UCI researchers: Climate change will alter the position of the Earth’s tropical rain belt
Irvine, Calif. — Future climate change will cause a regionally uneven shifting of the tropical rain belt – a narrow band of heavy precipitation near the equator – according to researchers at the University of California, Irvine and other institutions. This development may threaten food security for billions of people. In a study published today […]
Difference by the year 2100 expected to impact global biodiversity, food security — ScienceDaily
Future climate change will cause a regionally uneven shifting of the tropical rain belt — a narrow band of heavy precipitation near the equator — according to researchers at the University of California, Irvine and other institutions. This development may threaten food security for billions of people. In a study published today in Nature Climate […]
Glass frogs living near roaring waterfalls wave hello to attract mates
Berkeley — Most frogs emit a characteristic croak to attract the attention of a potential mate. But a few frog species that call near loud streams — where the noise may obscure those crucial love songs — add to their calls by visually showing off with the flap of a hand, a wave of a […]
Stuck in a rut: Ocean acidification locks algal communities in a simplified state
IMAGE: Image photo of algal communities view more Credit: University of Tsukuba Tsukuba, Japan – Out with the old, in with the new, as the New Year’s saying goes, but not where the marine environment is concerned. Researchers from Japan have discovered that ocean acidification keeps algal communities locked in a simplified state of low biodiversity. […]
Guppies have varying levels of self-control
IMAGE: Trinidadian guppies view more Credit: University of Exeter Just like humans trying to stick to New Year’s resolutions, guppies have varying levels of self-control, a new study shows. Researchers from the University of Exeter and Ghent University studying the behaviours of Trinidadian guppies tested “inhibitory control” (suppressing unhelpful impulses or urges). The tiny fish first […]
Like plants do: non-classical photosynthesis by earth’s inorganic semiconducting minerals
IMAGE: Earth-abundant minerals convert sunlight into chemical energy, hinting at the evolution of photosynthesis in early bacteria view more Credit: Earth Science Frontiers Photosynthesis, the process by which plants and other organisms convert sunlight into chemical energy, has been a major player during the evolution of life and our planet’s atmosphere. Although most of the ins […]
Scientists discover bizarre new mode of snake locomotion

Peter Raven addresses earth’s dwindling resources, the value of science-informed outreach
The BioScience Talks podcast features discussions of topical issues related to the biological sciences. In a career-spanning installment of the journal BioScience‘s In Their Own Words oral history series, Missouri Botanical Garden President Emeritus Peter Raven illuminates numerous topics, sharing insights related to the sustainability of human civilization, the COVID-19 pandemic, and the importance of […]
