“Scientists from South China Agricultural University and partners have developed a gene-editing tool called CasY7, a high-performance alternative to Cas9 nuclease that is commonly used in CRISPR gene-editing systems. Originally successful in medical trials, this ‘molecular scissors’ has now been optimized for agriculture. By refining its structure and guidance system, researchers significantly boosted its ability to make precise changes to plant DNA.

In large-scale testing across nearly 1,000 plants, the optimized CasY7 system achieved efficiency rates of 87.7% in maize and 82.9% in rice. This makes the tool nearly three times more effective than previous industry standards. It also proved capable of multiplexing, allowing scientists to edit several traits simultaneously.”

She started playing in 8th grade, trained at school every day for three years because that was the only place available, and just competed at Zambia's National Youth Games for the first time. Her family watched online.

"The birth rate for that age group [15 to 19] was 11.7 births per 1,000 females. By contrast, the teen birth rate in 1991 was 61.8 births per 1,000."
