How Space Flight Alters Kidney Structure and Function

Posted by in categories: biotech/medical, health

How can long-term space flight influence astronaut health, and specifically their organs? This is what a recent study published in Nature Communications hopes to address as a large team of international researchers conducted the most comprehensive study regarding astronaut kidney health and how it’s affected from both microgravity and galactic cosmic radiation (GCR) during long-term space missions. This study holds the potential to help astronauts, space agencies, medical professionals, and the public better understand the health risks associated with sending humans to other worlds, specifically to Mars.

“We know what has happened to astronauts on the relatively short space missions conducted so far, in terms of an increase in health issues such as kidney stones,” said Dr. Keith Siew, who is a Research Fellow in the Department of Renal Medicine at the University of College London (UCL) and lead author of the study. “What we don’t know is why these issues occur, nor what is going to happen to astronauts on longer flights such as the proposed mission to Mars.”

Aside from the 24 Apollo astronauts who traveled to the Moon, with 12 of them walking on the surface, nearly all human space travel has been limited to low-Earth orbit (LEO), totaling almost 700 people having traveled to space. During this time, they are protected by the Earth’s magnetic field, which shields them from harmful solar and cosmic radiation that could cause potentially irreparable harm to their health.

New technique could help build quantum computers of the future

Posted by in categories: health, quantum physics, robotics/AI, supercomputing

Quantum computers have the potential to solve complex problems in human health, drug discovery, and artificial intelligence millions of times faster than some of the world’s fastest supercomputers. A network of quantum computers could advance these discoveries even faster. But before that can happen, the computer industry will need a reliable way to string together billions of qubits—or quantum bits—with atomic precision.

The Physics of Failure: Analyzing Hubble’s Gyroscope Malfunction

Posted by in categories: health, physics, space

The Hubble Space Telescope is currently in safe mode due to gyroscope problems, suspending its science activities. However, NASA remains optimistic about its future contributions to space exploration, working in tandem with other telescopes.

On May 24, NASA’s Hubble Space Telescope entered safe mode due to an ongoing gyroscope (gyro) issue, suspending science operations. Hubble’s instruments remain stable, and the telescope is in good health.

The telescope automatically entered safe mode when one of its three gyroscopes returned faulty telemetry readings. Hubble’s gyros measure the telescope’s slew rates and are part of the system that determines and controls precisely the direction the telescope is pointed.

How psychedelics could help silence chronic pain

Posted by in categories: biotech/medical, health, neuroscience

What if symptoms of chronic pain were sometimes just echoes of a past injury, and your brain could “snap out of it” with the help of psychedelics? It’s a surprising theory that several labs around the world are beginning to investigate. While there have been few double-blind, placebo-controlled, randomized clinical trials evaluating the efficacy of psychedelics for treating chronic pain, preliminary evidence is beginning to emerge — with promising results.

Chronic pain is defined as pain that persists beyond the usual recovery period or occurs with another condition. It may occur continuously or happen off and on. The most common manifestations of chronic pain are lower back pain, headache disorders, fibromyalgia, and neuropathic pain. People treated for chronic pain often undergo “pain management programs” that combine approaches from different fields to customize treatments.

Although it may be a reflection of ongoing physical health issues, chronic pain can also have deeply psychosomatic origins, reflecting the close relationship between mind and body.

Impossible is nothing: Spanish engineers build combustion engine with no exhaust emissions

Posted by in categories: health, sustainability, transportation

Spanish scientists are working on an internal combustion engine that does not pollute the environment. Will the new technology change the future of emission-free transport, which until now has been associated with electrification? Two prototypes will soon be presented.

Until recently, it seemed that combustion vehicles, alongside EVs and vehicles that use biofuels, were not participating in the ongoing ‘race’ for sustainable transport. But this has changed, thanks to Spanish scientists from the Technical University of Valencia (Universitat Politècnica de València, UPV) who are working on an emission-free internal combustion engine.

The Spanish scientists have designed a ‘revolutionary’ internal combustion unit that does not generate gases that are harmful to health or carbon dioxide (CO2), and which also stands out for its high efficiency and complies with the emission regulations planned for 2040. According to the Valencian Innovation Agency, which co-financed the project, the first two prototype engines will come to light in the coming months.

New Study Unveils Serotonin’s Key Role in Fertility and Depression

Posted by in categories: biotech/medical, health, neuroscience

Scientists from Nagoya University in Japan have identified the role of serotonin neurons in linking glucose availability to reproductive health. Their research demonstrates how elevated glucose levels stimulate serotonergic neurons, leading to the release of serotonin, which in turn activates kisspeptin neurons responsible for reproductive hormone release. These findings explain why poor nutrition affects fertility and suggest potential treatments for depression-induced infertility through the use of selective serotonin reuptake inhibitors (SSRIs).

Scientists from Nagoya University in Japan have clarified the connection between energy levels and fertility in both animals and humans. They discovered that signaling from serotonin neurons plays a crucial role in maintaining reproductive function by detecting glucose availability, which in turn enhances the release of the reproductive hormone gonadotropin. These findings also offer an explanation for the reduced fertility seen in individuals with depression and suggest potential treatments. The study was published in Scientific Reports.

People who lack sufficient nutrition encounter problems with their reproductive health. For example, ballet dancers can experience menstrual disruptions, and women who fast can struggle to conceive. According to a new study led by Designated Associate Professor Sho Nakamura and Professors Hiroko Tsukamura and Satoshi Ohkura, one of the main factors that affect a person’s reproductive health is glucose availability.

Cesarean Section Reduces Measles Vaccine Efficacy

Posted by in categories: biotech/medical, health

Cesarean section or C-section is a surgical procedure that delivers a baby through an abdominal incision. It is commonly used when the physicians believe it is a safer route for the parent, baby, or both. Cesarean section has appeared throughout history including Ancient Greece, India, Egypt, and Rome. There are even passages on cesarean section in different religious texts. It is believed that the name was attributed to the way Juluis Caesar was born. However, in Ancient Rome a cesarean section was only performed if at the time of birth, the mother was fatally ill and could not deliver naturally. It has been recorded that Julius Caesar’s mother was present during his life, therefore, historians believe he was not delivered through a cesarean section. Medical historians now believe the term originated from a decree in which Julius Caesar ordered women fated by birth to have a cesarean section which in Latin is “Caesones”. To this day, it is still incompletely understood where the name originated.

Cesarean sections are now routinely performed, and the procedure is well established. Interestingly, long-term effects of cesarean sections are not well known. Previously physicians noted no difference in health outcomes between children born through vaginal birth or cesarean section. Recently, however, a research group at the University of Cambridge found that a single dose of the measles vaccine is 2.6 times more likely to not be effective in children born through cesarean section. Unfortunately, a lack of vaccine efficacy leads to weakened immunity due to an inadequate number of antibodies produced to fight infection. While the first vaccination produced little efficacy, researchers demonstrated that a second measles vaccine was comparable to vaginally born children. More specifically, the vaccine was effective and produced the necessary antibodies to fight infection.

The recent paper published in Nature Microbiology by Dr. Henrik Salje, concluded the long-term effects of cesarean section delivery. Researchers suggest an increased risk of measles outbreak among children that were born through cesarean section and had only one measles vaccination. Salje and others explain that lack of vaccine efficacy is linked to the infants’ gut microbiome. It is well established that children receive great exposure to healthy microbes through vaginal birth, which boosts their immune systems. By avoiding microbe exposure through cesarean section, the infant loses critical immune protection.
