One of the biggest challenges of the COVID-19 pandemic has been accessible, low-cost, and rapid detection systems for tracking the spread of the virus. At the Engelhart and Adamala lab, we developed a detection system called Apta-NASBA that can detect SARS-CoV-2, as well as other pathogens, using a different fluorescent colour output per pathogen.
Fad diets promise weight loss and a long healthy life. But, no diet follows through like the Mediterranean diet does.
When you look at places with the highest proportion of centenarians — no, not centaurs the mythical man horse combo; rather, people that live to be over 100-years-old — the small island of Sardinia nestled in the Mediterranean has the third highest population in the world right behind the US and Japan.
Scientists know that the high levels of olive oil in Sardinian diets explains why they live so long. But they didn’t know why until now.
Fly eyes play an important role in picking up information about the world around them, finding food and avoiding danger. But before this information can become useful, neural circuits in the brain need to simplify and extract the important components. Within milliseconds these little insects make complex decisions about where to turn, what to eat and what to avoid.
Duchenne muscular dystrophy is a fatal muscle wasting disease that affects 1 in 3,500 boys, totaling 620 baby boys born each year in the US.
Age-old existential questions such as “how did we get here?” and “are we alone?” bridge the gap between science and philosophy. Scientists who study astrobiology -- the study of the story of life past, present, and future in the Universe -- seek to answer these questions.
The field of astrobiology is as big as the Universe itself; it encompasses many disciplines including physics, chemistry, biology, astronomy, geology, and planetary science, to name a few.
We typically expect natural selection to improve the condition of a species, leading to their long-term survival; however, 99.9 percent of all species on Earth are now extinct. It seems that natural selection might be pretty good at helping us make it through today, but pretty awful at preparing us for tomorrow.
Plants inhabit many environments across the globe, and some groups can survive extreme conditions. One of these groups is the amaranth family. Members of this family, including several important crops such as amaranth, quinoa, spinach, and sugar beet, are well known for evolving adaptations to survive extreme environments, such as C4 photosynthesis in hot and often dry places and tolerance to highly elevated levels of salt or heavy metals.
Imagine that you are walking in a tropical forest in Costa Rica where most trees look like the ones in Minnesota during the winter -- leafless. You might be wondering how this can be possible. What can be causing these trees to lose their leaves?
The answer is water. Water in these systems control when trees have leaves or when they lose them. This change in tree foliage is completely normal in tropical dry forests where trees lose their leaves in late October or early November when the rains stop.
