In our daily life, we unfortunately have become used to seeing images of tumors and melanomas. You may have noticed that they’re are not entirely symmetric. This asymmetry is useful to doctors in their diagnoses, but why are they asymmetric?
Have you ever answered a phone call from a stranger and had them introduce themselves and then ask how you are doing? Somewhere, someone created that tactic with the belief that it makes callers seem interested in your life but because you know they are not, it is probably annoying.
The three recent appearances (and two subsequent removals) of “monoliths” in Romania, Utah and California are intriguing examples of what can capture the public’s imagination.
These constructions are metallic-looking structures about three or four metres tall, with a simple geometric design and reflective surface.
Nearly every sort of diet has appeared on the New York Times bestseller list by now, all claiming to have a foundation in science. Yet one key reason some among the public are distrustful of epidemiology statistics on masks and social distancing is that epidemiology is also used to statistically link nearly every food or chemical to harm or longevity.
As medical care has improved, doctors are able to screen for cancer earlier than ever, and that is why cancer cases in young adults and adolescents are prevalent enough that they can be considered a distinct population.
Age remains the biggest factor for everything, of course, if you live long enough you are going to get cancer of some kind, it is built into our biology, but the increase in screening and therefore diagnoses means young adults can be considered distinct from pediatric and adult cancers and have their own middle ground for research.
Nearly all of the atoms that make up the our planet and us were forged in stars and the carbon most important to life as we know it was made by the triple-alpha process. The process starts with alpha particles, cores of helium atoms, with each alpha particle is made up of two protons and two neutrons. The triple alpha process is just what it sounds like; three alpha particles are fused inside a star, creating a new particle with six protons and six neutrons - the most common form of carbon in the universe - with a surplus of energy, a Hoyle state. That Hoyle state can split back into three alpha particles or relax to the ground state of stable carbon by releasing gamma rays.
When your Xbox is a gaming console and a 4K Blu-Ray player, you don't need two devices, and when your phone is a camera and a video recorder, there are two fewer things to buy - and eventually throw away.
As smart devices have become more integrated, and more commodities like a dishwasher than technology events, people own fewer things and keep them longer. That means less electronic waste. Yet the story we get from environmental groups is that e-waste is the fastest growing material pollution and only donations to lawyer-run groups can stop it.
In the not so distant future, checkbooks will take their
rightful place in museums alongside answering machines, VCRs and folding paper maps.
Online bill-paying and Apple/Google Pay have narrowed the times when it’s
necessary to resort to the clunky paper-and-pen based payment method, and many
growing up today have never touched one at all. It’s clear the way we handle
our finances is changing. So why not bring the concept of money itself into the
In the United States, meat substitutes like Beyond Meat and Impossible Foods are now fixtures in culture. Vegetarians who miss meat want to eat them because they use plants while environmental activists don't want to eat them because they use science. That keeps them in the public eye.
Dolutegravir, the HIV wonder drug and current first-line treatment, is less effective in sub-Saharan Africa, and the reason is as old as evolution itself - mutation.
As HIV copies itself and replicates, its genetic code (RNA) can change. While a drug may initially be able to suppress or even kill a virus, certain mutations can allow the virus to develop resistance to its effects. If a mutated strain begins to spread within a population, it can mean once-effective drugs are no longer able to treat people.
