Image: Hubble sees a stellar furnace

An orange glow radiates from the center of NGC 1792, the heart of this stellar furnace. Captured by the NASA/ESA Hubble Space Telescope, this intimate view of NGC 1792 gives us some insight into this galactic powerhouse. The vast swathes of tell-tale blue seen throughout the galaxy indicate areas that are full of young, hot stars, and it is in the shades of orange, seen nearer the center, that the older, cooler stars reside.

Researchers advance simple and inexpensive diagnostic blood test

In diagnostic medicine, biopsies, where a sample of tissue is extracted for analysis, is a common tool for the detection of many conditions. But this approach has several drawbacks—it can be painful, doesn't always extract the diseased tissue, and can only be used in a sufficiently advanced disease stage, making it, in some cases, too late for intervention. These concerns have encouraged researchers to find less invasive and more accurate options for diagnoses.

CLOUD at CERN reveals the role of iodine acids in atmospheric aerosol formation

In a paper published today in the journal Science, the CLOUD collaboration at CERN shows that aerosol particles made of iodic acid can form extremely rapidly in the marine boundary layer—the portion of the atmosphere that is in direct contact with the ocean. Aerosol particles in the atmosphere affect the climate, both directly and indirectly, but how new aerosol particles form and influence clouds and climate remains relatively poorly understood. This is particularly true of particles that form over the vast ocean.

Reducing biases about autism may increase social inclusion

Efforts to improve the social success of autistic adolescents and adults have often focused on teaching them ways to think and behave more like their non-autistic peers and to hide the characteristics that define them as autistic. Psychology researchers at The University of Texas at Dallas, however, have been focusing on another approach: promoting understanding and acceptance of autism among non-autistic people.
