeit only at grade-school level — but had in the researchers’ opinion a chance of building toward an elusive technical breakthrough.

New research suggests that biological age, as indicated by DNA methylation, more significantly impacts cognitive abilities like memory and processing speed than chronological age. This finding could reshape our understanding of aging and cognitive health.

A year has passed since NASA’s Artemis I mission sent the new Orion spacecraft all the way to the moon, and then beyond, setting a new record in the process.
