With COVID rates dropping and vaccinations on the rise, the United States and other places are removing some requirements for face coverings. Are they moving too fast?
The recent announcement that scientists have made human-monkey embryos and cultured them in the lab for two weeks made international headlines.
The technology to make animals that contain cells from other species has been available for decades and used extensively in research. These organisms are called “chimeras”.
But this latest advance highlights the need to broaden the discussion around the possible benefits of such research and, specifically, how inter-species chimeric research should be conducted in future.
A team of North Hollywood High School science students emerged victorious Saturday over scholars from 63 other schools nationwide in this year’s U.S. Department of Energy Office of Science National Science Bowl Championship.
The win marks North Hollywood High’s second National Science Bowl championship, following the title captured in 2001.
The school has placed among the top five teams 12 times at the national event.

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.
Some thoughts about the genetic code aliens would use in the 2nd part of the series: The Science of Aliens:
Alien life would likely have different biochemistry, which may change the way it reproduces.
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.

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.”

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.
