Climate: Uncertainty in scientific predictions can help and harm credibility Posted: 18 Oct 2019 08:21 AM PDT The ways climate scientists explain their predictions about the impact of global warming can either promote or limit their persuasiveness. |
Easy at-home assessment of teeth grinding in sleep Posted: 18 Oct 2019 08:21 AM PDT An easy-to-use electrode set can assess sleep bruxism severity as well as a conventional polysomnography, a new study shows. |
A compound effective to chemotherapy-resistant cancer cells identified Posted: 18 Oct 2019 06:12 AM PDT A compound effective in killing chemotherapy-resistant glioblastoma-initiating cells (GICs) has been identified, raising hopes of producing drugs capable of eradicating refractory tumors with low toxicity. |
Posted: 17 Oct 2019 06:16 PM PDT Non-invasive brain stimulation is to be trialled for the first time alongside advanced brain imaging techniques in patients who are minimally conscious or in a vegetative state. |
Health care intervention: Treating high-need, high-cost patients Posted: 17 Oct 2019 02:01 PM PDT Patients with complex needs -- serious mental and physical health problems and substance use disorders -- flock to emergency rooms costing the health care system billions every year. A new study suggests a nontraditional approach to these patients can significantly improve their daily functioning and health outcomes. |
Research gauges neurodegeneration tied to FXTAS by measuring motor behavior Posted: 17 Oct 2019 11:28 AM PDT Researchers used a grip-force test to analyze sensorimotor function in people with the FMR1 premutation, with the aim of determining FXTAS risk and severity. |
Male and female mice have different brain cells Posted: 17 Oct 2019 11:28 AM PDT Scientists discover that a brain region known to control sex and violence contains rare cell types that differ in male versus female mice. |
Fundamental insight into how memory changes with age Posted: 17 Oct 2019 11:11 AM PDT New research could help explain why memory in old age is much less flexible than in young adulthood. Through experiments in mice the researchers discovered that there were dramatic differences in how memories were stored in old age, compared to young adulthood. |
Targeted therapy to help children with deadly nerve cancer Posted: 17 Oct 2019 11:11 AM PDT Researchers have identified a targeted therapy for adolescent patients with neuroblastoma, a deadly pediatric nerve cancer, who would otherwise have no treatment options, according to a new study. |
BARseq builds a better brain map Posted: 17 Oct 2019 11:10 AM PDT A brain mapping technique called BARseq is capable of mapping thousands of neurons in a single mouse, at single neuron resolution, while also detailing which neuron expresses what genes. It could be a game-changer for how neuroscientists look at brains. |
Assigning workers to new networks boosts sustainability Posted: 17 Oct 2019 10:14 AM PDT Innovation comes from people in different units who have new knowledge, and a new study about conservation organizations suggests encouraging employees to think and act outside network boxes from time to time. |
Near misses on slot machines may not encourage continued gambling Posted: 17 Oct 2019 09:52 AM PDT For nearly 70 years, researchers believed that near-miss events like these would encourage you to continue gambling. But new research suggests that the near-miss effect may not exist at all. |
Evidence of behavioral, biological similarities between compulsive overeating and addiction Posted: 17 Oct 2019 09:52 AM PDT Does yo-yo dieting drive compulsive eating? There may be a connection. According to researchers the chronic cyclic pattern of overeating followed by undereating, reduces the brain's ability to feel reward and may drive compulsive eating. This finding suggests that future research into treatment of compulsive eating behavior should focus on rebalancing the mesolimbic dopamine system -- the part of the brain responsible for feeling reward or pleasure. |
Embryo's early development revealed in a dish Posted: 17 Oct 2019 09:51 AM PDT Bioscientists develop a method to observe patterns of early embryonic development, during which ectodermal cells diverge toward their fates as skin, organs and the nervous system. |
Bad break-ups may not trigger weight gain from emotional eating Posted: 17 Oct 2019 09:19 AM PDT That pint of ice cream after a nasty breakup may not do as much damage as you think. Despite the emotional turmoil, people on average do not report gaining weight after a relationship dissolution, according to new research. |
Image analysis to automatically quantify gender bias in movies Posted: 17 Oct 2019 08:17 AM PDT Many commercial films worldwide continue to express womanhood in a stereotypical manner, a recent study using image analysis showed. A research team developed a novel image analysis method for automatically quantifying the degree of gender bias in in films. |
Mothers' behavior influences bonding hormone oxytocin in babies Posted: 17 Oct 2019 08:17 AM PDT A new epigenetic study now suggests that mothers' behavior can also have a substantial impact on their children's developing oxytocin systems. |
Cultivating joy through mindfulness: An antidote to opioid misuse, the disease of despair Posted: 17 Oct 2019 08:17 AM PDT New research shows that a specific mind-body therapy, Mindfulness-Oriented Recovery Enhancement (MORE), increases the brain's response to natural, healthy rewards while also decreasing the brain's response to opioid-related cues. |
Daily exposure to blue light may accelerate aging, even if it doesn't reach your eyes Posted: 17 Oct 2019 07:12 AM PDT Prolonged exposure to blue light, such as that which emanates from your phone, computer and household fixtures, could be affecting your longevity, even if it's not shining in your eyes. New research suggests that the blue wavelengths produced by light-emitting diodes damage cells in the brain as well as retinas, according to a new study in a model organism. |
Treatment of metabolic dysfunction could be a potential therapy for Alzheimer's disease Posted: 17 Oct 2019 07:12 AM PDT A team of researchers has found evidence that metabolic dysfunction is a primary cause of Alzheimer's disease. |
Do we trust artificial intelligence agents to mediate conflict? Not entirely Posted: 16 Oct 2019 06:49 AM PDT We may listen to facts from Siri or Alexa, or directions from Google Maps or Waze, but would we let a virtual agent enabled by artificial intelligence help mediate conflict among team members? A new study says not just yet. |
