New research led by the University of Kent has found that adolescents and older adults pay less attention to social cues in real-world interactions than young adults.

The same biases that exist for women physicians in person also exist in social media networking, a new Northwestern Medicine study reports. What's more, a previous study found women physicians are twice as likely to face sexual harassment online than men. The new study's findings speak to gender-equity issues for professional women outside medical field.

The majority of children infected with SARS-CoV-2 may not show typical symptoms such as fever, cough or shortness of breath, according to a study published in Scientific Reports, which examined data on 12,306 children with laboratory-confirmed COVID-19 across the United States.

Cooperation plays a crucial role in evolution. A team of scientists around Laura Schmid from the Chatterjee group at the Institute of Science and Technology (IST) Austria has now created a new model that shows how different kinds of cooperative strategies among humans develop. Using their unified framework, they show how an individual's experience and the reputation of others influence the emergence of successful cooperation.

Among other things, dams serve as reservoirs for drinking water, agricultural irrigation, or the operation of hydropower plants. Until now, it had been assumed that dams act as net carbon stores. Researchers from the Helmholtz Centre of Environmental Research (UFZ) together with Spanish scientists from the Catalan Institute for Water Research (ICRA) and the University of Barcelona showed that dams release twice as much carbon as they store. The study has been published in Nature Geosciences.

What The Study Did: Advertisements on videos on made-for-kids channels on YouTube, as well as the frequency of age-inappropriate ads, were analyzed in this study.

What The Study Did: This survey study examined differences between male and female physicians in the use of social media and reported career and professional benefits.

What The Viewpoint Says: Questions regarding the safety of COVID-19 vaccination for patients with cancer are explored in this article.

Researchers report the discovery of several sets of fossilized tracks, likely from the brown bear-sized Coryphodon, that represent the earliest known evidence of mammals gathering near an ocean.

Scientists exploring the drivers of Antarctic climate change have discovered a new and more efficient pathway for the creation of natural aerosols and clouds which contribute significantly to temperature increases.

A new study with zebrafish shows that a deadly form of skin cancer -- melanoma -- alters the metabolism of healthy tissues elsewhere in the body. The research from Washington University in St. Louis suggests that these other tissues could potentially be targeted to help treat cancer.

Radical changes to the food system are needed to safeguard our food supply and combat malnutrition in the face of climate change, environmental degradation and epidemics, says new report.

Climate change may be accelerating the degradation of ancient rock paintings in Indonesia, including the oldest known hand stencil in the world which dates back to 39,900 years ago, according to a study published in Scientific Reports.

Fossilised footprint tracks, recently discovered within the Hanna Formation in Wyoming, USA, which have been dated to 58 million years ago, may represent the earliest evidence of mammals gathering by the sea, according to a study published in Scientific Reports. Findings suggest that mammals may have first used marine habitats at least 9.4 million years earlier than previously thought, in the late Paleocene (66-56 million years ago), rather than the Eocene (56-33.9 million years ago).

Artificial food colorants can cause disease when the immune system has become dysregulated, Icahn School of Medicine at Mount Sinai researchers report. The study, published in Cell Metabolism in May, was the first to show this phenomenon.

The once-abundant California condor briefly went extinct in the wild, with only 22 individuals living in captivity by 1982. Today, 300 condors live freely in the wild and another 200 are in captivity. But, despite the condor's struggles, a new study of the California condor genome reported in the journal Current Biology on May 13 has found a surprising amount of genetic diversity.

Scientists from Sydney and New York, inspired by Black Lives Matter, describe the critical worldwide need to improve the diversity of cells used in medical research. Currently, 95% of all human cell lines used in research are of European descent. The authors provide actionable steps, in this publication in Cell, that researchers and the biomedical community can take to promote more inclusivity in preclinical and basic science research.

Clinicians and scientists have long observed that cells in overstressed hearts have high levels of the simple sugar O-GlcNAc modifying thousands of proteins within cells. Now, researchers at Johns Hopkins Medicine have found evidence in mouse experiments that these excess sugars could well be a cause, not merely a consequence or marker of heart failure.

The relevance of pet dog biobanking in molecular research and the initiative to make pioneering steps in this field. The Hungarian Canine Brain and Tissue Bank (CBTB) was established by the research team of the Senior Family Dog Project in 2017, following the examples of human tissue banks. In a recent paper, the team reports findings, which would not have been possible without the CBTB, and may augment further progress in dog aging and biomarker research.

A new WCS study looks at the prevalence of human consumption of lemur and fossa (Madagascar's largest predator) in villages within and around Makira Natural Park, northeastern Madagascar, providing up-to-date estimates of the percentage of households who eat meat from these protected species.
