Vomiting machine projects better understanding of how stomach bugs spread

By - August 21, 2015 2 Pictures

Norovirus is a nasty bug that brings about inflammation in the stomach and intestines leading to pain, nausea, diarrhea and sometimes even death. It affects around 20 million people per year in the US, but despite its rampant nature, questions remain over how exactly it is transmitted. To shed further light on how one of the world's most common pathogens spreads between humans, scientists have built a vomiting machine to study its behaviour when projected into the air.

Kinsa Smart Thermometer does more than just take your temperature

By - April 30, 2013 5 Pictures
When someone is feeling sick, you take their temperature to see if they’re running a fever. That’s the way it’s been for decades. However, all that a regular thermometer will tell you is their body temperature – it won’t tell you what they might have, or what you should do. The Kinsa Smart Thermometer, while not quite a medical tricorder, is designed to do those things. Read More

X-ray device traps airborne pathogens and neutralizes them

By - February 1, 2013 1 Picture
Help may be on the way for people with compromised immune systems, severe allergies, or who otherwise have to be wary of airborne nasties. A team of scientists have created something known as a soft x-ray electrostatic precipitator, or an SXC ESP for short. It filters all manner of bacteria, allergens, viruses, and ultrafine particles from the air – plus, it kills everything it catches. Read More

DARPA produces 10 million flu vaccine doses in one month

By - January 26, 2013 4 Pictures
A familiar news topic during the flu season is the difficulties that the authorities face in producing enough flu vaccine fast enough to control the outbreak. That’s a serious enough problem, but when the influenza outbreak turns out to be the start of a global pandemic, then hundreds of millions of lives could be at risk. To combat this, the Defense Advanced Research Projects Agency (DARPA) has developed a new way of making vaccines that has turned out 10 million doses of H1N1 influenza vaccine in a month, in a recent test run.

New microscopy technique lets scientists see live viruses in their natural habitat

By - December 30, 2012 1 Picture
Traditionally, in order to view tiny biological structures such as viruses, they must first be removed from their natural habitats and frozen. While this certainly keeps them still for the microscope, it greatly limits what we can learn about them – it’s comparable to an ichthyologist only being able to study dead fish in a lab, instead of observing live ones in the ocean. Now, however, researchers at the Virginia Tech Carilion Research Institute have devised a technique for observing live viruses in a liquid environment. It could have huge implications for the development of treatments for viral infections. Read More

Crab shells used to produce cheaper pharmaceuticals

By - February 14, 2012 3 Pictures
Crabs and lobsters ... they're not just for eating, anymore. Chitin, one of the main components of their exoskeletons, has recently found use in things such as self-healing car paint, biologically-compatible transistors, flu virus filters, and a possible replacement for plastic. Now, something else can be added to that list. Researchers from the Vienna University of Technology are developing a technique in which chitin is being used to cheaply produce a currently very-expensive source of antiviral drugs. Read More

Scientists enlist viruses to help build biomaterials

By - October 24, 2011 3 Pictures
It’s one of those enduring mysteries of nature – how can one biological substance end up becoming several different types of material? One example is collagen, a fibrous protein that can be made into body parts such as corneal tissue, cartilage, bone, and skin. In an effort to better understand such processes, scientists at the University of California at Berkeley decided to see if they could manipulate another biological building block into forming itself into different materials. They succeeded, using viruses known as M13 phages. Read More

Plastic antibodies effective in living animals

By - June 14, 2010 2 Pictures
From bricks to jackets, it seems just about anything can be made using plastic nowadays. The latest items to get a plastic fantastic makeover are antibodies – proteins produced by the body’s immune system to recognize and fight infections from foreign substances. Scientists are reporting the first evidence that a plastic antibody works in the bloodstream of a living animal, opening up the possibility of plastic antibodies being custom tailored to fight everything from viruses and bacteria to the proteins that cause allergic reactions.
