Published Researchers leveraging AI to train (robotic) dogs to respond to their masters
(via sciencedaily.com) Original source An international collaboration seeks to innovate the future of how a mechanical man's best friend interacts with its owner, using a combination of AI and edge computing called edge intelligence. The overarching project goal is to make the dog come 'alive' by adapting wearable-based sensing devices that can detect physiological and emotional stimuli inherent to one's personality and traits, such as introversions, or transient states, including pain and comfort levels.
Published New video test for Parkinson's uses AI to track how the disease is progressing
(via sciencedaily.com) Original source An automated assessment technique that uses artificial intelligence could revolutionize the management of Parkinson's disease.
Published Dual action antibiotic could make bacterial resistance nearly impossible
(via sciencedaily.com) Original source New drug that disrupts two cellular targets would make it much harder for bacteria to evolve resistance.
Published New rapid method for determining virus infectivity
(via sciencedaily.com) Original source A new method that can rapidly determine whether a virus is infectious or non-infectious could revolutionize the response to future pandemics, researchers report.
Published Development of 'living robots' needs regulation and public debate
(via sciencedaily.com) Original source Researchers are calling for regulation to guide the responsible and ethical development of bio-hybrid robotics -- a ground-breaking science which fuses artificial components with living tissue and cells.
Published B cell biohack: Immune cells to churn out custom antibodies
(via sciencedaily.com) Original source Scientists have discovered a way to turn the body's B cells into tiny surveillance machines and antibody factories that can pump out specially designed antibodies to destroy cancer cells or HIV, two of medicine's most formidable foes.
Published New genetic test will eliminate a form of inherited blindness in dogs
(via sciencedaily.com) Original source Scientists have identified the genetic mutation that causes progressive retinal atrophy in English Shepherd Dogs, which results in incurable blindness, and developed a genetic test to help eliminate the disease from future generations of the breed.
Published Exposing dengue's invasion strategies
(via sciencedaily.com) Original source Mosquito-borne viral infections once confined to tropical regions are spreading. Dengue virus infects up to 400 million people worldwide each year according to World Health Organization estimates, and no available treatments exist for this disease. Now, research uncovered surprising strategies for how dengue and hundreds of other viruses replicate in their hosts, with the potential to aid in developing novel antiviral treatments and vaccines.
Published Controlling mosquito populations through genetic breeding
(via sciencedaily.com) Original source Researchers have found a new way to identify genetic targets useful for control of mosquito populations, potentially offering an alternative to insecticides. Their study focused on the genetic basis of species incompatibility. They crossed Ae. aegypti, a major global arboviral disease vector, and its sibling species, Ae. mascarensis, from the Indian Ocean. When offspring is crossed back with one parent, about 10 percent of the progeny becomes intersex and is unable to reproduce.
Published Transient structure in fly leg holds clue to insect shape formation
(via sciencedaily.com) Original source A little leg may reveal something big about how closely related insect species can drastically differ in body shape, according to a new study. The team imaged live cells of fruit flies in the last stages of development over several days and found a new structure that appears to help guide a section of the leg into its final shape.
Published Can consciousness exist in a computer simulation?
(via sciencedaily.com) Original source A new essay explores which conditions must be met for consciousness to exist. At least one of them can't be found in a computer.
Published Small animals acquire genes from bacteria that can produce antibiotics
(via sciencedaily.com) Original source A group of small, freshwater animals (bdelloid rotifers) protect themselves from infections using antibiotic recipes 'stolen' from bacteria, according to new research. This raises the potential that rotifers are producing novel antimicrobials that may be less toxic to animals, including humans, than those we develop from bacteria and fungi.
Published Minerals play newly discovered role in Earth's phosphorus cycle
(via sciencedaily.com) Original source Plants and microbes are known to secrete enzymes to transform organic phosphorus into bioavailable inorganic phosphorus. Now, researchers found that iron oxide in soil performs the same transformation. Discovery is important for food security, which requires phosphorus as a crop fertilizer.
Published Although tiny, peatland microorganisms have a big impact on climate
(via sciencedaily.com) Original source Polyphenols are generally toxic to microorganisms. In peatlands, scientists thought microorganisms avoided this toxicity by degrading polyphenols using an oxygen-dependent enzyme, and thus that low-oxygen conditions inhibit microbes' carbon cycling. However, a new study found that Arctic peatland microorganisms used alternative enzymes, with and without oxygen, to break down polyphenols. This suggests carbon stored in these ecosystems is more at risk than previously thought.
Published Ant insights lead to robot navigation breakthrough
(via sciencedaily.com) Original source Have you ever wondered how insects are able to go so far beyond their home and still find their way? The answer to this question is not only relevant to biology but also to making the AI for tiny, autonomous robots. Drone-researchers felt inspired by biological findings on how ants visually recognize their environment and combine it with counting their steps in order to get safely back home. They have used these insights to create an insect-inspired autonomous navigation strategy for tiny, lightweight robots. It allows such robots to come back home after long trajectories, while requiring extremely little computation and memory (0.65 kiloByte per 100 m). In the future, tiny autonomous robots could find a wide range of uses, from monitoring stock in warehouses to finding gas leaks in industrial sites.
Published Ancient viruses fuel modern-day cancers
(via sciencedaily.com) Original source The human genome is filled with flecks of DNA left behind by viruses that infected primate ancestors tens of millions of years ago. Scientists used to think they were harmless, but new research shows that, when reawakened, they help cancer survive and thrive.
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 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 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.
