Health Research: New sensor detects spoiled meat ♦ Heavy snoring, sleep apnea may signal earlier memory decline ♦ BPA can disrupt sexual function

New sensor detects spoiled meat Chemists have devised an inexpensive, portable sensor that can detect gases emitted by rotting meat, allowing consumers to determine whether the meat in their grocery store or refrigerator is safe to eat.
Unnecessary preoperative testing still done on cataract patients Although routine preoperative testing is not indicated for patients undergoing cataract surgery, researchers have found that it is still a common occurrence and is driven primarily by provider practice patterns rather than patient characteristics.
Heavy snoring, sleep apnea may signal earlier memory and thinking decline Heavy snoring and sleep apnea may be linked to memory and thinking decline at an earlier age, according to a new study. The research also suggests that treating the disorders with a breathing machine may delay the decline.
BPA can disrupt sexual function in turtles, could be a warning for environmental health Bisphenol A (BPA) is a chemical used in food storage products and resins that line plastic beverage containers. Often, aquatic environments become reservoirs for BPA, and turtle habitats are affected. Now, a collaboration of researchers has determined that BPA can alter a turtle's sexual differentiation. Scientists are concerned findings could indicate harmful effects on environmental and human health.
Advancements in retinal detachment research pave the road to better visual recovery Age, disease and even playing certain sports like basketball can increase a person’s risk of developing a detached retina. While surgery is typically used to treat the condition, subsequent scarring and damage to the retina can cause permanent vision problems or even blindness. New research is exploring the biochemical processes that lead to retinal scarring in the hopes of developing the first ever drug intervention to help improve the way retinas heal.
