Dr. Ana Diaz Artiles: “When we’re upright, a large part of our fluids are stored in our legs, but in microgravity we get a redistribution of fluids into the upper body.”

What physiological effects can extended periods of microgravity have on the human eye? This is what a recent study published in npj Microgravity hopes to address as a team of researchers investigated how the shifting of fluids under microgravity conditions could lead to eye vessel alterations. This study holds the potential to help space agencies, researchers, and the public better understand the short-and long-term physiological effects of microgravity, specifically with more humans traveling beyond Earth’s gravity on commercial spaceflights.

“When we experience microgravity conditions, we see changes in the cardiovascular system because gravity is not pulling down all these fluids as it typically does on Earth when we are in an upright position,” said Dr. Ana Diaz Artiles, who is an assistant professor in the Department of Aerospace Engineering at Texas A&M University and a co-author on the study. “When we’re upright, a large part of our fluids are stored in our legs, but in microgravity we get a redistribution of fluids into the upper body.”

Researchers at the National Institutes of Health (NIH) have developed a non-chemotherapy treatment regimen that is achieving full remissions for some people with aggressive B-cell lymphoma that has come back or is no longer responding to standard treatments. The five-drug combination targets multiple molecular pathways that diffuse large B-cell lymphoma (DLBCL) tumors use to survive.

In a clinical trial at NIH’s National Cancer Institute (NCI), researchers tested the combination of venetoclax, ibrutinib, prednisone, obinutuzumab, and lenalidomide (called ViPOR) in 50 patients with DLBCL, the most common type of lymphoma. The treatment shrank tumors substantially in 26 of 48 (54%) evaluable patients, with 18 (38%) of those patients’ tumors disappearing entirely, known as a complete response. At two years, 36% of all patients were alive and 34% were free of disease. These benefits were seen mainly in people with two specific subtypes of DLBCL.

The findings were published June 20, 2024, in the New England Journal of Medicine.

The breakthrough clears the way for smarter, more agile nanotech.

Dr. Ben Murnane has published an Opinion piece in FEE, the Foundation for Economic Education, a major US think thank. The essay covers #transhumanism and the new biography Transhuman Citizen, out in 10 days.

It’s telling that with the rise of AI the first instinct of many politicians is to regulate it.

Is our brain responsible for how we react to people who are different from us? Why can’t people with autism tell lies? How does the brain produce empathy? Why is imitation a fundamental trait of any social interaction? What are the secret advantages of teamwork? How does the social environment influence the brain? Why is laughter different from any other emotion?

This course is aimed at deepening our understanding of how the brain shapes and is shaped by social behavior, exploring a variety of topics such as the neural mechanisms behind social interactions, social cognition, theory of mind, empathy, imitation, mirror neurons, interacting minds, and the science of laughter.
