Researchers uncover possible source of genetic error causing multiple diseases. Can your biome make you fat? Emily Pidgeon/TED Is there a correlation between your biome and your BMI?
In her new book, Why Diets Make Us Fat, neuroscientist Sandra Aamodt sheds light on this tangled, cryptic relationship. There seems to be little doubt that the diet book of 2016 is Sandra Aamodt’s Why Diets Make Us Fat: The Unintended Consequences of Our Obsession with Weight Loss — it’s already been a cover story in the New York Times Sunday Review. But more significantly, Aamodt’s book lays waste to the diet-book field — and indeed the entire dieting field — with the radical assertion that it is, in fact, exactly the kind of weight loss generated by diets that prompt your body to regain the weight lost — whether you want to or not. (For example, your body’s metabolism drops precipitously after weight loss, meaning you have to eat much, much less than you did when you were dieting in order to keep it off.)
The science world is freaking out over this 25-year-old's answer to antibiotic resistance. A 25-year-old student has just come up with a way to fight drug-resistant superbugs without antibiotics.
The new approach has so far only been tested in the lab and on mice, but it could offer a potential solution to antibiotic resistance, which is now getting so bad that the United Nations recently declared it a "fundamental threat" to global health. Antibiotic-resistant bacteria already kill around 700,000 people each year, but a recent study suggests that number could rise to around 10 million by 2050. Stoned Lab Rats Become Too Lazy For Tests, Study Finds. With an increasing number of US states and countries around the world relaxing their laws on medical and recreational marijuana, the need to rigorously study the biological effects of smoking weed becomes ever more pressing.
Many of these trials and experiments are conducted on lab rats, the latest of which has revealed that the rodents tend to become too lazy to bother with difficult cognitive tests when they are stoned. Appearing in the Journal of Psychiatry and Neuroscience, the study sought to determine how two of marijuana’s main ingredients, namely tetrahydrocannabinol (THC) and cannabidiol (CBD), affect laziness levels. A prospective study of meat and meat mutagens and prostate cancer risk. Mayo Clinic researchers draw connection between microbiome and cancer from the same human breast tissue. The diverse community of bacteria that coexist in the human body has recently garnered great interest in medicine.
For example, microorganisms found in the gut (also known as the gut microbiota) have been linked to inflammation and metabolic syndrome as well as other diseases. Columbia researchers find biological explanation for wheat sensitivity. NEW YORK, NY (July 26, 2016)--A new study may explain why people who do not have celiac disease or wheat allergy nevertheless experience a variety of gastrointestinal and extra-intestinal symptoms after ingesting wheat and related cereals.
The findings suggest that these individuals have a weakened intestinal barrier, which leads to a body-wide inflammatory immune response. Findings from the study, which was led by researchers from Columbia University Medical Center (CUMC), were reported in the journal Gut. Maple Syrup Protects Neurons and Young Minds. Catherine Aaron and Gabrielle Beaudry were 17 when they knocked on the door of the laboratory of Alex Parker, a neuroscience researcher at the University of Montreal Hospital Research Centre (CRCHUM).
While students at Collège Jean-de-Brébeuf in Montreal, they were looking for a mentor for an after-school research project. Two and half years later, the results of this scientific adventure were published today in the Journal of Agricultural and Food Chemistry. "We wanted to test the effect of a natural product on a neurodegenerative disease such as Alzheimer's. Laser Tooth Regeneration - Hashem Al-Ghaili. Starting work before 10 a.m. is tantamount to torture and is making staff sick and stressed: researcher. Forcing staff to start work before 10 a.m. is tantamount to torture and is making employees ill, exhausted and stressed, an Oxford University researcher has claimed.
Before the age of 55, the circadian rhythms of adults are completely out of sync with normal nine-to-five working hours, posing a “serious threat” to performance, mood and mental health. Dr. Paul Kelley, of Oxford University, said there was a need for a huge societal change to move work and school starting times to fit with the natural body clock of humans. Parasite Infection Linked to Road Rage. People who display frequent bouts of extreme, impulsive anger, such as road rage, are more than twice as likely to be infected with a common parasite than are individuals who do not exhibit such explosive behavior, according to a new study.
The findings, reported in the Journal of Clinical Psychiatry, suggest that the parasitic infection toxoplasmosis could lead to increased aggressiveness and associated mental illness in some people. People who repeatedly fly off the handle with little provocation and who overreact to stress are often diagnosed with a condition known as intermittent explosive disorder. Top 10 Oldest Insects, Spiders and Bugs “Our work suggests that latent infection with the Toxoplasma gondii parasite may change brain chemistry in a fashion that increases the risk of aggressive behavior,” senior author Emil Coccaro of the University of Chicago said in a press release. Parasite Brainwashes Mice to Not Fear Cats. 19 Pieces Of Non-Human DNA Found In Human Genome. Eight percent of your DNA is alien, in that it’s made up of non-human, viral fragments.
In fact, viral fragments are often hiding within the genome of anything on Earth that has a jaw and a spinal cord, which is a remarkable reminder of how they’ve shaped evolution for hundreds of millions of years. A new study, published in the Proceedings of the National Academy of Sciences, reveals that we are even less “human” than previously thought: Nineteen new pieces of ancient viral DNA have been uncovered within our own genome. Perhaps most strikingly, the full genetic “recipe” for an entire virus was found within 2 percent of the people examined.
Retroviruses of all kinds have their genetic code in the form of RNA, often seen as the primitive precursor to DNA. Scientists Discover a Way to Annihilate Every Cell in a Cancerous Tumor — NOVA Next. Immunotherapy’s promise as a cancer therapy is undeniable, yet current treatments only work for some types of cancers.
What’s more, it works in only about 20% of patients. But if the results of a new study translate into viable treatments, those statistics may soon change. When cancer strikes, our immune systems produce T-cells that recognize neoantigens—molecules on the surface of tumor cells—and attack anything in sight that carries them. Drugs that target specific mutations can boost this response, but the surface of cancer cells can vary greatly, even within the same tumor. Moments of joy 'can damage heart' Image copyright Thinkstock The emotional stress that causes chest pains and breathlessness can occur in moments of joy as well as anger, grief and fear, a Swiss study suggests.
Three-quarters of cases of takotsubo cardiomyopathy, a change in the shape of the heart's left ventricle, which can be fatal, are caused by stress. The University Hospital Zurich study, in the European Heart Journal, suggests about one in 20 cases is caused by joy. The condition is normally temporary and people are generally fine afterwards. In the study of 1,750 patients, researchers discovered heart problems caused by:
Science Says Cheese is Basically Cocaine. You know how it is: You're bored at some fancypants dinner party, so you meander over to the snack table and think, "Cool, they have cheese," and then, "Whoa, that cheese is tasty, I should have another few blocks," and then 10 minutes later you're smearing cheese all over your nose and jumping over coffee tables while shouting about how you're the god of thunder? Well FINALLY science has taken a break from proving Earth's spherical shape to B.o.B to afford us an explanation: Turns out cheese triggers the same excitable brain-parts as some of your favorite hard drugs! So the opposite is probably also theoretically true, which will help explain if you've ever been like, "This meth is good, but what I'd really love is some lasagna.
" The study, researched at the University of Michigan (seriously how did the University of Wisconsin get scooped on this) and published in the U.S. National Library of Medicine, investigated why some foods cause addictive behaviors and other foods are lentils. Birth of a microbiome: Researchers smear babies with vaginal fluid. Birth, like life, is messy. But, while life’s messes often harm health, the untidiness of our entrance into the world may profoundly protect it—at least that’s a leading hypothesis among microbiome researchers. Microbes picked up from mom while in or exiting the womb kick off humans’ lifelong association with the invisible critters that live in and on us and affect our health. The latest study about antioxidants is terrifying. Scientists think they may boost cancer cells to spread faster. Blueberries have been marketed as a superfood and one of nature's most potent antioxidants. (iStock) Since the term "antioxidants" made the leap from the realm of biochemistry labs and into the public consciousness in the 1990s, Americans have come to believe that more is better when it comes to consuming the substance that comes in things like acai berries, green tea and leafy veggies.
A provocative new study published Wednesday in the journal Nature raises important questions about that assumption. Gut neurons help prevent tissue over-inflammation. Malaria vaccine provides hope for a general cure for cancer. 13 October 2015. Wasp venom 'a weapon against cancer' The venom of a wasp native to Brazil could be used as a weapon to fight cancer, scientists believe. A toxin in the sting kills cancer cells without harming normal cells, lab studies suggest. The University of Brazil team say the experimental therapy latches to tumour cells and makes them leak vital molecules.
Newly Discovered Enzyme Prevents Sugar Being Stored As Fat. Common painkiller may also be powerful cancer killer. WASHINGTON, Jan. 12 (UPI) -- The painkiller diclofenac, a common painkiller used to treat migraine, fever and rheumatoid arthritis, may hold significant anti-cancer properties, according to new research. Sugary Drink Intake Tied to Belly Fat. Action Points Drinking sugary sodas was associated with more fat around the belly.Note that there was no association between visceral fat and diet soda. Drinking sugary sodas was associated with more fat around the belly, according to a new analysis of the Framingham Heart Study.
Based on measurements of visceral adipose tissue and subcutaneous adipose tissue in more than 1,000 middle-aged adults, higher intake of sugar-sweetened beverages, as reported at baseline, was associated with a greater change in visceral adipose tissue volume over 6 years (P<0.001 for trend), according to Caroline Fox, MD, MPH, of the National Heart, Lung, and Blood Institute (NHLBI) in Framingham, Mass., and colleagues. Most cases of cancer are avoidable, say researchers. Most cases of cancer result from avoidable factors such as toxic chemicals and radiation, according to a study. Scientists Have Discovered "Clocks" Inside Your Cells That Could Determine When You Get Cancer. External factors like the Sun and smoking can harm your DNA by causing mutations, a process that occurs in spurts and bursts. But this process isn't limited to environmental triggers: As cells grow and divide, internal factors also cause the cell to continuously generate mutations at a constant rate.
