Super sponge can remove toxic dyes from industrial wastewater

Teams working on NASA's INCUS (Investigation of Convective Updrafts) mission, the first space-based survey of the dynamics of tropical convective storms, have completed assembly and tested two of the mission's small satellites, or SmallSats. Testing continues on the third SmallSat and is scheduled for completion no earlier than September ahead of a 2027 launch.

Water pollution caused by pharmaceuticals, pesticides and other organic contaminants is an increasing global issue, especially in regions with limited wastewater treatment infrastructure. A new doctoral thesis from Umea University in Sweden offers an innovative and sustainable solution by demonstrating how agricultural waste can be converted into effective materials for water purification.

On a blazing hot day in South Africa, female southern pied babblers can't think straight. The medium-sized black-and-white birds are trying to get at tasty mealworms behind a see-through barrier. On cooler days, the birds can quickly figure out that all they have to do is go around the small wall of plastic. But when the mercury goes up, the birds just keep stubbornly pecking at the barrier.

Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of the planet's environment during that time is limited. However, samples from the moon and its cratered surface hint at the period's rate of cosmic impacts.
