Tokyo, Japan – Scientists from Tokyo Metropolitan University have revealed key parts of the biochemical pathways connecting stress to sexual dysfunction. By studying Drosophila fruit flies, they showed that the neurotransmitter dopamine was responsible for determining how long male flies showed persistent courtship suppression after being confined in a small space, but not whether mating was suppressed in the first place. Their findings in a key model organism illuminate neurobiological factors causing sexual dysfunction in other organisms, including humans.

In an environment of radiation, extreme temperatures and razor-sharp dust, researchers are designing how humans will build, and ultimately survive, on the moon.

JMIR Publications released a News and Perspectives expert analysis on consumer wearable platforms’ forays into the clinical health care space.

Data beamed back from Mars by the NASA spacecraft MAVEN provides the first evidence that a phenomenon protecting planets from solar winds can occur in the atmospheres of worlds that lack strong magnetic fields, according to research led by West Virginia University planetary scientist Christopher Fowler.

The cradles of baby stars have a wheel-and-spoke like shape, with streams of gas converging toward a dense central hub. Using 3D simulations, researchers from Kyushu University and Nagoya University found that when an external shockwave strikes a gas cloud with a pinched magnetic field, it reorganizes the cloud into radial filaments. These findings open a new window into the environments where massive stars and star clusters are born.

The Sun's internal 'biorhythm' – which plays a critical role in the space weather we experience on Earth – has mysteriously changed over the past 40 years, a new study suggests.

Listening to tiny sound waves inside our star's 'heart' led researchers to discover that it may be entering "a different mode of behaviour". They now need to explore what this means.

The research, published today in Monthly Notices of the Royal Astronomical Society, is of particular significance to space weather.

University of Warwick astronomers have found a new way to estimate the masses of planets hidden inside the dusty disks surrounding young stars.

Tiny sound waves inside the Sun unmask evidence of systematic changes in the solar activity cycle over the last 40 years – with implications for predicting space weather.
