    Vaccine Shows Promise for Preventing Active TB Disease

    An experimental vaccine proved 50% effective at preventing latent tuberculosis infection from turning into active disease in a three-year study of adults in Africa. Doctors were encouraged because protection declined only a little after two years, and even a partially effective vaccine would be a big help against TB. The lung disease kills more than a million people a year,...

    New Clues on Why Women's Alzheimer's Risk Differs From Men's

    New research gives some biological clues to why women may be more likely than men to develop Alzheimer’s disease and how this most common form of dementia varies by sex. At the Alzheimer’s Association International Conference in Los Angeles on Tuesday, scientists offered evidence that the disease may spread differently in the brains of women than in men. Other researchers...

    A Healthy Lifestyle May Offset Genetic Risk for Alzheimer's

    A healthy lifestyle can cut your risk of developing Alzheimer’s or other forms of dementia even if you have genes that raise your risk for these mind-destroying diseases, a large study has found.

    Companies Report Progress on Blood Tests to Detect Cancer

    A California company says its experimental blood test was able to detect many types of cancer at an early stage and gave very few false alarms in a study that included people with and without the disease. Grail Inc. gave results in a news release on Friday and will report them Saturday at the American Society of Clinical Oncology meeting...

    US Pregnancy Deaths Are Up, Especially Among Minorities

    Pregnancy-related deaths are rising in the United States and the main risk factor is being black, according to new reports that highlight racial disparities in care during and after childbirth. Black women, along with Native Americans and Alaska natives, are three times more likely to die before, during or after having a baby, and more than half of these deaths...

    Alzheimer's Association Finds Few Seniors Are Getting Routine Memory Checkups

    Few seniors get their thinking and memory abilities regularly tested during check-ups, according to a new report from the Alzheimer’s Association that raises questions about how best to find out if a problem is brewing. Medicare pays for an annual “wellness visit” that is supposed to include what’s called a cognitive assessment — a brief check for some early warning...

    Scientist Claiming Gene-Edited Babies Reports 2nd Pregnancy

    Leading scientists see even more reasons to worry and have more questions than answers after a Chinese scientist attended an international conference Wednesday and repeated his claim to have helped make the world’s first gene-edited babies. He Jiankui spoke at the gene-editing meeting in Hong Kong where the conference’s leader called his experiment “irresponsible” and evidence that the scientific community...

    New Exercise Guidelines: Move More, Sit Less, Start Younger

    Move more, sit less and get kids active as young as age 3, say new federal guidelines that stress that any amount and any type of exercise helps health. The advice is the first update since the government’s physical activity guidelines came out a decade ago. Since then, the list of benefits of exercise has grown, and there’s more evidence...

    Studies in Healthy Older People Aim to Prevent Alzheimer's

    It may be too late to stop Alzheimer’s in people who already have some mental decline. But what if a treatment could target the very earliest brain changes while memory and thinking skills are still intact, in hope of preventing the disease? Two big studies are going all out to try. Clinics throughout the United States and some other countries...

    AIDS Drugs Show More Promise for Preventing New Infections

    New research shows more promise for using AIDS treatment drugs as a prevention tool, to help keep uninfected people from catching HIV during sex with a partner who has the virus. There were no infections among gay men who used a two-drug combo pill either daily or just before and after sex with someone with HIV, one study found. In...

    Drug-Resistant ‘Nightmare Bacteria' Pose Growing Threat: CDC

    “Nightmare bacteria” with unusual resistance to antibiotics of last resort were found more than 200 times in the United States last year in a first-of-a-kind hunt to see how much of a threat these rare cases are becoming, health officials said Tuesday. That’s more than they had expected to find, and the true number is probably higher because the effort...

    Doctors Try Glowing Dyes to Find Hidden Cancers

    It was an ordinary surgery to remove a tumor — until doctors turned off the lights and the patient’s chest started to glow. A spot over his heart shined purplish pink. Another shimmered in a lung. They were hidden cancers revealed by fluorescent dye, an advance that soon may transform how hundreds of thousands of operations are done each year....

    Blood Test to Detect 8 Cancers Early Gives Promising Results

    Scientists are reporting progress on a blood test to detect many types of cancer at an early stage, including some of the most deadly ones that lack screening tools now. Many groups are working on liquid biopsy tests, which look for DNA and other things that tumors shed into blood, to try to find cancer before it spreads, when chances...

    In a Milestone Year, Gene Therapy Finds a Place in Medicine

    After decades of hope and high promise, this was the year scientists really showed they could doctor DNA to successfully treat diseases. Gene therapies to treat cancer and even pull off the biblical-sounding feat of helping the blind to see were approved by U.S. regulators, establishing gene manipulation as a new mode of medicine. Almost 20 years ago, a teen’s...

    Blood Test May Help Predict Which Breast Cancers Will Recur

    A blood test five years after breast cancer treatment helped identify some women who were more likely to relapse, long before a lump or other signs appeared, a preliminary study found. It was the largest experiment so far to use these tests, called liquid biopsies, for breast cancer. Results suggest they someday may help reveal which women need longer preventive...

    ‘Invisible Mending': US Scientists Try 1st Gene Editing in the Body

    Scientists for the first time have tried editing a gene inside the body in a bold attempt to permanently change a person’s DNA to try to cure a disease. The experiment was done Monday in California on 44-year-old Brian Madeux. Through an IV, he received billions of copies of a corrective gene and a genetic tool to cut his DNA...

    Half of US Adults Have High Blood Pressure in New Guidelines

    New guidelines lower the threshold for high blood pressure, adding 30 million Americans to those who have the condition, which now plagues nearly half of U.S. adults. High pressure, which for decades has been a top reading of at least 140 or a bottom one of 90, drops to 130 over 80 in advice announced Monday by a dozen medical...
