New findings on Alzheimer's disease presented at Neuroscience 2012

Curtailing the imminent rise in Alzheimer's disease (AD) will require early, accurate diagnostic tests and treatments, and researchers are closer to achieving these two goals. New findings in medical imaging, molecular analysis of neurological diseases, and development of treatments using mouse models were presented at Neuroscience 2012, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

DNA method leads to more effective treatment of neuroblastoma in children

After leukaemia and brain tumours, neuroblastoma is the most common form of cancer to affect children. A thesis from the Sahlgrenska Academy, University of Gothenburg, Sweden, has studied a DNA method which is now used for all cases of neuroblastoma in Sweden, and which has led to more effective treatment at individual level.

Females having multiple sexual partners may be more fertile

Researchers have discovered that females that have multiple sexual partners can be more fertile than those that are monogamous and, very surprisingly, that this is the result of an "overproduction" of sons. The study - still only published as a provisional article but already one of the most accessed in BCM Evolutionary Biology - helps to explain a puzzle that has been haunting evolutionary biologist for decades: why during a mating season so many females chase multiple sexual partners when one is enough to fertilize all her eggs and to do it is costly and dangerous.

Regulatory B cells may provide effective treatment for severe autoimmune diseases

Reproducing a rare type of B cell in the laboratory and infusing it back into the body may provide an effective treatment for severe autoimmune diseases such as multiple sclerosis or rheumatoid arthritis, according to researchers at Duke University Medical Center.

New research on how the brain develops during transition period from childhood to adulthood

Scientists presented new research today on how the brain develops during the dynamic and vulnerable transition period from childhood to adulthood. The findings underscore the uniqueness of adolescence, revealing factors that may influence depression, decision-making, learning, and social relationships.

White blood cell variation can help predict non-blood cancers

Postdoctoral Research Fellow Devin Koestler is a biostatistician in the Geisel School of Medicine at Dartmouth. He develops and applies statistical methods to large volumes of data, seeking new approaches for understanding disease, cancer in particular. Koestler and his colleagues are investigating the potential use of white blood cell variation as a diagnostic, predictive, and research tool in the study of non-blood cancers.

Embryonic neuron transplants could effectively treat brain diseases

The unexpected survival of embryonic neurons transplanted into the brains of newborn mice in a series of experiments at the University of California, San Francisco (UCSF) raises hope for the possibility of using neuronal transplantation to treat diseases like Alzheimer's, epilepsy, Huntington's, Parkinson's and schizophrenia.

Scientists reveal interaction between the auditory cortex and amygdala

In a study published in the Journal of Neuroscience and funded by the Wellcome Trust, Newcastle University scientists reveal the interaction between the region of the brain that processes sound, the auditory cortex, and the amygdala, which is active in the processing of negative emotions when we hear unpleasant sounds.

Teagasc researchers look to seaweed for proteins with health benefits

Teagasc researchers are looking to seaweed for proteins with health benefits for use as functional foods. Historically, edible seaweeds were consumed by coastal communities across the world and today seaweed is a habitual diet in many countries, particularly in Asia.

Pregnancy stress can cut brain benefits of motherhood

A new study in animals shows that chronic stress during pregnancy prevents brain benefits of motherhood, a finding that researchers suggest could increase understanding of postpartum depression.

Variable methylation predictive of age, gender, stress, cancer and early-life socioeconomic status

A Simon Fraser University physicist has helped discover that understanding how a chemical mark on our DNA affects gene expression could be as useful to scientists as fingerprints are to police at a crime scene.

Pioneering research paves way for new treatments for pulmonary arterial hypertension

Pioneering research conducted by the University of Sheffield is paving the way for new treatments which could benefit patients suffering from the fatal lung disease pulmonary arterial hypertension (PAH).

Chromosome 3p21.1 locus contains common genetic risk for bipolar disorder

One of the biggest challenges in psychiatric genetics has been to replicate findings across large studies. Scientists at King's College London, Institute of Psychiatry have now performed one of the largest ever genetic replication studies of bipolar affective disorder, with 28,000 subjects recruited from 36 different research centers. Their findings provide compelling evidence that the chromosome 3p21.1 locus contains a common genetic risk for bipolar disorder, the PBRM1 gene.

New insights into how brain responds to extreme stress

Researchers report new insights into how the brain responds to extreme stress, whether from combat, natural disasters, or repeated violent competition. The insights offer hope for detecting and treating several widespread and debilitating neuropsychiatric disorders, and were presented at Neuroscience 2012, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

UMass Amherst neuroscientist to receive 2012 Frank A. Beach Award from SBN

UMass Amherst neuroscientist Luke Remage-Healey will receive the 2012 Frank A. Beach Award from the Society for Behavioral Endocrinology for work showing exceptional promise and significant contributions in the field of behavioral neuroendocrinology. Named after a founder of the field, the award will be presented during the society's annual meeting this week in New Orleans. Remage-Healey will also give a lecture at the society's annual meeting next year.

Study helps uncover how brain processes and interprets facial expressions

Research released today helps reveal how human and primate brains process and interpret facial expressions, and the role of facial mimicry in everything from deciphering an unclear smile to establishing relationships of power and status.

Researchers identify keys and doors of Anaplasmataceae tick-borne bacterium

Virginia Commonwealth University School of Medicine researchers have identified the "keys" and "doors" of a bacterium responsible for a series of tick-transmitted diseases. These findings may point researchers toward the development of a single vaccine that protects against members of an entire family of bacteria that cause disease in humans, domestic animals and livestock.

Scientists resolve new molecular circuit controlling cellular metabolism

Cancer, diabetes, and excess body weight have one thing in common: they alter cellular metabolism. Scientists from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the Medical University of Vienna together with an international research team have jointly resolved a new molecular circuit controlling cellular metabolism.
