Astronaut study reveals effects of space travel on human bones

A study of bone loss in 17 astronauts who flew aboard the International Space Station is providing a fuller understanding of the effects of space travel on the human body and steps that can mitigate it, crucial knowledge ahead of potential ambitious future missions.

The research amassed new data on bone loss in astronauts caused by the microgravity conditions of space and the degree to which bone mineral density can be regained on Earth. It involved 14 male and three female astronauts, average age 47, whose missions ranged from four to seven months in space, with an average of about 5-1/2 months.

A year after returning to Earth, the astronauts on average exhibited 2.1 percent reduced bone mineral density at the tibia – one of the bones of the lower leg – and 1.3 percent reduced bone strength. Nine did not recover bone mineral density after the space flight, experiencing permanent loss.

“We know that astronauts lose bone on long-duration spaceflight. What's novel about this study is that we followed astronauts for one year after their space travel to understand if and how bone recovers,” said University of Calgary professor Leigh Gabel, an exercise scientist who was the lead author of the research published this week in the journal Scientific Reports https://www.nature.com/articles/s41598-022-13461-1.

“Astronauts experienced significant bone loss during six-month spaceflights – loss that we would expect to see in older adults over two decades on Earth, and they only recovered about half of that loss after one year back on Earth,” Gabel said.

The bone loss occurs because bones that typically would be weight-bearing on Earth do not carry weight in space. Space agencies are going to need to improve countermeasures – exercise regimes and nutrition – to help prevent bone loss, Gabel said.

“During spaceflight, fine bone structures thin, and eventually some of the bone rods disconnect from one another. Once the astronaut comes back to Earth, the remaining bone connections can thicken and strengthen, but the ones that disconnected in space can't be rebuilt, so the astronaut's overall bone structure permanently changes,” Gabel said.

The study's astronauts flew on the space station in the past seven years. The study did not give their nationalities but they were from the U.S. space agency NASA, Canadian Space Agency, European Space Agency and Japan Aerospace Exploration Agency.

Space travel poses various challenges to the human body – key concerns for space agencies as they plan new explorations. For instance, NASA is aiming to send astronauts back to the moon, a mission now planned for 2025 at the earliest. That could be a prelude to future astronaut missions to Mars or a longer-term presence on the lunar surface.

“Microgravity affects a lot of body systems, muscle and bone being among them,” Gabel said.

“The cardiovascular system also experiences many changes. Without gravity pulling blood towards our feet, astronauts experience a fluid shift that causes more blood to pool in the upper body. This can affect the cardiovascular system and vision.

“Radiation is also a large health concern for astronauts as the further they travel from Earth the greater exposure to the sun's radiation and increased cancer risk,” Gabel said.

The study showed that longer space missions resulted both in more bone loss and a lower likelihood of recovering bone afterward. In-flight exercise – resistance training on the space station – proved important for preventing muscle and bone loss. Astronauts who performed more deadlifts compared to what they usually did on Earth were found to be more likely to recover bone after the mission.

“There is a lot we still do not know regarding how microgravity affects human health, particularly on space missions longer than six months, and on the long-term health consequences,” Gabel said. “We really hope that bone loss eventually plateaus on longer missions, that people will stop losing bone, but we don't know.”

At the Indonesia International Book Fair 2024, TRENDS inaugurates 10th global office, releases four books

As part of its Asian research tour, partnership with Aletihad News Center, and
primary sponsorship of the Indonesia International Book Fair 2024, TRENDS
Research & Advisory inaugurated its office in Jakarta, marking its 10th location
worldwide. It also released four books in Indonesian.
The inauguration event was attended by ambassadors of the UAE, Bahrain, and
Jordan to Indonesia, chairpersons of the UAE and Indonesian Publishers’
Associations, the Director of TRENDS’ Jakarta office, and a group of researchers
and academics.
Speaking at the event, Dr. Mohammed Abdullah Al-Ali, CEO of TRENDS
Research & Advisory, stated that TRENDS’ international offices—set to reach 15
by the end of 2024—aim to enhance the Center’s research efforts and deepen its
role in disseminating knowledge, thus serving as a global knowledge bridge.
He emphasized, “At TRENDS, we believe in the importance of cooperation
between think tanks and prioritize this endeavor. We believe the TRENDS office in
Jakarta will enhance the exchange of knowledge and ideas between think tanks in
Asia and the Middle East, opening new horizons for collaboration in various
fields.”

Four books in Indonesian
As part of the Jakarta office’s inaugural activities, four books were released in
Indonesian, including the 11th and 12th books of the Muslim Brotherhood
Encyclopedia and Global Trends in AI and Automation and the Future of
Competition between Man and Machine: An Analytical Forward-looking Vision.

Hostility to Arab states
The 11th book of the Muslim Brotherhood Encyclopedia, The Concept of the State
According to the Muslim Brotherhood, highlights its hostile stance toward Arab
states since its inception. The group views them as an obstacle to its ascent to
power. It opposed the modern principles upon which these states were built,
considering them incompatible with the group’s unique interpretation of Islam,
which it claimed to embody exclusively.

Exclusion of nonconformists
The 12th book, The Muslim Brotherhood: Rejection of Tolerance and Exclusion of
Nonconformists, examines the Muslim Brotherhood’s stance towards
nonconformists, individuals, and entities. The book reveals the group’s binary view
of the world, categorizing others as allies or adversaries. It ties these relationships
to the Brotherhood’s internal power struggles and self-serving interests.

Global Trends in AI
The third book, Global Trends in AI, explores significant developments in AI and
its impact on various aspects of life, including the economy, society, and
governance. It also offers a comprehensive analysis of technological advancements
in AI, its applications across sectors, the ethical and social challenges it presents,
and its future trajectory.

US determined to prevent full-scale war in Middle East, Joe Biden tells UNGA79

US President Joe Biden highlighted the US Administration’s determination to prevent a wider war that engulfs the entire Middle East region, noting that a diplomatic solution “remains the only path to lasting security to allow the residents from both countries to return to their homes on the border safely”.

In remarks he made today before the 79th Session of the United Nations General Assembly (UNGA79), the US President said, “Full-scale war is not in anyone’s interest,” adding that a diplomatic solution is still possible.

He also touched on “the rise of violence against innocent Palestinians on the West Bank”, and the need to “set the conditions for a better future”, which he said featured “a two-state solution, where the world — where Israel enjoys security and peace and full recognition and normalised relations with all its neighbours, where Palestinians live in security, dignity, and self-determination in a state of their own”.

President Biden underscored the ceasefire and hostage deal put forth by Qatar and Egypt, which the UN Security Council endorsed. He said, “Now is the time for the parties to finalise its terms, bring the hostages home,” adding that this would help ease the suffering in Gaza, and end the war.
