Published Extremely rare bird captured on film
(via sciencedaily.com) Original source A striking and extremely rare half-female, half-male bird has been spotted by a zoologist.
Published 'Energy droughts' in wind and solar can last nearly a week
(via sciencedaily.com) Original source Understanding the risk of compound energy droughts -- times when the sun doesn't shine and the wind doesn't blow -- will help grid planners understand where energy storage is needed most.
Published Clinical trial demonstrates that the ketogenic diet is effective at controlling polycystic kidney disease
(via sciencedaily.com) Original source It's official: The ketogenic diet proved to be effective at controlling polycystic kidney disease (PKD) in the first randomized controlled clinical trial of ketogenic metabolic therapy for PKD.
Published Rail industry urged to consider safety risks of space weather
(via sciencedaily.com) Original source Train accidents could be caused by solar storms switching signalling from red to green according to new research examining the impact of space weather. Solar storms can trigger powerful magnetic disturbances on Earth, creating geomagnetically induced currents which could potentially interfere with electricity transmission and distribution grids. A study of two rail lines showed that more serious 'wrong side' failures (red to green) could occur with a weaker solar storm than for 'right side' failures, posing a serious risk which the industry needs to take on board.
Published Zika's shape-shifting machinery, and a possible vulnerability
(via sciencedaily.com) Original source Viruses have limited genetic material -- and few proteins -- so all the pieces must work extra hard. Zika is a great example; the virus only produces 10 proteins. Now researchers have shown how the virus does so much with so little and may have identified a therapeutic vulnerability.
Published Climate change will increase wildfire risk and lengthen fire seasons
(via sciencedaily.com) Original source Wildfires are some of the most destructive natural disasters in the country, threatening lives, destroying homes and infrastructure, and creating air pollution. In order to properly forecast and manage wildfires, managers need to understand wildfire risk and allocate resources accordingly.
Published How immune cells recognize their enemies
(via sciencedaily.com) Original source In order for immune cells to do their job, they need to know against whom they should direct their attack. Research teams a have identified new details in this process.
Published Breakthrough nanobody technology against liver inflammation
(via sciencedaily.com) Original source Researchers have developed a technique based on nanobody technology to prevent liver inflammation. Nanobodies, or single-domain antibodies, are fragments of antibodies that can selectively bind to a specific antigen. Because they are simple to produce and react in very specific ways, they are often used in various biotechnological, therapeutic and diagnostic applications.
Published New genes can arise from nothing
(via sciencedaily.com) Original source The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers resolved outstanding questions regarding the origin of small regulatory genes, and described a mechanism that creates their DNA palindromes. Under suitable circumstances, these palindromes evolve into microRNA genes.
Published New insights into Zebra mussel attachment fibers offer potential solutions to combat invasive species, develop sustainable materials
(via sciencedaily.com) Original source A recent study has revealed that an unlikely event, occurring over 12 million years ago played an important role in shaping one of Canada's most damaging invasive species. Zebra and quagga mussels, belonging to the Dreissenid family, are widespread freshwater invasive species throughout North America that present a significant danger to native ecosystems by competing for resources. Using a fibrous anchor called a byssus, Dreissenid mussels contribute to biofouling on surfaces and obstruct intake structures in power stations and water treatment plants.
Published Molecular fossils shed light on ancient life
(via sciencedaily.com) Original source Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.
Published Manipulation of gut microbiota with flaxseed could reduce breast cancer risk
(via sciencedaily.com) Original source A new study demonstrates that the human gut microbiome may be a factor in breast health.
Published How ChatGPT could help first responders during natural disasters
(via sciencedaily.com) Original source Researchers train AI to accurately recognize addresses and other location descriptions in Hurricane Harvey social media posts.
Published Growing biofilms actively alter host environment
(via sciencedaily.com) Original source Dental plaque, gut bacteria and the slippery sheen on river rocks are all examples of biofilms, organized communities of microorganisms that colonize our bodies and the world around us. A new study reveals exactly how growing biofilms shape their environments and fine-tune their internal architecture to fit their surroundings. The findings may have implications for a wide variety of applications, from fighting disease to engineering new types of living active materials.
Published Tiny llama nanobodies neutralize different noroviruses: Can they improve human anti-viral therapies?
(via sciencedaily.com) Original source Researchers investigated a novel strategy to neutralize human noroviruses. They tested the ability of tiny antibodies produced by llamas, called nanobodies, to effectively neutralize human norovirus infection in the lab. The unexpected findings reveal that nanobodies could be developed as a therapeutic agent against human norovirus.
Published Fungus-fighting protein could help overcome severe autoimmune disease and cancer
(via sciencedaily.com) Original source A protein in the immune system programmed to protect the body from fungal infections is also responsible for exacerbating the severity of certain autoimmune diseases such as irritable bowel disease (IBS), type 1 diabetes, eczema and other chronic disorders, new research has found. The discovery could pave the way for new and more effective drugs, without the nasty side effects of existing treatments. In addition to helping to manage severe autoimmune conditions, the breakthrough could also help treat all types of cancer.
Published Influx of water and salts propel immune cells through the body
(via sciencedaily.com) Original source Researchers have shown that an influx of water and ions into immune cells allows them to migrate to where they're needed in the body.
Published Reverse metabolomics: New method finds biomarker for inflammatory bowel disease
(via sciencedaily.com) Original source Scientists' debut 'reverse metabolomics,' a groundbreaking approach to advancing microbiome research. They use the technique to discover hundreds of new human molecules, and a new biomarker and therapeutic target for inflammatory bowel disease.
Published Pregnant women are missing vital nutrients needed for them and their babies
(via sciencedaily.com) Original source Pregnant women eating modern diets are missing key nutrients needed for them and their babies, and this could get worse with the move to plant-based foods. Scientists surveying more than 1,700 women found most were missing vitamins usually found in meat and dairy, including B12, B6 and D, folic acid and riboflavin which are essential for the development of fetuses in the womb.
Published From infamy to ingenuity: Bacterial hijack mechanisms as advanced genetic tools
(via sciencedaily.com) Original source Researchers have uncovered the intricate molecular mechanism used by parasitic phytoplasma bacteria, known for inducing 'zombie-like' effects in plants.
