In western lowland gorillas, groups consist of several females and only one adult male, the silverback. With his impressive body size, he protects his group against predators and other adult males. Females rely on this protection and never travel alone, however they may change groups multiple times during their lives. "Female gorillas seem to have different strategies when it comes to reproduction and transfer", says Marie Manguette, first author of the study.
A new study from researchers at the Johns Hopkins Bloomberg School of Public Health found that adolescents who spend more than three hours a day on social media are more likely to report high levels of internalizing behaviors compared to adolescents who do not use social media at all.
An evolution revolution has begun after scientists extracted genetic information from a 1.7 million-year-old rhino tooth - the largest and oldest genetic data to ever be recorded.
Researchers identified an almost complete set of proteins, a proteome, in the dental enamel of the rhino and the genetic information discovered is one million years older than the oldest DNA sequenced from a 700,000-year-old horse.
Coasts, oceans, ecosystems, weather and human health all face impacts from climate change, and now valuable soils may also be affected.
Climate change may reduce the ability of soils to absorb water in many parts of the world, according to a Rutgers-led study. And that could have serious implications for groundwater supplies, food production and security, stormwater runoff, biodiversity and ecosystems.
The study is published in the journal Science Advances.
Bottom Line: Adolescents who spend more than three hours a day using social media may be at higher risk for mental health problems. This observational study included a nationally representative sample of nearly 6,600 U.S. adolescents (ages 12-15) who reported time spent on social media during a typical day and who reported information about mental health problems.
A team of geneticists with a desire to understand the inner workings of genes implicated in cellular identity has discovered new biological targets that may help devise alternative therapies for cancers that are becoming resistant to existing drugs.
First discovered in fruit flies, Polycomb genes were initially studied due to their essential roles in development and their role in regulating cellular identity. They are central to the field of epigenetics, which strives to explain how many cells in our bodies - with identical sets of genes - look and behave so differently.
Using functional magnetic resonance imaging (fMRI) to monitor subjects' brain activity as they were shown images of art, architecture or natural landscapes, the team found that in the visual parts of the brain, these different types of images led to very different patterns of activity, even across images all judged by subjects to be aesthetically pleasing.
WASHINGTON, DC - The American College of Rheumatology (ACR), along with 369 other leading patient, physician, and healthcare professional organizations, sent a letter to Congress urging passage of the Improving Seniors' Timely Access to Care Act of 2019 (H.R.
EVANSTON, Ill. -- Most people have experienced the hair-raising effect of rubbing a balloon on their head or the subtle spark caused by dragging socked feet across the carpet. Although these experiences are common, a detailed understanding of how they occur has eluded scientists for more than 2,500 years.
Now a Northwestern University team developed a new model that shows that rubbing two objects together produces static electricity, or triboelectricity, by bending the tiny protrusions on the surface of materials.
Plants emit gases, called volatile organic compounds (VOCs), that enter the atmosphere, where they can interact with other natural and human-made molecules to form secondary organic aerosols (SOAs). These tiny, suspended particles influence atmospheric processes, such as cloud formation and sunlight scattering. Now, researchers reporting in ACS Earth and Space Chemistry have shown that aphid-infested Scots pine trees produce a different mixture of VOCs than healthy plants, which then leads to different SOAs.
In 2017, Scot Martin, the Gordon McKay Professor of Environmental Science and Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), envisioned a novel drone-based chemical monitoring system to track the health of the Amazon in the face of global climate change and human-caused deforestation and burning.
The iconic saguaros on Tumamoc Hill served as harbingers in new research which sought to predict how the desert species will fare in the hotter, drier climate of the future and how topography might mitigate the effects of climate change.
There are 157 organisms that form the baseline biome of a healthy human gut, according to research published in the journal PLOS ONE by investigators at the George Washington University (GW). The baseline microbial profile, called GutFeelingKB, can be expanded to 863 organisms if closely related proteomes are considered. This information will serve as a reference list for doctors, patients, and researchers, giving them an idea of what a "normal" human microbiome looks like.
MINNEAPOLIS, MN- September 11, 2019 - About one in 8,000 people have facioscapulohumeral muscular dystrophy, according to a 2014 study, which is relatively common in the world of genetic diseases. New University of Minnesota Medical School research identifies an inhibitor that protects cells from toxic effects associated with this disease in cells and mice.
In Japan Science and Technology Agency's Strategic Basic Research Programs, Dr. Masato Hirano of Sony Computer Science Laboratories and his colleagues discovered a sensorimotor function integration mechanism that enables the skillful fingering of pianists.
