Overtraining: the cause of symptoms caused by excessive physical exercise has been discovered

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

In tests with rodents, researchers from the State University of Campinas and their collaborators found that hyperactivation of the PARP1 protein after exhaustive training was associated with decreased performance, fatigue, and behavioral symptoms of overtraining. Animals treated with a drug that inhibits the molecule’s activity did not exhibit the condition.

Human fishing reshaped Caribbean reef food webs, 7000-year old exposed fossilized reefs reveal

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

A groundbreaking study of 7000-year-old exposed coral reef fossils reveals how human fishing has transformed Caribbean reef food webs: as sharks declined by 75% and fish preferred by humans became smaller, prey fish species flourished —doubling in numbers and growing larger. This unprecedented look into prehistoric reef communities shows how the loss of top predators cascaded through the entire food web, shifting the balance amongst coral reefs

Túngara frog tadpoles that grew up in the city developed faster but ended up being smaller

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

Have you ever wondered how city life affects animals like frogs? A new study reveals that urban Túngara frog tadpoles develop faster —but end up being smaller — than tadpoles from forests, probably resulting in smaller adults. This might be an adaptation to warmer urban puddles with fewer predators or to constantly changing environmental conditions in the city.

New model enables the study of how protein complex influences mitochondrial function

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

A yeast experiment conducted at a FAPESP-supported research center shows how deficiencies in the proteasome, which is responsible for eliminating damaged and non-functional proteins, affect the metabolism of mitochondria, the organelles that generate energy for cells.

New study highlights neglected dynamics of coral and algae energy use

Bermuda Institute of Ocean Sciences

A new study by the Bermuda Institute of Ocean Sciences, published in PLoS ONE, reveals that coral and algae respiration rates vary significantly throughout the day, peaking in the afternoon, contrary to the long-held assumption that respiration remains constant. Led by marine ecologist Yvonne Sawall, the research shows that relying on nighttime respiration rates underestimates daily respiration and photosynthesis by up to 23% and 18%, respectively.
