A new tack for slack: motivate workers

A new study by the University of Texas at Austin found that acknowledging employees' efforts, rather than their abilities, boosts overall productivity in companies with remote workers. Praising effort-focused messages, especially those that are personally identifiable, can have a significant impact on employee motivation and performance.

Urbanization has impacted the population genetic structure of the Eurasian red squirrel in Japan within a short period of 30 years

A 30-year study reveals urbanization has decreased genetic diversity and increased genetic distance among Eurasian red squirrels in Japan. Gene flow between urban and rural populations remains through green spaces, but urban areas have become genetically isolated.

Uptick in drug overdose rates is widely reported especially among young women

A significant increase in drug overdose rates was recorded in Colombia between 2010 and 2021, with a notable rise among young women. The study found that the pandemic contributed to higher levels of anxiety and mental health problems, leading to overuse of drugs, particularly tranquilizers/sedatives/antidepressants.
