Use of electrical brain stimulation to foster creativity has sweeping implications Posted: 18 Sep 2018 11:08 AM PDT Researchers address neuro-ethical concerns associated with the increasing use of transcranial electrical stimulation (tES). |
Capitalizing on sleep-wake cycle can drastically increase digital ad profits from social media Posted: 18 Sep 2018 10:17 AM PDT New research shows digital content platforms can increase traffic to their websites from social media and boost digital ad profits by at least 8 percent, simply by aligning their posting schedules with target audiences' sleep-wake cycles. |
Nearly half of resident physicians report burnout Posted: 18 Sep 2018 08:09 AM PDT Resident physician burnout in the US is widespread, with the highest rates concentrated in certain specialties, according to research from Mayo Clinic, OHSU and collaborators. |
Class of neurological disorders share 3D genome folding pattern Posted: 18 Sep 2018 08:09 AM PDT Researchers have found a new common thread linking nearly all of the trinucleotide repeat expansion diseases, which include ALS, Huntington's Disease and Fragile X Syndrome, involving the complicated 3D patterns that the DNA is folded into in order to fit in the nucleus of the cell. Nearly all of the short tandem repeats known to grow unstable in disease are located at the boundaries that separate neighboring folded domains. |
Neuroscience of envy: Activated brain region when others are rewarded revealed Posted: 18 Sep 2018 08:09 AM PDT Researchers showed that part of the macaque brain alters the sense of value felt upon receiving a reward in a manner dependent on the receipt of rewards by one's peers. This finding on the neuroscience of envy provides insight into how all primates, including humans, compare their material wellbeing with that of others and are potentially motivated to compete for limited resources. |
Cosmetically smoothing over visible facial scars Posted: 18 Sep 2018 08:09 AM PDT A novel cosmetic product, designed to fill small to moderate facial scars, has shown promise in covering such deformities in a small group of patients. Participants were generally more satisfied with their appearance after the treatment was applied and the researchers believe it could help improve psychological wellbeing for patients whose self-esteem is affected by their scars. |
Is email evil? Bosses are getting boxed in by their inbox Posted: 18 Sep 2018 08:09 AM PDT New research shows that bosses struggle, like the rest of us, to keep up with email demands. What makes managers unique is that email traffic prevents them from being effective leaders and threatens employee performance. |
Exposure to organochlorine pesticides in the womb linked to poorer lung function in childhood Posted: 18 Sep 2018 06:09 AM PDT Babies exposed to higher levels of organochlorine compounds in the womb go on to have worse lung function in childhood, according to new research. These compounds, which include the pesticide DDT, as well as electrical insulators and other industrial products, are now banned in most parts of the world. However, because they degrade very slowly, they are still present in the environment and in foods. |
Enlarged genotype-phenotype correlation for a deletion in neurofibromatosis type 1 Posted: 18 Sep 2018 06:08 AM PDT New research shows that while a three-base pair, in-frame deletion called p.Met992del in the NF1 gene has a mild phenotype for people with the genetic disorder neurofibromatosis type 1, or NF1, the mutation does cause complications. These include non-optic brain tumors, mostly low-grade and asymptomatic, as well as cognitive impairment and/or learning disabilities. |
Hardwired for laziness? Tests show the human brain must work hard to avoid sloth Posted: 18 Sep 2018 06:08 AM PDT Society has encouraged people to be more physically active, yet we are actually becoming less active. This new study offers a possible explanation: Our brains may be innately attracted to sedentary behavior. Electroencephalograms showed that test subjects had to summon extra brain resources when trying to avoid physical inactivity. |
Women who experienced higher levels of trauma gave birth to significantly smaller male babies Posted: 18 Sep 2018 05:21 AM PDT Researchers have found significantly lower birth weights in male infants -- an average decrease of 38 grams, or approximately 1.3 ounces -- born to women who had been exposed to trauma at some point in their lives and who secreted higher levels of cortisol, a hormone related to stress, in late pregnancy. |
Zika vaccine shows promise for treating deadly brain cancer Posted: 18 Sep 2018 05:21 AM PDT Researchers have successfully deployed a Zika virus vaccine to target and kill human glioblastoma brain cancer stem cells, which had been transplanted into mice. In a new study, the team shows that a live, attenuated version of the Zika virus could form the basis of a new treatment option for this fatal brain cancer. |
Do we trust people who speak with an accent? Posted: 18 Sep 2018 05:20 AM PDT A recently published study shows that unless they speak in a confident tone of voice, you're less likely to believe someone who speaks with an accent. And, interestingly, as you make this decision different parts of your brain are activated, depending on whether you perceive the speaker to be from your own 'in-group' or from some type of 'out-group' (e.g., someone with a different linguistic or cultural background). |
Grad students will be future professors, but are they learning how to teach effectively? Posted: 18 Sep 2018 05:20 AM PDT A new study found that graduate students are on board with wanting to adopt interactive teaching methods but often don't get the training or support they need from their institutions to do so. |
Sleep deprived people more likely to have car crashes Posted: 18 Sep 2018 05:20 AM PDT A new study indicates that people who have slept for fewer than seven of the past 24 hours have higher odds of being involved in and responsible for car crashes. The risk is greatest for drivers who have slept fewer than four hours. |
Researchers find children experience concussion symptoms three times longer than adults Posted: 17 Sep 2018 06:09 AM PDT Parents should be aware that significant changes in concussion treatment have emerged in recent years. Primarily, there has been a major shift to promoting active recovery -- including a quick return to social, academic, and athletic activities, as well as specialized rehabilitation. Also important is an understanding that children take three times longer than adults to recover from concussion symptoms -- sometimes even longer due to underlying anxiety or depression issues. |
