Introduction: New research from the UK Dementia Research Institute has revealed that smartwatches can potentially detect Parkinson’s disease even before the onset of typical symptoms, enabling a clinical diagnosis up to seven years in advance. By analyzing data collected from smartwatches, researchers utilized artificial intelligence (AI) to accurately predict individuals who would later develop Parkinson’s disease. This breakthrough has the potential to serve as a novel screening tool, allowing for early detection and intervention in comparison to current diagnostic methods.

The Study: The study involved analyzing data from a large cohort of 103,712 participants in the UK Biobank. These individuals wore medical-grade smartwatches for seven days between 2013 and 2016, with the watches recording and measuring average acceleration as an indicator of movement speed. Two groups were compared: participants who had already been diagnosed with Parkinson’s disease and individuals who received a diagnosis up to seven years after the smartwatch data was collected. These groups were then compared to a control group of healthy individuals matched in age and sex.

A groundbreaking study published in PNAS reveals that an RNA nanoparticle therapy has the potential to prevent the spread of multiple myeloma (MM), a type of bone marrow cancer, in mice. Administered alone or in combination with an FDA-approved MM drug, the therapy demonstrated reduced tumor burden and increased survival rates in the mouse model. This research, conducted by scientists at the University of Pennsylvania School of Engineering and Applied Science, presents a promising avenue for treating this incurable disease.

Understanding Multiple Myeloma: Multiple myeloma affects plasma cells, a type of white blood cell found in the bone marrow. These cells produce antibodies that aid in fighting infections. However, MM leads to the production of abnormal proteins that negatively impact various bodily functions, including kidney health and blood cell production. The aggressive nature and rapid mutation rate of MM make it challenging to treat effectively. In 2020 alone, MM was responsible for over 100,000 deaths worldwide, and patients with advanced and chemotherapy-resistant MM typically have a survival rate of just six to nine months. Innovative therapies are urgently needed to improve patient outcomes.

Researchers at Harvard’s Wass Institute and John A. Paulson School of Engineering and Applied Sciences (SEAS) have made significant progress in developing a synthetic heart valve with potential applications for growing children. Known as FibraValve, this implant can be created in a matter of minutes using a spun-fiber technique that enables the shaping of the valve’s delicate flaps at a microscopic level. The valve is designed to be colonized by the patient’s own living cells, allowing it to develop and grow as the child matures.

FibraValve builds upon the team’s previous creation, JetValve, an artificial heart valve introduced in 2017 that shared similar principles. The updated version incorporates “focused rotary jet spinning,” which utilizes streams of focused air to more rapidly and precisely collect synthetic fibers on a spinning mandrel. This enhancement facilitates finer adjustments to the valve’s shape, enabling the polymer’s micro- and nano-fibers to more accurately mimic the tissue structure of a natural heart valve. The entire manufacturing process can be completed in less than 10 minutes, in contrast to alternative methods that may take hours.

Sunburns are terrible. The skin blisters and peels. Even a light brush from putting on clothes or tucking into bed sheets is agony.

Now imagine having those blisters at just six months old. But the sun isn’t the culprit; your genes are.

Thousands of people in the US suffer from dystrophic epidermolysis bullosa (DEB), a rare genetic disorder that severely affects the structure and integrity of the skin and eyes. Children with this illness have skin as delicate as wet tissue paper. Chronic painful blisters and wounds, sometimes even in their throats, are an everyday part of their lives from birth.

The underlying cause of DEB is a single gene mutation that impacts a critical protein responsible for maintaining skin integrity. This genetic error makes the illness an ideal candidate for gene therapy. However, due to the fragility of the skin, traditional gene therapy methods involving injections are difficult to tolerate.

But what if a genetic moisturizer could be the solution?
