In 2000, a famous experiment by Dr. Andre Geim demonstrated how a frog could be levitated using diamagnetism, earning an Ig Nobel Prize; this phenomenon showcases how magnetic fields can make living organisms float without harm, with potential applications in research and industry, and hints at future possibilities like human levitation.
NASA's SpaceX 31st commercial resupply mission successfully launched, delivering over 6,000 pounds of supplies and scientific experiments to the International Space Station. The Dragon spacecraft, launched from Kennedy Space Center, will dock with the ISS to support research during Expedition 72, including studies on solar wind, cosmic radiation effects on plants, and cold welding in microgravity. The mission supports NASA's Artemis campaign, preparing for future Moon and Mars expeditions. The Dragon will return to Earth in December with research and cargo.
The Shenzhou-18 crew has been conducting various scientific experiments aboard the China Space Station since April 26, including life science and ecological studies with zebrafish and hornwort, and combustion research. They have observed abnormal behaviors in zebrafish due to microgravity and completed several technical tasks related to combustion and material experiments. The astronauts also perform regular exercises to counteract the physiological effects of microgravity.
The upcoming total solar eclipse in April is expected to provide a unique opportunity for scientific research, with the moon being unusually close to Earth and the sun showing increased activity. Hundreds of thousands of spectators are expected to participate as "citizen scientists," aiding NASA and other research groups in studying the sun's corona, atmospheric changes, and animal behavior during the eclipse. Rockets, high-altitude jets, weather balloons, and even a kite with a science instrument will be deployed to gather data. This eclipse will offer valuable insights into the sun's corona and its extreme temperatures, and it is anticipated to be the best opportunity for scientific observations until 2045.
NASA's Crew-7, including members from the US, Russia, Europe, and Japan, returned to Earth after a 199-day mission aboard the SpaceX Dragon Endurance, contributing to various scientific experiments and spacewalks aimed at preparing for future lunar and Mars missions. The crew's research included studying human response to spaceflight durations and growing food in space, with the goal of benefiting humanity and advancing NASA's Artemis program for deep-space exploration.
NASA-funded projects are gearing up to study the effects of the upcoming total solar eclipse on the ionosphere, a layer of the atmosphere critical for long-distance radio communication. Three experiments, including the Super Dual Auroral Radar Network, Ham Radio Science Citizen Investigation, and RadioJOVE, will use radio technology to investigate changes in the ionosphere's density, temperature, and radio signal propagation during the eclipse. These studies aim to provide valuable insights into how the ionosphere responds to the temporary loss of sunlight and its impact on radio communication.
A YouTube channel, Double M Innovations, conducted an experiment to harvest electricity from high-voltage transmission lines using regular fences, using a capacitor, full bridge rectifier, and coax cable. The results showed the capacitor charging up to 1000 V before the experiment was stopped, indicating the potential to collect significant power from a few kilometers of fencing wire underneath such lines. However, the legal implications of storing the power inductively coupled on fence wire should be discussed with local energy companies.
Axiom Space is set to launch its all-European crew, including Commander Michael López-Alegría, Pilot Walter Villadei, and Mission Specialist Alper Gezeravcı, to the International Space Station on January 17. The crew will conduct over 30 scientific experiments and 50 outreach events during their 14-day mission, with a focus on life science investigations. The mission marks the first Turkish astronaut's journey to space and includes ESA astronaut Marcus Wandt, who will conduct experiments on stem cells. The crew is also bringing small items of significance to themselves and their countries.
NASA and SpaceX have successfully launched the 29th commercial resupply mission to the International Space Station. The cargo includes scientific experiments and technology demonstrations, such as enhanced optical communications and measurement of atmospheric waves. The SpaceX Dragon will also deliver NASA's ILLUMA-T for testing high data rate laser communications and the Atmospheric Waves Experiment to study atmospheric gravity waves. Additionally, the cargo includes respiratory health research, water filtration technology, and hardware for various purposes. These missions contribute to advancements in biology, biotechnology, physical sciences, and Earth and space science, supporting long-duration space travel and future exploration beyond low Earth orbit.
Virgin Galactic has announced that its 'Galactic 05' research mission will open on November 2, 2023, marking the company's sixth spaceflight this year and tenth overall. The mission will convert Virgin Galactic's Spaceship into a suborbital space lab for scientific research, with five experiments planned. The crew will include scientist Dr. Alan Stern and researcher Kellie Gerardi, who will conduct various research activities during the flight. This mission highlights Virgin Galactic's commitment to providing affordable access to space for microgravity and space-based research.
In 1993, Carl Sagan and his team conducted an audacious experiment to search for evidence of life on Earth that could be detected from space. By using NASA's Galileo spacecraft, they found evidence of oxygen, water vapor, ice, and other greenhouse gases, as well as amplitude-modulated waves not known to occur naturally. This experiment, which tested the accuracy and relevance of methods used to detect extraterrestrial life, has since stood the test of time and provided valuable lessons for researchers and science publishers. It emphasizes the importance of testing what we think we know, conducting control experiments, and carefully reporting findings in the search for life beyond Earth.
Physicists at the University of Cambridge have used simulations of hypothetical time travel to solve experimental problems that seem impossible using standard physics. By manipulating quantum entanglement, they showed that retroactively changing past actions can improve outcomes in the present. Although controversial, the study connects their theory to quantum metrology and demonstrates that entanglement can solve seemingly impossible problems. The simulation has a 75% chance of failure, but the researchers propose sending a large number of entangled photons and using a filter to ensure the correct information is obtained. This research provides insights into the fundamentals of quantum mechanics and the potential for improving scientific experiments.
India's Chandrayaan-3 mission successfully landed a spacecraft near the south pole of the moon, becoming the first nation to do so. The mission has deployed the Pragyan rover to explore the lunar surface and has started conducting scientific experiments, including measuring temperature profiles of the moon's south pole soil using the ChaSTE experiment. The mission aims to understand the thermal behavior of the moon's surface. The rover recently encountered a hazardous crater but has safely retraced its path and continues its exploration.
China's Tiangong space station has begun hosting scientific experiments from researchers around the world, as part of China's efforts to engage the global scientific community. The first experimental equipment for joint projects with the United Nations was transported to Tiangong on May 10, according to China's Manned Space Agency project office.
An AI system called BacterAI has enabled robots to conduct up to 10,000 autonomous scientific experiments per day, potentially driving a drastic leap forward in the pace of discovery in areas from medicine to agriculture to environmental science. The system mapped the metabolism of two microbes associated with oral health, discovering the amino acid requirements for the growth of both Streptococcus gordonii and Streptococcus sanguinis. BacterAI creates its own data set through a series of experiments, analyzing the results of previous trials to come up with predictions of what new experiments might give it the most information.
