New research is challenging the age-old adage that money can’t buy happiness.

The study, led by researchers at the University of British Columbia and Harvard Business School, suggests that using money to buy free time— such as paying to delegate household chores like cleaning and cooking— is linked to greater life satisfaction.

Tiny eel-like creatures called nematodes are surrounding us. While they can be free-living (a cup of soil or seawater contains thousands), the most well-known nematodes are the parasitic kind that wreak havoc in people, animals and plants.

Turbulence, the violently unruly disturbance of plasma, can prevent plasma from growing hot enough to fuel fusion reactions. Long a puzzling concern of researchers has been the impact on turbulence of atoms recycled from the walls of tokamaks that confine the plasma. These atoms are neutral, meaning that they have no charge and are thus unaffected by the tokamak’s magnetic field or plasma turbulence, unlike the electrons and ions — or atomic nuclei — in the plasma.  Yet, experiments have suggested that the neutral atoms may be significantly enhancing the edge plasma turbulence, hence the theoretical interest in their effects.

Researchers at North Carolina State University have found a specific gene in corn that appears to be associated with resistance to two and possibly three different plant leaf diseases.

A new way of producing the seasonal flu vaccine could speed up the process and provide better protection against infection.
