Animals & Wildlife Courses

Picture a patch of night so narrow that it spans less than one-tenth the apparent width of the full Moon. Hubble revisited that direction in Fornax for nearly two million seconds, and the resulting eXtreme Deep Field contains roughly 5,500

The Hubble eXtreme Deep Field turns an apparently empty patch of sky into thousands of faint galaxies whose light began its journey at different distances and times, in some cases more than 13 billion years ago, making the image a layered r

You stand at Parker River National Wildlife Refuge and a creek cuts the green in half. The grass looks thin, like a lawn laid over a puddle. NOAA's name for the carbon held in places like this is coastal blue carbon. Most of it is not in th

In the heat of June 1858 the Thames became unbearable in a Parliament whose windows face the river, and within weeks the Commons was debating ninety million gallons a day and a £2,500,000 scheme. Follow what Joseph Bazalgette actually built

An antlion pit is not a hole. It is a slope of dry sand held just short of collapse, and the larva at the bottom spends its life throwing back the grains that would settle it into a safer angle. A trapdoor spider does the same trick with di

Birds threw away the sweet receptor before there were birds, and none has ever got it back. Follow how hummingbirds, songbirds and woodpeckers each rebuilt the savoury receptor instead — three separate times, from the same missing part — an

The lava took 42 farms — 0.8 percent of the farms in Iceland. It was the gas that emptied the country. Eight million tonnes of fluorine settled on grass that still looked exactly like grass, and more than 60 percent of Iceland's grazing ani

A quarter of this animal is jaw muscle, and 31 percent of its touch cortex is teeth. It has never had a drink of water. It survives eighteen minutes with no oxygen at all, where a mouse dies inside a minute. Its hairs report which way they

For seventy-one minutes the USS Greeneville could hear the ship it was about to kill. Hearing was never the problem. This is the gap between a sound and a place — bearings that are only lines, an ocean that bends sound into channels and bli

Balance a dead flamingo on one leg and it stays up; balance it on two and the joints give way. That experiment, a force plate at Zoo Atlanta and years of counting birds in a zoo lagoon have produced two confident answers — and the two teams

The Moon retreats about 3.8 centimetres a year, and we know that because Apollo left mirrors on it and observatories have been firing lasers at them since 1970. But run that rate backwards and the Moon touches Earth 1.6 billion years ago —

At 12:30 on Boston's waterfront, a 50-foot tank let go. A roar like a train rolled over the North End, then 2.3 million gallons of molasses became a wave.
