Currently, the most accurate method of checking for anemia is to draw a blood sample and conduct a count of a patient's red blood cells, which contain iron-rich hemoglobin. Soon, however, a smartphone app may be able to non-invasively do the same job... Continue Reading App detects anemia by checking fingernail color Category: Medical Tags: Blood Emory University
Ordinarily, it takes two to five days to determine if harmful bacteria are present in a patient's biological samples. Within that time, any infection that's present could get much worse. A newly-developed biosensor, however, is capable of analyzing samples on the spot... Continue Reading Budget biosensor detects infections in real time Category: Medical Tags: Bacteria
A powerful new deep learning algorithm has been developed that can study PET scan images and effectively detect the onset of Alzheimer's disease up to six years earlier than current diagnostic methods. The research is part of a new wave of work using machine learning technology to identify subtle patterns in complex medical imaging data that human clinicians are unable to pick up... Contin
Also known as the thumb piano, the mbira is an African musical instrument that has been around in one form or another for at least 3,000 years. Now, however, scientists have developed a new version that – when combined with a smartphone – can detect toxic substances and possibly even counterfeit medication...

In developing nations, unscrupulous companies routinely produce counterfeit or diluted antibiotics. Unfortunately, those same countries often lack the expensive lab equipment needed to detect fakes. There could be hope, however, in the form of a simple new paper device... Continue Reading Cheap paper device detects bogus antibiotics Category: Science Tags: Antibiotic
If the mosquitoes in a given area start carrying viruses such as Zika or Dengue, then the sooner that local health authorities know, the better. And while existing mosquito-testing procedures take at least week to deliver results, a new biosensor does so in less than an hour...

Although there already are devices that allow you to objectively check if you've got bad breath (aka halitosis), they typically require a power source and an involved calibration process, plus they often aren't very sensitive or quick to respond. A newly-developed sensor, however, could change that... Continue Reading Simple, inexpensive sensor detects bad breath Category: Science Tags:
We're getting one step closer to a portable, practical and affordable "cocaine breathalyzer," thanks to research being conducted at the University at Buffalo. Scientists there have created a chip that detects the drug in samples of a person's blood, breath, urine or saliva...

If you have a small child and a swimming pool, then it's at least a little likely that you may sometimes worry about said child falling into said pool. Well, it was with that concern in mind that British electrical engineer John Barstead created the Dolphin Alarm...Continue Reading Sonar alarm system detects kids in the poolCategory: Around The HomeTags: Children Kickstarter
When the water in the rooftop cooling towers of a building's air conditioning system gets infected with Legionella bacteria, people in the building can get potentially-fatal Legionnaires' disease. Therefore, it's important to check that water for the bacteria on a regular basis. A new chip is promised to do it faster than ever...Continue Reading Chip detects Legionnaires' bacteria in minutes,
