Even the simplest marine organisms tend to be individualistic      (via sciencedaily.com)     Original source 

Sport junkie or couch potato? Always on time or often late? The animal kingdom, too, is home to a range of personalities, each with its own lifestyle. Biologists report on a surprising discovery: even simple marine polychaete worms shape their day-to-day lives on the basis of highly individual rhythms. This diversity is of interest not just for the future of species and populations in a changing environment, but also for medicine.

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.

PFAS exposure from high seafood diets may be underestimated      (via sciencedaily.com)     Original source 

A study suggests that people with diets high in seafood may face a greater risk of exposure to PFAS -- the family of human-made toxins known as 'forever chemicals' -- than previously thought. The researchers stress the need for more stringent public health guidelines that establish how much seafood people can safely consume to limit their exposure, particularly in coastal areas where seafood is frequently eaten.

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.

New computer vision tool wins prize for social impact      (via sciencedaily.com)     Original source 

A team of computer scientists working on two different problems -- how to quickly detect damaged buildings in crisis zones and how to accurately estimate the size of bird flocks -- recently announced an AI framework that can do both. The framework, called DISCount, blends the speed and massive data-crunching power of artificial intelligence with the reliability of human analysis to quickly deliver reliable estimates that can quickly pinpoint and count specific features from very large collections of images.

Nanoscale movies shed light on one barrier to a clean energy future      (via sciencedaily.com)     Original source 

New research is shedding light on one barrier to a clean energy future: corrosion. Using nanoscale imaging techniques, researchers have captured high-resolution videos of tiny crystals of ruthenium dioxide -- a key ingredient used to produce clean-burning hydrogen -- as they are eaten away by their acidic environment. The research could pave the way to more durable catalysts and dramatically extend the lifetime of devices needed to turn hydrogen green.

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.

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.
