| Unraveling the mystery of touch Posted: 11 Oct 2021 08:08 AM PDT Researchers uncover mechanism that underlies the exquisite sensitivity of certain skin surfaces. The analysis, conducted in mice, reveals that the higher sensitivity of certain regions of the skin stems from a greater number of and stronger connections between neurons in these regions and corresponding brain areas that receive signals from them. The findings set the stage for better understanding the mechanisms that underlie abnormalities of touch seen in certain neurodevelopmental disorders in humans. |
| Teaching ancient brains new tricks Posted: 11 Oct 2021 08:08 AM PDT Scientists have found a way to decode the brain activity associated with individual abstract scientific concepts pertaining to matter and energy, such as fermion or dark matter. |
| Precision medicine data dive shows diuretic pill may be viable to test as Alzheimer's treatment Posted: 11 Oct 2021 08:08 AM PDT A commonly available, FDA-approved oral diuretic pill may be a potential candidate for an Alzheimer's disease treatment for those who are at genetic risk, according to new findings. |
| Researchers find warning signs for dementia in the blood Posted: 11 Oct 2021 06:12 AM PDT Researchers have identified molecules in the blood that can indicate impending dementia. Their findings are based on human studies and laboratory experiments. The biomarker is based on measuring levels of so-called microRNAs. According to the study data, microRNAs could potentially also be targets for dementia therapy. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. The amount of cortisol in hair provides information about how much a person is burdened by persistent stress. |
| Posted: 07 Oct 2021 07:10 AM PDT One U.S. child loses a parent or caregiver for every four COVID-19 deaths, a new modeling study reveals. The findings illustrate orphanhood as a hidden and ongoing secondary tragedy caused by the COVID-19 pandemic and emphasizes that identifying and caring for these children throughout their development is a necessary and urgent part of the pandemic response -- both for as long as the pandemic continues, as well as in the post-pandemic era. |
| Internet gaming disorder in college students Posted: 06 Oct 2021 05:05 AM PDT In a study of college students, investigators identified internet gaming disorder in 1.25 percent of participants. Among students who engaged in internet gaming in the past 30 days, 22 percent likely had internet gaming disorder. |
| People with substance use disorders may be at higher risk for SARS-CoV-2 breakthrough infections Posted: 06 Oct 2021 05:05 AM PDT An analysis of electronic health records of nearly 580,000 fully vaccinated people in the United States found that the risk of SARS-CoV-2 breakthrough infection among vaccinated patients with substance use disorders was low overall, but higher than the risk among vaccinated people without substance use disorders. |
