Mapping Volcanic Heat on Io

Science

A new study finds that the pattern of heat coming from volcanoes on Io’s surface disposes of the generally-accepted model of internal heating. The heat pouring out of Io’s hundreds of erupting volcanoes indicates a complex, multi-layer source. These results come from data collected by NASA spacecraft and ground-based telescopes and appear in the June issue of the journal Icarus.

A map of hot spots, classified by the amount of heat being emitted, shows the global distribution and wide range of volcanic activity on Io. Most of Io’s eruptions dwarf their contemporaries on Earth. (more…)

More Seniors Being Held for Observation

General, Health

A new study finds that more elderly patients in the emergency departments of hospitals are being held for observation rather than admitted as inpatients. Pressure from Medicare to reduce unnecessary hospitalization may be driving the trend. But being classified as an outpatient, rather than being admitted, can increase out-of-pocket costs for patients. The study is reported in the June edition of Health Affairs.

PROVIDENCE, R.I. [Brown University] — Nobody wins when patients stay in the hospital unnecessarily, so the federal government in recent years has pushed hospitals to be careful about admitting Medicare recipients as inpatients. The apparent result is that more patients are being “held for observation” instead, according to a new study by Brown University gerontologists. While the shift in how hospitals care for elderly patients in the emergency department may reduce costs to Medicare, it can also increase out-of-pocket expenditures for patients. (more…)

NASA’s Spitzer Finds First Objects Burned Furiously

Science

PASADENA, Calif. — The faint, lumpy glow given off by the very first objects in the universe may have been detected with the best precision yet, using NASA’s Spitzer Space Telescope. These faint objects might be wildly massive stars or voracious black holes. They are too far away to be seen individually, but Spitzer has captured new, convincing evidence of what appears to be the collective pattern of their infrared light.

The observations help confirm the first objects were numerous in quantity and furiously burned cosmic fuel.

“These objects would have been tremendously bright,” said Alexander “Sasha” Kashlinsky of NASA’s Goddard Space Flight Center in Greenbelt, Md., lead author of a new paper appearing in The Astrophysical Journal. “We can’t yet directly rule out mysterious sources for this light that could be coming from our nearby universe, but it is now becoming increasingly likely that we are catching a glimpse of an ancient epoch. Spitzer is laying down a roadmap for NASA’s upcoming James Webb Telescope, which will tell us exactly what and where these first objects were.” (more…)

Building Molecular ‘Cages’ to Fight Disease

UCLA-created nanoscale protein containers could aid drug, vaccine delivery

UCLA biochemists have designed specialized proteins that assemble themselves to form tiny molecular cages hundreds of times smaller than a single cell. The creation of these miniature structures may be the first step toward developing new methods of drug delivery or even designing artificial vaccines.

“This is the first decisive demonstration of an approach that can be used to combine protein molecules together to create a whole array of nanoscale materials,” said Todd Yeates, a UCLA professor of chemistry and biochemistry and a member of the UCLA–DOE Institute of Genomics and Proteomics and the California NanoSystems Institute at UCLA.
