Published Research questions value of sagebrush control in conserving sage grouse
(via sciencedaily.com)
Original source 
Sagebrush reduction strategies, including mowing and herbicide application, are often employed to enhance habitat for the greater sage grouse and other sagebrush-dependent species.
Published How coral reefs can survive climate change
(via sciencedaily.com)
Original source 
Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.
Published Human impact on wildlife even in protected areas
(via sciencedaily.com)
Original source 
The largest long-term standardized camera-trap survey to date finds that human activity impacts tropical mammals living in protected areas and sheds light on how different species are affected based on their habitat needs and anthropogenic stressors.
Published Do warmer temperatures make turtles better mothers?
(via sciencedaily.com)
Original source 
Warmer temperatures are known to make more turtle eggs become female hatchlings, but new research shows that those females also have a higher capacity for egg production, even before their sex is set. This finding may explain why many animals besides turtles have temperature-dependent sex determination and why the system persists, despite seeming like a risky strategy. It may also provide a troubling glimpse of what could lie ahead in a warming world.
Published Extinct warbler's genome sequenced from museum specimens
(via sciencedaily.com)
Original source 
The Bachman's warbler, a songbird that was last seen in North America nearly 40 years ago, was a distinct species and not a hybrid of its two living sister species, according a new study in which the full genomes of seven museum specimens of the bird were sequenced.
Published All the immunity, none of the symptoms
(via sciencedaily.com)
Original source 
Scientists found pairing specific diets with diarrheal disease-causing bacteria can create lasting immunity in mice without a need to ever experience symptoms. The findings pave the way for vaccine development that could reduce symptoms and mortality of diarrheal illness and other diseases in humans.
Published Drug decelerates bacterial race to antibiotic resistance
(via sciencedaily.com)
Original source 
Researchers report that, in laboratory cultures and animal models, a drug significantly reduces the ability of bacteria to develop antibiotic resistance, which might prolong antibiotic effectiveness.
Published Gloss is less effective camouflage in beetles compared to matte, according to latest study
(via sciencedaily.com)
Original source 
Heliconius butterflies' brains grew as they adopted novel foraging behaviors, scientists have found.
Published Combination therapy effective against canine melanoma
(via sciencedaily.com)
Original source 
A combination of radiotherapy followed by immunotherapy is a promising strategy for the treatment of oral malignant melanomas in dogs.
Published Researcher uses pressure to understand RNA dynamics
(via sciencedaily.com)
Original source 
Just as space holds infinite mysteries, when we zoom in at the level of biomolecules (one trillion times smaller than a meter), there is still so much to learn. Scientists are studying the conformational landscapes of biomolecules and how they modulate cell function. When biomolecules receive certain inputs, it can cause the atoms to rearrange and the biomolecule to change shape. This change in shape affects their function in cells, so understanding conformational dynamics is critical for drug development.
Published 'We're all Asgardians': New clues about the origin of complex life
(via sciencedaily.com)
Original source 
According to a new study, eukaryotes -- complex life forms with nuclei in their cells, including all the world's plants, animals, insects and fungi -- trace their roots to a common Asgard archaean ancestor. That means eukaryotes are, in the parlance of evolutionary biologists, a 'well-nested clade' within Asgard archaea, similar to how birds are one of several groups within a larger group called dinosaurs, sharing a common ancestor.
Published Are viruses keeping sea lice at bay in wild salmon?
(via sciencedaily.com)
Original source 
More than 30 previously unknown RNA viruses in sea lice have been identified. Sea lice are parasitic copepods (small crustaceans) found in many fresh and saltwater habitats, and have been implicated in the decline of wild salmon populations. The research sheds greater light on the types of viruses being carried by sea lice, and how the viruses and host are interacting.
Published The molecular control center of our protein factories
(via sciencedaily.com)
Original source 
Researchers have deciphered a biochemical mechanism that ensures that newly formed proteins are processed correctly when they leave the cell's own protein factories. This solves a decade-old puzzle in protein sorting.
Published The clue is in the glue -- Nature's secret for holding it together
(via sciencedaily.com)
Original source 
An obscure aquatic plant has helped to explain how plants avoid cracking up under the stresses and strains of growth.
Published Traditional methods cannot give us the insights we need to understand changing ecosystems
(via sciencedaily.com)
Original source 
If we want to face up to the challenges posed by climate change and other global environmental changes, we need to bring complexity science into the mix with ecology and biodiversity conservation.
Published Global analysis on pollinators in cities: Wild bees and butterflies are at particular risk
(via sciencedaily.com)
Original source 
Butterflies are being hit hardest by urban growth. Shrinking habitats and food availability are causing their populations to decline. The same applies to many wild bees that fly early in spring. According to a new study, pollination has not yet been impacted by this because honeybees, for example, can compensate for the reduction of urban pollinators. The study is the first comprehensive analysis of the subject and includes data from 133 studies. The results underline the importance of nature conservation measures in urban areas.
Published Glass sponge genome furnishes insights into evolution of biomineralization
(via sciencedaily.com)
Original source 
The genome of a glass sponge species suggests that silica skeletons evolved independently in several groups of sponges.
Published Studying herpes encephalitis with mini-brains
(via sciencedaily.com)
Original source 
The herpes simplex virus-1 can sometimes cause a dangerous brain infection. Combining an anti-inflammatory and an antiviral could help in these cases, report scientists.
Published Unraveling the connections between the brain and gut
(via sciencedaily.com)
Original source 
Engineers designed a technology to probe connections between the brain and the digestive tract. Using fibers embedded with a variety of sensors, as well as optogenetic stimulation, the researchers could control neural circuits connecting the gut and the brain, in mice.
Published A roadmap for gene regulation in plants
(via sciencedaily.com)
Original source 
For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and identifies a new library of DNA parts that can be used to optimize plants for bioenergy and agriculture.
