| New atlas of genetic function maps complexities of immune system and immune diseases Posted: 29 Apr 2021 11:26 AM PDT A new genetic database for autoimmune and autoinflammatory diseases will allow experts to more deeply understand how immune disorders develop and plan future drug discovery projects. Scientists also hope this atlas of immune-related genome data may eventually be applied to investigations of infectious diseases like COVID-19. |
| Wearable glucose monitors shed light on progression of Type 2 diabetes in Hispanic adults Posted: 29 Apr 2021 09:34 AM PDT Researchers have shown wearable devices that continuously monitor blood sugar provide new insights into the progression of Type 2 diabetes among at-risk Hispanic/Latino adults. |
| Combining solar panels and lamb grazing increases land productivity, study finds Posted: 29 Apr 2021 09:34 AM PDT Land productivity could be greatly increased by combining sheep grazing and solar energy production on the same land, according to new research. |
| High vaccination rate is key to future course of COVID-19 pandemic, computer modeling shows Posted: 29 Apr 2021 09:33 AM PDT Data scientists who developed highly accurate computer modeling to predict trends for COVID-19 cases nationwide have new research that shows how important a high rate of vaccination is to reducing case numbers and controlling the pandemic. |
| Single-cell CRISPR technology deciphers role of chromatin accessibility in cancer Posted: 29 Apr 2021 09:33 AM PDT Researchers have developed CRISPR-sciATAC, a novel integrative genetic screening platform that jointly captures CRISPR gene perturbations and single-cell chromatin accessibility genome-wide. The new method harnesses the programmability of the gene editing system CRISPR to knock-out nearly all chromatin-related genes in parallel, offering researchers deeper insights into the role of DNA accessibility in cancer and in rare diseases involving chromatin. |
| Fasting lowers blood pressure by reshaping the gut microbiota Posted: 29 Apr 2021 09:33 AM PDT For the first time researchers demonstrate that intermittent fasting can reduce hypertension by reshaping the gut microbiota in an animal model. |
| Baby's first stool can help predict risk of developing allergies Posted: 29 Apr 2021 08:24 AM PDT Researchers have shown that the composition of a baby's first feces -- a thick, dark green substance known as meconium -- is associated with whether or not a child will develop allergies within their first year of life. By analyzing meconium samples from 100 infants, they show that the development of a healthy immune system and microbiota may start well before a child is born. |
| A psychologist's guide to donating more effectively to charities Posted: 29 Apr 2021 08:24 AM PDT Donating to a charity is often driven by emotion rather than by calculated assessments based on how to make the biggest impact. A new article looks at how people can be encouraged to direct their charitable contributions in ways that allow them to get more bang for the buck. |
| Many Hispanics died of COVID-19 because of work exposure, study suggests Posted: 29 Apr 2021 07:49 AM PDT Hispanic Americans have died of COVID-19 at a disproportionately high rate compared to whites because of workplace exposure to the virus, a new study suggests. |
| Avocado discovery may point to leukemia treatment Posted: 29 Apr 2021 07:49 AM PDT A compound in avocados may ultimately offer a route to better leukemia treatment, says a new study. |
| How does the brain flexibly process complex information? Posted: 29 Apr 2021 06:52 AM PDT Human decision-making depends on the flexible processing of complex information, but how the brain may adapt processing to momentary task demands has remained unclear. Researchers have now outlined several crucial neural processes revealing that our brain networks may rapidly and flexibly shift from a rhythmic to a 'noisy' state when the need to process information increases. |
| More than 25% of infants not getting common childhood vaccinations Posted: 29 Apr 2021 06:52 AM PDT More than a quarter of American infants in 2018 had not received common childhood vaccines that protect them from illnesses such as polio, tetanus, measles, mumps and chicken pox, new research reveals. |
| Diseases affect brain's networks selectively, BrainMap analysis affirms Posted: 29 Apr 2021 06:52 AM PDT Researchers studied 43 brain disorders and strongly affirmed a theory called the 'network degeneration hypothesis.' This theory holds that disease-related structural damage invades functional networks used in human behavior and often repeats in 'co-alteration networks.' |
| A new strain of a well-known probiotic might offer help for infants' intestinal problems Posted: 29 Apr 2021 06:51 AM PDT A new strain of the Lacticaseibacillus rhamnosus GG probiotic is able to utilise both lactose and casein as well as reproduce in dairy products. The discovery can make it unnecessary to separately add the probiotic to dairy products, in addition to which it could fare better in the intestine, boosting gut health. |
| Risk factors for a severe course of COVID-19 in people with diabetes Posted: 29 Apr 2021 06:51 AM PDT Do all people with diabetes have an increased risk of severe COVID-19, or can specific risk factors also be identified within this group? A new study has focused precisely on this question and gained relevant insights. |
| Expressing variety of emotions earns entrepreneurs funding Posted: 29 Apr 2021 06:03 AM PDT Despite perceptions that entrepreneurs should always be positive about their ventures, a study found that entrepreneurs whose facial expressions moved through a mix of happiness, anger and fear during funding pitches were more successful. Researchers analyzed nearly 500 pitch videos from the online crowdfunding site Kickstarter. Those who varied their emotional expressions had more success on meeting their goal, total amount raised and number of contributors. |
| Team builds better tool for assessing infant brain health Posted: 29 Apr 2021 06:02 AM PDT Researchers have created a new, open-access tool that allows doctors and scientists to evaluate infant brain health by assessing the concentration of various chemical markers, called metabolites, in the brain. The tool compiled data from 140 infants to determine normal ranges for these metabolites. |
| Fish oil supplements and heart rhythm disorder: New analysis Posted: 28 Apr 2021 04:27 PM PDT Omega-3 supplements are associated with an increased likelihood of developing atrial fibrillation in people with high blood lipids, according to a new analysis. |
