| Candy-like models used to make STEM accessible to visually impaired students Posted: 28 May 2021 02:17 PM PDT A breakthrough study aims to make science more accessible to people who are blind or visually impaired through small, candy-like models. |
| New tool activates deep brain neurons by combining ultrasound, genetics Posted: 28 May 2021 12:05 PM PDT A team has developed a new brain stimulation technique using focused ultrasound that is able to turn specific types of neurons in the brain on and off and precisely control motor activity without surgical device implantation. |
| Same difference: Two halves of the hippocampus have different gene activity Posted: 28 May 2021 11:48 AM PDT A study of gene activity in the brain's hippocampus has identified marked differences between the region's anterior and posterior portions. The findings could shed light on a variety of brain disorders that involve the hippocampus and may eventually help lead to new, targeted treatments. |
| Exoskeleton therapy improves mobility, cognition and brain connectivity in people with MS Posted: 28 May 2021 10:34 AM PDT A team of multiple sclerosis (MS) experts led a pilot randomized controlled trial of robotic-exoskeleton assisted exercise rehabilitation (REAER) effects on mobility, cognition, and brain connectivity in people with substantial MS-related disability. Their results showed that REAER is likely an effective intervention, and is a promising therapy for improving the lives of those with MS. |
| Open, expressive family life may reduce social deprivation effects among adopted children Posted: 28 May 2021 08:41 AM PDT An environment in which family members support one another and express their feelings can reduce the effects of social deprivation on cognitive ability and development among adopted children, suggests a small study. In contrast, rule-driven households where family members are in conflict may increase an adopted child's chances for cognitive, behavioral and emotional difficulties. |
| Video platforms normalize exotic pets Posted: 28 May 2021 08:41 AM PDT Researchers are concerned video sharing platforms could be contributing to the normalization of exotic pets and encouraging the exotic pet trade. |
| Tiniest of moments proves key for baby's healthy brain Posted: 28 May 2021 08:41 AM PDT The new findings identify a potential contributor to microcephaly, a birth defect in which the head is underdeveloped and abnormally small. |
| Waking just one hour earlier cuts depression risk by double digits, study finds Posted: 28 May 2021 08:41 AM PDT A genetic study of 840,000 people found that shifting sleep time earlier by just an hour decreases risk of major depression by 23 percent. |
| Japan's hands-off formula in disciplining schoolchildren works. Is it worth a try elsewhere? Posted: 28 May 2021 08:40 AM PDT A look at Japan's mimamoru approach suggests that adults' non-intervention in kids' fights allows children to nurture social and interpersonal skills on their own. Is it worth a try in other countries? |
| Alzheimer's: Blood oxygen levels could explain why memory loss is an early symptom Posted: 28 May 2021 08:40 AM PDT Scientists have recorded blood oxygen levels in the hippocampus and provided experimental proof for why the area, commonly referred to as 'the brain's memory center', is vulnerable to damage and degeneration, a precursor to Alzheimer's disease. |
| Changes in how cholesterol breaks down in the body may accelerate progression of dementia Posted: 27 May 2021 12:01 PM PDT The blood-brain barrier is impermeable to cholesterol, yet high blood cholesterol is associated with increased risk of Alzheimer's disease and vascular dementia. However, the underlying mechanisms mediating this relationship are poorly understood. A new study suggests that disturbances in the conversion of cholesterol to bile acids may play a role in the development of dementia. |
| Hacking and loss of driving skills are major consumer concerns for self-driving cars Posted: 26 May 2021 06:30 AM PDT A new study has revealed the three primary risks and benefits perceived by consumers towards autonomous vehicles (self-driving cars). |
| Serendipitous discovery could lead to treatment for strokes, cardiac arrest Posted: 25 May 2021 01:08 PM PDT Lack of oxygen, which is harmful to the brain, causes hydrogen sulfide 'sewer gas' to accumulate in the brain. The brains of lab animals repeatedly exposed to hydrogen sulfide became tolerant to the gas and lack of oxygen. Researchers identified the mechanism that induces this tolerance, which could lead to new treatments for brain injuries caused by oxygen deprivation. |
| Low blood flow in the brain may be an early sign of Parkinson's disease Posted: 25 May 2021 07:17 AM PDT Patients who suffer from REM sleep behavior disorder have altered blood flow in the brain, which can lead to a lack of oxygen in the brain tissue. In the long term, this may cause symptoms of Parkinson's disease. |
