Many images of rural America are food-related—a freshly-baked apple pie cooling on the windowsill, a roadside produce stand brimming with sweet corn and tomatoes, or a Norman Rockwell print showing a family sitting down to dinner. But the reality is that many people in rural America face hunger and don’t always know where their next meal is coming from.

The gravitational dance between two galaxies in our local neighbourhood has led to intriguing visual features in both as witnessed in this new NASA/ESA Hubble Space Telescope image. The tiny NGC 1510 and its colossal neighbour NGC 1512 are at the beginning of a lengthy merger, a crucial process in galaxy evolution. Despite its diminutive size, NGC 1510 has had a significant effect on NGC 1512’s structure and amount of star formation.

Surgeons were able to identify and remove a greater number of cancerous nodules from lung cancer patients when combining intraoperative molecular imaging (IMI) – through the use of a contrast agent that makes tumor cells glow during surgery – with preoperative positron emission tomography (PET) scans. The study from the Abramson Cancer Center at the University of Pennsylvania (ACC) is the first to show how effective the combination of IMI with the tumor-glowing agent can be when combined with traditional PET imaging. Researchers published their findings today in Annals of Surgery.

Relocating coffee areas, along with forestation and forest conservation, to higher altitudes to cope with climate change could increase Ethiopia‘s coffee farming area fourfold, a study predicts.

Biochar from recycled waste may both enhance crop growth and save health costs by helping clear the air of pollutants, according to Rice University researchers.
