Medical News Today – HIV progression ‘spreads like Internet malware’ and requires early treatment
The experts at University College London (UCL) have created a new model for HIV progression. From this model they noticed that HIV spreads through the body using two methods:

  1. Via the bloodstream
  2. Directly between cells.

This method is similar to how computer worms spread through both the Internet and local networks to infect as many computers as possible.
The new HIV progression model for this “hybrid spreading” accurately predicts patients’ progression from HIV to AIDS in a major clinical trial.
Detailed sample data from 17 London-based patients were used to verify the model, indicating that “hybrid spreading” provides the most suitable explanation for HIV progression and highlights the benefits of early treatment.

The Hill – Vegan diet best for planet
A federal panel that helps set federal dietary guidelines is recommending Americans eat less meat because it’s better for the environment, sparking outrage from industry groups representing the nation’s purveyors of beef, pork and poultry.
The Dietary Guidelines Advisory Committee, a federally appointed panel of nutritionists created in 1983, decided for the first time this year to factor in environmental sustainability in its recommendations. They include a finding that a diet lower in animal-based foods is not only healthier, but has less of an environmental impact.
The meat industry is lashing back, contending the panel has neither the authority nor the expertise to make such a judgment.

Reuters – Less than recommended physical activity may still lengthen life
Staying active, even only slightly, confers major longevity benefits, researchers say.
During many years of follow-up, people who did less than the minimum recommended amount of physical activity still had a considerable decrease in risk of death compared to people who did no activity at all, in a new analysis of six studies.
“Our findings support the 2008 Physical Activity Guidelines for Americans, which recommend a minimum of 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity activity per week for “substantial” health benefit, and suggest “additional” benefit with more than double the exercise minimum,” said lead author Hannah Arem of the National Cancer Institute in Bethesda, Maryland.
