The other day, my friend and I were musing over the fact that many flowering plants require a third party pollinator in order to complete the fairly simple act of reproducing. And that while this sexual ‘three-or-moresome’ has some pretty great advantages, it also forces plants to spend a fair amount of energy just in attracting the middle men.… Read more
Winter time can be hard for plants, and many species that live in particularly cold climates do their best to ‘opt out’. When autumn comes, leaf shedding deciduous species effectively shut it all down. They reabsorb as many nutrients as they can from their leaves, throw the remaining orange-red husks to the ground, and hunker down for the cold times.… Read more
Last weekend, the Fast Forward Science competition held its Super Fast challenge – 24 hours to tell a story about science on Instagram… this year, with the topic of “Hero”. I didn’t have to look far in my neighbourhood to find a true hero of the plant world: dandelion.… Read more

You’ll probably remember this one from grade school biology. Mitochondria are ‘the powerhouse of the cell’. Which basically means that mitochondria take sugars and break them down to make energy.
But those little powerhouses were once so much more- they were an entire organisms. A very long time ago, a certain type of proteobacteria was engulfed by a single celled host organism, but that organism decided that instead of digesting the proteobacteria, it would hold onto it. With time, the proteobacteria evolved into the modern mitochondria, a process that involved most of its very own bacterial genome being stolen away, and sequestered in the nucleus of the host.… Read more
Hello to our English-speaking readers. This post is in German, you can find an English version here.
Hallo alle zusammen, heute gibt es mal etwas anderes.
Letztes Wochenende waren Joram und ich beim Potsdamer Tag der Wissenschaften, um Plants and Pipettes vorzustellen. Während wir normalerweise hier auf Englisch schreiben und sprechen, haben wir uns dieses mal auf Deutsch unterhalten, was mich ein kleines bisschen gestresst hat (Abb. 1). Dennoch hatten wir viel Spaß dabei, mit dem Publikum zu reden, Sonnenblumensamen zu verteilen und Fragen einzusammeln.… Read more
Hi all. Something a bit different today.
On the weekend, Joram and I went to Communicate Plant Science at the Potsdam Day of Science. Although the communication was in German, which gave me a bit of stress (Figure 1), we managed to have a nice time chatting to the public, giving away some sunflower seeds, and asking them to ask us questions!… Read more
If you’re in the Potsdam/Berlin area this Saturday, May 11th, you’re in for a treat! You can meet the heads behind Plants and Pipettes (That’s us!) at the Potsdam Day of Science.
Eine deutsche Version des Artikels gibt es hier.
Come and say hi, bring your favourite questions about plant science and follow the hashtag #ptdw.… Read more
The synthetic poison 1080 (pronounced ten eighty), is used widely in Australia and New Zealand to control the population of feral animals that threaten local species with extinction. While 1080 is fatal to feral fauna, the scientific magic of it, is that many native species can snack on the substance without any harm. All because of some peas, their poison, and a plant v. herbivore arms race.… Read more
