Hey ChatGPT, write me a fictional paper: these LLMs are willing to commit academic fraud Mainstream chatbots presented varying levels of resistance to deliberate requests for fabrication, study finds.

The findings “should act as a wake-up call to developers on how easy it is to use LLMs to produce misleading and low-quality scientific research”

Mike's latest COVID-19 Heat Map is up. To fellow New Yorkers: 1 in 39 people are estimated to be actively infectious. Mask up, and increase ventilation to the extent feasible when indoors.

A graph titled "Sleep Patterns Among High School Students in the US" from JAMA shows sleep duration trends from 2007-2023. "Insufficient Sleep Among US Adolescents Across Behavioral Risk Groups" is written on the top. There are lines for <5h, 6-7h, and >=8h.

Insufficient #sleep among US high school students increased from 2007 to 2023, with the rise driven largely by more adolescents reporting very short sleep durations of ≤5 hours per night.

Active v. Latent TB: What to Know About the San Francisco Outbreak In the wake of a recent outbreak of tuberculosis (TB) and latent TB cases at a local San Francisco high school, IGHS's Priya Shete tells us what to know about latent TB.

A tuberculosis outbreak caused numerous cases of latent TB, a dormant form of the infection. While latent TB is symptom-free & non-contagious, it can “wake up” into a possibly deadly disease, making screening & preventive treatment critical, Dr. Priya Shete explains. https://ucsfh.org/4kGQHmy

This AI-generated podcast network publishes 11,000 episodes a day. It also ripped off media outlets Daily News Now tops search results for local news podcasts with AI content

NEW on @indicator.media:

I found an AI-generated podcast network that has published 350,000 episodes in the past month. That's 11,000 episodes a day, or about one year's worth of audio content.

You'll be shocked to find out it's not generating original material.

Community health project in Kenya and Uganda dramatically cuts new HIV infections Large-scale study finds that simplifying delivery of prevention medication and improving connections to clinics is key

Study in 80,000 people in Uganda and Kenya shows 70% reduction in risk of HIV infection. The secret? Community health workers offering testing at home, simplified access to PrEP and PEP, follow up with smart phone app that connects people to clinics. Remarkable.

1. Time for a #flu & #measles update.
Six more kids have died from flu, bringing the year-to-date total to 66. Sadly there will be more deaths reported but hopefully this year doesn't approach last year's dreadful pediatric death toll. #CDC estimates ~90% of these kids weren't vaccinated.

A year ago, I thought LLMs were kind of neat but not that useful. I saw the code autocomplete and thought, meh.

Last summer just flipped. I never ever thought I would see automated code generation like we see now.

I know there’s baggage but you need to know the coders are being real about this
