Much of this uncharted territory is thought to code for proteins, and could hold information about what sets humans apart from other animals. The new study paves the way for brand-new research avenues into human health and disease. |
| Long COVID has a significant impact on UK workforce, study finds Posted: 13 Jul 2022 08:46 AM PDT Experts looking at the effects of Long COVID on the UK workforce warn it has had a significant and potentially lasting impact on labor supply. |
| Tiny gene fragments revealed as crucial new players in retinal development and vision Posted: 13 Jul 2022 08:46 AM PDT Researchers have identified a gene that is crucial for the proper development of photoreceptor cells in the retina. The gene works by regulating microexons, tiny fragments of DNA that play an important role in cell function, many of which are found in genes crucial for the cell's ability to transform light into sight. Experimentally knocking the gene out in zebrafish resulted in severely altered photoreceptors with features that closely resemble retinitis pigmentosa in humans. The findings pave the way for new lines of research that uncover the gene's role in unexplained causes of heritable retinal diseases, potentially leading to new therapeutic strategies. |
| Posted: 13 Jul 2022 08:46 AM PDT Individuals with no dementia risk factors, such as smoking, diabetes or hearing loss, have similar brain health as people who are 10 to 20 years younger than them, according to a new study. The study found that a single dementia risk factor could reduce cognition by the equivalent of up to three years of aging. |
| Researchers develop new agent to help root out hypertension-causing tumor Posted: 13 Jul 2022 08:46 AM PDT Researchers have developed a noninvasive method to identify a potential cause of hypertension with a drastic reduction in radiation exposure, a new study shows. The fluorine-based reagent detects whether the hormone aldosterone is being produced abnormally, which is a possible sign of an adrenal adenoma, a tumor that can cause hypertension and can be removed surgically. |
| Turning white blood cells into medicinal microrobots with light Posted: 13 Jul 2022 08:46 AM PDT Medicinal microrobots could help physicians better treat and prevent diseases. But most of these devices are made with synthetic materials that trigger immune responses in vivo. Now, for the first time, researchers have used lasers to precisely control neutrophils -- a type of white blood cell -- as a natural, biocompatible microrobot in living fish. The 'neutrobots' performed multiple tasks, showing they could someday deliver drugs to precise locations in the body. |
| Speeding up the search for the next COVID-19 antiviral Posted: 13 Jul 2022 08:46 AM PDT To develop new COVID-19 medications, researchers are working to target one protein, nsp13, that coronaviruses need to replicate. In a new study, one team describes a new approach to identifying molecules that interfere with this protein -- a step toward development of pan-coronavirus antivirals. |
| Posted: 13 Jul 2022 08:46 AM PDT Researchers have been able to produce antibodies to the SARS-CoV-2 spike protein in hen eggs. Antibodies harvested from eggs might be used to treat COVID-19 or as a preventative measure for people exposed to the disease. |
| Study confirms lead-in-water causes adverse fetal health outcomes Posted: 13 Jul 2022 08:46 AM PDT Health economics researchers have confirmed a causal relationship between lead-in-water and adverse fetal health outcomes. Although many studies have found a correlation between lead exposure and health, a causal link had been lacking in the literature -- until now. |
| Curbing Candida: The cells that keep fungal infections at bay Posted: 13 Jul 2022 08:46 AM PDT Researchers have uncovered a previously unknown defense mechanism employed by the immune system in fighting Candida infections. |
| Urban environments with more vegetation are associated with better health behaviors in children Posted: 13 Jul 2022 08:46 AM PDT Urban areas with more vegetation, higher density of buildings and facilities, lower population density and without major roads are associated with better health behaviors in children, according to new research. |
| Incidental pulmonary embolism on chest CT: AI vs. clinical reports Posted: 13 Jul 2022 08:46 AM PDT An AI tool for detection of incidental pulmonary embolus (iPE) on conventional contrast-enhanced chest CT examinations had high NPV and moderate PPV, even finding some iPEs missed by radiologists. |

| Social development of infants unaffected by COVID-19 pandemic Posted: 13 Jul 2022 08:46 AM PDT Health issues and loss, social isolation and mental health problems -- the pandemic has had a drastic effect on our society. But how have the youngest members of society been coping with these changes? Researchers have found that the presence of parents and caregivers is enough to mitigate the pandemic's negative effects on the social development of infants. |
| New stem cell mechanism in your gut Posted: 13 Jul 2022 08:45 AM PDT Stem cells are a hot topic for creating medical treatments. However, scientists still do not fully understand how they choose to divide or differentiate to renew organs. Researchers have now found a new biophysical mechanism that regulates stem cells in the intestines of mice. There, a stem cell is not purely defined by intrinsic molecular markers but also by their location and movements in their environment. This could have implications for possible new treatments. |
| New study reveals where memory fragments are stored Posted: 13 Jul 2022 08:45 AM PDT While the overall experience is stored in the hippocampus, the brain structure long considered the seat of memory, individual details are parsed and stored elsewhere, in the prefrontal cortex. This separation ensures that, in the future, exposure to any individual cue is sufficient to activate the prefrontal cortex, which then accesses the hippocampus for recall of the whole memory. |
| Maternal milk tied to better school-age outcomes for children born preterm Posted: 13 Jul 2022 08:45 AM PDT In a study that followed preterm infants for seven years, investigators found that children who received greater quantities of maternal milk both during and after time in the neonatal intensive care unit (NICU) had greater academic achievement, higher IQs and reduced ADHD symptoms. |
