Ocean creatures keep millions of viruses at bay
The rainforest has long been a cradle for virus-kind. HIV, ebola and yellow fever all started out in those lush fortresses of biodiversity. But when it comes to harboring viruses, the rainforest has nothing on the ocean. Scientists have tallied…
New ‘law’ to explain how glaciers flow over soft ground
(American Association for the Advancement of Science) Addressing a major source of uncertainty in glacier-flow models, researchers present a new slip law to describe glaciers sliding on soft, deformable material.
Fatal eruption triggered a 'volcanic freeze'
On Dec. 22, 2018, the Anak Krakatoa volcano in Indonesia erupted in a violent display of ash and lava. The event was so powerful that it caused an underwater collapse of the southwest portion of the volcano, reducing its height…
On Mars or Earth, biohybrid can turn carbon dioxide into new products
Chemists have created a hybrid system of bacteria and nanowires that captures energy from sunlight and transfers it to the bacteria to turn carbon dioxide and water into organic molecules and oxygen. On Earth, such a biohybrid could remove carbon dioxide from the atmosphere. On Mars, it would provide colonists with raw material to manufacture organic compounds ranging from fuels to drugs. The efficiency is greater than the photosynthetic efficiency of most plants.
Vodka From Thin Air: An Unusual Climate Prize Hits a Coronavirus Snag – News18
In 2017, Stafford Sheehan handed a friend an unusual bottle of booze. He had made it himself — but not the usual way. A chemical physicist, Sheehan had invented a process to make alcohol from carbon dioxide, the greenhouse gas…

Why did Ecuador's largest waterfall disappear?
Earlier this year, the 500-foot-tall San Rafael waterfall in the Ecuadorian Amazon seemed to vanish. The country’s largest waterfall in both height and volume, its disappearance wasn’t caused by a sudden drop in water levels, but instead because the Coca…
Causes of global warming: How scientists know that humans are responsible – Yale Climate Connections

How stable is deep ocean circulation in warmer climate?
If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe – a scenario that has occurred during past cold glacial periods. Now, a new study suggests that short-term disruptions of deep ocean circulation occurred during warm interglacial periods in the last 450,000 years, and may happen again.
