He is emeritus visiting professor in physics at the University of Oxford. He is the author of Absolute or Relative Motion?, The End of Time, and The Janus Point. Barbour’s work on time has forcused on the illusion of time. He argues, time as such does not exist but only change. He has shown how, alongside the relativity of motion, the notion of time as change can be built into the foundations of dynamics and looked at the consequences of this implication for the quantum mechanics of the universe.

These soft robots can do the butterfly stroke.

A team of scientists at North Carolina State University (NCSU) has developed two butterfly-shaped soft robots capable of swimming at 1.70 and 3.74 body lengths per second (BL/s). They are being referred to as the fastest swimming soft machines in the world because until now, soft robots were known to swim at a maximum speed of one body length per second.

One of the authors and the associate professor at NCSU, Jie Yin told IE, “The connection has not been built until my kids went to the swimming school and learned the butterfly stroke. The butterfly stroke is a very fast swimming technique that requires an undulating body and also rotating and flapping arms.”

The California PUC granted Waymo a permit to operate 24 hours/day in San Francisco taking select members of the public for rides with no safety driver in the vehicle. Waymo says it will begin this shortly. This comes on the heels of them expanding such service in Phoenix, as reported in my article on how the death of self-driving cars has been greatly exaggerated earlier this week.

This service will be with “trusted testers” rather than members of the broad public that can ride in Chandler and Phoenix, Arizona.


Waymo gets a permit to take the public and will start running with trusted testers. They also start in LA and show off their new robotaxi. Cruise also ups its game. Zoox got into an accident but it was in manual. Aurora reminds us they do more than trucks.

The patients wake up from anaesthesia with the cancer treated.

There’s a new robotic technology that finds lung cancer early and also has the ability to treat it at the same time, according to a report by CBS Philadelphia.

The American Lung Association’s annual report revealed that lung cancer survival rates are on the rise thanks partially to this new technology. The five-year survival rate is now estimated at 25%.

One example of this success is Kathleen McGinn, who found her cancer early and treated it with the new robotic procedure. “I’m very optimistic for my future,” McGinn told CBS.

A mechanism has been discovered that regulates cellular levels of tau, a protein whose aberrant accumulation is at the root of tauopathies, a class of devastating neurodegenerative diseases.

The finding was discovered in the laboratory of Michel Cayouette, director of cellular neurobiology research at the Montreal Clinical Research Institute (IRCM) and a medical professor at the University of Montreal.

The research, which was recently published in the journal Science Advances, demonstrates how the protein known as ‘numb’ regulates intracellular tau levels, making numb a potential therapeutic agent for tauopathies.

Back pain is a common condition with numerous causes, including poor posture, overexertion, constant stress at work or at home, lack of exercise, and poor posture. For a considerable number of patients, the symptoms are chronic, meaning they last a long period or reoccur repeatedly. However, port and exercise therapy, when done properly, can provide alleviation.

Physiotherapy, as well as strength and stability exercises, are common treatment options. But how can the treatment be as effective as possible? Which method reduces pain the most effectively? A recent meta-analysis published in the Journal of Pain by Goethe University Frankfurt revealed new insights.

The researchers began with data from 58 randomized controlled trials (RCTs) involving over 10,000 individuals suffering from chronic low back pain throughout the globe. The relevant data from the original manuscripts were first filtered out and then analyzed in groups. When analyzing this data, the researchers looked at whether and how conventional forms of therapy and individualized treatment varied in terms of outcome. “Individualized” refers to some kind of personal coaching where therapists precisely target the needs and potentials of each patient and collaborate with them to choose the course of their treatment.

To show how computer chips are improving a bit, my first computer, an Apple II+ based on the 6,502 chip, had 7 bytes of memory on the chip. Nvidia’s H100 chip has 85,986,377,728 bytes of memory on it!

The 6,502 was a very successful chip and is still made today, with over 6 billion units sold!

(My home PC has about 283,506,646,208 bytes of memory but that is contained in multiple chips.)
