Screening for some 17 diseases has never been this fast and efficient.
A device invented by a multinational team of scientists can detect 17 diseases through analyzing patterns of exhaled molecules. The technique of assessing a patient’s breath to diagnose an illness is an ancient practice, dating back from about 400 BC. Physicians then can determine a patient’s disease based on the odor of one’s breath or of the body fluids.
The team, led by scientist and engineer Hossam Haick from Technion−Israel Institute of Technology, notes that:
Since antiquity (∼400 BC), physicians learned to evaluate their patients by exhaled volatile organic compounds (VOCs), among other means, that are linked to diseases. For example, the stools and urine of infant noblemen were smelt daily by their physicians. This approach rests on the fact that a compendium of VOCs with relatively low molecular weight expresses distinct and immediate changes as a consequence to pathophysiological processes occurring and altering the body’s metabolism. Experimental findings show that VOCs can be detected directly from the headspace of the affected cells, blood, exhaled breath, and/or other body fluids.
So how does this device work?
The invention utilizes artificially intelligent nanoarray technology that “relies on cross-reactive (i.e., semiselective) nanotechnology-based sensor arrays, using pattern recognition,” consequently detecting unique ‘breathprints’ that correspond to a disease, and quite possibly, its classification. Put simply, each time a diseased patient exhales, specific types of molecules are released. It is this specificity in molecular composition that allows the device to identify the disease process.
How a breathprint is formed
The research team writes:
“A total of 2,808 breath samples were collected from 1,404 subjects having one of 17 different disease types that had been put into three main categories (cancerous, inflammatory, and neurological diseases) and one group of uncorrelated diseases, as well as a group of healthy controls.”
They found out that each of the 17 diseases that they were trying to identify registered different “breathprints.” The diseases include:
- Head and neck cancer
- Lung cancer
- Gastric cancer
- Colorectal cancer
- Kidney cancer
- Bladder cancer
- Ovarian cancer
- Prostate cancer
- Irritable bowel syndrome
- Ulcerative colitis
- Crohn’s disease
- Atypical Parkinsonism
- Idiopathic Parkinsonism
- Multiple sclerosis
- Pulmonary arterial hypertension
- Chronic kidney disease
On why it is more practical to study a patient’s breath as compared to other body fluids, the team explains:
“Of these body fluids, exhaled breath is the most accessible and useful VOC source for monitoring bodily health and disorder. This is because exhaled breath is easily and noninvasively accessible; it is suitable for high compliance; it provides a matrix of relative low complexity, and it can be handled safely and repeated as frequently as desired.”
Researchers have discovered unique molecular compositions of 17 diseases based on breath analysis.
The group further tells us:
Consequently, the presence of one disease would not screen out others—a prerequisite for developing a new generation(s) of biomedical devices for personalized diagnosis and classification of diseases in a noninvasive, inexpensive, and portable manner. The artificially intelligent nanoarray had a low or no vulnerability to clinical and demographical confounding factors.
Further research and tests are required before this device is used for a larger population of patients. Ultimately, what we are hoping for is a device that can rapidly and correctly diagnose a patient’s condition, consequently facilitating prompt and effective treatment and improving patient outcomes.
The study has been published in the journal ACS Nano.
Scientists Compare Matter and Antimatter for the First Time Using Light Spectrum
Does antimatter matter?
Theory suggests that when the Big Bang occurred, equal amounts of matter and antimatter were created. However, such matter-antimatter symmetry is being challenged as the amount of matter in the universe is considered to exceed that of antimatter.
We all know that matter is anything that occupies space and has mass. Antimatter, on the other hand, is the counterpart of matter. An atom is composed of a positively-charged nuclei called proton and is orbited by negatively-charged particles called electrons. In the case of the antimatter, it's the other way around. An atom of an antimatter consists of a negatively-charged nuclei called antiproton and positively-charged electrons called positrons. Now, in spite of being counterparts, matter and antimatter may have a permanent hate-and-only-hate type of relationship, as both will be annihilated once they come in contact with each other and result in the release of a significant amount of energy.

Scientists Reveal What Is The Very First Animal On Earth
Have you ever thought what actually is the very first animal on earth? Could it be the creepy crawly creatures and insects? Well if we take the bible as reference it says in Genesis 1:20, then we will learn that "There was evening and there was morning, a fourth day. Then God said,'Let the waters teem with swarms of living creatures'"
Surprisingly, science concurs with this!
When you think of "let the waters teem with swarms of living creatures", what animal can you think of? Do you envision fishes only? Or maybe it is a plankton?
Finland to Become First Country in the World to Get Rid of All School Subjects
Finland’s progressive teaching method takes on an integrated approach to learning, and it’s nothing like the method that’s been used for centuries.
For centuries, the formal educational system has been roughly the same. Topics are divided into subjects, and those subjects are taught independently of each other. There are subjects like Math, Science, Language, and Physical Education that are taught by different teachers at different times.
In Finland, a country known for its progressive views on teaching, this method of teaching will now replaced by a new and possibly more effective method. Finnish officials want to remove school subjects from their curriculum.
According to the head of the Department of Education in Helsinki, Marjo Kyllonen,
