Despite caffeine's many benefits, there's a belief out there that a daily coffee habit can cause dehydration. So is it true? Not according to the findings of a new study.

Psychedelics could be 'next generation' of safer treatments for mental health

It’d be great if a burger-a-day diet was healthy. Don’t get me wrong—it’s not the worst. You’ve got protein in there and hopefully some veggies on top (and on the side) , and even some fiber from the roll (you used whole grain, right?). Unfortunately, study after study shows that meat as a protein source just isn’t that healthy. It’s far better to get that necessary protein from plants. But why?

We take a fair look at some of the best counter arguments for legalization and see how they hold up in review.

Your genes can determine whether you're a morning person or night owl.

Eating disorders can be difficult to treat. And recovery is often a long road. But how are EDs like anorexia nervosa, bulimia nervosa, and binge eating disorder treated? And why is recovering from it so tough? We'll explore the mental health side of common eating disorders and shed some light on how therapy can help.

A billionaire and his very powerful computer are helping a pharma pioneer find the drugs of tomorrow.

Over the ages our teeth and our tongue have become ever more crowded by the shrinking of the human jaw.

One of the things we learned during David Rubenstein’s interview of Tim Cook, posted in full yesterday, was that all employees at Apple Park are getting standing desks. The desks allow employees to switch between sitting and standing. As Business Insider notes, Cook has previously described sitting as ‘the new cancer.’ He made the comment back in 2015 when talking about the stand reminders on the Apple Watch.

Every year, the state of Illinois struggles to find a place for hundreds of children with serious mental-health issues—holding them in psychiatric hospitals for sometimes weeks or months even after they're cleared for discharge.

The World Health Organization (WHO) today certified Paraguay as having eliminated malaria, the first country in the Americas to be granted this status since Cuba in 1973. “It gives me great pleasure today to certify that Paraguay is officially free of malaria,” said Dr Tedros Adhanom Ghebreyesus, WHO Director General, in a recorded statement. “Success stories like Paraguay’s show what is possible. If malaria can be eliminated in one country, it can be eliminated in all countries.”

A Chicago-based duo is selling a simple strategy — and companies they’ve worked with have raised prices on drugs as much as 4,116%.

After prenatal testing shows a fetus is at risk, families are faced with a profound decision. The national abortion debate is making it harder on them.

Alzheimer's drug development tends to focus on protein aggregates in the brain. Perhaps that's why they've all failed.

A new review of 180 studies found little or no protective effects from taking dietary supplements, and actually found some harm.

Poop studies are helping communities make intervention decisions

President Donald Trump on Wednesday signed a bill that will allow terminally ill patients to request experimental drugs that the Food and Drug Administration has not yet approved. "Our implementation of the Right to Try Act will build on our long-standing efforts to help patients and families who are facing life-threatening diseases or conditions, in a way that seeks to protect their autonomy, their safety, and the safety of others following in their paths," FDA Commissioner Scott Gottlieb said in a statement.

England has continued to see a rise in cases of syphilis and gonorrhoea over the past year. New data shows a 20% increase in cases of syphilis and a 22% increase in gonorrhoea, compared with 2016. Diagnoses of sexually transmitted infections (STIs) in England remain stable overall, with around the same number reported as the previous year. Health experts have expressed concern over a decline in testing for chlamydia.

Can probiotics fend off mood disorders? It's too early to say with scientific certainty, but a new study by University of Colorado Boulder researchers suggests that one particular beneficial bacteria can have long-lasting anti-inflammatory effects on the brain, making it more resilient to the physical and behavioral effects of stress. The findings, if replicated in clinical trials could ultimately lead to new probiotic-based immunizations to protect against posttraumatic stress disorder (PTSD) and anxiety or new treatments for depression, the authors say.

Many doctors in the U.S. say the practice puts an infant at risk of sleep-related death. A close look at the research reveals a different picture.

A new study found those who reported walking faster were less likely to die prematurely.

Ask just about anybody, and you'll probably hear that a healthy diet is one full of fruits and vegetables, olive oil, nuts and fish — what's called Mediterranean diet. A lot of research has suggested people who eat this way tend to be healthier, but it's been harder to prove whether that is because of the diet or some other factor.

HIV patients on a single-tablet daily regimen had better outcomes than patients taking multiple pills per day, a new study shows.

Clean modern homes, antiseptic wipes and the understandable desire to protect small babies against any infection are all part of the cause of the most common form of childhood cancer, a leading expert has concluded after more than 30 years of research. Childhood acute leukaemia, says the highly respected Prof Mel Greaves, is nothing to do with power lines or nuclear fuel reprocessing stations. Nor is it to do with hot dogs and hamburgers or the Vatican radio mast, as have also been suggested.

The U.S. death rate rose last year, and 2017 likely will mark the third straight year of decline in American life expectancy, according to preliminary data. Death rates rose for Alzheimer's disease, diabetes, flu and pneumonia, and three other leading causes of death, according to numbers posted online Wednesday by the Centers for Disease Control and Prevention. Full-year data is not yet available for drug overdoses, suicides or firearm deaths. But partial-year statistics in those categories showed continuing increases.

Wealth and health are intrinsically linked in the United States, with rich Americans living between 10 to 15 years longer than their poor counterparts, a study has found. A series of five papers published in the medical journal The Lancet found that a widening income gap, structural racism and mass incarceration are fueling growing health inequalities. “The USA is one of the richest countries in the world, but that reality means very little for most people because so much of that wealth...

The F.D.A. banned the use of antibiotics for growth promotion in animals last year. One organic cattle farmer is sure the ban is being flouted.

Disruption to the body clock increases the risk of mood disorders and depression, a large study has confirmed. Scientists at the University of Glasgow looked at the circadian rhythms - which control functions including sleep patterns, body temperature, our immune systems and the release of hormones - of more than 90,000 people to measure daily rest-activity rhythms, called relative amplitude.

The illnesses in China have broadened a crisis that started in 2016, when American Embassy employees and their family members in Cuba began getting sick after hearing strange noises.
