A research team from University of Leeds has figured out a way to kill cancer cells photothermally. They used Near-Infrared (NIR) to heat up gold nanotubes, and, a single-wavelength pulsed laser beam to rapidly increase the temperature near the nanotubes. This focussed, high-intensity heating kills the cancer cells.

A big advantage of the method is that NIR light has maximum penetration in the tissue without much harmful consequences. To minimize toxicity further, the gold nanotubes were coated with PSS - poly(sodium 4-styrenesulfonate).
The team is led by Steve Evans of the School of Physics and Astronomy.

Two things that have caught my attention recently.

The first concerns trapping solar energy.  One way to do this is to convert it directly into electricity with a solar panel, but one with much wider application would be to split water into oxygen and hydrogen, which can then be stored and transported.

An international team of physicists have been able to reconstruct the first ever 3-D image of individual virus particles by tweaking the X-ray diffraction technique of nanocrystallography1

Cleverly bypassing the tedious procedure of crystallizing individual particles, the researchers targeted the virus (Acanthamoeba polyphaga mimivirus) with high-energy pulses (70 fs duration) from an X-ray free electron laser. The X-rays scattered from the virus bodies, creating a 2D diffraction pattern.
Using 200 such different patterns and a mathematical algorithm to solve the problem of particle orientation, a single 3D electron density image was produced.
Sometimes science is the only witness to a crime.

Fortunately, the application of scientific evidence in criminal proceedings has grown in proportion to the availability of cutting-edge methods and technologies that can produce answers to critical questions related to guilt or innocence.

Scientific evidence, of course, is a good thing, provided that our courts do their due diligence to ensure that the testimony of expert witnesses and the observations, data, and interpretations upon which they are based are reasonably valid.
In a previous blog post, I demonstrated how to build a magnetic optical mount for a laser using Erector set parts. Here's another method of attaching a chip clip to the Erector set stand.

Parts Needed

Erector set right angle bracket 3-hole (mine is a bit more than 90°)
Erector set nut
Computer case thumbscrew
Chip Clip

I used a knife to cut a slit in the rubber grip of the chip clip just wide enough for the Erector set angle bracket to fit tightly once inserted in the grip.

I like to think of myself as a researcher who focuses on both pain and addiction. Honestly, I may never have an actual career in academic science because there is only a 1 in 5 chance of that happening. I always wanted to teach, but realize there is a slim chance of that ever happening, especially since the University system has been turned into a complete joke by administrators. That is why I like the idea of Science 2.0 and blogging because I can provide knowledge, as if teaching, in a short missive. I apologize for the recent spate of pieces, but I have been busy studying yawning in rats. That’s right Tom Coburn, yawning in rats!

Truth be told, me and my American peers were overwhelmed, overpowered, and outclassed during our first year as physics PhD students in Houston, Texas. But then we hadn't been through the intense, government sponsored “Pass the Test” coaching of our Chinese counterparts. The Chinese rip off our graduate exams, turn them in Test Drill Books, and then drill them into elite students before sending them off to US universities. Here’s an example of one of their ringer courses:

And it goes on and on:

In 2015, it doesn't need to be said for anyone over the age of 40, but for young people still newer to Miracle Vegetable and Scare Journalism claims that get pumped out in diet books, mainstream media articles and television medicine on a regular basis, here it goes: don't latch onto supplement fads.
Plagued by mental health disorders such as depression,bipolar polar disorder, and schizophrenia, are a host of artists, writers and famous people throughout history. In fact, many times the eccentric tendencies of genius are associated with mental illness.

An article in Medical Daily titled “Why Smarter People Are More Likely o Be Mentally Ill” claims over thirty studies have documented the connection, concluding:

One of the big topics in the science world is always how to make Science, Technology, Engineering and Math (STEM) more exciting.

It may not always seem like it because, let's face it, we love STEM and it's baffling that people would want to do anything else, but not everyone graduates from high school wanting to pursue it, even though they might have when they were younger.
