This One Planetary Feature May Be Crucial For The Rise of Complex Life in The Universe

This One Planetary Feature May Be Crucial For The Rise of Complex Life in The Universe 9 JULY 2021 The way a planet is tilted on its rotational axis with respect to its orbital plane around a star - what we know as axial tilt - could be key to the emergence of complex life. According to a new study, a modest axial tilt, like Earth s, helps increase the production of oxygen, which is vital for life as we know it - and planets with tilts that are too small or too large might not be able to produce enough oxygen for complex life to thrive.

The histones of secret roles were played out in complex cell evolution

The histones of secret roles were played out in complex cell evolution that’s why Tobias Warnecke, Who studies histone archaea at Imperial College London, believes that “something special must have happened at the dawn of eukaryotes, where we go from being simple histones … to octamer nucleosomes. They seem to be doing something qualitatively different.” That, however, is still a mystery. In archaeal species, “there are quite a few that have histones and there are other species that don’t have histones. And those with histones also change a lot,” Warneck said. Last December, he published a paper multiple variants of histone proteins with different functions. Histone-DNA complexes vary in DNA stability and affinity. But they are not as stable or regularly arranged as eukaryotic nucleosomes.

Yes, exoplanets can have oxygen without alien life

Yes, exoplanets can have oxygen without alien life Exploring the wonders of the Cosmos, one mystery at a time. Exploring the wonders of the Cosmos, one mystery at a time. The discovery of life on another world would be a monumental moment in the history of human civilization. The most likely way we will, one day, find alien life will be discovering chemical markers of life in the atmosphere of planets orbiting distant stars. One of these markers is oxygen, which currently makes up a little over 20 percent of the atmosphere of our own world. However, our own world held onto relatively little oxygen until 2.4 billion years ago, when oxygen-producing cyanobacteria filled the atmosphere with the gas, leading to the first widespread extinction â the Great Oxidation event. Many lifeforms on Earth today, including human beings, are now dependent on this life-giving gas.
