<p><strong>The genome of a sea cucumber, collected at a depth of 2400 m during a submarine trip to a hydrothermal vent, sheds light on&nbsp;genetic features that help marine animals to survive in extreme conditions.&nbsp;</strong>Hydrothermal vents&nbsp;are an unlikely environment for animals to flourish, characterized by rapid changes in temperature and a challenging chemistry: acidic pH, rich in sulfur and methane. Not to mention the high hydrostatic pressure and the darkness of the deep sea. A team of scientists at the Sanya Institute of Deep-sea Science and En...

Oat is among the top ten cereal crop species in terms of global production. It can adapt to different climates, and farmers can grow it successfully even in harsh environments where other crops such as rice and corn fail. However, not all oat plants are the same. Based on their grains, two major oak varieties can easily be distinguished: hulled, grains that are covered in a non-edible husk, and naked, grains that have a soft outer casing that easily separates from the edible grain during threshing.
