The number of dairy cows is now higher than ever.

At the northern edge of the state, Weld and Larimer counties are already home to high numbers of beef and dairy cattle, buttressed by the region's numerous feedlots, which send the animals to several nearby slaughterhouses. But an expansion of a cheese factory owned by dairy giant Leprino Foods will require even more cows.

Let's say a pregnant woman develops high blood pressure.

In ordinary circumstances, her medical team will monitor her condition. If there's a threat to the fetus, the doctor might want to bring on labor early. In the end, mother and baby are usually fine.

Donald Trump is the apparent GOP presidential nominee after his two remaining rivals ended their White House bids.

Scientists have been able to make and study human embryos in their labs for decades. But they have never been able to keep them alive outside a woman's womb for more than about a week.

That limitation meant scientists were unable to conduct a range of detailed research into early human development.

But now researchers say they have discovered a way to keep human embryos alive in the laboratory about a week longer than ever before, and through a critical period of development.
