Long-COVID, viruses and 'zombie' cells: New research looks for links to chronic fatigue and brain fog

Detecting early rising Parkinson's disease (PD) symptoms could improve treatment outcomes by enabling earlier treatment interventions. In a new eNeuro paper, Daniil Berezhnoi, from Georgetown University, and colleagues used machine learning technology to detect subtle, early rising behavioral changes in mouse models of PD.

Would you dab perfume on a six-month-old? Paint their tiny nails with polish that contains formaldehyde? Dust bronzer onto their cheeks?

Today at ADLM 2025 (formerly the AACC Annual Scientific Meeting & Clinical Lab Expo), researchers will unveil a blood test developed with the help of artificial intelligence (AI) that identifies Lyme disease sooner and more accurately than the current standard—and that could translate to vastly improved patient outcomes. A second study highlights how certain generative AI tools can empower adolescents by helping them to gather useful medical information.

A new study from Karolinska Institutet shows that health care workers in Sweden have a higher risk of suicide compared to other occupational groups with similar professional levels. The study highlights the risks for physicians, registered nurses, and assistant nurses in particular.

The US Food and Drug Administration recently convened a panel of experts to examine a sensitive and increasingly urgent question: should antidepressants be prescribed to women suffering from depression during pregnancy?

Osteoblasts are specialized bone cells responsible for building and regenerating bone tissue. Researchers at Leipzig University have shown that a specific receptor plays a key role in the strength of bone cells—and how this receptor can be selectively activated. These findings could pave the way for the development of new medications with fewer side effects to help strengthen bones and muscles in aging patients. The research has been published in the journal Signal Transduction and Targeted Therapy.

Chronic liver disease (CLD) is a major global health concern, affecting approximately 1.5 billion people. This life-threatening disease often progresses silently, eventually leading to worsened conditions like liver cirrhosis or liver cancer. There is currently no treatment for CLD other than liver transplantation.

There's something oddly luxurious about sleeping in. The sun filters through the curtains, the alarm clock is blissfully silent, and your body stays at rest. Yet sleeping in is often treated as an indulgence, sometimes framed as laziness or a slippery slope to soft living.

New research by a University of Michigan psychologist and colleagues makes the strongest case yet that ultra-processed foods—including chips, cookies, soda and other heavily engineered products—aren't just tempting; they can actually be addictive.

I saw it firsthand after my cat Murphy died earlier this year. She'd been diagnosed with cancer just weeks before.

A new study has estimated, for the first time, the number of children born globally with hepatitis C virus. The research, led by researchers from the National Institute for Health Research Health Protection Research Unit in Evaluation and Behavioral Science (NIHR HPRU EBS) at the University of Bristol, estimated that each year around 74,000 children globally are born with hepatitis C virus (HCV), with around 23,000 of these children estimated to still have HCV infection at age five.

New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London, in partnership with University College London and Anna Freud, has found that negative school experiences generate twice the emotional burden in autistic and ADHD adolescents compared to their neurotypical classmates, and that this is significantly correlated with depression and anxiety.

When you're sick you'll often produce more phlegm, and might notice it's thicker or a different color: white, green, yellow or maybe even brown.

Solitary drinking has soared among young adults, climbing to rates not seen since the late 1970s.

An international study casts doubt on the widespread belief that higher levels of formal education directly protect against cognitive decline and brain aging. The study analyzed longitudinal data from more than 170,000 people in 33 western countries, making it one of the largest studies of cognitive aging to date.

You need fiber. That much is true. But in the world of online health trends, what started out as sound dietary advice has spiraled into "fibermaxxing"—a push to consume eye-watering amounts in the name of wellness.

Researchers at Edith Cowan University (ECU) have developed a cutting-edge Artificial Intelligence (AI) system that could support medical professionals in detecting and accurately diagnosing the stage of disease in a range of serious health conditions, including cardiovascular disease (CVD), diabetic eye complications, and cancer.

The targeted drug olutasidenib is highly effective in certain patients with myelodysplastic syndrome (MDS), a condition considered incurable without transplantation, according to a new clinical study led by researchers at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine.
