| Young athletes with history of concussions may have more changes to their brains Posted: 25 Aug 2021 01:36 PM PDT A new study suggests athletes with a history of concussion may show more brain injury from a later concussion, particularly in middle regions of the brain that are more susceptible to damage, when compared to athletes with no history of concussion. |
| Add it up: Could this test equal a way to determine dementia risk? Posted: 25 Aug 2021 01:36 PM PDT People whose scores on a dementia risk test indicated a less brain-healthy lifestyle, including smoking, high blood pressure and a poor diet, may also have the following: lower scores on thinking skills tests, more changes on brain scans and a higher risk of cognitive impairment, according to a new study. |
| New study gives insight into how often COVID-19 spreads through households Posted: 25 Aug 2021 12:37 PM PDT A new study demonstrates how quickly COVID-19 can spread through a household, and provides insight into how and why communities of color have suffered disproportionately from the pandemic. |
| Researchers identify genetic cause of endometriosis and reveal potential drug target Posted: 25 Aug 2021 11:31 AM PDT New research offers insight into how to treat endometriosis. The researchers performed genetic analyses of humans and rhesus macaques to identify a specific gene, NPSR1, that increases risk of suffering from endometriosis. The results reveal a potential new nonhormonal drug target that may lead to improved therapy. |
| Posted: 25 Aug 2021 11:31 AM PDT A Wistar study shows the tumor suppressor Parkin, whose levels are reduced in different cancer types, causes acute metabolic and oxidative stress, suppresses mitochondrial trafficking, and blocks tumor cell movement, reducing primary and metastatic tumor growth. |
| Exposure to tobacco smoke in early life is associated with accelerated biological aging, study finds Posted: 25 Aug 2021 11:31 AM PDT A new study analyzes the association between more than 100 environmental exposures and the 'epigenetic clock' of over 1,000 children in six European countries. |
| New research finds gender differences in fear and risk perception during COVID-19 Posted: 25 Aug 2021 11:30 AM PDT New research suggests that men and women worry about the impact of COVID-19 in far different ways. For example, men are more likely to be concerned about financial consequences from COVID-19 while women report greater fear and more negative expectations about health-related outcomes. |
| A game changer: Virtual reality reduces pain and anxiety in children Posted: 25 Aug 2021 11:30 AM PDT Randomized clinical trial shows that engaging in virtual reality can significantly reduce pain and anxiety in children undergoing intravenous catheter placement. |
| In hot weather, outdoor laborers work less -- when economy is growing Posted: 25 Aug 2021 11:30 AM PDT A new analysis suggests that U.S. workers in industries that expose them to weather conditions work fewer hours per day when temperatures surpass 90 degrees Fahrenheit -- but only during periods of economic growth. |
| Sibling's likelihood of autism diagnosis impacted by age gap, study finds Posted: 25 Aug 2021 08:36 AM PDT Mothers of children with autism who delayed their subsequent pregnancy by 2.5 to three years reduced the likelihood of their next child also being diagnosed on the spectrum, new research shows. |
| Baby detector software embedded in digital camera rivals ECG Posted: 25 Aug 2021 08:36 AM PDT Facial recognition is now common in adults, but researchers have developed software that can reliably detect a premature baby's face in an incubator and remotely monitor its heart and breathing rates - rivaling ECG machines and even outperforming them. This is the first step in using non-contact monitoring in neonatal wards, avoiding skin tearing and potential infections from adhesive pads. |
| 'Nanopore-tal' enables cells to talk to computers Posted: 25 Aug 2021 07:14 AM PDT Researchers have introduced a new class of reporter proteins that can be directly read by a commercially available nanopore sensing device. |
| Why do short-lived lung infections lead to long-lasting lung damage? Posted: 25 Aug 2021 07:14 AM PDT Researchers have found that two populations of stem cells in the lung multiply during and after a viral respiratory infection, sometimes triggering a detrimental remodeling process that can cause persistent lung disease long after the virus has been cleared. |
| Portable MRI provides life-saving information to doctors treating strokes Posted: 25 Aug 2021 05:03 AM PDT When patients exhibit stroke symptoms, doctors must quickly make a life or death determination: Are their symptoms caused by a clot that can be treated with blood thinners or by bleeding in the brain, which may require surgery? A new study shows that a portable MRI device can help identify such intracranial hemorrhages, potentially life-saving information particularly in areas or scenarios where access to sophisticated brain imaging scans are not readily available. |
| Large genetic analysis identifies numerous gene variants linked with differences in food intake Posted: 24 Aug 2021 02:44 PM PDT A team of researchers have identified more than two dozen genetic regions that may affect individuals' food intake. |
| Using your smartwatch to reduce stress Posted: 24 Aug 2021 02:44 PM PDT An engineering researcher has modified a smartwatch to reduce stress. The new technology monitors sweat to infer brain stress and, when detected, sends a message through the smartwatch to calm down. |
| Posted: 24 Aug 2021 10:53 AM PDT New research has confirmed that keeping car windows open to draw in fresh air is key to reducing the risk of contracting the virus in vehicle environments -- but there are trade-offs. |
| Posted: 24 Aug 2021 10:53 AM PDT A new study has shown that the tumor-inhibiting gene TET2 is silenced in a large fraction of cases of acute lymphoblastic leukemia (ALL) in children. The scientists show that the gene can be reactivated by treatment with an existing drug, 5-azacytidine. The results suggest that 5-azacytidine may function as targeted therapy for ALL in children. |
| Scientists discover a fundamental feature of aggressive lymphomas Posted: 24 Aug 2021 10:53 AM PDT New research has revealed a new fundamental feature of aggressive B-cell lymphomas which could open the door to further research into early detection and treatment of the disease. |
| Psychological capital may be the antidote for working in a pandemic, study suggests Posted: 24 Aug 2021 10:53 AM PDT Just like the COVID-19 vaccine protects against contracting the contagious virus, the collective elements of self-efficacy, optimism, hope and resiliency helps inoculate employees from the negative effects of working through a pandemic, according to a new study. |
| Evolutionary ‘arms race’ may help keep cell division honest Posted: 24 Aug 2021 10:53 AM PDT Certain proteins may have evolved to tamp down 'cheating' during meiosis, the cell-division process that gives rise to eggs and sperm. While chromosomes can tip the scales in their favor of winding up in an egg, the team's new work identifies a mechanism that keeps the odds closer to 50-50, possibly reducing the likelihood that chromosomal abnormalities will arise during egg production. |
| Atomic-level imaging of lethal prions provide sharpened focus for potential treatments Posted: 23 Aug 2021 09:58 AM PDT The highest-ever resolution imaging of an infectious prion provides the first atomic-level data of how these abnormal proteins are assembled to cause fatal neurodegenerative diseases in people and animals -- and how they can be potentially targeted by new therapies. |
