@DrAkhilX Dear Dr. Akhil, yesterday afternoon I took an Advil to ease period pain. The pill first stuck in my throat, so I drank water to send it down. However, I had been feeling slight irritation since then. Today I woke up with intense pain. It feels like Tonsillitis. What should I do?

[Dr. AK 🇮🇳 @docakx]

This man swallowed an antibiotic pill without water at bedtime and woke up with severe chest pain & vomiting.

Endoscopy showed pill fragments stuck in the food pipe causing extensive damage -condition called pill-induced esophagitis which can cause permanant damage.

Caused by Doxycycline pill in this case. List of medications that can cause this👇

Antibiotics: Tetracyclines (especially doxycycline, which is the most frequent), clindamycin, amoxicillin, metronidazole, ciprofloxacin, and rifaximin.

Nonsteroidal anti-inflammatory drugs (NSAIDs): Aspirin and aceclofenac.

Bisphosphonates: Alendronate and ibandronate (risedronate may be slightly less risky).

Other agents: Potassium chloride, ferrous sulfate, ascorbic acid, acetaminophen, warfarin, quinidine, and certain chemotherapeutics like dactinomycin, bleomycin, and methotrexate.

To avoid 💊pill-induced esophagitis, follow these easy steps to help pills pass quickly and safely through your esophagus:

-Drink plenty of water—at least a full glass (200-250 mL or more) when taking the pill.

-Stay upright (sit or stand) for at least 30 minutes after swallowing; don't lie down right away.

-Don't take pills just before bed; wait at least 30 minutes before lying down.

-If you're at higher risk (like elderly or have swallowing problems), ask for liquid versions, IV options, or less irritating alternatives.

-Always follow the specific instructions for the medication (e.g., take bisphosphonates on an empty stomach with water and stay upright).

-Have a small snack or meal after taking the pill to help push it down.

Gotta think about what industrial research is really for and what a supermarket is not for. I hope somewhere there’s a gut microbiologist studying the impact of purslane/verdolaga/kulfa/马齿苋 on the gut–brain axis and on longevity.

Astrocytes have long been conceived as passive support player cells in the brain. But today @ScienceMagazine (via 3 reports) they got a big upgrade for their active role in neuromodulation and control of brain function

GPT-like models trained with bio data (mostly RNA) are likely to learn correlation patterns and make useful interpolations (predictions).

Since their correlative patterns reflect indirect correlations, extrapolations should be interpreted with caution.

[Gavin Baker @GavinSBaker]

1) DeepSeek r1 is real with important nuances. Most important is the fact that r1 is so much cheaper and more efficient to inference than o1, not from the $6m training figure. r1 costs 93% less to *use* than o1 per each API, can be run locally on a high end work station and does not seem to have hit any rate limits which is wild. Simple math is that every 1b active parameters requires 1 gb of RAM in FP8, so r1 requires 37 gb of RAM. Batching massively lowers costs and more compute increases tokens/second so still advantages to inference in the cloud. Would also note that there are true geopolitical dynamics at play here and I don’t think it is a coincidence that this came out right after “Stargate.” RIP, $500 billion - we hardly even knew you.

Real: 1) It is/was the #1 download in the relevant App Store category. Obviously ahead of ChatGPT; something neither Gemini nor Claude was able to accomplish. 2) It is comparable to o1 from a quality perspective although lags o3. 3) There were real algorithmic breakthroughs that led to it being dramatically more efficient both to train and inference. Training in FP8, MLA and multi-token prediction are significant. 4) It is easy to verify that the r1 training run only cost $6m. While this is literally true, it is also *deeply* misleading. 5) Even their hardware architecture is novel and I will note that they use PCI-Express for scale up.

Nuance: 1) The $6m does not include “costs associated with prior research and ablation experiments on architectures, algorithms and data” per the technical paper. “Other than that Mrs. Lincoln, how was the play?” This means that it is possible to train an r1 quality model with a $6m run *if* a lab has already spent hundreds of millions of dollars on prior research and has access to much larger clusters. Deepseek obviously has way more than 2048 H800s; one of their earlier papers referenced a cluster of 10k A100s. An equivalently smart team can’t just spin up a 2000 GPU cluster and train r1 from scratch with $6m. Roughly 20% of Nvidia’s revenue goes through Singapore. 20% of Nvidia’s GPUs are probably not in Singapore despite their best efforts. 2) There was a lot of distillation - i.e. it is unlikely they could have trained this without unhindered access to GPT-4o and o1. As @altcap pointed out to me yesterday, kinda funny to restrict access to leading edge GPUs and not do anything about China’s ability to distill leading edge American models - obviously defeats the purpose of the export restrictions. Why buy the cow when you can get the milk for free?

Doing good science is 90% finding a science buddy to constantly talk to about the project.

[Prof. Feynman @ProfFeynman]

Did you know that it’s actually possible for you to say, “I don’t know enough about this to have an opinion”

[Itai Yanai @ItaiYanai]

Top 4 things to know about doing science:
1. You need to have someone you can talk to
2. One-on-one discussions are the best
3. Think about discussions as improvisations and use the ‘yes, and’ rule
4. Create a safe space so both of you feel open to saying seemingly silly things
