Landscape and sustainability of organic farming

A global meta-analysis of organic farming systems reveals a significant increase in biodiversity and profitability relative to conventional agriculture. The study found that larger field sizes around organic sites are associated with higher biodiversity, but lower crop yields and profit margins compared to conventional sites.

Doctors and immunologists implement a new approach for melanoma treatment

Isolated limb infusion (ILI) is a new method for treating melanoma metastases confined to an extremity, offering a more targeted and less exhausting alternative to systemic chemotherapy. The study found an overall response rate of 76% and long-term limb salvage rate of 90%, comparable to high-volume centers in the US and Australia.

People with obesity who experience self-directed weight shaming benefit from intervention

A new study found that people with obesity who receive a stigma-reduction intervention, combined with standard behavioral weight loss treatment, devalue themselves less due to their weight. The Weight Bias Internalization and Stigma (BIAS) program helped participants combat negative thoughts and increase self-acceptance.

Opioid dependence found to permanently change brains of rats

Researchers found that opioid dependence leads to permanent neuro-adaptations in the central nucleus of the amygdala, affecting pain transmission and GABA receptor activation. Normalizing nociceptin levels resulted in reduced opioid consumption, suggesting the peptide as a promising target for opioid use disorder treatment.

Study shows effects of Chinese divorce law on women's wellbeing

A new study by Yale sociologist Emma Zang found that China's 2011 judicial interpretation on property rights during divorce initially harmed women's wellbeing, but couples adapted over time to share property equally. Despite adaptations, the change has lingering costs, including increased housework for women and loss of property rights.

NIH study finds benefits of fetal surgery for spina bifida persist through school age

Children who underwent fetal surgery for spina bifida at a young age are more likely to walk independently and require fewer follow-up surgeries compared to those who had traditional corrective surgery after birth. The study found that these children also scored higher on motor skills and had lower rates of hydrocephalus.

New research shows more people knowingly use fentanyl

A study by BC Centre for Disease Control and University of British Columbia found that two-thirds of people who use drugs are aware they've taken fentanyl. The study emphasizes the importance of harm reduction services, substance treatment, and pharmaceutical alternatives to reduce devastating impacts of fentanyl on communities.

Deciphering the sugar code

Scientists at the University of Münster have developed a vaccine-like treatment that stimulates plants' natural immune system using a specific pattern in chitosan, a biopolymer. This breakthrough could lead to reduced chemical pesticide use and improved plant growth, as well as potential applications in scar-free wound healing.

Discovery sheds new light on how cells move

Researchers have discovered that the force each cell applies to the surface beneath it primarily controls its shape and motion in a collective cell migration. This finding provides new insights into how cells rearrange and migrate as a group, which could lead to the development of new treatments to speed up wound healing.

The 'place' of emotions

A study by IMT School for Advanced Studies Lucca found that a specific region of the right temporo-parietal junction can represent various affective states. The researchers used fMRI data and found smooth transitions in this region, which allows the brain to map emotions in a single patch of cortex.

Shaping the social networks of neurons

A protein complex of Teneurin, Latrophilin, and FLRT attracts neighboring neurons during development, enabling synapse formation and information exchange. In early brain development, however, the same proteins repel migrating nerve cells, guiding them to their target brain area.

Lung microbiome may help predict outcomes in critically ill patients

Research suggests that lung bacteria can predict clinical outcomes in critically ill patients, with certain bacteria associated with worse outcomes and the presence of gut-associated bacteria found in the lungs. The study's findings have implications for developing new therapies to prevent and treat critical illness.
