Asteroid that Killed the Dinosaurs also Wiped out the ‘Obamadon’

The asteroid collision widely thought to have killed the dinosaurs also led to extreme devastation among snake and lizard species, according to new research — including the extinction of a newly identified lizard Yale and Harvard scientists have named Obamadon gracilis.

“The asteroid event is typically thought of as affecting the dinosaurs primarily,” said Nicholas R. Longrich, a postdoctoral associate with Yale’s Department of Geology and Geophysics and lead author of the study. “But it basically cut this broad swath across the entire ecosystem, taking out everything. Snakes and lizards were hit extremely hard.” (more…)

Crowdsourcing Site Compiles New Sign Language for Math and Science

A multimedia feature published this week in the New York Times, “Pushing Science’s Limits in Sign Language Lexicon,” outlines efforts in the United States and Europe to develop sign language versions of specialized terms used in science, technology, engineering and mathematics.

The article shares newly defined signs for terms like “light-year,” “organism” and “photosynthesis.” It also describes a successful crowdsourcing effort started at the University of Washington in 2008 that lets members of the deaf and hard-of-hearing community build their own guide to the evolving lexicon of science.

“It’s not a dictionary,” explained Richard Ladner, a UW professor of computer science and engineering. “The goal of the forum is to be constantly changing, a reflection of the current use.” (more…)

UCLA Doctors Remove Man’s Heart, Replace it with Total Artificial Heart

Portable power supply allows patient to go home while he awaits new heart

Imagine living without a heart. It is possible — if you have a new artificial heart pumping blood through your body. You can even go to the supermarket, watch your kid’s soccer game or go on a hike.

Ronald Reagan UCLA Medical Center has performed its first procedure to remove a patient’s diseased heart and replace it with a SynCardia Temporary Total Artificial Heart.

Chad Washington, 35, underwent the seven-hour transplant surgery at UCLA on Oct. 29, led by Dr. Murray Kwon, an assistant professor of cardiothoracic surgery. (more…)

Mastering Scientific Mumbo Jumbo

About the video: Discusses the interaction between abiotic and biotic factors. The style of the animation is influenced by The Common Craft Show.

Warning: This class will teach students to translate scientific mumbo jumbo into understandable phrases.

Michigan State University’s first, free Massive Open Online Course, or MOOC, also promises to then teach students “to speak mumbo jumbo and amaze your friends.” (more…)

NASA’s GRAIL Creates Most Accurate Moon Gravity Map

PASADENA, Calif. — Twin NASA probes orbiting Earth’s moon have generated the highest resolution gravity field map of any celestial body.

The new map, created by the Gravity Recovery and Interior Laboratory (GRAIL) mission, is allowing scientists to learn about the moon’s internal structure and composition in unprecedented detail. Data from the two washing machine-sized spacecraft also will provide a better understanding of how Earth and other rocky planets in the solar system formed and evolved.

The gravity field map reveals an abundance of features never before seen in detail, such as tectonic structures, volcanic landforms, basin rings, crater central peaks and numerous simple, bowl-shaped craters. Data also show the moon’s gravity field is unlike that of any terrestrial planet in our solar system. (more…)

Adolescents Under Pressure to Speak ‘Properly’

As adolescents transition to adulthood, the pressure to meet adult expectations – such as speaking properly – may be greater than expected, according to a new study by a Michigan State University researcher.

Suzanne Evans Wagner, assistant professor of linguistics in the College of Arts and Letters, has proven for the first time that language changes with age in addition to community pressures. And, surprisingly, college and post-high school ambitions play a huge role. (more…)
