Primary lithium batteries enable advanced medical devices to be smaller, lighter, and more feature-rich. This article showcases a number of different chemistries and features several real world applications for which these batteries are used.
The Project: An accelerated lead was needed on a lead screw in a spinal surgical device that would enable fewer turns to generate the necessary motion without increasing the load. The Solution: A custom assembly consisting of a combination metal-screw, polymer-based nut, and bushing system was provided that fit into the original device, eliminating any need for a redesign.
The board of directors at Spencer Pharmaceutical Inc. have indicated in a press release that they are in favor of the unsolicited buyout offer it received for 97 cents per share.
Enhancements in protection methods and power densities, combined with reduced costs have medical device manufacturers looking at lithium-ion battery technology to solve a number of design challenges for their portable devices. This article reviews a variety of advantages of this technology, and examines recent advances that make it well suited for this industry.
It's been 75 years since Albert Einstein decried the "spooky action at a distance" of quantum entanglement. Tom Siegfried, editor-in-chief of Science News, explains how quantum mechanics is being put to use, even though scientists still don't quite understand how it works.
Why do humans have consciousness? In his new book, Self Comes To Mind, neurologist Antonio Damasio argues that consciousness gave humans an evolutionary advantage. Damasio describes the differences between self and mind, and traces the evolutionary path of the human brain.
Harvard researchers have developed a Web tool for volunteers to record what they're doing and how they feel while doing it. The goal? To measure happiness. Doctoral student Matt Killingsworth describes some early results suggesting many people aren't "living in the moment."
Subra Suresh, former dean of engineering at MIT, was sworn in last month as director of the National Science Foundation, which doles out billions of dollars for basic research each year. Suresh talks about his priorities and how the NSF's budget is likely to fare with the new Congress.
This week, a group of scientists called the "rapid response team" has promised to speak up about climate change and take skeptics head-on, even if that means participating in political debates. But does this verge on advocacy? And is that a problem? Ira Flatow and guests discuss.
When it comes to comets, gassy is good, or at least informative, says astronomer Michael A'Hearn. NASA's Deep Impact probe has been snapping pictures of Hartley 2 -- a small comet that is spewing a lot of gas and dust for its size. What do researchers hope to learn from the comet?
Lichens grow practically everywhere, but they have been neglected by scientists for years, says James Lendemer, a lichenologist with New York Botanical Garden. Lendemer took Science Friday on a trip to the Tannersville Cranberry Bog in Pennsylvania to explore the diversity of lichens living there.
Waltham-based diagnostics company Interleukin Genetics Inc. has reported that it has significantly narrowed its loss due to increased sales of its genetics tests.
Foundation Medicine Inc. has appointed Maureen Cronin, a former VP of translational research at Genomic Health Inc., in the newly created role of senior vice president of research and product development.
