I'm going to London! And I'm leading a team of YouTubers. For the next few weeks we will all be doing videos themed around the Olympics so I'm tackling the science of sport and science in and around London.

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.

Pioneering NASA mathematician Katherine Johnson has died at the age of 101. Johnson was part of a group of African-American women who worked on critical mathematical calculations in the early days of human spaceflight, as chronicled in the best-selling book and hit movie “Hidden Figures.”

"She was an American hero and her pioneering legacy will never be forgotten,” said NASA Administrator Jim Bridenstine.

Expedition 61 Crew, Record-Setting Astronaut Christina Koch Return to Earth

Expedition 61 Commander Luca Parmitano of ESA (European Space Agency), Soyuz commander Alexander Skvortsov of Roscosmos and NASA Flight Engineer Christina Koch landed safely on Earth near the town of Dzhezkazgan, Kazakhstan, Feb. 6 after bidding farewell to their colleagues on the complex and undocking their Soyuz MS-13 spacecraft from the Poisk Module on the International Space Station. Koch completed a 328-day, 139-million mile mission on the orbital outpost --- the longest spaceflight ever conducted by a woman in history and the second longest single spaceflight by a U.S. astronaut. Parmitano and Skvortsov wrapped up a 201-day mission in space spanning 85.2 million miles.

Lanzar en órbita a astronautas estadounidenses desde EE.UU, enviar un nuevo rover a Marte y continuar preparándose para misiones humanas a la Luna son solo algunos de los planes de la NASA para el año 2020.

NASA is preparing to send a chimpanzee, Ham, into space to test the effects of space on a living creature. He’s received a training regiment to prepare him for the mission ahead.

From the Series: Apollo's Moon Shot: Rocket Fever http://bit.ly/2MHAm4y

This year, NASA is building momentum across the agency and across every mission. This is a year of action. With each milestone, NASA is preparing to go farther than ever before.
NASA is going to the Moon and on to Mars, in a measured, sustainable way. Working with U.S. companies and international partners, NASA will push the boundaries of human exploration forward to the Moon. NASA is working to establish a permanent human presence on the Moon within the next decade to uncover new scientific discoveries and lay the foundation for private companies to build a lunar economy. We inspire generations and change the course of history as we realize the next great scientific, economic and technical achievements in space.

While Apollo placed the first steps on the Moon, Artemis opens the door for humanity to sustainably work and live on another world for the first time. Using the lunar surface as a proving ground for living on Mars, this next chapter in exploration will forever establish our presence in the stars. ✨

We are returning to the Moon – to stay – and this is how we are going!

Actress Kelly Marie Tran of “Star Wars: The Rise of Skywalker” lent her voice to this project.

In the next eight minutes, you’ll experience a twenty-five-and-a-half-day mission from roll-out to recovery of the first integrated flight test of NASA’s Orion spacecraft and the Space Launch System rocket, launching from the agency’s Kennedy Space Center in Florida. This uncrewed mission will be the first in a planned series of exploration missions beyond the moon, signaling what astronauts who dare to operate in deep space will experience on future flights.

Aboard the International Space Station, Expedition 62 Flight Engineer Jessica Meir of NASA discussed the revolutionary Zero-G oven recently used on the orbital outpost during an in-flight question and answer session Feb. 19 with students from the East Middle School in Grand Blanc, Michigan. The oven was launched on a Northrop Grumman Cygnus cargo ship last November, and, along with cookies baked in the oven, was returned to Earth in January on a SpaceX/Dragon resupply vehicle.

Three space travelers including record-setting astronaut Christina Koch return home from the International Space Station.

Christina Koch wrapped up a 328-day extended mission on her first spaceflight, having spent more time in space on a single mission than any other woman. Koch, along with station Commander Luca Parmitano of ESA (European Space Agency), and Soyuz commander Alexander Skvortsov of the Russian space agency Roscosmos departed the station in a Soyuz spacecraft that made a parachute-assisted landing at 4:12 a.m. EST southeast of Dzhezkazgan, Kazakhstan.

Koch's extended mission will provide researchers the opportunity to observe effects of long-duration spaceflight on a woman, as we prepare for Artemis missions to the Moon and human exploration of Mars.

NASA's Parker Solar Probe mission has returned unprecedented data from near the Sun, culminating in new discoveries published on Dec. 4, 2019, in the journal Nature. Among the findings are new understandings of how the Sun's constant outflow of material, the solar wind, behaves. Seen near Earth -- where it can interact with our planet's natural magnetic field and cause space weather effects that interfere with technology -- the solar wind appears to be a relatively uniform flow of plasma. But Parker Solar Probe's observations reveal a complicated, active system not seen from Earth.

Tune in as Boeing's uncrewed Starliner spacecraft lands at White Sands, New Mexico. Landing is scheduled at 7:57 a.m. EST on Sunday, Dec. 22. After its launch on Dec. 20, the Starliner did not reach the planned orbit and will not dock to the International Space Station. Teams worked quickly to ensure the spacecraft was in a stable orbit and preserved enough fuel for a landing opportunity.

On Monday, Jan. 20 starting at 6:50 a.m. EST, NASA astronauts Jessica Meir and Christina Koch will step outside of the International Space Station into the vacuum of space together. The duo will wrap up the work of installing new lithium-ion batteries to upgrade the orbiting lab’s power systems. The spacewalk is scheduled to last about six-and-a-half hours.

What's different about food in space? Former NASA astronaut Mike Massimino breaks down all the differences between eating on Earth and eating in space. Is astronaut ice cream REALLY a thing? Who decides what food is brought to space? Can you eat burgers in space? Why do astronauts use tortillas instead of bread?

Mike Massimino is a former NASA astronaut, senior advisor for space programs at the Intrepid Museum, and professor at Columbia University.
