Because it tastes so good, you may assume coffee is bad for you. Maybe you’ve heard rumors that your morning brew causes everything from heart disease to cancer. But researchers are finding that coffee poses little to no health risk for most people. Not only that, coffee drinking might have some health benefits.

Alzheimer's disease is an age-related, non-reversible brain disorder that develops over a period of years. Initially, people experience memory loss and confusion, which may be mistaken for the kinds of memory changes that are sometimes associated with normal aging.

There are four types of headache: vascular, muscle contraction (tension), traction, and inflammatory. The most common type of vascular headache is migraine. Migraine headaches are usually characterized by severe pain on one or both sides of the head, an upset stomach, and, at times, disturbed vision.

An aneurysm—a balloon-like bulge in an artery—can develop and grow for years without causing any symptoms. But an aneurysm is a silent threat to your health. Many aneurysms occur in deep inside the chest, abdomen or brain. Most appear in the aorta—the main artery that carries blood from the heart down through the center of the body.

Osteoporosis, or porous bone, is a disease characterized by low bone mass and structural deterioration of bone tissue, leading to bone fragility and an increased risk of fractures of the hip, spine, and wrist. Men as well as women are affected by osteoporosis. You can't "catch" osteoporosis or give it to someone else. Osteoporosis can be prevented and treated.

Treatment for back pain generally depends on what kind of pain you experience: acute or chronic.

It is important to understand that back pain is a symptom of a medical condition, not a diagnosis itself. Medical problems that can cause back pain include the following: mechanical problems, injuries, acquired conditions and diseases, infections and tumors.

Although anyone can have back pain, a number of factors increase your risk. They include: age, fitness level, diet, heredity, race, the presence of other diseases, occupational risk factors, cigarette smoking.

At some point, back pain affects an estimated 8 in 10 people. It is one of our society's most common medical problems.

George K. Lewis, a biomedical engineering graduate student at Cornell University and his colleagues have created a miniaturized ultrasound device that would allow patients to apply ultrasound therapy to inflamed joints at home, work, or even while going about their day.

By identifying the cells that give us the ability to taste sodium, researchers have now pinpointed the taste receptor cells responsible for all 5 basic taste qualities.

Malaria, a disease that kills more than 1 million people each year, is transmitted by the bite of the Anopheles mosquito. The insects follow their victims’ scent via odor receptors found on the mosquito’s antennae and mouth parts. But the molecular basis of this process has been poorly understood.

People with a mild form of a common lung condition, even those without symptoms, are at increased risk for heart problems, according to a new study. This is the first report that mild, often-symptomless chronic obstructive pulmonary disease (COPD) may be linked to the heart's pumping ability.

Memories grow stronger when people take a break to rest, according to a new study. The finding may have important implications for how students study and how people can best learn new things.

Computational Model Can Be Used to Identify Regulatory Elements for Other Organs, Tissues Scientists have devised a new computational model that can be used to reveal genetic regulatory elements responsible for development of the human heart and maintenance of its function.

Panic disorder is an anxiety disorder that afflicts 6 million American adults. It's characterized by unexpected, repeated episodes of intense fear. These can be accompanied by physical symptoms including chest pain, heart palpitations, shortness of breath, dizziness or abdominal distress. Panic disorder is also a risk factor for suicidal behavior.

Our memory reflects our last retrieval of it rather than an exact account of the original event. When long-term memories are recalled, they become fragile and changeable. New proteins must be produced to reconsolidate retrieved memories and return them to long-term storage in the brain.

Anyone who's taken a biology class knows that a gene's sequence precisely dictates the order of amino acids that must be linked together to make a protein. A new study reveals that, in the face of an invading virus or bacteria, or an irritating chemical, the cell's protein-making machinery goes off-script, inserting more of an amino acid known to help defend proteins against damage.

US rates of new diagnoses and deaths from all cancers combined fell significantly in recent years, according to a new report. By 2020, the researchers estimate, aggressive interventions could bring colorectal cancer death rates down to as much as half their 2000 levels.

Researchers have identified a key mechanism in the brain that helps explain cocaine's addictiveness. The finding may lead to new therapeutic approaches.

Most migraine sufferers know that light can intensify headache pain. A new study of blind patients with migraine may help explain why. The finding ultimately may lead to new approaches for calming severe light-induced headaches.

After alcohol is consumed, it is first metabolized, or broken down, into acetaldehyde, a toxic chemical that causes DNA damage. About 40 percent of the East Asian population, and many people of East Asian descent throughout the world, carry a genetic mutation that produces an inactive form of Aldehyde dehydrogenase 2 (ALDH2), the main enzyme responsible for breaking down acetaldehyde into acetate, a nontoxic metabolite in the body.

Drawing on the power of DNA sequencing, researchers have identified a new group of genetic mutations involved in the deadliest form of skin cancer, melanoma. This discovery is particularly encouraging because some of the mutations, which were found in nearly one-fifth of melanoma cases, reside in a gene already targeted by a drug approved for certain types of breast cancer.

In this study, 2,600 people are being examined who suffer from Glioma which is a cancer that starts in the brain with a high mortality rate. We noticed, though these are not the final results, that there is a rise in about 60% of cases of this type of cancer among people who regularly use mobile phones. 60% in the north of Europe 100% in France, 120% in Germany. This is quite considerable.

Experimental technique safely differentiates patients with pancreatic cancer, precursor lesions and benign tumors.

A cellular protein that helps guide immune cells to the gut has been newly identified as a target of HIV when the virus begins its assault on the body's immune system, according to researchers from the National Institute of Allergy and Infectious Diseases.

Using novel light-scattering techniques, researchers have found the first evidence that early stage pancreatic cancer causes subtle changes in part of the small intestine.
