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.
A group of the world's leading experts in the transmission of airborne pathogens is calling for a tightened regulatory system to control air quality in buildings - as a way of reducing the spread of covid-19 and other illnesses.
Writing in the journal Science, the 40 scientists say: "A paradigm shift is needed on the scale that occurred when Chadwick's Sanitary Report in 1842 led the British government to encourage cities to organise clean water supplies and centralised sewage systems.
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.
The Antarctic Peninsula has shown some of the largest global increases in near-surface air temperature over the last 50 years, but experts have struggled to predict temperatures because little was known about how natural aerosols and clouds affect the amount of sunlight absorbed by the Earth and energy radiated back into space.
Today, the rocks of the Hanna Formation in south-central Wyoming are hundreds of miles away from the nearest ocean. But around 58 million years ago, Wyoming was oceanfront property, with large hippo-like mammals traipsing through nearshore lagoons.
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.

Scientists reveal that the deterioration of modern concrete and asphalt structures is due to the presence of trace quantities of organic matter in these structures.
Higher levels of ozone from air pollution are linked to an increased risk of developing fibroids among Black American women according to a large study published today (Friday) in Human Reproduction [1], one of the world's leading reproductive medicine journals.
People with healthier heart structure and function appear to have better cognitive abilities, including increased capacity to solve logic problems and faster reaction times, according to research led by Queen Mary University of London and the Radcliffe Department of Medicine at University of Oxford.
Dr Zahra Raisi-Estabragh, BHF Clinical Research Training Fellow at Queen Mary University of London said: "Heart disease and dementia are important and growing public health problems, particularly in ageing populations.
Cooperation as a successful strategy has evolved in both nature and human society, but understanding its emergence can be a difficult task. Researchers have to abstract interactions between individuals into mathematical formulas to be able to create a model that can be used for predictions and simulations.
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.
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 findings published by Nature Human Behaviour show that social attention undergoes age-related change, which has potential implications for how successfully we can interpret social interactions in daily life and throughout the lifespan.
Multiple studies have shown that African American women with breast cancer have lower survival rates than white women with the disease. But the association between race or ethnicity and treatment outcomes in triple-negative breast cancer -- an aggressive type of tumor that does not respond to hormonal or other targeted therapies -- has not been well defined.
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.
A new approach to genomic species delineation could impact policy and lend clarity to legislation for designating a species as endangered or at risk.
The coastal California gnatcatcher is an unassuming little gray songbird that's been at the epicenter of a legal brawl for nearly 28 years, ever since U.S. Fish and Wildlife Service listed it as threatened under the Endangered Species Act.
SAN FRANCISCO, CA--May 12, 2021--Following the minuscule movements of every cell in a petri dish would be a painstaking task for any human. But teach a set of computer programs to do the job, and they can complete it quickly and even observe things that the human eye would miss.
