Feed management decisions are crucial in mitigating greenhouse gas (GHG) and nitrogen (N) emissions from ruminant farming systems. However, assessing the downstream impact of diet on emissions in dairy production systems is complex, due to the multifunctional relationships between a variety of distinct but interconnected sources such as animals, housing, manure storage, and soil. Therefore, there is a need for an integral assessment of the direct and indirect GHG and N emissions that considers the underlying processes of carbon (C), N and their drivers within the system.

- Orthostatic dysregulation can happen when people return to normal gravity after being in microgravity, which is common in space travel; external peripheral skin cooling (PSC) has been proposed as a potential solution to this issue.
- A study called "Coolspin" was conducted with 18 healthy male volunteers, testing PSC while subjected to increased gravitational forces (up to +4g) in a centrifuge, measuring various cardiovascular parameters.
- The results showed that PSC did not significantly improve cardiovascular stability or hemodynamic activity during +Gz, suggesting that the cooling method used may not have been adequate or the subjects' responses to cooling were low, indicating a need for further research.
On 26 September 2022, the Double Asteroid Redirection Test (DART) spacecraft struck Dimorphos, a satellite of the asteroid 65803 Didymos. Because it is a binary system, it is possible to determine how much the orbit of the satellite changed, as part of a test of what is necessary to deflect an asteroid that might threaten Earth with an impact. In nominal cases, pre-impact predictions of the orbital period reduction ranged from roughly 8.
