Older males out-compete young males outside breeding pairs, bird study shows      (via sciencedaily.com)     Original source 

Young male blue tits are less successful in fathering offspring outside their breeding pair, not because of a lack of experience, but because they are outcompeted by older males, researchers report.

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.

New tagging method provides bioadhesive interface for marine sensors on diverse, soft, and fragile species      (via sciencedaily.com)     Original source 

Tagging marine animals with sensors to track their movements and ocean conditions can provide important environmental and behavioral information. Existing techniques to attach sensors currently largely rely on invasive physical anchors, suction cups, and rigid glues. While these techniques can be effective for tracking marine animals with hard exoskeletons and large animals such as sharks, individuals can incur physiological and metabolic stress during the tagging process, which can affect the quality of data collection. A newly developed soft hydrogel-based bioadhesive interface for marine sensors, referred to as BIMS, holds promise as an effective, rapid, robust, and non-invasive method to tag and track all sorts of marine species, including soft and fragile species. The BIMS tagging, which is also simple and versatile, can help researchers better understand animal behavior while also capturing oceanographic data critical for helping to better understand some impacts of climate change and for resource management.

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.

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.

'One ring to rule them all': How actin filaments are assembled by formins      (via sciencedaily.com)     Original source 

Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing filament. Furthermore, the scientists elucidated the reasons for the different speeds at which the different formins promote this process.

Hidden threat: Global underground infrastructure vulnerable to sea-level rise      (via sciencedaily.com)     Original source 

As sea levels rise, coastal groundwater is lifted closer to the ground surface while also becoming saltier and more corrosive. A recent study compiled research from experts worldwide showing that in cities where there are complex networks of buried and partially buried infrastructure, interaction with this shallower and saltier groundwater exacerbates corrosion and failure of critical systems such as sewer lines, roadways, and building foundations.

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.
