Published Less social with age
(via sciencedaily.com) Original source Scientists tested several hypotheses on the drivers of social aging in free-living Assamese macaques in Thailand. The researchers collected data on the social behavior of females for eight years and found that the size of their social networks decreases with increasing age. The females continued to interact with their close social partners, but gradually withdrew from social interactions altogether. The results contribute to the understanding of the evolutionary origins of social aging.
Published Even inactive smokers are densely colonized by microbial communities
(via sciencedaily.com) Original source Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.
Published Arctic nightlife: Seabird colony bursts with sound at night
(via sciencedaily.com) Original source Acoustic recordings of a colony of little auks reveal their nocturnal activities and offer valuable monitoring means for avian biology in the Arctic.
Published DNA origami-based vaccines toward safe and highly-effective precision cancer immunotherapy
(via sciencedaily.com) Original source Researchers have created a DNA origami platform called DoriVac, whose core component is a self-assembling square block-shaped nanostructure. DoriVac vaccines enabled tumor-bearing mice to better control the growth of tumors and to survive significantly longer than control mice.
Published The atlas of unburnable oil in the world
(via sciencedaily.com) Original source In order to limit the increase in global average temperature to 1.5 C, it is essential to drastically reduce carbon dioxide emissions in the atmosphere. This would mean not exploiting most of the existing coal, conventional gas and oil energy resources in regions around the world, according to new research. The study presents the atlas of unburnable oil in the world, a world map designed with environmental and social criteria that warns which oil resources should not be exploited to meet the commitments of the Paris Agreement signed in 2015 to mitigate the effects of climate change.
Published Machine learning classifier accelerates the development of cellular immunotherapies
(via sciencedaily.com) Original source Making a personalized T cell therapy for cancer patients currently takes at least six months. Scientists have shown that the laborious first step of identifying tumor-reactive T cell receptors for patients can be replaced with a machine learning classifier that halves this time.
Published Protein fragments ID two new 'extremophile' microbes--and may help find alien life
(via sciencedaily.com) Original source Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.
Published Shark-bitten orcas in the Northeastern Pacific could be a new population of killer whale
(via sciencedaily.com) Original source Researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit that the 49 orcas could belong to a subpopulation of transient killer whales or a unique oceanic population found in waters off the coast of California and Oregon.
Published Breakthrough could make automated dosing systems universal
(via sciencedaily.com) Original source Automated insulin dosing systems combine low-cost blood-glucose monitors with insulin pumps that use precision dosing to continuously regulate blood-sugar and hold it steady. Synthetic biologists have found a way to piggyback on the technology and make it universally applicable for the precision dosing of virtually any drug.
Published Diverse habitats help salmon weather unpredictable climate changes
(via sciencedaily.com) Original source Restored salmon habitat should resemble financial portfolios, offering fish diverse options for feeding and survival so that they can weather various conditions as the climate changes, a new study shows.
Published Infections from these bacteria are on the rise: New blood test cuts diagnosis time from months to hours
(via sciencedaily.com) Original source Researchers have designed a platform to perform blood-based diagnoses of nontuberculosis mycobacteria, simplifying and shortening a long-complicated procedure from 6 months to 2 hours. Rapid, accurate diagnosis has never been more important as cases of NTM infections have continued to increase annually, spreading from subtropical regions to more temperate zones in part due to global climate change.
Published New study on mating behaviors offers clues into the evolution of attraction
(via sciencedaily.com) Original source In examining the mating rituals of roundworms, researchers uncovered a unique approach to reproduction that maximizes genetic fitness.
Published Information overload is a personal and societal danger
(via sciencedaily.com) Original source We are all aware of the dangers of pollution to our air, water, and earth. In a recently published letter, scientists are advocating for the recognition and mitigation of another type of environmental pollution that poses equivalent personal and societal dangers: information overload.
Published Researchers can reveal illegal timber exports
(via sciencedaily.com) Original source A new method of timber analysis can confidently identify the location in which the tree was harvested. The method has been developed with the aim of combating illegal timber imports from Russia and Belarus.
Published Small amounts of licorice raise blood pressure, study finds
(via sciencedaily.com) Original source It is known that large amounts of licorice cause high blood pressure. A new study now shows that even small amounts of licorice raise blood pressure. The individuals who react most strongly also show signs of strain on the heart.
Published Dog-killing flatworm discovered in Southern California
(via sciencedaily.com) Original source Scientists have confirmed that a potentially fatal dog parasite is present in a portion of the Colorado River that runs through California.
Published Surprising insights about debris flows on Mars
(via sciencedaily.com) Original source The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed by the action of evaporating CO2 ice, according to a new study.
Published It's hearty, it's meaty, it's mold
(via sciencedaily.com) Original source Scientists are exploring how tuning the genomes of mushrooms and molds can transform these food sources into gourmet, nutrient-packed meals made with minimal processing and a light environmental footprint.
Published A healthier diet is linked with a slower pace of aging, reduced dementia risk, study shows
(via sciencedaily.com) Original source A healthier diet is associated with a reduced dementia risk and slower pace of aging, according to a new study. The findings show that a diet-dementia association was at least partially facilitated by multi-system processes of aging. Until now, the biological mechanism of this protection was not well understood.
Published Alzheimer's drug fermented with help from AI and bacteria moves closer to reality
(via sciencedaily.com) Original source Researchers combined artificial intelligence and chemical biosensors to ferment the precursor of an Alzheimer's drug in bacteria.
