In a new study, a team of geologists and biologists led by CU Boulder resurrected ancient microbes that had been trapped in ice—in some cases for around 40,000 years.
New fossil research shows how human impacts, particularly through the rise of agriculture and livestock, have disrupted natural mammal communities as profoundly as the Ice Age extinctions.
North America's mammoth species were breeding together within the past 40,000 years. Fossil teeth found in Canada show that Columbian and wooly mammoths regularly had calves together where the different species mixed.
As the weather starts to warm across the country, throngs of people will take to the great outdoors to bask in the sun, crack open a cold one and, inevitably, fire up the grill.
