Spores

Spores in Space: Mold Can Withstand Radiation Doses

Having fungus among us in space could be a plus. Mold can be use to produce compounds in antibiotics, for example, and space medicine could come in handy. But the results of the new research also raise concerns, Cortesão said in the AGU statement; because the fungi withstood radiation exposure 200 times the dose that…

Nauseous

Cabin Crew, Pilots and Passengers Are Feeling Nauseous

European aircraft manufacturer Airbus and TAP Air Portugal are investigating reports the new A330neo aircraft; is causing cabin crew, pilots and passengers to feel nauseous and sick and even pass out in some rare cases.  According to the Portuguese newspaper Publico; a number of complaints have made to the National Civil Aviation Authority; and that…

Muscle Loss

New Objective to Reduce Muscle Loss During Spaceflight

Astronauts often suffer from muscle loss during the long space mission. It’s called atrophy, and NASA says that astronauts can lose up to 20% muscle mass during missions of only 5 to 11 days. This muscle loss affects what are called “anti-gravity muscles,” including calf muscles; the quadriceps and the muscles of the back and neck.…

Biomedical engineering

Space Biomedical Engineering Used For A Healthy Life

Scientists are charged with developing advanced life-support machines; inside the biomedical engineering labs at NASA to help astronauts breathe for longer in space. Others have developed custom equipment space gyms; in a sense enabling astronauts to complete full-body workouts on the International Space Station; exercise helps counteract the perpetual problem of microgravity causing accelerated bone…

Aviation medicine

Aviation Medical Centre And Air Traffic Controllers Launched

To support the health needs of Singapore’s aviation workforce, a new centre was launch at the Changi General Hospital. It will cater to pilots, air traffic controllers as well as ground support staff. Called the Changi Aviation Medicine Centre (CAMC), it is Singapore’s first aviation medicine centre; to be establish within a government restructured hospital.…

Anti-aging

Anti-Aging Effects Of Long-Term Space Missions

Anti-aging effects apply to astronauts during long-term missions in space is investigate herein by analyzing heart rate variability (HRV); on quiet versus magnetically-disturbed days. Exposure to weak geomagnetic fields is associate with biological effects. Previously we showed that magnetic disturbances suppress HRV primarily in the very-low frequency region; which is clinically important since its reduction…

Immune system

Effects Of Microgravity And Other Space Stressors In Immunosuppression

Studies have demonstrate that microgravity and low fluid shear dynamics associate with microgravity play a role in regulation of microbial gene expression, physiology, and even pathogenesis. Exposure of astronauts to acceleration/deceleration, cosmic radiation, and microgravity results in stressors contributing to the dysregulation of immune  system and endocrine system. Other stressors include social separation, confinement, sleep…

Physiological And Psychological Impacts In Long-Duration Spaceflight

Future long-duration missions will be conduct with knowledge obtain from the LEO missions and the lunar landings of 50 years ago. Scientific knowledge from life sciences research and aerospace medicine practice provides a wealth of knowledge; on physiological and psychological issues in outer space to practitioners,crew members and mission designer’s today. Selection of appropriate individuals…

Space motion sickness

Ways To Reduce Space Motion Sickness Among Astronauts

Space motion sickness is defining as the combination of signs and symptoms, including nausea, vomiting; sweating, lack of well-being, decreasing mental and physical performance, disorientation, and drowsiness. These symptoms can occur with the introduction of a new type of real or virtual motion environment; as experienced when travelling in a car or on a boat,…

Neuro-Ocular syndrome

Spaceflight-Associated Neuro-Ocular Syndrome

Unusual physiological and pathological neuro-ocular syndrome in astronauts during and following long duration space flight; were record by The National Aeronautics and Space Administration’s (NASA) Space Medicine Division. These findings include optic disc swelling, globe flattening, choroidal folds, and hyperopic shifts in refraction. Cephalad fluid shift has been propose as a possible unifying etiology; but…

Sleepiness

Sleepiness Among Pilots And HEMS Crew Members In Air Ambulance Service

To maintain around the clock operations; a large portion of the workforce must be organize in shift work and often works extend hours. Shift work can generally be denote as work outside normal daytime; and may include work during evening, night, and weekend. Work during the natural night often influence sleep and functioning and may…

Muscle Loss

Researchers Learned How To Combat Muscle Loss During Space Flights

A new study from The University of Texas Medical Branch at Galveston; has further document how muscles are affect, by reduce gravity conditions during space flight missions and uncover how exercise and hormone treatments; can be tailor to minimize muscle loss for individual space travelers. The findings are available in PLOS One. NASA has recently announce…
