Liverwort as an alternative to medical cannabis

Cannabinoids are a family of chemical compounds that bind to cannabinoid receptors found on various cell types in the body, and alter the release of neurotransmitters. Endocannabinoids are produced naturally in our bodies (e.g. anandamide is associated with the euphoria of a “runner’s high”). On the other hand, phytocannabinoids are found in plants – of course, the most well-known phytocannabinoid is tetrahydrocannabinol (THC) and is responsible … Continue reading Liverwort as an alternative to medical cannabis

An effort to make moral machines finds cultural differences in human morality

A driverless car is speeding down a road and can’t stop. Either it hits an elderly woman crossing the street, or it swerves out of the way and kills its passenger, a young child. Whose life should be spared? As driverless cars become a reality, the answer to the famed “Trolley problem” becomes increasingly pressing. Unlike humans, self-driving cars don’t have an internal moral code; … Continue reading An effort to make moral machines finds cultural differences in human morality

Treating Men and Women Differently: Sex differences in the basis of disease

by Nathan Huey figures by Daniel Utter Sex is one of the most obvious candidates for a first step towards individualized healthcare.

Safe Transfusions: Enzymes that can convert blood to type O

Imagine you are rushed to the hospital after an injury and need an emergency blood transfusion. If there is no time to test your own blood type, the hospital may give you type O blood. This is because type O is a “universal type.” Blood types A and B each have distinct sugars attached to the red blood cells (type AB has both types of … Continue reading Safe Transfusions: Enzymes that can convert blood to type O

Probiotics prevents dangerous pathogen infection by making the bacteria ‘deaf’

If you’ve visited a supermarket recently, you might have noticed that yogurts and kombucha are taking up more shelf space. These products are two popular examples of probiotics: living bacteria touted to provide human health benefits. It’s not just a millennial fad – the probiotics market is projected to be over $60 billion by 2023. The accepted belief is that good bacteria drive out bad … Continue reading Probiotics prevents dangerous pathogen infection by making the bacteria ‘deaf’

Using Satellites to Protect Shark Sanctuaries

Sharks play an important and often overlooked role in the ocean ecosystem. As apex predators, or predators at the top of their food chain, sharks regulate the diversity and diets of species below them, ensuring a healthy ocean habitat. For instance, the decline of sharks in many areas has been shown to directly correlate with the demise of coral reefs and seagrass beds. Despite their … Continue reading Using Satellites to Protect Shark Sanctuaries

The Quest for Better Bandages Turns to Nanofibers

Our skin is a protective barrier to bacterial infection, but damage to the skin allows bacteria to enter. Normally, our immune system kills the bacteria and allows wounds to heal. However, certain diseases can overload the immune system and lead to heavy infection. Antibiotics are commonly used to treat heavy bacterial infection, but bacteria can develop drug resistance after too much exposure. A team at … Continue reading The Quest for Better Bandages Turns to Nanofibers
