Unsafe levels of radiation found in Chernobyl crops

Crops grown near the Chernobyl nuclear site in Ukraine are still contaminated with radiation from the explosive 1986 disaster.  In a new study, researchers found that wheat, rye, oats and barley grown in this area contained two radioactive isotopes — strontium 90 and cesium 137 — that were above safe consumption limits. Radioactive isotopes are […]

Bonobos, much like humans, show commitment to completing a joint task

During this time, mature males produce an elaborate acoustic display known as “song,” which becomes the dominant source of ambient underwater sound between December and April. Following reports of unusually low whale numbers that began […]

Wildfires May Exacerbate Asthma in the Western United States
