Evolution is evolving: 13 ways we must rethink the theory of nature

Do species really exist? Are genes destiny? Do only the fittest survive? Can we shape or stop evolution? New insights into nature are providing surprising answers, and a glorious new picture of life’s complexity Source: https://www.newscientist.com/article/mg24733010-800-evolution-is-evolving-13-ways-we-must-rethink-the-theory-of-nature/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Giant ‘survivor’ planet found orbiting dead star

For the first time, astronomers have detected a planet orbiting a white dwarf star. If further confirmed, the discovery shows that some planets could survive the destruction of their sun-like stars, and some might even remain potentially habitable.

Can life survive a star’s death? Webb telescope can reveal the answer

When stars like our sun die, all that remains is an exposed core—a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its star, according to Cornell University researchers.

Has microbial life been found on Venus?

Is there microbial life in the atmosphere of Earth’s closest neighbor, Venus? An international team of astronomers has found tentative but highly compelling evidence. Source: https://earthsky.org/space/life-on-venus-phosphine-biosignatures…

The Case for Life on Venus

CNET describes Venus as “a toxic, overheated, crushing hellscape where nothing can survive.” But they reported Friday that one astronomy team’s hypothesis published last month “could prompt a reevaluation of how and where we look for life in the universe.” Carl Sagan speculated about life in the clouds of Venus back in 1967, and just a few years ago, researchers suggested…

Remembering Laika: ‘Space Dogs’ Documentary Explores Moscow Through a Stray’s Eyes

Space.com reports:
Laika, a stray dog scooped off the streets of Moscow, launched on the Soviet Union’s Sputnik 2 mission in November 1957, just a month after Sputnik 1’s liftoff opened the space age. The 11-lb. (5 kilograms) mixed-breed quickly died of overheating and circled Earth as a corpse until April 1958, when Sputnik 2 fell back into the atmosphere and burned…

Nearby red dwarf star not so quiet and life-friendly after all

Astronomers say the nearby red dwarf star Gliese 887 appears to have more dangerous flare activity than first believed. This could make life tough – but maybe not impossible – on its family of super-Earth planets. Source: https://earthsky.org/space/red-dwarf-gliese-887-flares-in-ultraviolet-light…

How ancient proteins are untangling humanity’s family tree

We can’t extract DNA from some of the most perplexing ancient human fossils.

Bacteria From Earth Can Survive In Space and Could Endure the Trip To Mars, Says Study

AmiMoJo shares a report from CNN: A type of bacteria that is highly resistant to radiation and other environmental hazards survived outside of the International Space Station for three years, according to a new study. The Japanese Tanpopo mission involved including pellets of dried Deinococcus bacteria within aluminum plates that were placed in exposure panels outside of the space station. Deinococcus…

Bacteria could survive travel between Earth and Mars when forming aggregates

Imagine microscopic life-forms, such as bacteria, transported through space, and landing on another planet. The bacteria finding suitable conditions for its survival could then start multiplying again, sparking life at the other side of the universe. This theory, called “panspermia”, support the possibility that microbes may migrate between planets and distribute life in the universe. Long controversial, this theory implies that…
