Giving birth to a child after 40 is becoming more and more common – but it can entail an increased risk to the child.

A single pellet of recycled plastic can contain over 80 different chemicals. A new study with researchers from University of Gothenburg and Leipzig shows that recycled polyethylene plastic can leach chemicals into water causing impacts in the hormone systems and lipid metabolism of zebrafish larvae.

Insulin resistance detected by routine triglyceride-glucose (TyG) index can flag people with early Alzheimer's who are four times more likely to present rapid cognitive decline, according to new research presented at the European Academy of Neurology (EAN) Congress 2025.

Colistin is a potent, last-resort antibiotic, used only to treat people with dangerous, life-threatening bacterial infections that have developed resistance to other drugs.

Scientists identified 473 human genes that act as genetic “on/off switches,” shaping disease risk through tissue-specific or universal patterns regulated by DNA changes and hormones. These findings could pave the way for more precise diagnostics and personalized therapies across cancers, immune, skin, and metabolic diseases.

Men lose more weight than women on a ketogenic diet, according to a comprehensive review in Frontiers in Nutrition. Sex differences in hormones, metabolism, and fat distribution influence the effectiveness of the ketogenic diet for obesity.

Researchers used deep metagenomic sequencing to trace zoonotic pathogens and antibiotic resistance genes from cow manure into the guts of muscid flies on a French dairy farm. Findings reveal that flies not only carry but may amplify dangerous microbes, underscoring public health risks.

Researchers from Tokyo Metropolitan University have created a new way of telling "aged" human cells apart from younger ones using electric fields.

About 570 people in England and Wales are expected to die as a result of high temperatures from Thursday 19 June 2025 to Sunday 22 June 2025, a rapid study has estimated.

New research suggests that a healthy microbiome before chemotherapy could help protect breast cancer patients against heart damage, or cardiotoxicity, as a result of cancer therapy.

Liver fibrosis, a pathological condition in which the liver becomes stiff and scarred,
commonly develops in the progression of chronic liver diseases such as chronic hepatitis
and metabolic dysfunction-associated steatohepatitis (MASH).

New research, presented today at the European Academy of Neurology (EAN) Congress 2025, has uncovered a powerful link between nighttime heart rhythm and future health conditions, even in people with no obvious sleep problems.

A team of international researchers led by scientists at City of Hope®, one of the largest and most advanced cancer research and treatment organizations in the United States, with its National Medical Center named a Top 5 "Best Hospital" in the nation for cancer care by U.S. News & World Report, provide the most thorough account yet of an elusive target for cancer treatment.

It's difficult to overstate the corrosive impact of Canada's ongoing opioid crisis. Since 2016, there have been over 40,000 opioid-related deaths across the country, devastating Canadian families from all walks of life. Opioid-related hospitalizations and calls to paramedics have ballooned.

A new study reveals that when we experience short-term (acute) pain, the brain has a built-in way to dial down pain signals - like pressing the brakes - to keep them from going into overdrive.

Scientists at St. Jude Children's Research Hospital and Dana-Farber Cancer Institute today report the identification of a novel combination therapy approach to treat pediatric acute myeloid leukemia (AML).

A new laboratory method developed by researchers at Columbia University Vagelos College of Physicians and Surgeons may now help physicians more quickly diagnose patients with suspected genetic disorders of the immune system, many who have been trapped in diagnostic limbo for years.

The Simons Foundation Autism Research Initiative (SFARI) has released phenotypic and genetic data from the Autism Inpatient Collection (AIC), a cohort of more than 1,500 youth participants ages 4 to 20 years old who were hospitalized in one of six child psychiatry units in the United States.

Scientists from Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago and colleagues identified several proteins from the umbilical cord blood of preterm newborns that signal acute systemic inflammation as an immune response to infection, providing objective and noninvasive means to diagnose early onset sepsis.

Good sleep is vital for adolescents' physical health, mental well-being, and academic success - yet many don't get enough rest. Now, a new study reveals bedtime screen habits may be to blame.
