The United States government's recent release of hundreds of previously classified unidentified anomalous phenomena (UAPs) cases spanning the 1940s to the present, along with the new Steven Spielberg movie, "Disclosure Day," about extraterrestrial life, has fueled the idea that aliens are visiting Earth.
Science and fiction have their say on UFO ‘Disclosure Day’
"Disclosure Day" is nigh!
We're not talking about end times for UFO believers, but about this week's debut of Steven Spielberg's latest movie about space aliens.
"Disclosure Day" is something of a second coming for the c

Quit praying for a giant meteor to fix our problems here on Earth. It's much better to pray for comet Bernadelli-Bernstein: the Solar System's largest comet ever

How our #cells evolved: #Genome analysis rewrites the origin of the first #eukaryotes
Using the MareNostrum supercomputer, researchers at BSC-CNS and IRB Barcelona discover that the first complex cells emerged from a gradual, millions-year alliance involving giant #viruses and multiple bacterial groups
Published in Nature, the team led by Dr. Toni Gabaldón used the MareNostrum supercomputer to reconstruct the genetic origin of the last common ancestor of all eukaryotes—the cellular lineage to which animals, plants, fungi, and protists belong. The study challenges the idea that cellular complexity emerged from a single evolutionary encounter, pointing instead to a gradual process of interactions among different microorganisms that lasted for millions of years. The findings, which culminate more than five years of computational work, identify contributions from several bacteria in addition to the one that gave rise to mitochondria, and suggest that giant viruses may have acted as vehicles for gene transfer.

The deep sea is a unique ‘evolutionary engine’ with one of the richest and most unexplored sources of genetic diversity on Earth, according to a major new study that has assessed its potential to transform biotechnology and DNA sequencing technologies.
Every time scientists talk about life beyond Earth, audience questions range from profound to unexpected. Here are honest, up-to-date answer to 10 of the biggest ones

Astronomers have revealed distinct differences in atmospheric conditions between the morning and evening transition zones of the ultra-hot gas planet WASP-121 b, which separate day from night, commonly called terminators. This achievement was only possible due to the unmatched sensitivity of the James Webb Space Telescope (JWST).
When a scientific controversy or breakthrough dominates headlines, press officers and journalists often quote a handful of experts.
These views may be insightful, but they rarely tell us what the wider scientific community thinks.
And yet public discussions frequently rely on phrases such as “the science says” or “scientists believe”, as if there were a clear and measurable answer.
In reality, systematic evidence about scientific opinion is often missing.
Attempts to find evidence for #life beyond Earth provide fascinating case studies into diversity of scientific opinion.
