| Study: Drivers with shift work sleep disorder 3x more likely to be in crash Posted: 13 May 2021 11:23 AM PDT People who work nontraditional work hours, such as 11 p.m.-7 a.m., or the 'graveyard' shift, are more likely than people with traditional daytime work schedules to develop a chronic medical condition -- shift work sleep disorder -- that disrupts their sleep. According to researchers, people who develop this condition are also three times more likely to be involved in a vehicle accident. |
| New study reveals where memories of familiar places are stored in the brain Posted: 13 May 2021 07:00 AM PDT As we move through the world, what we see is seamlessly integrated with our memory of the broader spatial environment. How does the brain accomplish this feat? A new study reveals that three regions of the brain in the posterior cerebral cortex, which the researchers call 'place-memory areas,' form a link between the brain's perceptual and memory systems. |
| Count your blessings: Short gratitude intervention can increase academic motivation Posted: 13 May 2021 05:49 AM PDT In a recent study, researchers explore how nurturing feelings of gratitude can enhance motivation among college students. Their results show that a keeping a daily gratitude journal for only two weeks has a positive impact on academic motivations that can last months. |
| Academic skills least valued when assessing the 'ideal student' by academics and peers Posted: 12 May 2021 04:45 PM PDT The 'ideal student' - valued by both learners and university staff - is a punctual, organized, hard worker and enthusiastic learner - rather than someone with excellent academic results, high intelligence and good employability. |
| Measuring brain blood flow and activity with light Posted: 12 May 2021 04:45 PM PDT A new, noninvasive method for measuring brain blood flow with light has been developed by biomedical engineers and neurologists and used to detect brain activation. The new method, functional interferometric diffusing wave spectroscopy, or fiDWS, promises to be cheaper than existing technology and could be used for assessing brain injuries, or in neuroscience research. |
| Female lawyers more likely to report stress, risky drinking than male lawyers Posted: 12 May 2021 11:29 AM PDT Work-related factors impact the high rates of stress, risky drinking, and attrition in lawyers differently depending on gender, according to a new study. |
| Genetic risk of heart disease may be due to low Omega 3-linked biomarker Posted: 12 May 2021 11:28 AM PDT People who are genetically more likely to suffer from cardiovascular diseases may benefit from boosting a biomarker found in fish oils, a new study suggests. |
| Ancient Easter Island communities offer insights for successful life in isolation Posted: 12 May 2021 11:28 AM PDT Anthropologists explore how complex community patterns in Easter Island helped the isolated island survive from its settlement in the 12th to 13th century until European contact. |
| New approach to understanding our wellbeing Posted: 12 May 2021 10:29 AM PDT The ability to connect and feel a sense of belonging are basic human needs but new research has examined how these are determined by more than just our personal relationships. Psychologists highlight the importance of taking a wider approach to wellbeing and how it can be influenced by issues such as inequality and anthropogenic climate change. |
| Youths with diverse gender identities bullied up to three times more than peers, study finds Posted: 12 May 2021 10:29 AM PDT Transgender and other youths with diverse gender identities are victimized up to three times more than their peers, according to a new study. |
| Parks not only safe, but essential during the pandemic, study finds Posted: 12 May 2021 08:56 AM PDT Parks played an important role for people seeking respite from the toll of social isolation during the pandemic, and according to new research, they did so without increasing the spread of COVID-19. The study looked at how people used 22 parks in Philadelphia and New York during the height of the pandemic and it found no strong correlation between park use and the number of confirmed cases in surrounding neighborhoods. |
| What does your voice say about you? Posted: 12 May 2021 08:56 AM PDT Everyone has at some point been charmed by the sound of a person's voice: but can we believe our ears? What can a voice really reveal about our character? Now an international research team has shown that people seem to express at least some aspects of their personality with their voice. |
| COVID-19: Discovery of the mechanisms of short- and long-term anosmia Posted: 12 May 2021 08:55 AM PDT Scientists have determined the mechanisms involved in the loss of smell in patients infected with SARS-CoV-2 at different stages of the disease. They discovered that SARS-CoV-2 infects sensory neurons and causes persistent epithelial and olfactory nervous system inflammation. |
| Pandemic screen time tops 6 hours a day for some kindergartners Posted: 12 May 2021 05:34 AM PDT Kindergartners from low-income families spent more than six hours a day in front of screens during two early months of the COVID-19 pandemic, a small Ohio study suggests. That is nearly double the screen time found before the pandemic in similar children, according to other research. |

| Ancestors may have created 'iconic' sounds as bridge to first languages Posted: 12 May 2021 05:34 AM PDT The 'missing link' that helped our ancestors to begin communicating with each other through language may have been iconic sounds, rather than charades-like gestures -- giving rise to the unique human power to coin new words describing the world around us, a new study reveals. |
| COVID-19 alters gray matter volume in the brain, new study shows Posted: 11 May 2021 02:41 PM PDT COVID-19 patients who receive oxygen therapy or experience fever show reduced gray matter volume in the frontal-temporal network of the brain, according to a new study. The study's findings demonstrate changes to the frontal-temporal network could be used as a biomarker to determine the likely prognosis of COVID-19 or evaluate treatment options for the disease. |
| 1.5°C 'degrowth' scenarios suggest need for new mitigation pathways Posted: 11 May 2021 05:12 AM PDT The first comprehensive comparison of 'degrowth' scenarios with established pathways to limit climate change highlights the risk of over-reliance on technological innovation to support continued global growth - which is assumed in established global climate modelling. Findings include: Technologically less risky 'degrowth' limits global warming to 1.5C while global GDP declines by 0.5% annually; a maximum 2C warming can be achieved with 0% GDP growth using available technology (i.e. in line with technological trends). |
| Study shows how our brains sync hearing with vision Posted: 11 May 2021 05:11 AM PDT The brain alters our sense of time to synchronize our joint perception of sound and vision.
