Cooperative Neural Networks Suggest How Intelligence Evolved Working together can hasten brain evolution, according to a new computer simulation. When programmed to navigate challenging cooperative tasks, the artificial neural networks set up by scientists to serve as mini-brains "learned" to work together, evolving the virtual equivalent of boosted brainpower over generations. The findings support a long-held theory that social interactions may have triggered brain evolution in human ancestors.
Travel Inside 3D Cells in Full Color on Your Laptop March 7, 2015 (Nanowerk News) Nanolive SA announces the release of an off-line version of STEVE. “Starting from today, scientists, Medical Doctors and students all around the world will be enabled to travel inside 3D cells in full color by simply downloading STEVE on their laptop” declares Dr. Yann Cotte, CEO and co-founder of Nanolive SA.Nanolive SA is a Swiss start-up company, based at Innovation Park in Lausanne, which is developing a revolutionary microscope (and a revolutionary software) able to image and digitally stain living cells in 3D without any sample preparation and in real-time. The company, which has already received more than 45 pre-orders (with partial up-front payments), is planning the market entry for this summer.STEVEThe value measured by the 3D Cell Explorer is not fluorescence intensity of an exogenous molecule like with most optical microscopes.
20 Amazing Facts About Your Brain The human brain is amazing and the more I read about it the more fascinated I become with not only it’s limitations, but also it’s immense power. Since I originally wrote the post 30 Amazing Facts About Your Brain I have been on the look out for more amazing tidbits. Here are another 20 for you to wrap your head round, but don’t make the mistake of thinking they don’t apply to you, because they do. Eating green leafy vegetables keeps mental abilities sharp Something as easy as adding more spinach, kale, collards and mustard greens to your diet could help slow cognitive decline, according to new research. The study also examined the nutrients responsible for the effect, linking vitamin K consumption to slower cognitive decline for the first time. "Losing one's memory or cognitive abilities is one of the biggest fears for people as they get older," said Martha Clare Morris, Sc.D., assistant provost for community research at Rush University Medical Center and leader of the research team. "Since declining cognitive ability is central to Alzheimer's disease and dementias, increasing consumption of green leafy vegetables could offer a very simple, affordable and non-invasive way of potentially protecting your brain from Alzheimer's disease and dementia."
The Brain's Highways: Mapping the Last Frontier Frontiers are in short supply. No explorer will again catch that first glimpse of the Pacific Ocean with “wild surmise,” take the first steps on the moon, or arrive first at the Challenger deep – the remotest corners of the earth are now tourist attractions. Even in science, great mysteries have fallen – life itself has gone from being the subject of metaphysical speculation about vital substances to the biophysical understanding of cellular processes. Learn Science at Scitable Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life. Focusing on the cell permits a detailed understanding of the tissues and organisms that cells compose. Some organisms have only one cell, while others are organized into cooperative groups with huge numbers of cells. On the whole, cell biology focuses on the structure and function of a cell, from the most general properties shared by all cells, to the unique, highly intricate functions particular to specialized cells.
This Nifty Infographic is a Great Introduction to Neuroplasticity and Cognitive Therapy It's startling to think about how we've got a spaceship billions of miles away rendezvousing with Pluto, yet here on Earth there are major aspects of our own anatomy that we're almost completely ignorant about. We've climbed Everest, sent men to the moon, and invented the Internet — but we still don't know how our brains work. The positive outlook is that many health, science, and research specialists believe we're on the precipice of some major neuroscientific breakthroughs. One example of a recent discovery with major implications is our further understanding of neuroplasticity. Simply put, we used to think our brain was what it was — unchangeable, unalterable.
Daily Marijuana Use Doesn’t Really Change Brains of Adults or Teens, Study Finds Last year, the press and marijuana-legalization opponents gave a lot of attention to a study suggesting that daily marijuana causes abnormalities in the brain. New research, reportedly using better techniques, indicates that claim and other reports of cannabis-caused changes to brain structure simply aren't true. The authors of the new study, "Daily Marijuana Use Is Not Associated with Brain Morphometric Measures in Adolescents or Adults," published in the latest edition of the Journal of Neuroscience, suggest that alcohol use was responsible for previous studies finding brain changes. An abstract of the study's findings was published last week on the Journal's website. It describes how scientists could not replicate recent research that claimed the use of cannabis "is associated with volumetric and shape differences in subcortical structures..."

'Moonlighting' Molecules Discovered; Researchers Uncover New Kink In Gene Control Since the completion of the human genome sequence, a question has baffled researchers studying gene control: How is it that humans, being far more complex than the lowly yeast, do not proportionally contain in our genome significantly more gene-control proteins? Now, a collaborative effort at the Johns Hopkins School of Medicine to examine protein-DNA interactions across the whole genome has uncovered more than 300 proteins that appear to control genes, a newly discovered function for all of these proteins previously known to play other roles in cells. The results, which appear in the October 30 issue of Cell, provide a partial explanation for human complexity over yeast but also throw a curve ball in what we previously understood about protein functions. The team set out to figure out which proteins encoded by the genome bind to which DNA sequences.
