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.

As hospitals adapt to various viral challenges, a new kind of viral phenomenon is gaining attention: generative artificial intelligence (AI) in the workplace. Prominent healthcare institutions, like Boston Children’s Hospital, are at the forefront of embracing technological advancements to revolutionize productivity in the healthcare industry.

With healthcare accounting for approximately 18 percent of the U.S. GDP, it is natural for organizations to seek the latest technologies to enhance their operations. Boston Children’s Hospital, known for its consistent ranking among the top children’s hospitals in the United States, has a dedicated “Chief Innovation Officer” named John Brownstein. Brownstein, an epidemiologist, oversees the Innovation & Digital Health Accelerator division, which combines technology and health to drive innovation.

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?

Artificial intelligence (AI) is playing an increasingly significant role in the realm of health and wellness, aiding in tasks ranging from cancer detection to medical documentation. Now, AI has the potential to simplify the process of providing patients with a more natural and functional smile, particularly in dentistry.

According to a press release from the University of Hong Kong, researchers at the university have recently developed an AI algorithm that employs 3D machine learning to design personalized dental crowns with a higher level of accuracy compared to traditional methods. The AI algorithm analyzes data from the adjacent teeth to ensure a more precise and natural fit, surpassing the crowns created using conventional techniques.

The study, published in the journal Dental Materials, highlights the significance of dental crowns. These tooth-shaped caps are placed over existing teeth or implants to enhance the appearance and function of damaged, misshapen, weakened, or discolored teeth, or to replace missing teeth when used with an artificial implant, as explained by the American Dental Association (ADA).

In a groundbreaking study, researchers have discovered a remarkable method to artificially induce hibernation using ultrasonic pulse technology. This innovative breakthrough holds the potential to enable future astronauts to hibernate during extended space missions. The study, conducted at Washington University in St. Louis, successfully induced a state of torpor in rats, which do not naturally hibernate.

Torpor is a sleep-like state observed in certain mammals and birds, characterized by significantly reduced body temperature and metabolism. It allows organisms to conserve energy and endure harsh environmental conditions, such as extreme cold or limited food availability.

When individuals lose a limb, they often experience a curious phenomenon known as a phantom limb, where they perceive sensations in the region of the missing appendage as if it were still present. Despite extensive research, scientists have yet to fully comprehend the underlying causes of this intriguing phenomenon. In a groundbreaking development, a recent paper published in the journal Science reveals that individuals with phantom limb sensations can also experience changes in temperature. This newfound understanding may pave the way for the creation of advanced prosthetics that incorporate thermal sensation, providing amputees with a more immersive and natural experience.

Detecting Temperature in Phantom Limbs:

A team of researchers from Italy and Switzerland has discovered that amputees can perceive temperature changes in their phantom limbs. For instance, if heat is applied to the residual limb, some individuals may be able to discern the sensation and even articulate phrases like, “You’re warming up my left index finger.” While scientists were aware of amputees experiencing tactile sensations and pain in their phantom limbs, this is the first documented evidence of temperature detection.
