Changes in the visual systems of newly diagnosed Parkinson’s disease patients may provide important biomarkers for the early detection and monitoring of the disease, according to a new study published online in the journal Radiology.

In their work toward 3-D printing transplantable tissues and organs, bioengineers and scientists from Rice University and Baylor College of Medicine have demonstrated a key step on the path to generate implantable tissues with functioning capillaries.

Many scientists are paying new attention to prebiotics, that is, molecules we eat but cannot digest, because some may promote the growth and health of beneficial microorganisms in our intestines, says nutritional microbiologist David Sela at the University of Massachusetts Amherst. In a new study, he and colleagues report the first evidence that certain beneficial gut bacteria are able to grow when fed a carbohydrate found in cranberries and further, that they exhibit a special nontypical metabolism.

Why do some people prefer stable, predictable lives while others prefer frequent changes? Why do some people make rational decisions and others, impulsive and reckless ones? UCLA behavioral neuroscientists have identified changes in two brain regions that may hold answers to these questions.

Scientists have devised a simple test for an earlier and more accurate warning of returning bladder cancer than existing methods, according to research(link is external) published in the British Journal of Cancer(link is external).

Titus Divala has seen the effects of malaria first-hand.

Now a University of Maryland researcher, he was born and raised in Malawi, where the mosquito-borne infectious disease is the third most common cause of death.

Today marks the one year anniversary of Pokémon GO’s worldwide release that sent crowds hiking through parks, meandering into streets and walking for miles in search of Pokémon, those cute little digital characters that appear in real locations on your smartphone.

Researchers have called for health professionals and climate forecasters to work more closely together ahead of extreme weather events and gradual climate change to help prevent the spread of infections.

It’s slimy, it’s stinky and like a creature from a summer horror flick, it’s coming back to Alberta lakes this vacation season.

Blue-green algae—the scum-inducing bacteria to blame for the annual ‘eww’ factor in local swimming holes—should be blooming by mid-July, says a University of Alberta water expert.

Each year millions of animals are used in Canada for medical research and toxicity testing, but a growing body of scientific evidence points to the difficulties of treating humans like 70-kg mice.

After years of using rodents to conduct heart disease research, Charu Chandrasekera began to question the value of using animals as stand-ins for humans. She lost her fervour for animal research after her father suffered a heart attack, bringing home to her the realization that human relevance must be at the forefront of biomedical discoveries.
