The Future of Molecular Electronics

MEimg

The emerging field of molecular electronics could take our definition of portable to the next level, enabling the construction of tiny circuits from molecular components. In these highly efficient devices, individual molecules would take on the roles currently played by comparatively-bulky wires, resistors and transistors. Read More →

When many people find stories reporting scientific research in animals, they typically assume that the content will somehow involve some aspect of genetic modification. Typically this is true, and generally these modifications are accompanied by heated ethical debates. Canadian researchers, however, have been looking into a completely different and promising technology that I thought I’d share with you today. Read More →

Evolution of Asteroid Study

Asteroid

On 13 April 2029, asteroid 99942 (heretofore known as Apophis) is estimated to come within 18,300 miles of the Earth. This alarming distance is even more shocking when one takes into consideration that modern geosynchronous satellites orbit the Earth at approximately 26,000 miles. Once the shock has cleared, there is another fact you need to take into consideration: astronomers across the globe are tracking Apophis every day. It is currently labeled as a “0” on the Torino Scale. The Torino Scale is used to categorize the likeness of an asteroid impact on Earth. Read More →

To See or Not to See

Motor-Neurons

The brain is a complicated network of small units called neurons, all working to carry information from the outside world, create an internal model, and generate a response. Neurons sense a signal through branching dendrites, carry this signal to the cell body, and send it onwards through a long axon to signal the next neuron. However, neurons can function in many different ways; some of which researchers are still exploring. Read More →

On Digital and Analog Signals

Signals

Have you ever wondered why some people claim that music stored on vinyl discs sounds so much better?  Is digital music really worse than analog?  There are many differences between the two mediums- the heart of the distinction lies in the difference between digital (discrete) and analog (continuous) data.

Could Water Be Used to Charge a Cell Phone?

Research 2014

A research team from Massachusetts Institute of Technology (MIT) recently found that water droplets can generate an electric charge when repelled from a superhydrophobic (ultra-waterproofed) metal surface. This technology may be used to develop portable devices that can harness the humidity from surrounding air, converting it into enough electricity to charge battery-powered electronics like cell phones.

Alan Turing led a team of code breakers at Bletchley Park which cracked the German Enigma machine cypher during WWII – but that is far from being his only legacy. Read More →

Could Your Child Kill?

I’m currently taking a course focused on criminological theory and as I’ve been thinking through the theories, I’ve tried to better understand all of the things that can go wrong in a person that causes him/her to take the life of another. More specifically, how can this happen in the case of a child? Read More →

Atoms, Ions and Molecules. What’s the Difference?

atom_img1

When you view an atom, the first question you might ask is ‘what kind of atom is it?’ What you are really asking is ‘which element am I looking at?’ You can answer this by counting the number of protons in the atom. The number of protons, neutrons and electrons is the same in a neutral atom- that is, an atom with no charge. So, in a regular Calcium atom, there are 20 protons, 20 neutrons and 20 electrons. The electrons orbit around the nucleus and have a negative charge.  An isotope is a version of the element with a different number of neutrons. Read More →

Picotechnology: Beyond Nano-Scale Engineering

picotech

While it’s become quite popular to discuss nanotechnology for a number of years now, picotechnology is the science of the future. This type of engineering is on a scale three orders of magnitude smaller than that which nanotechnology deals with. It’s actually considerably smaller than most chemistry measurements. Read More →
