Many Dimensions to 3D Printing Adoption

As part of Machine Design’s 90th anniversary issue in January, we’ve asked industry experts to take a look at the present and future of technology and how it will impact the design and operation of manufacturing over the next decade. Q: How is 3D printing addressing the challenges design engineers face? Benning: 3D printing is pioneering a new wave of design capabilities for design engineers who can now create durable prototypes and end-use production parts. 3D is about more than…

Fingerprint Recognition for the Car: Use Cases and Design Considerations

Fingerprint recognition has become a popular feature of many smartphones, providing a convenient and trusted method for unlocking the device and for authenticating payments and passwords. In general, a fingerprint sensor delivers a faster and more secure alternative to other device-unlock security measures such as PINs, passwords, or patterns entered on a virtual keypad, which can easily be observed and copied. No matter which authentication scheme is used, it’s likely that at some point users will experience unlock problems. The…

Grain traits traced to ‘dark matter’ of rice genome — ScienceDaily

Domesticated rice has fatter seed grains with higher starch content than its wild rice relatives — the result of many generations of preferential seed sorting and sowing. But even though rice was the first crop to be fully sequenced, scientists have only documented a few of the genetic changes that made rice into a staple food for more than half the world’s population. New research now finds that a sizeable amount of domestication-related changes in rice reflects selection on traits…

Climate Change and Attitude Change

Engineering Ethics Blog: Climate Change and Attitude Change skip to main | skip to sidebar Pages Climate Change and Attitude Change The old joke about how an optimist and a pessimist can see the same glass of water and say different things about it applies to a lot of things.  The optimist who says it’s half full brings a different attitude to the same physical facts that the half-empty pessimist looks at, but draws different conclusions from them.  Climate change…

NASA’s treasure map for water ice on Mars — ScienceDaily

NASA has big plans for returning astronauts to the Moon in 2024, a stepping stone on the path to sending humans to Mars. But where should the first people on the Red Planet land? A new paper published in Geophysical Research Letters will help by providing a map of water ice believed to be as little as an inch (2.5 centimeters) below the surface. Water ice will be a key consideration for any potential landing site. With little room to…

What keeps cells in shape? New research points to two types of motion — ScienceDaily

The health of cells is maintained, in part, by two types of movement of their nucleoli, a team of scientists has found. This dual motion within surrounding fluid, it reports, adds to our understanding of what contributes to healthy cellular function and points to how its disruption could affect human health. “Nucleolar malfunction can lead to disease, including cancer,” explains Alexandra Zidovska, an assistant professor in New York University’s Department of Physics and the senior author of the study, which…

Scientists design new grid batteries for renewable energy — ScienceDaily

How do you store renewable energy so it’s there when you need it, even when the sun isn’t shining or the wind isn’t blowing? Giant batteries designed for the electrical grid — called flow batteries, which store electricity in tanks of liquid electrolyte — could be the answer, but so far utilities have yet to find a cost-effective battery that can reliably power thousands of homes throughout a lifecycle of 10 to 20 years. Now, a battery membrane technology developed…

Ice on lunar south pole may have more than one source — ScienceDaily

The discovery of ice deposits in craters scattered across the Moon’s south pole has helped to renew interest in exploring the lunar surface, but no one is sure exactly when or how that ice got there. A new study published in the journal Icarus suggests that while a majority of those deposits are likely billions of years old, some may be much more recent. Ariel Deutsch, a graduate student in Brown University’s Department of Earth, Environmental and Planetary Sciences and…

Nobel Prize in Chemistry 2019: Lithium-ion batteries — ScienceDaily

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2019 to John B. Goodenough, of The University of Texas at Austin, USA, M. Stanley Whittingham, of Binghamton University, State University of New York, USA, and Akira Yoshino of Asahi Kasei Corporation, Tokyo, Japan, and Meijo University, Nagoya, Japan “for the development of lithium-ion batteries.” They created a rechargeable world The Nobel Prize in Chemistry 2019 rewards the development of the lithium-ion battery. This lightweight,…

Research compared effects of fresh and thermally processed oil — ScienceDaily

Foods fried in vegetable oil are popular worldwide, but research about the health effects of this cooking technique has been largely inconclusive and focused on healthy people. For the first time, UMass Amherst food scientists set out to examine the impact of frying oil consumption on inflammatory bowel disease (IBD) and colon cancer, using animal models. In their paper published Aug. 23 in Cancer Prevention Research, lead author and Ph.D. student Jianan Zhang, associate professor Guodong Zhang, and professor and…
