Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth – and it could help assess which other planets can develop life, ranging from plants to animals and humans.

The study, published today in Nature Geoscience and led by a researcher at the University of Bristol, reveals for the first time how the build up of carbon-rich rocks has accelerated oxygen production and its release into the atmosphere.

Until now the exact nature of how the atmosphere became oxygen-rich has long eluded scientists and generated conflicting explanations.

What do you imagine when I say the future of human evolution?

Charles Darwin and his followers postulated that random accidental mutations of small effect plus natural selection over long periods would provide sufficient hereditary variation to explain biological diversity. Research since the middle of the twentieth century has unexpectedly shown that living organisms possess many different means of altering their genomes biologically, and these processes have been validated by DNA sequence analysis. In addition, the biological process of interspecific hybridization has become recognized as a major source of rapid speciation and genome amplification. Thus, it is time to shift our basic concept of evolutionary variation from the traditional model of slow change from non-biological sources to a fully biological model of rapid genome reorganization stimulated by challenges to reproduction.

Introduction

In Western society prior to the Enlightenment, there was little disagreement about the origins of biological diversity: it resulted from divine creation of an unchanging panorama of plant and animal species, as explained in Genesis. No thought was given to the idea that living organisms could change their fundamental natures. Even a scientist dedicated to analyzing the nature and classification of life forms, Carl Linnaeus (1707−1778), and one who documented the extinction of fossil organisms, Georges Cuvier (1769−1832), both believed in the fixity of species.

We’re now adding a new location and entering into the next stage of the program’s evolution. Later this year, drone deliveries are coming to the West Valley of the Phoenix Metro Area in Arizona.

With this new location, we’ll be fully integrated into Amazon’s delivery network, meaning, for the first time, drones will deploy from facilities next to our Same-Day Delivery site in Tolleson. These smaller sites are hybrid—part fulfillment center, part delivery station. They allow us to fulfill, sort, and deliver products all from one site so we can get packages out to our customers even quicker. Our Same-Day Delivery sites are situated close to the large metro areas they serve, which means customers get their orders faster. And with connections to the larger Amazon fulfillment centers nearby, we are able to offer Same-Day Delivery on millions of items.

We’re currently working with the Federal Aviation Administration (FAA) and local officials in Tolleson to obtain all necessary permissions to conduct these deliveries in Tolleson. Once we’ve received all the necessary approvals, we’ll begin reaching out to customers in the West Valley so they can receive drone deliveries when the service goes live later this year.

Scientists champion global genomic surveillance using the latest technologies and a ‘One Health’ approach to protect against novel pathogens like avian influenza and antimicrobial resistance, catching epidemics before they start.

The COVID-19 pandemic turned the world upside down. In fighting it, one of our most important weapons was genomic surveillance, based on whole genome sequencing, which collects all the genetic data of a given microorganism. This powerful technology tracked the spread and evolution of the virus, helping to guide public health responses and the development of vaccines and treatments.

But genomic surveillance could do much more to reduce the toll of disease and death worldwide than just protect us from COVID-19. Writing in the journal Frontiers in Science, an international collective of clinical and public health microbiologists from the European Society for Clinical Microbiology and Infectious Diseases (ESCMID) calls for investment in technology, capacity, expertise, and collaboration to put genomic surveillance of pathogens at the forefront of future pandemic preparedness.

The universe is still expanding at an accelerating rate, but it may have slowed down recently compared to a few billion years ago, early results from the most precise measurement of its evolution yet suggested Thursday.

While the preliminary findings are far from confirmed, if they hold up it would further deepen the mystery of dark energy—and likely mean there is something important missing in our understanding of the cosmos.

These signals of our universe’s changing speeds were spotted by the Dark Energy Spectroscopic Instrument (DESI), which is perched atop a telescope at the Kitt Peak National Observatory in the US state of Arizona.

I found this on NewsBreak:

The crew of the International Space Station has stumbled upon a drug-resistant bacteria on board, leaving them baffled as to how it arrived.

Scientists working in the low orbit lab have confirmed the discovery, which raises concerns about the potential evolution of more robust bacteria that could defy current treatments. The unique microgravity environment of the ISS is suspected to be a factor in the bacteria’s persistence.

Thanks to the dizzying growth of cosmic observations and measurement tools and some new advancements (primarily the “discovery” of what we call dark matter and dark energy) all against the backdrop of General Relativity, the early 2000s were a time when nothing seemed capable of challenging the advancement of our knowledge about the cosmos, its origins, and its future evolution.

From house plants and gardens to fields and forests, green is the color we most associate with surface life on Earth, where conditions favored the evolution of organisms that perform oxygen-producing photosynthesis using the green pigment chlorophyll a.
