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.
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. Researchers say this letter shows Galileo attempted to moderate his tone in writing to church authorities.
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.
Mini-gastric bypass surgery is just as effective long-term as Roux-en-Y bypass surgery for treating morbid obesity and gastroesophageal reflux disease, according to a study in Bariatric Surgical Practice and Patient Care. GERD symptoms may be exaggerated in the short term in patients who undergo mini-gastric procedures but significantly decrease by one year, researchers said.
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.
Scientists, engineers and students will discuss opportunities, challenges and ethical considerations of using big data in research during symposia at Sigma Xi, The Scientific Research Honor Society's Annual Meeting and Student Research Conference. The events will take place Oct. 26-28 at the Hyatt Regency San Francisco Airport in California. The Student Research Conference on Oct. 27 includes a research poster competition that is open to high school students through graduate students. Register today!
American Scientist's special issue on big data and astrophysics is now available
The September-October issue of American Scientist illuminates the ways that astronomers employ computational techniques to manage the ever-increasing flood of data from state-of-the-art observatories -- and how these techniques can benefit other areas of science. Sigma Xi members should look for their digital or print editions (additional content is exclusively available on the americanscientist.org website). Nonmembers can find the magazine on newsstands or order a copy for $5.95 plus shipping fees by calling 1-800-282-0444 and selecting option 4.
