Published Fat molecule's inability to bond with shape-shifting protein in cell's powerhouse linked to an inherited metabolic disease
(via sciencedaily.com) Original source By studying mutations in yeast and human cells, scientists say they have found that biochemical bonds between fats and proteins in the mitochondrion, the cell's powerhouse, play a crucial role in how our cells produce energy.
Published Silkworms help grow better organ-like tissues in labs
(via sciencedaily.com) Original source Biomedical engineers have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used in a kidney organ-on-a-chip platform, the membrane helped tissues grow to recreate the functionality of both healthy and diseased kidneys.
Published Determining sex in ants
(via sciencedaily.com) Original source Researchers have been investigating the molecular mechanisms responsible for determining sex in ants. Although the vast majority of an ant colony consists of female workers, males are essential to the continuing survival of the species. In order to uncover the mechanisms involved, the researchers decided to focus on diploid males, which occasionally occur in the Argentine ant.
Published Marsupials key to discovering the origin of heater organs in mammals
(via sciencedaily.com) Original source Around 100 million years ago, a remarkable evolutionary shift allowed placental mammals to diversify and conquer many cold regions of our planet. New research shows that the typical mammalian heater organ, brown fat, evolved exclusively in modern placental mammals. The research team demonstrated that marsupials, our distant relatives, possess a not fully evolved form of brown fat. They discovered that the pivotal heat-producing protein called UCP1 became active after the divergence of placental and marsupial mammals. This finding is crucial for understanding the role of brown fat in mammalian evolution, endothermy, and metabolism.
Published Universal bitter blocker could help patients take their medicines as prescribed
(via sciencedaily.com) Original source Strong bitterness is the main reason why people all over the world, especially children, avoid taking their medicines, putting their health, and sometimes, their lives at risk. Now, a group of scientists has identified the first temporary, universal taste blocker that works in people.
Published Bone loss drugs can help azoles fight fungal infections
(via sciencedaily.com) Original source A new study suggests that adding common bone loss drugs to azoles can improve efficacy when treating fungal infections.
Published New technique reveals how gene transcription is coordinated in cells
(via sciencedaily.com) Original source Researchers invented a technique that allows them to observe which genes and enhancers are active in a cell at the same time. This could help them determine which enhancers control which genes and may reveal potential new drug targets for genetic disorders.
Published Father's diet before conception influences children's health
(via sciencedaily.com) Original source A recent study provides new insights into how fathers' diets and overweight can affect their children's health even before conception. The findings of the study can help develop preventive health measures for men wishing to become fathers: The healthier the father's diet, the lower the risk for their children to develop obesity or diseases such as diabetes later in life.
Published Giant viruses found on Greenland ice sheet
(via sciencedaily.com) Original source Giant viruses found on the Greenland ice sheet probably regulate the growth of snow algae on the ice by infecting them. Knowing how to control these viruses could help us reduce the rate of ice-melt.
Published The embryo assembles itself
(via sciencedaily.com) Original source Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of birds. Interestingly, the mammalian embryo develops similarly. Scientists now introduce a mathematical framework that analyzes self-organization from a single cell to a multicellular organism.
Published Groundbreaking progress in quantum physics: How quantum field theories decay and fission
(via sciencedaily.com) Original source An international research team has sparked interest in the scientific community with results in quantum physics. In their current study, the researchers reinterpret the Higgs mechanism, which gives elementary particles mass and triggers phase transitions, using the concept of 'magnetic quivers.'
Published The coldest lab in New York has new quantum offering
(via sciencedaily.com) Original source Physicists describe the successful creation of a molecular Bose-Einstein condensate (BEC). Made up of dipolar sodium-cesium molecules that were cooled with the help of microwave shielding to just 5 nanoKelvin and lasted for up to two seconds, the new molecular BEC will help scientists explore a number of different quantum phenomena, including new types of superfluidity, and enable the creation of quantum simulators to ecreate the enigmatic properties of complex materials, like solid crystals.
Published Researchers discover 'trojan horse' virus hiding in human parasite
(via sciencedaily.com) Original source An international team has found a new RNA virus that they believe is hitching a ride with a common human parasite. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis disease.
Published Trout in mine-polluted rivers are genetically 'isolated'
(via sciencedaily.com) Original source Trout living in rivers polluted by metal from old mines across the British Isles are genetically 'isolated' from other trout, new research shows.
Published New, modified CRISPR protein can fit inside virus used for gene therapy
(via sciencedaily.com) Original source Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells.
Published The thinnest lens on Earth, enabled by excitons
(via sciencedaily.com) Original source Lenses are used to bend and focus light. Normal lenses rely on their curved shape to achieve this effect, but physicists have made a flat lens of only three atoms thick which relies on quantum effects. This type of lens could be used in future augmented reality glasses.
Published Researchers expose new symbiosis origin theories, identify experimental systems for plant life
(via sciencedaily.com) Original source Research work on symbiosis -- a mutually beneficial relationship between living organisms -- is pushing back against the newer theory of a 'single-origin' of root nodule symbiosis (RNS) -- that all symbiosis between plant root nodules and nitrogen-fixing bacteria stems from one point--instead suggesting a 'multiple-origin' theory of sybiosis which opens a better understanding for genetically engineering crops.
Published Researchers apply quantum computing methods to protein structure prediction
(via sciencedaily.com) Original source Researchers recently published findings that could lay the groundwork for applying quantum computing methods to protein structure prediction.
