| COVID-19 test offers solution for population-wide testing, scientists say Posted: 01 Jul 2021 04:53 PM PDT Researchers report real-world results on SwabSeq, a high-throughput testing platform that uses sequencing to test thousands of samples at a time to detect COVID-19. They were able to perform more than 80,000 tests in less than two months, with the test showing extremely high sensitivity and specificity. |
| Brain circuit for spirituality? Posted: 01 Jul 2021 04:52 PM PDT Using datasets from neurosurgical patients and those with brain lesions, researchers mapped lesion locations associated with spiritual and religious belief to a specific human brain circuit. |
| Skin in the game: Transformative approach uses the human body to recharge smartwatches Posted: 01 Jul 2021 04:52 PM PDT As smart watches are increasingly able to monitor the vital signs of health, including what's going on when we sleep, a problem has emerged: those wearable, wireless devices are often disconnected from our body overnight, being charged at the bedside. |
| Moderna and Pfizer-BioNTech vaccines prime T cells to fight SARS-CoV-2 variants, study finds Posted: 01 Jul 2021 12:09 PM PDT Researchers have found that T cells from people who have recovered from COVID-19 or received the Moderna or Pfizer-BioNTech vaccines are still able to recognize several concerning SARS-CoV-2 variants. |
| How long can a person live? The 21st century may see a record-breaker Posted: 01 Jul 2021 12:09 PM PDT A new study calculates the probability of living past age 110, which, though rare, likely will increase this century. |
| Study ties milder COVID-19 symptoms to prior run-ins with other coronaviruses Posted: 01 Jul 2021 11:09 AM PDT In COVID-19 patients whose symptoms were mild, researchers found that they were more likely than sicker patients to have signs of prior infection by similar, less virulent coronaviruses. |
| Scientists discover a new class of memory cells for remembering faces Posted: 01 Jul 2021 11:09 AM PDT Our brains have sensory cells, which process the faces that we see, and memory cells dedicated to storing data from person encounters. But until now, a hybrid neuron capable of linking vision to memory -- and explaining how we recall familiar faces -- remained elusive. |
| The key role of astrocytes in cognitive development Posted: 01 Jul 2021 11:09 AM PDT Researchers have now uncovered their crucial role in closing the period of brain plasticity that follows birth, finding them to be key to the development of sensory and cognitive faculties. Over the longer term, these findings will make it possible to envisage new strategies for reintroducing brain plasticity in adults, thereby promoting rehabilitation following brain lesions or neurodevelopmental disorders. |
| COVID-19 aggravates antibiotic misuse in India, study finds Posted: 01 Jul 2021 11:06 AM PDT Antibiotic sales soared during India's first surge of COVID-19, suggesting that the drugs were inappropriately used to treat mild and moderate COVID-19 infections, according to new research. The excessive usage is especially concerning because antibiotic overuse increases the risk for drug-resistant infections -- not just in India, but worldwide. |
| Plastic drapes reduce hypothermia in premature babies Posted: 01 Jul 2021 10:49 AM PDT A researcher is reporting that use of a plastic drape during catheter insertion in very low birth-weight newborn babies can lower the rates of hypothermia, and she is recommending replacing cloth blanket and towels with them. |
| Novel microscopy method provides look into future of cell biology Posted: 01 Jul 2021 10:49 AM PDT What if a microscope allowed us to explore the 3D microcosm of blood vessels, nerves, and cancer cells instantaneously in virtual reality? What if it could provide views from multiple directions in real time without physically moving the specimen and worked up to 100 times faster than current technology? |
| Fibromyalgia likely the result of autoimmune problems Posted: 01 Jul 2021 09:07 AM PDT New research has shown that many of the symptoms in fibromyalgia syndrome (FMS) are caused by antibodies that increase the activity of pain-sensing nerves throughout the body. The results show that fibromyalgia is a disease of the immune system, rather than the currently held view that it originates in the brain. |
| SARS-CoV-2 replication targets nasal ciliated cells early in COVID-19 infection Posted: 01 Jul 2021 09:07 AM PDT The establishment of nasal mucosal immunity against SARS-CoV-2 through a nasal vaccine could be the most efficient way to combat COVID-19 infection. |
| Study identifies risk factors for severe COVID-19 in individuals with sickle cell disease Posted: 01 Jul 2021 09:06 AM PDT New research finds that certain factors, such as a history of severe pain episodes and coexisting organ conditions, increase the risk of severe COVID-19 illness, including hospitalization, in individuals living with sickle cell disease (SCD). According to researchers, the study results underscore the need for COVID-19 risk reduction strategies and vaccination for this medically vulnerable population. |
| Drug dissolved net-like structures in airways of severely ill COVID-19 patients Posted: 01 Jul 2021 08:27 AM PDT When researchers in Sweden performed advanced analyses of sputum from the airways of severely ill COVID-19 patients, they found high levels of neutrophil extracellular traps (NETs). It is already a known fact that NETs can contribute to sputum thickness, severe sepsis-like inflammation and thrombosis. After being treated with an already existing drug, the NETs were dissolved and patients improved. |
| Multitalented filaments in living cells Posted: 01 Jul 2021 08:27 AM PDT Living cells are constantly exposed to a wide variety of mechanical stresses: heart and lungs must withstand expansion and contraction; our skin must be resistant to tearing whilst retaining elasticity; immune cells are squashy so they can move through the body. 'Intermediate filaments' (special protein structures), play an important role here. Researchers have now measured what determines the properties of individual filaments, and which features only occur through the interaction of filaments in networks. |
| How children integrate information Posted: 01 Jul 2021 08:27 AM PDT Researchers use a computer model to explain how children integrate information during word learning. |
| Discovery of nano-sized molecules that might inhibit Alzheimer's and Parkinson's diseases Posted: 01 Jul 2021 08:26 AM PDT Nanosized molecules of a particular chemical element can inhibit the formation of plaque in the brain tissues, according to researchers. The discovery provides renewed hope for novel treatments of, for instance, Alzheimer's and Parkinson's disease in the long run. |
| Study finds 94 percent of patients with cancer respond well to COVID-19 vaccines Posted: 01 Jul 2021 08:26 AM PDT More than 9 of 10 patients with cancer showed good immune response to the COVID-19 mRNA vaccines after receiving both doses, but subsets of high-risk patients did not, according to a new study. |
| Scientists find genetic cause, underlying mechanisms of new neurodevelopmental syndrome Posted: 01 Jul 2021 08:26 AM PDT Scientists have demonstrated that variants in the SPTBN1 gene can alter neuronal architecture, dramatically affecting their function and leading to a rare, newly defined neurodevelopmental syndrome in children. |
| Manufacturing the core engine of cell division Posted: 01 Jul 2021 08:26 AM PDT By modelling the kinetochore from scratch, researchers get a step closer to creating artificial chromosomes. |
| The sense of smell in older adults declines when it comes to meat, but not vanilla, researchers find Posted: 01 Jul 2021 08:26 AM PDT Contrary to what science once suggested, older people with a declining sense of smell do not have comprehensively dampened olfactory ability for odors in general -- it simply depends upon the type of odor. Researchers reached this conclusion after examining a large group of older Danes' and their intensity perception of common food odors. |
| Study with healthcare workers supports that immunity to SARS-CoV-2 is long-lasting Posted: 01 Jul 2021 08:26 AM PDT One year after infection by SARS-CoV-2, most people maintain anti-spike antibodies regardless of the severity of their symptoms, according to a study with healthcare workers. The results suggest that vaccine-generated immunity will also be long-lasting. |
| Extracellular matrix guides growth and function of epithelial cells Posted: 01 Jul 2021 08:26 AM PDT Scientists have found an essential factor from the extracellular matrix that regulates functionality of the breast tissue for instance during pregnancy. |
| Consuming a diet with more fish fats, less vegetable oils can reduce migraine headaches, study finds Posted: 30 Jun 2021 06:30 PM PDT A diet higher in fatty fish helped frequent migraine sufferers reduce their monthly number of headaches and intensity of pain compared to participants on a diet higher in vegetable-based fats and oils, according to a new study. |
| Report sounds alarm on efficacy, safety, ethics of embryo selection with polygenic scores Posted: 30 Jun 2021 02:36 PM PDT A new report raises serious questions about the benefits, risks and ethics of a new service -- which the authors call 'embryo selection based on polygenic scores,' or ESPS -- that allows in vitro fertilization patients to select embryos with the goal of choosing healthier and even smarter children. |
| Study finds changes in wealth tied to changes in cardiovascular health Posted: 30 Jun 2021 08:53 AM PDT A longitudinal study of healthy adults finds upward or downward changes in wealth were associated with respective lower or higher levels of cardiovascular events. |
| Breakthrough for tracking RNA with fluorescence Posted: 30 Jun 2021 08:53 AM PDT Researchers have succeeded in developing a method to label mRNA molecules, and thereby follow, in real time, their path through cells, using a microscope - without affecting their properties or subsequent activity. The breakthrough could be of great importance in facilitating the development of new RNA-based medicines. |
| Thermal imaging offers early alert for chronic wound care Posted: 30 Jun 2021 08:53 AM PDT New method provides information on spatial heat distribution in a wound to accurately predict whether VLUs will heal. The clinical study is the first to investigate textural analysis on VLUs using thermal images that do not require physical contact with the wound. |
| High physical activity levels may counter serious health harms of poor sleep Posted: 29 Jun 2021 04:17 PM PDT Physical activity levels at or above the weekly recommended amounts may counter the serious health harms associated with poor sleep quality, suggests a large long term study. |
| Strategies to speed global vaccine availability Posted: 29 Jun 2021 10:43 AM PDT In a new paper, experts review the vaccine research and development process and propose areas where reforms could increase access, speed time to market and decrease costs -- from research and development, to manufacturing and regulation, to the management of incentives like patents and public funding. |
