New radar analysis method can improve winter river safety      (via sciencedaily.com)     Original source 

Researchers have developed a way to use radar to detect open water zones and other changes in Alaska's frozen rivers in the early winter. The approach can be automated to provide current hazard maps and is applicable across the Arctic and sub-Arctic.

Where have all the right whales gone?      (via sciencedaily.com)     Original source 

Marine researchers have mapped the density of one of the most endangered large whale species worldwide, the North Atlantic right whale, using new data to help avoid right whales' harmful exposure to commercial fisheries and vessel strikes. The resulting maps, spanning 20 years of whale observations, are publicly available to inform risk assessments, estimations of whale harm/disturbance, marine spatial planning, and industry regulations to mitigate risk to right whales.

Retention ponds can deliver a substantial reduction in tire particle pollution      (via sciencedaily.com)     Original source 

New research has shown that the presence of wetlands and retention ponds alongside major highways led to an average reduction of almost 75% in the mass of tire wear particles being discharged to aquatic waters. The researchers say that while the number of retention ponds and wetlands in the UK is quite small, the study has international significance as to the most effective ways to mitigate against the potential impacts of tire pollution on a global scale.

Africa's iconic flamingos threatened by rising lake levels      (via sciencedaily.com)     Original source 

It is one of the world's most spectacular sights -- huge flocks or 'flamboyances' of flamingos around East Africa's lakes -- as seen in the film Out of Africa or David Attenborough's A Perfect Planet. But new research has revealed how the lesser flamingo is at danger of being flushed out of its historic feeding grounds, with serious consequences for the future of the species.

Oxidant pollutant ozone removes mating barriers between fly species      (via sciencedaily.com)     Original source 

Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to ozone and produce hybrid offspring. Since most of these offspring are unable to reproduce, the results could provide another explanation for the global decline of insects.

Cloud engineering could be more effective 'painkiller' for global warming than previously thought      (via sciencedaily.com)     Original source 

Cloud 'engineering' could be more effective for climate cooling than previously thought, because of the increased cloud cover produced, new research shows.

Chemicals stored in home garages linked to ALS risk      (via sciencedaily.com)     Original source 

Storing chemicals in a garage at home may associate with an increased risk of ALS, a study finds. This comes as research has found that exposure to environmental toxins, such as pesticides and volatile organic compounds, are also linked to ALS development. Researchers call the buildup of exposures of the lifetime the ALS exposome.

New report 'braids' Indigenous and Western knowledge for forest adaptation strategies against climate change      (via sciencedaily.com)     Original source 

Forests could also be potential bulwarks against climate change. But, increasingly severe droughts and wildfires, invasive species, and large insect outbreaks -- all intensified by climate change -- are straining many national forests and surrounding lands in the United States. A report outlines a new approach to forest stewardship that 'braids together' Indigenous knowledge and Western science to conserve and restore more resilient forestlands.

3D mouth of an ancient jawless fish suggests they were filter-feeders, not scavengers or hunters      (via sciencedaily.com)     Original source 

Early jawless fish were likely to have used bony projections surrounding their mouths to modify the mouth's shape while they collected food. Experts have used CT scanning techniques to build up the first 3D pictures of these creatures, which are some of the earliest vertebrates (animals with backbones) in which the mouth is fossilized. Their aim was to answer questions about feeding in early vertebrates without jaws in the early Devonian epoch -- sometimes called the Age of Fishes -- around 400 million years ago.
