How the aging gastrointestinal tract drives age-related cognitive decline

We become forgetful as we age. This is often seen as a universal truth, but in fact it is far from universal: some people remain incredibly sharp at 100 years old, while others experience memory loss starting in middle age.

Electrical stimulation restores movement and sensory feedback after severe spinal injury

The effects of spinal cord injuries are complex and multifaceted. People lose not only the ability to control the movement of their limbs, but also the ability to receive sensory feedback from them. Both are critical to generate the coordinated movement involved in walking.

New optovolution technique uses light to guide protein evolution

Evolution is biology's powerful method of engineering. It works by generating many variants of DNA, RNA, and proteins inside cells and letting nature "select" the organism that performs best.

New study shows the brain reactivates memories without reaching conscious thought

Researchers have used brain imaging to show how memories can be reactivated in the brain without them reaching conscious awareness, showing that these memories persist even when we think they have been forgotten.

New microscope captures 3D blood flow and oxygenation at single-cell resolution

The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural tissue like electrical wires.

A hidden movement map discovered in the brain’s insula

Mayo Clinic researchers have identified a hidden "movement map" deep within the brain - a discovery that could help surgeons reduce side effects from epilepsy procedures and guide future treatments for speech and movement disorders.

Corneal nerve function declines with age in aniridia patients

Congenital aniridia is a rare disease caused, in most cases, by mutations in the PAX6 gene, which is essential for the development of ocular structures.

Five sessions a day TMS approach may reduce depression symptoms in one week

For the many patients with depression who haven't found relief through medication, transcranial magnetic stimulation (TMS) - a noninvasive therapy that uses magnetic pulses to stimulate specific areas of the brain - has become an increasingly important treatment option.

Certain brain regions found to be more active in people with obsessive-compulsive disorder

A new study revealed that certain brain regions are more active in people with obsessive-compulsive disorder (OCD) during cognitively demanding tasks.

Cyborg transplants may advance cell-based therapies for diabetes

A new electronic implant system can help lab‑grown pancreatic cells mature and function properly, potentially providing a basis for novel, cell-based therapies for diabetes.

Key protein regulates slow oxytocin release in the brain

The brain does not only communicate through fast electrical impulses; it also relies on slower, more diffuse chemical signals that modulate our emotional and social states over time.

Sleep loss triggers brain fluid pulses that impair attention, study finds

Sleep deprivation causes attentional lapses that coincide with coordinated changes in brain activity, pupil diameter, blood flow, and cerebrospinal fluid dynamics. These findings suggest attention failures reflect a transient brain–body state linked to sleep pressure rather than isolated neural errors.

Brain network discovery opens new path for Parkinson’s treatment

Parkinson's disease, a progressive neurological disorder affecting more than 1 million people in the U.S. and more than 10 million globally, is characterized by debilitating symptoms such as tremors, movement difficulties, sleep disturbances and cognitive impairments.

Electromagnetic therapy that stimulates the brain reduces overall disability in stroke survivors

A type of therapy that stimulates specific brain pathways with electromagnetic pulses combined with physical therapy significantly reduced overall disability in stroke survivors compared to survivors who received sham (inactive) electromagnetic stimulation combined with physical therapy, according to a preliminary study to be presented at the American Stroke Association's International Stroke Conference 2026.

Transcranial magnetic stimulation can be a cost-effective treatment option for depression

A major new study has found that transcranial magnetic stimulation (TMS), which applies magnetic energy to the brain, can be a cost-effective treatment option for the NHS in treating moderate and severe forms of depression that have not responded to other treatments.

See through the skin: New technology spots early heart disease warning signs

Researchers from Helmholtz Munich and the Technical University of Munich (TUM) have developed "fast-RSOM", a new imaging technology that can capture detailed images of the smallest blood vessels directly through the skin – without the need for invasive procedures.

Gambling disorder alters the brain's control and reward systems

A new doctoral dissertation shows that gambling disorder is linked to brain networks involved in self-control and brain reward functions.

Rhythmic carbon dioxide exposure may enhance brain waste clearance mechanisms

Abnormal clumps of proteins like α-synuclein, amyloid beta and tau are associated with neurodegenerative conditions like Parkinson's and Alzheimer's disease, but a waste removal mechanism called the glymphatic pathway can clear these proteins and other metabolic byproducts from the brain.

Implanted vagus nerve stimulation device offers lasting relief for severe depression

About 20% of U.S. adults experience major depression in their lifetime. For most people, symptoms improve within a few treatment attempts, but up to one-third of patients have treatment-resistant depression, for which standard antidepressant medication or psychotherapy isn't enough.
