| New study examines commuter characteristics and traffic pollution exposure among commuters Posted: 19 Jul 2021 12:35 PM PDT New research examines commuter characteristics to better understand how factors such as departure time, frequency, and commute length are associated with exposure to air pollution. Using personal air pollution monitors, the research clustered commuters to determine whether these clusters were associated with traffic pollution exposures. The study reveals that commuters that travel during rush hour have higher overall exposure to traffic-related air pollution compared to sporadic commuters, though the difference was not statistically significant. |
| Novel autoantibody adds fuel to COVID-19 'firestorm' of inflammation, blood clots Posted: 19 Jul 2021 12:35 PM PDT Researchers have discovered another functional autoantibody in COVID-19 patients that contributes to the disease's development and the 'firestorm' of blood clots and inflammation it induces. The autoantibody makes it much harder for the body to degrade neutrophil extracellular traps, the toxic webs of DNA and proteins produced by overactive immune cells at heightened levels in COVID patients. |

| Why MS patients develop progressive disability Posted: 19 Jul 2021 11:34 AM PDT Did you know multiple sclerosis (MS) means multiple scars? New research shows that the brain and spinal cord scars in people with MS may offer clues to why they developprogressive disability but those with related diseases where the immune system attacks the central nervous system do not. Researchers assessed if inflammation leads to permanent scarring in these three diseases. |
| RNA modification may protect against liver disease Posted: 19 Jul 2021 11:34 AM PDT An RNA modification may offer protection against non-alcoholic fatty liver, a condition that results from a build-up of fat in the liver and can lead to advanced liver disease, according to a new study. The modification may also explain why females tend to have higher fat content in the liver. |
| Living near woodlands is good for children and young people's mental health Posted: 19 Jul 2021 09:03 AM PDT Analysis of children and young people's proximity to woodlands has shown links with better cognitive development and a lower risk of emotional and behavioural problems, in new research that could influence planning decisions in urban areas. |
| Non-neuronal cells drive sex differences in early brain development Posted: 19 Jul 2021 09:03 AM PDT A new study shows that during development, brain cells may find different ways to connect with each other based on sex. |
| Study shows why second dose of COVID-19 vaccine shouldn't be skipped Posted: 19 Jul 2021 09:02 AM PDT The second dose of a COVID-19 vaccine induces a powerful boost to a part of the immune system that provides broad antiviral protection, according to a new study. |
| Researcher's work with flies could be birth control boon Posted: 19 Jul 2021 08:05 AM PDT When it comes to making eggs, female flies and female humans are surprisingly similar. And that could be a boon for women seeking better birth control methods, a researcher reports. |
| Abelacimab effective blood clot treatment, study suggests Posted: 19 Jul 2021 08:05 AM PDT A potentially game-changing treatment for people with, or at risk of, blood clots has been found effective by an international team of researchers. |
| For concussion patients, CTs offer window into recovery Posted: 19 Jul 2021 08:05 AM PDT CT scans for patients with concussion provide critical information about their risk for long-term impairment and potential to make a complete recovery - findings that underscore the need for physician follow-up. |
| Posted: 19 Jul 2021 08:05 AM PDT Some COVID-19 patients who experience acute respiratory failure respond by significantly increasing their respiratory effort -- breathing faster and more deeply. There is concern among some doctors that this level of respiratory effort can lead to further damage to these patients' lungs. Working with intensive care clinicians, engineering researchers have used computational modeling to provide new evidence that high respiratory efforts in COVID-19 patients can produce pressures and strains inside the lung that can result in injury. |
| A small molecule induces readthrough of cystic fibrosis CFTR nonsense mutations Posted: 19 Jul 2021 08:05 AM PDT An experimental drug suggests that a 'path is clearly achievable' to treat currently untreatable cases of cystic fibrosis disease caused by nonsense mutations. This includes about 11 percent of cystic fibrosis patients, as well as patients with other genetic diseases. |
| Firefighters found to have persistent lung damage from Fort McMurray wildfire Posted: 19 Jul 2021 08:05 AM PDT Firefighters at the center of the battle against the massive Fort McMurray, Alberta wildfire in 2016 have persistent lung damage, according to new findings by a occupational health research team. The firefighters had more than double the risk of developing asthma compared with the general population. They also exhibited a number of changes in lung function tests supportive of an effect on the lungs, including greater lung hyperreactivity and increased thickening of the bronchial wall. |
| Novel approach for developing new antibiotics Posted: 19 Jul 2021 08:05 AM PDT Researchers have developed a novel method for producing new antibiotics to combat resistant bacteria. Through an approach that would target bacteria with an antibiotic that is masked by a pro-drug, which the bacteria would themselves remove, the researchers identified a method that would allow for development of new, effective antibiotics that could overcome issues of resistance. |
| Novel coronavirus discovered in British bats Posted: 19 Jul 2021 07:31 AM PDT A coronavirus related to the virus that causes Covid-19 in humans has been found in UK horseshoe bats.
