| Sleep loss does not impact ability to assess emotional information Posted: 11 Oct 2021 06:12 AM PDT It's no secret that going without sleep can affect people's mood, but a new study shows it does not interfere with their ability to evaluate emotional situations. It is often assumed that feeling more negative will color people's experience of emotional images and events in the environment around them. However, researchers found that while going 24 hours without sleep impacted study participants' mood, it did not change their performance on tests evaluating their ability to process emotional words and images. |
| A visit from a social robot improves hospitalized children’s outlook Posted: 09 Oct 2021 06:31 AM PDT A new study finds a visit from human-controlled robot encourages a positive outlook and improves medical interactions for hospitalized children. |
| More severely COVID-19 infected mothers more likely to have preterm birth, study finds Posted: 08 Oct 2021 01:04 PM PDT Researchers have discovered that the more severely infected with COVID-19 a mother is, the more likely she is to experience preterm birth. |
| A rare feat: Material protects against both biological and chemical threats Posted: 08 Oct 2021 01:04 PM PDT Researchers have developed a versatile composite fabric that can deactivate both biological threats, such as the novel coronavirus that causes COVID-19, and chemical threats, such as those used in chemical warfare. A material that is effective against both classes of threats is rare. The new material also is reusable. It can be restored to its original state after the fabric has been exposed to threats by a simple bleach treatment. |
| Excess deaths in people with mental health conditions increased during the COVID-19 pandemic Posted: 08 Oct 2021 08:29 AM PDT The greater number of deaths amongst those with mental health conditions and intellectual disabilities has been amplified during the COVID-19 pandemic, a study based on more than 160,000 patients has revealed. |
| Using indoor air sampling surveillance to sniff out COVID-19 Posted: 08 Oct 2021 07:57 AM PDT A team of scientists and doctors has developed a capability to detect airborne SARS-CoV-2 RNA -- the nucleic acid coding for the virus that causes COVID-19 -- indoors through air sampling. When trialed in two inpatient wards of a major Singaporean hospital caring for active COVID-19 patients the air surveillance approach produced a higher detection rate of environmental SARS-CoV-2 RNA (72%) compared to surface swab samples (9.6 percent) collected in the same area. |
| Stem cell population identified that is key for bone regeneration Posted: 08 Oct 2021 07:57 AM PDT Researchers have identified a subpopulation of mesenchymal stem cells in the bone marrow that express the marker CD73. These cells have a higher potential for proliferation and differentiation, and play a significant role in bone healing, migrating to the site of a fracture and developing into cartilage and bone cells as part of the repair process. These cells have potential for regenerative medicine. |
| Alzheimer's and COVID-19 share a genetic risk factor, study finds Posted: 07 Oct 2021 07:45 PM PDT An anti-viral gene that impacts the risk of both Alzheimer's disease and severe COVID-19 has been identified by researchers. |
| Lung maintains long-term memory of COVID infection Posted: 07 Oct 2021 11:59 AM PDT After infection with the COVID virus, where does the immune system store the memory? A new study finds memory cells take up residence in the lung to protect against reinfection. |
| Non-English-language science could help save biodiversity Posted: 07 Oct 2021 11:58 AM PDT It is commonly assumed that any important scientific knowledge would be available in English, and so scientific knowledge used in international studies is predominantly sourced from English-language documents. But is this assumption correct? According to new research, the answer is no, and science written in languages other than English may hold untapped information crucial to the conservation of global biodiversity. |
| Kids with MIS-C mount normal T cell response to COVID-19, study finds Posted: 07 Oct 2021 09:22 AM PDT A new study suggests multisystem inflammatory syndrome in children (MIS-C), a rare condition associated with COVID-19, is not caused by abnormal T cell response to COVID-19 virus as previously hypothesized. |
| Meditation training reduces long-term stress, hair analysis shows Posted: 07 Oct 2021 09:22 AM PDT A new study finds that mental training reduces the concentration of the stress hormone cortisol in hair.
