Scientists discovered that fasting may help reverse heart damage caused by a specific genetic mutation in the PLN gene called R14del. This mutation causes a common type of inherited heart disease where abnormal protein clumps build up in heart cells. The research shows that fasting activates the cell's cleanup system (lysosomes) to remove these harmful clumps and restore heart function.
WHY IT MATTERSIf confirmed in human studies, fasting could offer PLN R14del cardiomyopathy patients a non-drug intervention to potentially reverse heart damage, though this is currently only demonstrated in laboratory research and requires clinical validation.

Scientists are studying a new type of medicine made from circular RNA, which is RNA shaped like a circle instead of a line. Because of their circular shape, these medicines may stay in the body longer and work better than current RNA medicines. Researchers are testing these circular RNA medicines to treat cancer, immune system diseases, and rare diseases.
WHY IT MATTERSCircular RNA therapeutics could eventually offer longer-lasting treatments for rare diseases with fewer doses needed, but patients should know that claims about safety and effectiveness vary depending on how the medicine is made—there's no one-size-fits-all answer yet.

Researchers found that data from smartphones and wearable devices, collected over several years through a health app, can help doctors identify people with a rare lung disease called idiopathic pulmonary arterial hypertension (IPAH) earlier than before. The study used information like heart rate and activity levels from the My Heart Counts app to spot differences between people with IPAH and healthy people. This discovery could lead to faster diagnosis of this serious condition.
WHY IT MATTERSEarlier detection of IPAH could allow patients to start treatment sooner, potentially slowing disease progression and improving outcomes for this condition that currently has no cure.

A new study from Denmark found that people with higher levels of HCB (a pesticide that was banned in many countries) in their blood may have a higher risk of developing ALS, a disease that affects nerve cells and causes muscle weakness. HCB was used as a pesticide in the past but is no longer allowed in many places because it can be harmful to health. This research suggests that exposure to this old pollutant might be connected to ALS risk.
WHY IT MATTERSIf you have ALS or a family history of it, understanding environmental risk factors like HCB exposure could help you and your doctor identify potential causes and discuss ways to reduce exposure to similar pollutants.

Researchers developed an artificial intelligence tool that can accurately detect bleeding inside joints in adults with hemophilia by analyzing ultrasound images. This technology could eventually allow patients to get ultrasound scans at home instead of traveling to a hospital or clinic. Early detection of joint bleeding is important because it helps prevent long-term damage to the joints.
WHY IT MATTERSHemophilia patients currently must travel to medical facilities for ultrasound imaging to detect joint bleeds; this AI tool could enable home-based monitoring, reducing travel burden and potentially catching bleeding episodes earlier.

Scientists found that haloperidol, a medication normally used to treat psychiatric conditions, may help treat spinal muscular atrophy (SMA) by increasing levels of a protein called SMN that is missing or low in SMA patients. In laboratory tests with mouse cells and human patient cells, haloperidol helped nerve cells survive longer, reduced harmful inflammation, and improved movement. This suggests haloperidol could potentially be used alongside or instead of current SMA treatments.
WHY IT MATTERSIf haloperidol proves effective in human trials, SMA patients could potentially benefit from a medication that already exists and is FDA-approved, potentially offering a faster path to treatment than developing entirely new drugs.

Researchers in New Zealand interviewed 15 people with rare diseases and their caregivers to understand what it's like to get diagnosed and treated. They found that patients often have to fight hard to get answers and support because doctors don't know much about rare diseases. The study shows that people with rare diseases face similar challenges, even though their specific conditions are very different.
WHY IT MATTERSThis research directly documents the real-world barriers that rare disease patients face in accessing diagnosis and care in New Zealand, providing evidence that could help healthcare systems improve support for the estimated 300 million people worldwide living with rare disorders.

Researchers studied blood proteins in over 2,400 older adults to find which ones might predict memory and thinking problems later in life. They found 34 proteins linked to faster decline in orientation (knowing where you are and what time it is) and 18 proteins linked to memory loss over 15 years. This early-stage research could help doctors identify people at risk for dementia before symptoms appear.
WHY IT MATTERSIf validated, these protein signatures could enable blood tests to identify people at risk for cognitive decline years before symptoms develop, potentially opening windows for preventive treatments in Alzheimer's disease and related dementias.
