Researchers have identified the brain regions involved in choosing whether to find out if a bad event is about to happen.

Rudeness leads to anchoring, including in medical diagnoses

Research looks at how experiencing rudeness amplifies anchoring bias including in doctors' decision-making.

Leaders who embrace on-job learning and listen to employees have more resilient teams

Leaders who encourage their employees to learn on the job and speak up with ideas and suggestions for change have teams that are more effective and resilient in the face of unexpected situations, according to new research.

Study sheds light on treatment options for devastating childhood brain cancer

Posted: 10 Jun 2021 01:24 PM PDT

Research suggests that children with average risk medulloblastoma can receive radiation to a smaller volume of the brain at the end of a six-week course of treatment and still maintain the same disease control as those receiving radiation to a larger area. But the dose of preventive radiation treatments given to the whole brain and spine over the six-week regimen cannot be reduced without reducing survival.

Study identifies how COVID-19 linked to Alzheimer's disease-like cognitive impairment

Posted: 10 Jun 2021 01:24 PM PDT

A new study has identified mechanisms by which COVID-19 can lead to Alzheimer's disease-like dementia. The findings indicate an overlap between COVID-19 and brain changes common in Alzheimer's, and may help inform risk management and therapeutic strategies for COVID-19-associated cognitive impairment.

Forget me not: Novel target shows promise in treating Alzheimer's and related dementias

Posted: 10 Jun 2021 01:23 PM PDT

Researchers have identified a previously unknown early driver of Alzheimer's disease (AD) and vascular dementia (VaD). They report high levels of cis P-tau, a pathogenic protein, in human AD and VaD brains as well as preclinical disease models. Treatment with an antibody to the toxic protein prevented disease progression and reversed disease symptoms and restored cognitive function in older mice.

Music listening near bedtime disruptive to sleep

Posted: 10 Jun 2021 01:23 PM PDT

Most people listen to music throughout their day and often near bedtime to wind down. But can that actually cause your sleep to suffer? When a sleep researcher realized he was waking in the middle of the night with a song stuck in his head, he saw an opportunity to study how music -- and particularly stuck songs -- might affect sleep patterns.

'Roadmaps' of the brain reveal regions vulnerable to Alzheimer's disease

Posted: 10 Jun 2021 12:01 PM PDT

Much like a supply truck crossing the countryside, the misfolded proteins that damage neurons in Alzheimer's disease travel the 'roads' of the brain, sometimes stopping and sometimes re-routing to avoid roadblocks.

Cell phone use while driving may be tied to other risky road behaviors in young adults

Posted: 10 Jun 2021 11:45 AM PDT

A new study found that 18- to 24-year-olds who use cell phones while driving are more likely to engage in other risky driving behaviors associated with 'acting-without-thinking,' a form of impulsivity. These findings suggest the importance of developing new strategies to prevent risky driving in young adults, especially those with impulsive personalities.

Could naked mole rats hold key to curing cancer and dementia?

Posted: 10 Jun 2021 10:57 AM PDT

Scientists say naked mole rats - a rodent native to West Africa - may hold the key to new treatments for degenerative diseases such as cancer and dementia.

Three factors may predict college students' loss of self-control

Posted: 10 Jun 2021 10:55 AM PDT

Researchers determined willingness to try new things along with parental attachment could be indicators of self-control among first-year students.

Cells construct living composite polymers for biomedical applications

Posted: 10 Jun 2021 10:55 AM PDT

Biomedical engineers have demonstrated that a class of interwoven composite materials called semi-interpenetrating polymer networks (sIPNs) can be produced by living cells. The approach could make these versatile materials more biologically compatible for biomedical applications such as time-delayed drug delivery systems.

Humans are ready to take advantage of benevolent AI

Posted: 10 Jun 2021 10:55 AM PDT

Humans expect that AI is benevolent and trustworthy. A new study reveals that at the same time humans are unwilling to cooperate and compromise with machines. They even exploit them.

Memory biomarkers confirm aerobic exercise helps cognitive function in older adults

Posted: 10 Jun 2021 10:55 AM PDT

Until now, systemic biomarkers to measure exercise effects on brain function and that link to relevant metabolic responses were lacking. A study shows a memory biomarker, myokine Cathepsin B (CTSB), increased in older adults following a 26-week structured aerobic exercise training. The positive association between CTSB and cognition, and the substantial modulation of lipid metabolites implicated in dementia, support the beneficial effects of exercise training on brain function and brain health in asymptomatic individuals at risk for Alzheimer's.

Cloud computing expands brain sciences

Posted: 10 Jun 2021 10:38 AM PDT

People often think about human behavior in terms of what is happening in the present -- reading a newspaper, driving a car, or catching a football. But other dimensions of behavior extend over weeks, months, and years.

Rural residents, American Indians travel farthest for certified stroke care

Posted: 10 Jun 2021 06:11 AM PDT

Race, age, income and health insurance status are factors in the distance patients must travel to reach the nearest certified stroke care, according to a nationwide analysis of US census data and road maps. The greatest distances were for those in rural areas and for American Indians.

Flickering screens may help children with reading and writing difficulties, study suggests

Posted: 10 Jun 2021 06:10 AM PDT

Children with reading and writing difficulties who are presented with text on screens with flickering white noise both read better and remember what they have read better, according to a Swedish-Norwegian study.

Largescale brain epigenetics study provides new insights into dementia

Posted: 10 Jun 2021 06:10 AM PDT

The team looked in different regions of the brain, which are affected in Alzheimer's disease before looking for common changes across these cortical regions. They identified 220 sites in the genome, including 84 new genes, which showed different levels of DNA methylation in the cortex in individuals with more severe Alzheimer's disease, which weren't seen in the cerebellum.

Predisposition to addiction may be genetic, study finds

Posted: 10 Jun 2021 06:10 AM PDT

People who have a high sensation-seeking trait in the brain could be more susceptible to drug addition, according to a new study.

High caffeine consumption may be associated with increased risk of blinding eye disease

Frequent caffeine intake could more than triple risk of glaucoma for those genetically predisposed to higher eye pressure.
