As astronauts venture further into space, their exposure to harmful radiation rises. Researchers from Columbia University are simulating the effects of space radiation here on Earth to determine its impact on human physiology using multi-organ tissue chips. Their work documents the differential effects seen in tissues after acute and prolonged radiation exposure and identifies multiple genes of interest that could help inform the development of future radioprotective agents.

Their study appears in Advanced Science.

“As deep space exploration continues to unfold, it is vital to understand the physiological damage caused by space radiation to better mitigate its effects. By exposing multi-organ models to simulated cosmic radiation, this study has laid the groundwork to aid in this effort,” commented Jermont Chen, Ph.D., a program director in the Division of Discovery Science and Technology at NIBIB.

The Russian Ministry of Health has announced that it has developed a vaccine against cancer that will be distributed to Russian patients for free from early 2025.

According to TASS, the Russian state-owned news agency, Andrey Kaprin—the General Director of the Radiology Medical Research Center of the Russian Ministry of Health—recently announcement the development on Russian radio.

The vaccine will apparently be used to treat cancer patients, rather than given to the general public to prevent cancer—and it will be personalized to each patient.

People with breathing problems during sleep may have a larger hippocampus, the area of the brain responsible for memory and thinking, according to a study published in the December 18, 2024, online issue of Neurology.

The study, which included mostly Latino people, also found that those with lower oxygen levels during sleep had changes in the deep parts of the brain, the white matter, a common finding of decreased brain health that develops with age.

Sleep disordered breathing is a range of conditions that cause abnormal breathing during sleep, including snoring and obstructive sleep apnea. Obstructive sleep apnea is when a person stops breathing five or more times per hour. When breathing stops, it can lower oxygen levels, affecting the brain.

A NASA-led study reveals that the pattern of rainfall throughout the year—specifically the frequency and intensity of rain events—is nearly as significant to global vegetation health as the total amount of annual rainfall.

The research indicates that less frequent but heavier rainfalls can benefit plants in arid regions like the U.S. Southwest, while potentially harming those in wetter ecosystems such as the Central American rainforests due to longer intervals of dryness.

DDW Editor Reece Armstrong speaks to Ellie Mahjubi, Vice President, Protein and cell analysis at Thermo Fisher Scientific, about how spatial biology is impacting drug discovery and development research.

RA: What’s the future and potential for spatial biology?

EM: Technological advancements in spatial biology are providing unprecedented insights into single cells within their spatial context, facilitating the analysis of cell types, functional states, cell interaction networks, as well as tissue microenvironments and architecture. These innovations promise to significantly advance basic research and enhance our understanding of human health and disease.

Nearly a quarter of Portuguese adults have allergies that cause a runny nose. This respiratory disease, formally called allergic rhinitis and frequently associated with asthma, is a common problem around the world, and the upper airway is a key target for research into the underlying disease processes.

Now a global team of researchers has discovered that patients with allergy-induced sniffles and asthma have different fungal colonies or mycobiomes in their noses, suggesting potential lines of inquiry for future treatments.

“We showed that allergic rhinitis samples displayed a significantly higher fungal diversity and a different fungal community structure compared to those of healthy controls,” said Dr. Luís Delgado of the University of Porto, Portugal, one of the authors of the article in Frontiers in Microbiology. “This may suggest that allergic rhinitis increases the diversity and changes the composition of the upper airway’s microbiome.”

IVF technology matures eggs in a culture of iPSC (induced stem cell)-derived ovarian cells.

A baby was born in their trial, marking “first ever human birth using using iPSC technology” company claims.

Gameto useds iPSCs, or induced pluripotent stem cells. Same as embryonic stem cell, except made by inducing (forcing) a skin cell or white blood from a donor cell to become a stem cell using a protein cocktail. Dont need embryo to start.

The findings suggest that biochemical and physical effects of exercise could help heal nerves. There’s no doubt that exercise does a body good. Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system.

Now, MIT engineers have found that exercise can also have benefits at the level of individual neurons. They observed that when muscles contract during exercise, they release a soup of biochemical signals called myokines. In the presence of these muscle-generated signals, neurons grew 4X farther compared to neurons that were not exposed to myokines. These cellular-level experiments suggest that exercise can have a significant biochemical effect on nerve growth.

Surprisingly, the researchers also found that neurons respond not only to the biochemical signals of exercise but also to its physical impacts. The team observed that when neurons are repeatedly pulled back and forth, similarly to how muscles contract and expand during exercise, the neurons grow just as much as when they are exposed to a muscle’s myokines.

Trying to stay healthy into old age is a better goal than attempting to live as long as possible.
