*The hotter it gets, the smaller the animal?*

When Sifrhippus sandae, the earliest known horse, first appeared in the forests of North America more than 50 million years ago, it would not have been mistaken for a Clydesdale.

It weighed in at around 12 pounds–and it was destined to get much smaller over the ensuing millennia.

Sifrhippus lived during the Paleocene-Eocene Thermal Maximum (PETM), a 175,000-year interval of time some 56 million years ago in which average global temperatures rose by about 10 degrees Fahrenheit. (more…)

*How Bob Vince changed the world*

Where does it begin, the act of becoming a scientist? Perhaps with a bowling ball, its finger holes packed with explosives, which when detonated, launch the ball into the air, cracking the otherwise pristine concrete walkway of your childhood home in four places, much to the consternation of your father. Or maybe with an explosion of homemade rocket fuel in your basement chemistry lab that scares your mother half to death. And all this before the troublesome teen years.

Bob Vince can’t be sure where his becoming a scientist began. But where it led changed the world. (more…)

Pregnant Primates Miscarry When New Male Enters Group

ANN ARBOR, Mich.— Pregnant female geladas show an unusually high rate of miscarriage the day after the dominant male in their group is replaced by a new male, a new University of Michigan study indicates.

The “Bruce effect” – in which pregnant females spontaneously miscarry after being exposed to an unfamiliar male – has been found repeatedly in laboratory rodents. However, no conclusive evidence for this effect had ever been demonstrated in a wild population prior to this study. Geladas are Old World monkeys that are close relatives of baboons. (more…)

Berkeley Lab Researchers Find New Evidence on How Cholesterol Gets Moved from HDLs to LDLs

Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have found new evidence to explain how cholesteryl ester transfer protein (CETP) mediates the transfer of cholesterol from “good” high density lipoproteins (HDLs) to “bad” low density lipoproteins (LDLs). These findings point the way to the design of safer, more effective next generation CETP inhibitors that could help prevent the development of heart disease. (more…)

This year a series of events around the world will celebrate the work of Alan Turing, the father of the modern computer, as the 100th anniversary of his birthday approaches on June 23. In a book chapter that will be published later this year, mathematician Robert Soare, the founding chairman of the University of Chicago’s computer science department, will propose that Turing’s achievement was artistic as well as scientific.

Some of the figures scientists create are stunning. Others are not – mismatched fonts, poorly aligned tables, clashing colors. Many fall somewhere in between. A deluge of data presents a challenge to amateur designers, often resulting in a cluttered presentation that can crowd out the figure’s main message. (more…)
