New experiments conducted at Princeton University provide evidence for a decades-old theory that, in the quantum regime, an electron behaves as if it is made of two particles: one particle that carries its negative charge and the other that gives it a magnet-like property called spin. The team detected evidence for this theory in materials called quantum spin liquids.

The Antarctic ice sheet was even more unstable in the past than previously thought, and at times possibly came close to collapse, new research suggests.

University of Massachusetts Amherst neuroscientists examining genetically identified neurons in a songbird's forebrain discovered a remarkable landscape of physiology, auditory coding and network roles that mirrored those in the brains of mammals.

New research from Washington University School of Medicine in St. Louis shows that non-Hispanic African American women with triple-negative breast cancer have lower survival rates than non-Hispanic white women with this type of breast cancer. The study demonstrates the need for additional research to address disparities in cancer care and understand whether tumor biology or nonbiological reasons such as systemic racism -- or a combination of such factors -- may be driving these disparities.

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.
