For many people, the beauty of spring is countered by the sneezing, runny nose and itchy eyes of allergies that come with warmer weather. For those people, science has some bad news – climate change may be making pollen season longer and more severe.

Scientists at the Salk Institute hope to tackle climate change and food security by unraveling the genomic architecture behind various plant species, and have gleaned some valuable new lessons from the fastest-growing example we know of.

Everyone already knows that compost made from food scraps helps plants to grow. Now, however, scientists have fermented food waste to create a liquid fertilizer that boosts the number of beneficial bacteria within the plants themselves, and in their soil.

As a seedling matures into a tree, its trunk and branches become stiffer and stronger. Scientists have now replicated this effect in a photosynthesis-assisted 3D-printing ink, made partially from spinach.
-
While pest insects can have a devastating effect on crops, pesticides can likewise cause a great deal of damage to the environment. That's where CropCoat comes in, as it's designed not to kill harmful insects, but to "hide" plants from them instead.

A novel analytical technique has revealed undiscovered compounds in an ancient Maya drug container previously thought to only be used for tobacco. The findings offer the first clear evidence that the Maya mixed tobacco with other plant materials.

As anyone who has grown climbing plants will know, the things are great at grasping onto thin objects such as strings or bamboo poles. A new robotic gripper, inspired by such plants, could find use in the handling of small, delicate items.
-
Pesticides may indeed kill plant pathogens, but they're also harmful to the environment. Newly developed nanoparticles may provide a more eco-friendly alternative, as they boost the immune systems of crop plants, then harmlessly dissolve.
-
If crop plants aren't receiving enough nutrients, they'll typically have lower-than-normal nitrogen levels. A portable new device could allow farmers to check those levels on the spot, so they can start addressing the problem as soon as possible.

Scientists have genetically modified a tomato to produce L-DOPA, a drug used to treat Parkinson’s disease. The researchers say the innovation could be an easier way to produce the medicine in regions where access to the synthesized drug is restricted.

Some people, and I count myself among them, are so scatterbrained and disorganized that they should never be put in charge of another living being. If that's you, then welcome to the future! Come get your six-hundred-dollar automated pot plant.

Fertilizers typically contain phosphorous, as it's essential to growing plants. Unfortunately, though, it can become "locked" in the soil, and thus not available to crops. That said, it turns out that the addition of a microbe could unlock it.
