Pronghorn population declining due to human development      (via sciencedaily.com)     Original source 

A new article looked at 40 years of data collected on 40 pronghorn herds residing in the Wyoming Basin Shrub Steppe. Overall, 80% of the herds saw a decrease in productivity, and nearly 43% saw a significant decrease. After looking at a number of variables that could potentially contribute to the decline, the researchers identified the two most strongly associated: development of oil and gas resources and woody encroachment.

Gene flow in giraffes and what it means for their conservation      (via sciencedaily.com)     Original source 

Giraffes, with their bizarre body plan, have always held a special place in the minds of evolutionary biologists and non-experts alike. In a new study whole-genome sequencing data was used to investigate the evolutionary processes occurring within giraffes. In particular, the authors were interested in establishing whether different populations of giraffes really have been isolated from each other for extended periods of time, which is normally a requirement before new species can arise.

New study reveals transgenerational effects of pesticide linuron on frogs      (via sciencedaily.com)     Original source 

Grand-offspring of male frogs exposed to the pesticide linuron exhibited changes in their DNA that was linked to significant physiological impacts, a study reveals. The research highlights the profound transgenerational consequences of environmental pollution on amphibian populations, which are already under threat of extinction.

Good news for coral reef restoration efforts: Study finds 'full recovery' of reef growth within four years      (via sciencedaily.com)     Original source 

While the majority of the world's reefs are now under threat or even damaged potentially beyond repair, a new study offers some encouraging news: efforts to restore coral reefs not only increase coral cover, but they can also bring back important ecosystem functions, and surprisingly fast.

Reptile roadkill reveals new threat to endangered lizard species      (via sciencedaily.com)     Original source 

The chance sighting of a dead snake beside a sandy track in remote Western Australia, and the investigation of its stomach contents, has led researchers to record the first known instance of a spotted mulga snake consuming a pygmy spiny-tailed skink, raising concerns for a similar-looking, endangered lizard species.

Healable cathode could unlock potential of solid-state lithium-sulfur batteries      (via sciencedaily.com)     Original source 

Engineers developed a cathode material for lithium-sulfur (Li-S) batteries that is healable and highly conductive, overcoming longstanding challenges of traditional sulfur cathodes. The advance holds promise for bringing more energy dense and low-cost Li-S batteries closer to market.

Fossil named 'Attenborough's strange bird' was the first in its kind without teeth      (via sciencedaily.com)     Original source 

A new fossil, named 'Attenborough's strange bird' after naturalist and documentarian Sir David Attenborough, is the first of its kind to evolve a toothless beak. It's from a branch of the bird family tree that went extinct in the mass extinction 66 million years ago, and this strange bird is another puzzle piece that helps explain why some birds -- and their fellow dinosaurs -- went extinct, and others survived to today.

Unlocking the potential of lithium-ion batteries with advanced binders      (via sciencedaily.com)     Original source 

Lithium-ion batteries employ binders that encounter challenges such as poor conductivity and expansion during charging. In a recent study, scientists have developed a high-performing binder using poly(vinylphosphonic acid) for silicon oxide-based anodes in lithium-ion batteries. This binder offers enhanced performance as demonstrated by the superior durability, and discharging capacity of the anodes compared to conventional options. With patents filed internationally, this technology holds promise for broader applications in electric vehicles and beyond.

Lithium-ion batteries from drones might find second lives in less 'stressful' devices      (via sciencedaily.com)     Original source 

Taking flight can be stressful -- especially for a lithium-ion battery that powers a drone. Too much strain on these cells causes damage and shortens a device's overall lifespan. Research shows the potential to improve batteries in aerial electric vehicles that take off and land vertically. The team developed a new electrolyte to address these challenges and said the 'stressed out' batteries could also have second lives in less strenuous applications.
