Male guppies with rare color patterns have a highly significant survival advantage in the wild, surviving at 84% rate compared to 69% for common-patterned males. This phenomenon is linked to frequency-dependent survival, where rarity confers an advantage over common variants.
A new study finds that same-sex segregation can be beneficial for some students, particularly those who are resilient to stereotypes and able to moderate their behavior. However, it can also create disadvantages for others who struggle with these skills.
Researchers genetically altered mice to resist cocaine's effects, discovering that blocking dopamine transporters is crucial for producing a high. The study aims to find drugs that prevent cocaine from binding to transporters while allowing the transporter protein to function.
Researchers have identified the genes CO and FT responsible for tree flowering and reproduction, which could lead to faster breeding programs and strategies. This breakthrough may also help predict how trees will respond to climate change.
A recent study by Children's Hospital Oakland Research Institute found that pregnant women who are not anemic should take iron supplements weekly, rather than daily. This approach reduces the risk of iron overload and birth complications, while still providing benefits for iron supplementation.
Researchers Wako Yoshida and Shin Ishii explored how different cortical regions function in solving partially observable decision-making problems. They found that the anterior prefrontal cortex is involved in belief maintenance, while the medial prefrontal cortex is involved in belief back-track processes.
A new study found that calorie restriction decreases tumor necrosis factor alpha and lowers T3 levels in humans, suggesting it may slow the aging process. The researchers also found no association between body fat levels and serum T3 concentrations.
The European Society of Cardiology has released updated guidelines for managing stable angina pectoris, providing recommendations on treatment methods and risk stratification. The guidelines aim to improve the quality of life for European populations affected by cardiovascular disease.
Researchers identified three brain regions - dorsal anterior cingulate and left and right frontal operculum - as core components in creating task sets. These regions help determine which brain areas contribute to a cognitive task and when they play a part, according to the study published in Neuron.
Research suggests that moderate alcohol consumption is associated with better mental performance and reduced risk of dementia in older women. Women who reported drinking up to two or three drinks per day performed better on measures of global cognitive function, particularly in verbal skills.
A new study offers insights into the role of the hippocampus in forming and recalling memories, particularly for working memory. The researchers found that the hippocampus plays a crucial role in connecting related pieces of information, but not necessarily in long-term memory.
A new study shows that the quality of an embryo is more important than the age of a woman in determining IVF success. In older women aged 36-39, single embryo transfer (eSET) was found to have similar pregnancy and live birth rates as double embryo transfer.
A new study explores how people make medical decisions, revealing that stepping into others' shoes can lead to better choices. By considering multiple perspectives, including those of doctors, parents, and medical directors, participants made treatment decisions that were more informed than their own self-interest would suggest.
A new mechanism explains how glucose inhibits neurons that regulate wakefulness, revealing a role for previously unknown potassium ion channels. Glucose levels affect the firing rate of these neurons, shedding light on cellular pathways regulating vigilance states and energy balance.
