Why One Family With Measles Is Reconsidering Their Anti-Vax Position

People on social media pilloried them as the “measles family” after they became infected with the virus during their Disneyland vacation and brought the disease back to their hometown of Kearny, Arizona.

Now, after exposing an estimated 1,000 people to the virus, Jannae Yslas-Roach, a 32-year-old mother of four, explained her family’s side of the story in an in-depth interview with The Arizona Republic about the family’s ordeal.

Yslas-Roach told The Arizona Republic that the variation and ambiguousness of their measles symptoms, as well as doctors’ unfamiliarity or lack of urgency when faced with potential measles cases, resulted in delays in diagnosing. This left the family more opportunities to expose others to the disease over several weeks in January. In all, because family members made multiple trips to different health centers or ran errands, the group is thought to have exposed about 1,000 people in Arizona to the virus, including those too young or immunocompromised to get the vaccine.

“I never in a million years thought this would go as far as it has,” Yslas-Roach said to the Arizona newspaper. “I’m a believer that if you do not vaccinate your children, you have a responsibility to keep your kids out —> Read More Here

Sangay Volcano Erupts in Ecuador

This past December, our team trekked up a remote, active volcano in Ecuador known as Sangay, “The Giver.” We collected more than 60 geologic samples from lava flows and rocks all up and down the slopes, which will help us better understand the working of this and other volcanoes around the world.

One month after we departed, Sangay started erupting with ferocity again. This renewed activity, first detected by airline pilots, was captured in photographs from the Macas, Ecuador region and has been imaged by satellite, all seen below.

According to MIROVA (Middle InfarRed Observation of Volcanic Activity), which looks at MODIS (Moderate Resolution Imaging Spectroradiometer) data aboard the Terra EOM and Agua EOS satellites, since January 15, 2015, there has been detectable thermal activity at the summit of Sangay, with a multitude of thermal alerts with significant radiant heat emitting from its summit region (spanning from 1 to 10 MW). Significantly, at 03:20 (UTC) on Jan 26, 2015, a thermal anomaly of 75 —> Read More Here

Caging of molecules allows investigation of equilibrium thermodynamics

High performance materials for gas storage, thermal insulators or nanomachines need a thorough understanding of the behavior of the material down to the molecular level. Thermodynamics, which have been developed two hundred years ago to increase the efficiency of steam engines, typically observes and averages over a large number of molecules. Now a team of scientists has developed a methodology, to investigate the equilibrium thermodynamics of single molecules. —> Read More Here
