In a world first, scientists have found a new way to direct stem cells to heart tissue. The findings, led by researchers at the University of Bristol and published in Chemical Science, could radically improve the treatment for cardiovascular disease, which causes more than a quarter of all deaths in the UK (1).
How do the communities of microbes living in our gastrointestinal systems affect our health? Carnegie's Will Ludington was part of a team that helped answer this question.
Spotted owl populations are in decline all along the West Coast, and as climate change increases the risk of large and destructive wildfires in the region, these iconic animals face the real threat of losing even more of their forest habitat.
Brazil's leatherback turtles are making a "gentle recovery" after 30 years of conservation efforts, new research shows. Scientists studied nesting sites in the state of Espírito Santo in eastern Brazil - the only place in the south-west Atlantic where leatherbacks regularly nest.
A new study from the University of Göttingen and international partners have analyzed the effects of Fairtrade certification on poor rural workers in Africa. The results show that Fairtrade improves the situation of employees in agricultural cooperatives, but not of workers in the smallholder farm sector, who are often particularly disadvantaged. The study was published in "Nature Sustainability".
Global sea levels are expected to rise by at least half a meter by the year 2100 due to climate change. The projected rise can affect important environmental factors such as habitat suitability and availability of light, threatening the health and survival of marine ecosystems.
An article published today in the Open Access journal GigaScience  might make you squirm if you plan to hit the beach this summer.
In a 600-ft.-long saltwater wave tank on the coast of New Jersey, a team of New Jersey Institute of Technology (NJIT) researchers is conducting the largest-ever simulation of the Deepwater Horizon spill to determine more precisely where hundreds of thousands of gallons of oil dispersed following the drilling rig's explosion in the Gulf of Mexico in 2010.
Researchers have found bullfrog tadpoles with clear signs of infection by ranavirus in Brazil. The specimens were collected from two ponds in the city of Passo Fundo, south of the country (state of Rio Grande do Sul), in November 2017. Ranavirus causes skin ulcerations, edema, and internal hemorrhage. It does not affect humans but can be lethal to amphibians and fish.
A popular imported tree that became a neighborhood favorite in the 1990s now threatens to crowd out native trees in some Eastern forests.
When an asteroid smacked into the Earth 66 million years ago, it triggered mass extinctions all over the planet. The most famous victims were the dinosaurs, but early birds, insects, and other life forms took a hit too. The collision caused clouds of ash to block the sun and cool the planet's temperature, devastating plant life.
Scientists from Sanford Burnham Prebys have created natural-looking hair that grows through the skin using human induced pluripotent stem cells (iPSCs), a major scientific achievement that could revolutionize the hair growth industry.
More than 20 percent of the five staple crops that provide half the globe's caloric intake is lost to pests each year. Climate change and global trade drive the spread, emergence, and re-emergence of crop disease, and containment action is often inefficient, especially in low-income countries.
Coral reefs face many challenges to their survival, including the global acidification of seawater as a result of rising carbon dioxide levels in the atmosphere. A new study led by scientists at UC Santa Cruz shows that at least three Caribbean coral species can survive and grow under conditions of ocean acidification more severe than those expected to occur during this century, although the density of their skeletons was lower than normal.
