Transmission Of Infectious Diseases During Transcontinental Airline Flight

With over 3 billion airline flight passengers annually, the inflight transmission of infectious diseases is an important global health concern. Over a dozen cases of inflight transmission have documented, and studies of severe acute respiratory syndrome (SARS) and pandemic Influenza (H1N1p) transmission on airplanes indicate that air travel can serve; as a conduit for the…

Impact Of Long-Duration Space Missions On Astronaut Microbiome

The study documented the diversity of microbes associated with astronaut before; during and after long duration space missions at the ISS using culture independent 16S rRNA gene analysis. The evidence presented herein shows that space travel can have both transient; and longer lasting impacts on the microbiome of astronauts; and that these changes are associate…

Carbon dioxide

Effects Of Acute Exposures To Carbon Dioxide On Astronaut

Adverse effects of carbon dioxide (CO2) on cognitive processes have reported; but the effects observed occurred at CO2 concentrations that were considerably higher than those deemed safe by regulatory agencies. However, studies using the Strategic Management Simulation (SMS) test to assess complex decision making demonstrated effects of CO2 on decision-making performance; at or below 2500 ppm, a level that…

Bone loss

Bone Loss In Spaceflight Can Be Prevented By Melatonin

Exposure to microgravity during space flight leads to rapid bone loss in humans and animals. The rapid and vigorous bone loss is one of the key challenges; that remain to be solve to enable humans to pursue healthy lives in outer space. Bone mass often reflects a balance between bone formation; by osteoblasts and bone…

Antimicrobial Coating

Antimicrobial Coating Tested By Astronauts In Space Station

The immune system also takes a beating, leaving us more vulnerable to infection. Astronauts have now tested a new antimicrobial coating on board the International Space Station (ISS); and found it kept the space-faring bugs at bay for well over a year. Humans are not built for space travel the harsh environment messes with our…

Spaceflight Found To Reactivate Dormant Viruses In Astronauts

There are certainly a whole host of technological hurdles to overcome before humans successfully travel to Mars; or beyond, but research is also pointing to a growing assortment of fundamental health challenges; that astronauts may face from long stretches of time in spaceflight. A recent NASA-funded study has found dormant viruses can reactivate in the…

3D-Printed Skin And Bones Grown Are Used By Astonaunts

Astronauts could benefit greatly from 3D bioprinting, which here on Earth; could help surgeons and doctors patch up wounds or even print new functioning organs for transplant. Regular 3D printing has already considered for space travel; helping astronauts make new tools or even shelters out of Mars dust. Life isn’t easy for astronauts living in…

HypoGravity

Cardiopulmonary Response: Ergometer Exercise In HypoGravity Analog

The objective of our research is to investigate and characterize cardiovascular, pulmonary; and musculoskeletal responses (i.e., foot forces) to ergometer exercise in hypogravity conditions (between 0 and 1 g) to fill the gap between those gravitational levels. Astronauts on space missions experience various detrimental physiological effects including (but not limited to) muscular atrophy; diminished cardiopulmonary…

Moss

Stem cells and Space Moss Grow In Space Station

Space Moss is an experiment that pretty much explains itself right there in the name. But if you think astronauts may be noshing on moss during the long trip to Mars; think again it’s actually an experiment to verify that we  do that. The International Space Station is such a unique and important test bed…

Astronauts Do Not Die From Space Radiation Research Says

A study publish in Scientific Reports fail to tell about exposure to space radiation with an increase risk of death; from cancer or cardiovascular disease among both astronauts and cosmonauts. It’s a surprising, if not encouraging, result, as it was long assume that exposure to damaging; ionizing radiation would eventually come back to retreat astronaut;…

Microgravity

Real Microgravity Influences the Cytoskeleton and Focal Adhesions

Due to the high mortality, new ways must be taken to find new approaches and therapeutic strategies in cancer research. Experiments performed in the space environment are not typically the main topic of cancer researchers. However, a stay in orbit on the International Space Station (ISS) provides physical conditions that are not achievable on Earth.…

Air ambulance

Cost Of Emergency Air Lift to Hospital By Air Ambulance Is $40,000

The median charge of an air ambulance lift was $39,000 in 2016; about 60% more than the $24,000 charged just four years earlier; researchers found. That amount is “more than half of the household income for the average American family in 2016,” said lead researcher Ge Bai. She is an associate professor of health policy…
