Climate change is causing the Arctic Ocean's sea ice to melt away. When the polar ocean loses its cover of sea ice, carbon dioxide uptake increases disrupting the food web in the water according to a new study.

Drones show potential to improve salmon nest counts
A study showed that drone photography of the Wenatchee River during spawning season can be effective in estimating the number of rocky hollows salmon create to lay their eggs, also called 'redds.'
Large emissions from ship scrubbers
The Baltic Sea is considered one of the world's most polluted seas. Now, new research reveals a relatively unknown environmental culprit. The study shows that the discharge water from ships' exhaust gas treatment systems, so-called scrubbers, is responsible for up to nine percent of certain emissions of carcinogenic and environmentally...
Model calculates energetics of piercing fangs, claws and other biological weapons
Researchers have created a model that can calculate the energetics involved when one organism stabs another with its fangs, thorns, spines or other puncturing parts. Because the model can be applied to a variety of organisms, it will help scientists study and compare many types of biological puncturing tools, researchers...
Warming oceans likely to shrink the viable habitat of many marine animals — but not all
A new article adds a new chapter to the story of how some animals may respond to the warming oceans.
Attack on 2 fronts leads ocean bacteria to require carbon boost
The types of ocean bacteria known to absorb carbon dioxide from the air require more energy -- in the form of carbon -- and other resources when they're simultaneously infected by viruses and face attack from nearby predators, new research has found.
Nanoporous intermetallic compounds that boost hydrogen production
Hydrogen, a clean fuel, is incredibly dense in energy -- three times more than diesel or gasoline. Its ability to power a sustainable future has been hindered by a lack of high performing catalysts. Now, a collaborative research group has developed nanoporous molybdenum-based intermetallic compounds that could address this conundrum.
Reliably estimating proportion of vaccinated populations in wildlife
Researchers develop a ground-breaking model to estimate bait vaccination effectiveness in wild animals based on the proportion of immunized animals in a population and the number of vaccine applications.
Grazing Animals Key to Long-Term Soil Carbon Stability, Study Finds
Large mammalian herbivores like the yak and ibex play a crucial role in stabilising the pool of soil carbon in grazing ecosystems such as the Spiti region in the Himalayas, according to a 16-year-long study carried out by researchers at the Centre for Ecological Sciences (CES) and the Divecha Centre...
Scientists Discover Mechanism That Can Cause Collapse of Great Atlantic Circulation System
The Atlantic meridional overturning circulation (AMOC), a system of ocean currents that carry warm water from the tropics into the North Atlantic and transport cold water from the northern to the southern hemisphere, is a fundamental mechanism for the regulation of Earth’s climate.
