Direct link between wound healing, skin cancer seen by researchers. BRISTOL, England, July 1 (UPI) -- Researchers have found that inflammatory cells sent by the immune system to the site of a wound for healing are redirected to pre-cancerous cells they help grow.
While tissue damage and cancer have been linked before, researchers have now seen inflammatory cells called neutrophils be diverted from wounds to pre-cancerous cells in adult zebrafish. Scientists Reverse Aging In Human Cell Line. It’s the Holy Grail for medicine: how to stop or even reverse aging.
With teams of scientists the world over frantically trying to figure out what may cause it, studying everything from nematode worms to naked mole-rats, it seems that a team from Japan might have taken a step forward. Defects in mitochondria, called “the powerhouse of the cell,” as they produce the cells' energy, have long been associated with causing aging-related characteristics such as hair and weight loss, curvature of the spine and osteoporosis. Missing link found between brain, immune system.
Vessels directly connecting brain, lymphatic system exist despite decades of doctrine that they don’tFinding may have substantial implications for major neurological diseases Game-changing discovery opens new areas of research, transforms existing onesMajor gap in understanding of the human body revealed‘They'll have to change the textbooks’ In a stunning discovery that overturns decades of textbook teaching, researchers at the School of Medicine have determined that the brain is directly connected to the immune system by vessels previously thought not to exist.
New Method Could Reveal Your Entire Viral Infection History With A Single Drop Of Blood. By analyzing just a single drop of blood, scientists could reveal every virus you’ve ever been infected with.
This new method, developed by researchers from Howard Hughes Medical Institute (HHMI), is called ‘Virscan’ and it could revolutionize existing diagnostics. Traditional blood tests, known as ELISA assays, are only able detect one pathogen at a time and scientists have yet to develop ELISA assays against all viruses. Is Your Nervous System Being Hacked by Bacteria in Your Gut? The More Hours You Work, the More You Drink, Study Says. David Wolpe is the Max Webb Senior Rabbi of Sinai Temple in Los Angeles.
Religion is America is fading. According to a new Pew Research Center report, almost 23% of all U.S. adults in 2014 said they were religiously unaffiliated, up from about 16% in 2007. While most of the unaffiliated describe themselves as “nothing in particular,” a growing share say they are atheist or agnostic. Why is religion in trouble, and should we be fighting to save it?
Some religious groups are holding fairly steady, including the evangelical and historically black Protestant traditions. The first adversary religion faces is self-sufficiency. The second adversary religion faces is a scientific hegemony over the life of the mind. The third adversary to religion is the decline of genuine community and extended family. Study Of More Than 3,500 Human Brains Reveals The Cause Of Alzheimer's Disease. After examining more than 3,500 donated brains, scientists have gathered evidence to suggest that a rogue protein, tau, which has long been suspected to play a role in the development of Alzheimer’s, is the major driver of cognitive decline in this disease.
These new findings downplay the role of amyloid, another dysfunctional protein that builds up as the condition progresses and has been the focus of much Alzheimer’s research. Although this discovery does not mean that the debate over which protein is the biggest contributor to disease progression is over, it does have implications for future research, and the scientists suggest that therapeutics should now focus on tackling tau, rather than amyloid. The study has been published in Brain. Untitled. Should We All Be In 'Monogamish' Relationships? There’s an argument brewing that says monogamy is not best for a successful relationship.
But is there any science behind it? (Photo: Getty Images) Autism and Air Pollution: New Study Bolsters Suspected Link. Pregnant women may nearly double their risk of giving birth to a child with autism by inhaling smog spewed by vehicles or smoke stacks, according to a new Harvard study that could help unlock the deepest autism mysteries.
The research, released Thursday, fortifies previous scientific findings that linked air pollution to autism. And it offers fresh insights by showing women in their third trimesters seem most vulnerable if they breathe in elevated levels of tiny airborne particles emitted by power plants, fires and automobiles. "We found an association that was specific to pregnancy and especially to the third trimester, identifying a window, which might shed a light on processes that are happening that can lead to autism," said Marc Weisskopf, the report's senior author and associate professor of environmental and occupational epidemiology at the Harvard School of Public Health.
The higher the exposure rate, the greater the risk, he found. The association between discontinuing hormonal contraceptives and wives’ marital satisfaction depends on husbands’ facial attractiveness. Author Affiliations Edited by Steven J.

Marijuana And Cancer: Scientists Find Cannabis Compound Stops Metastasis In Aggressive Cancers. A pair of scientists at California Pacific Medical Center in San Francisco has found that a compound derived from marijuana could stop metastasis in many kinds of aggressive cancer, potentially altering the fatality of the disease forever.
"It took us about 20 years of research to figure this out, but we are very excited," said Pierre Desprez, one of the scientists behind the discovery, to The Huffington Post. "We want to get started with trials as soon as possible. " The Daily Beast first reported on the finding, which has already undergone both laboratory and animal testing, and is awaiting permission for clinical trials in humans. Paul Ryan’s budget flimflam.

Money in the House elections, in 8 charts. This post was prepared in collaboration with Alexander Furnas and Alex Engler. With just over a month before the election, the general consensus is that Democrats will have a tough time picking up the 25 seats they need to win back the house, despite some protestations. But when it comes to the money, Republicans appear to be in solid shape. Jon Stewart Rails Against Fox News' Hypocritical Coverage Of School Lunch Changes. On Thursday night's "Daily Show," Jon Stewart did not hold back his feelings about Fox News' vilification of Michelle Obama for -- dun dun dun -- encouraging children to eat healthier.
The First Lady has made curbing childhood obesity her pet cause during her time in the White House, and part of that agenda included the USDA updating public school cafeteria recommendations to include (slightly) healthier options. Cue the Fox News outrage, because, why not attack each and every thing the Obamas do? Jon wasn't about to let Fox's pundits off the hook. "Why is this news?! " 63,000-Year-Old Modern Human Skull Found in Laos. According to an international team of anthropologists, an ancient skull collected from a cave in the Annamite Mountains in northern Laos is the oldest modern human fossil found in Southeast Asia.
The skull pushes back the clock on modern human migration through the region by as much as 20,000 years and indicates that ancient humans out of Africa left the coast and inhabited diverse habitats much earlier than previously appreciated. The scientists, who found the skull in 2009, were likely the first to dig for ancient bones in Laos since the early 1900s, when a team found 16,000-year-old skulls and skeletons of several modern humans in another cave in the Annamite Mountains. “It’s a particularly old modern human fossil and it’s also a particularly old modern human for that region,” said Dr Laura Shackelford, anthropologist at the University of Illinois and co-author of the study published in the Proceedings of the National Academy of Sciences.
