Unlike other fruits that grow on trees, avocadoes do not ripen until harvest. An unripe avocado retains a light color, even after picking, and is quite firm when pressed and touched. The clear sign that the avocado is ripe is a darker-colored skin and it becomes softer. Sometimes it happens that it overripens when the […]

A recent conversation with a colleague moved quickly from disposable cutlery and plates to appliances. While we still love our 23-year-old washing machine and dryer, things are not built to last the way that they used to.

Can anything minimize the serious polarization among groups in countries like Israel and the US? With the global escalation in conflicts among population groups, acts of violence by residents of cities and the increasing participation of youth in civil conflicts, there appears to be an urgent need to develop science-based methods to mitigate hatred and […]

Bad breath is so embarrassing for those who suffer from it, but there are several solutions out there. One major factor is the food you eat.  A new study found that eating yogurt and other fermented foods could banish bad breath. Researchers in China say that probiotic bacteria in yogurt, sourdough bread and miso soup […]

Researchers have for years tried to discover what determines “resilience to stress,” a term describing the ability to adapt to difficult situations and to overcome adversity. Is it acquired through experience, or is there a tendency to easily recover from stress possibly ingrained in us from a very early age or even from birth? A […]
