  • Husbands' stress increases if wives earn more than 40 per cent of household income: study
    on November 19, 2019 at 8:28 am

    Husbands are least stressed when their wives earn up to 40% of household income but they become increasingly uncomfortable as their spouse's wages rise beyond that point and are most stressed when they are entirely economically dependent on their partner, new research from the University of Bath shows. […]

  • Access to food and nutrition more limited in sub-Saharan Africa than previously estimated
    on November 19, 2019 at 8:21 am

    A survey of over six thousand sub-Saharan households shows an estimated 39% experience severely unreliable access to food. In addition, 49% have inadequate diversity in their diet, putting them at risk for micronutrient deficiencies. The study, published in Frontiers in Sustainable Food Systems, is among the largest of its kind—and also the first to correlate food access and nutrition to time of year, as well as demographic, agricultural, ecological and economic factors. […]

  • Get over it? When it comes to recycled water, consumers won't
    on November 18, 2019 at 9:53 pm

    If people are educated on recycled water, they may come to agree it's perfectly safe and tastes as good—or better—than their drinking water. They may even agree it's an answer to the critical water imbalance in California, where the northern third of the state holds 75% of the water despite 80% of the demand coming from the southern two-thirds.

  • Blowing bubbles: Scientist confirms novel way to launch and drive current in fusion plasmas
    on November 18, 2019 at 8:55 pm

    An obstacle to generating fusion reactions inside facilities called tokamaks is that producing the current in plasma that helps create confining magnetic fields happens in pulses. Such pulses, generated by an electromagnet that runs down the center of the tokamak, would make the steady-state creation of fusion energy difficult to achieve. To address the problem, physicists have developed a technique known as transient coaxial helicity injection (CHI) to create a current that is not pulsed. […]
