Reminding people of the dangers of diseases boosts vaccine acceptance
Science Focus
original post »The US has seen an increasing number of outbreaks from some communicable diseases that can easily be controlled through vaccination, but there has been a parallel increase in the number of parents who are choosing not to vaccinate their children. In part because there are a lot of reasons that the vaccination rate is dropping (unfounded fears about vaccine safety and mistrust of pharmaceutical companies are two), it's not clear that a single intervention will reverse this trend.
A pair of papers released this week looked at two very different approaches, one focused on individuals and a second at state-level laws. They show that it's relatively simple to change both attitudes and actions on vaccination.
Fighting back against the backfire effect
The first study, from PNAS, looks at individuals' attitudes toward vaccines. You might think that countering unfounded fears about vaccine safety would be a simple matter of showing people the safety data, but it doesn't work like that. Doing so risks what's called the "backfire effect," described in the paper as follows: "Direct attempts to dispel myths [regarding vaccine safety] risk perpetuating those myths through their repetition, as this repetition breeds familiarity and may strengthen people’s memory for incorrect information."

Milky Way Galaxy - Our Beautiful Neighborhood Poster

Milky Way Galaxy - Our Beautiful Neighborhood In this spectacular image, observations using infrared light and X-ray light see through the obscuring dust and reveal the intense activity near the galactic core. Note that the center of the galaxy is located within the bright white region to the right of and just below the middle of the image. The swirling core of our galaxy harbors hundreds of thousands of stars that cannot be seen in visible light. These stars heat the nearby gas and dust. These dusty clouds glow in infrared light and reveal their often dramatic shapes. Some of these clouds harbor stellar nurseries that are forming new generations of stars. Like the downtown of a large city, the center of our galaxy is a crowded, active, and vibrant place. The galactic center is marked by the bright patch in the lower right. Along the left side are large arcs of warm gas that have been heated by clusters of bright massive stars. Winds and radiation from these stars create the complex structures seen in the gas throughout the image.This sweeping panorama is one of the sharpest infrared pictures ever made of the galactic center region. Hundreds of small dots show emission from material around black holes and other dense stellar objects. A supermassive black hole -- some four million times more massive than the Sun -- resides within the bright region in the lower right. The diffuse X-ray light comes from gas heated to millions of degrees by outflows from the supermassive black hole, winds from giant stars, and stellar explosions. This central region is the most energetic place in our galaxy.

The Cat's Eye Nebula or NGC 6543, is a planetary nebula in the constellation of Draco. Structurally, it is one of the most complex nebulae known, with high-resolution Hubble Space Telescope observations revealing remarkable structures such as knots, jets, bubbles and sinewy arc-like features. In the center of the Cat's Eye there is a bright and hot star; around 1000 years ago this star lost its outer envelope, producing the nebula. - Wikipedia.org. Image by NASA.

Discovery in growing graphene nanoribbons could enable faster, more efficient electronics
more »
Graphene, an atom-thick material with extraordinary properties, is a promising candidate for the next generation of dramatically faster, more energy-efficient electronics. However, scientists have struggled to fabricate the material into ultra-narrow strips, called nanoribbons, that could enable the use of graphene in high-performance semiconductor electronics. Now engineers have discovered a way to grow graphene nanoribbons with desirable semiconducting properties directly on a conventional germanium semiconductor wafer.
