The ozone layer is coming back. After many decades of depletion, NASA scientists say the protective ozone layer of the atmosphere is recovering and a hole in the ozone over Antarctica is filling in. Phasing out of chlorofluorocarbon chemicals is getting the credit, according to the study in the journal Geophysical Research Letters. The ozone layer absorbs more than 97 percent of the dangerous ultraviolet radiation reaching earth.
Eating a diet high in fresh tomatoes and apples may help slow the natural aging of your lungs, and may even restore some of the lung damage caused by smoking. The study in the European Respiratory Journal shows that lung function is strikingly better in ex-smokers who follow such a diet. However, tomato sauce and processed foods containing fruits and vegetables did not contribute a protective effect. Researchers say the lungs start to decline in most people around age 30.
And finally whether a person is a spendthrift or a tightwad may be set by age five. A study in the Journal of Behavioral Decision-Making shows that children form emotional reactions to spending and saving money between age five and 10, and they translate into the child’s eventual spending behaviors. Researchers say tightwads experience emotional pain connected to spending but spendthrifts don’t have those emotional brakes. Rhose attitudes develop independently of their parents’ spending habits.
