Most children told of biological origins

New research finds that 86% of parents in New Zealand disclose their child's donor conception to them by age 18, with most sharing the information before age 10. Heterosexual couples are less likely to share this info, but same-sex couples and single women have higher disclosure rates.

An old drug, in a low dose, shown to be safe and effective in preventing progression of type 1 diabetes in children and young people (MELD-ATG trial)

A new trial has shown that a lower dose of the immunomodulatory drug ATG is safe and effective in preventing the progression of type 1 diabetes in young people. The study found that the drug was able to arrest or delay the progression of T1D at a dose as low as 0.5mg/kg, with a good safety profile.

Recent advances in stabilization strategies for zinc anodes in aqueous zinc-ion batteries

Researchers developed four stabilization strategies to improve zinc anode stability in AZIBs, including artificial SEI layers, electrolyte modification, bioinspired designs, and structural optimization. These approaches enhance cycle life, Coulombic efficiency, and overall performance of AZIBs.

El Niño spurs extreme daily rain events despite drier monsoons in India

A new study finds that El Niño increases the likelihood of extreme daily downpours in India's wetter regions, potentially leading to hazardous conditions. The research suggests changes in atmospheric buoyancy and low-pressure system tracks drive this intensification, which has remained steady over time despite regional shifts.

Consistent policy, not “patchwork” regulations, recommended for the coexistence of crops

A new review from the University of Adelaide highlights inconsistencies in Australian crop regulations, affecting the coexistence of genetically modified (GM) and non-GM crops. The current regulatory framework is inadequate, leading to varying standards across different sectors, making it difficult for farmers to ensure compliance.

Tirzepatide improves blood sugar control in children aged 10-17 years with type 2 diabetes inadequately controlled on existing therapies (SURPASS-PEDS trial)

The SURPASS-PEDS trial shows that tirzepatide significantly improves HbA1c levels, BMI, and fasting glucose in children aged 10-17 years with type 2 diabetes. The study demonstrates sustained improvements over a year-long period, making it a potential safe and efficacious treatment option for youth-onset type 2 diabetes.

Small nuclear RNA base editing a safer alternative to CRISPR, UC San Diego researchers find

Researchers at UC San Diego have created a new genetic editing approach that uses small nuclear RNA base editing, which can modify the genetic code with greater precision and safety than CRISPR. This method has the potential to treat various diseases, including neurodegenerative, cardiovascular, and immune disorders.
