Solar energy is becoming more and more popular as prices drop, yet a home powered by the Sun isn’t free from the grid because solar panels don’t store energy for later. Now, researchers have refined a device that can both harvest and store solar energy, and they hope it will one day bring electricity to rural and underdeveloped areas.

The problem of energy storage has led to many creative solutions, like giant batteries. For a paper published today in the journal Chem, scientists trying to improve the solar cells themselves developed an integrated battery that works in three different ways.

CLICK HERE - STUDY - PNAS - Seroprevalence, risk factor, and spatial analyses of Zika virus infection after the 2016 epidemic in Managua, Nicaragua

sph.berkeley.edu - August 30, 2018

Almost half of the population of Managua, Nicaragua, is infected with Zika virus, according to a study by UC Berkeley School of Public Health researchers. Eva Harris, professor of Infectious Diseases and Vaccinology at the School of Public Health and director of the UC Berkeley Center for Global Public Health, led the research, which was published August 27 in the Proceedings of the National Academy of Sciences.

“Knowing that 50 percent of the population was infected in only a three-month period during the epidemic is important because it means that another epidemic of that size and ferocity in the near future is very unlikely,” says Harris.

News of Antarctica's accelerating ice melt garnered worldwide headlines yesterday, as scientists revealed that 3 trillion tons of ice has been lost to the sea since 1992 — mostly from the thawing West Antarctic Ice Sheet and Antarctic Peninsula.

Why it matters: The location of the ice melt is important for determining the future of coastal communities, according to climate scientists. And, due to West Antarctica melting, it turns out that the U.S. coastline will be hit extra hard . . .

A new study shows that storms are staying in one place longer, much like Hurricane Harvey did last year.

 . . . A study published Wednesday in the journal Nature focuses on what is known as translation speed, which measures how quickly a storm is moving over an area, say, from Miami to the Florida Panhandle. Between 1949 and 2016, tropical cyclone translation speeds declined 10 percent worldwide, the study says. The storms, in effect, are sticking around places for a longer period of time.
