Greenhouses are an integral part of U.S. agriculture. Nearly $200 million of food is produced in domestic greenhouses each year, and the facilities play a vital role in producing seeds and transplantable vegetation. Understanding how to keep greenhouse plants healthy can translate to increased revenue for producers.

A recent study of an ancient growing medium has implications for advancing growth and yield of greenhouse crops grown in soilless conditions.

Planetary scientists on both sides of the Atlantic have tracked down a rare molecule in the atmospheres of both Mars and Venus. The molecule, an exotic form of carbon dioxide, could affect the way the greenhouse mechanism works on Venus.
