Experimental Physiology, EarlyView.Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Photometric Observations and Analysis of Active Asteroid (62412) 2000 SY178
The Astronomical JournalThe active asteroid (62412) 2000 SY178 is a C-type object located in the outer main belt and was first reported to exhibit a dust tail in 2014 May. Before and after its recent perihelion, we carried out long-term observations of 2000 SY178 with the ...

A primordial noble gas component discovered in the Ryugu asteroid and its implications
Nature CommunicationsRyugu is the C-type asteroid from which material was brought to Earth by the Hayabusa2 mission. A number of individual grains and fine-grained samples analysed so far for noble gases have indicated that solar wind and planetary (known as P1) noble gases ...

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds
Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Experimental Observation of a Calcium Silicon Double Carbonate
Angewandte Chemie, Volume 138, Issue 9, 23 February 2026.High‐pressure and ‐temperature reactions between Ca5(Si2O7)(CO3)2 tilleyite and CO2 carbon dioxide yield the first experimental evidence of the double carbonate Ca2Si(CO3)4 and a new Ca2(C4O10) phase containing tetrahedral [CO4] units. These findings reveal unexpected carbonate chemistry and highlight pathways for carbon incorporation under mantle ...
