They found that three proteins - formin, twinfilin, and capping protein - work together to regulate the activity of actin filaments, allowing for more precise control of cellular movement.
A new study by Emory University neuroscientists reveals that oxytocin plays a key role in male zebra finches' learning to sing by imitating their elders. The hormone influences young birds' preference for certain 'voice coaches', shedding light on the neural underpinnings of social vocal learning.
The new Winship Cancer Institute at Emory Midtown offers a unique patient-centered, multidisciplinary cancer care model integrated with innovative research. The $200 million gift from the Robert W. Woodruff Foundation enabled the construction of a state-of-the-art facility featuring five 'care communities' and 80 inpatient beds.
A team of researchers developed a dynamical model that explains how animals learn over time, contradicting previous theories. The multi-dimensional model shows that learned associations are not mediated solely by strength but by multiple nearly independent pathways.
A new study by Emory University researchers found that asymptomatic individuals account for a significant proportion (74%) of dengue infections in an Amazonian city. The 'super spreader' spaces, where infected people frequent, are crucial in predicting and controlling outbreaks.
A new genomic study found signs of TB adaptation in ancient Andean populations, thousands of years before European contact. The study suggests that Indigenous people in present-day Ecuador developed an immune response to tuberculosis around 3,000 years ago, when agriculture began proliferating in the region.
A study led by Emory University found that young, single, and less educated men were disproportionately deported during the Trump administration, despite differing rhetoric. The research analyzed data from three administrations and suggests that immigration policies have unintended consequences on immigrant groups.
A study by Emory University researchers found that extracts from two wild plants, tall goldenrod and eagle fern, inhibited the ability of the SARS-CoV-2 virus to infect living cells. The active compounds are present in miniscule quantities, making it ineffective for self-treatment, but may hold promise as medicines against COVID-19.
Researchers at Emory University used machine learning and fMRI to analyze a dog's brain activity while watching videos. The results show that dogs are more attuned to actions in their environment than to who or what is performing the action. This study offers proof of concept for decoding canine visual perception.
A recent study published in Frontiers in Virology suggests that chronic COVID infections are the source of variants of concern. The researchers used a mechanistic, theoretical model to study the emergence of these variants, which were found to acquire a constellation of mutations that make them more transmissible and lethal. By identif...
A new animal study finds that testosterone can foster friendly, prosocial behavior in males, in addition to aggression. The hormone appears to help animals rapidly pivot between prosocial and antisocial responses as the social world changes.
A new study analyzing 30 years of data on four major U.S. crops reveals that soil water-holding capacity is a key factor in managing heat stress due to climate change. Farmers can improve soil health by adding organic matter or using mulch to reduce evaporation.
A new study finds that climate change will make the U.S. Corn Belt unsuitable for cultivating corn by 2100, highlighting the need for significant agricultural adaptations, diversification and a shift towards more sustainable farming practices.
Whole genome sequences of ancient Uruguayan Indigenous people provide a genetic snapshot of populations before European military campaigns decimated them. The results support the theory of separate migrations into South America, contradicting the idea of a single Native American race across North and South America.
