Anorexia stems from body as well as mind – study - BBC News
The origins of the eating disorder anorexia nervosa are in both the mind and the body, according to an international study.

Anorexia is seen as a serious psychiatric disease.

But doctors at King's College London showed changes hardwired into some people's DNA altered the way they processed fats and sugars and may make it easier to starve their bodies.

The eating disorder charity Beat said the findings were groundbreaking.

The researchers looked at 16,992 people with anorexia and 55,525 people without the disease, from 17 countries.

All their DNA - the blueprint for the human body - was analysed to find mutations in genetic instructions that were more common in anorexia patients.

The study, published in Nature Genetics, found some mutations also presented in other psychiatric disorders such obsessive-compulsive disorder, anxiety, and schizophrenia.

But they also found mutations in the instructions that control the body's metabolism, particularly those involving blood sugar levels and body fat.

"There is something in those systems that has gone awry," Prof Janet Treasure, from the Institute of Psychiatry at King's College London, told BBC News.

The researchers - at King's and the University of North Carolina at Chapel Hill - say anorexia should now be considered a "metabo-psychiatric disorder" as it is a disease of mind and body.

Breast cancer gene mutation 'doesn't affect survival' - BBC News
About a third of those with the BRCA mutation had a double mastectomy to remove both breasts. This surgery did not appear to improve their chances of survival at the 10-year mark. [...] Fiona MacNeill, of the Royal Marsden NHS Foundation Trust, who was not involved in the research, said: "This study can reassure young women with breast cancer, particularly those with triple negative cancer or who are BRCA carriers, that breast conservation with radiotherapy is a safe option in the first decade after diagnosis and double mastectomy is not essential or mandatory at initial treatment.

She added: "In view of this, younger women with breast cancer can take time to discuss whether radical breast surgery is the right choice for them as part of a longer-term risk reducing strategy." &! &!

Internal 'clock' makes some people age faster and die younger – regardless of lifestyle | Science | The Guardian
Scientists have found the most definitive evidence yet that some people are destined to age quicker and die younger than others - regardless of their lifestyle.

The findings could explain the seemingly random and unfair way that death is sometimes dealt out, and raise the intriguing future possibility of being able to extend the natural human lifespan.

“You get people who are vegan, sleep 10 hours a day, have a low-stress job, and still end up dying young,” said Steve Horvath, a biostatistician who led the research at the University of California, Los Angeles. “We’ve shown some people have a faster innate ageing rate.”

'Superhero DNA' keeps diseases at bay
Large numbers of studies have tried to understand these mutations by looking at people who become ill.
But the international team of researchers tried the opposite approach - searching for people harbouring damaging mutations but who remain healthy. [...] "Study the healthy, don't just study the sick."
However, this is where the tantalising story ends. The scientists were unable to go out and find the lucky 13 because of the consent rules signed when their DNA sample was taken.
It means they do not know what is protecting them against disease. [...] "Because of the inability to confirm the source or validity of the variants and the inability to recontact the individuals, this paper does not constitute a proof of principle," [ means they have to do a large-scale study especially for this kind of research ]

Stem cells 'link' to repeat miscarriages, say scientists - BBC News
[ is this a western phenomenon? sick population? not africa, not some parts of japan? ] Accelerated ageing "In fact, this may be the only way to really prevent miscarriages in these cases." The team found a shortfall of stem cells was the likely cause of accelerated ageing of the womb lining which resulted in the failure of some pregnancies. The lining has to renew itself each cycle and this renewal capacity is dependent on the resident stem cell population. Prof Brosens said: "Cultured cells from women who had had three or more consecutive miscarriages showed that ageing cells in the lining of the womb don't have the ability to prepare adequately for pregnancy." [...] "The real challenge now is to develop strategies to increase the function of stem cells in the womb lining," she said. The team will soon start piloting new interventions to improve the womb lining, she said. [ diet and lifestyle? ]

Scientists get 'gene editing' go-ahead - BBC News
UK scientists have been given the go-ahead by the fertility regulator to genetically modify human embryos. It is the first time a country has considered the DNA-altering technique in embryos and approved it. The research will take place at the Francis Crick Institute in London and aims to provide a deeper understanding of the earliest moments of human life. It will be illegal for the scientists to implant the modified embryos into a woman. But the field is attracting controversy over concerns it is opening the door to designer - or GM - babies.

Hawking: Humans at risk of lethal 'own goal' - BBC News
Humanity is at risk from a series of dangers of our own making, according to Prof Stephen Hawking. Nuclear war, global warming and genetically-engineered viruses are among the scenarios which he singles out. And he says that further progress in science and technology will create "new ways things can go wrong". Prof Hawking is giving this year's BBC Reith Lectures, which explore research into black holes, and his warning came in answer to audience questions. He says that assuming humanity eventually establishes colonies on other worlds, it will be able to survive. "Although the chance of a disaster to planet Earth in a given year may be quite low, it adds up over time, and becomes a near certainty in the next thousand or ten thousand years. [...] But he also said that future generations of researchers should be aware of how scientific and technological progress is changing the world, and to help the wider public understand it. //&!

Age of menopause 'controllers' found - BBC News
Damage corrected. Comparing the DNA of nearly 70,000 women allowed the researchers to identify the differences between those starting the menopause early and late. The team at Exeter and Cambridge universities showed that at least two repair mechanisms were involved. The first is used when the eggs are being formed and the woman's DNA is being broken, rearranged and repaired. The second corrects damage, caused by factors such as smoking or alcohol, throughout a woman's life. Both would influence the number of viable eggs a woman has. //&!

Rare 'healthy' smokers' lungs explained - BBC News
The analysis of more than 50,000 people showed favourable mutations in people's DNA enhanced lung function and masked the deadly impact of smoking. The Medical Research Council scientists say the findings could lead to new drugs to improve lung function. But not smoking will always be the best option, they say. [...] The habit also increases the risk of heart disease and cancers, which are not considered in this study. The scientists also uncovered parts of the genetic code which were more common in smokers than non-smokers. They seem to alter the brain's function and how easily someone can become addicted to nicotine, although that still needs to be confirmed.

Genetic clue to breast cancer relapses - BBC News
A research team from the Wellcome Trust Sanger Institute in Cambridge found that cancers that return were more likely to contain certain genes or combinations of genes. Targeting these genes with early treatments could be key, they said. The study is being presented at the European Cancer Congress in Vienna. In around one in five people with breast cancer, the disease will return - either to the same place as the original tumour or another part of the body.

The sensationalist assertions made in this article (particularly in the headline) don't follow from the results that the article describes. Part of the blame for this sensationalism seems to fall at the feet of the original scientist himself (Bosch). He makes an unfounded leap from the biological result that cancer seems to be an intrinsic property of genetic processes in cells (and the statements "You have to interfere with fundamental pathways", "It's a web of interactions" and "It's very difficult to do") to the assertion "will probably never be completely eradicated". Difficult is not the same as impossible. ||>> how we eat, how active we are, and our living environment (pollution and stress) is itself a multiplying factor whether or not we die of old age or of cancer or bc of complications of toxic medical cancer treatment.

With Gene Disorders, The Mother's Age Matters, Not The Egg's : Shots - Health News : NPR
So then why does the risk of birth defects increase as women get older? It's more likely that there's no one maternal-age effect on eggs, Rowsey says. "There are many different factors that come into play, and we have to explain them all." The proteins that bind chromosomes together may degrade over the years that the egg is waiting in a woman's ovary, Rowsey says. The number of eggs that women have is also depleted over time, so there might be fewer good ones to choose from. Whatever the causes, the maternal-age effect is undeniable. "The rate of chromosomal abnormality appears to be hard-wired into our species," says Hassold. "The only thing that moves the dial is maternal age."

Low Vitamin D Levels Linked to Disease in Two Big Studies -
Vitamin D helps the body absorb calcium and is an important part of the immune system. Receptors for the vitamin and related enzymes are found throughout cells and tissues of the body, suggesting it may be vital to many physiological functions, said Dr. Oscar H. Franco, a professor of preventive medicine at Erasmus Medical Center in the Netherlands and an author of one of the new studies, which appeared in the journal BMJ. “It has effects at the genetic level, and it affects cardiovascular health and bone health,” he said. “There are different hypotheses for the factors that vitamin D regulates, from genes to inflammation. That’s the reason vitamin D seems so promising.”

Alter des Vaters ist ein Risikofaktor für psychische Störungen - SPIEGEL ONLINE
Aus medizinischer Sicht kann die insgesamt etwas spätere Familiengründung Risiken bergen, das legten schon mehrere Studien nahe. Experten vermuten, dass die Spermien der Männer mit zunehmendem Alter mehr Mutationen im Erbgut enthalten - darunter eben auch schädliche. Jetzt präsentieren Forscher aus Schweden und den USA im Fachjournal "Jama Psychiatry" eine weitere Studie, die zeigt: Das Risiko für verschiedene psychische Störungen, darunter ADHS, Autismus und Psychosen, nimmt mit steigendem Alter des Vaters zu. [...] Gleichwohl waren die Wissenschaftler über die deutlichen Effekte erstaunt. "Wir waren erschüttert von den Ergebnissen", sagt D'Onofrio. "Die Zusammenhänge mit dem Alter des Vaters waren viel, viel größer als in früheren Studien." Auch wenn natürlich viele Kinder älterer Väter überhaupt nicht mit den beschriebenen Problemen zu kämpfen hätten, sei es doch wichtig, über die möglichen Risiken aufzuklären.

Alcoholism Through a Doctor's Eyes -
These reactions still occur, even though scientists have recently identified a genetic component to alcoholism. According to the National Institute on Alcohol Abuse and Alcoholism, there are a series of genes that are responsible for roughly half the risk of someone becoming an alcoholic. Another facet of alcoholism that remains familiar is the lack of good treatment options. Detoxification and rehabilitation programs are expensive and not that effective. And while new research suggests that drugs can be used to facilitate drinking in moderation, I still refer the vast majority of my alcoholic patients to A.A., just as other doctors did 80 years ago. Yet even A.A.’s ability to maintain ongoing sobriety among its participants is only about 10 percent, although certain populations, with stronger social supports, do better.

Smart Teenage Brains May Get Some Extra Learning Time : Shots - Health News : NPR
Hewitt and Brant don't know why some teenagers continue to learn at the pace of much younger children. It may be that smart kids gravitate to challenging activities and this keeps them receptive to learning. Or it could be that genes that lead to high IQ also trigger an extended learning period. [...] The study, published in Psychological Science, suggests that for many children it may be a mistake to stop learning new things. Even if you're a teenager, it might not be too late to start learning Chinese, chess or the cello.

The hits come quickly: "You're disgusting." [Scroll.] "Ur a man." [Scroll.] "What are you? #man? #ape?"..."Here's one," she says, rolling her eyes. "'You have a penis.'" Satisfied that her troll chorus still cares, Griner puts away the phone. "Reading what people say makes me want to be me even more."

Seeking Clues to a Heart Killer in the DNA Binding a Family -
Researchers have long known that a family history of early death from heart disease doubles a person’s risk independently of any other factors. Family history is defined as having a father or a brother who were given a diagnosis of heart disease before age 55 or a mother or sister before age 65.

Wie sich Fett auf den Stoffwechsel und die Gene auswirkt - SPIEGEL ONLINE
Fett zaubert nicht nur Polster auf die Hüften, es verändert auch Gene und Stoffwechsel. Forscher haben jetzt im Detail beobachtet, wie sich eine fettreiche Ernährung auf den Körper auswirkt. Demnach erhöht der Energieträger nicht nur Blutdruck und Hunger, sondern schraubt auch am Tag-Nacht-Rhythmus. >> Low-Fat (No Oil) Vegan Diet <<

Why Fathers Really Matter -
Doctors have been telling men for years that smoking, drinking and recreational drugs can lower the quality of their sperm. What doctors should probably add is that the health of unborn children can be affected by what and how much men eat; the toxins they absorb; the traumas they endure; their poverty or powerlessness; and their age at the time of conception. In other words, what a man needs to know is that his life experience leaves biological traces on his children. Even more astonishingly, those children may pass those traces along to their children.

[...] Genes matter, and culture matters, and how fathers behave matters, too.

**A certain lifestyle and environment switches on/off certain genes and functions - point in time information - that gets carried on to the baby.**

[...] Our genes can be switched on or off by three environmental factors, among other things: what we ingest (food, drink, air, toxins); what we experience (stress, trauma); and how long we live.

BBC News - Gene flaw 'explains why drugs failed to treat MS'
"The effects of genetic variants influencing disease risk or resistance can be amplified by drugs. This has often been completely overlooked, but will be critical for using genetic findings in a medical context."

"This important study has shown that some of your genes can play a part in deciding whether or not you respond to a treatment.

Popeye had the right idea as favourite snack spinach could cut colon cancer | Mail Online
Researchers at Oregon State University found eating the green leafy vegetable reduced the damaging effects of a carcinogen found in cooked meat.
They were studying the complex biological effects of the cancer-causing substance on microRNA and cancer stem cells.
During their animal study they found that the consumption of spinach could partially offset the damaging effects of the carcinogen. In tests with laboratory animals, it cut the incidence of colon tumors almost in half, from 58 per cent to 32 per cent.
'Cancer development is a complex, multi-step process, with damaged cells arising through various means,'

increasing interest in the role played by epigenetics, in which such factors as diet, environmental toxins, and lifestyle affect the expression of genes – not just in cancer, but also cardiovascular disease, diabetes, and neurological disorders.

Cancer and epigenetics: Cancer’s epicentre | The Economist
Cancer ...
Sometimes the genetic flaw is inherited. Sometimes it is the result of exposure to an outside agent such as tobacco smoke or radioactivity. Sometimes it is plain bad luck; a miscopying of a piece of DNA during the normal process of cell division.

No one has worked out how to repair DNA directly. It is, rather, a question of discovering the biochemical consequences of the genetic damage and trying to deal with those instead. But recently, another pattern has emerged. It is too early to call it a breakthrough as significant as the cancer-is-caused-by-broken-genes finding, but it might be.

Epigenetics, switches genes on and off by plastering either their DNA or the proteins which support that DNA in chromosomes with clusters of atoms called methyl and acetyl groups.

Epigenetic processes are susceptible to chemical intervention in a way that genetic mutations are not.

Epigenetics might justly take its place alongside genetics in the analysis and treatment of cancer.

Birth Control Pills Have Lasting Effects on Relationships: Scientific American
hormonal birth control pill does affect your taste of men.

This relationship stability might be caused by the bias of women on the pill toward low-testosterone men, who tend to be more faithful. Roberts suggests that women who met their mate while taking the pill might want to switch to nonhormonal contraceptives several months before getting married to test whether their feelings for their partner remain the same.

Shortcuts - In Talent, Determination Outweighs Nature and Nurture -
Most of us think of talent as an ability we’re born with and have fairly little control over. But increasingly, experts are questioning the notion that genes limit how far we can go.

Counsyl Brings Genetic Screening to the Masses -
Now, a Silicon Valley start-up is making the bold claim that it can help eradicate that disease and more than 100 others by alerting parents-to-be who have the carrier genes.

The company, Counsyl, is selling a test that it says can tell couples whether they are at risk of having children with a range of inherited diseases, including cystic fibrosis, Tay-Sachs, spinal muscular atrophy, sickle cell disease and Pompe disease (the one afflicting the children in the movie).
