Lab mosquito population vanishes due to gene drive
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.

Long-lost version of Galileo letter is found
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.

Global warming having effect on pork production, researchers say
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.

Researchers find 3 reasons for Earth's wobble
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.

Scientists: Orchid's oil seeds yield unique fatty acids
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.

GERD symptoms improve with both Roux-en-Y, mini-gastric bypass
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.

Tests are a gift. And great tests are a great gift. To fail the test is a misfortune. But to refuse the test is to refuse the gift, and something worse, more irrevocable, than misfortune.
