Breath test can save money and catch cancer early

Breath test can save money and catch cancer early

Health
The only way to test for symptoms of stomach or esophageal cancer is to undergo an upper endoscopy, a test that can be invasive, cost thousands of dollars and has a small percentage of success in actually finding a tumor. Researchers in the U.K. wanted a diagnostic tool that would be easier and cheaper to test for these cancers so they used a noninvasive breath test to collect samples of 500cc of exhaled breath from 335 people, 172 of which they knew had those cancers, after a minimum four-hour fast. The exhaled breath was quickly analyzed for five previously identified volatile organic compounds (VOCs), known to have some association with gastric and esophageal cancers (VOCs happen with other cancers, including lung, bladder, and breast). The researchers were looking for evidence of bu...

Why a faecal transplant could save your life

Health
The faecal transplant, also known as trans-poo-sion, surely has the title of medicine's most disgusting procedure. It is pretty much what you are imagining - part of a faecal stool is taken from one person and given to another.The purpose is to introduce new beneficial microbes to the receiving patient's digestive system.And it can be life-saving. It shows just how important microbes, which colonise nearly every surface of our body, are to our health. The gut is an exceptionally rich world with many different species of micro-organisms interacting with each other and our human tissue. Down in the dark, oxygen-deprived depths of your bowels is an ecosystem as rich as a rainforest or coral reef. But a bacterium called Clostridium difficile (C. difficile) can take over and dominate the bowels...
Conservationists use astronomy software to save species

Conservationists use astronomy software to save species

Science
Researchers are using astronomical techniques used to study distant stars to survey endangered species.The team of scientists is developing a system to automatically identify animals using a camera that has been mounted on a drone.It is able to identify them from the heat they give off, even when vegetation is in the way.Details of the system were presented at the annual meeting of the European Astronomical Society in Liverpool, UK.The idea was developed by Serge Wich, a conservationist at Liverpool John Moores University, and Dr Steve Longmore, an astrophysicist at the same university. He says that the system has the potential to greatly improve the accuracy of monitoring endangered species and so help save endangered species."Conservation is not only about the numbers of animals but also...
