Citrus greening is a disease that turns oranges sour and half-green, and it’s been ravaging orange groves in Florida for years. A novel strategy for controlling its spread may be found by mimicking the mating call of a tiny aphid-like brown insect called the Asian citrus psyllid.
Unplggd offers a great little how-to for anyone hates mosquitoes (read: everyone) and is sick of buying new candles and cans of spray. All you need is some orange peel and a spent plug-in repellent you might have lying around.
It’s no secret that the energy stored in citrus fruits can generate an electrical current (a favourite demonstration of school science teachers). But what happens when you use 2500 oranges? You can power a neon billboard, apparently.
