Published Aussie innovation spearheads cheaper seafloor test for offshore wind farms
(via sciencedaily.com)
Original source 
Australian engineers have unveiled a clever new device -- based on a modified speargun -- as a cheap and efficient way to test seabed soil when designing offshore wind farms.
Published Paleolithic diets are not without risks
(via sciencedaily.com)
Original source 
High-protein diets, known as 'Paleolithic diets', are popular. Using mouse models, scientists have studied their impact. While effective in regulating weight and stabilizing diabetes, these diets are not without risks. Excess protein greatly increases ammonium production, overwhelming the liver. Excess ammonium can cause neurological disorders and, in severe cases, lead to coma. These results suggest caution when following these diets.
Published Children living in greener neighborhoods show better lung function
(via sciencedaily.com)
Original source 
A large study of 35,000 children from eight countries has found a 'robust' link between exposure to green spaces in early childhood and better lung function. The study used data from 10 European birth cohorts from 8 countries to conduct a meta-analysis. This assessment of the data was done at the individual level for each participant.
Published Powerful new particle accelerator a step closer with muon-marshalling technology
(via sciencedaily.com)
Original source 
New experimental results show particles called muons can be corralled into beams suitable for high-energy collisions, paving the way for new physics.
Published Physicists develop new theory describing the energy landscape formed when quantum particles gather together
(via sciencedaily.com)
Original source 
An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, opening up new routes to make computer simulation of materials much more accurate. This, in turn, may help scientists design a suite of materials that could revolutionize green technologies.
Published Designing safer opioids
(via sciencedaily.com)
Original source 
Opioid medications offer people relief from debilitating pain, but these drugs come with dangers: the risk for addiction, miserable withdrawal symptoms and the potential for fatal overdose. Researchers have now identified a strategy to design safer opioids. They showed that an experimental opioid, which binds to an unconventional spot in the receptor, suppresses pain in animal models with fewer side effects -- most notably those linked to fatal overdoses.
Published Completely stretchy lithium-ion battery for flexible electronics
(via sciencedaily.com)
Original source 
When you think of a battery, you probably don't think stretchy. But batteries will need this shape-shifting quality to be incorporated into flexible electronics, which are gaining traction for wearable health monitors. Now, researchers report a lithium-ion battery with entirely stretchable components, including an electrolyte layer that can expand by 5000%, and it retains its charge storage capacity after nearly 70 charge/discharge cycles.
Published What fat cats on a diet may tell us about obesity in humans
(via sciencedaily.com)
Original source 
Pet cats may be excellent animal models for the study of obesity origins and treatment in humans, a new study of feline gut microbes suggests -- and both species would likely get healthier in the research process, scientists say.
Published Researchers predict fewer, pricier strawberries as temperatures warm
(via sciencedaily.com)
Original source 
Strawberries could be fewer and more expensive because of higher temperatures caused by climate change, according to new research.
Published Smart soil can water and feed itself
(via sciencedaily.com)
Original source 
A newly engineered type of soil can capture water out of thin air to keep plants hydrated and manage controlled release of fertilizer for a constant supply of nutrients.
Published Cuttlefish can form false memories, too
(via sciencedaily.com)
Original source 
During an event, details like what you saw, smelled, and felt aren't stored as a single memory. Rather, they are encoded and stored in your brain separately. To retrieve that memory, those pieces must get put back together. When that doesn't happen in the right way or details are distorted, it can lead to the creation of false memories. Now researchers have evidence that the common cuttlefish may create false memories, too.
Published Astronomers spot a 'highly eccentric' planet on its way to becoming a hot Jupiter
(via sciencedaily.com)
Original source 
The newly discovered planet TIC 241249530 b has the most highly elliptical, or eccentric, orbit of any known planet. It appears to be a juvenile planet that is in the midst of becoming a hot Jupiter, and its orbit is providing some answers to how such large, scorching planets evolve.
Published Psilocybin generates psychedelic experience by disrupting brain network
(via sciencedaily.com)
Original source 
Researchers report that psilocybin, the active ingredient in magic mushrooms, destabilizes a critical network of brain areas involved in introspective thinking. The findings provide a neurobiological explanation for the drug's mind-bending effects.
Published Bridging the 'Valley of Death' in carbon capture
(via sciencedaily.com)
Original source 
PrISMa is a new platform that uses advanced simulations and machine learning to streamline carbon capture technologies, by taking into account the perspectives of diverse stakeholders early in the research process.
Published Forests endure as carbon sink despite regional pressures
(via sciencedaily.com)
Original source 
Despite facing regional threats like deforestation and wildfires, the world's forests continue to be a powerful weapon in the fight against climate change. A new study reveals these vital ecosystems have consistently absorbed carbon dioxide for the past three decades, even as disruptions chip away at their capacity. The study, based on long-term ground measurements combined with remote sensing data, found that forests take up an average of 3.5 0.4 billion metric tons of carbon per year, which is nearly half of the carbon dioxide emissions from burning fossil fuels between 1990 and 2019.
Published Paving the way to extremely fast, compact computer memory
(via sciencedaily.com)
Original source 
Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.
Published Logged forests can still have ecological value -- if not pushed too far
(via sciencedaily.com)
Original source 
Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.
Published Switching off inflammatory protein leads to longer, healthier lifespans in mice
(via sciencedaily.com)
Original source 
Scientists have discovered that 'switching off' a protein called IL-11 can significantly increase the healthy lifespan of mice by almost 25 percent.
Published Genome recording makes living cells their own historians
(via sciencedaily.com)
Original source 
Genomes can now be used to store information about a variety of transient biological events inside of living cells, as they happen, like a flight recorder collecting data from an aircraft. The method, called ENGRAM, aims to turn cells into their own historians. ENGRAM couples each kind of biological signal or event inside a cell to a symbolic barcode. This new strategy traces and archives the type and timing of biological signals inside the cell by inserting this information into the genome. For example, this record-keeping can track the commands that turn genes on or off.
Published Influenza viruses can use two ways to infect cells
(via sciencedaily.com)
Original source 
Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway, a protein complex of the immune system, to infect cells. This ability helps the viruses infect different species -- and potentially jump between animals and humans.
