The Physical Limit of Moore’s Law

In 1965 a chemist named Hail Gordon Moore famously predicted that the number of transistors per square inch on integrated circuits would double every two year.

Originally, he assumed it would only last a decade or so. But technology advances have kept pace with what has become known as Moore’s Law ever since.

However, we are approaching the physical limit of Moore’s Law. Read about potential new advances, or the end of increased computing power over at Nature.

Celebrating 25 Years of Hubble Images

This year Hubble telescope celebrates 25 years of images, many of which have fundamentally altered our understanding of the universe.

It is responsible for the Hubble Deep Field (a tiny dark spot in the sky that has ~3,000 galaxies) and our current estimate of the age of the universe 13.8.

To celebrate, here are some stunning images from the past 25 years of glorious space exploration. 6405926-3x2-700x467 6405858-3x2-700x467 6406044-3x2-700x467 6406110-3x2-700x467 6406190-3x2-700x467 6406222-3x2-700x467 6405962-3x2-700x467 6406004-3x2-700x467 6406032-3x2-700x467 6406144-3x2-700x467

Help Solve the Mystery of the Disappearing PhD

Very VERY few of those who pursue a PhD in science will continue on to a tenure track position. We’ve spoken a lot on this blog about postdocs, faculty positions, and what industry might look like.

From Science:

Now Melanie Sinche of theLabor and Worklife Program at Harvard Law School is trying to learn more. “If you earned a PhD in any of the physical, life, computational, engineering, or social sciences between 2004 and 2014 and have ever worked, trained, or studied in the U.S.,” you can help by participating in a confidential online survey estimated to take about 15 minutes.

U.S. Atom Smasher has its Swan Song

The U.S. atom smasher (which is a phenomenal nickname for a particle collider facility) has made a new discovery concerning the Higgs boson particle!

Sadly, the facility (actually named the Tevatron collider) in Batavia, Illinois was shut down in 2011. So this important paper is a little too late. Read more about what they found over at Science news.sn-ataomsmasherH

Don’t Trust Your Data

Or more specifically, don’t always trust your own data analysis skills.

As a PhD student soon to be on the Postdoc market I am eagerly learning all I can about bioinformatics and coding. Additionally, I really like it.

So reading this review of the new book by  Vince Buffalo Bioinformatics Data Skills is both awesome and informative. I’ve already added it to my Amazon wish list.

Literature does not mean “big pile of facts”

As scientist we tend to take what has been done before at face value. If a publication demonstrates a result, it is often tucked away into a mental file: or “big pile of scientific facts”.

While Stephen Heard doesn’t advocate repeating all experiments, he does note that this may not always be the case. For example:

“Published research findings are sometimes refuted by subsequent evidence, with ensuing confusion and disappointment.”
