Why Plastics Are Dangerous to Our Health

By Emily Folk (@EmilySFolk) It is almost impossible to avoid plastics today. They’re used to package our food, hold the water we drink, and even print our receipts at the grocery store. Though plastics have made life more convenient than ever before, could there be a downside to their prevalence in our world? Scientists are trying to find out. One area of research focuses on how regular contact with plastic might harm the human body, especially because people unknowingly ingest plastic practically every day. To quote the Graduate, “I just…

Will You Still Eat Raw Fish After Watching This Video?

Sushi, sashimi, and poke are delicious. Why? It’s because they’re all made of raw fish! But, have you ever noticed that warning about raw or undercooked seafood at the bottom of restaurant menus? Have you ever wondered why it’s there? It’s there because fish carry a ton of parasites. And if the fish aren’t prepared correctly, then those parasites can make it into your body. This fishy intersection with the wild world of parasites can teach us a lot about how these moochers help keep ecosystems healthy, and why we…

How Habits Are Formed

Got a bad habit you just can’t seem to break? That’s because a habit is literally wired into your brain. Every single thought, action, and feeling changes your brain. When repeated enough times, a habit is formed. Some are good, some are bad, but you’re not likely to forget any of them without serious effort. Millions of people, every day, wake up and brush their teeth. Why do we do this? Because we formed a habit. But how do habits form? Well, it all comes down to neuroscience and the…

Depression May Speed up Brain Aging Health 

Depression May Speed up Brain Ageing

By Kate Stone Psychologists at the University of Sussex have found a strong correlation between depression and the speed at which the brain ages. Although scientists have previously found that people with depression or anxiety have an increased risk of dementia later in life, this is the first study that provides comprehensive evidence for the effect of depression on the decline in overall cognitive function (also referred to as cognitive state). The researchers behind this new study are hoping that their work will lead to greater public awareness of the…

New Ebola Vaccine in Development

By Michelle Dookwah @mtdookwah Only a few summers ago, “Ebola” became a household word as the worst outbreak of the virus in history ravaged its way across western African nations and threatened health safety worldwide. It became easier to not think about the Ebola virus once the urgency of the crisis passed, and now news media is filled with other medical emergencies such as Zika or measles outbreaks—although there is a vaccine for the latter (cough, cough). However, several research groups haven’t forgotten about the devastation caused by the hemorrhagic…

Plastic Pollution: An Emerging Threat Beneath Our Feet

By Emily Rhode @riseandsci Tiny plastic particles that can barely be seen by the human eye have made their way from our soil into everyday items we know—from earthworms to honey to the beer that we drink—bringing toxic chemicals with them wherever they go. The saying goes that what we can’t see can’t hurt us. Yet, what if these unseen particles are not only hurting us but also changing the entire course of biological evolution? Researchers in Germany have issued a new warning that these human-generated “microplastics” could potentially be…

Fabulous Fat: Lipid-Based Nutrient Supplements Combat Malnutrition

By Shayna Keyles @shaynakeyles Malnutrition affects hundreds of millions of children around the world. As of 2017, about 23 percent of children under five suffer from stunted growth because of malnutrition and about 8 percent experience extreme wasting, which is characterized by a low weight-to-height ratio. Although over the years many treatments have been developed that reduce chances of mortality, increase weight gain, and improve lean tissue creation—all signs of healthy development—more work is necessary to create an inexpensive, accessible, and long-term solution. Médecins Sans Frontières (MSF; also known as…

New Ways to Reduce Antibiotics in Food Animals by 2030

By Neha Jain @lifesciexplore In a new study, researchers in the United States and Europe propose three measures—capping antibiotic use in farm animals, imposing a fee for veterinary use of antibiotics, and limiting meat intake—that, together, can reduce the use of antibiotics in food animals by up to 80 percent by 2030. Antibiotic resistance results from antibiotics overuse Overuse of antibiotics, particularly in animals for food, is the main cause of the spread of resistance whereby antibiotics lose their effectiveness, and infections become untreatable, leading to what many scientists call…

Vampires, or People with Blood Disorder?

By Michelle Dookwah @mtdookwah Vampires, or People with This Blood Disorder? Autumn is here, and with it comes cooler temperatures, shorter days, and a favorite fall holiday: Halloween. These last two features of the season have more in common than you may have realized. The shorter days of fall mean less daylight in the evening hours, and this might have a significant impact on the day-to-day lives of certain individuals with a particular blood disorder called erythropoietic protoporphyria. Erythropoietic protoporphyria (EPP) is a rare genetic disorder that results in hypersensitivity…
