Gene editing has yielded allergy-free eggs that might prevent severe episodes of anaphylaxis in young children. Ticks and mosquitoes are bringing potentially serious diseases to parts of the US where they are rarely seen. What can we do to stop the spread of malaria and other vectored illnesses? As RFK, Jr. gains popularity in the polls, should scientists debate him? Yes.

* Allergic to eggs? Here’s how tweaking chicken genes can save kids from anaphylactic shock

Utilizing a gene-editing technology called transcription activator-like effector nucleases (TALENs), a team of researchers has cut out the gene in hens that encodes a protein responsible for many eggs allergies in young children. Their study, recently published in Food and Chemical Toxicology, has demonstrated that it's possible to produce low-allergen eggs, but that's only the beginning. The next step is a lengthy review process, including clinical trials, to show that foods containing these eggs are substantially equivalent to the items consumers already have access to in grocery stores and restaurants.

* Ticks and mosquitos are bringing Lyme disease and other vectored illnesses to new places across the US

Warming temperatures, land-use changes and increasing global travel have enabled disease-vectoring ticks and mosquitoes to spread to parts of the world in which they're rarely seen, including regions of the US with more temperate climates. Most of these illnesses remain uncommon. For example, the CDC reports that the US has experienced roughly 150 locally acquired cases of malaria and 60 limited outbreaks over the last five decades, and 2,000 cases found in returning international travelers. Nevertheless, slight increases raise an important question: how do we prevent malaria and other nasty diseases from regaining a foothold in the United States?
