Napping for more than an hour a day could be an early sign of Alzheimer’s disease according to new research. It’s suggested excessive daytime napping shares a bidirectional relationship with dementia, reflecting and shaping changes in the brain.

Do you thrive on between four and six hours of sleep per night? You may be an “elite sleeper,” and a new study reports the same genes associated with short sleep patterns may also slow the onset of brain diseases such as Alzheimer’s.

A new study has built on evidence indicating long COVID symptoms may be linked to immune system activity. The research found markers of inflammation in the cerebrospinal fluid of patients experiencing brain fog months following a mild case of COVID-19.

A post-mortem brain tissue study is offering clues as to how exercise in old age can prevent cognitive decline. The research found late-life physical activity was linked to high levels of presynaptic proteins, known to support healthy brain functions.

Scientists have successfully used CRISPR and phages to edit the genome of bacteria in the gut microbiome of live mice for the first time. The breakthrough could help manipulate the ratio between different species to treat a range of health problems.

An incredible proof-of-concept study has demonstrated how a brain implant can treat severe depression using electrical stimulation. The implant tracks neural activity for patterns of depression and zaps a key region in real-time to disrupt the cycle.

Patients with kidney failure require regular dialysis, an invasive and potentially risky treatment. But now researchers have successfully demonstrated a prototype bioartificial kidney, which can be implanted and works without the need for drugs.

Researchers have demonstrated, for the first time, a brain implant turning neural activity into full words. The first participant in the trial, a paralyzed man, can now speak with a vocabulary of 50 words by simply thinking about vocalizing words.

A landmark study is describing the successful results of a trial testing a targeted gene therapy for children with a rare genetic disease. The research demonstrates a novel method for delivering gene therapies to specific locations deep in the brain.

A new study investigating how a low-calorie diet alters gut microbial populations is reporting unexpected results, finding a strange relationship between extreme caloric restriction and increased levels of a bacteria linked to inflammatory bowel disease.

Aging comes for us all – but perhaps the unpleasant symptoms don’t have to. In a new study, scientists have found a kind of anti-aging immunotherapy, reinvigorating immune cells to better clear out defunct cells that contribute to the aging process.

A study is demonstrating a new screening method developed to better identify human-made chemicals in people. The proof-of-concept research discovered more than 100 chemicals, including 55 that have never been reported found in humans before.
