| Researchers discover solutions to gender bias in autism diagnoses Posted: 23 Jun 2022 09:26 AM PDT A new study demonstrates that an equal number of girls and boys can be identified as having concerns for autism spectrum disorder when screened earlier, correcting large gender differences in current diagnoses. |
| Personal health trackers may include smart face mask, other wearables Posted: 23 Jun 2022 09:26 AM PDT New research demonstrates different ways to improve wearable bioelectronic devices and materials to provide better real-time monitoring of a person's health, including vital signs. |
| Posted: 23 Jun 2022 08:09 AM PDT In a study of more than 107,000 people eligible for cardiac rehabilitation programs, Asian, Black and Hispanic adults were significantly less likely to attend cardiac rehabilitation programs compared to white adults. These differences in cardiac rehabilitation participation were seen at all income levels. The timeframe between hospital discharge and starting cardiac rehabilitation, which can affect recovery and health outcomes, was also at least a week longer among Asian, Black and Hispanic adults compared to white adults. |
| Shedding light on the impact of microplastics on lentil seedling growth Posted: 23 Jun 2022 08:09 AM PDT Microplastic pollution is known to negatively impact seed germination and seedling growth. Although some studies have demonstrated the effects of microplastics on seed germination, the impact of microplastics on the internal biological activity of seeds remained unknown. Now, a group of researchers has used biospeckle optical coherence tomography to reveal that microplastics significantly hinder the internal activity in lentil seeds during germination and can lead to stunted growth at later stages. |
| Are babies the key to the next generation of artificial intelligence? Posted: 23 Jun 2022 08:09 AM PDT Babies can help unlock the next generation of artificial intelligence (AI), according to neuroscientists who have just published new guiding principles for improving AI. The research examines the neuroscience and psychology of infant learning and distills three principles to guide the next generation of AI, which will help overcome the most pressing limitations of machine learning. |
| Hair-raising research: Scientists find surprising link between immune system, hair growth Posted: 23 Jun 2022 08:09 AM PDT Scientists have uncovered an unexpected molecular target of a common treatment for alopecia, a condition in which a person's immune system attacks their own hair follicles, causing hair loss. The findings describe how immune cells called regulatory T cells interact with skin cells using a hormone as a messenger to generate new hair follicles and hair growth. |
| It sucked to be the prey of ancient cephalopods Posted: 23 Jun 2022 08:09 AM PDT The Jurassic cephalopod Vampyronassa rhodanica, thought to be the oldest known ancestor of the modern-day vampire squid (Vampyroteuthis infernalis), was likely an active hunter -- a mode of life that is in contrast with its opportunistic descendant. Scientists came to this conclusion after analyzing microtomographic data of this rare fossil. |
| Modeling a devastating childhood disease on a chip Posted: 23 Jun 2022 08:09 AM PDT Millions of children globally suffer from environmental enteric dysfunction (EED), a chronic inflammatory disease of the intestine that causes malnutrition and stunts their growth. A new Organ Chip models this devastating disease in living human tissue for the first time in vitro. This EED Chip allowed researchers to tease out the complex interplay of genetics and nutrition underpinning the disease, and offers clues for the development of future treatments. |
| Cancer survivors grew to 18 million in the US; more than two-thirds aged 65 years or older Posted: 23 Jun 2022 07:37 AM PDT A new report shows more than 18 million Americans (8.3 million males and 9.7 million females) with a history of cancer were living in the United States as of January 1, 2022, with a little over 12 million (67%) aged 65 years or older. The study also found substantial racial disparities in treatment and survival for common cancers. |
| 'Travel therapy': Could holidays help mental health and wellbeing? Posted: 23 Jun 2022 06:12 AM PDT Many of us will have likely heard of music therapy and art therapy -- but what about 'travel therapy'? A new cross-disciplinary paper proposes we change how we view tourism, seeing it not just as a recreational experience but as an industry that can provide real health benefits. |
| Inside the jellyfish's sting: Exploring the micro-architecture of a cellular weapon Posted: 23 Jun 2022 06:12 AM PDT Summertime beachgoers are all too familiar with the painful reality of a jellyfish sting. But how do the stinging cells of jellyfish and their coral and sea anemone cousins actually work? New research unveils a precise operational model for the stinging organelle of the starlet sea anemone, Nematostella vectensis. The study involved the application of cutting-edge microscopic imaging technologies along with the development of a biophysical model to enable a comprehensive understanding of a mechanism that has remained elusive for over a century. |
