| The Equalizer: An engineered circuit for uniform gene expression Posted: 12 Jul 2021 10:01 AM PDT Researchers deloped a new genetic circuit called the Equalizer that leads to uniform gene expression. |
| Artificial intelligence could be new blueprint for precision drug discovery Posted: 12 Jul 2021 10:01 AM PDT Researchers have described a new approach that uses machine learning to hunt for disease targets and then predicts whether a drug is likely to receive FDA approval. |
| MaxDIA: Taking proteomics to the next level Posted: 12 Jul 2021 09:22 AM PDT A new software improves data-independent acquisition proteomics by providing a computational workflow that permits highly sensitive and accurate data analysis. |
| Novel screening approach improves diagnosis of metabolic disorders in newborns Posted: 12 Jul 2021 09:22 AM PDT A screening method known as untargeted metabolomics profiling can improve the diagnostic rate for inborn errors of metabolism, a group of rare genetic conditions, by about seven-fold when compared to the traditional metabolic screening approach. |
| 'Clock' created to predict immunological health and chronic diseases of aging Posted: 12 Jul 2021 09:21 AM PDT Researchers have created an inflammatory clock of aging (iAge) which measures inflammatory load and predicts multi-morbidity, frailty, immune health, cardiovascular aging and is also associated with exceptional longevity in centenarians. |
| A fermented-food diet increases microbiome diversity and lowers inflammation, study finds Posted: 12 Jul 2021 09:21 AM PDT A diet rich in fermented foods enhances the diversity of gut microbes and decreases molecular signs of inflammation, according to researchers. |
| Technology that restores the sense of touch in nerves damaged as a result of injury Posted: 12 Jul 2021 09:21 AM PDT Researchers have developed a sensor that can be implanted anywhere in the body -- for example, under the tip of a severed finger. The sensor connects to another nerve that functions properly and restores tactile sensation to the injured nerve. The development is biocompatible and does not require electricity, wires, or batteries. |
| Human environmental genome recovered in the absence of skeletal remains Posted: 12 Jul 2021 09:21 AM PDT Ancient sediments from caves have already proven to preserve DNA for thousands of years. The amount of recovered sequences from environmental sediments, however, is generally low, which complicates analyses. A study has now successfully retrieved three mammalian environmental genomes from a single soil sample of 25,000 years BP obtained from the cave of Satsurblia in the Caucasus (Georgia). |
| Mathematicians develop ground-breaking modeling toolkit to predict local COVID-19 impact Posted: 12 Jul 2021 09:21 AM PDT Mathematicians have created a new modeling toolkit which predicts the impact of COVID-19 at a local level with unprecedented accuracy. |
| Preferred life expectancy and its association with hypothetical adverse life scenarios Posted: 12 Jul 2021 09:21 AM PDT A new study sheds light on how the specter of dementia and chronic pain reduce people's desire to live into older ages. Among Norwegians 60 years of age and older the desire to live into advanced ages was significantly reduced by hypothetical adverse life scenarios with the strongest effect caused by dementia and chronic pain. |
| People given 'friendly' bacteria in nose drops protected against meningitis, study suggests Posted: 12 Jul 2021 09:21 AM PDT A recent trial has shown that nose drops of modified 'friendly' bacteria may protect against meningitis. |
| Sensing 'junk' RNA after chemotherapy enhances blood regeneration Posted: 12 Jul 2021 09:21 AM PDT Scientists reveal that during hematopoietic regeneration, RNA expressed from a part of the genome considered 'junk DNA' is used by hematopoietic stem cells to get activated and proliferate. The study shows that these so-called transposable elements make RNA after chemotherapy and activate an immune receptor which induces inflammatory signals enhancing hematopoietic stem cell cycling and thus participating in the regeneration of the hematopoietic system. |
| Training helps teachers anticipate how students with learning disabilities might solve problems Posted: 12 Jul 2021 09:20 AM PDT Researchers found that a four-week training course made a substantial difference in helping special education teachers anticipate different ways students with learning disabilities might solve math problems. |
| Every spot of green space counts Posted: 12 Jul 2021 07:22 AM PDT An international study of parks and gardens finds even the humble roadside verge plays an important role in the environment and for our health. |
| Remarkable new insights into the pathology of Usher syndrome Posted: 12 Jul 2021 07:22 AM PDT Human Usher syndrome is the most common form of hereditary deaf-blindness. Researchers have now identified a novel pathomechanism leading to Usher syndrome. They have discovered that the Usher syndrome type 1G protein SANS plays a crucial role in regulating splicing process. Furthermore, they have been able to demonstrate that defects in the SANS protein can lead to errors in the splicing of genes related to the Usher syndrome, which may provoke the disease. |
| A step toward advancing precision hormone therapies to reduce Alzheimer's risk Posted: 12 Jul 2021 06:22 AM PDT When it comes to post-menopausal hormone therapy, the type, route and duration all play a role in reducing the risk of neurodegenerative diseases. |
| Innovative gene therapy 'reprograms' cells to reverse neurological deficiencies Posted: 12 Jul 2021 06:22 AM PDT A novel method of gene therapy is helping children born with a rare genetic disorder called AADC deficiency that causes severe physical and developmental disabilities. The study offers new hope to those living with incurable genetic and neurodegenerative diseases. |
| Scientists blueprint bacterial enzyme believed to 'stealthily' suppress immune response Posted: 12 Jul 2021 06:22 AM PDT Scientists have produced the first fine-detail molecular blueprints of a bacterial enzyme known as Lit, which is suspected to play a 'stealthy' role in the progression of infection by reducing the immune response. Blueprints such as these allow drug designers to uncover potential weaknesses in bacterial arsenals as they seek to develop new therapeutics that may help us win the war against antibiotic resistance. |
| A Trojan horse could help get drugs past our brain's tough border patrol Posted: 12 Jul 2021 06:22 AM PDT The blood-brain barrier protects the brain and is notoriously hard to get past for drug delivery, making it difficult to treat disorders in the central nervous system. In a mice study, a team of researchers used a novel approach to study the barrier and in detail characterized a Trojan horse technique to help to solve the challenge. |
