Study reveals how humanity could unite to address global challenges      (via sciencedaily.com)     Original source 

New research has found that perceptions of globally shared life experiences and globally shared biology can strengthen psychological bonding with humanity at large, which can motivate prosocial action on a global scale and help to tackle global problems.

Fires pose growing worldwide threat to wildland-urban interface      (via sciencedaily.com)     Original source 

Fires that devastate wildland-urban interface areas are becoming more common around the globe, a trend that is likely to continue for at least the next two decades, new research finds. Such fires are especially dangerous, both because they imperil large numbers of people and because they emit far more toxins than forest and grassland fires.

Yellowstone Lake ice cover unchanged despite warming climate      (via sciencedaily.com)     Original source 

While most lakes around the world are experiencing shorter durations of ice cover, the length of time that Yellowstone Lake is covered by ice each year has not changed in the past century, possibly due to increased snowfall.

Florida Wildlife Corridor eases worst impacts of climate change      (via sciencedaily.com)     Original source 

Florida is projected to lose 3.5 million acres of land to development by 2070. A new study highlights how Florida can buffer itself against both climate change and population pressures by conserving the remaining 8 million acres of 'opportunity areas' within the Florida Wildlife Corridor (FLWC), the only designated statewide corridor in the U.S. Interactions between the FLWC and climate change had not been previously examined until now. Findings show substantial climate resilience benefits from the corridor, yielding a much higher return on investment than originally thought. About 90 percent of Floridians live within 20 miles of the corridor.

Seed ferns: Plants experimented with complex leaf vein networks 201 million years ago      (via sciencedaily.com)     Original source 

According to a research team led by palaeontologists, the net-like leaf veining typical for today's flowering plants developed much earlier than previously thought, but died out again several times. Using new methods, the fossilized plant Furcula granulifer was identified as such an early forerunner. The leaves of this seed fern species already exhibited the net-like veining in the late Triassic (around 201 million years ago).

Twisted pollen tubes induce infertility      (via sciencedaily.com)     Original source 

Plants with multiple sets of chromosomes, known as polyploids, are salt-tolerant or drought-resistant and often achieve higher yields. However, newly formed polyploid plants are often sterile or have reduced fertility and are unsuitable for breeding resistant lines. The reason is that the pollen tube in these plants grows incorrectly, which keeps fertilization from taking place. Pollen tube growth is mainly controlled by two genes that could be useful in crop breeding.

Millions of gamers advance biomedical research      (via sciencedaily.com)     Original source 

4.5 million gamers around the world have advanced medical science by helping to reconstruct microbial evolutionary histories using a minigame included inside the critically and commercially successful video game, Borderlands 3. Their playing has led to a significantly refined estimate of the relationships of microbes in the human gut. The results of this collaboration will both substantially advance our knowledge of the microbiome and improve on the AI programs that will be used to carry out this work in future.

Evolution's recipe book: How 'copy paste' errors cooked up the animal kingdom      (via sciencedaily.com)     Original source 

A series of whole genome and gene duplication events that go back hundreds of millions of years have laid the foundations for tissue-specific gene expression, according to a new study. The 'copy-paste' errors allowed animals to keep one copy of their genome or genes for fundamental functions, while the second copy could be used as raw material for evolutionary innovation. Events like these, at varying degrees of scale, occurred constantly throughout the bilaterian evolutionary tree and enabled traits and behaviours as diverse as insect flight, octopus camouflage and human cognition.

How seaweed became multicellular      (via sciencedaily.com)     Original source 

A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or 'seaweed,' to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods by acquiring genes that enable cell adhesion, extracellular matrix formation, and cell differentiation, researchers report. Surprisingly, many of these multicellular-enabling genes had viral origins. The study, which increased the total number of sequenced macroalgal genomes from 14 to 124, is the first to investigate macroalgal evolution through the lens of genomics.

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.

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.
