PTSD often overlooked in autistic people and needs better diagnosis, new analysis finds

Researchers at UCL Institute of Education, King's College London, Harvard T.H. Chan School of Public Health, and UCLA report that perceived social threats in early adolescence are associated with altered connectivity in default mode, dorsal attention, frontoparietal, and cingulo-opercular networks and with higher mental health symptom scores months later.

Every cell in the human body operates on an intricate internal schedule, governed by circadian rhythms that synchronize our biological processes with the 24-hour cycle of day and night. Coordinated by a master clock in the brain called the suprachiasmatic nucleus, these cellular clocks control essential bodily functions including sleep-wake cycles, hormone production, immune function, and metabolism. When these internal clocks are disrupted, the consequences can be profound, potentially increasing our vulnerability to diseases including cancer.

Cardiovascular-related health problems may occur in as many as 1 out of every 7 pregnancies, even among people who don't already have heart disease, according to new research published today in the journal Circulation.

In a recent study published in Cell Metabolism, a research paper provides the first evidence that sperm microRNAs act as carriers of epigenetic information, enabling the intergenerational transmission of paternal exercise capacity and metabolic health, thereby exerting profound effects on offspring development.

New artificial intelligence-generated images that appear to be one thing, but something else entirely when rotated, are helping scientists test the human mind.

Women in Australia are still being left behind when it comes to heart attack care. At the current rate, the gender gap won't close for at least another decade, according to new research from the University of Sydney.

Alzheimer's disease not only robs people of their memory but also affects mood, often causing anxiety and depression. Until now, scientists haven't fully understood how these symptoms are connected in the brain.

As new Statistics Canada data reveals that two-thirds of Canadians are considered overweight or obese, researchers are urging the public and policymakers to rethink how we define and measure health—starting with one of the most used metrics—the body mass index (BMI).

A Wayne State University study published in Nature Communications revealed that Zika virus exposure during pregnancy causes long-term, sex-specific changes to a baby's immune system, particularly affecting the frontline immune cells that fight infection.

Protected areas of defined geographic zones can slow biodiversity loss and bolster conservation efforts, but they may have unintended impacts on the diets of children who live nearby, according to new research from scientists at Penn State.

A Yale School of Medicine-led research group, working with six US health systems, reports an association between a single ambient AI scribe platform and lower short-term burnout among ambulatory clinicians.

New research from Edith Cowan University (ECU) has uncovered a surprising result in athletes following anterior cruciate ligament (ACL) reconstruction, which could impact their return to sports.

Can your brain attune itself to a foreign language before you're born? A UdeM-led team of neuropsychology researchers has found that it can. A few weeks of prenatal exposure to a new language is enough to rewire the language networks in a newborn's brain. From the very first hours of life, the foreign language heard in the womb is processed along the same neural pathways as the mother tongue, while a completely new foreign language is processed differently.

Cervical epithelial cells are far from passive bystanders in the body's immune system. New research shows they actually play an active and highly coordinated role in detecting and fighting infections. That's the conclusion of an international research team led by Associate Professor Cindrilla Chumduri from Aarhus University, published in the journal Science Advances.

The health of mothers during pregnancy has long been known to play a role in the lifelong mental and physical health of offspring. Recent studies have found that contracting an infection during pregnancy can increase the risk that offspring will develop some neurodevelopmental disorders, conditions that are associated with the atypical maturation of some parts of the brain.

Taking a page from the private insurance industry's playbook, the Trump administration will launch a program next year to find out how much money an artificial intelligence algorithm could save the federal government by denying care to Medicare patients.

From "Dr. Google" to AI-powered chatbots, the internet is full of health advice. But for a safe checkup or diagnosis, experts say it's still best to leave it to the professionals.

In September 2025, the Steven A. Cohen Military Family Clinic at the Up Center in Virginia Beach launched a campaign to raise awareness for what it calls an overlooked mental health crisis: the high rate of suicide among women veterans.
