Perseverance’s Robotic Arm Starts Conducting Science Program

Posted by in categories: biological, robotics/AI, science, space

NASA’s newest Mars rover is beginning to study the floor of an ancient crater that once held a lake.

NASA’s Perseverance rover has been busy serving as a communications base station for the Ingenuity Mars Helicopter and documenting the rotorcraft’s historic flights. But the rover has also been busy focusing its science instruments on rocks that lay on the floor of Jezero Crater.

What insights they turn up will help scientists create a timeline of when an ancient lake formed there, when it dried, and when sediment began piling up in the delta that formed in the crater long ago. Understanding this timeline should help date rock samples – to be collected later in the mission – that might preserve a record of ancient microbes.

The Science of Consciousness: Towards the Cybernetic Theory of Mind

Posted by in categories: biological, information science, robotics/AI, science

Consciousness remains scientifically elusive because it constitutes layers upon layers of non-material emergence: Reverse-engineering our thinking should be done in terms of networks, modules, algorithms and second-order emergence — meta-algorithms, or groups of modules. Neuronal circuits correlate to “immaterial” cognitive modules, and these cognitive algorithms, when activated, produce meta-algorithmic conscious awareness and phenomenal experience, all in all at least two layers of emergence on top of “physical” neurons. Furthermore, consciousness represents certain transcendent aspects of projective ontology, according to the now widely accepted Holographic Principle.

Intermittent Fasting for Longevity: The Science Behind the Hype

Posted by in categories: biotech/medical, food, life extension, science

Mice fed every other day in another study lived, on average, 12% longer than mice fed every day, largely due to the delay of cancerous diseases.

According to the International Food Information Council’s 2020 Food and Health Survey, you most likely know someone who is practicing intermittent fasting. The survey of 1000 adult Americans found that one in ten were putting down the fork during specified periods of time, making it America’s most popular “diet.”

Ancient Bear DNA Sequenced From Old Cave Dirt in Historic First For Science

Posted by in categories: biotech/medical, science

The dirt scattered across the floor of an ancient, remote cave in Mexico has yielded a new source of viable ancient DNA.

For the first time, scientists have sequenced ancient DNA from soil samples — and it’s all thanks to the Upper Paleolithic bears that prolifically used the cave as their toilet around 16000 years ago.

The scientists describe their work as “the Moon landing of genomics”, as the breakthrough means fossilized remains are no longer the only way of obtaining ancient DNA. Further, it shows ancient DNA can now be studied in the context of populations, rather than scattered, fragmentary individuals.

A guide to Plan S: the open-access initiative shaking up science publishing

Posted by in category: science

As the first papers under these mandates are published, Plan S supporters say it’s the start of a journey towards open science. But most research funders haven’t signed up yet, and negotiations over the plan have produced a complex landscape of options to avoid paywalls. Here’s what the initiative means for scientists and journals — and some of the controversies that will play out in 2021 and beyond.


The push to remove journal paywalls officially started this year. Here’s how it works.

Fat and Healthy? What the Science Says About Longevity and Weight

Posted by in categories: biotech/medical, life extension, science

Given the rate of overweight and obese people in the Western world, there are inevitably lots of fat people interested in life extension. Assuming that weight-loss trends continue with a high failure rate, the majority of fat spanners will not be able to lose and maintain their weight loss through diet and exercise.

This article explores effective life-extension interventions that do not include weight loss for people with an excess of adipose tissue.


Is it possible to be fat and healthy? Is obesity a death sentence? Learn about what the science says about life extension when fat.
