Testing how well people remember past events in their lives could help medical professionals make early predictions about who is at risk for developing Alzheimer’s disease, according to a new study from the University of Arizona. Researchers administered an “autobiographical memory” test to a group of 35 healthy adults, about half of whom carry the

Lectures are a staple of higher education, and understanding how students interact and learn within the lecture theatre environment is central to successful learning. In a new study published in FEBS Open Bio, researchers examined students’ reasons for choosing particular seats in a lecture hall, and investigated how seating positions correlate with student performance. Many

FRIDAY, Aug. 10, 2018 — The American Medical Association (AMA) House of Delegates has adopted a policy on augmented intelligence, according to a report published in the association’s AMA Wire. Though computational methods, techniques, and systems for data analysis such as machine image recognition are often called artificial intelligence, a more appropriate term for their

Researchers have found that women who play soccer may be more at risk than their male counterparts. According to a new study published in the journal Radiology, female soccer players exhibit more extensive changes to brain tissue after repetitive ‘heading’ of the soccer ball. Soccer is the most popular competitive sport in the world, and

Aging vessels connecting the brain and the immune system play critical roles in both Alzheimer’s disease and the decline in cognitive ability that comes with time, new research reveals. By improving the function of the lymphatic vessels, scientists at the University of Virginia School of Medicine have dramatically enhanced aged mice’s ability to learn and

Students who lived in dormitories without air conditioning (AC) during a heat wave performed worse on a series of cognitive tests compared with students who lived in air-conditioned dorms, according to new research led by Harvard T.H Chan School of Public Health. The field study, the first to demonstrate the detrimental cognitive effects of indoor

Being aware of our surroundings is a fundamental aspect of our existence. But what in our biological makeup determines how we access and interpret the endless stream of information around us? A new Tel Aviv University study published in Current Biology suggests that noradrenaline, a neurotransmitter responsible for arousal in the brain, plays a vital

Researchers from the University of Michigan found that serum levels of two biomarkers of traumatic brain injury, tau and ubiquitin C-terminal hydrolase L1, are elevated following high-acceleration head impacts, even when there is no clinical diagnosis of concussion. Their complete findings are reported today in the Journal of Neurosurgery, in the article “Elevated markers of

When playing an economic game those that were assigned as ‘lower status’ were more likely to share their wealth than their ‘higher status’ counterparts, according to a new study at Queen Mary University of London. The social experiment involved a series of economic games in which people played with other people for real money. The

A new computational-model designed by researchers at UCL based on data from the Champalimaud Centre for the Unknown reveals that serotonin, one of the most widespread chemicals in the brain, can speed up learning. Serotonin is thought to mediate communications between neural cells and play an essential role in functional, and dysfunctional, cognition. For a

Our eye hosts a powerful biological computer, the retina. Understanding how the retina transforms images from the outside world into signals that the brain can interpret would not only result in insights into brain computations, but could also be useful for medicine. As machine learning and artificial intelligence develop, eye diseases will soon be described

For a thousand years, people have reported feeling better by meditating but there has never been a systematic study that quantified stress and how much stress changes as a direct result of meditation until now. U.S. Army Research Laboratory researchers spent a year collaborating with a team of scientists from the University of North Texas

A year of schooling leaves students with new knowledge, and it also equates with a small but noticeable increase to students’ IQ, according to a systematic meta-analysis published in Psychological Science, a journal of the Association for Psychological Science. “Our analyses provide the strongest evidence yet that education raises intelligence test scores,” says psychological scientist

Anxious people take fewer risks — this is not surprising. However, a team of psychologists from the German Friedrich Schiller University Jena, together with partners from Würzburg in Germany and the Canadian University of Victoria have succeeded in making this decision process visible in the brain, allowing them to predict the behaviour of individuals. They

Excessive drinking during adolescence may interfere with the activity of brain cells needed for sustaining short term memory, according to new research in adolescent male mice published in JNeurosci. The study could help scientists better understand the development of alcohol use disorders in adults. The prefrontal cortex (PFC) and the behavior-management abilities it supports —

Memories of traumatic experiences can lead to mental health issues such as post-traumatic stress disorder (PTSD), which can destroy a person’s life. It is currently estimated that almost a third of all people will suffer from fear- or stress-related disorders at one point in their lives. Now, a new study shows — at the cellular

New findings from the long-running Whitehall II study of over 10,000 civil servants has found 50-year-olds who had blood pressure that was higher than normal but still below the threshold commonly used when deciding to treat the condition, were at increased risk of developing dementia in later life. This increased risk was seen even when

Several studies have suggested that intensive musical training enhances children’s linguistic skills. Such training, however, is not available to all children. Researchers at Cognitive Brain Research Unit in the University of Helsinki studied in a community setting whether a low-cost, weekly music playschool provided to 5-6-year-old children in kindergartens affects their linguistic abilities. The children

The coordination of neural activity across widespread brain networks is essential for human cognition. Researchers have long assumed that oscillations in the brain, commonly measured for research purposes, brain-computer interfacing, and clinical tests, were stationary signals that occurred independently at separate brain regions. Biomedical engineers at Columbia Engineering have discovered a new fundamental feature of

Struggling to finish that report for your boss? One way to increase your interest in a task is to add immediate rewards, rather than wait until the end to reward yourself, according to new Cornell research published in the Journal of Personality and Social Psychology titled “It’s About Time: Earlier Rewards Increase Intrinsic Motivation.” Kaitlin
