The study, published in Functional Ecology, suggests that stress is more complex than previously thought and may be beneficial for vulnerable stages of development.
Researchers at Oregon State University have found a type of 'selfish' mitochondrial DNA in animals that is hurting the organism and affecting its chance to survive. The discovery bears similarities to damage done to human cells as they age and may provide an important new tool to study human aging.
A survey of nearly 2,000 US and Canadian science teachers found that one out of four released live animals into the wild, posing a significant risk to invasive species. The study highlights the need for educators and biological supply house owners to be aware of the potential consequences of releasing non-native species.
A new study by Oregon State University found that preschool-age children's ability to pay attention and persist on tasks is a key predictor of college completion. Children who were rated higher by their parents on these skills at age 4 had nearly 50% greater odds of getting a bachelor's degree by age 25.
Researchers at Oregon State University have developed a new technique to improve oil recovery and environmental cleanup using microbial enhanced oil recovery. The technology, which involves injecting microbes into wells to increase oil production, could make a comeback in the oil industry due to its potential for increased productivity.
Childhood obesity may be linked to disruptions in pubertal development and reproductive capacity, particularly in females. Research suggests that excess fat can affect the secretion of key hormones, including kisspeptin, and disrupt circadian clocks, leading to problems with fertility and overall health.
Scientists warn that chronic droughts like the 2000-04 event could become more frequent and severe, leading to ecosystem damage and reduced carbon sequestration. The region's ability to absorb carbon dioxide may decline by the end of the century, exacerbating global warming.

The presence of these viruses could be a contributing factor to the decline of coral reefs worldwide. Corals face various environmental threats, including warming temperatures, competition, and pollution.
A new study suggests that moderate drinking as part of a healthy lifestyle may benefit postmenopausal women's bone health by reducing the risk of osteoporosis. The researchers found an increase in blood markers of bone turnover after just two weeks of abstinence, but this effect reversed shortly after resumption of normal drinking habits.
A massive die-off of pinyon pine and juniper trees in the Southwest threatens to unleash devastating soil erosion and exacerbate water scarcity in the Colorado River basin. The trees' loss is expected to lead to increased dust storms, melting snowpacks, and reduced river flows.
Researchers found that former drug traffickers often want to quit due to safety reasons, family ties, and personal growth, but struggle to relinquish power and status. The study suggests policies addressing socioeconomic conditions, cultural values, and the demand for illicit drugs are needed to help traffickers leave the trade
A new study published in Molecular Ecology found that most southern right whales born near New Zealand's sub-Antarctic islands were fathered by local males, indicating strong local fidelity to breeding habitat. This finding suggests that the New Zealand population is relatively isolated from other populations, which could have implicat...
