Which came first, the chicken or the egg? This question has puzzled scientists and curious citizens alike for many years.

Phytoplankton blooms that form the base of the marine food web are expanding northward into ice-free waters where they have never been seen before, according to new research.

With bee pollinators in decline and pesky crop pests lowering yields, sustainable and organic farmers need environmentally friendly solutions.

Shelled marine creatures living in increasingly acidified oceans face a fight for survival as the impacts of climate change spread, a new study suggests.

Prairies from California to Washington state are catching the heat not just from wildfires but also from warming temperatures. For ranchers, it all means stress on pastureland.

In a quest to develop conservation strategies to protect a threatened species whose population has declined 80 per cent in the last 50 years, scientists at the University of Alberta have discovered the enigmatic nighthawk travels 20,000 kilometres each year in its annual migration from north of Fort McMurray to the Amazon rainforest in Brazil.

Rockweed is sometimes called an “ecosystem engineer,” because its branched structure alters the surrounding environment, and creates space for other species to find shelter and food.

A Washington State University researcher has completed the most thorough analysis yet of The Great Drought — the most devastating known drought of the past 800 years — and how it led to the Global Famine, an unprecedented disaster that took 50 million lives.

Spring in America’s heartland is often wet. That makes its soil too soft for planting. One solution to that issue is tile drainage. Growers insert a series of pipes (drain tiles) under their fields, which drains water from the soil into nearby streams and lakes. 

Why share food with non-family members when there is no immediate gain? An international team of researchers from the Max Planck Institute for Evolutionary Anthropology (MPI-EVA) in Leipzig, Germany, conducted observations of natural food sharing behavior of the chimpanzees of the Taï National Park, Ivory Coast. They found that chimpanzees who possess large, desirable food items, like meat, honey or large fruit share food with their friends, and that neither high dominance status nor harassment by beggars influenced possessors’ decisions to share.
