Plant biologist Karl Hasenstein on growing radishes in space: GotG13

Yesterday I read that Trump adviser Myron Ebell, a climate change denier, thinks that the green movement is the greatest threat to freedom.

There can’t be a more iconic symbol of Halloween than a witch riding a broomstick. In olden times it wouldn’t have been a problem to wander out into the woodland and cut a stout pole and then find sticks to make the sweeping end, and then you’d have yourself a fine broom, or besom. I suspect most of them were used for more mundane purposes – they are jolly useful things to have to hand.

I’m not a chemist, but I do find plant chemistry (and the links and patterns between different plants) to be a fascinating topic. Fortunately there are chemists out there who can bring these to our attention, and Compound Interest includes some great plant-related infographics amongst a wider spread of chemical topics.

While we’re waiting for Tim Peake to blast off to the International Space Station (ISS) to begin his Principia mission, I thought it might be fun to have a look at the first Briton in space – Helen Sharman, who was also the first woman to visit the Mir space station, in 1991.

One of the nerdy things I enjoy doing in my spare time is researching the first seeds to have made it into space. This is what I have found so far:

From the moment humans started to reach for the skies, we have used other species from Earth to test what’s safe and what happens to life away from its natural habitat on the planet’s surface.

In this episode, Emma recaps important spacecraft Arrivals and Departures and learns about growing nutrients and medicines in space. There’s a new plant experiment running on the International Space Station, and exciting news from ESA.

COP21, the United Nations conference on climate change, has ended with a ‘landmark’ agreement that climate change is something we all need to tackle together. Last week I was talking about what gardeners can do to reduce their carbon footprint, and a lot of it is about being thrifty with resources – something that tends to come naturally to us! Over the weekend, Ryan has done his bit by recycling plastic plant pots in my direction. He came across a newly landscaped commercial building, where the unwanted plant pots were being discarded.

I imagine the Apollo 11 astronauts had plenty to do while they were hurtling towards the Moon, but from a bystander’s perspective it was probably pretty dull stuff. Still, it’s Day 3 of the mission, so let’s have a look at what they’ve got stashed away in their space age picnic basket.

At the beginning of the year, I set up a new mission in the AeroGarden, growing two peppers (Popti and Redskin) and a tomato (Veranda Red). Ten days later, I had two tomato seedlings, which I had to thin to one. The peppers were a bit slower, but by 19th January they had germinated (and been thinned) too.
