Scientist seeks solutions for cancer patients with dry mouth
For several years, Wilmot Cancer Institute scientist Catherine Ovitt, Ph.D., has been investigating ways to protect and regenerate the salivary gland, which can be damaged during radiation treatment for head and neck cancer. Her lab's latest study focuses on the cells that secrete saliva—discovering the ways in which several different cell populations have the potential to restore salivary gland function.

Signs your child might have hearing loss
(HealthDay)—"Put your listening ears on!" frustrated parents often say. But some kids aren't deliberately tuning out Mom and Dad—they really can't hear them.

Taking a pill can effectively treat brutal lung disease
Researchers report in Nature Communications they figured out why air sacs in the lungs clog up with a thick substance called surfactant in a brutal disease called Pulmonary Alveolar Proteinosis (PAP), and they show taking cholesterol-busting pills called statins can effectively treat the disease.

Brains keep temporary molecular records before making a lasting memory
The first dance at my wedding lasted exactly four minutes and 52 seconds, but I'll probably remember it for decades. Neuroscientists still don't entirely understand this: How was my brain able to translate this less-than-five-minute experience into a lifelong memory? Part of the puzzle is that there's a gap between experience and memory: our experiences are fleeting, but it takes hours to form a long-term memory.

Cellular communication system in mice helps control female fertility
When Joan Jorgensen was an undergraduate at the University of Wisconsin-Madison, her roommate confided that she had just one period before going through menopause in high school. Doctors told Jorgensen's roommate that she would never have biological children.

Researchers find treatment for ultra-rare disease
A new study published in Molecular Genetics and Metabolism, conducted by a Liverpool based research collaboration involving the University of Liverpool, has identified the drug that treats the extremely rare genetic disease alkaptonuria (AKU).

First patient receives novel gene therapy for GSD
Dr. David Weinstein and his team at UConn Health have administered to a patient the world's first investigational gene therapy for potentially deadly glycogen storage disease (GSD).

Diabetes—the good news and the bad news, and what next for the future
Alarming stories about the diabetes epidemic that threatens millions of lives – and the NHS itself – have become commonplace, and with good reason. Around 4.6m people in the UK are living with diabetes while a further 12.3m are at increased risk of developing it. The NHS spends an estimated £14 billion a year on treating diabetes and its complications.

Blood biomarker can help predict disease progression in patients with COPD
Some patients with COPD demonstrate signs of accelerated aging. In a new study published in the journal CHEST researchers report that measuring blood telomeres, a marker of aging of cells, can be used to predict future risk of the disease worsening or death. Further, they have determined that the drug azithromycin may help patients with short telomeres, an indicator of more rapid biological aging, stave off negative clinical outcomes.

Gastrointestinal flora the cause of severe lung damage after blood transfusion
Knowledge that the gastrointestinal flora affects both healthy physiological processes and various disease mechanisms has increased in recent years. A study conducted at Lund University is now published in Blood Advances, and reveals a previously unknown link between the bacteria in the gut and acute lung injury after blood transfusions.

A shortcut to testing for Ebola
Viruses and poverty seem to go hand in hand, as we saw with the West African Ebola virus epidemic. But one researcher is fighting back by developing a testing kit that can tackle Ebola, even in the world's poorest places.

Diagnosis of Alzheimer's becoming more common, but less severe
Alzheimer's disease is the most common form of dementia, affecting nearly six million Americans. Aside from the incredible toll it takes on patients and their families, the estimated total cost of care is over $400 billion. As the baby boomer generation continues to age, this economic, physical, and emotional burden is only expected to increase. In the fight against Alzheimer's, it's crucial that policymakers, researchers, scientists, and physicians are armed with forecasts based on accurate assessments of this disease.

New study suggests viral connection to Alzheimer's disease
Of the major illnesses facing humanity, Alzheimer's disease (AD) remains among the most pitiless and confounding. Over a century after its discovery, no effective prevention or treatment exists for this progressive deterioration of brain tissue, memory and identity. With more people living to older ages, there is a growing need to clarify Alzheimer's disease risk factors and disease mechanisms and use this information to find new ways in which to treat and prevent this terrible disorder.

Sleep problems are influenced by our genes – but this doesn't mean they can't be fixed
Some people struggle greatly with sleeplessness, whereas others appear to be able to nod off effortlessly, regardless of the circumstances. Perhaps the most obvious explanation for differences between us in terms of our sleep is the environmental challenges that we face. An unrelenting stint at work, relationship difficulties or receiving bad news are just some of the many life challenges that can lead to sleepless nights.

Gene therapy for myotubular myopathy—early signs of success
Parents cherish developmental milestones, from a newborn's grip of an offered finger; to an infant's holding her head up the first time; to rolling over, creeping, and crawling; then to standing, cruising, and finally walking. Even kicking during a diaper change or yowling requires muscle strength and coordination. But a boy with X-linked myotubular myopathy (MTM) is so weak that even breathing is a huge struggle. If a baby survives the initial hospital stay, care at home becomes a full-time job and is only supportive, delaying the inevitable. That grim picture may be changing.

Researchers address sleep problems in Parkinson's disease
A team of researchers at VIB and KU Leuven has uncovered why people with a hereditary form of Parkinson's disease suffer from sleep disturbances. The molecular mechanisms uncovered in fruit flies and human stem cells also point to candidate targets for the development of new treatments.

Identifying a subgroup of heart failure patients could lead to improved care
For more than six decades, oxidative stress has been linked to heart failure, a progressive weakening of the heart muscle that can lead to death. While antioxidant supplements such as vitamin C, vitamin B and beta-carotene have been widely used in heart failure, they often prove ineffective.

Fake organs guide the way for 'impossible' cancer surgery
Anthony Camnetar remembers the first time he was told that he had von Hippel-Lindau syndrome, a rare genetic disorder. He was 12 years old and his mother, who had just picked him up from school, broke the news through tears realizing the health challenges her son would face for the rest of his life.

Immigration agents X-raying migrants to determine age isn't just illegal, it's a misuse of science
A teenager's father is murdered in Somalia, and the boy travels to the United States seeking asylum. Another teen's father and brother are murdered by extremist groups in Afghanistan and he too makes his way to the U.S. to seek asylum. Since both are minors, federal law decrees that they must be held separately from adults under the oversight of the Office of Refugee Resettlement (ORR).
