Published Genetic hope in fight against devastating wheat disease
(via sciencedaily.com) Original source Fungal disease Fusarium head blight (FHB) is on the rise due to increasingly humid conditions induced by climate change during the wheat growing season, but a fundamental discovery could help reduce its economic harm.
Published Shoulder surgeons should rethink a common practice, study suggests
(via sciencedaily.com) Original source Many surgeons remove the bursa when repairing rotator cuff injuries, but a new animal study suggests that the small tissue helps with healing.
Published Barley plants fine-tune their root microbial communities through sugary secretions
(via sciencedaily.com) Original source Different types of barley recruit distinct communities of soil microbes to grow around their roots by releasing a custom mix of sugars and other compounds, according to a new study.
Published These jacks-of-all-trades are masters, too: Yeast study helps answer age-old biology question
(via sciencedaily.com) Original source The results suggest that internal -- not external -- factors are the primary drivers of variation in the types of carbon yeasts can eat, and the researchers found no evidence that metabolic versatility, or the ability to eat different foods, comes with any trade-offs. In other words, some yeasts are jacks-of-all-trades and masters of each.
Published Food in sight? The liver is ready!
(via sciencedaily.com) Original source What happens in the body when we are hungry and see and smell food? A team of researchers has now been able to show in mice that adaptations in the liver mitochondria take place after only a few minutes. Stimulated by the activation of a group of nerve cells in the brain, the mitochondria of the liver cells change and prepare the liver for the adaptation of the sugar metabolism. The findings could open up new avenues for the treatment of type 2 diabetes.
Published Curiosity promotes biodiversity
(via sciencedaily.com) Original source Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers. This trait influences the cichlids' ability to adapt to new habitats.
Published Herring arrives earlier in the Wadden Sea due to climate change
(via sciencedaily.com) Original source Due to the changing climate, young herring arrive in the Wadden Sea earlier and earlier in spring.
Published With hybrid brains, these mice smell like a rat
(via sciencedaily.com) Original source Mice lacking an olfactory system have had their sense of smell restored with neurons from rats, the first time scientists have successfully integrated the sensory apparatus of one species into another.
Published Synthetic droplets cause a stir in the primordial soup
(via sciencedaily.com) Original source Our bodies are made up of trillions of different cells, each fulfilling their own unique function to keep us alive. How do cells move around inside these extremely complicated systems? How do they know where to go? And how did they get so complicated to begin with? Simple yet profound questions like these are at the heart of curiosity-driven basic research, which focuses on the fundamental principles of natural phenomena.
Published Scientists replace fishmeal in aquaculture with microbial protein derived from soybean processing wastewater
(via sciencedaily.com) Original source Scientists have successfully replaced half of the fishmeal protein in the diets of farmed Asian seabass with a 'single cell protein' cultivated from microbes in soybean processing wastewater, paving the way for more sustainable fish farming practices.
Published How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon
(via sciencedaily.com) Original source How do birds fly in a coordinated and seemingly effortless fashion? Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports a team of mathematicians. Its breakthrough broadens our understanding of wildlife, including fish, who move in schools, and could have applications in transportation and energy.
Published Advanced cell atlas opens new doors in biomedical research
(via sciencedaily.com) Original source Researchers have developed a web-based platform that offers an unprecedented view of the human body at the cellular level. The aim is to create an invaluable resource for researchers worldwide to increase knowledge about human health and disease.
Published How immune cells communicate to fight viruses
(via sciencedaily.com) Original source Chemokines are signalling proteins that orchestrate the interaction of immune cells against pathogens and tumors. To understand this complex network, various techniques have been developed to identify chemokine-producing cells. However, it has not yet been possible to determine which cells react to these chemokines. Researchers have now developed a new class of genetically modified mice that enables the simultaneous identification of chemokine producers and sensors.
Published Unveiling the lionfish invasion in the Mediterranean Sea
(via sciencedaily.com) Original source Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.
Published Artificial intelligence helps scientists engineer plants to fight climate change
(via sciencedaily.com) Original source Scientists are using artificial intelligence software to analyze plant root systems, laying out a protocol that can be applied to gather data on crop and model plant phenotypes (physical characteristics) more efficiently and with equal or greater accuracy than existing methods.
Published After spinal cord injury, neurons wreak havoc on metabolism
(via sciencedaily.com) Original source Conditions such as diabetes, heart attack and vascular diseases commonly diagnosed in people with spinal cord injuries can be traced to abnormal post-injury neuronal activity that causes abdominal fat tissue compounds to leak and pool in the liver and other organs, a new animal study has found.
Published Cells may possess hidden communication system
(via sciencedaily.com) Original source Cells constantly navigate a dynamic environment, facing ever-changing conditions and challenges. But how do cells swiftly adapt to these environmental fluctuations? A new study is answering that question by challenging our understanding of how cells function. A team of researchers suggests that cells possess a previously unknown information processing system that allows them to make rapid decisions independent of their genes.
Published These giant, prehistoric salmon had tusk-like teeth
(via sciencedaily.com) Original source Oncorhynchus rastrosus, a giant species of salmon that lived in the North American Pacific Northwest a few million years ago, sported a pair of front teeth that projected out from the sides of its mouth like tusks, according to a new study.
Published Researchers uncover 'parallel universe' in tomato genetics
(via sciencedaily.com) Original source Researchers have made a breakthrough for evolutionary biology of the Solanaceae family, which includes peppers, potatoes and petunias.
Published Color variants in cuckoos: The advantages of rareness
(via sciencedaily.com) Original source Every cuckoo is an adopted child -- raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morph that looks like a sparrowhawk, and a rufous morph. Male cuckoos are always gray.
