The researchers suggest that improving sleep in the school-age population could lead to improvements in other aspects of health, such as decision making.

Mechanism of longer and deeper sleep after an all-nighter

Research shows that parvalbumin-expressing neurons in the cerebral cortex activate when sleepiness increases, leading to rebound sleep. The activation of CaMKII protein causes rebound sleep by activating these neurons. This study sheds light on the molecular and neural mechanisms of sleep homeostasis.

Coherence entropy unlocks new insights into light-field behavior

Pit-building venom mixers

Researchers found that antlions have a highly effective and complex venom system, producing multiple venom proteins and digestive enzymes to overpower large and defensive prey. Unlike previously thought bacteria-assisted venom production, antlions are free of bacterial symbiotic partners.

Poverty premium on energy costs impacts poorer households

A recent study by the University of Edinburgh found that people in low-income households pay more for their basic energy tariff and incur higher costs per unit of energy compared to more affluent households. The research suggests that factors such as household size, payment method, and property type contribute to these higher premiums.

Lack of purpose and personal growth may precede mild cognitive impairment

A study published in the Journal of Neurology Neurosurgery & Psychiatry suggests that psychological wellbeing noticeably declines 2-6 years before mild cognitive impairment (MCI) diagnosis. Key findings include lower levels of purpose and personal growth among participants with MCI, even without apparent cognitive impairment.
