Strong New Evidence for a Controversial Decades-Old Theory That Explains the Odd Behaviors of Water

Study detects the critical point between 2 liquid forms of water.

Water, so ordinary and so essential to life, acts in ways that are quite puzzling to scientists. For example, why is ice less dense than water, floating rather than sinking the way other liquids do when they freeze?

Now a new study provides strong evidence for a controversial theory that at very cold temperatures water can exist in two distinct liquid forms, one being less dense and more structured than the other.

Scientists Discover Three New Species of Chameleons

An international team of herpetologists from Germany and Madagascar has discovered and described three new species of chameleons from the Calumma nasutum species group.

“The endemic lemurs and chameleons are of particular interest and biologists have been investigating these groups of animals intensively since the 19th century.”

Starship SN5 set for a static fire followed shortly by a 150-meter hop attempt

Starship SN5 is finally set to begin Raptor engine testing this weekend after a successful cryogenic proof test on July 1. If the static fire test is successful, it will clear the way for a 150-meter hop test as early as next week. The 150-meter hop will be the first test flight of a full-scale Starship tank section.
