We've called autism a disease for decades. We were wrong. U.S. scientists successfully turn human cancer cells back to normal in process that could ‘switch off’ disease. Cancer cells have been programmed back to normal by scientists in a breakthrough which could lead to new treatments and even reverse tumour growth.
For the first time, aggressive breast, lung and bladder cancer cells have been turned back into harmless benign cells by restoring the function which prevents them from multiplying excessively and forming dangerous growths. Scientists at the Mayo Clinic in Florida in the U.S. said it was like applying the brakes to a speeding car. So far it has only been tested on human cells in the lab, but the researchers are hopeful that the technique could one day be used to target tumours so that cancer could be “switched off” without the need for harsh chemotherapy or surgery. Researchers identify protein that spreads cancer. Tuesday July 14 2015 Researchers found the DNA-PKcs molecules helped spread cancer "Scientists have found a way of preventing the spread of cancer from the site of the original tumour," The Independent reports.
Targeting proteins called DNA-PKcs could prevent cancer cells moving to other parts of the body. This is known as metastatic cancer and is often fatal. The research involved mice as well as tissue samples from more than 200 prostate cancer patients. Scientists Confirm That People do Actually Age at Different Rates. When you turn up at your high school reunion and look around, you might notice something.
Despite all of you being born within one year of each other, some will almost certainly look younger and some older. Indeed, a recent study published in the Proceedings of the National Academy of Sciences has confirmed what many have already observed: People do actually age at a different rate – and some of us much more dramatically than others. While most people in the study had a biological age close to the 38 birthdays they’d racked up, some were significantly younger or older, reflected in the state of their organs, metabolism and mental abilities.
The researchers from Duke University followed 1,000 people who were born in the same town in the same year, and checked up on them when they were 26, then 32, and finally when they hit 38 years old. Out of the original group enrolled, 30 died before they had reached 38 due to a range of problems, from diseases such as cancer to accidents or suicide.
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. "There is a longstanding association between wound healing and cancer, with cancer often described as a 'wound that does not heal,'" said Dr. 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.
That such vessels could have escaped detection when the lymphatic system has been so thoroughly mapped throughout the body is surprising on its own, but the true significance of the discovery lies in the effects it could have on the study and treatment of neurological diseases ranging from autism to Alzheimer’s disease to multiple sclerosis. 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. 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.

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. The association between discontinuing hormonal contraceptives and wives’ marital satisfaction depends on husbands’ facial attractiveness. Author Affiliations Edited by Steven J. C. Gaulin, University of California, Santa Barbara, CA, and accepted by the Editorial Board October 16, 2014 (received for review August 1, 2014) Significance. Researchers make blood vessels grow by shining a light on skin. Any fan of Star Trek knows that simply shining light on an injury will heal many wounds in the future. Now scientists have brought that future a bit closer. In a new study, researchers have found a way to stimulate the growth of blood vessels—an important part of healing—by hitting the skin with ultraviolet light. In the past decade, scientists have used light to manipulate the chemistry of cells in a dish—but they’ve struggled to do the same in living organisms.
“There are hundreds of different types of cells; you have a lot more other biological molecules present,” says bioengineer Andrés García of the Georgia Institute of Technology in Atlanta. So García and colleagues turned to a water-based gel, or hydrogel, impregnated with a molecule called RGD peptide. 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. Desprez, a molecular biologist, spent decades studying ID-1, the gene that causes cancer to spread. Meanwhile, fellow researcher Sean McAllister was studying the effects of Cannabidiol, or CBD, a non-toxic, non-psychoactive chemical compound found in the cannabis plant. Paul Ryan’s budget flimflam. By Editorial Board October 1, 2012. 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. 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. Greek police send crime victims to neo-Nazi 'protectors' Greece's far-right Golden Dawn party is increasingly assuming the role of law enforcement officers on the streets of the bankrupt country, with mounting evidence that Athenians are being openly directed by police to seek help from the neo-Nazi group, analysts, activists and lawyers say.
