4:24 PM | Distillations Podcast: Life with HIV: Success without a Cure?
Thirty years ago an HIV diagnosis was a death sentence. Today, sophisticated drug cocktails known as highly active antiretroviral therapy, or HAART, have dramatically changed the fates of people with the disease.  Yet in many ways we’re treading water: each year the U.S. sees around 50,000 new HIV cases, and estimates show that 20-25% of these people don’t know they’re infected. And, while the drugs are effective, many people throughout the world can’t afford […]

10:15 AM | A nanoelectromechanosensing approach to detect cancerous transformation of single cells
Since diseased cells, such as cancer cells, frequently carry information that distinguishes them from normal cells, accurate probing of these cells is critical for early detection of a disease. Adding to these highly accurate methods for monitoring such alterations in single cells, researchers have now demonstrated a nanoelectromechanical procedure to relate the correlation between the mechanical stimulation of a cell's actin filaments and the electrical activities of ion channels to the […]

9:56 AM | Discovery opens door for radical reduction in energy consumed by digital devices
A new paper describes the first direct observation of a long-hypothesized but elusive phenomenon called 'negative capacitance'. The work describes a unique reaction of electrical charge to applied voltage in a ferroelectric material that could open the door to a radical reduction in the power consumed by transistors and the devices containing them.

9:44 AM | Pyramid nanoscale antennas beam light up and down
The new antennas look like pyramids, rather than the more commonly used straight pillars. The pyramid shape enhances the interference between the magnetic and electric fields of light. This makes the pyramid-shaped antenna capable of enhancing light emission and beaming different colours of light towards opposite directions.

7:50 PM | The Chemistry of Mulled Wine
There are few things more warming than a mug of mulled wine in the depths of December. Exact recipes may vary, but they all include a common core of ingredients, each of which contributes something to the final flavour. This graphic examines some of the key chemicals that each ingredient adds into the mix, with […]

7:39 PM | Anyone heard of paying chemists by the reaction?
The different ways to pay chemists:1. A yearly salary2. An hourly wage3. By project (i.e. deliver4. Subsistence wages, suppletmented with food and alcohol (kidding)Has anyone heard of paying people by the reaction? If so, how did it work out for you? How much did you get paid?Seems to me that this is a bad deal for any chemist. (How do you determine how you get paid? Do you have to work up the reaction, or just set it up? How many stir plates do you get?) Surely there is some kind of labor law […]

5:16 PM | About that Night I Spent in Jail...
Ah yes, Christmas break in 1983. I remember it well. But the story starts well before that.Some 17,000 years ago when the glaciers retreated from Minnesota for good, they had scrapped the Canadian Shield pretty thoroughly, leaving a tremendous number of lakes in the Northeastern part of Minnesota and also the Southwestern parts of Ontario. The Ojibway discovered that the area was fabulous for canoeing. Since the distances between lakes were short it was easy to carry canoes and such between […]

What do you need if you want to create an art piece that is not visible to our bare eyes? For ages, visual artists have invented tools for manipulating various materials to shape their reflections of the world into art pieces that we can appreciate with our eyes: paintings, sculptures, and installations arts. Sometimes it […]

11:55 AM | What is Isopropyl Alcohol?
Isopropyl alcohol is the simplest secondary alcohol, in which the carbon in the alcohol group is attached to two methyl groups. The chemical formula is sometimes described as (CH3)2CHOH to indicate this structure (the formula can be simplified to C3H8O or C3H7OH). This isomer of propanol forms a colourless and flammable solution with a strong [...]

11:39 AM | The demise of SciAmBlogs
So I hear that SciAmBlogs is undergoing a radical overhaul and shedding no less than half of its bloggers, many of whom have been with the network since its inception. This includes many whose thought-provoking writings I respect - even though I don't always agree with them - like Janet Stemwedel and Eric Michael Johnson.It's a shame really, because I think the network had really distinguished itself as one of the few blogging networks in the world whose bloggers had vibrant, independent voices […]

10:32 AM | How the insurance market perceives nanotechnology risks
Insurance companies are major stakeholders capable of contributing to the safer and more sustainable development of nanotechnologies and nanomaterials. This is owed to the fact that the insurance industry is one of the bearers of potential losses that can arise from the production and use of nanomaterials and nanotechnology applications. Researchers have examined how the insurance market perception of nanotechnology can influence the sustainability of technological advances and insurers? […]
