Researchers are worried that a brain illness known as 'zombie deer' disease may start infecting humans

  Researchers are worried that a brain illness known as 'zombie deer' disease may start infecting humans Canadian researchers are concerned the disease could potentially start to infect humans who eat deer, elk, moose, or other members of the animal family that carry misfolded proteins.At some point, the animal will start to lose weight, stop interacting with other deer, lose its fear of humans, and may start drinking and salivating more. Ultimately, it winds up staring vacantly as it starves to death. That's why the illness is also known as "zombie deer" disease.

Rats Can Accurately Detect This Disease in Humans . Current methods for detecting TB tuberculosis, one of the top 10 causes of death worldwide, are far from perfect. But rats are coming to the rescue.Inspired by anecdotal reports that TB patients give off a specific odor

Rats can detect whether children have tuberculosis (TB)—a deadly infectious disease which generally affects the lungs—and are more effective at this task than commonly used tests, according to a new study published in the journal Pediatric Research.

Inspired by anecdotal reports that TB patients give off a specific odor, a team led by Georgies Mgode from the Sokoine University of Agriculture in Tanzania trained African giant pouched rats to sniff samples of saliva and mucus—known as sputum samples—from 982 children under five infected with the disease. These children had already been given standard smear tests at clinics in the Tanzanian capital of Dar es Salaam.

We still can't say if cellphones cause cancer

  We still can't say if cellphones cause cancer Do cellphones cause cancer? Maybe in some rats, but mobile phones and cellphone radiation probably do not cause cancer in people, government investigators say.Do cellphones cause cancer? The latest studies from the federal government show that maybe, at the highest doses for the longest periods of time, cellphone radiation might cause one type of cancer in rats.

Rats Can Accurately Detect This Disease in Humans . Tuberculosis is one of the top 10 causes of death worldwide, according to the World Health €6,000 Giant Rats to Sniff Out Tuberculosis. A Belgian NGO is training rats to deal with deadly disease which is prominent in east African countries.

Rats Can Accurately Detect This Disease in Humans . Tuberculosis is one of the top 10 causes of death worldwide, according to the World Health Organization. For over a hundred years, a rat myth in New York has claimed the city has about 8 million rats , at a ratio of one human to one rat . Not true.

Of these children, the smear tests showed that 34 children had TB. However, when the same samples were given to the rats, a further 57 cases were found. These extra cases were later confirmed with a more advanced fluorescence microscope test and the relevant clinics were notified so that infected patients who had been missed by the first examinations could receive treatment.

The rats' abilities are promising, according to Mgode, because current methods for detecting TB are far from perfect, especially in less-affluent nations in Sub-Saharan Africa and Southeast Asia where the disease is rife and cheap smear tests are commonly used.

The accuracy of these smear tests depends on the quality of the sputum samples, but often, very young children cannot provide enough saliva or mucus to be analyzed.

Here’s Why Experts Say Dim Lighting Hurts Your Brain

  Here’s Why Experts Say Dim Lighting Hurts Your Brain Neuroscientists at Michigan State University recently found that dim light can actually impair your memory and learning abilities. People who suffer from seasonal affective disorder, or have at least heard of it, know that lighting can really affect your mood. But did you know that it can also seriously impact how well you think?In a groundbreaking new study by Michigan State University, neuroscientists found that dim light can actually impair your Which means that as much as you may hate the fluorescent lighting in your office, it could actually be helping you work.

African Pouched Rat . Tuberculosis isn’t a disease you hear of often in America but it is increasingly deadly in the Saharan Africa. Research done by the World Health Organization discovered that the African Pouched Rat can sense TB and other potential germs in human saliva — and this could go a

The rats , however, are not heavy enough to trigger the explosives and stop to scratch the ground whenever the source of TNT scent is reached. Infrared vision acts as an extra sense, providing information about prey in the dark and assisting in accurately striking the target.

"As a result, many children with TB are not bacteriologically confirmed or even diagnosed, which then has major implications for their possible successful treatment," Mgode said in a statement. "There is a need for new diagnostic tests to better detect TB in children, especially in low and middle-income countries."

The new study builds on previous work conducted in Tanzania and Mozambique where African giant pouched rats were taught to pick up the scent of the tuberculosis bacterium using a similar technique to how rats are taught to trained to detect the odors released by landmines. 

Tuberculosis is one of the top 10 causes of death worldwide, according to the World Health Organization, killing 1.7 million people in 2016. More than 95% of these deaths occur in low and middle-income countries.

<p>Oil of lemon eucalyptus extract or PMD is a plant-based ingredient that has been proven to prevent mosquito bites. Here's what you need to know about PMD, plus the best mosquito repellents that contain the ingredient.</p>First things first: If you're looking for a science-backed method of repelling mosquitoes, you don't need to shy away from synthetic repellents such as DEET and picaridin. DEET in particular has been widely used for decades, and studies show it protects against mosquitoes and ticks carrying malaria, West Nile virus, Zika virus, and Lyme, according to the Environmental Protection Agency.
