New research suggests that it's not just the volume of emails that causes stress; it's our well-intentioned habits and our need to feel in control that backfires on us.

These are some of the key findings presented next week, Thursday 7 January 2016, at the British Psychological Society's Division of Occupational Psychology annual conference in Nottingham by Dr Richard MacKinnon from the Future Work Centre. 

Two-and-a-half billion people worldwide have no access to safe, durable sanitation systems. Brian Arbogast, director of the water, sanitation and hygiene programme at the Bill & Melinda Gates Foundation, tells SciDev.Net how innovative toilet technologies and business models could help fix this — and help communities cope with the devastation of climate change.

How does climate change impact sanitation?

With sea levels rising, you have flooding that causes huge health problems. As latrines and septic tanks get flooded and waste goes into the streets and streams, it can carry a lot of disease, including cholera, dysentery and typhoid.

The problem is that the world has only one gold standard for sanitation, which is having flush toilets connected to sewer lines, that are further connected to big and expensive wastewater treatment plants. Growing cities that already have water shortages may not have enough water for everybody to bathe and cook, let alone to flush toilets. So, are these cities going to follow the same path we have taken for the last century in developed cities?

Eric Kim, a research fellow in the Department of Social and Behavioral Sciences at Harvard T.H. Chan School of Public Health, recently led the first study to look at a possible link between volunteering and health care use in older adults.

Why did you decide to study volunteering from a public health perspective?

There is a growing body of research showing that volunteering is associated with better physical health and mental health outcomes, as well as better health behaviors.

Another important reason is that the number of older adults in the U.S., and other countries, is rapidly rising. Over the next 35 years, the number of 65-year-olds is going to double. As a result, the number of chronic illnesses will likely rise causing at least two outcomes: First, there will be a large increase in the number of people suffering. Second, the rising number of illnesses is going to put a huge burden on our health care system. If volunteering does affect health care use, these findings could be used to inform new strategies for increasing preventive health screenings, lowering emergency room use and health care costs, and also enhancing the health of older adults.

It's now harder to find out where your beef or pork was born, raised and slaughtered.

After more than a decade of wrangling, Congress repealed a labeling law last month that required retailers to include the animal's country of origin on packages of red meat. It's a major victory for the meat industry, which had fought the law in Congress and the courts since the early 2000s.

Lawmakers said they had no choice but to get rid of the labels after the World Trade Organization repeatedly ruled against them. The WTO recently authorized Canada and Mexico, which had challenged the law, to begin more than $1 billion in economic retaliation against the United States.
