As part of Doug Emlen’s biology lab at the University of Montana in Missoula, Jillian del Sol was no stranger to bug battles. Year after year, study after study, species after species, students in Emlen’s lab have revealed the dramatic effects of sexual selection on male biological weaponry. So when she travel to East Asia to witness the tree trunk battles of the rhino beetles as part of her Ph.D. research, she came prepared to document the ecological conditions that influence chitinous combat. To her surprise, the successful male beetles didn’t just claim their prize after ousting their foes. Instead, they began to sing- or rather chirp and chitter at the females. This acoustic courtship continued even as they mated. Clearly, there was more to this mating system than just an escalating arms race between males. Now equipped with 150 beetles from field sites from Japan, del Sol aims to record these acoustic mating rituals in detail to hopefully discover why this bruiser bug suddenly turns from fighter to lover.

Tips on mushroom hunting from the president of the Mycological Society of America.

Bacteria and viruses hitch a ride inside droplets of all kinds—sneezes, raindrops, toilet splatter. By reviewing footage of different types of drops, applied mathematician Lydia Bourouiba records and measures where they disperse in order to better understand how diseases spread. Watch how Bourouiba designs tests—some inescapably humorous and awkward—to study infectious disease transmission.

By 1982, fewer than two dozen California condors lived in the wild. By 1985, only one wild breeding pair was known to exist. That's when the U.S. Fish and Wildlife service decided to capture any remaining condors and bring them to live--and breed--in captivity. The Peregrine Fund, in Boise, Id., houses the largest California condor breeding center in the U.S.--with nearly sixty California condors living on site. Bill Heinrich and Taiana Carvalho take us "behind the enclosure" for a tour of the condor compound.

Given their outlandish names and traits, imaginary companions might be dismissed as nostalgic relics of our ephemeral youth. Yet, research by psychologists has revealed that imaginary companions can provide glimpses into the development of critical creative, social, and cognitive skills of children. In the third episode of The Real Guide to Imaginary Companions, we'll see how developmental psychologist Tracy Gleason uses imaginary companions to study how children form relationships. We'll also learn how developmental psychologist Stephanie Carlson tests the role of pretend play, such as creating an imaginary companion, in a child's ability to exercise self-control.

Think oysters are good on the half shell? They may be even better whole. Oysters can restore marine habitats by cleaning water, creating homes for other sea life and preventing coastal erosion. But oyster populations around the world have declined, experts say. Find out how scientists in New York are working to replenish oyster populations in the waters around the city.

In perhaps the cutest study published in the Proceedings of the National Academy of Sciences, psychologist Marcel Zentner and Tuomas Eerola found that babies will spontaneously boogie when they hear music and other rhythmic sounds. The findings suggest babies are not great dancers, but they smile more when they do hit the beat.

An elephant shrew is neither an elephant nor a shrew and has a manatee for a close relative. It's more like a mix between a miniature antelope and anteater. Researchers recently discovered a new species of elephant-shrew in Tanzania

Ultravox - Hymn 1983

Give us this day all that you showed me -
The power and the glory
till my kingdom come.
Give us this day all that you showed me -
The power and the glory
till my kingdom come.
Give me all the storybook told me
The faith and the glory
till my kingdom comes.

And they said that in our time
all that's good will fall from grace.
Even saints would turn their face
in our time.
And they told us that in our days
Different words said in different ways
Have other meanings from he who says
in our time:

Give us this day all that you showed me -
The power and the glory
till my kingdom come.
Give me all the storybook told me
The faith and the glory
till my kingdom comes.

And they said that in our time
we would reap from their legacy
We would learn from what they had seen
in our time.
And they told us that in our days
We would know what was high on high
We would follow and not defy
in our time.

Give us this day
