News: How Parental Choice Not to Vaccinate Kids Starts and Spreads Pertussis Outbreaks

It's not always easy to get to the root of an infection outbreak. Epidemiologists study infected people, contacts, and carefully examine where the infections happened and when. In the case of a 2012 outbreak of pertussis — whooping cough — in Oregon, scientists just published an analysis of how vaccination status affected when a child became infected during the outbreak.

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: A Common Cancer-Causing Mono Virus Has a Special Trick to Hide from the Body's Defenses

Most of us have already had an encounter with the Epstein-Barr virus, or EBV, for short. As part of the herpes family, it's one of the most common disease-causing viruses in humans. We get the disease with (or without) some nasty symptoms, then we recover. However, EBV stays in our body after the illness has ended, and it's one of the few viruses known to cause cancer.

News: 4 Billion Year Old 'Fossil' Genes May Be Our Secret Weapon Against Infection

The evolution of our infection-fighting systems may have something to teach modern scientists. That's what a group from the University of Granada in Spain found when they studied a protein that's been around for over four billion years. Their work, by senior author José Sánchez-Ruiz and colleagues in the Department of Physical Chemistry, was published in the journal Cell Reports.

News: Living Bacteria in Clothing Could Detect When You Come in Contact with Pathogens or Dangerous Chemicals

While at work, you notice your gloves changing color, and you know immediately that you've come in contact with dangerous chemicals. Bandages on a patient signal the presence of unseen, drug-resistant microbes. These are ideas that might have once seemed futuristic but are becoming a reality as researchers move forward with technology to use living bacteria in cloth to detect pathogens, pollutants, and particulates that endanger our lives.

News: Taking Genetic Scissors to Infected Cells Could Cure HIV

Being infected with HIV means a lifetime of antiviral therapy. We can control the infection with those drugs, but we haven't been able to cure people by ridding the body completely of the virus. But thanks to a new study published in Molecular Therapy by scientists at the Lewis Katz School of Medicine (LKSOM) at Temple University and the University of Pittsburgh, all that may change.

News: Scientists Discover How to Track Down HIV's Hiding Spots—A Potential Pathway to a Cure

Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.

How To: Six Things You're Definitely Doing Wrong in the Restroom—As Proven by Science

Avoiding discussion on the subject has led many of us to unwittingly interact incorrectly during our private time with our old friend, Jon.

How To: Produce a 3D house/building model using Maya

Autodesk Maya, affectionately known as just Maya to its users, is a 3D computer graphics software that makes it easy to create impressive, realistic models of real-life - or imagined - objects. Super useful for graphic designers, film makers and web designers, the program is one that you should study if you're looking to go into one of the fields above.

How To: Identify and control the pine tip moth

This is a tutorial for controlling the Pine tip moth. Identifying and controlling the pine tip moth consists of studying the small plants of pine. The attacks on pine trees is caused by Nantucket pine tree moth found along the Rio Grande Valley as far north as Espanola, it has spread to South Arizona and California by importing grafts from Mexico. The moths are 3/8 inch long reddish brown to grey in color. They attack the main stem of the baby plant and the pines instead of growing vertical g...

How To: Do remote viewing and learn how it works

Excerpts from a presentation by Dr. Simeon Hein at the International UFO Congress, 2005. Dr. Hein is the director of the Institute for Resonance in Boulder, Colorado. The Institute is devoted to the study of subtle-energy sciences including remote viewing, crop circles and related subjects. Dr. Hein has a Ph.D. in sociology and has previously taught research methodology and statistic courses. Dr. Hein first learned remote viewing in 1996 and subsequently became involved in crop circle researc...

How To: Manage high blood pressure through diet

Sometimes pills aren't the best answer. Doctors do not need to prescribe medications for common health problems, such as high blood pressure. They can be helped by simple adjusting your lifestyle. If you have high blood pressure, you are more than twice as likely to develop heart disease and six times more likely to have a stroke than people with normal blood pressure. Manage your condition through diet.
