A Costa Rican flower has turned this foe into friend, according to a new study. One species of the so-called arum plant has evolved to attract a species of plant bug instead of a typical beetle pollinator, helping them spread their pollen far and wide.

For millennia, humans have been chopping wood and harvesting plants, and how we've grown and extracted materials from the earth remains largely unchanged. A group of MIT researchers hopes to cut back on inefficiencies such as transportation and milling by growing wood-like plant tissue in the lab.

A key method for removing carbon dioxide from the atmosphere, reforestation is increasingly touted in plans to tackle climate change. But a study finds that tree nurseries in the U.S. will need to rapidly accelerate their production of seedlings to more than double the current rate in order to meet target climate goals.

Research indicates that seaweed could be a powerful tool in reducing greenhouse gases emitted by livestock. Adding a small amount of a particular species of seaweed called asparagopsis to a cow's diet can decrease the amount of methane produced by 98 percent.
