Despite free health care, household income affects chronic disease control in kids

Researchers at the University of Montreal have found that the glycated hemoglobin levels of children with type 1 diabetes followed at its affiliated Sainte-Justine Mother and Child University Hospital (CHU Sainte-Justine) is correlated linearly and negatively with household income. Glycated hemoglobin is the binding of sugar to blood molecules – over time, high blood sugar levels lead to high levels of glycated hemoglobin, which means that it can be used to assess whether a patient properly controls his or her blood glucose level. “Our study highlights a marked disparity between the rich and the poor in an important health outcome for children with type 1 diabetes, despite free access to health care”, explained Dr. Johnny Deladoëy, who led the study.

Rocket powered by nuclear fusion could send humans to Mars

Human travel to Mars has long been the unachievable dangling carrot for space programs. Now, astronauts could be a step closer to our nearest planetary neighbor through a unique manipulation of nuclear fusion, the same energy that powers the sun and stars.

University of Washington researchers and scientists at a Redmond-based space-propulsion company are building components of a fusion-powered rocket aimed to clear many of the hurdles that block deep space travel, including long times in transit, exorbitant costs and health risks. (more…)

Carbon’s role in atmosphere formation

A new study in Proceedings of the National Academy of Sciences suggests that the way carbon moves from within a planet to the surface plays a big role in the evolution of a planet’s atmosphere. If Mars released much of its carbon as methane, for example, it might have been warm enough to support liquid water.

PROVIDENCE, R.I. [Brown University] — A new study of how carbon is trapped and released by iron-rich volcanic magma offers clues about the early atmospheric evolution on Mars and other terrestrial bodies. (more…)

Bugs produce diesel on demand

It sounds like science fiction but a team from the University of Exeter, with support from Shell, has developed a method to make bacteria produce diesel on demand.

While the technology still faces many significant commercialisation challenges, the diesel, produced by special strains of E. coli bacteria, is almost identical to conventional diesel fuel.

This means that it does not need to be blended with petroleum products as is often required by biodiesels derived from plant oils. It also means that the diesel can be used with current supplies in existing infrastructure because engines, pipelines and tankers do not need to be modified. Biofuels with these characteristics are being termed ‘drop-ins’. (more…)

Prisoners who are psychopaths lack the basic neurophysiological “hardwiring” that enables them to care for others, according to a new study by neuroscientists at the University of Chicago and the University of New Mexico. (more…)

Scientists map elusive 3-D structure of telomerase enzyme, key actor in cancer, aging

Like finally seeing all the gears of a watch and how they work together, researchers from UCLA and UC Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a three-dimensional structure.

The creation of the first complete visual map of the telomerase enzyme, which is known to play a significant role in aging and most cancers, represents a breakthrough that could open up a host of new approaches to fighting disease, the researchers said. (more…)

UA Researchers Solve Mystery of Lincoln’s Funeral Train

With the 2015 sesquicentennial of Abraham Lincoln’s death approaching, interest is rising, and with new tools, UA researchers have turned their attention to one of the last remaining mysteries about what reportedly was the largest traditional funeral in American history – the train’s color.

A trove of information exists about Abraham Lincoln’s funeral, which drew millions of mourners during a two-week railway procession across the Northern states.

But until now, the precise color of the president’s railcar had been lost to history. (more…)

Decreasing emissions of black carbon, methane and other pollutants makes a difference

With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow sea level rise this century.

Scientists found that reductions in four pollutants that cycle comparatively quickly through the atmosphere could temporarily forestall the rate of sea level rise by roughly 25 to 50 percent.

The researchers focused on emissions of four heat-trapping pollutants: methane, tropospheric ozone, hydrofluorocarbons and black carbon. (more…)
