Welcome to this week’s science newsletter, featuring articles written by researchers and scientists. Here are highlights from the past week.
Interest is growing in using CRISPR to engineer viruses that combat antibiotic-resistant bacteria. Arizona State biologist Kevin Doxzen, who worked in the lab of CRISPR co-discoverer Jennifer Douda, writes about new strategies using viruses to kill harmful bacteria that traditional treatments struggle to defeat. He explains how this technique, known as phage therapy, has been given a powerful new tool in CRISPR, which allows
virus designers to precisely target bacterial DNA.
Technology ethicists say AI is making us less human. Artificial intelligence is slowly sucking the serendipity out of daily life, write Nir Eisikovits and Dan Feldman at UMass Boston’s Applied Ethics Center. Algorithms are trained on past behaviors and patterns, which leads to more predictable outcomes in things ranging from movie recommendations on Netflix to, more ominously, bias in corporate decisions, such as who gets a bank loan. Their biggest worry? People’s ability to make choices is getting worse, particularly moral decisions.
The risk of heavy metals in baby foods is real. University of Connecticut health researcher C. Michael White unpacks a recent congressional report that found arsenic, lead and other heavy metals are present in baby foods. The causes are ultimately our soil and the pollutants that go into it via sources like fertilizer or pollution from burning coal. He walks through the guidance on safety levels and recommends alternatives
to rice-based products and plants that have close contact with the soil, such as carrots and sweet potatoes.
