They are. And I think this is just a really cool example of the resilience of some animals. And it also really shows how these events that can seem so improbable actually probably happen quite often over the span of evolutionary time. And they really shape the biological world around us.

When humans hold their breath, the urge to breathe is driven by a buildup of carbon dioxide in our blood, not oxygen. That's the case for virtually all other mammals, but not for gray seals, according to a study published today in the journal Science.

Researchers varied the amount of oxygen and carbon dioxide captive gray seals could breathe and then watched how long they stayed underwater to find food. The higher the oxygen levels, the longer seals stayed under. But carbon dioxide levels had little effect, suggesting seals evolved a new way of not drowning. Jonathan Lambert, NPR News.

How iguanas got to Fiji from the Americas has long been a mystery. The lizards could have walked over many generations across ancient land bridges, or they could have floated there on a raft of tangled vegetation. New genetic analyses published in the journal PNAS point to the raft idea.

The study says Fijian iguanas are likely too young, evolutionarily speaking, to have crossed the ancient land bridges. And that suggests that these lizards floated around 5,000 miles to reach the island. Jonathan Lambert, NPR News.

So the NIH was one of the federal health agencies that was hit by this communications blackout. You know, queries from reporters were met with silence. All travel was suddenly canceled. So a general sense of fear, confusion, and anxiety settled over the labs and offices and clinics on the sprawling NIH campus just outside Washington. And, you know, that was just the beginning.

Well, then a real shocker hit late on a Friday. It was February 7th. The NIH announced that the agency was capping what the NIH pays universities, medical schools, research hospitals, and other institutions for so-called indirect costs at 15%.
