Artificial intelligence and farmer knowledge boost smallholder maize yields

A four-year study in Colombia's maize-growing region shows that combining farmers' knowledge with data on weather and soils can increase yields substantially. Machine learning algorithms helped develop site-specific guidelines for crop management, reducing fertilizer costs and stabilizing yields.

Mindfulness may reduce opioid cravings, study finds

A study published in Drug and Alcohol Dependence found that combining mindfulness techniques with methadone therapy reduces opioid cravings and improves pain management. Researchers at Rutgers University discovered that mindfulness-based interventions can increase self-awareness, self-control over cravings, and emotional regulation.

Targeting deeply held values crucial for inspiring pro-environmental behavior

A recent study suggests that targeting deeply held values is crucial for inspiring pro-environmental behavior. Researchers found that people with egalitarian values tend to care more about benefiting the environment, while those with hierarchical values prioritize authority and influence. The study's conclusions highlight the importanc...

Gene mutation in the chloride channel triggers rare high blood pressure syndrome

Researchers have discovered that a gene mutation in the chloride channel causes hyperaldosteronism, leading to abnormally high blood pressure and kidney damage. The study used a mouse model to investigate the pathological mechanisms of the disease, providing insights into the effects of an open chloride channel on aldosterone production.

Lost in combat?

Researchers uncovered a collection of 31 unusual objects, believed to be the personal belongings of a Bronze Age warrior who died on the battlefield 3,300 years ago. The discovery provides insights into the equipment and origins of the warriors, with evidence suggesting at least some were from southern Central Europe.

Empty spaces, how do they make a protein unstable?

Researchers used NMR spectroscopy and hydrostatic pressure to study the impact of internal cavities on protein stability. They found that filling these cavities with water destabilizes the protein, which has significant implications for industrial enzymes and biological drugs.

Shipment tracking for 'fat parcels' in the body

Scientists develop a new method to track lipid metabolism in the body, allowing for clearer distinction between marked and unmarked lipids. This breakthrough enables researchers to examine both normal and pathological deviations in detail, with potential applications for investigating drug side effects on fat metabolism.

The nano-guitar string that plays itself

Researchers at Lancaster University created a nano-electronic circuit that vibrates on its own when given an electrical current, generating motion directly from the energy. The carbon nanotube wire used in the device oscillated at frequencies too high for human hearing, producing sound waves equivalent to an A string pitched 21 octaves...
