Effective new drugs and screening would make hepatitis C a rare disease by 2036, according to a new computer simulation conducted by The University of Texas MD Anderson Cancer Center and the University of Pittsburgh Graduate School of Public Health. 

Hepatitis C, a virus transmitted through the blood, is spread by sharing of needles, the use of contaminated medical equipment, and by tattoo and piercing equipment that has not been fully sterilized. Those at the highest risk for exposure are baby boomers – people born between 1946 and 1965. Widespread screening of the U.S. blood supply for hepatitis C began in 1992. A majority of people were infected through blood transfusions or organ transplants before 1992.

Money can't make you happy but perhaps math can predict how much less unhappy you will be than if you lived in poverty.

The happiness of over 18,000 people worldwide has been predicted by a mathematical equation, with results showing that moment-to-moment happiness reflects not just how well things are going, but whether things are going better than expected.

Though being overweight and obese is linked to many health issues, everything from sleep apnea and an incredibly broad metabolic syndrome designation to stranger categories like pre-diabetes, there are lots of instances where obese people survive better and live longer. Scholars term it a paradox but in reality weight and BMI are not magic bullets, curing them will not stop diseases nor will having them be a death sentence.

Tomorrow's commercial refrigeration systems, such as those in supermarkets, could be cooled by carbon dioxide instead of hydrofluorocarbons.

Hydrofluorocarbons are a greenhouse gas that is nearly 4,000 times more potent than CO2 and a future with less of them could be important because millions of pounds of HFCs leak into the environment every year, said Brian Fricke, a researcher in Oak Ridge National Laboratory's Building Equipment Research Group.

To address the problem, Fricke and colleagues are experimenting with CO2 and other refrigerants, including a hydrofluoroolefin called R1234yf.

People routinely edit photos, to take out red eyes or knock five percent of the width off of their bodies - but soon editors will have an extra dimension to work with. People will be able to turn or flip objects any way they want, even exposing surfaces not visible in the original photograph.

A chair in a photograph of a living room, for instance, can be turned around or even upside down in the photo, displaying sides of the chair that would have been hidden from the camera, yet appearing to be realistic.

Antibacterial compounds have obviously saved many lives but there isn't much reason worried parents are being told they need them in every bathroom in the house. 

Compounds like triclosan and triclocarban have become ubiquitous, and not just among the wealthy progressive elites who want other kids to have vaccines but not their own special snowflakes, it's more difficult to find a hand soap without triclosan on store shelves. The compounds are used in more than 2,000 everyday products marketed as antimicrobial, including toothpastes, soaps, detergents, carpets, paints, school supplies and even toys.
