Space travel can disrupt the functioning of the robust cell barrier that lines our intestines to prevent bacteria, fungi, and viruses from invading the rest of our bodies, according to a study.
Researchers from the University of California (UC), Riverside in the US noted that the microgravity environment encountered in space has profound effects on human physiology, leading to clinical symptoms and illnesses including gastroenteritis.

The study, published in the journal Scientific Reports , has implications for understanding the effects of space travel on the intestinal function of astronauts in space, as well as their capability to withstand the effects of agents that compromise intestinal epithelial barrier function following their return to Earth.

Astronauts' health seen as core part of space station tech - Chinadaily.com.cn
As China advances steadily toward its goal of building a manned space station, the country's medical experts are playing an indispensable role in the grand program, according to a leading scientist.

"We want to investigate how the special environment inside the space station, especially its weightlessness, will affect astronauts' health, particularly their cerebral functions. And we'll explore ways to ensure their health during lengthy missions," he added.
Hungarian in Space: Gov't Plans to Follow in Bertalan Farkas' Legendary Footsteps -
At NASA, 2019 was the year of the woman, yet women still are a big minority at the space agency -
At NASA, 2019 could be called the year of the woman. In October, astronauts Christina Koch and Jessica Meir completed the first all-female spacewalk. Koch also is on her way toward 328 days aboard the International Space Station - the longest single space mission by a woman.
Meanwhile, NASA is planning a lunar mission called "Artemis," named after the twin sister of Apollo, which, the agency says, would put "the next man and the first woman on the moon" by 2024. The aerospace industry also boasts an unprecedented number of women in high-ranking positions, including Leanne Caret, who leads Boeing's defense and space division and Gwynne Shotwell, the president and chief operating officer of SpaceX.

Rocket Report: Cornwall locals protest spaceport, China's toxic rocket problem | Ars Technica
Welcome to Edition 2.24 of the Rocket Report! We have a shorter report this week due to the American holiday of Thanksgiving. But don't worry, there is still plenty of interesting news from the world of lift—from strong anti-spaceport protests in England to continued problem with toxic rocket stages falling on people in China.
Virgin eyes point-to-point travel . Virgin Galactic's new chairman, venture capitalist Chamath Palihapitiya, recently suggested that the company's long-term profitability may come more through travel than space tourism. At the Phocuswright travel industry conference last week, Palihapitiya spoke about his interest in point-to-point travel on Earth, Ars reports .
Welsh university finds astronauts' brains could become 'leaky' during space travel |
Human brains could become 'leaky' during space travel according to research by the University of South Wales.
Professor Damian Bailey found changes in gravity and long-term space flights could weaken the blood-brain barrier that helps protect the brain.
This can then lead to swelling and increased pressure in the brain which, according to Professor Bailey, NASA have identified as "the top health risk for long-duration spaceflight".
Friendswood astronaut returns from space with sense of wonder - Houston Chronicle
Friendswood resident Nick Hague said that it took a couple of days to relearn balance after he returned to Earth from a mission aboard the International Space Station.

For astronaut Nick Hague, it was good to be back home with both feet on the ground in Friendswood, even if his mind was still reeling from the otherworldly nature of his job.
“It’s amazing,” he said. “The re-adaptation (to earth) has made me realize how miraculous our bodies are.”
Reaction Engines' Hybrid Engine for Revolutionary Hypersonic Air Travel and Space Access

While airplane engines have become quite efficient over recent decades, rocket engine technology has not progressed significantly in 70 years. Reaction Engines is a company looking to push both types of propulsion technology forward by merging an airplane engine and a rocket engine in one system to create a hybrid hypersonic engine. The result is a light, powerful system called the Synergetic Air-Breathing Rocket Engine (SABRE), which could open the door to more sustainable aviation.
