Ancient virus infection is linked with addiction

October 10, 2018

Many regions in the human genome are composed of “junk DNA” that do not code for proteins in the cell.  While these DNA codes are generally viewed as redundant and seemingly serve no particular function in the human body, some codes could be evidence of evolutionary scars left behind from ancient viral infections from the time of our primate ancestors.

Dachshund receives 3D-printed skull replacement

October 11, 2018

Patches, a nine-year-old dachshund, is now cancer-free thanks to a group of researchers.  Veterinary surgical oncologist Michelle Oblak from the University of Guelph’s Ontario Veterinary College and Cornell University’s small-animal surgeon Galina Hayes were the researchers who accomplished this veterinary first.

Blood cells can potentially carry treatment for TTP directly to where it will work best.

Trojan Horse method could treat a rare blood disorder

October 4, 2018

Remember the tale of the Trojan Horse?  The Greeks gift Troy a large, wooden horse as a peace offering. Then, at night, soldiers spill out of the belly of the gift and open the doors to Troy, laying waste to the city and effectively ending a 10-year war. It may be ancient Greek mythology, but the medical field had something important to learn from it: Attach medicine to a vehicle that can take it directly where it needs to go, then unleash it to do what medicine should. It’s not the same as decimating an entire population, but it’s just as important when human lives can be saved.


Nanotherapy offers hope for renal cell carcinoma

October 4, 2018

Kidney cancer is among the 10 most common cancers in both men and women. In adults, renal cell carcinoma is the most common type of kidney cancer. The American Cancer Society predicts that there will be 65,340 new diagnoses and 14,970 deaths due to renal cell carcinoma in 2018. A novel treatment has been developed that may be able to reverse drug resistance in renal cell carcinoma, using nanotherapy in combination with chemotherapeutic drugs.

Biomarker is discovered for study of Alzheimer’s

October 4, 2018

New study reveals four major personality types

October 4, 2018

As early as Hippocrates’ time, people have pondered on the best way to classify personalities. In fact, Hippocrates came up with one of the oldest personality type systems in the world, where he defined four personality types based on a person’s “humor” or the proportion of bodily fluids in one’s body. The predominant form of fluid determines the person’s appearance, behavior and psychological type.

Octopuses and humans share serotonin receptors

October 4, 2018

Scientists have found preliminary evidence that humans and octopuses have an evolutionary link that diverged over 500 million years ago. Serotonin receptors conserved in the brains of both octopuses and humans show that they both exhibit similar behaviors.

Lunar swirls are remnants of moon's geological past

September 26, 2018

Like a comforting presence, the moon is constantly circling above our heads and shining down on us when the sun sets, lighting up our night sky. But for an object that is always hovering near by, it has features that we are still unable to explain. Lunar swirls look like bright, beautiful clouds scattered across the moon’s surface, but why and how they got there was always a mystery.

Study finds barriers to expressing gratitude

September 26, 2018

A study conducted by Amit Kumar and Nicholas Epley at the University of Chicago (UChicago) found that people routinely undervalue the benefits of expressing gratitude. Their findings suggest that the disconnect between the expresser’s expectations and the recipient’s experience may prevent people from conveying gratitude, such as through sending letters that increase positive feelings for the recipient and expresser.

Research shows that expressing gratitude is important for social relationships.

The brain’s opioid system may lead to overeating

September 26, 2018

Most people have had the experience of being full, yet still eyeing the plate of fries sitting at the end of the table. As friends and families continue to chat around the dinner table after a three-course meal, hands continue to subconsciously reach out, time after time, for more food. But what physiological process actually takes place when someone becomes excessively full from food?
