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
After a new star is born, the surrounding gas and dust flattens out into a rotating disk. Some of that matter will condense, eventually forming the planets that circle the star. Unfortunately, it is challenging to watch the formation of a new planet. Light from the star tends to drown out light from the planet. Astronomers have only been able to spot planet-like-objects in these … Continue reading It’s a planet! Scientists find newborn planet for the first time
In order to adapt to their environments, it is important that bacteria be able to mix up their genetic code. One way that bacteria do this is by taking up bits of free-floating foreign DNA that can be released by other kinds of bacteria into their environments when they die. This process is called ‘transformation.’ The pieces of DNA can occasionally encode components that make … Continue reading Bacteria snatch up foreign material using specialized arm-like structures
Our bodies contain numerous cell types that look drastically different and perform various functions that allow us to eat, breathe, move, and reproduce. While all cells have the same DNA as a “blueprint”, their working set of proteins can vary drastically. The process of making protein from DNA is known as the “central dogma”. However, it is not a linear step, but instead requires two … Continue reading Central Dogma
Approximately 12% of Americans experience migraines. For some people, the attacks are so frequent and painful that episodes can be incapacitating. Historically, doctors have tried a variety of approaches to treating the condition, including drugs that numb nerves, medications that constrict blood flow, and as well as a variety of behavioral approaches. While some patients have found relief using these methods, many are not helped … Continue reading Migraines: Can New Antibody Treatment Help Stop Treatment Resistant Migraines
Early-stage research has identified a compound that stops pesky colds in their tracks – useful as a potential cold cure. Although adults are bothered by an average of 2-3 colds per year, colds can “cause serious complications in people with conditions like asthma and [chronic obstructive pulmonary disease] (COPD),” lead researcher Edward Tate, Chemical Biology Professor at the Imperial College London, told ScienceDaily. “A drug … Continue reading A Future Cure for the Common Cold?
There are an estimated 37.2 trillion cells in the average adult human body. 37.2 trillion is a staggering number, especially when we remember that we all develop from a single fertilized egg cell. So how does one cell become 37.2 trillion cells? Through mitosis. Mitosis is the process of cell division, in which one cell produces two new daughter cells that are genetically identical to … Continue reading Mitosis
