Some metals are in liquid form, the prime example being mercury. But there are also enormous quantities of liquid metal in the Earth's core, where temperatures are so high that part of the iron is molten and undergoes complex flows. A team has now simulated a similar process in the laboratory and made a surprising discovery: Under certain circumstances, the flow of liquid metal is far more...

A research team has mapped out the development and genetic trajectory of previously understudied macrophages associated with the central nervous system. Among other things, the team found that meningeal macrophages are formed during gestation and develop in the same way as microglia, while perivascular macrophages develop after birth. Their new insights could pave the way for better understanding...

According to a new study, long-term insomnia symptoms can pose a risk of poorer cognitive functioning later in life. This is another reason why insomnia should be treated as early as possible.

Satellites and drones can provide key information to protect pollinators. A new study examines new ways of using these technologies to track the availability of flowers, and says this could be combined with behavioral studies to see the world through the eyes of insects.

A substantial part of the trade in blood pythons in Indonesia is illegal and underreported, a new study has found. The study found no convincing evidence that the harvest of blood pythons in the area is sustainable. Even though the harvest and trade of the species are regulated by a quota system, misdeclared, underreported and illegal trade remain a serious challenge to its sustainable...

Scientists have shown an existing drug may reduce damage after spinal cord injury, by blocking the inflammatory response in the spinal cord.
