Why is it that some people get really sick from COVID-19, and others don’t? The answer may lie in a weakened innate immune response. Continue reading Severe vs Mild COVID-19 infections: differences in immune responses
Scientists discovered that a family of proteins known as Sestrins can actually mimic the beneficial effects of exercise. This could potentially be useful for maintaining the health of people who have difficulty moving and exercising. Continue reading Could we replace exercise with protein supplements?
by Nivanthika K. Wimalasena figures by Rebecca Clements Imagine going in for a surgery where the surgeon, instead of looking down and seeing only your swollen leg, can see the exact location of your fracture before making a single incision. Now imagine that this doesn’t require x-ray vision or the stuff of science fiction, but is possible through augmented reality (AR), used to overlay an image … Continue reading Augmented Medicine: the power of augmented reality in the operating room
by Alex Cabral figures by Sean Wilson In 2003, with the completion of the Human Genome Project, the entire human genome was sequenced for the first time. The sequencing cost nearly $1 billion and took 13 years to complete. Today, the human genome can be sequenced for about $1000 in less than two days. Industry leaders hope to bring that cost down to just $100 within … Continue reading The Computer Science behind DNA Sequencing
by Lara Roach figures by Rebecca Senft In Greek, macrophage means “big eater,” and that is exactly their job. Like a growing teenager or athlete after a big game, macrophages are activated immune cells whose primary focus is to “eat.” But instead of, say, a plate of pasta, macrophages take in and digest pathogenic microbes, unhealthy molecules, and even other cells in the body when they … Continue reading The Big Eater: How the immune system alters the pancreas during obesity
Over the past decade, the gut microbiome and its effects on human health have become a topic of considerable interest in the scientific community and popular media. The gut microbiome is composed of bacteria that naturally reside in the gastrointestinal (GI) tract, which have an effect on various biological processes such as digestion, metabolism, regulation of the immune system and protection against pathogens. Interestingly, researchers … Continue reading Bacteria may live naturally inside the human brain
by Ilia Gelfat figures by Nicholas Lue Whether you are perusing the aisles of your local grocery store or scrolling through news articles, there’s a term that has been hard to miss in the past few years – probiotics. You might know it has something to do with bacteria helping digestion, but this broad view of the concept might leave you fuzzy on some of … Continue reading Probing Probiotics: the scientific process behind the hype
As our planet warms, the effects of heat on the human body will become important information. The human body is capable of dealing with heat, but reprieves are needed to allow our systems to rest, else our bodies become over-stressed. This reprieve often comes in the form of night, when temperatures typically cool. During heat waves, nights remain toasty, and reprieves only exist for those … Continue reading Heat waves hurt your brain: the argument for window AC units
