Currently, doctors who need to continuously monitor a patient’s blood pressure must surgically insert a catheter into one of the individual’s arteries. However, a safer and much less invasive alternative might be on the horizon, inspired by the tuning of guitar strings.

A new injectable, temporary pacemaker could address heart arrhythmias in emergencies. This nanoparticle gel can regulate the heart’s electrical signals for up to five days before safely dissolving in the body. Arrhythmias occur when the heart’s rhythm becomes too fast, slow, or irregular, leading to serious complications if untreated. While defibrillators and surgically implanted pacemakers

For babies with a heart defect, implanting a ‘shunt‘ is vital. A new light-expanding shunt could reduce the need for multiple heart surgeries as the baby grows. Understanding Hypoplastic Left Heart Syndrome Hypoplastic left heart syndrome occurs when the left side of the heart remains severely underdeveloped and thus cannot support blood circulation throughout the

Scientists have made a significant discovery that could pave the way for new treatment options for celiac patients. The team pinpointed where the gluten response starts and found that certain cells play a bigger role than previously believed. Understanding the Immune Response in Celiac Disease Similar to other autoimmune diseases, celiac disease occurs when the

A 60-year-old man in Germany has become at least the seventh person with HIV to be declared free of the virus after receiving a stem-cell transplant. Although he has been virus-free for almost six years, he is only the second person to receive stem cells that are not naturally resistant to the virus. Expert Reactions

Modern prosthetic limbs help people with amputations walk naturally but don’t give full neural control. They use robotic sensors and pre-set algorithms to move. MIT researchers, with Brigham and Women’s Hospital, developed a new surgical method and neuroprosthetic interface. This allows a prosthetic leg to be controlled entirely by the nervous system. By reconnecting muscles

Early medical intervention is crucial for stroke victims, and a new smartphone tool aims to facilitate this by enabling first responders to quickly assess whether a patient has suffered a stroke. Improving Stroke Treatment with Early Detection Tools In such instances, patients undergo a series of assessments upon arrival at the hospital. If these tests

DNA is a much denser data storage medium than anything humans can design, but it is fragile. Scientists have now mimicked nature by creating artificial amber to protect DNA for long-term data storage.
A single gram of DNA can hold up to 215 petabytes (215 million GB) of data, making it possible to store the entire internet in a shoebox. Thus, scientists have been experimenting with writing, reading, and protecting data stored in DNA.

“Don’t think about the start of the race, think about the ending.” Usain Bolt. Running for more than 120 kilometers (75 miles) every week for 10 hours may seem like really intense exercise. However, instead of harming their bodies, a recent study indicates that some professional athletes who do this kind of tough workout are

Total knee replacement surgery is a very common procedure where a damaged knee joint is replaced with an artificial one. In the U.S., about 790,000 of these surgeries happen each year, and this number is expected to go up because of aging populations, more obesity, and more young people needing knee replacements. The main reason
