U.S. medical organizations are looking to reduce deaths caused by heart disease, the nation's No. 1 killer, with new guidelines that reframe prevention as a lifelong battle that begins with testing in childhood.

In 1991, the U.S. experienced a significant shift in cancer death rates, as, for the first time, deaths began a steady decline that continues to the present day. Researchers at Mississippi State's Social Science Research Center, in partnership with scientists at Oak Ridge National Laboratory, examined this decline to identify where and who benefited the most from this dramatic improvement.

An experimental drug designed to silence a gene strongly linked to Parkinson's disease has shown encouraging effects in a first-in-human clinical trial, according to a study published in Nature Medicine. The drug, known as BIIB094, targets LRRK2, the most common genetic contributor to Parkinson's disease; variants in LRRK2 are known to increase the risk of developing the neurodegenerative disorder, which affects nearly 10 million people worldwide.

A randomized trial conducted by the Alliance for Clinical Trials in Oncology has found that duloxetine, a medication commonly used to treat chronic pain and psychiatric conditions, does not prevent nerve damage caused by chemotherapy in patients with colorectal cancer. The primary analysis of Alliance A221805 was published in JCO Oncology Advances

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive memory loss and a decline in mental functions. These symptoms are known to arise from an abnormal buildup of proteins known as amyloid and tau, which can damage or gradually destroy neurons and the connections between them.

Your morning cup of coffee may be more than just a pick-me-up. It may also be a simple boost for your mental well-being. In a recent study, researchers from Fudan University, China, wanted to find out whether the amount of coffee a person drinks each day and the type they choose have any bearing on their risk of developing stress and mood disorders over time.

In a systematic review and meta-analysis, researchers found that occupational exposure to talc that is not contaminated with asbestos is not associated with an increase in the risk of lung cancer, mesothelioma, or laryngeal cancer. The findings are published in the Journal of Thoracic Oncology.

More than 35,000 men in the United States die from prostate cancer each year. Now, a new study reveals the immune cell weaponry we might use to save lives.

Injectable peptides are the new anti-aging trend sweeping the beauty industry. These compounds are promoted on social media as tools for skin repair, collagen production and "cellular rejuvenation." They are widely available online from overseas sellers, despite many peptides being unregulated in Australia.

Allergy affects more than one billion people worldwide—and the number is rising. For many, it means mild symptoms such as itching and a runny nose. For others, it can develop into life-threatening reactions. Now, two new studies bring researchers an important step closer to both understanding and potentially controlling the mechanisms that drive allergic disease. An international research team has mapped how the body's central allergy antibody, IgE, functions at the molecular level—and at the same time demonstrated a new way to block allergic reactions.
