Scientists have long known that seeds gobbled by birds and dispersed across the landscape tend to fare better than those that fall near parent plants where seed-hungry predators and pathogens are more concentrated.

Since the discovery of the Van Allen radiation belts in in the Earth's upper atmosphere in 1958, space scientists have believed that these belts consisted of two doughnut-shaped rings of highly charged particles — an inner ring of high-energy electrons and energetic positive ions, and an outer ring of high-energy electrons.

 A new study shows that internal rhythm of harvested vegetables such as cabbage can be altered by changing light-dark cycles. In this new report, the scientists showed how manipulation of circadian rhythms caused cabbage to produce more phytochemicals, including antioxidants. The findings suggest that storing fruits and vegetables in dark trucks, boxes and refrigerators may reduce their ability to keep daily rhythms.

About 40,000 years ago Europe suffered a major volcanic eruption in the Phlegrean Fields west of Naples. Deposits known as "Campanian Ignimbrite" are still present in the region and bear witness to the event. The ash that was flung into the upper atmosphere from the CI eruption was distributed far across Eastern Europe.

Our internal circadian clock regulates daily life processes and is synchronized by external cues, the so-called Zeitgebers. The main cue is the light-dark cycle, whose strength is largely reduced in extreme habitats such as in the Arctic during the polar summer. Using a radiotelemetry system a team of researchers from the Max Planck Institute for Ornithology have now found, in four bird species in Alaska, different daily activity patterns ranging from strictly rhythmic to completely arrhythmic.

An international team of scientists has developed crop models to better forecast food production to feed a growing population – projected to reach 9 billion by mid-century – in the face of climate change.
