Published CRISPR-based genome editing in Nile grass rats
(via sciencedaily.com) Original source A team of researchers has discovered a set of methods that enabled the first successful CRISPR-based genome editing in Nile grass rats.
Published Bioengineers develop lotus leaf-inspired system to advance study of cancer cell clusters
(via sciencedaily.com) Original source Bioengineers have harnessed the lotus effect to develop a system for culturing cancer cell clusters that can shed light on hard-to-study tumor properties. The new zinc oxide-based culturing surface mimics the lotus leaf surface structure, providing a highly tunable platform for the high-throughput generation of three-dimensional nanoscale tumor models.
Published Strength training activates cellular waste disposal
(via sciencedaily.com) Original source The elimination of damaged cell components is essential for the maintenance of the body's tissues and organs. An international research team has made significant findings on mechanisms for the clearing of cellular wastes, showing that strength training activates such mechanisms. The findings could form the basis for new therapies for heart failure and nerve diseases, and even afford benefits for manned space missions.
Published Innovative field experiments shed light on biological clocks in nature
(via sciencedaily.com) Original source A new study has used a series of innovative field experiments to show how plants combine circadian clock signals with environmental cues under naturally fluctuating conditions.
Published Chlamydia can settle in the intestine
(via sciencedaily.com) Original source Chlamydiae are sexually transmitted pathogens that can apparently survive in the human gut for a long time.
Published Colorful traits in primates ease tensions between groups
(via sciencedaily.com) Original source Primate ornamentation plays a crucial role in communication not only within social groups but also between them, according to a new study. The research reveals that the males of species with overlapping home ranges often display vibrant colors or elaborate features, traits that may help reduce intergroup aggression by enabling quick assessments of potential rivals.
Published New gels could protect buildings during wildfires
(via sciencedaily.com) Original source Researchers have developed a sprayable gel that creates a shield to protect buildings from wildfire damage. It lasts longer and is more effective than existing commercial options.
Published Revealing DNA behavior in record time
(via sciencedaily.com) Original source Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process. Biophysicists have developed a technique that speeds up screening of individual DNA molecules at least a thousand times. With this technology, they can measure millions of DNA molecules within a week instead of years to decades.
Published Creature the size of a dust grain found hiding in California's Mono Lake
(via sciencedaily.com) Original source Mono Lake is a beautiful but harsh environment, its salty and arsenic-laced water home to brine shrimp, alkali flies and little else. Scientists recently discovered an unsuspected resident, however, a microscopic creature -- a choanoflagelatte -- that forms colonies that harbor their own unique bacterial microbiomes. The creature, part of the sister group to all animals, could shed light on the evolution of animals' intimate interactions with bacteria and the rise of multicellular life.
Published Engineers design lookalike drug carrier to evade lung's lines of defense
(via sciencedaily.com) Original source Managing hard-to-treat respiratory illnesses like asthma and pulmonary fibrosis just got easier if a new drug-carrying molecule is as sneaky as its inventors think.
Published T cells manipulate the memory of innate immune cells
(via sciencedaily.com) Original source Research reveals that T cells from the adaptive immune system can manipulate the memory of innate immune cells. Previously, it was believed that the memory of innate immune cells operated independently. This surprising connection opens up new possibilities for the treatment of various diseases. A mouse model shows that no immunosuppressive drugs are needed after an organ transplantation if this interaction between T cells and the innate immunity is temporarily blocked after the transplantation.
Published From pets to pests: How domestic rabbits survive the wilderness
(via sciencedaily.com) Original source How do rabbits go from fluffy pets to marauding invaders? Rabbits have colonized countries worldwide, often with dire economic and ecological consequences, but their secret has until now been a mystery. Biologists sequenced the genomes of nearly 300 rabbits from across three continents to unveil the key genetic changes that make these animals master colonizers.
Published Universal flu vaccine candidate protects against infection in mice
(via sciencedaily.com) Original source A new flu vaccine candidate incorporates proteins from 8 strains of influenza.
Published Gut molecule slows fat burning during fasting
(via sciencedaily.com) Original source In a struggle that probably sounds familiar to dieters everywhere, the less a Caenorhabditis elegans (C. elegans) worm eats, the more slowly it loses fat. Now, scientists have discovered why: a small molecule produced by the worms' intestines during fasting travels to the brain to block a fat-burning signal during this time.
Published Next time you beat a virus, thank your microbial ancestors
(via sciencedaily.com) Original source When you get infected with a virus, some of the first weapons your body deploys to fight it were passed down to us from our microbial ancestors billions of years ago. According to new research, two key elements of our innate immune system came from a group of microbes called Asgard archaea.
Published Life from a drop of rain: New research suggests rainwater helped form the first protocell walls
(via sciencedaily.com) Original source New research shows that rainwater could have helped create a meshy wall around protocells 3.8 billion years ago, a critical step in the transition from tiny beads of RNA to every bacterium, plant, animal, and human that ever lived.
Published A deep dive for environmental data on coastal oceans
(via sciencedaily.com) Original source A new study addresses the lack of data on how much human-generated carbon dioxide is present in coastal oceans -- the saltwater ecosystems that link the land and sea. Capturing this data is crucial to calculating how much emissions must be cut in the future.
Published Research shows reducing future global flooding hinges on cutting greenhouse gas emissions
(via sciencedaily.com) Original source Pioneering research forecasts worldwide flooding is likely to be significantly worse in future decades if countries fail to meet official pledges to cut carbon emissions.
Published Eco-friendly cooling device with record-breaking efficiency
(via sciencedaily.com) Original source Researchers have developed an eco-friendly refrigeration device with record-breaking cooling performance in the world, setting to transform industries reliant on cooling and reduce global energy use. With a boost in efficiency of over 48%, the new elastocaloric cooling technology opens a promising avenue for accelerating the commercialization of this disruptive technology and addressing the environmental challenges associated with traditional cooling systems.
Published Survival tactics: AI-driven insights into chromatin changes for winter dormancy in axillary buds
(via sciencedaily.com) Original source Epigenetics confers a survival advantage in plants to endure harsh weather by inducing bud dormancy. Environmental factors or intrinsic signals trigger the transition between growth and dormancy. Researchers explore the role of chromatin and transcriptional changes in the bud and further analyze data using artificial intelligence models. The findings of this study highlight epigenetic strategies to overcome the effects of short winters during global warming for plant survival.
