As Arctic summers warm, Earth’s northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a new study found the region has become greener, as warmer air and soil temperatures lead to increased plant growth.
A warming climate and more frequent wildfires do not necessarily mean the western United States will see the forest loss that many scientists expect. Dry forest margins may be more resilient to climate change than previously thought if managed appropriately, according to researchers.
Millions of mummified ibis and birds of prey, sacrificed to the Egyptian gods Horus, Ra or Thoth, have been discovered in the necropolises of the Nile Valley. Such a quantity of mummified birds raises the question of their origin: were they bred, like cats, or were they hunted? According to a team of scientists that carried out extensive geochemical analyses on mummies, they were wild birds.
Widespread fungal disease in plants can be controlled with a commercially available chemical that has been primarily used in medicine until now. In a comprehensive experiment scientists have uncovered a new metabolic pathway that can be disrupted with this chemical, thus preventing many known plant fungi from invading the host plant.
Researchers have identified a potential drug candidate against enterovirus 71, a common cause of hand, foot and mouth disease in infants and young children. The compound of interest is a small molecule that binds to RNA, the virus’s genetic material, and changes its 3-D shape in a way that stops the virus from multiplying without harming its human host. It’s an antiviral strategy that could be used on other hard-to-treat diseases.
Attitudes towards cannabis products for medicinal use need to change with much greater appropriate use of such products to help alleviate patients’ pain, suggests new research.
The reactive and piecemeal approach historically used to manage beaches in Hawai’i has failed to protect them. If policies are not changed, as much as 40% of all beaches on O’ahu, Hawai’i could be lost before mid-century, according to a new study.
To increase screening of chemical intolerance, researchers have developed and validated a three-question survey that can be incorporated into patient visits within a minute.
In the United States, fully stocking non-stocked and poorly stocked forests would result in an annual increase of 20 percent in the amount of carbon sequestered by forests.
