On Monday, the USDA brought us some much needed good news, when it reported data suggesting that honeybees might finally be bouncing back from colony collapse disorder. Today, a team of scientists countered with some seriously bummer pollinator news. A new study published in the journal Nature indicates that artificial light pollution might be a much bigger problem for pollinators — and their plants — than we realised.

In nature, blue is much rarer than you might think. Sure, the sky is blue when the weather's nice, and so is the ocean. But the vast majority of plants and animals are incapable of making blue pigment. Brilliantly-coloured peacocks appear blue not because their feathers are coloured that way, but because of how they reflect light. Less than 10 per cent of the world's 280,000 flowering plants produce blue flowers, which may be why they're often a symbol of the unattainable in folklore and literature.

Designing simpler spacecraft is what helped us finally put rovers on Mars and start exploring the Red Planet. Embracing simplicity might also give us simple, inexpensive robots that thrive doing very specific tasks, instead of multi-million dollar humanoids that have trouble just staying on their feet.

In the caterpillar-versus-plant fight, the winner might seem obvious. One side sits motionless in the sun, while the other feasts on it. But the tomato plant has a nefarious defence strategy. In some encounters with herbivores, it winds up relatively unscathed, while the caterpillars wind up eating each other.

It's one of the biggest mysteries in this global experiment we're conducting by pouring 10 billion tonnes of carbon into the atmosphere each year: What will happen to the plants? Will the relentless burning of fossil fuels prompt our leafy green friends to suck down more CO2, tapping the brakes on climate change? Or are the trees unable to bail Earth's atmosphere out this mess?

In the TV series, Star Trek: Voyager, the space ship was the first of its kind to be built with biological circuitry designed to speed up its processing capabilities. What once was science fiction, however, creeps closer to reality as researchers have successfully created a cyborg rose that functions as an electronic circuit.

When farmers spray their crops with pesticides and other treatments to help ensure their survival, 98 per cent of those chemicals bounce right off the plants and end up in the groundwater as pollution. It's a waste, and harmful to the environment, so researchers at MIT came up with a cheap but effective way to instead make those chemicals stick to crops.

Sunflowers may look like the sun if you squint your eyes a bit, but they also do this weird thing where they turn to face the sun, hence the name. But how and why these plants move over the course of a day has stumped scientists for over a century.

Video: Meet the Drosera Capensis, also known as the Cape sundew. It's a deadly little thing that looks like some sort of alien finger trap, but it's actually a carnivorous plant with sticky tentacles that basically entomb bugs that come across its way. It's incredible to see how it traps the bug as if it were hugging it to paralyse it, and then folding vertically to trap it forever.
