Gene editing could eliminate mosquitoes, but is it a good idea? (CNN)

Researchers used a gene editing tool, CRISPR, to wipe out a population of malaria-carrying mosquitoes in the lab. Questions remain about how releasing this technology into the wild would impact the environment.

Many Common Sunscreens May Harm Coral. Here's What To Use Instead (NPR)

Hawaii’s governor David Ige is expected to sign the world’s first ban on the sale of sunscreens containing the chemicals oxybenzone and octinoxate this week. The state is banning the products because of concerns they may be harming one of the state’s biggest attractions — coral reefs. While it doesn’t kick in until 2021, the move is already prompting a public health pushback.

As lab-grown meat advances, U.S. lawmakers call for regulation (Science)

Lab-grown chicken, beef, and duck products are edging toward the U.S. market—despite enduring confusion about how they’ll be regulated. But language buried in a draft spending bill released by a U.S. House of Representatives appropriations panel this week suggests some lawmakers are eager to get rules in place. A one-sentence proposal in the bill would put the U.S. Department of Agriculture (USDA) in charge of regulating products made from the cells of livestock or poultry, and instructs the agency to issue rules about how it will oversee their manufacture and labeling.

Salmon spawn fierce debate over protecting endangered species, thanks to a single gene (Science)

They concluded that the genetic change that produced spring-run Chinook occurred only once in the species’s history. And new data published on 29 April on bioRxiv show that in rivers where spring runs disappeared decades ago, less than 1% of the remaining fish carry a copy of the early migration version of the gene. The scarcity of that gene makes it very unlikely a spring run will reappear once lost.

Global climate science group ponders effort to recruit more female authors (Science)

The world’s leading climate science body is expected to decide this week on whether to establish a new task force on promoting gender equity within the male-dominated group. The move comes on the heels of a study finding that although the Intergovernmental Panel on Climate Change (IPCC) has increased the proportion of women involved in writing its authoritative reports, barriers to participation remain.

Uganda removes key hurdle to GM crops (Science)

Biotech researchers here are celebrating the long-awaited passage of a bill this week that clears the way for large-scale field tests and commercial release of genetically modified (GM) crops. Uganda, with several engineered varieties waiting in the wings, is expected to join a handful of other African nations moving quickly to bring homegrown GM foods to the market.

Should Physicians Consider the Environmental Effects of Prescribing Antibiotics? (AMA Journal of Ethics)

Pharmaceuticals are beginning to receive attention as a source of pollution in aquatic environments. Yet the impact of physician prescription patterns on water resources is not often discussed in clinical decision making. Here, we comment on a case in which empiric antibiotic treatment might benefit a patient while simultaneously being detrimental to the aquatic environment. We first highlight the potential harm caused by this prescription from its production to its disposal.

CRISPR reveals genetic master switches behind butterfly wing patterns (Nature)

The brilliant, intricate patterns on butterfly wings — from haunting eye spots to iridescent splashes of blue — look as if they were painted on by teams of artists. Researchers thought that a complex collection of genes might be responsible, interacting to build up the final pattern. But two studies now suggest that two genes play an outsize role in determining the wing’s lines and colours. Turning off these ‘master’ genes disrupts the canvas, dulling the colours or turning the insects monochromatic.
