The free-fall of orbital spaceflight effectively removes the gravitational vector used as a primary spatial orientation reference on Earth. Sustained absence of this reference drives adaptive changes in the internal perception-action models of the central nervous system (CNS), most notably in the processing of the vestibular otolith inputs.

Increased arrivals by air and urbanization are the leading factors leading to a growing vulnerability to pandemics in our cities, a University of Sydney research team has found.
Using the infrared satellite AKARI, a research team has detected the existence of water in the form of hydrated minerals in some asteroids for the first time. This discovery will contribute to our understanding of the distribution of water in our solar system, the evolution of asteroids, and the origin of water on Earth.
With a new crew arriving at the International Space Station, astronauts will be relieved to know that they will not have to worry about a major aspect of their immune system being compromised. While scientists know about the astronauts' skeletal and muscular health during spaceflight and when they return to Earth, much less is known about how spaceflight affects immunity. It has been generally thought, until now, that spaceflight has a detrimental impact on all aspects of the immune system.
Research and development (R & D) into aerospace medicine can be viewed as falling into one of two camps: that aimed at adapting an existing 'terrestrial' medicine for use in the aerospace environment; and that which is newly developed for treating conditions that occur primarily or uniquely in aerospace.
It is now becoming increasingly commonplace to build rockets from parts made from additive manufacturing, but could a different type of 3D printing involving the human body soon be the new normal for keeping astronauts alive on long-duration flights beyond low Earth orbit?
Ever since Boris Popov introduced his “ballistic recovery systems” (BRS) for small airplanes in 1980, skeptics have continued to question their value. Popov came up with the idea of a whole-airplane parachute after surviving the structural failure of his hang glider, and Cirrus Aircraft subsequently incorporated the safety feature in its SR20/SR22 models. On its website, BRS Aerospace claims 380 lives have been saved by the system, which deploys a parachute that gently returns a disabled aircraft to the ground.
Given the growing population of individuals reaching advanced age, it is anticipated that more people with medical conditions will travel by air. This projection underscores the need for healthcare providers and patients to be knowledgeable about adequate preparation for air travel to minimize the risk for adverse events.
An estimated 12% of in-flight emergencies are attributed to respiratory illnesses, and chronic obstructive pulmonary disease (COPD) has been cited as the most common reason for pre-flight medical screening.
Scientists have recently sent tissue chips, a research technology that reflects the human body, into space. On Dec. 4, the first set of NIH-funded tissue chips that model aspects of the human immune system will launch on SpaceX's 16th commercial resupply mission (awarded by NASA) from Cape Canaveral, Florida, to the ISS National Lab.
William "Billy" Cohn, MD, vice president and director of the Johnson & Johnson Center for Device Innovation at TMC , showcased his invention that makes treatment easier for dialysis patients at the 12th annual Pumps & Pipes conference, at a uniquely Houston meeting that assembles leaders from the Bayou's city signature industries: medicine, energy and aerospace.
