Published New insights into the complex neurochemistry of ants
(via sciencedaily.com) Original source Ants' brains are amazingly sophisticated organs that enable them to coordinate complex behavior patterns such as the organization of colonies. Now, researchers have developed a method that allows them to study ants' brain chemistry and gain insights into the insects' neurobiological processes. The findings could help to explain the evolution of social behavior in the animal kingdom, and shed light on the biochemistry of certain hormone systems that have developed similarly in both ants and humans.
Published Designing synthetic receptors for precise cell control
(via sciencedaily.com) Original source Scientists have developed a groundbreaking new technique for engineering biosensors that respond sensitively to specific biomolecules, enhancing cell migration and targeting in cancer treatment. The findings could lead to more precise control over cellular processes for a wide range of therapeutic applications.
Published Under control to the very end -- how our cells kill themselves
(via sciencedaily.com) Original source Every day, millions of cells die in our body. Other than generally assumed, cells do not simply burst at the end of their lives but rather, a specific protein serves as a breaking point for cell membrane rupture. Researchers have now been able to elucidate the exact mechanism at the atomic level.
Published Microorganisms' climate adaptation can slow down global warming
(via sciencedaily.com) Original source A new study shows that the ability of microorganisms to adapt to climate warming will slow down global warming by storing carbon in soil.
Published You can satisfy your appetite just by looking at pictures of food on your phone
(via sciencedaily.com) Original source Danish experiment reveals: You can satisfy your appetite just by looking at pictures of food on your phone. The results may lead to a new form of treatment for overeating.
Published A guide through the genome
(via sciencedaily.com) Original source Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the differences in genetic information that are responsible for this variation.
Published How plants use sugar to produce roots
(via sciencedaily.com) Original source Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. Botanists have demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein. A better understanding of the processes that regulate root branching at the molecular level could contribute to improving plant growth and therefore crop yields, according to the research team leader.
Published Fossils of a saber-toothed top predator reveal a scramble for dominance leading up to 'the Great Dying'
(via sciencedaily.com) Original source A tiger-sized saber-toothed creature called Inostrancevia has previously only been found in Russia. But scientists have discovered its fossils in South Africa, suggesting that it migrated 7,000 miles across the supercontinent Pangaea during the world's worst mass extinction 252 million years ago. Heading to South Africa allowed it to fill a gap in a faraway ecosystem that had lost its top predators.
Published Corals mark friendly algae for ingestion -- revealing possible conservation target
(via sciencedaily.com) Original source Biologists reveals how coral cells tag friendly algae before ingesting them, initiating a mutually beneficial relationship. This information could guide next-level coral conservation efforts.
Published New supply chain model to empower seabound hydrogen economy
(via sciencedaily.com) Original source A team of researchers has created a new supply chain model which could empower the international hydrogen renewable energy industry.
Published Nitrate: Healthy heart or cancer risk? Meet nutrition's Jekyll and Hyde
(via sciencedaily.com) Original source For a long time nitrate has been viewed warily, with previous research showing it could potentially be linked to causing cancer. However, it has subsequently bee revealed to have various cardiovascular health benefits. So, which is it? A new review of dietary nitrate research shows the answers to its health benefits or risks may lie in where it is sourced from.
Published Demystifying vortex rings in nuclear fusion, supernovae
(via sciencedaily.com) Original source Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source. A mathematical model linking these vortices with more pedestrian types, like smoke rings, could help engineers control their behavior in power generation and more.
Published Puppeteer fungus' targeted takeover of 'zombie' flies
(via sciencedaily.com) Original source Researchers reveal the molecular and cellular underpinnings behind the parasitic fungus, Entomophthora muscae's (E. muscae), ability to manipulate the behavior of fruit flies.
Published Synthetic biology: proteins set vesicles in motion
(via sciencedaily.com) Original source Biophysicists have designed a new cell-like transport system that represents an important milestone on the road to artificial cells.
Published Fossil of mosasaur with bizarre 'screwdriver teeth' found in Morocco
(via sciencedaily.com) Original source Scientists have discovered a new species of mosasaur, a sea-dwelling lizard from the age of the dinosaurs, with strange, ridged teeth unlike those of any known reptile. Along with other recent finds from Africa, it suggests that mosasaurs and other marine reptiles were evolving rapidly up until 66 million years ago, when they were wiped out by an asteroid along with the dinosaurs and around 90% of all species on Earth.
Published Cancer cells use a new fuel in absence of sugar
(via sciencedaily.com) Original source Researchers have discovered a new nutrient source that pancreatic cancer cells use to grow. The molecule, uridine, offers insight into both biochemical processes and possible therapeutic pathways. The findings show that cancer cells can adapt when they don't have access to glucose.
Published Perfect 'pathogen' storm: Vibrio bacteria, Sargassum and plastic marine debris
(via sciencedaily.com) Original source Little is known about the ecological relationship of Vibrio bacteria with Sargassum. Evidence also is sparse as to whether vibrios colonizing plastic marine debris and Sargassum could potentially infect humans. As summer kicks off and efforts are underway to find solutions to repurpose Sargassum, could these substrates pose a triple threat to public health? Results of a study representing the first Vibrio spp. genome assembled from plastic finds Vibrio pathogens have the unique ability to 'stick' to microplastics, harboring potent opportunistic pathogens.
Published Driving on sunshine: Clean, usable liquid fuels made from solar power
(via sciencedaily.com) Original source Researchers have developed a solar-powered technology that converts carbon dioxide and water into liquid fuels that can be added directly to a car's engine as drop-in fuel.
Published Watch these cells rapidly create protrusions for exploration and movement
(via sciencedaily.com) Original source In order to move, cells must be able to rapidly change shape. A team of researchers show that cells achieve this by storing extra 'skin' in folds and bumps on their surface. This cell surface excess can be rapidly deployed to cover temporary protrusions and then folded away for next time.
Published Scales or feathers? It all comes down to a few genes
(via sciencedaily.com) Original source Scales, spines, feathers and hair are examples of vertebrate skin appendages, which constitute a remarkably diverse group of micro-organs. Despite their natural multitude of forms, these appendages share early developmental processes at the embryonic stage. Researchers have discovered how to permanently transform the scales that normally cover the feet of chickens into feathers, by specifically modifying the expression of certain genes.
