Researchers identified six consecutive waves of mammal species diversity in North America, linked to climate change and temperature fluctuations. The study found correlations between species diversity and global paleotemperatures, shedding light on the impact of climate change on mammal evolution over millions of years.
A molecular 'maturation clock' has been identified that regulates the number of branches in tomato plants, leading to increased flower and fruit production. Manipulating this clock could provide agricultural benefits by slowing down branching, resulting in more fruits.
A new study by UC Davis and NOAA reveals that small oil spills can devastate marine life, including commercially important species like Pacific herring. The research found that components of Cosco Busan bunker oil accumulated in embryos and interacted with sunlight to kill them.
A recent study by Ohio State University researchers suggests that a child's emotional relationship with their mother during toddler years may affect their risk of becoming obese as a teenager. The study found that children with poorer-quality early maternal-child relationships were more likely to be obese at age 15.
A study published in PNAS found that Pacific herring embryos in shallow waters died at high rates after the 2007 Cosco Busan oil spill, highlighting an interaction between sunlight and chemicals in oil. The findings suggest oil threats in sunlit habitats, particularly for translucent animals like herring embryos.
Researchers found that women with celiac disease experience higher rates of stress, depression, and disordered eating compared to the general population. Despite managing a gluten-free diet, they often struggle with body image, weight, and shape issues.
Allergy tests are not magic bullets for diagnosis, according to new guidelines from Johns Hopkins Medicine. Blood and skin tests should be used to confirm suspicion and monitor established allergies, but not as standalone diagnostic strategies. This approach aims to prevent misdiagnosis and unnecessary restrictions on patients.
