A new look at conditions after a Manhattan-sized asteroid slammed into a region of Mexico in the dinosaur days indicates the event could have triggered a global firestorm that would have burned every twig, bush and tree on Earth and led to the extinction of 80 percent of all Earth’s species, says a new University of Colorado Boulder study.
University of Colorado Boulder astronomers targeting one of the brightest quasars glowing in the universe some 11 billion years ago say “sideline quasars” likely teamed up with it to heat abundant helium gas billions of years ago, preventing small galaxy formation.
A team led by the University of Colorado Boulder looking for clues about why Earth did not warm as much as scientists expected between 2000 and 2010 now thinks the culprits are hiding in plain sight -- dozens of volcanoes spewing sulfur dioxide.
With the flip of a switch, a pair of instruments designed and built by the University of Colorado Boulder and flying onboard twin NASA space probes have forced the revision of a 50-year-old theory about the structure of the radiation belts that wrap around the Earth just a few thousand miles above our heads.
Creeping climate change in the Southwest appears to be having a negative effect on pinyon pine reproduction, a finding with implications for wildlife species sharing the same woodland ecosystems, says a University of Colorado Boulder-led study.
Two CU-Boulder environmental researchers -- Kevin J. Krizek and Maxwell Boykoff -- have been named Leopold Leadership Fellows for 2013 in recognition of their outstanding leadership abilities and desire to communicate scientific issues beyond academic audiences.
Researchers from the University of Colorado Boulder have been on a frog hunt.
They’ve spent three years scouring hundreds of California ponds in search of amphibians with mangled, grotesque deformities. Sometimes, the frogs have misshapen legs. Sometimes, they have extra sets of legs sprouting where they don’t belong. And sometimes, they have no legs at all.
By cataloging the deformed frogs — and the toads, newts and salamanders that share their homes — the researchers have made an important discovery: more diversity equals fewer deformations.
We’ve all heard examples of animal altruism: Dogs caring for orphaned kittens, chimps sharing food or dolphins nudging injured mates to the surface. Now, a study led by the University of Colorado Boulder suggests some plants are altruistic too.
A new study by an international team of scientists analyzing ice cores from the Greenland ice sheet going back in time more than 100,000 years indicates the last interglacial period may be a good analog for where the planet is headed in terms of increasing greenhouse gases and rising temperatures.
