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: Bacteria Turned into Factories, Supplying Critical Enzymes to Make Cancer Drugs Cheaper & Save Endangered Yew Trees

Cytochrome P450 (P450s) are proteins found in nearly all living organisms, which play roles that range from producing essential compounds and hormones to metabolizing drugs and toxins. We use some of the compounds synthesized by P450 in plants as medical treatments, but the slow growth and limited supply of these plants have put the drugs' availability in jeopardy and jacked up prices.

News: Watch Out Amateur Mushroom Hunters — Death Caps Are Nothing to Mess With

There is a reason the Amanita phalloides mushroom is called the "Death Cap." It can kill you. Mushrooms are a type of fungi, an organism that produces thread-like mycelia that often produce spores. Spores allow the fungi to reproduce. Molds, lichens, and yeast are all fungi, but the most visible fungi are mushrooms. Some fungi are delicious, but others can cause disease or, and still others, like Penicillium, can cure it.

News: Say Goodbye to Almonds—Common Pesticide Additive in Orchards Linked to Honey Bee Colony Collapse

The search for the causative agent of colony collapse—the mass die off of honey bees throughout the US and Europe—has escalated with increasing confusion lately. Everything from pesticides and stress to viruses and mites have been implicated, and some researchers think that many of these environmental factors work together to take down hives.

News: How Researchers Could Use Bacteria to Determine Time of Death

When a dead body is discovered, finding out when the person died is just as important as finding out how the person died. Determining the time of death has always involved lots of complicated scientific detective work and less-than-reliable methods. However, a study by Nathan H. Lents, a molecular biologist at the John Jay College of Criminal Justice in New York, is the first of its kind to show how microbes colonize a body's ears and nose after death.
