Like ancient mariners, ancestors of Prochlorococcus microbes rode out to sea on exoskeleton particles      (via sciencedaily.com)     Original source 

Throughout the ocean, billions upon billions of plant-like microbes make up an invisible floating forest. As they drift, the tiny organisms use sunlight to suck up carbon dioxide from the atmosphere. Collectively, these photosynthesizing plankton, or phytoplankton, absorb almost as much CO2 as the world’s terrestrial forests. A measurable fraction of their carbon-capturing muscle comes from Prochlorococcus — an emerald-tinged free-floater that is the most abundant phytoplankton in the oceans today. New research suggests the microbe's ancient coastal ancestors colonized the ocean by rafting out on chitin particles.

Hammerhead sharks hold their breath on deep water hunts to stay warm      (via sciencedaily.com)     Original source 

Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.

Giants of the Jurassic seas were twice the size of a killer whale      (via sciencedaily.com)     Original source 

There have been heated debates over the size of Jurassic animals. The speculation was set to continue, but now a chance discovery in an Oxfordshire museum has led to palaeontologists publishing a paper on a Jurassic species potentially reaching a whopping 14.4 meters -- twice the size of a killer whale.

African rhinos share retroviruses not found in Asian rhinos or other related species      (via sciencedaily.com)     Original source 

Rhinoceros belong to a mammalian order called odd-toed ungulates that also include horses and tapirs. They are found in Africa and Asia. Until recently, evidence suggested that throughout their evolutionary history, gamma-retroviruses such as Murine leukemia virus had not colonized their genomes, unlike most other mammalian orders. The colonization process is called retroviral endogenization and has resulted in most mammalian genomes being comprised of up to ten percent retroviral like sequences.

Kangaroo Island ants 'play dead' to avoid predators      (via sciencedaily.com)     Original source 

They're well known for their industrious work, but now a species of ant on Kangaroo Island is also showing that it is skilled at 'playing dead', a behavior that researchers believe is a recorded world first.

Basic 'toolkit' for organ development is illuminated by sea star      (via sciencedaily.com)     Original source 

One of the basic and crucial embryonic processes to unfold in virtually every living organism is the formation of hollow, tubular structures that go on to form blood vessels or a digestive tract, and through branching and differentiation, complex organs including the heart and kidneys. This study illuminates fundamental design principles of tubulogenesis for all chordates, including mammals.

Earth's first animals had particular taste in real estate      (via sciencedaily.com)     Original source 

Even without body parts that allowed for movement, new research shows -- for the first time -- that some of Earth's earliest animals managed to be picky about where they lived.

Researchers close to unleashing rapeseed's protein power for human consumption      (via sciencedaily.com)     Original source 

Half of plant proteins in the EU come from rapeseed plants. Until now, the plant has only been used for oil and animal feed, as it is both bitter and unsafe for human consumption. In a new study, researchers have gotten closer to removing the plant's bitter substances, and in doing so, are paving the way for a new protein source to support the green transition.

Gutless marine worms on a Mediterranean diet: Animals can synthesize phytosterols      (via sciencedaily.com)     Original source 

Phytosterols are good for your health, but humans and other animals are not able to make them themselves, only plants can. To acquire phytosterols, humans are increasingly turning to supplements, green smoothies, or a Mediterranean diet with plenty of plant-based foods. Researchers have now discovered that tiny gutless worms from the Mediterranean can synthesize phytosterols on their own. Their study provides evidence that many other animals also have the genes needed to make their own phytosterols.

How seaweed has been misleading scientists about reef health      (via sciencedaily.com)     Original source 

For decades, scientists have used the amount of seaweed at the ocean's surface as a proxy for the health of coral reefs below. However, a new global study of more than 1,200 marine locations over a 16-year period reveals that this approach has been misleading -- and may even have hidden signs of reef stress.

Indo-Pacific corals more resilient to climate change than Atlantic corals      (via sciencedaily.com)     Original source 

In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team has found that these mutualistic relationships from the Indo-Pacific may be more flexible and ultimately resilient to higher ocean temperatures than those in the Atlantic.

'Zero plant extinction' is possible, says plant ecologist      (via sciencedaily.com)     Original source 

Like animals, many plant species are struggling to adapt to a human-dominated planet. However, plants are often overlooked in conservation efforts, even though they are cheaper and easier to protect than animals and play a pivotal role in bolstering our food, fuel, and medical systems. A plant ecologist suggests an approach for preventing all future land plant extinctions across the globe which includes training more plant experts, building an online 'metaherbarium,' and creating 'microreserves.'
