| Solid tumors use a type of T cell as a shield against immune attack Posted: 12 May 2022 06:05 PM PDT Scientists have identified a subset of T cells that show up in great numbers in head and neck tumors, but not in similar tissues of the mouth inflamed by common ailments such as gum disease. |
| Posted: 12 May 2022 01:40 PM PDT A study investigates the reasons for decreasing remission rates for patients with non-Hodgkin lymphoma treated with chimeric antigen receptor-T cell therapy (CAR-T cell therapy). |
| Chemists synthesize psychotropic compound from rainforest tree Posted: 12 May 2022 01:40 PM PDT Scientists found a chemical from a rainforest tree that binds to opioid receptors in the brain and may have utility as an antidepressant or anti-anxiety drug. |
| Jellyfish's stinging cells hold clues to biodiversity Posted: 12 May 2022 11:43 AM PDT The cnidocytes -- or stinging cells -- that are characteristic of sea anemones, hydrae, corals and jellyfish, and make us careful of our feet while wading in the ocean, are also an excellent model for understanding the emergence of new cell types, according to new research. |
| Mind the gap: Space inside eggs steers first few steps of life Posted: 12 May 2022 11:43 AM PDT Imagine sitting at a meeting where the shape of the table and your place at it might impact how you get along with the other members. Cells also communicate with their nearest neighbors, and in embryos, nothing is left to chance in the 'seating plan' for the first few cells. However, questions remain about the how this process is controlled and how it can influence the overall growth of an organism. |
| Bacteria with recording function capture gut health status Posted: 12 May 2022 11:43 AM PDT Researchers have equipped gut bacteria with data logger functionality as a way of monitoring which genes are active in the bacteria. These microorganisms could one day offer a noninvasive means of diagnosing disease or assessing the impact of a diet on health. |
| Massive single-cell atlas across human tissues highlights cell types where disease genes are active Posted: 12 May 2022 11:43 AM PDT Genetic studies have revealed many genes linked to both common and rare disease, but to understand how those genes bring about disease and use those insights to help develop therapies, scientists need to know where they are active in the body. Now researchers have developed a robust experimental pipeline that can profile many more cell types from more tissues than can be studied with other techniques, as well as machine learning methods to put this data together and query the resulting map, or atlas. |
| Posted: 12 May 2022 11:43 AM PDT Researchers have published a review of care for women with pre-eclampsia. |
| Family size may influence cognitive functioning in later life Posted: 12 May 2022 10:41 AM PDT A new study found that having three or more versus two children has a negative effect on late-life cognition. The results further indicated that this effect was strongest in Northern Europe, where higher fertility decreases financial resources but does not improve social resources in this region. |
| Treatment minimizes infants' opioid-related brain abnormalities Posted: 12 May 2022 10:41 AM PDT Researchers have evidence validating the benefits of using medication for opioid use disorder during pregnancy. Brain imaging revealed significant improvements in brain function after treatment. |
| Researchers develop wireless implantable vascular monitoring system Posted: 12 May 2022 09:19 AM PDT Researchers are improving the odds for patients with the development of an implantable soft electronic vascular monitoring system. Their smart stent and printed soft sensors, is capable of wireless real-time monitoring of hemodynamics without batteries or circuits. |
| Excessive sports training may have negative effects on mood Posted: 12 May 2022 09:19 AM PDT New research on road cyclists sheds light on the importance of monitoring a training session load with the use of heart rate variability measuring tools, to favor assimilation and prevent injuries, and to compare training intensity with mood states the following morning. |
| Vaccine for rare but deadly mosquito-borne viruses shows promise in clinical trial Posted: 12 May 2022 09:19 AM PDT A vaccine for eastern equine encephalitis virus (EEEV), western equine encephalitis virus (WEEV), and Venezuelan equine encephalitis virus (VEEV) was found to be safe, well-tolerated and induced a neutralizing antibody response in adult volunteers, according to newly published results from a Phase 1 clinical trial. |
| People choose healthier food when with outsiders for fear of being negatively judged Posted: 12 May 2022 09:18 AM PDT People are more likely to choose a healthy food option than an unhealthy food option among people from different social groups because they fear being judged negatively for their choices. |
| Video games can help boost children's intelligence Posted: 12 May 2022 09:18 AM PDT Scientists have studied how the screen habits of US children correlates with how their cognitive abilities develop over time. They found that the children who spent an above-average time playing video games increased their intelligence more than the average, while TV watching or social media had neither a positive nor a negative effect. |
| Posted: 12 May 2022 09:18 AM PDT New research examines how cavefish, surface-dwelling river fish that flooded into underground cave systems over 100,000 years ago, developed unique metabolic adaptations to survive in nutrient-scarce environments. The study created a genome-wide map of liver tissue for two independent colonies of cavefish along with river fish to understand how cavefish metabolism evolved and how this may be applicable for humans. |
| Huge study of diverse populations advances understanding of type 2 diabetes Posted: 12 May 2022 09:18 AM PDT Genetic epidemiologists have shed important new light on how genes contribute to type 2 diabetes. |
| Breakthrough tech enables seizure localization in minutes Posted: 12 May 2022 09:18 AM PDT New research introduces a novel network analysis technology that uses minimally invasive resting state electrophysiological recordings to localize seizure onset brain regions and predict seizure outcomes in just 10 minutes. |
| 'Nanobodies' from llamas could yield cell-specific medications for humans Posted: 12 May 2022 09:16 AM PDT In 'proof of concept' experiments with mouse and human cells and tissues, researchers say they have designed tiny proteins, called nanobodies, derived from llama antibodies, that could potentially be used to deliver targeted medicines to human muscle cells. |
| Dementia: Combination of 'feelings' and measurements suggest Alzheimer's in the early stage Posted: 12 May 2022 06:27 AM PDT Subjective memory disorders in conjunction with conspicuous levels of beta-amyloid proteins in the cerebrospinal fluid are a strong indication of developing Alzheimer's disease. This is the conclusion of a new study involving about 1,000 older adults. |
