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.

Starting work before 10 a.m. is tantamount to torture and is making staff sick and stressed: researcher

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. Experiments studying circadian rhythms have shown that the average 10-year-old will not fully focus on academic work before 8.30 a.m.

Similarly, a 16-year-old should start at 10 a.m. for best results and university students should start at 11 a.m. Similarly, companies who force employees to start work earlier are likely to be hurting their output, while storing up health problems. “This is a huge society issue,” Dr. 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.

Parasite Infection Linked to Road Rage

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. 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.

These viruses infect their host cells by inserting a DNA-based replica of their own RNA into the genome of their host, which can include humans. 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.

Scientists Discover a Way to Annihilate Every Cell in a Cancerous Tumor — NOVA Next

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. 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.

Moments of joy 'can damage heart'

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?

Science Says Cheese is Basically Cocaine

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.

Birth of a microbiome: Researchers smear babies with vaginal fluid

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. 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.

The latest study about antioxidants is terrifying. Scientists think they may boost cancer cells to spread faster.

(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. Antioxidants — which include vitamins C and E and beta-carotene, and are contained in thousands of foods — are thought to protect cells from damage by acting as defenders against something called "free radicals" which the body produces as a part of metabolism or that can enter through the environment. Gut neurons help prevent tissue over-inflammation. The researchers say they now have a much better idea of how neurons and macrophages in the gut work together to help prevent damage from inflammation.

Gut neurons help prevent tissue over-inflammation

Now, a new study - by researchers at Rockefeller University, New York, NY, and published in Cell - shows that neurons in the gut appear to work with cells of the immune system to fine-tune this balance and prevent over-inflammation of intestinal tissue. Senior author Daniel Mucida, an assistant professor and head of Rockefeller's mucosal immunology lab, says: "Resistance to infections needs to be coupled with tolerance to the delicacy of the system. Our work identifies a mechanism by which neurons work with immune cells to help intestinal tissue respond to perturbations without going too far. " He and his colleagues believe their findings could help develop new treatments for gastrointestinal diseases, such as irritable bowel syndrome (IBS). Prof. Malaria vaccine provides hope for a general cure for cancer.

13 October 2015 The hunt for a vaccine against malaria in pregnant women has provided an unexpected side benefit for Danish researchers, namely what appears to be an effective weapon against cancer.

Malaria vaccine provides hope for a general cure for cancer

The scientists behind the vaccine aim for tests on humans within four years. Danish scientists from the University of Copenhagen and the University of British Columbia (UBC) face a possible breakthrough in the fight against cancer, which may result in a genuine medical treatment for the dreaded disease. The hunt for a weapon to fight malaria in pregnant women has revealed that, expressed in popular terms, armed malaria proteins can kill cancer. 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.

Wasp venom 'a weapon against cancer'

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. The work is at an early stage and more studies are needed to check the method will work safely in humans. Newly Discovered Enzyme Prevents Sugar Being Stored As Fat.

It’s January, and many of you are likely scrambling to pick a diet in an attempt to lose some of the post-Christmas weight gain. Your body's conversion of all the excess sugar consumed into fat certainly didn't help, but a team of researchers from the University of Montreal may have found a way to regulate this. As reported in Proceedings of the National Academy of Sciences, a new enzyme has been discovered that can directly control how your body converts sugar and fats. Mammalian cells use both sugar (glucose) and fatty acids as their main sources of energy. Much of this glucose is stored in the liver as glycogen, a dense compound that can be mobilized whenever the body requires it for energy production. Those in developed countries tend to have diets that are too sugar-rich, giving themselves far more glucose than their body needs at the time. Insulin, a hormone produced by the pancreatic beta cells, causes the liver to convert glucose into glycogen.

Photo Gallery. 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. Diclofenac is a non-steroidal anti-inflammatory drug, or NSAID, a type of painkiller that has shown promise to prevent cancer, however researchers in Belgium and the United States report the drug could play an important role in treating cancer based on previous studies and in-progress clinical trials. The drug, sold as Voltaren, Zipsor, Solaraze, and Cambia, among other names, is cheap and widely available. Researchers said excitement over the drug's potential use for cancer is based on its effects on the immune system and on angiogenesis, the development of blood vessels that move oxygen and nutrients to tissues.

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. They noted that visceral adipose tissue volume increased differently depending on how much soda the participant consumed: "The present study supports current dietary recommendations that limiting SSB consumption may be helpful to prevent cardiometabolic diseases," the authors stated.

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. The findings clash with research published earlier this year which found that differences in cellular processes were the chief reason some tissues became cancerous more frequently than others. 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.
