Blood test could streamline early Alzheimer's detection in underrepresented populations

When it comes to their survival, cancer cells have a host of backup plans. This is especially true of the nutrients that cancers use to grow and spread. In addition to relying on sugars like glucose to power their proliferation, some cancer cells also use ketones—metabolites produced from fats when the body is fasting or on a low carb diet—as an alternate fuel source.

When TV personality Danielle Lloyd was diagnosed with melanoma earlier this year, she faced not only the anxiety of cancer treatment but also a disturbing reality: influencers spreading dangerous misinformation about sun protection.

A self-described science nerd is the latest American to get an experimental pig kidney transplant, at a crucial point in the quest to prove if animals organs really might save human lives.

You've probably seen the word "narcissist" thrown around online in headlines, on dating apps or in therapy-themed TikToks. But the label that people often unthinkingly slap on toxic bosses or reality TV villains hides a much more complicated psychological picture.

People with operable diffuse pleural mesothelioma may benefit from immunotherapy before and after surgery, based on results of a clinical trial exploring the sequence of treatment and the role of surgery for this difficult to treat cancer.

A new analysis comparing different dementia care approaches found that caregivers of people living with Alzheimer's disease and other dementias reported greater satisfaction with care provided through either of two comprehensive dementia care programs, compared with routine (usual) care, over an 18-month period.

Although cardiovascular disease is a leading cause of death for women, they remain underrepresented in clinical trials for common heart conditions. These findings, by investigators in the Smidt Heart Institute at Cedars-Sinai, were presented at the ESC Congress 2025 in Madrid.

Cancer immunotherapy, which primes the body's immune system to fight off tumors, has historically focused on harnessing T cells' natural ability to recognize and attack cancer cells. While this approach has saved the lives of patients with melanoma, as well as certain lung cancers and blood cancers, it has been less effective against solid tumors, which tend to be "cold" environments, where anti-cancer immune responses are inactive and cancer-killing T cells are not recruited.

As lawmakers and public health experts debate the safety of nicotine pouches, researchers from Rutgers Health found that for now, most adults that use these products also have a history of tobacco use and may be choosing these products as a possible step toward reducing or quitting more dangerous forms of nicotine delivery.

Few viruses are as widespread—and sometimes misunderstood—as the human papillomavirus, or HPV. It's so common that most of us—up to 80%—will encounter it at some point in our lives, often without even realizing it. Understanding HPV matters, given that it is linked to several types of cancer.

Post-traumatic stress disorder (PTSD) is a mental health disorder triggered by traumatic experiences such as accidents, disasters, or violence. Exposure therapy, a scientifically validated treatment for PTSD, involves the gradual re-exposure of patients to trauma-related cues to reduce anxiety and avoidance behaviors.

As a cardiologist, I frequently meet patients who have stopped taking medicines that could keep them alive. Often it's because they've seen a dramatic headline or a worrying TV report about a drug they rely on. But sometimes, patients are right to pay attention: new studies really can overturn decades of medical practice.

Robots designed for neurorehabilitation, specifically for supporting arm and leg movement and motor relearning, are increasingly being adopted for individuals with limited limb mobility due to illness or injury. However, differences in brain responses between robot-driven passive movement and active, volitional control during robot-assisted active movement are poorly understood. Elucidating these differences is crucial for understanding the mechanisms of motor learning, neuroplasticity, and functional recovery.

A dangerous new drug adulterant is spreading through America's illicit opioid supply, and it's making overdoses significantly harder to reverse. Medetomidine, a veterinary sedative normally used to sedate pets, is increasingly being mixed with heroin and fentanyl, creating a cocktail that experts warn could be far deadlier than previous street drug combinations.

Why do health stories about food and cancer grab so much attention? Because they offer an enticing promise: that a single item on your plate, or even a sudden change in what you crave, might hold the key to spotting disease early.

Contrary to widespread belief, yoga may be less effective than conventional forms of exercise in enhancing vascular health, according to a new study published in Advances in Integrative Medicine.

Infant mortality has risen in states that enacted tighter abortion restrictions in the wake of the June 2022 Dobbs v. Jackson Women's Health decision. This occurs for newborns—those less than a day old—as well as older infants—those 1 month to 1 year old.

Transcranial magnetic stimulation (TMS) was approved by the FDA to treat some patients with depression in 2008, and has since been used in treatment plans for a variety of other health issues. But the increased use of TMS raises a number of ethical considerations. For example, are health care providers doing enough to track adverse side effects? And are patients able to make informed decisions about whether to receive TMS treatment?
