| Full-genome CRISPR screen reveals surprising ways neurons survive oxidative stress Posted: 24 May 2021 01:18 PM PDT When a single gene in a cell is turned on or off, its resulting presence or absence can affect the function and survival of the cell. Researchers have now successfully catalogued this effect in the human neuron by separately toggling each of the 20,000 genes in the human genome. |
| Bile acids trigger satiety in the brain Posted: 24 May 2021 01:17 PM PDT Scientists have discovered a new role for bile acids: they curb appetite by entering the brain. Their findings provide new insights into the signals and mechanisms by which satiety is controlled and may have implications for treating obesity. |
| Game on: Game-based program boosts physical activity among diabetes patients Posted: 24 May 2021 01:17 PM PDT Researchers showed that adding gamification with either competition or support increased physical activity for patients with Type 2 diabetes. |
| Step-closer to nasal spray drug delivery for Parkinson's disease Posted: 24 May 2021 01:17 PM PDT Scientists have made significant progress in the development of a nasal spray treatment for patients with Parkinson's disease. |
| Specialized inhibitory cluster gates plasticity in fear learning Posted: 24 May 2021 01:17 PM PDT Researchers have uncovered a new role for a distinct inhibitory cell cluster in the amygdala, acting to dynamically modulate synaptic connections during fear learning. |
| Simple diagnostic tool predicts individual risk of Alzheimer's Posted: 24 May 2021 01:17 PM PDT Researchers at Lund University in Sweden have developed an algorithm that combines data from a simple blood test and brief memory tests, to predict with great accuracy who will develop Alzheimer's disease in the future. The findings are published in Nature Medicine. |
| Analyzing the impact of college gameday homes in the American south Posted: 24 May 2021 08:02 AM PDT Absentee property ownership in many small college football towns has a negative impact on permanent residents of those communities, according to a new study. The research is the first known attempt to quantify and map local geographies of gameday home investments. |
| Study finds women with osteoporosis and low bone density are at increased risk of hearing loss Posted: 24 May 2021 08:02 AM PDT Researchers found that risk of subsequent moderate or worse hearing loss was up to 40 percent higher in study participants with osteoporosis or LBD. |
| Helping adults navigate the decision to move back in with parents Posted: 24 May 2021 08:02 AM PDT A recent study offers insight into how adults can navigate the often awkward experience of moving back in with their parents. |
| Supersensitive connection causes hatred of noises Posted: 24 May 2021 08:01 AM PDT An increased connectivity in the brain between the auditory cortex and the motor control areas related to the face, mouth and throat has been discovered in people with misophonia. Their hatred of 'trigger noises' can lead to an extreme reaction including anger and disgust. This is the first time such a connection in the brain has been identified and it offers a new path for therapies. |
| A natural food supplement may relieve anxiety, study suggests Posted: 24 May 2021 06:20 AM PDT A natural food supplement reduces anxiety in mice, according to a new study. The plant-derived substance, beta-sitosterol, was found to produce this effect both on its own and in synergic combination with an antidepressant. |
| Explanatiion of how religious beliefs may be formed Posted: 24 May 2021 06:20 AM PDT Feeling anxious can direct our attention and memory toward supernatural beings such as gods, a new study has found. |
| Risk of second stroke can be reduced with prevention efforts based on cause of first stroke Posted: 24 May 2021 06:19 AM PDT Having a stroke caused by blocked blood vessels or a transient ischemic attack (TIA) greatly increases your chances of having a future stroke. Identifying the cause or causes of the first stroke is key to developing strategies to prevent additional strokes. Managing blood pressure levels, reducing or quitting smoking, eating a healthy diet, and regular physical activity will reduce the risk of a second stroke, along with managing conditions such as Type 2 diabetes and high cholesterol. |
| Defective gene slows down brain cells Posted: 24 May 2021 06:19 AM PDT Although many forms of autism spectrum disorder (ASD) are thought to have genetic causes, the cellular and molecular functions of the identified genes remain unclear. Scientists studied a high-risk gene and discovered its important role during a critical phase of brain development. |
| Antioxidant protein inside the cell worsens inflammation outside Posted: 20 May 2021 11:53 AM PDT A protein that provides essential protection against free radicals inside the cell provokes damaging inflammation when released outside, activating immune cells and worsening damage following a stroke, according to a new study. |
| Stress from 2016 US presidential election associated with increase in cardiac events Posted: 20 May 2021 10:39 AM PDT A new study shows that exposure to a stressful political election is strongly associated with an increase in potentially life-threatening cardiac events. |
| Children's physical activity linked to academic achievement via regulation of emotions Posted: 19 May 2021 01:36 PM PDT A new study of children in the U.K. suggests that physical activity is linked to emotional regulation in early childhood, which in turn predicts academic achievement. |
