7:00 PM | 30 minutes cycling (equivalent to half a spin class) promotes brain plasticity
Don’t have time to exercise? Remember the blog post I wrote about Tony Abbott, Barak Obama and Richard Branson and how they find time every day to exercise? I believe success goes hand in hand with exercise because the world’s most successful people exercise every day. President Obama, possibly one of the world’s busiest people, works […] The post 30 minutes cycling (equivalent to half a spin class) promotes brain plasticity appeared first on Your Brain Health.

5:28 PM | Affordable Care Act: Playing Politics Can Be Hazardous To Your Health
Proponents of the Affordable Care Act are getting exactly the cultural result they wanted. They are able to declare victory because of a decrease in health care costs but don't mention it is because there has been a decrease in people using their insurance because of high out-of-pocket costs.In this election season, it is imperative to remember those who voted for this disaster without having read the bill, those who demonized people who raised valid questions about access to care, costs and […]

5:01 PM | Sadness Lasts 240X Longer Than Other Emotions
A new psychology paper says people feel sad up to 240 times longer than they do ashamed, surprised, irritated or even bored. The reason may be because sadness often goes hand in hand with events of greater impact such as death or accidents and so we need more time to mull over and cope with what happened to fully comprehend it, say Philippe Verduyn and Saskia Lavrijsen of the University of Leuven in Belgium, who asked 233 high school students to recollect recent emotional episodes and report […]

4:41 PM | Analyze your zombie walk
Imagine a zombie costume.   You probably see – pale, bloody makeup, ripped clothes, dead-eyed stare. All of that preparation, however, would not be convincing if the zombie were to just move around normally. In fact “Walking Dead” special effects artist/director Greg Nicotero teaches a school on how to lumber around like a zombie for […]

J. Marion Sims by Jim.Henderson, CC BY-SABy David T. Z. Mindich, St. Michael's CollegeOn an October day in 1894, a group of New York City’s leading doctors gathered to unveil a statue in honor of one of the greatest surgeons of his day and the founder of New York’s Women’s Hospital, J.

3:20 PM | Alcoholism as a Reward System Dysfunction
Alcoholism and other addictive behaviors often occur together within individual patients.For example, individuals with alcoholism commonly also are smokers and meet criteria for a diagnosis of nicotine dependence.This co-occurrence suggests multiple types of addiction may share genetic and environmental risk factors. Additionally, there might be a common neurobiological mechanism in play for many addictions.Kenneth Blum and other leading alcoholism researchers recently published a review that […]

3:05 PM | Reverting To The Standard Before School Lunches Were Politicized Would Lead To More Childhood Obesity
In 2012, the Obama administration made the National School Lunch Program, which has provided free or reduced-cost meals in more than 100,000 public and non-profit private schools and other child-care institutions nationwide since 1946, into a political football and used beliefs that lacked any scientific basis to mandate what should be served. Schools and communities went into open revolt. For the children we care most about, those school lunches might be the best meal they got, and those […]

2:38 PM | US Wildlife Bans On GMOs And Neonics Lack Transparency And Scientific Rationale
By Val Giddings, Genetic Literacy ProjectWith little fanfare, last summer the U.S. Fish  &  Wildlife Service announced it would formally ban the use of seeds treated with neonicotinoid pesticides, (a newer, safer generation of seed treatments to protect against pests) and the use of crops improved through biotechnology throughout the fish and wildlife refuge system. read more

2:31 PM | Now That People Are Thinking About Ebola Vaccines, Pay More Attention To Measles
Measles is one of the most contagious of vaccine-preventable diseases, with the average person with measles capable of infecting 12-18 people if susceptible, and the contagiousness of measles infection highlights gaps in vaccination in the United States that have appeared over the last decade, because of skepticism about childhood vaccination in coastal states like California and Oregon and Washington. In those states, otherwise educated people worry that vaccines may cause autism and would […]

2:30 PM | The Risks And Rewards Of Two Popular Gastric Bypass Procedures
A recent study compared two of the most commonly performed bariatric surgery procedures. There are tradeoffs between the two surgical approaches in potential risks and benefits and so there has been an ongoing debate about which can achieve weight loss, with conflicting results in systematic reviews.  The two procedures were laparoscopic Roux-en-Y gastric bypass (RYGB) and adjustable gastric banding (AGB). The result was that RYGB resulted in much greater weight loss than AGB but had […]

2:00 PM | Jays Find Others’ Food Stashes Through Eavesdropping
Eurasian Jays are known for caching food and remembering its location for later. They’re also known for their tendency to pilfer the caches of other jays.

12:18 PM | Homeopathy for Ebola
New Zealand Green MP, Steffan Browning, stepped in it recently when he signed a petition asking the World Health Organization (WHO) to develop and distribute homeopathic remedies to end the Ebola epidemic. Unfortunately this is not an Onion article. Browning later tried to do damage control by stating that his support of the petition was “unwise” [...]

11:38 AM | Fright Week: The Stranger in the Mirror
In the mirror we see our physical selves as we truly are, even though the image might not live up to what we want, or what we once were. But we recognize the image as “self”. In rare instances, however, this reality breaks down.In Black Swan, Natalie Portman plays Nina Sayers, a ballerina who auditions for the lead in Swan Lake. The role requires her to dance the part of the innocent White Swan (for which she is well-suited), as well as her evil twin the Black Swan — which is […]

10:30 AM | The psychology of "mate poaching" - when you form a relationship by taking someone else's partner
According to one estimate, 63 per cent of men and 54 per cent of women are in their current long-term relationships because their current partner "poached" them from a previous partner. Now researchers in the US and Australia have conducted the first investigation into the fate of relationships formed this way, as compared with relationships formed by two unattached individuals.An initial study involved surveying 138 heterosexual participants (average age 20; 71 per cent were women) four times […]

2:59 AM | Why the brain uses “sparse codes”
In 1972, Horace Barlow, great-grandson of Darwin, wrote an article in which he put forth “A neuron doctrine for perceptual psychology?” (The question mark at the end shows that Barlow was a contemplative guy.) With this doctrine, Barlow tried to relate the firing of neurons in sensory pathways with subjectively experienced sensation. One of the […]

10:17 PM | Mini Human Stomach Created In The Lab - Using Adult Stem Cells
Induced pluripotent stem cells (iPSCs) became the target of researchers a decade ago due to restrictions on federal funding for human embryonic stem cells (hESCs). While media reports were claiming biology was dead if President Bush didn't violate President Clinton's Dickey-Wicker law, researchers instead moved to iPSCs and now they have been able to generate functional, three-dimensional human stomach tissue in a laboratory.read more
