Published Changes in marine ecosystems going undetected


Existing ways of calculating biodiversity dynamics are not very effective in detecting wholesale species community change due to the effects of ocean acidification.
Published Scientists find link between fast-melting Arctic ice and ocean acidification


An international team of researchers has found acidity levels increasing three to four times faster than ocean waters elsewhere and a strong correlation between the accelerated rate of melting ice in the region and the rate of ocean acidification. This threatens the Earth's climate and the survival of plants, shellfish, coral reefs and other marine life.
Published Study links cold water shock to catastrophic coral collapse in the Eastern Pacific


Scientists have discovered that an extreme weather event that resulted in rapid sea temperature drops of up to 10 degrees was the primary cause of a catastrophic coral die-off event off the coast of Costa Rica.
Published Population boom near globe's vulnerable coral reefs


Millions more people across the globe are relying on our endangered coral reefs than 20 years ago, according to new figures into population growth in coastal areas.
Published More reasons to go solar when gearing up for a greener drive


With electric vehicles sales soaring worldwide, potential buyers are not just weighing up the price tag, but also the logistics and expense of charging the planet-friendly cars. A new study shows households with solar panels and batteries will be the big winners.
Published Cattle grazing with virtual fencing shows potential to create wildfire fuel breaks, study finds


The use of virtual fencing to manage cattle grazing on sagebrush rangelands has the potential to create fuel breaks needed to help fight wildfires, a recent study found.
Published Magnetic field helps thick battery electrodes tackle electric vehicle challenges


As electric vehicles grow in popularity, the spotlight shines more brightly on some of their remaining major issues. Researchers are tackling two of the bigger challenges facing electric vehicles: limited range and slow recharging.
Published Warming oceans are changing Australian reef fish populations


Shallow reefs and the creatures that inhabit them are changing due to rising ocean temperatures, but these impacts have been obscured by a lack of comprehensive local data. A team of researchers has been tracking changes in the country's reefs for over a decade, and they now describe how they used fine-scale data to illustrate how warming waters impact tropical and temperate reef fish communities differently.
Published Anthropogenic air pollution more significant than desert dust


At the beginning of the year, the World Health Organization (WHO) announced that the Middle East ranks among the regions with the worst air quality. There is a common misconception that desert dust is the most significant cause of air pollution from particulate matter in this region, but a new study has shown that more than 90 percent of the particulate matter that is detrimental to health originates from anthropogenic sources. This human-made fine particulate matter differs from the less harmful desert dust particles. Scientists determined this through ship borne measurements and verified it in elaborate modeling calculations. The anthropogenic particles are primarily caused by the production and use of fossil fuels such as oil and gas. They are generally smaller than desert dust and can penetrate deep into the lungs.
Published Scientists believe evolution could save coral reefs, if we let it


Coral reefs can adapt to climate change if given the chance to evolve, according to a study.
Published Cobalt-free cathode for lithium-ion batteries


Researchers offer a new mixture of metallic elements to serve as lithium-ion cathodes. This 'high-entropy doping strategy' is part of an effort to remove cobalt -- and expensive and geopolitically problematic mineral -- from LI batteries.
Published Hibernating bears' ability to regulate insulin narrowed down to eight proteins


Feeding honey to hibernating bears helped researchers find the potential genetic keys to the bears' insulin control, an advance that could ultimately lead to a treatment for human diabetes. Every year, bears gain an enormous amount of weight, then barely move for months, behavior that would spell diabetes in humans, but not for bears whose bodies can turn insulin resistance on and off almost like a switch. In the hunt for the bears' secret, scientists observed thousands of changes in gene expression during hibernation, but now a research team has narrowed that down to eight proteins.
Published Researchers discover expanding and intensifying low-oxygen zone in the Arabian gulf


Researchers have studied the emergence of hypoxia -- low oxygen levels -- in the Gulf over three decades, a stressor on the health of marine life in the region and the larger ecosystem.
Published Refreezing poles feasible and cheap, new study finds


Refreezing the poles by reducing incoming sunlight would be both feasible and remarkably cheap, according to new research.
Published Identifying research priorities for security and safety threats in the Arctic and the North-Atlantic


A new method has been developed for identifying and prioritizing research activities related to maritime safety and security issues for the Arctic and the North-Atlantic (ANA) region.
Published Is climate change disrupting maritime boundaries?


Coral reef islands and their reefs -- found across in the Indo-Pacific -- naturally grow and shrink due to complex biological and physical processes that have yet to be fully understood. Now, climate change is disrupting them further, leading to new uncertainties for legal maritime zones and small island states. Rising sea levels, coupled with the natural variability of atoll islands and coral reefs, is creating new uncertainty in international law, with geopolitical implications.
Published Climate models unreliable in predicting wave damage to coral reefs


A new study finds that climate models are unreliable when it comes to predicting the damage that tropical cyclones will do to sensitive coral reefs.
Published Climate change threatens ice caves in Austria


Eight ice caves in four Austrian federal states: A team of geologists has comprehensively documented the loss and gain of ice in Alpine ice caves over the last 2000 years for the first time. The geologists warn: The ice of smaller caves especially is in danger of disappearing in the near future and with it a valuable climate archive.
Published High-accuracy electric vehicle battery monitoring with diamond quantum sensors for driving range extension


The issue of battery usage inefficiency in electric vehicles resulting from an inaccurate battery charge measurement may finally get resolved, thanks to a diamond quantum sensor prototype. The sensor can measure currents in a wide range as well as detect milliampere-level currents in a noisy environment, improving the detection accuracy from 10% to within 1%.
Published Robo-bug: A rechargeable, remote-control cyborg cockroach


Researchers have engineered a system for creating remote controlled cyborg cockroaches, equipped with a tiny wireless control module that is powered by a rechargeable battery attached to a solar cell. This achievement will help make the use of cyborg insects a practical reality.
