Imaging dynamics of small biomolecules inside live cells
Posted on: 02 Mar 2014
Researchers at Columbia University have made a significant step toward visualizing small biomolecules inside living biological systems with minimum disturbance, a longstanding goal in the scientific community. In a study published March 2nd in Nature Methods, Assistant Professor of Chemistry Wei Min’s research team has developed a general method to image a broad spectrum of small biomolecules, such as small molecular drugs and nucleic acids, amino acids, lipids for determining where they are localized and how they function inside cells.
Your Image on an Arduino! – TFT LCD Screen Guide
Posted on: 02 Mar 2014
Have you ever heard of TFT LCD screens? They are great ways to display information from your Arduino, or display pictures. The Arduino team just released an official TFT LCD screen with their new Robot at Maker Faire 2013. It’s very easy to get started with!! This tutorial will show you how to get the […]
DIY portable LED strobe
Posted on: 01 Mar 2014
I and my friends like to have fun in summer. We like to fool around with music when we are camping. To make those parties more likely to professional ones I have made portable 9V LED strobe. For my surprise it really gives a big effect. I hope you will like it! Here is the […]
Interfacing the DAC7564 to an MSP430
Posted on: 28 Feb 2014
In this article I’ll try to show how to use an MSP430 with a DAC7564. This is probably the first from a series of articles showing different devices I plan to use in a project. The DAC7564 The DAC7564 is a low-power, voltage-output, four-channel, 12-bit digital-to-analog converter (DAC). The device includes a 2.5V, 2ppm/°C internal […]
Measuring microamps & milliamps at 3 MHz bandwidth
Posted on: 27 Feb 2014
Recently I needed to actually “see” a current waveform in the 100 uA to 5 mA range with at least a couple MHz bandwidth. This extremely expensive probe would have been perfect, but instead I built something similar for about $30 using the amazing Analog Devices AD8428 amplifier. Click “Read more” for details and a […]
SD Card Breakout for Breadboards
Posted on: 26 Feb 2014
This weeks PAW is just a breakout board for micro SD cards. There’s a number of boards like this on the market already, but they are kinda expensive and I like doing my own stuff, so here it is… 🙂 The board have a LDO that supplies the SD card with 3.3 volts and there […]
Six LED challenges that still remain
Posted on: 25 Feb 2014
While LED based solid-state lighting continues to gain ground, and several major challenges have been solved, some still remain. Energy savings and the savings that a long product lifetime brings certainly have spurred adoption in a long list of applications. Cities, sports facilities, retail, medical, residential and industrial use, are all on the rise. The […]
Optic lens developed for Hard X-ray Nanoprobe beamline achieves 11-nm focus
Posted on: 24 Feb 2014
At the National Synchrotron Light Source II (NSLS-II), now under construction at Brookhaven National Laboratory, the Hard X-ray Nanoprobe beamline (HXN) will enable scientists to image structures at ever-smaller spatial scales. HXN’s long-range goal is to achieve a resolution of 1 nanometer (nm), or a billionth of a meter, completely eliminating the long-standing resolution gap between x-ray and electron microscopes
Journey to the center of the universe
Posted on: 24 Feb 2014
I had the fortune to visit CERN (European Council for Nuclear Research) earlier this month. Located on the Franco-Swiss border, CERN is home to the most powerful particle accelerator mankind has ever built, the Large Hadron Collider, otherwise known as the LHC. Here, bunches of approximately 100 billion protons each are accelerated in opposing directions […]
Key protein discovered as essential for malaria parasite transmission to mosquitos
Posted on: 23 Feb 2014
Scientists studying the sexual transformation of the malaria parasite have solved a long-standing mystery in parasite biology. Two research teams have independently discovered that a single protein acts as the master genetic switch that triggers the development of male and female sexual forms of the malaria parasite.
