Now the challenge is to ensure that these findings on #UPFs inform policies while acknowledging the complexities of cooking and its relationship to gender, socioeconomic status, and individual choices.

A β€˜tropical’ disease is spreading in American wildlife This neglected tropical disease is no longer confined to the tropics. It’s here, in the United States, spreading silently in wildlife.

β€œIn the heart of Illinois, while researching wildlife disease, I made a discovery that stunned me: More than half of the raccoons I sampled were infected with Trypanosoma cruzi, the parasite that causes Chagas’ disease… It’s here, in the United States, spreading silently in wildlife.”

Tomato fruit cracking

Tomato fruit cracking

TOMATO TUESDAY: Growth cracks on tomato can be caused by dry weather followed by excessive watering or a significant period of rainfall. Basically, plants get too much water too fast and the skin can’t stretch to take on the extra fluid resulting in fruit cracking to alleviate pressure #Tomato πŸ§ͺ

Bacterial spot on peach is caused by the bacterium Xanthomonas campestris pv. pruni. The disease appears as small lesions that turn reddish-brown or black leading to shot holes as the leaf tissue dries & drops out. Severe infections can cause defoliation, weakening the tree #Bacteria πŸ§ͺ

Antarctic phytoplankton communities restructure under shifting sea-ice regimes - Nature Climate Change The authors use a machine learning approach and in situ pigment samples to identify summer shifts (1997–2023) in the abundance and composition of Antarctic phytoplankton. While smaller phytoplankton g...

🧊 Antarctic sea-ice shifts are reshaping life in the ocean

A 25-year study shows major changes in phytoplankton: fewer diatoms, more cryptophytes and haptophytes. This could weaken the krill food web and carbon storage in the deep ocean.

Avoid planting low wet areas. Dont over water. Avoid area with a history of the disease. Nothing you can spray for this bacterial disorder. Programs are underway to develop resistant varieties.
