Manure from dairy cows, which is commonly used as a farm soil fertilizer, contains a surprising number of newly identified antibiotic resistance genes from the cows’ gut bacteria. The findings, reported in mBio the online open-access journal of the American Society for Microbiology, hints that cow manure is a potential source of new types of antibiotic resistance genes that transfer to bacteria in the soils where food is grown.

Before working as an applications engineer, I worked as an IC test development engineer here at TI. One of my projects was to characterize an I2C temperature sensor. After writing some software, I threw together a hand-wired prototype board. I was in a hurry, so I left off that pesky decoupling capacitor. Who needs it, […]

(Phys.org) —Google Trends has added a new service to its mix, where users can enter email subscriptions for Google Trends, and as a can be sent notifications on topics of interest, showing them what is popular around the web now and in the past.

Description The LT3690 is an adjustable frequency monolithic buck switching regulator that accepts input voltages up to 36V. A high efficiency 90mΩ switch is included on the device along with the boost diode and the necessary oscillator, control, and logic circuitry. The internal synchronous power switch of 30mΩ increases efficiency and eliminates the need for […]

ITEAD studio is based in Shenzhen, China, which is located with China’s biggest electronics market as well as one of the most integrated electronic supply chains in the world. A vast number of exciting and innovative products are designed, sourced and manufactured around us every day. In electronics the big picture is usually more compelling […]

(Phys.org) —The ability to stick objects to a wide range of surfaces such as drywall, wood, metal and glass with a single adhesive has been the elusive goal of many research teams across the world, but now a team of University of Massachusetts Amherst inventors describe a new, more versatile version of their invention, Geckskin, that can adhere strongly to a wider range of surfaces, yet releases easily, like a gecko’s feet.

Lattice Semi has released their iCEstick eval board.This board has a high-performance, low-power iCE40HX1K FPGA on board and has a USB thumb drive form factor. IO connectors include 16 LVCMOS/LVTTL (3.3 V) digital I/O connections on 0.1” through-hole connections and a 2 x 6 position Digilent Pmod connector for other peripheral connections. The board’s FTDI […]

Suddenly there was a word for chili peppers. Information about archaeological remains of ancient chili peppers in Mexico along with a study of the appearance of words for chili peppers in ancient dialects helped researchers to understand where jalapeños were domesticated and highlight the value of multi-proxy data analysis

(Phys.org) —SRI International, a research center that conducts client-sponsored research and development for government and other organizations, is attracting attention for work on what micro-factories might accomplish in the future, with micro-robots coordinated to go to work building products. SRI’s ant-like microrobots in large numbers can reliably handle solid and liquid materials, including electronics

Hardware/software combo can create professional schematics from undocumented PCBsFairport, NY. The RevEng System is a remarkable reverse-engineering hardware tool for creating professional quality circuit schematic diagrams from a sample PCB that lacks documentation. The RevEng System consists of a PC-controlled continuity-detecting hardware system, RevWin control software, and EdWin, a fully featured CAD package. RevEng ʽlearnsʼ […]
