News: Starve E Coli of Copper to Cure Aggressive UTIs

Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.

News: How Calcium Sets Off a C Diff Infection

Unfortunately, the very places we go to receive health care put us at risk for becoming infected with superbugs, bacteria exposed to so many antibiotics that they have become immune to their effects. Clostridium difficile (C. diff) is one such bacteria. It causes inflammation of the colon and rampant diarrhea that can have life-threatening consequences. Part of its virulence lies in the tough spores formed by the bacteria. They are responsible for starting infections in the colon and for spre...

News: A Bacteria Could Stop Citrus Greening Disease from Killing Orange Trees

Citrus greening disease — caused by a bacteria spread by psyllid insects — is threatening to wipe out Florida's citrus crop. Researchers have identified a small protein found in a second bacteria living in the insects that helps bacteria causing citrus greening disease survive and spread. They believe the discovery could result in a spray that could potentially help save the trees from the bacterial invasion.

News: Step Aside Penicillin — A Deep Dive into Fungus Genes Reveals Over 1,300 Potential Antibiotics Waiting to Be Discovered

On October 17, 1943, a story in the New York Herald Tribune read "Many laymen — husbands, wives, parents, brothers, sisters, friends — beg Dr. Keefer for penicillin," according to the American Chemical Society.

News: Compound in a Frog's Defensive Slime May Treat Your Next Flu Infection

Our quest to find novel compounds in nature that we can use against human diseases —a process called bioprospecting — has led a research team to a small frog found in India. From the skin slime of the colorful Hydrophylax bahuvistara, researchers reported finding a peptide — a small piece of protein — that can destroy many strains of human flu and can even protect mice against the flu.

News: 14 Types of Bacteria & 10 Strains of Fungus Are Responsible for All the Delicious Flavors of Cheese

If you want to appreciate the value of microbes, look no further than a chunk of cheese. Because cheese roughly traces back to the Neolithic Era, we might say the earliest cheesemakers were the first humans to manipulate microbes—without even knowing it. Now, thanks to microbiologists and the long tradition of cheesemaking, we know a lot more about the microbes that make our favorite types of cheese possible.

How To: Dox Anyone

Doxing is the act of finding one's personal information through research and discovery, with little to no information to start with. You may have seen doxing in the news, for instance when not so long ago, hacker team Anonymous doxed and reported thousands of twitter accounts related to ISIS.

The tutorial I will provide to you now will teach you the basics of doxing and how you can prot...

How To: Identify Web Application Firewalls with Wafw00f & Nmap

Web application firewalls are one of the strongest defenses a web app has, but they can be vulnerable if the firewall version used is known to an attacker. Understanding which firewall a target is using can be the first step to a hacker discovering how to get past it — and what defenses are in place on a target. And the tools Wafw00f and Nmap make fingerprinting firewalls easy.
