3D printed corals grow algae that photosynthesize more efficiently

Central to coral reefs around the world is the deeply interdependent relationship between corals and algae. This interconnection is responsible for algae’s protected habitat, corals’ bright colors, and the mutual exchange of nutrients for photosynthesis. Algae growth is modulated by a process called self-shading, decreasing exposure to light. In an artificial setup, however, this process prevents researchers from growing coral quickly. To prevent this light … Continue reading 3D printed corals grow algae that photosynthesize more efficiently

Ice Cores and Roman Lore: Modern climate science helps scientists and historians piece together the past

by Lorena Lyon figures by Rebecca Senft Today, the discussion of climate change generally relates to human impact on the environment since the Industrial Revolution (1760 to mid-1800s). But, how have humans been impacting the planet before then? And how can we find out? It turns out a type of climate science using something called ice cores can give us detailed information on how past … Continue reading Ice Cores and Roman Lore: Modern climate science helps scientists and historians piece together the past

Listen Closely: Coral reefs are losing their sound

by Samantha Tracy figures by Sean Wilson A solo diver dips under the surface of crashing waves to reveal a plethora of attention-grabbing colors in astounding brightness. The image of a coral reef is exciting and overwhelming for the human brain, but another world comes to life when we close our eyes. A cascading orchestra of gentle bubbling, a faint crackling chorus of snapping shrimp, … Continue reading Listen Closely: Coral reefs are losing their sound

Global warming threatens most of the world’s wheat production, and the Paris Agreement cannot prevent it

Study predicts that global warming will affect 60% of the world’s wheat-growing areas by 2100, even if the Paris Agreement’s targets are met. Damage would be global but developing countries and low-income regions likely to suffer most as rising temperatures affect global food production.
