In the Fox News interview, Ratcliffe described the sightings this way: “We are talking about objects that have been seen by Navy or Air Force pilots, or have been picked up by satellite imagery, that frankly engage in actions that are difficult to explain, movements that are hard to replicate, that we don’t have the technology for or are traveling at speeds that exceed the sound barrier without a sonic boom.” This advertisement has not loaded yet, but your article continues below. Manage Print Subscription / Tax Receipt.It remains unclear why the sequences were removed from the SRA. This adds to a growing body of evidence that the first human cases of COVID-19 were not associated with the Huanan Seafood Market. The recovered sequences, which were probably collected in January and February 2020, show this to be the case - they are more closely related to the bat viruses than are the sequences from people linked to the seafood market.
That is surprising, says Bloom, because you would expect that viruses from the early stages of Wuhan’s epidemic would be most closely related to SARS‑CoV-2’s relatives that infect bats. But the seafood-market sequences are more distantly related to SARS-CoV-2’s closest relatives in bats - the most likely ultimate origin of the virus - than are later sequences. The earliest viral sequences from Wuhan are from people linked to the city’s Huanan Seafood Market in December 2019, which was initially thought to be where the coronavirus first jumped from animals to people. The recovered data help to solve an evolutionary mystery about the early stages of the pandemic.

He worked out that the data had been removed from the Sequence Read Archive (SRA), a US repository for raw sequencing data.īloom was able to find archived versions of the sequences on cloud servers, recovering data from 50 samples, 13 of which contained enough raw data to generate partial genome sequences ( J. A research paper from May 2020 contained a table of publicly available sequence data, which included entries Bloom had not come across. Jesse Bloom, a viral evolutionary geneticist at the Fred Hutchinson Cancer Research Center in Seattle, Washington, discovered the sequences after searching for genomic data from the pandemic’s early stages. The sequences address an evolutionary conundrum about the early genetic diversity of the coronavirus SARS-CoV-2.

SARS-2-CoV testing in Wuhan, China, where the first cases of COVID-19 were reported. In doing so, the study expands astronomers’ thinking about which stars have “a better-than-average shot of discovering and characterizing the Earth”, says Sofia Sheikh, an astrobiologist at the Berkeley SETI Research Center in California.
With this information, the scientists were able to predict from where Earth was visible over the past 5,000 years or so of human civilization - and from where it will be visible up to 5,000 years into the future. Those aliens would be the natural choice for Earthlings to look for, say the scientists - because they could have already had a chance to spot us, and thus might be primed to receive communications from Earth.Īlthough previous studies have considered this question, this is the first to incorporate the movement of stars as they slide in or out of the narrow slice of the sky that lines up with both Earth and the Sun. “For whom would we be the aliens?” she asks. The work offers a new way of thinking about the search for extraterrestrial life, says Lisa Kaltenegger, an astronomer at Cornell University in Ithaca, New York, who led the analysis. If there are aliens on planets around those stars with at least a similar level of technological advancement to ours, then they would theoretically be able to spot us ( L.
