Neuroscientists use flashes of light to both ‘read’ and ‘write’ brain signals UCL researchers have developed an innovative way to understand how the brain works by using flashes of light, allowing them to both ‘read’ and ‘write’ brain signals. The new technique, described in Nature Methods, combines two cutting-edge technologies for reading and writing electrical activity in the brain. First, genetically encoded activity sensors enable neuroscientists to [...]The post Neuroscientists use flashes of light to both ‘read’ and ‘write’ brain signals appeared first on PsyPost.

Diverse autism mutations lead to different disease outcomes People with autism have a wide range of symptoms, with no two people sharing the exact type and severity of behaviors. Now a large-scale analysis of hundreds of patients and nearly 1000 genes has started to uncover how diversity among traits can be traced to differences in patients’ genetic mutations. The study, conducted by researchers [...]The post Diverse autism mutations lead to different disease outcomes appeared first on PsyPost.
Limit imaging scans for headache? Neurosurgeons raise concerns Recent guidelines seeking to reduce the use of neuroimaging tests for patients with headaches run the risk of missing or delaying the diagnosis of brain tumors, according to a special article in the January issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part [...]The post Limit imaging scans for headache? Neurosurgeons raise concerns appeared first on PsyPost.
Study links suicide risk with insomnia, alcohol use A new study is the first to show that insomnia symptoms mediate the relationship between alcohol use and suicide risk, and that this mediation is moderated by gender. The study suggests that the targeted assessment and treatment of specific sleep problems may reduce the risk of suicide among those who use alcohol. The study found [...]The post Study links suicide risk with insomnia, alcohol use appeared first on PsyPost.
Fear of terrorism increases resting heart rate and risk of death A new study of over 17,000 Israelis has found that long-term exposure to the threat of terrorism can elevate people’s resting heart rates and increase their risk of dying. This is the first statistics-based study, and the largest of its kind, which indicates that fear induced by consistent exposure to the threat of terror can [...]The post Fear of terrorism increases resting heart rate and risk of death appeared first on PsyPost.
An existing drug, riluzole, may prevent foggy ‘old age’ brain Forgetfulness, it turns out, is all in the head. Scientists have shown fading memory and clouding judgment, the type that comes with advancing age, show up as lost and altered connections between neurons in the brain. But new experiments suggest an existing drug, known as riluzole and already on the market as a treatment for [...]The post An existing drug, riluzole, may prevent foggy ‘old age’ brain appeared first on PsyPost.
Inspired By Women Warriors Woman warriors are those who inspire others to become the best they can become. They are pathfinders and those who pave the way for the rest of us navigating our own journey. They are powerful women who we all talk about and aspire to be. At year end, it is a good time to think of all the warriors in our lives.
Three Things I Learned About Happiness from Living With   It’s so easy to get wrapped up during the Holidays. The malls are packed with people all buying, buying, buying. We rack our brains for what is the best present for the kid/uncle/mother/father who has everything and can’t possibly need anything more. And we are encouraged — toys, games,...
Hoping They’ll Change Doesn’t Make It So Ever gotten involved with someone, while hoping they’ll change? Of course no one you choose will be perfect (my husband, Jake, objects to that statement). And we don’t want to be too picky. We can have too many personal desires and quirks that we want satisfied by our partner. But...
Light-emitting e-readers before bedtime can adversely impact sleep Use of a light-emitting electronic device (LE-eBook) in the hours before bedtime can adversely impact overall health, alertness, and the circadian clock which synchronizes the daily rhythm of sleep to external environmental time cues, according to researchers at Brigham and Women’s Hospital (BWH) who compared the biological effects of reading an LE-eBook compared to a [...]The post Light-emitting e-readers before bedtime can adversely impact sleep appeared first on PsyPost.
New cell marking technique to help understand how our brain works Scientists from the University of Southampton have developed a new technique to mark individual brain cells to help improve our understanding of how the brain works. In neuroscience research, it is a challenge to individually label cells and to track them over space or time. Our brain has billions of cells and to be able [...]The post New cell marking technique to help understand how our brain works appeared first on PsyPost.
Crowdsourcing with mobile apps brings ‘big data’ to psychological research A fast-paced game app where players pretend they are baggage screening officers operating airport x-ray scanners has provided researchers with billions of pieces of data in record time, according to an article published by the American Psychological Association. “Mobile devices offer researchers an exciting new means to crowdsource an experiment using games that are actually [...]The post Crowdsourcing with mobile apps brings ‘big data’ to psychological research appeared first on PsyPost.
New non-invasive method can detect Alzheimer’s disease early No methods currently exist for the early detection of Alzheimer’s disease, which affects one out of nine people over the age of 65. Now, an interdisciplinary team of Northwestern University scientists and engineers has developed a noninvasive MRI approach that can detect the disease in a living animal. And it can do so at the [...]The post New non-invasive method can detect Alzheimer’s disease early appeared first on PsyPost.
Study links physical violence to stress hormone in women but not men A new study links physical violence against women by male partners to a disruption of a key steroid hormone that opens the door potentially to a variety of negative health effects. The study by the University of Oregon and the Oregon Social Learning Center looked at daily fluctuations of cortisol levels in men and women.

Older adults’ financial knowledge offsets their declining cognitive ability Getting old doesn’t spell doom when it comes to making important financial decisions, a team of researchers led by a University of California, Riverside assistant professor report in a just published paper. Using credit scores and cognitive ability tests, the researchers found evidence that “crystallized intelligence,” which is gained through experience and accumulated knowledge, is [...]The post Older adults’ financial knowledge offsets their declining cognitive ability appeared first on PsyPost.
Research on guilt-prone individuals has implications for workplace Some people hate to disappoint–and you should definitely get them on your team. It turns out individuals who are highly prone to feel guilty for disappointing their co-workers are among the most ethical and hard-working partners. However, new research suggests that these highly guilt-prone people may be the most reticent to enter into partnerships. Scott [...]The post Research on guilt-prone individuals has implications for workplace appeared first on PsyPost.
The Real Reason You Shouldn't Get Drunk And Write Political Comments We've all done it. We've gone to the wrong website in the wrong mood — or under the influence— and left angry scrawls in the comments. But we shouldn't, and not just because it makes us look stupid. This behavior actually strengthens the position of the people we're arguing against....
Choose to Change A farmer found an eagle’s nest and saw the mother shot dead beside it. In the nest the farmer found a single egg, which he so he took back to his farm and slipped it under one of the hens. The egg eventually hatched with the other eggs under the...
Alan Turing: Exceptional Intellect and Asperger’s British mathematician, logician, cryptanalyst, and pioneering computer scientist Alan Turing led a group of other brilliant codebreakers, including Joan Clarke, at Bletchley Park outside London during WWII to crack the German’s Enigma code. One of his biographers, professor S. Barry Cooper, writes that Turing “was a strange man, who never...
