Sharks have depleted functional diversity compared to the last 66 million years      (via sciencedaily.com)     Original source 

New research has found that sharks retained high levels of functional diversity for most of the last 66 million years, before steadily declining over the last 10 million years to its lowest value in the present day.

Sweaty cattle may boost food security in a warming world      (via sciencedaily.com)     Original source 

Climate change is making it more difficult to raise cattle -- growth and reproduction are affected by heat -- so it's critical to breed cattle better adapted to a hotter and longer summer. A new study shows it's possible to identify the genes within breeds of cattle that would lead to the sweatiest, heat-tolerant offspring.

No bones about it: 100-million-year-old bones reveal new species of pterosaur      (via sciencedaily.com)     Original source 

New research has identified 100-million-year-old fossilized bones discovered in western Queensland as belonging to a newly identified species of pterosaur, which was a formidable flying reptile that lived among the dinosaurs.

Are plants intelligent? It depends on the definition      (via sciencedaily.com)     Original source 

Goldenrod can perceive other plants nearby without ever touching them, by sensing far-red light ratios reflected off leaves. When goldenrod is eaten by herbivores, it adapts its response based on whether or not another plant is nearby. Is this kind of flexible, real-time, adaptive response a sign of intelligence in plants?

Virus-like nanoparticles control the multicellular organization and reproduction of host bacteria      (via sciencedaily.com)     Original source 

Researchers have discovered that virus-like nanoparticles can promote the multicellular organization and reproduction of host bacteria. These particles, which are evolutionarily related to phages (viruses that infect bacteria), contain an enzyme that helps shape the multicellular architecture and ultimately enhances morphological differentiation.

Algae offer real potential as a renewable electricity source      (via sciencedaily.com)     Original source 

The need to transition away from fossil fuels to more sustainable energy production is critical. That's why a team of researchers is looking at a potential power source that not only produces no carbon emissions but removes carbon as it works: algae.

Scientists unlock secrets of how archaea, the third domain of life, makes energy      (via sciencedaily.com)     Original source 

An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how these tiny lifeforms make energy by consuming and producing hydrogen. This simple but dependable strategy has allowed them to thrive in some of Earth's most hostile environments for billions of years.

Novel Genetic Clock discovers oldest known marine plant      (via sciencedaily.com)     Original source 

An international research team has discovered the oldest known marine plant using a novel genetic clock. This 1400-year-old seagrass clone from the Baltic Sea dates back to the Migration Period. The research project is a significant step towards better understanding and protecting marine ecosystems.

Elephants have names for each other like people do, new study shows      (via sciencedaily.com)     Original source 

Wild African elephants address each other with name-like calls, a rare ability among nonhuman animals, according to a new study. Researchers used machine learning to confirm that elephant calls contained a name-like component identifying the intended recipient, a behavior they suspected based on observation. The study suggests elephants do not imitate the receiver's call to address one another but instead use arbitrary vocal labels like humans.

A new study reveals that marine cyanobacteria communicate      (via sciencedaily.com)     Original source 

A breakthrough study changes the way we understand cyanobacteria, which are essential for the sustenance of life. The study shows that these organisms do not operate in isolation, but rather physically interact through membrane-nanotubes, which function as exchange bridges between cells.

Researchers solve 2,000-year-old mystery of the shipworm      (via sciencedaily.com)     Original source 

They bedeviled ancient Greek navies, helped shipwreck Christopher Columbus, aided in the sinking of the Spanish Armada and caused the wharves in San Francisco Bay to collapse into the sea, but until now, scientists have been unable to pinpoint exactly how shipworms -- a family of mollusks -- are able to cause such damage. A team of researchers has discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the gut called the 'typhlosole,' have the ability to secrete the enzymes needed to digest lignin -- the toughest part of wood.
