Cancer Diagnosis Through Breath Tests

Not only can a breath test tell you how much you’ve had to drink, now it can tell you if you have cancer! Ok, not exactly the same thing, but it’s pretty interesting what your breath can tell. Medical News Today details:

US scientists have developed and tested a prototype breath test to detect lung cancer

The results of the test is published in the international journal of respiratory medicine Thorax.

In tests, the colour testing device, which is about the size of a coin and is not expensive, had a 75 per cent success rate in detecting people with cancer.

It can also detect people with early stages of lung cancer.

However, in testing the device also showed false positives – it picked out people without lung cancer.

Using a technique called a “colorimetric sensor array”, the test picks up the chemical fingerprint of the breath of people with lung cancer.

Discover of New Antibody Takes Step Forward Towards AIDS Vaccine

The progress made recently in HIV and AIDS research seems to have taken the media by storm. With advancements such as earlier treatment in HIV and AIDS patients, and a vaginal gel found to decrease the risk of infection, it appears we’re a step closer towards vaccination. The most recent breakthrough with the discovery of three new HIV antibodies gives hope to scientists that a vaccine will be found. Drew Halley of SingularityHub reports:

Will HIV eventually go the way of smallpox and polio? Earlier this month, scientists at the National Institute of Health (NIH) announced their discovery of three new HIV antibodies, the most powerful of which neutralizes 91% of all HIV strains. These are the strongest antibodies yet found, and they could hold the key to developing a vaccine to AIDS.

HIV antibodies themselves aren’t rare, and scientists regularly find ones that are effective against a few different strains.
