What do Velcro, Tang, penicillin, the structure of DNA and the World Wide Web have in common?
They all involved serendipitous discoveries—chance discoveries made by alert, curious scientists who were looking for other things when they happened across a fortuitous finding. Rather than ignoring their accidental discoveries, these curious, open-minded scientists harnessed their luck. “Chance favors only the prepared mind,” as Louis Pasteur put it. (more…)
ANN ARBOR — Funneling a steady stream of diversions straight to your pocket, smartphones are often cast as the ultimate distractors. But a University of Michigan engineering professor sees potential for them to be something quite the opposite.
What if they could act as mentors in mindfulness, helping users stay attentive in order to achieve particular goals? (more…)
Planetary scientists have identified water ice and unusually dark deposits within permanently shadowed areas at Mercury’s north pole.
Using data collected by NASA’s MESSENGER spacecraft, a team from UCLA crafted the first accurate thermal model of the solar system’s innermost planet, successfully pinpointing the extremely cold regions where ice has been found on or below the surface.
The researchers say the newly discovered black deposits are a thin crust of residual organic material brought to the planet over the past several million years through impacts by water-rich asteroids and comets. (more…)
*RNA editing is a key step in gene expression. Scientists at Brown University report in Nature Methods that they have engineered a gene capable of visually displaying the activity of the key enzyme ADAR in living fruit flies.*
PROVIDENCE, R.I. [Brown University] — To track what they can’t see, pilots look to the green glow of the radar screen. Now biologists monitoring gene expression, individual variation, and disease have a glowing green indicator of their own: Brown University biologists have developed a “radar” for tracking ADAR, a crucial enzyme for editing RNA in the nervous system.
The advance gives scientists a way to view when and where ADAR is active in a living animal and how much of it is operating. In experiments in fruit flies described in the journal Nature Methods, the researchers show surprising degrees of individual variation in ADAR’s RNA editing activity in the learning and memory centers of the brains of individual flies.

*University-Vikings partnership helps children lead healthier lives*
Even if you’re not a football fan, you’ve probably noticed the Minnesota Vikings in the news a lot, whether it’s in regard to the 2011 season or their push for a new stadium.
What often goes unnoticed is the team’s record of community engagement and financial benevolence. Over the years the Vikings have given millions to the local community.(more…)
