Sauropods were previously thought to have had their heyday in the Late Jurassic period. Recent fossil evidence says it was probably much earlier than that.
Do commercial hand sanitizers work on coronavirus? In the lab, yes. Studies are needed using real human hands, which come with ethical challenges.
Poliomyelitis is the name of the disease caused by the poliovirus, and it mostly affects children under the age of 5, causing paralysis in a small percent of cases. The disease had been around since the 1800s at low levels, but became an epidemic in multiple countries between the 1910s-1960s. Because polio was killing…
Poor social support is a risk factor for PTSD, but it is unknown if poor social support is also a risk factor for Complex PTSD. This study found that those with CPTSD are less likely than PTSD to describe themselves as having a strong social support system.
Scientists at University of Washington have attempted to improve upon previous population models developed by the United Nations and the Austrian Wittgenstein Centre by using different calculation techniques for two key factors - fertility and migration.
Salmonella enterica and Listeria monocytogenes are two diarrhea-causing bacteria that can make you sick when eating contaminated produce. It turns out, soil-free growing mats used to produce microgreens might be a breeding ground for these bacteria. Peat or coco coir might be a safer choice.
Today, we know DNA is where we get our traits. We know we inherit our DNA from our parents, and that our DNA contains genes. We know that we can sequence DNA to learn about what genes we have, as well as the genes of plants, animals, bacteria, viruses, and more. We can even change the DNA of living things to change…
When two stars orbit each other, it is called a binary star. In 2018, NASA’s Transiting Exoplanet Surveying Satellite (TESS) mission found a planet orbiting one of these stars by detecting changes in light levels coming from the stars.
A group of researchers gathered evidence from previous studies and, using what is known about the virus structure, made the case that the 2019 novel coronavirus was unlikely to have been intentionally engineered.
Computer models are handy tools to figure out how well our public health interventions might work in controlling the COVID-19 pandemic simply by looking at the numbers.
