A study has found that placing older adults in a simulated high-altitude environment for a week before major surgery greatly improved their hemoglobin levels, addressing a common preoperative problem, anemia, that can lead to surgical complications.

Researchers investigating the genetics underlying the airway inflammation seen in severe asthma have, for the first time, discovered that proteins that bind to RNA are dysregulated, driving changes in gene expression in cells that line the airways.

Around 1.6 million Americans live with inflammatory bowel disease, dealing with persistent and debilitating relapses. Scientists have identified how a specialized subset of T cells falter in flare-ups, and they may hold they key to long-term recovery.

One of the most common treatments for sleep apnea involves wearing an air mask while sleeping, which can be awkward and uncomfortable. A new study, however, suggests that a simple TENS muscle-stimulating system may actually work better.

While weight-loss surgery is effective, it can also be expensive and come with a host of unpleasant side effects. Scientists hope that by regulating a certain bile acid, the benefits of surgery can be replicated without a single invasive procedure.

Two new studies have highlighted the potential impact of SARS-CoV-2 infections during pregnancy, finding placental abnormalities and fetal haemorrhages. Researchers are now investigating whether there are long-lasting neurodevelopmental effects.

The results of a fascinating clinical trial challenge popular assumptions regarding "safer" strains of cannabis. The research found higher levels of cannabidiol (CBD) do not negate any potential adverse effects from smoking cannabis.

A new study has demonstrated that an app designed to turn a smartphone into an electronic stethoscope can capture reliable, quality recordings of user heartbeats across the population, which could be used to remotely monitor heart conditions.

Scientists have identified the earliest known mammal – a small shrew-like animal that lived 225 million years ago. The species, Brasilodon, had previously been categorized differently, but new research reveals a distinctly mammalian tooth structure.

There is good and bad news in a study tracking half a million subjects after COVID-19. The study found patients were at greater risk of heart problems and new diabetes diagnoses for weeks after an infection but that risk did return to normal over time.

A newly published meta-analysis has uncovered 10 new genetic variants that contribute to age-related hearing loss. The findings indicate a part of the ear known as the stria vascularis may play a part in hearing impairment.

Hundreds of scientists around the globe have shared data to create the world's first brain growth chart. The project incorporated MRI scans from subjects of all ages to offer a unique portrait of how our brains change over the course of a lifetime.
