Researchers have developed a gene drive that causes female Anopheles gambiae mosquitoes to stop laying eggs by targeting the doublesex gene, potentially leading to population collapse. Success of the gene drive in the wild could help stem the spread of malaria, scientists say.
About 200 students at three high schools in Alabama and Mississippi will learn welding and machinery skills to help them prepare for jobs at a military shipbuilding company in the area. New labs, designed by the shipbuilder, were installed at the schools.
The original version of the letter written by Galileo Galilei in 1613 that he later asked to be sent to the Catholic Church has been found in the Royal Society library, according to findings to be published in the journal Notes and Records.

Rising global temperatures may affect the pork industry by reducing protein levels in meat. "Regardless of which data set we looked at, there was about a 10% decrease in overall productivity [pork yield] caused by heat stress every year," said Chris Hostetler of the National Pork Board.
Earth's wobble as it spins on its axis is caused by glacial ice melt and sea level rise due to climate change, the upward expansion of land masses as glaciers retreat, and the mantle's slow-motion churn, according to findings published in Earth and Planetary Science Letters. "The amount [of drift] is not a huge amount," said lead researcher Surendra Adhikari.
The flower Orychophragmus violaceus contains seed oils that have potential as a renewable lubricant because of their unique fatty acid content, according to Chinese and US researchers at Huazhong Agricultural University and Indiana University -- Purdue University Indianapolis. "Commercially, it may prove to be a really good bio-renewable component in lubricants," said IUPUI bio-organic chemist Robert Minto.
The NIH has awarded a $9.4 million grant to establish a center at The Miriam Hospital in Providence, R.I., that will focus on ways to treat drug-resistant bacteria. The collaboration also involves Rhode Island Hospital and Brown University.
Wright State University in Ohio has received a $1.8 million grant from the National Institute of Allergy and Infectious Diseases to study viral respiratory infections. The focus of the study will be viral receptors present in human cells.
An Ohio school district is offering career academies and other programs designed to help students land jobs after high school. The district offers academies in advanced technology and engineering, among others, plus programs to help students earn an associate degree while still in high school.
