Researchers have created a method called optovolution that uses light to guide the evolution of proteins with dynamic behaviors. By engineering yeast cells so their survival depended on proteins switching states at the right time, scientists could rapidly select the best-performing variants. The technique produced new light-sensitive proteins that respond...
Scientists discover oxygen tug of war inside plant cells
Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that mitochondria—the cell’s energy generators—can actively pull oxygen away from chloroplasts, the structures responsible for photosynthesis. This previously unknown interaction suggests mitochondria can...
Scientists discover hidden species among Borneo’s “fanged frogs”
DNA is revealing that many animals once thought to be a single species may actually be several hidden ones. But research on Bornean fanged frogs shows the line between species can be blurry—an important challenge when deciding what wildlife needs protection most.
Scientists stunned to find signs of ancient life in a place no one expected
While exploring ancient seabeds in Morocco, scientists discovered strange wrinkle-like textures in deep-water sediments that shouldn’t have been there. These structures are usually made by sunlight-loving microbial mats in shallow waters. But the rocks formed far below the reach of light, suggesting a different explanation. Evidence points to chemosynthetic microbes—organisms...
Scientists finally reveal why mint feels cold
Scientists have revealed how the body’s microscopic cold sensor, TRPM8, detects both chilly temperatures and the cooling effect of menthol. The discovery finally shows how the sensation of “cool” works at the molecular level—and could inspire new treatments for pain and eye disorders.
Bird droppings helped build one of ancient Peru’s most powerful kingdoms
New research suggests seabird guano helped transform the Chincha Kingdom into one of the most prosperous societies in ancient Peru. Chemical clues in centuries-old maize show farmers fertilized their crops with guano gathered from nearby islands, dramatically boosting yields in the desert landscape. The resulting agricultural surplus fueled trade, population...
Antarctica has a strange gravity hole and scientists finally know why
Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity hole” to slow, deep movements of rock inside Earth that unfolded over tens of millions of years. Using earthquake data...
Scientists discover tiny ocean fungus that kills toxic algae
Scientists have discovered a newly identified marine fungus that can infect and kill toxic algae responsible for harmful blooms. The microscopic parasite, named Algophthora mediterranea, attacks algae such as Ostreopsis cf. ovata, which produces toxins that can irritate the lungs, skin, and eyes of people exposed during coastal blooms. Remarkably,...
Koalas survived a devastating population crash and their DNA is bouncing back
Koalas suffered a massive population decline that left them with dangerously low genetic diversity. However, new genomic research suggests their rapid rebound may be helping reverse some of that genetic damage. As koala numbers rise, recombination is mixing their remaining DNA into new combinations, which can rebuild functional diversity. The...
Study Reveals Climatic Fingerprints of Wildfires and Volcanic Eruptions
Volcanoes and wildfires can inject millions of tons of gases and aerosol particles into the air, affecting temperatures on a global scale.
