Researchers at the RIKEN Quantitative Biology Center in Japan, together with collaborators from the University of Tokyo, have developed a method that combines tissue decolorization and light-sheet fluorescent microscopy to take extremely detailed images of the interior of individual organs and even entire organisms. The work, published in Cell, opens new possibilities for understanding the way life works--the ultimate dream of systems biology--by allowing scientists to make tissues and whole organisms transparent and then image them at extremely precise, single-cell resolution.

Belmont, MA--McLean Hospital and Harvard Stem Cell Institute scientists have new evidence that stem cell transplantation could be a worthwhile strategy to help epileptics who do not respond to anti-seizure drugs.
CAMBRIDGE, Mass. (November 6, 2014) - Induced neural stem cells (iNSCs) created from adult cells hold promise for therapeutic transplantation, but their potential in this capacity has been limited by failed efforts to maintain such cells in the desirable multi-potent NSC state without continuous expression of the transcription factors used initially to reprogram them.
ANN ARBOR--Researchers at the University of Michigan have shown how a single neuron can perform multiple functions in a model organism, illuminating for the first time this fundamental biological mechanism and shedding light on the human brain.
Disappointing results in clinical Alzheimer's studies discourage doctors and scientists from continuing their research into ɣ-secretases and a possible treatment against Alzheimer's disease. In the prestigious journal Cell, the Alzheimer's expert Bart De Strooper (VIB-KU Leuven) argues that these studies are not pointless, but merely indicate what the next steps should be for the Alzheimer's research. This article - or rather, this message - will be spread at the largest Neuroscience meeting that will take place mid-November in Washington.
It's a difficult career transition that can lead to more professional frustration and shorter tenure on the job for many of the newest generation of veterans employed with the U.S. Department of Veterans Affairs (VA) compared to their non-veteran co-workers.
New research from the University of Cincinnati is helping VA analyze the process of reintegrating veterans into civilian careers and evaluate methods for easing that transition. That's good news for all veterans as the nation prepares to observe Veterans Day on Nov. 11.
LAWRENCE -- The number of children diagnosed with autism has increased in recent years, but a new study co-authored by a University of Kansas professor shows that while the number of students with autism increased in every state from 2000 to 2007, black and Hispanic children were significantly underrepresented.
BOSTON - (November 6, 2014) - Mary R. Loeken, Ph.D., Investigator in the Section on Islet Cell and Regenerative Biology at Joslin Diabetes Center and Associate Professor of Medicine at Harvard Medical School, has discovered a molecular pathway responsible for neural tube defects in diabetic pregnancies. Her latest research findings in this pathway were published in the October issue of Diabetes.
Women born with a rare condition that gives them a Y chromosome don't only look like women physically, they also have the same brain responses to visual sexual stimuli, a new study shows.
The journal Hormones and Behavior published the results of the first brain imaging study of women with complete androgen insensitivity, or CAIS, led by psychologists at Emory.
URBANA, Ill. – A new online tool developed by researchers at the University of Illinois will further aid studies into postnatal brain growth in human infants based on the similarities seen in the development of the piglet brain, said Rod Johnson, a U of I professor of animal sciences.
People look for candidates with a healthy complexion when choosing a leader, but don't favor the most intelligent-looking candidates except for positions that require negotiation between groups or exploration of new markets. These results are published in the open-access journal Frontiers in Human Neuroscience.
Brian Spisak from the VU University Amsterdam and colleagues studied people's implicit preferences for traits of leaders, such as health, intelligence, and attractiveness, and how they look for information about these qualities in the physical appearance of others.
Rio de Janeiro, Brazil -Individuals show great diversity in their ability to identify scents and odors. More importantly, males and females greatly differ in their perceptual evaluation of odors, with women outperforming men on many kinds of smell tests.
Sex differences in olfactory detection may play a role in differentiated social behaviors and may be connected to one's perception of smell, which is naturally linked to associated experiences and emotions. Thus, women's olfactory superiority has been suggested to be cognitive or emotional, rather than perceptual.
Sometimes, words just complicate things. What if our brains could communicate directly with each other, bypassing the need for language?
AMHERST, Mass. – The surprise discovery of the fossilized skull of a 66- to 70-million-year-old, groundhog-like creature on Madagascar has led to new analyses of the lifestyle of the largest known mammal of its time by a team of specialists including biologist Elizabeth Dumont at the University of Massachusetts Amherst, an expert in jaw structure and bite mechanics.
CHICAGO (November 5, 2014) – When wildfire and people intersect, it is often in the wildland-urban interface, or WUI, a geography where homes, roads and trails intermix with fire-prone vegetation. In an article published Thursday in the journal Nature, U.S. Forest Service scientist Sarah McCaffrey and her colleagues advocate for an approach to wildfire management that reflects ecological science as well as research on the human dimensions of wildfire and fire management.
