[7.8] Tropical trees cease to function at high temperatures, which creates a risk of destruction of tropical forests. — Business Insider

A new study reveals that tropical trees cease photosynthesis at 116 degrees Fahrenheit (46.7 degrees Celsius). With global temperatures on the rise, large sections of rainforests are at risk.

[7.8] COVID-19 increased mental health care. — The New York Times

A study published in JAMA Health Forum found that the use of mental health care significantly increased during the COVID-19 pandemic, with teletherapy playing a key role in lowering barriers to regular visits. The study analyzed insurance claims from March 2020 to August 2022 and found a 39 percent increase in mental health visits and a 54 percent increase in spending. The use of telehealth also saw a tenfold increase. The study focused on adults with employer-provided health insurance and did not cover acute or residential care. The authors believe that the increases in mental health care are likely to continue, despite potential concerns from insurers about the increased costs.

Ukrainian troops are now aiming to retake Berdiansk and other territories occupied by Russian forces.
