Scientists and environmental activists have consistently called for drastic reductions in meat production as a way to reduce emissions and, in doing so, combat climate change. However, a new analysis concludes that a smaller reduction, borne by wealthier nations, could remove 125 billion tons of carbon dioxide -- exceeding the total number of global fossil

Researchers used genomics to investigate the genetic changes causing resistance to transgenic crops in field populations of the corn earworm, also known as cotton bollworm or Helicoverpa zea. They discovered that in this voracious pest, field-evolved resistance was not associated with any of the 20 genes previously implicated in resistance to the pest-killing proteins in

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before the appearance of the first animals. A team has observed that this species forms multicellular structures that bear striking similarities to animal embryos.

At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results provide the first direct geochemical evidence of the slushy planet -- otherwise known as the 'plume-world ocean' era -- when sky-high carbon dioxide levels forced the frozen Earth into

Romance is a complex affair in humans. There's personality, appearance, seduction, all manner of physical and social cues. Mosquitoes are much more blunt. Mating occurs for a few seconds in midair. And all it takes to woo a male is the sound of a female's wingbeats. Imagine researchers' surprise when a single change completely killed

Research helps reconstruct an ancient climate and challenges the timing of the Andes Mountains uplift. As the Earth faces unprecedented climate change, a look into the planet's deep past may provide vital insights into what may lie ahead. Knowledge of the natural world millions of years ago is fragmented, but a 15-year study of a

A study shows how scientists can control cell division on demand outside of a living system. The work is a significant leap forward that can enhance our grasp of human biology and disease. A living cell is a bustling metropolis, with countless molecules and proteins navigating crowded spaces in every direction. Cell division is a

Scientists are repurposing their research about bacteria-powered biobatteries into a new idea for artificial plants that can feed off carbon dioxide, give off oxygen and even generate a little power. On average, Americans spend about 90% of their time indoors, and the air we breathe at work, school or home affects our overall health and
