Do you have a right to high-speed Internet or can Internet Service Providers (ISPs) create different tiers for different customers?

In Florida and in Pennsylvania, there are toll roads. People pay the fee and get to a destination along the toll road quicker. Yet when it comes to pricing Internet connections, there is belief that everyone should have the same high-speed video streaming, regardless of what they pay. Can customers get something for nothing? 

In modern times, it seems a little strange to read claims in Europe and in U.S. cities like San Francisco that cell phone radiation is harmful to humans - but their reasoning is based on work in the 1970s which found an epidemiological association between increased risk of childhood leukemia and living near overhead power lines.

Like most epidemiology claims that find two curves going the same way and garner media attention, some skepticism is warranted, and later studies were unable to find the same connection, but the perception has held. Regardless,  groups like the International Agency for Research on Cancer have categorized low frequency magnetic fields as "possibly carcinogenic" even though a mechanism for this association has never been found.

There are too many factors and combinations of genetic traits to have any definitive cause of autism today, along with a wide range of diagnoses that add to the pool, but a new analysis has found that the autopsied brains of people who had autism share a pattern of ramped-up immune responses.

Targeted therapy with radiopharmaceuticals - radioactive compounds used in nuclear medicine for diagnosis or treatment - has a lot of potential to more effectively kill cancer cells that have migrated from primary tumors to lymph nodes and secondary organs such as bone marrow.

Disseminated tumor cells can be difficult to treat with a single targeting agent because there are dramatic differences in the number of targetable receptors in each cell.

When a large protein unfolds in a cell, it slows down and can get stuck in traffic. University of Illinois chemists now can watch the way the unfolded protein diffuses, which could provide great insight into protein-misfolding diseases such as Alzheimer's and Huntington's.

Researchers have hypothesized that an unfolded protein moves more slowly through the cell, because it would be a big, stringy mess rather than a tightly wrapped package. The team devised a way to measure how diffusion slows down when a protein unfolds using a fluorescence microscope, then used three-dimensional diffusion models to connect the protein's unfolding to its motion. 

The $105 billion organic food industry is not terribly worried about yields. Their customers are primarily wealthy and concerned more about the perception of benefit than they are cost.

But to the real evangelists, who insist that the organic process can feed the world, yield differences are a substantial hurdle to overcome. The low hanging fruit in food has already been picked, as it were, wealthy people educated by advertising are already buying organic food, and the rest of the marketplace thinks about price. So yields are a killer.
