# International Space Station National Lab Advances Cardiac and Genetic Research

The International Space Station (ISS) has long been a symbol of human achievement in space exploration, but its role extends far beyond serving as a platform for astronauts to live and work in space. The ISS also functions as a unique laboratory for scientific research, providing a microgravity environment that enables groundbreaking studies across various fields. One of the most promising areas of research conducted aboard the ISS is in the fields of cardiac and genetic science, where the absence of gravity offers new opportunities to explore biological processes in ways that are not possible on Earth.

## The ISS National Lab: A Unique Research Environment

The ISS National Lab is a U.S. government-designated laboratory that supports research and technology development across a wide range of disciplines, including biology, physics, materials science, and medicine. Managed by the Center for the Advancement of Science in Space (CASIS), the ISS National Lab provides access to the unique conditions of low Earth orbit (LEO), where microgravity, radiation, and other space-related factors can influence biological and physical systems in ways that are not yet fully understood.

Microgravity, in particular, plays a critical role in the ISS’s ability to advance cardiac and genetic research. On Earth, gravity exerts a constant force on cells, tissues, and organs, influencing how they grow, develop, and function. In the microgravity environment of space, these forces are drastically reduced, allowing researchers to observe how biological systems behave when freed from the constraints of gravity. This can lead to new insights into the mechanisms of disease, the development of new therapies, and the potential for personalized medicine.

## Cardiac Research in Space: Understanding the Heart in Microgravity

Cardiovascular health is a major area of focus for researchers working aboard the ISS. The heart, like other muscles in the body, is affected by the absence of gravity. In space, the heart does not have to work as hard to pump blood throughout the body, leading to changes in heart muscle structure and function. These changes can provide valuable information about how the heart responds to stress and how cardiovascular diseases develop.

One of the key areas of cardiac research on the ISS involves studying the effects of microgravity on heart cells, or cardiomyocytes. Researchers have been able to grow human heart cells in space and observe how they behave in a microgravity environment. These studies have revealed important insights into how heart cells contract, how they communicate with each other, and how they respond to stress.

For example, a study conducted by researchers from Stanford University and the University of California, San Francisco, used the ISS to grow human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) in microgravity. The researchers found that the cells exhibited changes in gene expression, structure, and function compared to cells grown on Earth. These findings could have important implications for understanding how the heart adapts to long-term spaceflight and for developing treatments for heart disease on Earth.

Additionally, the ISS has been used to study the effects of spaceflight on astronauts’ cardiovascular systems. Astronauts often experience changes in heart rate, blood pressure, and blood volume during space missions, and these changes can provide valuable information about the long-term effects of space travel on the heart. Understanding these effects is crucial for ensuring the health and safety of astronauts on future missions to the Moon, Mars, and beyond.

## Genetic Research: Unlocking the Secrets of DNA in Space

In addition to cardiac research, the ISS National Lab has become a hub for genetic research, particularly in the areas of gene expression, DNA repair, and the effects of radiation on genetic material. The microgravity environment of the ISS offers a unique opportunity to study how genes are regulated and how cells respond to the stresses of spaceflight.

One of the most significant genetic research projects conducted aboard the ISS was NASA’s “Twin Study,” which involved astronaut Scott Kelly and his twin brother, Mark Kelly. Scott Kelly spent nearly a year aboard the ISS, while Mark remained on Earth as a control subject. The study allowed researchers to compare the genetic, physiological, and psychological effects of long-duration spaceflight on Scott with those of his twin brother.

The Twin Study revealed several important findings related to gene expression and DNA. For example, researchers observed changes in Scott Kelly’s telomeres—protective caps on the ends of chromosomes that shorten with age. Surprisingly, Scott’s telomeres lengthened during his time in space, though they returned to their preflight length after his return to Earth. This finding has raised new questions about the effects of spaceflight on aging and cellular health.

Another area of genetic research on the ISS involves studying how cells repair DNA damage caused by space radiation. Space radiation is more intense than the radiation we experience on Earth, and it can cause damage to DNA that may lead to cancer and other diseases. By studying how cells repair this damage in space, researchers hope to develop new strategies for protecting astronauts on long

# Velvety Roasted Butternut Squash Soup with Feta Cheese

As autumn leaves start to fall and the air grows brisk, there’s nothing more comforting than a steaming bowl of soup. One of the season’s most charming delights is velvety roasted butternut squash soup, a dish that not only soothes the body but also excites the palate.

## The Charm of Butternut Squash

Butternut squash is a winter variety that is cherished for its sweet, nutty taste and silky texture. It is loaded with essential nutrients, such as vitamins A and C, potassium, and dietary fiber, making it a nutritious option for any meal. Roasting the squash amplifies its inherent sweetness and introduces a richness of flavor that is irresistible.

### Nutritional Advantages

Beyond its deliciousness, butternut squash is a nutritional marvel. Here are some of its health advantages:

## Ingredients for Velvety Roasted Butternut Squash Soup

To prepare a delectable velvety roasted butternut squash soup with feta cheese, gather the following ingredients:

### For the Soup:
– 1 medium butternut squash (approximately 2-3 pounds), peeled, seeded, and diced
– 1 medium onion, diced
– 2 cloves garlic, minced
– 4 cups vegetable or chicken stock
– 1 cup coconut milk or heavy cream
– 2 tablespoons olive oil
