Image: Sathees94/Shutterstock.com Researchers wrestle with accuracy of AI technology used to create new drug candidates Researchers have determined that a protein prediction technology can yield accurate results in the hunt to efficiently find the best possible drug candidates for many conditions. How did sabre-toothed tigers acquire their long upper canine teeth? In a groundbreaking study an international team of scientists has investigated the evolutionary patterns behind the development of sabre teeth, with some unexpected results along the way. How does the brain turn waves of light into experiences of color? Perceiving something -- anything -- in your surroundings is to become aware of what your senses are detecting. Today, neuroscientists identify, for the first time, brain-cell circuitry in fruit flies that converts raw sensory signals into color perceptions that can guide behavior. Wind farms can offset their emissions within two years After spinning for under two years, a wind farm can offset the carbon emissions generated across its entire 30-year lifespan, when compared to thermal power plants. Celiac disease: New findings on the effects of gluten Celiac disease is a chronic autoimmune condition that occurs in around one per cent of the world's population. It is triggered by the consumption of gluten proteins from wheat, barley, rye and some oats. A gluten-free diet protects celiac patients from severe intestinal damage. Automated news video production is better with a human touch AI-generated videos for short messages are only as well received as manually created ones if they are edited by humans. Very early blood pressure control confers both benefits and harms in acute stroke Early identification of stroke type could be key to harnessing the benefits of very early in-ambulance blood pressure lowering treatment in patients with suspected acute stroke, according to new research. Shedding light on perovskite hydrides using a new deposition technique Perovskite hydrides are promising materials for various emerging energy technologies, but measuring their intrinsic hydride-ion conductivity is difficult. In a recent study, researchers address this issue using a novel laser deposition technique in an H-radical atmosphere. Using this approach, they grew thin-film single crystals of two different perovskite hydrides and characterized their hydride-ion conductivity. These efforts will bolster research on hydrogen-related materials. 'Forever chemicals' found to rain down on all five Great Lakes Perfluoroalkyl and polyfluoroalkyl substances, also known as PFAS or 'forever chemicals,' have become persistent pollutants in the air, water and soil. Because they are so stable, they can be transported throughout the water cycle, making their way into drinking water sources and precipitation. Precipitation introduces similar amounts of PFAS into each of the Great Lakes; however, the lakes eliminate the chemicals at different rates. Gene therapy relieves back pain, repairs damaged disc in mice Disc-related back pain may one day meet its therapeutic match: gene therapy delivered by naturally derived nanocarriers that, a new study shows, repairs damaged discs in the spine and lowers pain symptoms in mice. Why do we overindulge? If you tend to do other things or get distracted while eating dinner, you may be running the risk of over-consuming everyday pleasures later, possibly because the distraction caused you to enjoy yourself less, according to new research. Bioengineered enzyme creates natural vanillin from plants in one step Vanilla, the most widely used flavoring compound in confectionaries and cosmetics, gets its sweet flavor and aroma from the chemical compound -- 'vanillin'. However, the large-scale production of natural vanillin is impeded by the lack of microbial processes and enzymes which can commercially generate vanillin. Now, researchers have genetically engineered a novel enzyme which can convert ferulic acid from plant waste into vanillin in a one-step sustainable process. Regenerating worms have genetic control over their algal partners Researchers have found a genetic pathway that facilitates inter-species communication between a marine worm, acoel, and its symbiotic algae. 'Trojan horse' weight loss drug more effective than available therapies A groundbreaking article describes a promising new therapy for obesity that leads to greater weight loss in mice than existing medications. The approach smuggles molecules into the brain's appetite center and affects the brain's neuroplasticity. When saying 'please' is more strategic than magic By kindergarten age, most children have been taught that 'please' is a magic word. 'Please' is an expression of politeness that shows courtesy and respect, turning a potential demand into a request that will -- poof! -- magically be granted. But a new study on the ways people make requests of one another suggests that 'please' might not be an all-purpose marker of politeness, but rather a more focused, strategic tool to manage frictions or obstacles among family members, friends and even coworkers. The study shows that people say 'please' much less often than expected, and mostly when they expect a 'no' response is forthcoming. Jet-propelled sea creatures could improve ocean robotics Scientists have discovered that colonies of gelatinous sea animals swim through the ocean in giant corkscrew shapes using coordinated jet propulsion, an unusual kind of locomotion that could inspire new designs for efficient underwater vehicles. Climate change likely to aggravate brain conditions Climate change, and its effects on weather patterns and adverse weather events, is likely to negatively affect the health of people with brain conditions, argue a team of researchers. What is the carbon footprint of a house in Japan? Researchers conducted a comprehensive analysis on the carbon footprint of constructing a wooden house in Japan. The team found that the estimated carbon footprint of a house in Japan is 38 tons of CO2, with the largest share coming from the electric power sector at 32% of all emissions. Other sectors included were pig iron production at 12% of total emissions; cement, road freight transport, and private power generation each covering 7%. From roots to resilience: investigating the vital role of microbes in coastal plant health Understanding how salt marsh grass stays healthy is of crucial ecological importance, and studying the ways bacteria interact with these plants is key. Thanks to recent advances in genomic technology, biologists have begun to reveal never-before-seen ecological processes. Blood pressure drugs more than double bone-fracture risk in nursing home patients New research finds a link between common medications and life-threatening injuries. Pre- and post-surgical immunotherapy improves outcomes for patients with operable lung cancer Compared with pre-surgical (neoadjuvant) chemotherapy alone, adding perioperative immunotherapy -- given before and after surgery -- significantly improved event-free survival (EFS) in patients with resectable early-stage non-small cell lung cancer(NSCLC), according to researchers. Carbon-capture batteries developed to store renewable energy, help climate Researchers are developing battery technologies to fight climate change in two ways, by expanding the use of renewable energy and capturing airborne carbon dioxide. Researchers recently created and tested two different formulations for batteries that store renewable energy; when the energy is later used, an electrochemical reaction converts industrial carbon dioxide emissions into a solid form that has the potential to be used in other products. Temperature, time and blueberry wine Nutrient-rich blueberries -- a common breakfast smoothie ingredient -- can also create wine. But does the heat and time required to ferment this mighty berry strip out any of those potential health-promoting compounds? Researchers examine fermentation's effects on the bioactive compounds and antioxidant activity in blueberry wine. The results suggest blueberry wine maintains some of the fruit's nutrients and the team identifies ways to optimize components in this superfood tipple. Hubble views the dawn of a sun-like star Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that hasn't begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun. Robotic 'SuperLimbs' could help moonwalkers recover from falls SuperLimbs, a system of wearable robotic limbs, can physically support an astronaut and lift them back on their feet after a fall, helping them conserve energy for other essential tasks. Copper can't be mined fast enough to electrify the US Copper cannot be mined quickly enough to keep up with current U.S. policy guidelines to transition the country's electricity and vehicle infrastructure to renewable energy, according to a new study. What fire ants can teach us about making better, self-healing materials Fire ants form rafts to survive flooding, but how do those bonds work? And what can we learn from them? A professor is researching those questions to expand our knowledge of materials science. Making batteries takes a lot of lithium: Some could come from gas well wastewater A new analysis suggests that if it could be extracted with complete efficiency, lithium from the wastewater of Marcellus shale gas wells could supply up to 40% of the country's demand.
