Warming temperatures are driving Arctic greening

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.

Forest margins may be more resilient to climate change than previously thought

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.

Wild birds as offerings to the Egyptian gods

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.

New drug candidate found for hand, foot and mouth disease

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.
