The bizarre physics of fire ants

They're not just an animal, they're a material. And that's got engineers interested.

Red imported fire ants (solenopsis invicta) are native to South America and an invasive species in the United States. One of the adaptations that makes them so hardy is that they can build large structures by linking their bodies together. This is how they form rafts that can float during floods. When they're aggregated together, fire ants can be seen as a material and the Hu lab at Georgia Tech has been testing that material for years.

Why sports sound better in your living room

Why sports sound better in your living room

Audio engineers are the unsung heroes of the live sports broadcast.

We don’t often think about audio when we watch sports on TV, but it’s a huge part of the experience. We spoke with several A1 audio engineers who mix the sounds of sports to learn more about what it takes to capture the crack of the bat and the swish of the net.

From the cadence of the quarterback to the sounds of skates on ice, audio mixers are tasked with getting microphones close enough to the action to gather the sounds but still out of the way of the players and the fans.

Once the microphones are set up, they handle the stressful task of live mixing all the audio for the broadcast, so that we can hear the announcers and the sounds of the game, despite thousands of screaming fans and the PA system blaring music.

In the end, if they do the job right, you’ll forget they exist.

Why Do Venomous Animals Live In Warm Climates?

Why Do Venomous Animals Live In Warm Climates?

As a Canadian-Australian, I have always wondered why it is that Australia has so many venomous animals that can kill you while Canada has virtually none. But it's not just Australia - it seems like all beautiful, warm places are cursed with venomous native species. So I set out to find the truth: why have all these venomous species evolved in the world's best holiday destinations?

I asked chemists, visited the zoo, interviewed entomologists and snake experts. The answer I found was complicated:
1. The majority of venomous species are ectotherms, cold-blooded creatures whose internal temperatures are governed by their surroundings.
2. This means they have limited periods of activity - mainly while it's warm out, and can only exert short bursts of energy, so they are generally "sit and wait" predators. This may explain why they, more than mammals or birds, evolved venom.
3. It also explains why there are more of these species in warm climates. There are more of all species in warm climates, but this trend is especially pronounced for ectotherms.
4. So there are a greater number of venomous species in warm places, simply because there are more species in warm places. Cold climates still have venomous creatures, like the rattlesnakes of Canada and European vipers.
5. But history also has a role to play. In Australia, there were no snakes until 20 million years ago when a venomous sea snake from Asia encountered the land, sending venomous species to all corners of the continent. Later non-venomous arrivals have done well in the tropics but not as well in Australia's colder climates, so venomous types still dominate there. Hawaii has no venomous land snakes and nor does Jamaica.
6. The recent ice age also would have driven ectotherms from the northern parts of the Northern Hemisphere. This is why there are no snakes in Ireland, for example.

By breeding house cats with wild animals, humans developed hybrid cats that look like little leopards. Bengal cats are a breed that was developed by breeding domestic cats with asian leopard cats. The first American bengal breeder is a woman named Jean Mill, but her work has continued through other breeders. We met one of those breeders, Anthony Hutcherson, when we went to film the cats at the Westminster Dog Show. Besides bengals, we also saw another hybrid breed: savannahs. Instead of asian leopard cats, savannahs were developed by breeding house cats with servals. Unlike the other two breeds, the last breed we met, toygers, are not hybrid cats. Breeder Judy Sugden created the breed by carefully breeding domestic cats with qualities that resemble wild tigers. To learn more about the cats and the breeders that made possible, watch the video above.

Finding alien life on a distant planet would be amazing news - or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.
