New work extends the thermodynamic theory of computation
In a paper published in Physical Review X on May 13, a quartet of physicists and computer scientists expand the modern theory of the thermodynamics of computation. By combining approaches from statistical physics and computer science, the researchers introduce mathematical equations that reveal the minimum and maximum…

Engines of Evidence – A Conversation with Judea Pearl
In the early 1960s, every company had a huge investment in the future of computers. I fell into a device-oriented research group, wherein the goal was to find new phenomena that we could turn into computer memory. Magnetic core memories were already becoming a nuisance. Some people worked on photochromic phenomena…

Geneticists develop novel gene therapy for glaucoma
The gene therapeutic approach, which shows promise for treating age related macular degeneration (AMD), may also be effective in treating other eye conditions such as glaucoma. It provided benefit in three additional models of mitochondrial dysfunction, including cells taken from patients living with an optic…

No increased risk of brain tumours for mobile phone users, new study finds
Longstanding fears that using mobile phones may increase the risk of developing a brain tumour have been reignited recently by the launch of 5G (fifth generation) mobile wireless technologies. Mobile phones emit radiofrequency waves which, if absorbed by tissues, can cause heating and damage.

Initial Covid-19 infection rate may be 80 times greater than originally reported
A new study from Penn State tracked excess influenza-like illness data from the Centers for Disease Control and Prevention to estimate that the number of early COVID-19 cases in the U.S. may have been more than 80 times greater and doubled nearly twice as fast as originally believed.

Is Faster-Than-Light Travel or Communication Possible? (1997)
It might be thought that special relativity provides a short negative answer to this question. In actual fact, there are many trivial ways in which things can be going faster than light (FTL) in a sense, and there may be other more genuine possibilities. On the other hand, there are also good reasons to believe that…

Just how bad are we at treating age-related diseases?
Whether you believe in preventing damage (the core aim of the aging field, though that's not the focus of this post) or treating damage as it arises, our current best efforts in both treatment and mechanism selection haven't yielded promising results. None of the approved drugs for age-related diseases reverse any…
