Walleye struggle with changes to timing of spring thaw      (via sciencedaily.com)     Original source 

Walleye are one of the most sought-after species in freshwater sportfishing, a delicacy on Midwestern menus and a critically important part of the culture of many Indigenous communities. They are also struggling to survive in the warming waters of the Midwestern United States and Canada. According to a new study, part of the problem is that walleye are creatures of habit, and the seasons -- especially winter -- are changing so fast that this iconic species of freshwater fish can't keep up.

Low-Temperature Plasma used to remove E. coli from hydroponically grown crops      (via sciencedaily.com)     Original source 

In a new study, a team sterilized a hydroponic nutrient solution using low-temperature plasma generated from electricity and the oxygen in the atmosphere. This new sterilization technique may allow farmers to grow crops without the use of chemical pesticides, representing an important advance in agricultural technology for sustainable crop production.

Scientists use blue-green algae as a surrogate mother for 'meat-like' proteins      (via sciencedaily.com)     Original source 

Researchers have not only succeeded in using blue-green algae as a surrogate mother for a new protein -- they have even coaxed the microalgae to produce 'meat fiber-like' protein strands. The achievement may be the key to sustainable foods that have both the 'right' texture and require minimal processing.

Scientists propose new method for tracking elusive origins of CO2 emissions from streams      (via sciencedaily.com)     Original source 

A team of researchers that specializes in accounting for the carbon dioxide release by streams, rivers and lakes recently demonstrated that the chemical process known as 'carbonate buffering' can account for the majority of emissions in highly alkaline waters. Furthermore, carbonate buffering distorts the most commonly used method of tracking the origins of CO2 in streams. The research proposes a better method for tracking the origin of riverine CO2 emissions.

Scientists assemble a richer picture of the plight and resilience of the foothill yellow-legged frog      (via sciencedaily.com)     Original source 

Up to only a few inches in length, with a lemon-hued belly, the foothill yellow-legged frog may seem unassuming. But its range once stretched from central Oregon to Baja California. In 2023, it was listed under the federal Endangered Species Act. Its rapidly decreasing range is due in part to a fungal pathogen called Batrachochytrium dendrobatidis, or Bd, that has devastated amphibians around the world.

Birds and bee lessons as Pacific field trips also solve 'Michener's mystery'      (via sciencedaily.com)     Original source 

Eight new Pacific bee species and new insights into Fijian bird behaviour on Viti Levu Island have been described in new scientific studies. The research highlights the potential for species discovery, ecological and conservation knowledge and cultural engagement from Asia-Pacific research collaborations.

Predatory fish use rapid color changes to coordinate attacks      (via sciencedaily.com)     Original source 

Striped marlin are some of the fastest animals on the planet and one of the ocean's top predators. When hunting in groups, individual marlin will take turns attacking schools of prey fish one at a time. Now a new study helps to explain how they might coordinate this turn-taking style of attack on their prey to avoid injuring each other. The key, according to the new work, is rapid color changes.

Wetlands, parks and even botanical gardens among the best ways to cool cities during heatwaves      (via sciencedaily.com)     Original source 

Botanical gardens are not just beautiful -- they can cool the city air by 5 C during heatwaves, according to the most comprehensive review of its kind. Parks and wetlands have a similar effect.

Neurobiology: How bats distinguish different sounds      (via sciencedaily.com)     Original source 

Bats live in a world of sounds. They use vocalizations both to communicate with their conspecifics and for navigation. For the latter, they emit sounds in the ultrasonic range, which echo and enable them to create an 'image' of their surroundings. Neuroscientists have now discovered how Seba's short-tailed bat, a species native to South America, manages to filter out important signals from ambient sound and especially to distinguish between echolocation and communication calls.

Streams connected to groundwater show improved detoxification and microbial diversity      (via sciencedaily.com)     Original source 

Streams with ample connections to shallow groundwater flow-paths have greater microbial diversity and are more effective at preventing toxic forms of metals -- often products of upstream mining -- from entering and being transported downstream.

Snakes do it faster, better: How a group of scaly, legless lizards hit the evolutionary jackpot      (via sciencedaily.com)     Original source 

More than 100 million years ago, the ancestors of the first snakes were small lizards that lived alongside other small, nondescript lizards in the shadow of the dinosaurs.

Air pollution hides increases in rainfall      (via sciencedaily.com)     Original source 

In a new study, researchers broke down how human-induced greenhouse gas and aerosol emissions influence rainfall in the United States. Greenhouse gas emissions increase rainfall, while aerosols have a long-term drying effect as well as short-term impacts that vary with the seasons. As aerosols decrease, their long-term drying effect will likely diminish, causing rainfall averages and extremes to rapidly increase.

Scientists can tell where a mouse is looking and located based on its neural activity      (via sciencedaily.com)     Original source 

Researchers have paired a deep learning model with experimental data to 'decode' mouse neural activity. Using the method, they can accurately determine where a mouse is located within an open environment and which direction it is facing, just by looking at its neural firing patterns. Being able to decode neural activity could provide insight into the function and behavior of individual neurons or even entire brain regions.

Utah's Bonneville Salt Flats has long been in flux      (via sciencedaily.com)     Original source 

It has been long assumed that Utah's Bonneville Salt Flats was formed as its ancient namesake lake dried up 13,000 years ago. But new research has gutted that narrative, determining these crusts did not form until several thousand years after Lake Bonneville disappeared, which could have important implications for managing this feature that has been shrinking for decades to the dismay of the racing community and others who revere the saline pan 100 miles west of Salt Lake City. Relying on radiocarbon analysis of pollen found in salt cores, the study concludes the salt began accumulating between 5,400 and 3,500 years ago, demonstrating how this geological feature is not a permanent fixture on the landscape.

New cloud model could help with climate research      (via sciencedaily.com)     Original source 

When clouds meet clear skies, cloud droplets evaporate as they mix with dry air. A new study has succeeded in capturing what happens in a model. Ultimately, this could lead to more accurate climate modeling in the future.
