Could broccoli hold the cure to bacterial resistance to antibiotics?

So many types of bacteria have become resistant to antibiotics because the pathogens develop biofilms that protect them from being wiped.

Israeli scientists work towards curbing Candida, the yeast infection fungus

Weizmann scientists discovered that a powerful commando unit of TH17 cells capable of fighting Candida cannot be generated without crucial early support from an entirely different contingent.

 An Aire-ILC3 cell (green) "kisses" a Candida-fighting TH17 cell (red), telling it to start dividing (top row), but it ignores other T cells that do not specialize in fighting Candida (bottom row).

Does candy cause tooth cavities?

Sugar and sweets are considered the root of all evil with respect to dental health, but in reality they have but a small, albeit significant role in the process that leads to dental caries.

 The equation according to which candy plus teeth equal tooth cavities is fundamentally correct, but inaccurate.

A new method to determine stability of bacterial ecosystems

Study at Bar-Ilan University found that different species of bacteria can self-sustain in the same environment, depending on the strength of their interactions.

Game Theory may be useful in combatting viruses- TAU study

A 'phage game theory' exists, in which the phage receives information not only from its own host but also from neighboring bacteria.

 Bacteria which contain a "dormant" parasitic element (blue) are awakening and getting yellow in the presence of bacteria which do not contain the element (red).
