Mysterious hybrid species discovered hiding among 144-year-old 'zombie seeds' from secretive experiment
Scientists participating in one of the longest-running active scientific experiments have discovered a surprising hybrid plant hiding among seeds buried at a secret location on a university campus since 1829.
Why do leaves change color in the fall?
Plants draw on a suite of pigments to produce energy from sunlight, and in the fall, some become more obvious than others.
Asteroid that wiped out the dinosaurs allowed flowers to thrive in a post-apocalyptic world
Scientists have discovered flowering plants were largely unscathed by the Cretaceous-Paleogene (K-Pg) mass extinction event 66 million years ago, allowing them to take advantage of the new, dinosaur-free planet.
Mystery of 'living fossil' tree frozen in time for 66 million years finally solved
The Wollemi pine was thought to have gone extinct 2 million years ago until it was rediscovered by a group of hikers in 1994. Now, scientists have decoded its genome to understand how it's survived — almost unchanged — since the time of the dinosaurs.
'Once again, innovation and proliferation ended with catastrophe': The environmental disaster of plants taking over the world
The evolutionary leap that allowed plants to live on land 400 million years ago upended Earth in a way unseen since the Great Oxidation Event over 1.5 billion years earlier.
Mysterious bamboo regeneration baffles scientists ahead of once-in-a-century blooming event
Henon bamboo flowers only once every 120 years then vanishes for years, and researchers have no idea how it regenerates.
Genetically engineered pink pineapples are flying off shelves: What gives them their distinctive color?
The food giant Del Monte has created a genetically engineered pink pineapple that owes its rosy hue to higher concentrations of a pigment called lycopene.
Tropical rainforests could get too hot for photosynthesis and die if climate crisis continues, scientists warn
Data collected by the International Space Station has revealed a small fraction of leaves in the world's tropical rainforests are already exceeding peak temperatures, and scientists warn that this could increase.
