...Another dark cloud for the GOP is the plan's so-called "doughnut hole." Under the standard benefit, seniors will get 75% of their drug costs covered by Medicare until their total drug spending reaches $2,250. Beneficiaries then pay all drug costs until their bills reach $5,100. That $2,850 gap in coverage has been nicknamed the "doughnut hole" when seniors must pay for drugs with their own money-as well as continuing to have to pay their average monthly premium of $32-and Democratic political strategists calculate that most seniors will bear the brunt of it around...
Hardy and plentiful as they seem, frogs are actually very frail things, with a semipermeable skin that leaves them vulnerable to even the slightest hiccup in their environment. So when entire species of brightly colored harlequin frogs started dying off in the cloud forests of Central and South America about 25 years ago, scientists suspected that something in the amphibians' ecosystems--they weren't sure what--had gone awry...
...have shown that it's not heat alone that kills harlequins but also a pathogen--the chytrid fungus--that attacks their skin. The chytrid is actually a cool-weather organism, doing best at temperatures from 63°F to 77°F. Paradoxically, an effect of global warming is to increase cloud cover in the tropical forests, lowering daytime temperatures and making the frogs more vulnerable to fungal assault...
...most persuasive piece of evidence in the new study, led by J. Alan Pounds of the Monteverde Cloud Forest Preserve in Costa Rica and published in Nature, is a graph that shows both annual changes in average temperature and the number of frog extinctions per year on the same grid: the jagged lines track each other with eerie precision. Species die-offs follow warm years 80% of the time. With tropical air temperatures from 1975 to 2000 rising three times as fast as the 20th century average, things should only get worse...
...miles (10,000 km) of Pluto?40 times as close as the Earth is to our own moon ? KUIPER BELT Voyage into Kuiper Belt 2016-2020 What is the Kuiper Belt? Named for Gerard Kuiper, who predicted its existence in the 1950s, it is a vast, disk-shaped cloud of thousands of icy bodies that starts near Neptune and reaches to about 4.5 billion miles (7.5 billion km)from...
