Brazil's frogs are rebounding, and a $40 HIV shot heads overseas

A team from the Smithsonian's National Zoo and Conservation Biology Institute and Penn State went back to frogs preserved in museum collections decades earlier. They report in Molecular Ecology that the chytrid fungus, Batrachochytrium dendrobatidis, was moving through the region at the same time as the disappearances 6. "After almost 50 years, we still aren't confident what caused many historical amphibian die-offs, making these declines some of the most enduring cold cases in wildlife epidemiology," said lead researcher Jack Boyette 6.

Gilead signed licensing deals two years ago with six generic makers to supply 120 mostly low- and middle-income countries, and Dr. Reddy's plans to start shipping next month 7779. The annual cost per person will be $40, which STAT's report compares to the price of daily tablets 77.

One light behaved as expected, with diminishing returns as it got brighter. Two opposing lights of different strength made the plant lean toward the brighter one, but not in proportion to the difference 233. Then came the odd trial: two opposing lights of identical intensity plus a weaker third light off to the side. The sunflower bent toward the weak one 233.

They perked up before their fevers peaked, so the fever itself was not what made them sluggish 234. The injection lit up the body-monitoring network, including the brainstem, hypothalamus and insular cortex. When the researchers recorded hundreds of neurons at once, the insular cortex predicted sickness better than the primary somatosensory cortex did 234. The work appears in Current Biology.

Beavers were last recorded around the loch in 1526 and 1527 192. More than 73% of respondents to the consultation expressed support afterward 192. The animals will typically come from other spots in Scotland where they are damaging prime farmland or are not settling well 192.

Some furnaces were nearly an adult's arm span wide, with thick walls built to hold more than 2,100 degrees Fahrenheit 1. They were designed to pull air in and out through a chimney, so no one had to work bellows 1. Archaeometallurgist Ezekiel Mtetwa says the number and size of the furnaces and the natural-draft design "indicate intensive and technologically sophisticated iron production" 1.

Holocaust Memorial Museum 217. After a 1941 agreement let many leave, some children made the long journey through Iran to India 217. There, Maharaja Digvijaysinhji Ranjitsinhji Jadeja of Nawanagar welcomed nearly 1,000 children aged 2 to 15 to Balachadi from 1942 to 1946 217. The camp had barracks, a school, a library, a Catholic church, kitchens and play areas, and Polish teachers kept lessons going in Polish 217. He told arrivals, "Do not consider yourself orphans any more. You are now Nawanagaris, and I am Bapu" 217. He also insisted the Polish flag be raised daily and the anthem sung, though Poland was not free 217.
