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…
(University of Tokyo) Newly discovered single-celled creatures living deep beneath the seafloor have provided clues about how to find life on Mars. These bacteria were discovered living in tiny cracks inside volcanic rocks after researchers perfected a new method cutting rocks into ultrathin slices to study under a microscope. Researchers estimate that the rock cracks are home to a community of bacteria as dense as that of the human gut, about 10 billion bacterial cells per cubic centimeter.
(Iowa State University) Backed by experimental data from a laboratory machine that simulates the huge forces involved in glacier flow, glaciologists have written an equation that accounts for the motion of ice that rests on the soft, deformable ground underneath unusually fast-moving parts of ice sheets. Models using the equation — a ‘slip law’ — could better predict how quickly glaciers are sliding, how much ice they’re sending to oceans and how that would affect sea-level rise.
A precise statistical analysis reveals that on the Åland Islands a powdery mildew fungus that is a common parasite of the ribwort plantain primarily spreads via roadsides because traffic raises the spores found on roadsides efficiently into the air.
(Smithsonian) A team of scientists reports March 30 in the journal Proceedings of the National Academy of Sciences how carbon behaved during Earth’s violent formative period. The findings can help scientists understand how much carbon likely exists in the planet’s core and the ways it influences chemical and dynamic activities that shape the world, including the convective motion that powers the magnetic field that protects Earth from cosmic radiation.
(King Abdullah University of Science & Technology (KAUST)) An international study recently published in the journal Nature that was led by KAUST professors Carlos Duarte and Susana Agustí lays out the essential roadmap of actions required for the planet’s marine life to recover to full abundance by 2050.
What keeps people awake at night? For baseball players, it might be a late-breaking fastball. It looks like you could hit it right out of the park until it curves.
A novel approach to geochemical measurements helps scientists reconstruct the past intensity of the methane seeps in the Arctic Ocean. Recent studies show that methane emissions fluctuated, strongly, in response to known periods of abrupt climate change at the end of the last glacial cycle.
