In May 2023, 140 doctors, nurses, and support staff performed the world’s first successful whole-eye transplant. The 21 hour surgery took place in an operating room at New York University Langone, one of the United State’s leading hospitals. The full-eye transplant was complemented with a partial face transplant that included a new nose, lips, and cheeks.

Reproduction is one of the most important mechanisms for survival for all species, and humans are no exception. Infertility, defined as the inability to achieve pregnancy after a year of trying, currently affects 1 in 6 couples globally. Causes could be anything from genetics to lifestyle choices to pollutant exposures. Recently, scientists have created lab-engineered embryos that may be the key to better understanding human development.

One in eighteen people in the United States have an arrhythmia (an irregular heartbeat). For adults over forty, one in four could develop an arrhythmia. An irregular heartbeat could last for a brief amount of time and be harmless to a person's health. On the flip side, arrhythmias that persist for a long period of time can increase stroke risk and lead to premature death. Possible treatment options include open heart surgery but more commonly default to pacemaker placement. In fact, almost three million Americans live with pacemakers. However, a new treatment option designed by Northwestern University and the University of Texas at Austin offers a sophisticated alternative to pacemakers.

In the United States, more than 131 million people, or 66% of all adults in the United States, use prescription drugs to help heal chronic conditions. Billions of dollars are spent on prescribed drugs, yet we must ask ourselves how effective medication is for any given disease. Researchers at the University of Notre Dame hope to help answer this question. Recently, a new method was discovered to enhance the effectiveness of prescribed drugs.

Our attention, our memories, our mind. These things guide us in every moment of every day, consciously and unconsciously. Cognitive function, the ability to learn, solve problems, and use stored information, is key for development and growth. This is why diseases like dementia and other neurological diseases, which affect cognitive function, are so dangerous. Currently, medications remain the first step in treating neurological diseases.

Memories are at the core of being human. No other organism on Earth can think in the past, present, and future the way we can. However, in April of 2023, a team of scientists at the University of Sydney demonstrated that Nanowire Networks, an innate object, can exhibit short-term and long-term memory like the human brain.

The human body is equipped with a line of warriors to combat all types of harmful molecules and substances that the body could encounter. One of the fiercest warriors the body has to offer are T cells. T cells are white blood cells that develop from bone marrow. They play a central role in protecting our body from infection.

Scientists at UC San Diego have developed an extracellular matrix, which is basically a bunch of proteins that work together to surround the heart. Once this matrix surrounds the heart, it protects it from inflammatory cells that would ultimately damage the heart more. In this way, the material reduces inflammation in the heart and encourages the heart to repair its cells, which ultimately helps repair the scarred tissue. The scientists' trial has shown success in both rodents and pigs. This gives the team hope that a human clinical trial will be successful and are looking to start the trial as soon as possible. This treatment is so revolutionary because permanent scarring from a heart attack can occur in under six hours from when a patient first experiences that attack.

Nano is a prefix that means one billionth or 10-9. At this size, we’re talking about the atomic level. Bot, short for robot, is a programmed machine that executes tasks without human involvement. Now imagine the power if we combined these two ideas. That is what makes nanobots, a subset of nanotechnology, so powerful, particularly in the field of medicine where atomic level substances create a system.
