Local food production saves costs and carbon

A study by Max Planck Institute for Evolutionary Anthropology found that local food harvesting is more economically-efficient and less carbon-intensive than industrial food production in the Canadian Arctic. Replacing locally-harvested foods with market substitutes would cost over $3 million per year and emit over 1,000 tonnes of CO2-e...

We're not eating Peppa! Preschoolers befriend farm animals

Researchers from SWPS University found that assigning individual characteristics to farm animals can change children's attitudes towards eating meat. In studies involving preschoolers aged 5-6, those who were given a name and unique habits showed increased desire to befriend the animal and decreased willingness to eat its meat.

First of its kind study shines light on LGBTQ+ farmer mental health

A new study reveals that LGBTQ+ farmers are over three times more likely to experience depression and suicidal intent compared to the general population. The research also found that queer farmers face specific challenges, including concerns about identity validation and access to mental health resources.

Tanzania fertilizer use increased after intervention, but changes were not sustained, study shows

A study found that smallholder farmers in Tanzania used more fertilizer and had higher crop yields after an intervention, but the benefits did not last. The researchers attribute the lack of long-term adoption to liquidity constraints and structural factors such as fertilizer availability.

Paternal use of metformin during sperm production not associated with major birth defects

A study of almost 400,000 live births found that paternal use of metformin monotherapy was not significantly associated with major congenital malformations. However, researchers noted that fathers prescribed metformin had higher rates of cardiovascular and metabolic conditions, which could affect reproductive health.

Study suggests ‘biodegradable’ teabags don’t readily deteriorate in the environment and can adversely affect terrestrial species

A new study found that biodegradable teabags made from polylactic acid (PLA) can take years to break down in soil and cause harm to earthworms. The research highlights the need for clear disposal information on product packaging, as many manufacturers are not providing accurate guidance.

Biodiversity in the margins: Merging farmlands affects natural pest control

A new study found that removing hedgerows and field margins decreases the diversity and abundance of arthropods, which can lead to reduced natural pest control. The research suggests that using flowering plants in field margins and implementing agri-environmental measures can be effective ways to increase farmland biodiversity.

Optimal redistribution of nitrogen fertilizer among countries

Shifting excess nitrogen from rich countries to poor ones could increase crop production by 12%, with moderate/food insecure regions seeing significant gains in both fertilizer use and food output. Current levels of production could be maintained with only 53-68% of current nitrogen used through redistribution.

Bitter makes the stomach acidic, but how?

A study by researchers at the Leibniz Institute for Food Systems Biology has uncovered a molecular link between bitter taste receptors and gastric acid release. Bitter substances stimulate parietal cells to secrete protons, leading to acidic stomach conditions. The findings hold promise for innovative treatments of gastric diseases.
