Magnetic hard drives go atomic
Physicists demonstrate the first single-atom magnetic storage.

Chop a magnet in two, and it becomes two smaller magnets. Slice again to make four. But the smaller magnets get, the more unstable they become; their magnetic fields tend to flip polarity from one moment to the next. Now, however, physicists have managed to create a stable magnet from a single atom.

The team, who published their work in Nature on 8 March1, used their single-atom magnets to make an atomic hard drive. The rewritable device, made from 2 such magnets, is able to store just 2 bits of data, but scaled-up systems could increase hard-drive storage density by 1,000 times, says Fabian Natterer, a physicist at the Swiss Federal Institute of Technology (EPFL) in Lausanne, and author of the paper.

“It’s a landmark achievement,” says Sander Otte, a physicist at Delft University of Technology in the Netherlands. “Finally, magnetic stability has been demonstrated undeniably in a single atom.”

The Whoosh bottle: Ethanol combustion in a bottle

I would explain the science behind it but you really just put some ethanol in a large polycarbonate bottle which is ignited and it goes: “Whooooshh!” and that’s why it’s called a whoosh bottle. The combustion reaction is as follows :

  • C2H5OH + 3O2 –> 2CO2 + 3H2O

It’s suposed to demonstrate the rapid combustion of alcohols but all i can think about is that they named it after the sound it makes. Whooosh!!!

-”Hey Kathy, you have a PhD in chemistry right?… Show us an experiment.”

-”Ok now guys, this one is called the Whoosh bootle!…”

Breaking The Supposed Limit In Seeing The Microscopic World Earns Three Chemistry Nobel

by Michael Keller

Three researchers were awarded the 2014 Nobel Prize in Chemistry today for breaking through what was thought to be an absolute optical limit in seeing microscopic objects like viruses and molecules.

The Nobel committee responsible for deciding the winners chose to honor the separate work of two Americans, Eric Betzig and William Moerner, and German Stefan Hell. These scientists pioneered what is called super-resolved fluorescence microscopy, which has opened up a whole new frontier for understanding how life works at the nanoscale. (Txchnologist has previously featured more of Betzig’s groundbreaking work here.)

“I was sitting in my office when the call from Stockholm reached me,” said Hell, who is the director of the Max Planck Institute for Biophysical Chemistry. “I am enormously gratified that my work and that of my colleagues has received the highest distinction for scientific research."  

Their innovations, using light to excite molecules that have been tagged with fluorescent markers, are now being used around the world. They are letting researchers use visible light to glimpse separate objects that are closer together than what was thought to be the limit of 0.2 microns.  This minimum is called the Abbe diffraction limit, which is half the length of the wavelength of the light used to see something through a microscope.

Construction Going Green With Asphalt And Concrete

by Katharine Gammon, Inside Science

Construction and maintenance of roads and buildings use up lots of money and resources. Asphalt roads wear out over time, and acquiring concrete for buildings means digging deeper and deeper into quarries for material. But new recycling technologies may take some of the pressure off the world’s resources while keeping roads paved and buildings safe.

Asphalt is a paving material made of gravel and other materials bound together with a thick petroleum. Over time, exposure to the elements causes asphalt to age, become brittle and crack. This means that roads paved with asphalt must be repaved periodically. As the old asphalt is pulled up, only a tiny fraction can be reused: most of it heads to a landfill or gets stacked up for later use.

大さん橋の突端にはためくUW flagが

Hey anon I’ve got a question for you.

In 2012 I graduated from BCIT (a well respected technical institute in BC) in a chemistry program. I got good grades, I even scored a research assistant summer job.

But after I graduated I could not find long term employment in my field or anywhere else.

Was I not trying hard enough? Did I deserve to spend years of my life educating myself and job searching for nothing?

I spent 1.5 years applying for hundreds of jobs. I got dozens of job interviews. I applied for everything from lab technicians to grocery clerks. In the end the only jobs I got were temporary and I ended up driving myself further into debt just to stay in the city and continue job searching. I was living in the third largest city in Canada and spent every single day looking for work or job experience.

Eventually I ran out of money and had to move back home with my parents. But even from there I continued job searching.

I finally had to give up on the idea of looking for work and was forced to head back to university (even though I can’t afford it). I’m not optimistic that the job market will be any better when I graduate, and I fully expect to have $50K in debt on top of the fragile economic situation that faces many young people and recent graduates.
