| Muscle biopsy test for biomarker could lead to earlier diagnosis of ALS Posted: 21 Jun 2022 03:45 PM PDT Amyotrophic lateral sclerosis (ALS) is a progressive disease of the nervous system. It affects nerve cells in the brain and spinal cord called motor neurons. Motor neurons control muscle movement and ALS causes them to deteriorate and eventually die. The motor neurons lose the ability to send messages to the muscles in the body, affecting voluntary muscle movements. There have been recent advances in treating ALS, but current treatments can only slow disease progression. That is why it is important to diagnose ALS as early as possible. |
| Plant virus plus immune cell-activating antibody clear colon cancer in mice, prevent recurrence Posted: 21 Jun 2022 03:44 PM PDT A new combination therapy to combat cancer could one day consist of a plant virus and an antibody that activates the immune system's 'natural killer' cells, shows a new study. In mouse models of colon cancer, the combination therapy eliminated all tumors and prevented their recurrence, which in turn resulted in 100% survival. The therapy also increased survival in mouse models of melanoma. |
| How the brain interprets motion while in motion Posted: 21 Jun 2022 12:51 PM PDT New research provides insights into a neural mechanism involved in how the brain interprets sensory information. The research may have applications for treating brain disorders and designing artificial intelligence. |
| Posted: 21 Jun 2022 12:51 PM PDT Scientists have discovered 15 additional genetic mutations in the KCNK9 gene that cause a neurodevelopmental syndrome. Symptoms of the disorder range from speech and motor impairment to behavioral abnormalities, intellectual disability and distinctive facial features. |
| Relationships are best between people of similar desirability, study finds Posted: 21 Jun 2022 12:51 PM PDT New research found that not only are people who are similarly desirable more likely to enter into a relationship, but they are also more likely to experience success within that relationship. |
| 75% of teens aren't getting recommended daily exercise Posted: 21 Jun 2022 11:18 AM PDT Three out of every four teens aren't getting enough exercise, and this lack is even more pronounced among female students. But new research suggests improving a school's climate can increase physical activity among adolescents. |
| Study reveals smaller-than-expected percentage of research in psychology is truly multidisciplinary Posted: 21 Jun 2022 11:18 AM PDT Researchers examined scholarly articles for the years 2008-18 classified as 'Psychology, Multidisciplinary,' finding just 25% of citations referenced research published in fields outside psychology. |
| How tumors make immune cells 'go bad' Posted: 21 Jun 2022 11:18 AM PDT Investigators have discovered that cancerous tumors called soft-tissue sarcomas produce a protein that switches immune cells from tumor-attacking to tumor-promoting. The study could lead to improved treatments for soft-tissue sarcomas. |
| Pacific whiting skin has anti-aging properties that prevent wrinkles, research suggests Posted: 21 Jun 2022 11:18 AM PDT The gelatin in the skin of Pacific whiting, an abundant fish on the Pacific Coast of North America, may help prevent skin wrinkling caused by ultraviolet radiation, a new study found. |
| New safe-sleep guidelines aim to reduce infant deaths Posted: 21 Jun 2022 11:18 AM PDT There are 3,500 sleep-related infant deaths in the United States each year. Many of those deaths are preventable, and the authors of the new guidelines are urging parents to take simple steps to help keep their children safe. |
| Children who had bronchitis linked to adult lung problem Posted: 21 Jun 2022 11:18 AM PDT Study into the consequences of childhood infection finds Australian children who had bronchitis at least once before the age of seven were more likely to have lung problems in later life. |
| COVID-19 rebound after taking Paxlovid likely due to insufficient drug exposure, study finds Posted: 21 Jun 2022 11:17 AM PDT COVID-19 rebound following Paxlovid treatment likely due to insufficient drug exposure, researchers find after showing rebound patient did not show drug resistance or impaired immunity. |
| Walking gives the brain a 'step-up' in function for some Posted: 21 Jun 2022 11:17 AM PDT It has long been thought that when walking is combined with a task -- both suffer. Researchers have now found that this is not always the case. Some young and healthy people improve performance on cognitive tasks while walking by changing the use of neural resources. |
| SeqScreen can reveal 'concerning' DNA Posted: 21 Jun 2022 11:17 AM PDT Computer scientists have developed a program to screen short DNA sequences, whether synthetic or natural, to determine their toxicity. |
| Genetic mutations enable efficient evolution of TB-causing bacteria Posted: 21 Jun 2022 08:47 AM PDT Researchers have identified how the bacterium that causes tuberculosis (TB) can evolve rapidly in response to new environments. |
| High vaccination rates blunted Delta variant surge in some US states Posted: 21 Jun 2022 08:47 AM PDT A joint modelling initiative by nine teams predicted the U.S. surge of COVID-19 caused by the Delta variant of the SARS-CoV-2 virus in the summer of 2021, and found vaccination uptake to be critical to limiting transmission. |
| Vitamins, supplements are a 'waste of money' for most Americans Posted: 21 Jun 2022 08:47 AM PDT Scientists say for non-pregnant, otherwise healthy Americans, vitamins are a waste of money because there isn't enough evidence they help prevent cardiovascular disease or cancer. They've written an editorial in support of new recommendations that state there was 'insufficient evidence' that taking multivitamins, paired supplements or single supplements can help prevent cardiovascular disease and cancer in otherwise healthy, non-pregnant adults. |
| Global AFib study finds simple ablation has best outcomes Posted: 21 Jun 2022 08:47 AM PDT Results from one of the largest global studies of atrial fibrillation (AFib) procedures show that the simple approach is usually best when it comes to ablation, a procedure where physicians destroy or ablate cardiac tissue to correct irregular heart rhythms. Researchers found that using advanced image-guided technology to more aggressively target diseased areas of the heart that cause arrythmias didn't lead to better outcomes for patients -- and put some at higher risk of strokes, according to new results. |
| Posted: 21 Jun 2022 06:14 AM PDT A new study reveals that females are 'significantly' more likely to suffer from Long COVID than males and will experience substantially different symptoms. |
| Agriculture emissions pose risks to health and climate Posted: 21 Jun 2022 06:14 AM PDT Environmental engineers determine the economic cost of reactive nitrogen emissions from agriculture, and their significant risks to populations through air pollution and climate change. |
| Vital cell machinery behind the human body's incorporation of selenium observed Posted: 20 Jun 2022 05:49 PM PDT Scientists have determined the process for incorporating selenium -- an essential trace mineral found in soil, water and some foods that increases antioxidant effects in the body -- to 25 specialized proteins, a discovery that could help develop new therapies to treat a multitude of diseases from cancer to diabetes. |
| Posted: 20 Jun 2022 05:49 PM PDT Some people who experience heart failure have less biodiversity in their gut or have elevated gut metabolites, both of which are associated with more hospital visits and greater risk of death, according to a systematic review of research. |
| Who benefits from brain training and why? Posted: 20 Jun 2022 09:23 AM PDT If you are skilled at playing puzzles on your smartphone or tablet, what does it say about how fast you learn new puzzles, or, more broadly, how well you can focus, say, in school or at work? Or, in the language of psychologists, does 'near transfer' predict 'far transfer'? A team of psychologists has found that people who show near transfer are more likely to show far transfer. |
