The human heart shows signs of ageing after just a month in space
NASA astronauts Sunita Williams and Butch Wilmore are stuck on the ISS for months because of technical issues with Boeing’s Starliner spacecraft.Credit: NASA via AP/Alamy Over the course of just one month in space, engineered human heart tissue got weaker, its ‘beating’ patterns became irregular and it underwent molecular and genetic changes that mimicked the […]

Two kinds of LLM responses: Informational vs. Instructional
When thinking of LLM evals especially in the context of RAGs, it occurred to me that there are two kinds of distinct responses people get from LLMs: informational and instructional. While the difference may seem trivial, I think it has strong implications on evals. Most commonly available datasets like MMLU, GSM8k etc. are ridiculously small […]
Ocean waves grow way beyond known limits
Credit: University of Edinburgh Scientists have discovered that ocean waves may become far more extreme and complex than previously imagined. The new study, published in Nature today, reveals that under specific conditions, where waves meet each other from different directions, waves can reach heights four times steeper than what was once thought possible. It has […]

Averaging is a convenient fiction of neuroscience
At any social gathering of neuroscientists, the conversation can turn to what’s holding back the field. “Funders,” some grumble, lamenting the amount of money thrown at microbiology instead. “Journals,” others chip in, grousing at the gatekeeping editors who stop new ideas from flourishing. “The tyranny of old-timers,” some newly minted principal investigator often mutters, cursing […]
Perfect prevention vs. perfect detection
Consider the spectrum of strictness – on the low end, Apple’s ScreenTime exemplifies a comically low hurdle to bypassing self-enforced constraints. One button press and you’re back to whatever presumably counterproductive activity you were doing before you used up your budget. On the high end, Clearspace has a mode that will require 10 pushups for […]
Inside a Ferroelectric RAM Chip
Ferroelectric memory (FRAM) is an interesting storage technique that stores bits in a special “ferroelectric” material. Ferroelectric memory is nonvolatile like flash memory, able to hold its data for decades. But, unlike flash, ferroelectric memory can write data rapidly. Moreover, FRAM is much more durable than flash and can be be written trillions of times. […]
Octopuses seen hunting together with fish, punching those that don’t cooperate
The Summary A new study found that some members of an octopus species hunt cooperatively in groups with fish. Video shows octopuses punching their companion fish to keep them on task and contributing to the hunt. The findings indicate that some octopuses have richer social lives than scientists previously understood. Octopuses don’t always hunt alone […]
