(Phys.org)—A team of researchers with the European Academy of Bozen (EURAC) aka, the Institute for Mummies and the Iceman in Bolzano, Italy, has found examples of the oldest known samples of red blood cells. In their paper uploaded to the open access site, Journal of the Royal Society Interface, the team explains how they found the red blood cells and why they now believe the Iceman died very quickly.

Introduction We have endeavored to develop a means by which eye gaze can be detected. This goal was achieved using the same principles learned in Lab4, where we recorded the motor speed of a small hub fan using the combination of IR emitter plus phototransistor, henceforth referred to as an emitter-phototransistor pair. High Level DesignSeveral […]

Introduction We present to you, the ultimate guitar — no strings attached (literally)! This guitar features an infrared strumming system and a fret board with physical buttons. It sounds like a real acoustic guitar and it works like a real acoustic guitar, but in the world of Guitar Blocks, it is your ultimate weapon in […]

Introduction The goal of this project was to assist the user in learning the proper technique for a physical exercise, in our case a dumbbell bicep curl. As our understanding of biology and anatomy improves, the design of physical exercises is improved by the application of scientific principals and experimental results. For each exercise there […]

Based on a comprehensive life cycle analysis comparing the environmental impacts and economic outcomes for managing manure and food waste produced on a dairy farm, researchers found that anaerobic co-digestion of the waste products had substantial cost, energy, and environmental benefits compared to digestion of manure but disposal of food waste in a landfill.

Researchers from North Carolina State University and China’s Suzhou Institute of Nano-Science and Nano-Biotics have developed an inexpensive technique called “microcombing” to align carbon nanotubes (CNTs), which can be used to create large, pure CNT films that are stronger than any previous such films. The technique also improves the electrical conductivity that makes these films attractive for use in electronic and aerospace applications.

Introduction The purpose of this project was to design and implement a debugger for the ATmega644 that communicated through its JTAG interface and was capable of controlling program execution by setting breakpoints and accessing registers and memory. We have three main objectives in this report: To enable a user to properly download our code onto […]

Introduction The ultrasonic haptic vision system enables a person to navigate hallways and around large objects without sight, through the use of an ultrasonic rangefinder that haptically interfaces with the user via tiny vibrating motors mounted on the users head.  The idea behind this project was to construct a sixth sensory system that interacts with […]

A group of Cambridge computer scientists have set a new gold standard for openness and reproducibility in research by sharing the more than 200GB of data and 20,000 lines of code behind their latest results – an unprecedented degree of openness in a peer-reviewed publication. The researchers hope that this new gold standard will be adopted by other fields, increasing the reliability of research results, especially for work which is publicly funded.

Idea Build a cheap and simple full software controlled step-up (boost) converter to drive a LED string of 10 LEDs. LEDs are used as string to light up a acrylic engraved plate placed in a holder (also made out 5 layers of lasered black acrylic glas). Step up is from 5V to about 30V, current […]
