Researchers were studying the X-rays flaring from a supermassive black hole in the center of the spiral galaxy, Zwicky 1, 800 million light-years away when they discovered the unexpected phenomenon.

Vaccines continue to be highly effective, especially at preventing severe illness and death, but may be less effective at preventing infection or transmission of the delta variant, according to the internal report.

The analysis shows that some of the cathedral's stained-glass windows could date as far back as the mid-1100s. As such, the windows may have overlooked the murder scene of Thomas Becket, the archbishop of Canterbury who was slain at the cathedral's altar by soldiers loyal to Henry II in 1170.

The results suggest that these bacteria, and the specific compounds they produce, known as secondary bile acids, could contribute to a healthy gut and, in turn, healthy aging.

But just what are these potato-shaped chunks of rock, and what are the odds that one could hit Earth sometime in the near future? "You can think about asteroids as planets that didn't make it," Federica Spoto, a research scientist at the Minor Planet Center, an institute that studies small bodies, told Live Science. "They are what's left over from the origin of the solar system." Full Story: [LiveScience]( (7/30) [LinkedIn]( [Twitter]( [Facebook]( [Email]( [] That’s Strange! [] [Strange DNA 'borgs' discovered in California]( [Strange DNA 'borgs' discovered in California]( (PublicDomainPictures/Pixabay Images) Scientists accidentally discovered a mysterious -- and unusually large -- DNA structure deep in the mud in California wetlands. The structure, known as a "Borg," likely belongs to a single-celled organism and carries many genes that are unknown to science. It's not totally clear what these massive strings of DNA do, but they may help supercharge the organisms' ability to break down chemicals in the soil. "Imagine a strange foreign entity, neither alive nor dead, that assimilates and shares important genes," said senior author Jillian Banfield, a geomicrobiologist at UC Berkeley.
