Published Baboons in captivity in Ancient Egypt: insights from collection of mummies
(via sciencedaily.com)
Original source 
Baboons were raised in captivity before being mummified in Ancient Egyptian sites, according to a new study.
Published Jays jump in while crows hold out for the treat
(via sciencedaily.com)
Original source 
New research has found that two similar species of birds behave very differently around their favorite food when they have company. Biologists compared the behavior of two species of corvids, Eurasian jays and New Caledonian crows, both capable of displaying self-control through delayed gratification. The researchers found that jays will settle for an immediate, less preferred food option when another bird is present, while crows will always hold out for their favorite food, regardless of the social context.
Published Greenhouse gases in oceans are altered by climate change impact on microbes
(via sciencedaily.com)
Original source 
The ocean is a global life-support system, and climate change causes such as ocean warming, acidification, deoxygenation, and nitrogen-deposition alter the delicate microbial population in oceans. The marine microbial community plays an important role in the production of greenhouse gases like nitrous oxide and methane. Scientists have explored the climate change impact on marine microbes. Their research helps raise awareness about climate change severity and the importance of ocean resources.
Published 'Shocking' discovery: Electricity from electric eels may transfer genetic material to nearby animals
(via sciencedaily.com)
Original source 
Researchers have discovered that electric eels can alter the genes of tiny fish larvae with their electric shock. Their findings help to better understand electroporation, a method by which genes can be transported using electricity.
Published Mice pass the mirror test, a classic indicator of self-recognition
(via sciencedaily.com)
Original source 
Researchers report that mice display behavior that resembles self-recognition when they see themselves in the mirror. When the researchers marked the foreheads of black-furred mice with a spot of white ink, the mice spent more time grooming their heads in front of the mirror -- presumably to try and wash away the ink spot. However, the mice only showed this self-recognition-like behavior if they were already accustomed to mirrors, if they had socialized with other mice who looked like them, and if the ink spot was relatively large.
Published Deep sea sensor reveals that corals produce reactive oxygen species
(via sciencedaily.com)
Original source 
A new sensor on the submersible Alvin discovered reactive oxygen species for the first time in deep-sea corals, broadening our understanding of fundamental coral physiology.
Published More than a meteorite: New clues about the demise of dinosaurs
(via sciencedaily.com)
Original source 
What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants.
Published More than 100 'magic mushroom' genomes point the way to new cultivars
(via sciencedaily.com)
Original source 
Scientists have amassed genome data for dozens of 'magic mushroom' isolates and cultivars, with the goal to learn more about how their domestication and cultivation has changed them. The findings may point the way to the production of intriguing new cultivars, say the researchers.
Published Earliest-known fossil mosquito suggests males were bloodsuckers too
(via sciencedaily.com)
Original source 
Researchers have found the earliest-known fossil mosquito in Lower Cretaceous amber from Lebanon. What's more, the well-preserved insects are two males of the same species with piercing mouthparts, suggesting they likely sucked blood. That's noteworthy because, among modern-day mosquitoes, only females are hematophagous, meaning that they use piercing mouthparts to feed on the blood of people and other animals.
Published Crocodile family tree mapped: New light shed on croc evolution
(via sciencedaily.com)
Original source 
Around 250 million years ago, 700 species of reptiles closely related to the modern-day crocodile roamed the earth, now new research reveals how a complex interplay between climate change, species competition and habitat can help explain why just 23 species of crocodile survive today.
Published Unlocking the secret strength of marine mussels
(via sciencedaily.com)
Original source 
How do you create strong, yet quick-release connections between living and non-living tissues? This is a question that continues to puzzle bioengineers who aim to create materials that bond together for advanced biomedical applications. Looking to nature for inspiration, this research zeroed in on the marine mussel byssus, a fibrous holdfast, which these bivalve mollusks use to anchor themselves in seashore habitats.
Published Genomic study sheds light on how carnivorous Asian pitcher plants acquired signature insect trap
(via sciencedaily.com)
Original source 
Scientists sequenced the genome of the East Asian pitcher plant, Nepenthes gracilis, a species of carnivorous plant related to Venus flytraps, as well as sundews, beets and spinach.
Published Snake skulls show how species adapt to prey
(via sciencedaily.com)
Original source 
By studying the skull shapes of dipsadine snakes, researchers have found how these species of snakes in Central and South America have evolved and adapted to meet the demands of their habitats and food sources.
Published Sea fireflies synchronize their sparkle to seek soulmates
(via sciencedaily.com)
Original source 
In sea fireflies' underwater ballet, the males sway together in perfect, illuminated synchronization, basking in the glow of their secreted iridescent mucus.
Published Rare ant species rediscovered in North Carolina trees
(via sciencedaily.com)
Original source 
There's a species of ant that is so rare, only a handful of records exist from across the entire eastern United States. North Carolina State University researcher Michelle Kirchner not only found these ants in the Triangle region of North Carolina, she is the first to document an entire colony for scientists, taxonomists and ant-thusiasts everywhere. It is the first time males of the species have been collected or photographed.
Published Broadband buzz: Periodical cicadas' chorus measured with fiber optic cables
(via sciencedaily.com)
Original source 
Through an emerging technology called distributed fiber optic sensing, cables bringing high-speed internet to American households can be used to detect temperature changes, vibrations, and even sound. And periodical cicadas -- the insects that emerge by the billions every 13 or 17 years and make a racket with their mating calls -- are loud enough to be detected. A new study shows how fiber optic sensing could open new pathways for charting populations of these famously ephemeral bugs.
Published The waxy surface protecting plants might hold the key to developing stronger crops
(via sciencedaily.com)
Original source 
Researchers have discovered that the waxy protective barrier around plants might play a role in sending chemical signals to other plants and insects.
Published how far can the wind can carry a plant's seeds? New model
(via sciencedaily.com)
Original source 
Playing an essential foundational role in an ecosystem, plants contribute to the well-being of human health by helping create resources like food and medicine. Therefore, to better understand how plants can maintain resiliency in the face of challenges like climate change, researchers recently developed an innovative mathematical model that can provide fast and reliable predictions of how far wind can carry a plant's seeds.
Published Unknown animals were leaving bird-like footprints in Late Triassic Southern Africa

Published How shifting climates may have shaped early elephants' trunks
(via sciencedaily.com)
Original source 
Researchers have provided new insights into how ancestral elephants developed their dextrous trunks. A study of the evolution of longirostrine gomphotheres, an ancestor of the modern day elephant, suggests moving into open-land grazing helped develop their coiling and grasping trunks.
