Researchers uncover vital clues of how the brain erases long term memories

Vital clues about how the brain erases long term memories have been uncovered by researchers. The study in rats reveals how forgetting can be the result of an active deletion process rather than a failure to remember.

Purdue University-led researchers determine structure of Zika virus

A team led by Purdue University researchers is the first to determine the structure of the Zika virus, which reveals insights critical to the development of effective antiviral treatments and vaccines.

Commonly used fungicides could cause gene expression changes in brain cells

Scientists at the UNC School of Medicine have found a class of commonly used fungicides that produce gene expression changes similar to those in people with autism and neurodegenerative conditions, including Alzheimer's disease and Huntington's disease.

Right side of the brain reorganizes itself after stroke to help recover speech-motor functions

New research suggests that looking at structures in the right side of the brain may help predict who will better recover from language problems after a stroke, according to a study published in Neurology, a medical journal of the American Academy of Neurology.

Understanding neuronal feedback could provide new insight into visual perception

Ever see something that isn't really there? Could your mind be playing tricks on you? The "tricks" might be your brain reacting to feedback between neurons in different parts of the visual system, according to a study published in the Journal of Neuroscience by Carnegie Mellon University Assistant Professor of Biological Sciences Sandra J. Kuhlman and colleagues.

Four commonly used medications to treat pregnant women with migraines may not be safe

According to doctors at Wake Forest Baptist Medical Center, medications and treatments long considered safe to treat pregnant women with migraines may not be.

Certain types of hormonal contraceptives may increase risk of seizures in women with epilepsy

Could certain types of hormonal contraceptives cause an increase in seizures in women with epilepsy? A recent Texas A&M Health Science Center study suggests that ethinyl estradiol, the primary component of oral contraceptives, could be detrimental to the epileptic brain.

Memory training with unpredictability more effective in enhancing episodic memory

Memory training with unpredictable components could be more effective in enhancing episodic memory than training with predictable elements, according to new findings from UT Dallas researchers published in the journal Frontiers in Psychology.

Higher aortic stiffness associated with reduced white matter volume among young adults

A large, multi-center study led by the UC Davis School of Medicine for the first time has shown that people as young as their 40s have stiffening of the arteries that is associated with subtle structural damage to the brain that is implicated in cognitive decline and Alzheimer's disease later in life.

Embryos with abnormalities in initial stages of pregnancy may grow into healthy babies

Abnormal cells in the early embryo are not necessarily a sign that a baby will be born with a birth defect such as Down's syndrome, suggests new research carried out in mice at the University of Cambridge. In a study published today in the journal Nature Communications, scientists show that abnormal cells are eliminated and replaced by healthy cells, repairing - and in many cases completely fixing - the embryo.

KAIST researchers develop bio-medical imaging tool to view, analyze live cells

Professor YongKeun Park of the Physics Department at the Korea Advanced Institute of Science and Technology and his research team have developed a powerful method for 3D imaging of live cells without staining. The researchers announced the launch of their new microscopic tool, the holotomography (HT)-1, to the global marketplace through a Korean start-up that Professor Park co-founded, TomoCube.

High levels of radiation dosage may not improve survival of prostate cancer patients

New technology has enabled doctors to administer higher doses of radiation to prostate cancer patients with fewer side effects. However, a new study shows that escalating the dose may not actually help a patient in the long term, at least not patients with localized prostate cancer. The results were published online last week in the American Journal of Clinical Oncology.

New TAU study pinpoints precise mechanism that regulates inheritance of epigenetic responses

According to epigenetics -- the study of inheritable changes in gene expression not directly coded in our DNA -- our life experiences may be passed on to our children and our children's children. Studies on survivors of traumatic events have suggested that exposure to stress may indeed have lasting effects on subsequent generations. But how exactly are these genetic "memories" passed on?

Certain gut bacteria can influence the immune system to reduce severity of stroke

Certain types of bacteria in the gut can leverage the immune system to decrease the severity of stroke, according to new research from Weill Cornell Medicine. This finding can help mitigate stroke -- which is the second leading cause of death worldwide.

Scientists identify two enzymes that appear to play role in metabolism, inflammation

A team led by scientists at The Scripps Research Institute and the Salk Institute for Biological Studies has discovered two enzymes that appear to play a role in metabolism and inflammation—and might someday be targeted with drugs to treat type 2 diabetes and inflammatory disorders.

Stem cell-derived neurons used to regenerate lost tissue in damaged corticospinal tracts of rats

Writing in the March 28, 2016 issue of Nature Medicine, researchers at University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System, with colleagues in Japan and Wisconsin, report that they have successfully directed stem cell-derived neurons to regenerate lost tissue in damaged corticospinal tracts of rats, resulting in functional benefit.

MGH study finds that the brains of young marijuana users react differently to social exclusion

A study from Massachusetts General Hospital researchers finds that the brains of young adult marijuana users react differently to social exclusion than do those of non-users. In a report published in the March issue of Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, the team reports that activation of the insula, a region of the brain that is usually active during social rejection, was reduced in young marijuana users when they were being excluded from participation in virtual game of catch.

Study demonstrates possibility of simultaneous improvement in all mental, physical functions

Let's say you've decided to make some changes in your life. You're out of shape, your mind wanders, your self-esteem is wavering, and you have no idea what you just read. So you decide to focus on one thing -- losing weight, maybe -- and tackle the other issues later. You don't want to take on too much at once, right?

Neuroscientists decipher new pathway in stem cell differentiation

How do neurons become neurons? They all begin as stem cells, undifferentiated and with the potential to become any cell in the body.Until now, however, exactly how that happens has been somewhat of a scientific mystery. New research conducted by UC Santa Barbara neuroscientists has deciphered some of the earliest changes that occur before stems cells transform into neurons and other cell types.

Findings could help explain origin of type 2 diabetes in children of obese mothers

A new study led by researchers at The Saban Research Institute of Children's Hospital Los Angeles reports that the presence of leptin - a hormone secreted by fat cells that is critical to maintaining energy balance in the body -- inhibits the prenatal development of neuronal connections between the brain and pancreas. The findings could help explain the origin of type 2 diabetes, particularly in children of obese mothers.
