Researchers have long observed that a common family of environmental bacteria, Comamonadacae, grow on plastics littered throughout urban rivers and wastewater systems.

Finding could lead to bioengineering solutions to clean up plastic waste.

A new study finds that a common bacterium can break down plastic for food, opening new possibilities for bacteria-based engineering solutions to help clean up plastic waste. Illustration credit Ludmilla Aristilde/Northwestern University.

We’re not actually specifically focused on AGI.

I’m simply saying that AGI seems likely to be an emergent property of what we’re doing, because we’re creating all these autonomous cars and autonomous humanoids that are actually a truly gigantic data stream that’s coming in and being processed.

This is about life expectancy, not radical life extension.

A new study has suggested that radical life extension is all but impossible in this century [1], and it has made waves among people interested in living longer.

A paper titled “Implausibility of radical life extension in humans in the twenty-first century” was destined to ignite controversy in the longevity community. Published in Nature Aging, it lists Jay Olshansky as its corresponding author, a renowned researcher who has been studying the populational dynamics of life expectancy for decades. We delved deeper into this study and reached several prominent community members for comments.

I’ve been having the most insane dreams recently…

Scientists have brought science fiction one step closer to reality by achieving the first two-way communication between individuals during lucid dreaming, Report informs referring to the Daily Mail.

In an experiment that sounds like a scene out of the movie ‘Inception,’ REMspace — a California-based startup that designs technology to enhance sleep and lucid dreaming — reportedly exchanged a message between two people who were asleep.

A Ludwig Cancer Research study has punctured a longstanding assumption about the source of the most common type of DNA mutation seen in the genome—one that contributes to many genetic diseases, including cancer.

Led by Ludwig Oxford Leadership Fellow Marketa Tomkova, postdoc Michael McClellan, Assistant Member Benjamin Schuster-Böckler and Associate Investigator Skirmantas Kriaucionis, the study has implications not only for basic cancer biology but also for such things as assessments of carcinogenic risk associated with environmental factors and our understanding of the emergence of drug resistance during cancer therapy. Its findings are reported in the current issue of Nature Genetics.

The mutation in question—in which cytosine ©, one of the four bases of DNA that spell out our genes, is erroneously switched to thymine (T)—was thought to be primarily the result of a spontaneous chemical reaction with water. This reaction, deamination, is about twice as likely to happen when a cytosine is chemically tagged by the addition of a molecule known as a methyl group to create 5-methylcytosine, which occurs in DNA at so-called “CpG” positions, where C is followed by the base guanine (G).

The newly-discovered isotope, plutonium-227, has a half-life of 0.78 seconds, according to a team of physicists from China.
