Why time seems to pass faster as we age
1/ I’ve been mega-obsessed with this feeling. A year as a 36-year-old seems so much shorter as compared to when I was a kid or even as a teen. It seems cosmically unfair – we have fewer years to live, and each year flies by faster. 2/ But, why is that happening? My tentative conclusion is that… Read More

Chronic stress spreads cancer
Stress is inevitable. But too much of it can be terrible for our health. Chronic stress can increase our risk for heart disease and strokes. It may also help cancer spread. How this works has remained a mystery—a challenge for cancer care. Xue-Yan He, a former postdoc in Cold Spring Harbor Laboratory (CSHL) Adjunct…

What made Earth a giant snowball 700M years ago? Scientists have an answer
More than 700 million years ago, planet Earth was plunged into a 57-million-year-long ice age. Australian scientists led by Dr Adriana Dutkiewicz and Professor Dietmar Müller at the University of Sydney now have an answer why this happened.

The world is awful. The world is much better. The world can be much better
It is wrong to think these three statements contradict each other. We need to see that they are all true to see that a better world is possible.

Building an early warning system for LLM-aided biological threat creation
We’re developing a blueprint for evaluating the risk that a large language model (LLM) could aid someone in creating a biological threat. In an evaluation involving both biology experts and students, we found that GPT-4 provides at most a mild uplift in biological threat creation accuracy. While this uplift is not…

Constructing a Four-Point Egg
For reasons beyond the scope of this entry, I have been investigating elliptical and ovoid shapes. The Wikipedia article for Moss’s egg has a link to a tutorial on Euclidean Eggs by Freyja Hreinsdóttir which (amongst other things) describes how to construct the “four point egg”. I think it is a nicer shape than Moss’s…

Researchers demonstrate rapid 3D printing with liquid metal
Liquid metal printing, developed by MIT researchers, rapidly creates 3D metal structures by depositing molten aluminum along into a bed filled with microscopic glass beads. The process can produce low-resolution objects like frames for chairs and tables in minutes.
