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 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 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 Benefits and downside of fasting
(via sciencedaily.com) Original source Researchers identified a signaling pathway in mice that boosts intestinal stem cells' regeneration abilities after fasting. When cancerous mutations occurred during this regenerative period, mice were more likely to develop early-stage intestinal tumors.
Published Mobile species are 'glue' which connect different habitats together
(via sciencedaily.com) Original source A groundbreaking study conducted across 30 field sites in the southwest UK has revealed the importance of incorporating varied habitats into the landscape at large.
Published Surprising mechanism for removing dead cells identified
(via sciencedaily.com) Original source A tandem signaling process turns ordinary cells into an efficient cleanup crew.
Published Adaptive 3D printing system to pick and place bugs and other organisms
(via sciencedaily.com) Original source A new adaptive 3D printing system can identify the positions of randomly distributed organisms and safely move them to specific locations for assembly.
Published Researchers uncover the secrets of 'plant puberty'
(via sciencedaily.com) Original source Researchers have identified the genetic changes linked to why plants go through a developmental change similar to 'puberty' at different rates, a discovery which could lead to better crop nutrition.
Published Forest loss intensifies climate change by increasing temperatures and cloud level, which leads to decrease of water
(via sciencedaily.com) Original source Researchers report that deforestation during the last two decades induced a higher warming and cloud level rise than that caused by climate change, which threatens biodiversity and water supply in African montane forests.
Published Searching old stem cells that stay young forever
(via sciencedaily.com) Original source The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated by evolutionary highly conserved genes.
Published It's a rave: Underground acoustics amplify soil health
(via sciencedaily.com) Original source Barely audible to human ears, healthy soils produce a cacophony of sounds in many forms -- a bit like an underground rave concert of bubble pops and clicks. Special recordings made by ecologists show this chaotic mixture of soundscapes can be a measure of the diversity of tiny living animals in the soil, which create sounds as they move and interact with their environment.
Published As human activities expand in Antarctica, scientists identify crucial conservation sites
(via sciencedaily.com) Original source Establishing Key Biodiversity Areas in the Southern Ocean will be vital for safeguarding the ecosystem from the impact of human activities, researchers say.
Published Nearly 25% of European landscape could be rewilded, researchers say
(via sciencedaily.com) Original source Europe's abandoned farmlands could find new life through rewilding, a movement to restore ravaged landscapes to their wilderness before human intervention. A quarter of the European continent, 117 million hectares, is primed with rewilding opportunities, researchers report.
Published Zebrafish use surprising strategy to regrow spinal cord
(via sciencedaily.com) Original source A new study maps out a detailed atlas of all the cells involved in regenerating the zebrafish spinal cord. In an unexpected finding, the researchers showed that survival and adaptability of the severed neurons themselves is required for full spinal cord regeneration. Surprisingly, the study showed that stem cells capable of forming new neurons play a complementary role but don t lead the process.
Published Scientists map DNA of Lyme disease bacteria
(via sciencedaily.com) Original source Researchers have produced a genetic analysis of Lyme disease bacteria that may pave the way for improved diagnosis, treatment, and prevention of the tick-borne ailment.
Published Warming waters and nutrient overload: A dangerous combination threatening our rivers and lakes
(via sciencedaily.com) Original source New international research found that food webs are becoming less complex in warmer, nutrient-rich waters.
Published New way inflammation impacts cell communication
(via sciencedaily.com) Original source Researchers have made significant progress in understanding how cells communicate during inflammation.
Published Lake Erie walleye growth is driven by parents' size, experience
(via sciencedaily.com) Original source Parent size and the conditions in which actively spawning adults lived are the most influential factors affecting growth of Lake Erie walleye, a new study has found.
Published Impact of 700 years of Inuvialuit subsistence hunting on beluga whales
(via sciencedaily.com) Original source An international team of researchers analyzed beluga whale bones retrieved from archaeological sites in the Mackenzie Delta, Northwest Territories, Canada, to shed light on the sustainability of centuries of Inuvialuit beluga whale subsistence harvests.
Published Scientists condition crocodiles to avoid killer cane toads
(via sciencedaily.com) Original source Scientists have trialled a new way to protect freshwater crocodiles from deadly invasive cane toads spreading across northern Australia.
