FIFA and pop superstars should discount tickets for fans to keep climate costs of 'mega-events' down, say researchers‎

The vast majority of carbon emissions caused by "mega-events" such as World Cups and global concert tours come from audience travel, according to University of Cambridge researchers. In a new study, researchers estimate that expanding to 48 teams for this year's World Cup increased emissions by well over half a million metric tons to some 4.23 million metric tons of carbon for the whole tournament, 82% of which comes from traveling fans, with around 3 million metric tons from flying alone.

Frog protein could become first antidote to deadly red tide toxin‎

The "red tide" algal blooms that are becoming more frequent along the Pacific coast produce one of the most potent neurotoxins known: saxitoxin, or STX. The toxin accumulates in shellfish and causes paralytic shellfish poisoning (PSP) when consumed.

Understanding Bavaria's Indigeneity‎

When I tell people that I am a proud Boarisch-Schwob—Bavarian-Swabian—Indigenous person, I am often met with disbelief. I am white. I am European. I come from Bavaria, one of Europe's wealthiest regions. For some people, those facts settle the question before I have explained anything else.

When disaster strikes, people often flee to places that feel familiar‎

When the Marshall Fire tore through suburban Colorado in late 2021, residents had only hours to decide where to go. Some fled to nearby towns. Others stayed farther away for weeks or months. Now, a recent study published in Humanities and Social Sciences Communications suggests those decisions were shaped not only by distance or danger but also by something more human: the pull of familiar communities and social ties.

To measure a black hole's ultimate spin, we have to go to space‎

Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quickly is key to understanding how they affect their immediate vicinity and the galaxies that surround them. A new paper by Tegan Thomas of the University of Virginia and her colleagues, available on the arXiv preprint server, has good news and bad news on that front. The bad news is that we currently can't determine how fast black holes are actually spinning. The good news is that, hopefully in the next few years, we will have a new tool that will allow us to do so.
