It appears as though the world of science has been conspiring to keep me from fulfilling your need for continual updates into current news stories, but I have fought against all odds to make it back to you with a new post. My apologies for the delay since my last piece – I’ve been making big strides in my own work, spending long hours in the lab, yada yada yada. The important thing is I’m back now, and your cravings may be satiated. Let’s get on with it….
When it comes to diamonds, obviously bigger is better. Unless of course, you are my wife, in which case I hope simple, elegant beauty will suffice for now.

They are highly resilient little bugs that rapidly acquire antibiotic resistance, thus causing tremendous problems in hospitals throughout.
As you no doubt have heard, antibiotic resistance is a major hurdle that the field is working to tackle. Luckily, we have work being done like this recent study published in PLoS Pathogens that aims to combat this bug head on. It seems we may have a powerful new antibiotic that targets the bacteria’s ability to….recycle. Continue reading →
