Why play a losing game? Study uncovers why low-income people buy lottery tickets
Although state lotteries, on average, return just 53 cents for every dollar spent on a ticket, people continue to pour money into them — especially low-income people, who spend a greater percentage of their incomes on lottery tickets than the wealthier segments of society. A new Carnegie Mellon University study points to income as an influential factor in the decision to invest in a product that provides poor returns.

“In the study, the researchers note that lotteries set off a vicious cycle that not only exploits low-income individuals’ desires to escape poverty but also directly prevents them from improving upon their financial situations. They recommend that state lottery administrators explore strategies that balance the economic burdens faced by low-income households with the need to maintain important funding streams for state governments.

“‘State lotteries are popular revenue sources that are unlikely to go away anytime soon,’ said George Loewenstein, a study co-author and Herbert A. Simon professor of economics and psychology at Carnegie Mellon. ‘However, it is possible to implement measures that can actually benefit low-income lottery players and lead to fairer outcomes.’ Loewenstein noted that one such potential method for addressing income inequality, which has shown promise in other countries, is tying lottery tickets to savings accounts.”

Sex and lifespan linked in worms
In findings published in Nature, scientists have discovered that smaller, but more structurally diverse chemicals are a significant part of a living thing’s biology. When food is scarce or colonies become crowded, young worms stop developing normally and enter the dauer stage. In this form they can live, without eating or reproducing, for months — about ten times longer than the worm’s normal lifespan. When the dauer finds greener pastures, it finally develops into an adult and resumes its normal aging process.

Licking your wounds: Scientists isolate compound in human saliva that speeds wound healing
A report by scientists from the Netherlands published online in rhe FASEB Journal identifies a compound in human saliva that greatly speeds wound healing. This research may offer hope to people suffering from chronic wounds related to diabetes and other disorders, as well as traumatic injuries and burns. In addition, because the compounds can be mass produced, they have the potential to become as common as antibiotic creams and rubbing alcohol.

‘Nanonet’ circuits closer to making flexible electronics reality
Researchers have overcome a major obstacle in producing transistors from networks of carbon nanotubes, a technology that could make it possible to print circuits on plastic sheets for applications including flexible displays and an electronic skin to cover an entire aircraft to monitor crack formation.
