Sept 27 - In the world of "Star Trek," the starship Enterprise zips through space using a warp drive that harnesses antimatter. Suffice it to say, such technology remains in the realm of science fiction.
Antimatter is the enigmatic twin of ordinary matter, possessing the same mass but with an opposite electrical charge. Almost all subatomic particles, such as electrons and protons, have an antimatter counterpart. While electrons are negatively charged, antielectrons, also called positrons, are positively charged. Likewise, while protons are positively charged, antiprotons are negatively charged.
"On Earth, most antimatter that occurs naturally is produced from cosmic rays - energetic particles from space - that collide with atoms in the air and create antimatter-matter pairs," said physicist Jonathan Wurtele of the University of California, Berkeley, co-author of the study published in the journalThis newly created antimatter lasts only until it hits a normal matter atom in the lower atmosphere.
"Our experiment rules out other theories that require antimatter to rise - 'anti-gravity' - in the Earth's gravitational field," Wurtele added.

Why Einstein must be wrong: In search of the theory of gravityEinstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities inside black holes—and the Big Bang itself.

Why build megastructures? Just move planets around to make habitable worldsIn 1960, Freeman Dyson proposed how advanced civilizations could create megastructures that enclosed their system, allowing them to harness all of their star's energy and multiplying the habitable space they could occupy. In 2015, the astronomical community was intrigued when the star KIC 8462852 (aka Tabby's Star) began to dim inexplicably. While an analysis of the star's light curve in 2018 revealed that the dimming pattern was more characteristic of dust than a solid structure, Tabby's Star focused attention on the concept of megastructures and their associated technosignatures.

Study shows birds that have evolved greater complexity are less biodiverseA new study of the evolution of birds shows that as their skeletons become more complex, they also decrease in diversity, with fewer species as they become more specialized in their niches. The findings, published in Nature Communications, show a correlation between skeleton complexity and bird diversity for the first time, and help biologists better understand why biodiversity varies across the birds.
