Make Or Break For Cellular Tissues Models developed to study liquids are used to investigate the mechanics of cellular tissues, which could further our understanding of embryonic development and cancer In a study about to be published in EPJ E¹, French physicists from the Curie Institute in Paris have demonstrated that the behaviour of a thin layer of cells in contact with an unfavourable substrate is akin...
Genetic Mosaicism Linked To Aging And CancerTwo new studies have linked a condition known as genetic mosaicism to aging and cancer. They suggest presence of the condition, the risk of which increases with age, could be a biomarker for early detection of cancer and other chronic diseases...
PETA Grant Enables Scientists To Guide Chinese Officials In Non-Animal Test UseChinese officials are in the final stages of approving the use of the country's very first non-animal test method for cosmetics ingredients, thanks to guidance from scientists funded by PETA. The 3T3 Neutral Red Uptake Phototoxicity Assay, which tests chemicals for their potential toxicity when they come into contact with sunlight and is already in widespread use in the U.S. and the E.U...
Nanotechnology In Medicine: Huge Potential, But What Are The Risks?Nanotechnology, the manipulation of matter at the atomic and molecular scale to create materials with remarkably varied and new properties, is a rapidly expanding area of research with huge potential in many sectors, ranging from healthcare to construction and electronics...
Evidence Of Darwinian Selection Still Influencing Human EvolutionNew evidence proves humans are continuing to evolve and that significant natural and sexual selection is still taking place in our species in the modern world. Despite advancements in medicine and technology, as well as an increased prevalence of monogamy, research reveals humans are continuing to evolve just like other species...
Shedding Light On Neurodevelopmental DisordersUniversity of Iowa biologists have advanced the knowledge of human neurodevelopmental disorders by finding that a lack of a particular group of cell adhesion molecules in the cerebral cortex - the outermost layer of the brain where language, thought and other higher functions take place - disrupts the formation of neural circuitry...
Genetically Modified Animals For Use In Scientific ResearchResearchers reporting in the journal Cell, a Cell Press publication, have devised a new and improved method for producing genetically modified animals for use in scientific research. The method relies on haploid embryonic stem cells (haESCs) instead of sperm to artificially fertilize immature egg cells...
Morphogen Theory QuestionedNew York University biologists have discovered new mechanisms that control how proteins are expressed in different regions of embryos, while also shedding additional insight into how physical traits are arranged in body plans. Their findings, which appear in the journal Cell, call for reconsideration of a decades-old biological theory...
New Insight Into Molecular Motor MovementMolecular motors are the key to the development of higher forms of life. They transport proteins, signal molecules and even entire chromosomes down long protein fibers, components of the so-called cytoskeleton, from one location in the cell to another...
Developing Organisms Can Identify And Fix Facial DefectsDevelopmental biologists at Tufts University have identified a "self-correcting" mechanism by which developing organisms recognize and repair head and facial abnormalities. This is the first time that such a mechanism has been reported for the face and the first time that this kind of flexible, corrective process has been rigorously analyzed through mathematical modeling...
Antibiotics Kill Bacteria By Damaging Their DNAMIT and Boston University researchers have discovered that while antibiotics attack many parts of bacteria cells, it is the damage they cause to their DNA that inflicts the fatal blow. They write about their findings in a paper published online on 20 April in the journal Science...
