Researchers have reviewed genetic circuits that use light, ultrasound or magnetic fields to control gene activity and cell functions. The analysis compares how these systems sense outside signals, process them inside cells and produce genetic responses, while outlining the tests needed for potential medical use.
Researchers developed a portable, one-tube test for African swine fever virus that uses a smartphone-connected analyzer to read fluorescence. The assay detected a viral DNA standard at low concentrations and correctly classified simulated positive and negative serum samples.
A study of 1,218 consumers in Spain, Germany and the United Kingdom found that conventional pesticides were generally seen as riskier than gene-edited watermelons. Consumers also preferred zero-residue pesticides to organic-certified alternatives, although 22% to 27% rejected gene-edited watermelons.
