After so many smoke-filled summers and record-setting burns, residents of Western North America are no strangers to wildfires. Still, many questions are circulating about why forest fires are becoming larger and more severe – and what can be done about it.   Is climate change fueling these fires? Does the long history of fighting every

Birds’ nests are snug little places: safe, warm, and lined with soft materials to keep the vulnerable babies comfortable and protected. For the tufted titmouse (Baeolophus bicolor) and its closest relatives, that material is often the fur of mammalian carnivores, which scientists had thought pillaged from dead animals, or opportunistically snagged when the animals shed.

Abrupt disruptions to Earth’s climate thousands of years ago that caused extreme sea-level rise and mass ice cap melting can serve as an early warning system for today’s planetary tipping points, according to new research.    Climate tipping points – which are irrevocable over centuries or longer – are thresholds past which large and rapid

Paleontologists have uncovered an enormous fossil graveyard of squiggly, alien-like Jurassic sea creatures beneath a limestone quarry in the UK’s Cotswolds region. The fossil find includes perhaps tens of thousands of marine invertebrates called echinoderms – meaning “hedgehog skin” in Greek, and including the ancient ancestors of modern starfish, sea cucumbers, sea urchins and frilly-limbed sea

Pure water is an almost perfect insulator. Yes, water found in nature conducts electricity – but that’s because of the impurities therein, which dissolve into free ions that allow an electric current to flow. Pure water only becomes “metallic” – electronically conductive – at extremely high pressures, beyond our current abilities to produce in a

Scientists on Thursday unveiled the most exhaustive database yet of the proteins that form the building blocks of life, in a breakthrough observers said would “fundamentally change biological research”.   Every cell in every living organism is triggered to perform its function by proteins that deliver constant instructions to maintain health and ward off infection.
