The link between climate change and migration has gained both academic and public interest in recent years. Many studies have found that environmental hazards affect migration. But the links are nuanced and depend on the economic and sociopolitical conditions in the respective regions of origin. So what causes people to move and where do they...
Twenty years ago treatment for HIV was a rare luxury in South Africa. Exorbitant costs and President Thabo Mbeki’s government’s fierce opposition to providing antiretroviral treatment (ART) kept it out of the public sector. They were terrible days. Many lives were lost. The environment has changed remarkably since then. The turning point came in 2004...

Meanwhile, Chinese and African officials are reviewing and reflecting on their two-decade relationship. China’s growing engagement with Africa has had a positive, albeit uneven, effect on Africa’s economic growth, economic diversification, job...
Since the COVID-19 pandemic began, space- and ground-based observations have shown that Earth’s atmosphere has seen significant reductions in some air pollutants. However, scientists wanted to know how much of that decline can be attributed to changes in human activity during pandemic-related shutdowns, versus how much would have occurred in a pandemic-free 2020. Using...
Many diseases, such as COVID-19, have made the jump from animals to people with serious consequences for the human host. An international research team, including researchers from the University of Göttingen, says that more epidemics resulting from animal hosts are inevitable unless urgent action is taken. In order to protect against future pandemics which might...
More than half of all in-hospital deaths due to COVID-19 during the first six months of 2020 were among Black and Hispanic patients, according to a new study led by researchers at the Stanford University School of Medicine and Duke University. The researchers did not find any racial or ethnic differences in mortality rates among...
UCLA researchers using a model of airway tissue created from human stem cells have pinpointed how smoking cigarettes causes more severe infection by SARS-CoV-2, the virus that causes COVID-19, in the airways of the lungs. The study, led by scientists at the Broad Center of Regenerative Medicine and Stem Cell Research at UCLA and published...
Betial Asmerom, a fourth-year medical student at the University of California-San Diego, didn’t have the slightest interest in becoming a doctor when she was growing up. As an adolescent, she helped her parents — immigrants from Eritrea who spoke little English — navigate the health care system in Oakland, California. She saw physicians who were...
Movie ratings can determine a movie’s appeal to consumers and the size of its potential audience. Thus, they have an impact on a film’s bottom line. Typically, humans do the tedious task of manually rating a movie based on viewing the movie and making decisions on the presence of violence, drug abuse and sexual content....
In a controlled study of smokers, nonsmokers, and e-cigarette users, University of North Carolina School of Medicine researchers found that e-cigarette users exhibited significantly altered immune responses to a model of influenza virus infection, suggesting increased susceptibility to disease. The findings, published in the American Journal of Respiratory Cell and Molecular Biology, show that vaping changes...
