Study shows mindfulness training can help reduce teacher stress and burnout

MADISON, Wis. – Teachers who practice "mindfulness" are better able to reduce their own levels of stress and prevent burnout, according to a new study conducted by the Center for Investigating Healthy Minds (CIHM) at the University of Wisconsin-Madison Waisman Center.

The results of the study, led by Assistant Scientist Lisa Flook, were recently published in the journal Mind, Brain and Education.

A major cause of age-related memory loss identified

NEW YORK, NY (August 28, 2013) — A team of Columbia University Medical Center (CUMC) researchers, led by Nobel laureate Eric R. Kandel, MD, has found that deficiency of a protein called RbAp48 in the hippocampus is a significant contributor to age-related memory loss and that this form of memory loss is reversible. The study, conducted in postmortem human brain cells and in mice, also offers the strongest causal evidence that age-related memory loss and Alzheimer's disease are distinct conditions.

UC Davis team 'spikes' stem cells to generate myelin

(SACRAMENTO, Calif.) — Stem cell technology has long offered the hope of regenerating tissue to repair broken or damaged neural tissue. Findings from a team of UC Davis investigators have brought this dream a step closer by developing a method to generate functioning brain cells that produce myelin — a fatty, insulating sheath essential to normal neural conduction.

Researchers discover a potential cause of autism

CHAPEL HILL, N.C. -- Problems with a key group of enzymes called topoisomerases can have profound effects on the genetic machinery behind brain development and potentially lead to autism spectrum disorder (ASD), according to research announced today in the journal Nature. Scientists at the University of North Carolina School of Medicine have described a finding that represents a significant advance in the hunt for environmental factors behind autism and lends new insights into the disorder's genetic causes.

Autistic children can outgrow difficulty understanding visual cues and sounds

BRONX, NY -- Scientists at Albert Einstein College of Medicine of Yeshiva University have shown that high-functioning autism spectrum disorder (ASD) children appear to outgrow a critical social communication disability. Younger children with ASD have trouble integrating the auditory and visual cues associated with speech, but the researchers found that the problem clears up in adolescence. The study was published today in the online edition of the journal Cerebral Cortex.

Expectant mothers' periodontal health vital to health of her baby

Chicago, IL – (August 27, 2013) – When a woman becomes pregnant, she knows it is important to maintain a healthy lifestyle to ensure both the health of herself and the health of her baby. New clinical recommendations from the American Academy of Periodontology (AAP) and the Eurpean Federation of Periodontology (EFP) urge pregnant women to maintain periodontal health as well. Research has indicated that women with periodontal disease may be at risk of adverse pregnancy outcomes, such giving birth to a pre-term or low-birth weight baby, reports the AAP and EFP.

Combating concussions

SAN DIEGO, Calif. (August 28, 2013) — In the United States there are millions of sports related concussions each year, but many go undiagnosed because for some athletes, the fear of being benched trumps the fear of permanent brain damage, and there is no objective test available to accurately diagnose concussions on the sidelines.

Researchers at San Diego State University have set out to change that.

Forensic experts may be biased by the side that retains them

Forensic psychologists and psychiatrists are ethically bound to be impartial when performing evaluations or providing expert opinions in court. But new research suggests that courtroom experts' evaluations may be influenced by whether their paycheck comes from the defense or the prosecution. The research is published in Psychological Science, a journal of the Association for Psychological Science.

Size of personal space is affected by anxiety

The space surrounding the body (known by scientists as 'peripersonal space'), which has previously been thought of as having a gradual boundary, has been given physical limits by new research into the relationship between anxiety and personal space.

New findings have allowed scientists to define the limit of the 'peripersonal space' surrounding the face as 20-40cm away. The study is published today in The Journal of Neuroscience.

Kessler Foundation researcher reports pilot results from a virtual reality executive function task

WEST ORANGE, N.J. August 27, 2013. —Denise Krch, Ph.D., research scientist for Traumatic Brain Injury (TBI) Research at Kessler Foundation, presented "Pilot results from a virtual reality executive function task," at the International Conference on Virtual Rehabilitation (ICVR). In the pilot study, Dr. Krch evaluated the Assessim Office (AO), a virtual reality office task, in participants with multiple sclerosis (MS) and TBI.

Report proposes microbiology's grand challenge to help feed the world

A greater focus on the role of microbiology in agriculture combined with new technologies can help mitigate potential food shortages associated with world population increases according to a new report from the American Academy of Microbiology.

Fractions gain traction with concrete models

This news release is available in French.

Montreal, August 27, 2013 — If 3 is greater than 2, then ⅓ must be bigger than ½ — right? Wrong. As thousands of students head back to school, many will use exactly that kind of thinking when faced with fractions for the first time. New research from Concordia University shows that for children to understand math, teachers must constantly make the connection between abstract numbers and real world examples.

Researcher controls colleague's motions in first human brain-to-brain interface

University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.

Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other side of the UW campus, causing Stocco's finger to move on a keyboard.

Hearing loss associated with a lack of cell-cell junctions

Sound waves are filtered through the outer ear to the cochlea, where hair cells convert the sound into the electric impulses that travel through the auditory nerve to the brain.

Dating violence impedes victims' earnings

EAST LANSING, Mich. — Dating violence in adolescence not only takes a physical and emotional toll on young women, it also leads to less education and lower earnings later in life, according to a first-of-its-kind study led by a Michigan State University researcher.

A young woman's educational performance may be hindered by her partner's actions, such as destroying books or homework or causing injuries that prevent her from going to school.
