From sharks to giraffes, many of Earth’s biggest and most magnificent species are threatened with extinction. A new study of the fossil record indicates that once large vertebrates disappear, evolution cannot quickly restore them — for tens of millions of years, most animals remain small.

The study, published Thursday in Science, emerged from research carried out by Lauren Sallan, a paleontologist at the University of Pennsylvania.

Studying fish that lived during the Mississippian Period, from 359 million to 323 million years ago, she noticed that they were substantially smaller than their ancestors.

Inside the drive to collect DNA from 1 million veterans and revolutionize medicine

“This is our brand new freezer,” Don Humphries said. “It holds 4 million vials.”

You’d think a freezer big enough to hold 4 million vials of blood would be easy to spot. But to my great embarrassment, I couldn’t see it.

Humphries and I were standing in a lab in the basement of the Veterans Affairs hospital in the Jamaica Plain neighborhood of Boston. He had led me through a labyrinth of windowless rooms, packed with robots handling tubes of blood donated from veterans, pipes roaring with coolant, and gorilla-sized tanks of liquid nitrogen, until he stopped next to a featureless wall.

If you enter Health Nucleus, a new facility in San Diego cofounded by J. Craig Venter, one of the world’s best-known living scientists, you will get a telling glimpse into the state of medical science in 2015.

Your entire genome will be sequenced with extraordinary resolution and accuracy. Your body will be scanned in fine, three-dimensional detail. Thousands of compounds in your blood will be measured. Even the microbes that live inside you will be surveyed. You will get a custom-made iPad app to navigate data about yourself. Also, your wallet will be at least $25,000 lighter.

More Than Half of Entire Species of Saigas Gone in Mysterious Die-Off

A mysterious die-off of endangered antelopes last spring in Central Asia was even more extensive than originally thought, killing more than half of the entire species in less than a month, scientists have found.

“I’ve worked in wildlife disease all my life, and I thought I’d seen some pretty grim things,” Richard A. Kock, of the Royal Veterinary College in London, said in a telephone interview. “But this takes the biscuit.”

At a scientific meeting last week in Tashkent, Uzbekistan, Dr. Kock and his colleagues reported that they had narrowed down the possible culprits.
