Is it feasible to resume high salinity wastewater as a plant nutrient medium for plant hydroponics in CELSS?

Two crops, celery and cordifolium, were cultivated using reused medium from domestic wastewater and standard Hoagland nutrient solution. The results showed that the reused medium was effective in promoting plant growth, with cordifolium exhibiting better performance than celery, despite initial salt toxicity issues.

Forest wildflowers and their overstory trees are changing with climate, but not always keeping pace

Research found that North American wildflower timing is more sensitive to warmer temperatures than surrounding tree growth, threatening the flower's ability to grow. In contrast, European and Asian forests show a synchronized shift in tree and wildflower phenology, potentially leading to increased light for wildflowers.

Bats protect young trees from insect damage, with three times fewer bugs

A new study found that bats play a crucial role in protecting young tree seedlings from insect damage, with three times fewer bugs and five times more defoliation when bats are absent. The research reveals a mutually beneficial relationship between bats and oak trees, with bats serving as a key predator for insects that harm the trees.

We need to stop thinking of insects as ‘creepy crawlies’ and recognise their keystone role in ecosystems, say scientists

A new paper highlights the crucial role insects play in ecosystems, including pollination, food sources, and mental health benefits. The authors advocate for a shift in public perception of insects, citing government inaction on biodiversity policy, and outline strategic priorities to support insect conservation.

How do mushrooms become magic?

Scientists are conducting a first-of-its-kind study to investigate the origin of psychedelic compounds in fungi, including psilocybin found in 'magic mushrooms'. The research aims to understand the evolution of these compounds and their potential applications in medicine and conservation.

What goes on in the brain when it gets too hot?

Researchers at NTNU studied zebrafish brain activity while increasing temperature, finding that brains completely stopped responding to stimuli but then 'lit up' when temperatures reached extreme levels. Adding oxygen improved thermal tolerance and recovery rate in fish, suggesting a key role for glial cells in regulating oxygen supply.

Safe havens for cooperation

A research team used game theory to analyze cooperation in networks and found that networks with a high level of cooperation can emerge if individuals take a clear-cut position against free riders. The study also showed that if contributors leave an environment too quickly, it leads to a lower level of cooperation.
