• Human ‘Organs-on-Chips’ as replacements for animal testing

  Jessica Taylor Science & Technology

  Wyss Institutes Founding Director Donald E. Ingber, M.D., Ph.D., kicked off SLAS2015 by focusing on the engineering of human "Organs-on-Chips" to a filled room of SLAS attendees Feb. 9. Researchers, along with Ingber, have created this innovative technology. Organs-on-a-Chip is a cell culture device — crystal clear with flexible polymers and the size of a computer memory stick — that contains hollow channels lined by living cells and tissues that imitate human cellular response far more effectively and realistically than Petri dish cultures.

• The power of observation

  Pamela Hill Education

  How do we know that a student is learning? What behaviors must they demonstrate for the teacher to draw the conclusion that the student has learned? Who determines learning? The teacher, the curriculum and the standards do. The current measure of learning is assessment. The student must indicate what they know by answering questions in a test format. However, there is a piece missing that is important to determine if a student has learned and is learning.

• CMS plans to shorten meaningful use Stage 2 to 90 days

  Scott E. Rupp Healthcare Administration

  The Centers for Medicare & Medicaid Services buckled, or so it seems. After much conjecture, gesturing and soapbox shouting from healthcare leaders, it looks like the reporting period for sending data collected in the electronic health record as part of meaningful use Stage 2 will be shortened from 365 days to 90. According to SearchHealthIT, "The time and money required to attest for a 365-day reporting period gave heartburn to many hospitals and physicians."

• It’s time to redefine the credit hour

  Brian Stack Education

  Recently, a hot topic on the Web has been the Carnegie Unit. Also referred to as credit hours or student hours, the system has come under scrutiny by many in the educational community who believe that a major shortcoming with the model is its inability to link "seat time" with actual learning. Last month, the Carnegie Foundation for the Advancement of Teaching published a new study entitled "The Carnegie Unit: A Century-Old Standard in a Changing Educational Landscape." Interestingly, the Foundation agreed that the time had come to redefine the credit hour.

• 9 tips to succeed at a career fair

  Linchi Kwok Travel, Hospitality & Event Management

• What you need to know about maintaining a 944

  Skip Kuhn Transportation Technology & Automotive

  944s are great cars that can be had at a really reasonable price. What seems to cause consternation among some first-time buyers is the cost of ownership when things like timing belts and clutches come due for service. That's when the grumbling begins. Porsche cars require Porsche maintenance, new, used or otherwise.

• The sweet spot for workout quantity

  Natalie Thomas Sports & Fitness

  Data show that New Year's resolutions start to fizzle during the third week in January. Many workout resolutions have started to waver now that we've coasted into February. How can we find that healthy balance between enough and too much exercise? A new report published in the Journal of the American College of Cardiology states that people who push their exercise too far may be just as unhealthy as inactive people. This study shouldn't encourage couch potatoes to stay put, though.

• The .30 Carbine: A light but useful cartridge

  John McAdams Law Enforcement, Defense & Security

  Designed by Winchester for the military in the early 1940s, the .30 Carbine cartridge was designed to be "more than a pistol, but less than a rifle." Used by the United States military in World War II, Korea and Vietnam, the .30 Carbine also became very popular among civilian hunters and shooters. Though it is a great cartridge under the appropriate conditions, the .30 Carbine is probably one of the most underrated light rifle cartridges in the United States.

• Out-of-autoclave here to stay for high-quality composites

  Aldo Crugnola, Nick Schott and Don Rosato Engineering

  The manufacturing of high-quality structural composite components for aerospace applications has historically involved autoclave curing, a time-consuming, high-labor, and capital-intensive manufacturing process. As the aerospace and defense industries look to lower costs, composite parts manufacturers are searching for low-cost alternatives to traditional autoclave molding processes that can produce the same mechanical performance that autoclave curing provides. Both commercial and academic research and development have been focusing on a variety of liquid molding or low-pressure consolidation processes to meet this need for lower cost "out-of-autoclave" composite molding.
