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…)
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…)
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…)
A new study in the journal Neuron suggests that the brain uses a different region than neuroscientists had thought to associate objects and locations in the space around an individual. Knowing where this fundamental process occurs could help treat disease and brain injury as well as inform basic understanding of how the brain supports memory and guides behavior.
PROVIDENCE, R.I. [Brown University] — Where are you?
Conventional wisdom in brain research says that you just used your hippocampus to answer that question, but that might not be the whole story. The context of place depends on not just how you got there, but also the things you see around you. A new study in Neuron provides evidence that a different part of the brain is important for understanding where you are based on the spatial layout of the objects in that place. The finding, in rats, has a direct analogy to primate neuroanatomy. (more…)
Researchers have discovered what may be the earliest dinosaur, a creature the size of a Labrador retriever, but with a five foot-long tail, that walked the Earth about 10 million years before more familiar dinosaurs like the small, swift-footed Eoraptor and Herrerasaurus.
The findings mean that the dinosaur lineage appeared 10 million to 15 million years earlier than fossils previously showed, originating in the Middle Triassic rather than in the Late Triassic period. (more…)
SAN FRANCISCO — Scattered around the Milky Way are stars that resemble our own sun—but a new study is finding that any planets orbiting those stars may very well be hotter and more dynamic than Earth.
That’s because the interiors of any terrestrial planets in these systems are likely warmer than Earth—up to 25 percent warmer, which would make them more geologically active and more likely to retain enough liquid water to support life, at least in its microbial form.
The preliminary finding comes from geologists and astronomers at Ohio State University who have teamed up to search for alien life in a new way. (more…)
Training human volunteers to control their own brain activity in precise areas of the brain can enhance fundamental aspects of their visual sensitivity, according to a new study in the Journal of Neuroscience.
This non-invasive ‘neurofeedback’approach could one day be used to improve brain function in patients with abnormal patterns of activity, for example stroke patients. (more…)
NASA funds astrobiology research by Delaware Biotechnology Institute scientist
Does life exist anywhere else in the universe? That’s the type of broad but poignant question NASA likes to ask, according to Chandran Sabanayagam, associate scientist in the Bioimaging Center at the Delaware Biotechnology Institute (DBI). And he would know, because he’s preparing to help answer it.
NASA will receive $100 billion from the federal government over the next five years to assure America is number one in space exploration, according to Astrobiology.com. As part of its push to seek new partnerships and broaden its vision, NASA is offering grants to people conducting transformational science. With this opportunity, Sabanayagam is merging his love of physics and biology. (more…)
