There is one connection to the University. In the mid-1980s, someone donated a cast-iron sundial in John Harvard's name; it now sits in Hylton Park--"the Harvard park, we all call it," Gilmore says...

...evidence, the panel of scientists at the press conference cited complex chemicals found close by or inside the carbonate globules. These included polycyclic aromatic hydrocarbons (PAHS)--organic molecules that on Earth are formed when microorganisms die and decompose (but also when certain fossil fuels are burned)--and iron sulfides and magnetite, minerals that are often (but not necessarily) produced by living organisms...
...this case are said to be the byproducts of metabolic processes. The PAH molecules were recovered from cracks in the rock, which means they were probably deposited after the rock was formed, and not left behind by heating and cooling. Also present in the samples are magnetite and iron sulfide, which on Earth are associated with bacterial action. "As the number of solar systems and planets we've discovered increases," says TIME's Jeffrey Kluger, "it becomes less and less likely that we are alone in the universe. The major import of this discovery could be the realization that life...
...most striking is the Red Pyramid, known by the reddish tinge its iron oxide-rich stone takes on in the light of the setting sun. It is the first pyramid in the classic smooth-sided shape so familiar to schoolchildren. Previously, only step-sided pyramids had been built (a shape that was also seen in Mesopotamia and turned up, much later, in Latin America). It was Snefru who conceived of the more difficult smooth-sided form. "He made the intellectual jump," says Rainer Stadelmann, director of the German Archaeological Institute in Cairo. Enlisting two of his sons as architects, Snefru...
