How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon      (via sciencedaily.com)     Original source 

How do birds fly in a coordinated and seemingly effortless fashion? Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports a team of mathematicians. Its breakthrough broadens our understanding of wildlife, including fish, who move in schools, and could have applications in transportation and energy.

Unveiling the lionfish invasion in the Mediterranean Sea      (via sciencedaily.com)     Original source 

Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.

These giant, prehistoric salmon had tusk-like teeth      (via sciencedaily.com)     Original source 

Oncorhynchus rastrosus, a giant species of salmon that lived in the North American Pacific Northwest a few million years ago, sported a pair of front teeth that projected out from the sides of its mouth like tusks, according to a new study.

Diversity and productivity go branch-in-branch      (via sciencedaily.com)     Original source 

Researchers found that forests with higher trait diversity not only adapt better to climate change but may also thrive. The study unveiled how tree functional trait diversity plays a pivotal role in mitigating climate warming. In the face of environmental stress, these diverse trees have been shown to maintain higher productivity levels, in contrast to monoculture forests.

Color variants in cuckoos: The advantages of rareness      (via sciencedaily.com)     Original source 

Every cuckoo is an adopted child -- raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morph that looks like a sparrowhawk, and a rufous morph. Male cuckoos are always gray.

Nanofibers rid water of hazardous dyes      (via sciencedaily.com)     Original source 

A special nanostructure has been developed to filter a widespread class of harmful dyes from water. A crucial component is a material that is considered waste: used cellulose, for example in the form of cleaning cloths or paper cups. The cellulose is utilized to coat a fine nano-fabric to create an efficient filter for polluted water.

Securing competitiveness of energy-intensive industries through relocation: The pulling power of renewables      (via sciencedaily.com)     Original source 

Countries with limited potential for renewables could save up to 20 percent of costs for green steel and up to 40 percent for green chemicals from green hydrogen if they relocated their energy-intensive production and would import from countries where renewable energy is cheaper.

How parasites shape complex food webs      (via sciencedaily.com)     Original source 

A new study sheds light on how parasites, often overlooked, can dramatically affect the balance between predator and prey populations. Researchers developed a groundbreaking mathematical framework that predicts when predators, prey, and parasites can coexist, considering factors like random fluctuations and parasite effects on both populations. This research provides a valuable tool for conservation by helping predict how parasites influence ecosystem resilience and informing strategies to protect vulnerable species.

This salt battery harvests osmotic energy where the river meets the sea      (via sciencedaily.com)     Original source 

Estuaries -- where freshwater rivers meet the salty sea -- are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, 'blue' osmotic energy. Researchers report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations.

Asian monsoon lofts ozone-depleting substances to stratosphere      (via sciencedaily.com)     Original source 

Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, according to new research. The study found that the East Asian Monsoon delivers more than twice the concentration of very short-lived ozone-depleting substances into the upper troposphere and lower stratosphere than previously reported.

Warming climate is putting more metals into Colorado's mountain streams      (via sciencedaily.com)     Original source 

Warming temperatures are causing a steady rise in copper, zinc and sulfate in the waters of Colorado mountain streams affected by acid rock drainage. Concentrations of these metals have roughly doubled in these alpine streams over the past 30 years, presenting a concern for ecosystems, downstream water quality and mining remediation, according to a new study. Natural chemical weathering of bedrock is the source of the rising acidity and metals, but the ultimate driver of the trend is climate change, the report found, and the results point to lower stream volumes and exposure of rock once sealed away by ice as the likely causes.
