Getting seven experiments on the International Space Station requires a really good idea. Like a brand new way to attack tumors—one that you can only make in space.

Space has unique advantages for making medicines. Its very makes it possible to grow molecules in shapes and uniformity that are difficult to create on Earth. If they can be reliably and affordably produced, such molecules could have all kinds of novel uses in industry and medicine.

University of Connecticut engineer Yupeng Chen has been growing one such unusually rod-shaped nanoparticle, called a Janus base nanotube, on the International Space Station (ISS).

Summary: New research highlights a critical link between antibodies produced against Epstein-Barr virus (EBV) and the development of multiple sclerosis (MS). Scientists discovered that these viral antibodies mistakenly target a protein called GlialCAM in the brain, triggering autoimmune responses associated with MS.

The study also revealed how combinations of genetic risk factors and elevated viral antibodies further increase the risk of developing MS. These insights may pave the way for improved diagnostics and targeted therapies, enhancing our understanding of the genetic and immunological interplay underlying this debilitating disease.

Although it’s not the first time this was hypothesized, this study is the first time researchers looked at the presence of gingipains within the brains of diseased patients. Even more, the patients themselves were never even diagnosed with Alzheimer’s.

“Our identification of gingipain antigens in the brains of individuals with AD and also with AD pathology but no diagnosis of dementia argues that brain infection with P. gingivalis is not a result of poor dental care following the onset of dementia or a consequence of late-stage disease, but is an early event that can explain the pathology found in middle-aged individuals before cognitive decline,” the authors explained.

While this isn’t a one-size-fits-all answer to what causes Alzheimer’s, it’s a step in the right direction to finding the reasoning behind this life-altering disease.

Prostate cancer statistics can look scary: 34,250 U.S. deaths in 2024. 1.4 million new cases worldwide in 2022. Dr. Bruce Montgomery, a UW Medicine oncologist, hopes that patients won’t see these numbers and just throw up their hands in fear or resignation.

“Being diagnosed with is not a death knell,” said Montgomery, senior author of a literature and trial review that appeared in JAMA today. Montgomery is the clinical director of Genitourinary Oncology at Fred Hutch Cancer Center and University of Washington Medical Center, and a professor of medicine and urology at the UW School of Medicine.

He encourages patients to ask their primary-care doctor specific questions about this cancer too. Montgomery also encourages his fellow doctors to bring up the question of prostate cancer screening with their patients.

Researchers at the Francis Crick Institute have identified genetic changes in blood stem cells from frequent blood donors that support the production of new, non-cancerous cells.

Understanding the differences in the mutations that accumulate in our as we age is important to understand how and why blood cancers develop and hopefully how to intervene before the onset of clinical symptoms.

As we age, stem cells in the bone marrow naturally accumulate mutations and with this, we see the emergence of clones, which are groups of blood cells that have a slightly different genetic makeup. Sometimes, specific clones can lead to like leukemia.

Twenty years after the first publication that used the term microplastic, we review current understanding, refine definitions, and consider future prospects. Microplastics arise from multiple sources, including tires, textiles, cosmetics, paint, and the fragmentation of larger items. They are widely distributed throughout the natural environment, with evidence of harm at multiple levels of biological organization. They are pervasive in food and drink and have been detected throughout the human body, with emerging evidence of negative effects. Environmental contamination could double by 2040, and wide-scale harm has been predicted. Public concern is increasing, and diverse measures to address microplastic pollution are being considered in international negotiations.

Getting seven experiments on the International Space Station requires a really good idea. Like a brand new way to attack tumors—one that you can only make in space.

Space has unique advantages for making medicines. Its very low gravity makes it possible to grow molecules in shapes and uniformity that are difficult to create on Earth. If they can be reliably and affordably produced, such molecules could have all kinds of novel uses in industry and medicine.

University of Connecticut engineer Yupeng Chen has been growing one such unusually rod-shaped nanoparticle, called a Janus base nanotube, on the International Space Station (ISS). The success of Chen’s last five experiments has led to this latest $1.9 million award from the Center for Advancement of Science in Space and NASA’s Division of Biological and Physical Sciences. With it, Chen and his colleagues will use the space station’s unique environment to grow pharmaceuticals whose shape is their secret weapon.#

Experiments aboard the International Space Station may offer promising advancements in fighting cancer.

Below is an overview of a developing cancer treatment that relies on highly focused sound waves in a liquid medium (often the body’s own fluids) to non-invasively destroy tumors. Though the technology is still in various stages of research and clinical trials, it shows promise as a potential alternative or complement to surgery, radiation, or traditional chemotherapy.

1. What Is This Technology?

A primary example of a soundwave-based treatment that uses water or fluid in the body is called histotripsy (or, more broadly, high-intensity focused ultrasound—HIFU). Histotripsy is an emerging therapy that directs ultra-short, high-intensity ultrasound pulses at a targeted area, causing microscopic, rapid changes in tissue pressure.

A recent study by the Hector Institute for Translational Brain Research (HITBR) at the Central Institute of Mental Health (CIMH) in Mannheim provides the first detailed cellular insights into how psilocin, the active ingredient in magic mushrooms, promotes the growth and networking of human nerve cells.

These findings complement clinical studies on the treatment of mental disorders and could contribute to a better understanding of the neurobiological mechanisms behind the therapeutic effect of psilocybin.

Psilocybin is the well-known in so-called magic mushrooms, which is converted in the body to psilocin—the compound that ultimately unleashes the psychoactive effect. The Mannheim research team worked directly with psilocin to investigate the neurobiological effects.
