A theory is a very precise thing in science - yet some scientists can't resist using the term to lend intellectual weight to what may be a hypothesis and is likely just reasonable speculation. It's a large part of the reason why the term has become colloquialized, and 'wellness' is equivalent to gravity in the minds of some.

Physical science is not immune. String Theory put theory in the name, so it gets to skate on the edges of truth, but theoretical physicists are trying to recapture the Golden Age of the 1930s, plus write a bestselling book. Astrophysics should know better. Yet many have still used the word theory to describe the "glitch" and "wobble" detected among pulsars, despite having no basis for it.
It's been shown that there is no hiring deficit for women in science; women have been hired far more than men for new jobs. Yet women's groups have continued to point to total numbers as the problem, as if to say older men who have been supportive of more diversity and are making it happen on hiring committees should be fired without cause to open up more jobs for women.

Only the weakest candidate wants to be hired as part of a quota. There has to be a better way.
Use of performance enhancing drugs is a major problem in many competitive sports and the 2017 prohibited list includes over 300 substances. However, the scientific evidence around these substances is scarce, partly because it is impossible to do trials with professional cyclists who are subject to anti-doping regulation.

Meanwhile, media attention given to performance enhancing drugs may encourage amateurs to try them. But it is unlikely to help, according to a new paper published in The Lancet Haematology journal.
Hydrogen peroxide (H2O2) is best known for use in bleach and hair treatments and is often invoked as a scary chemical by environmental groups promoting concern about food and products, but it is produced naturally in our bodies. A new study shows it is a useful chemical across nature; plants use it to control how their cells react to varying levels of light.

Like preventing plant sunburn. 

Hydrogen peroxide is a by-product of photosynthesis in parts of plant cells called chloroplasts, much like it is in our bodies by cellular respiration. Using a fluorescent protein that detects hydrogen peroxide, the researchers behind a new study in Nature Communications observed how H2O2 moves from chloroplasts and can be detected in cell nuclei. 
What will cost $400 billion, a giant leap over California’s total health care budget for 2018 of $179.5 billion, yet is not mentioned by California lawmakers? California's free "single-payer" healthcare proposal.
We're in a lifelong struggle against nature every single day, the ultimate arms race. Viruses have continually infected humans just as they do today.

Some early viruses even became integrated into our genome and are now known as human endogenous retroviruses (HERVs). Over millions of years, they became inert due to mutations or major deletions in their genetic code.

Today, one of the most studied HERV families is the HERV-K family, which has been active since the evolutionary split of humans and chimpanzees with some members perhaps actively infecting humans within the past couple hundred thousand years.
