JonathanLiuMessEquations relating speed and mass go back to Newton and beyond.

But what about relating speed and MESS?

Simply, how fast should you expect a clean kids' room to get messy?
Gad Saad, who likes to link evolution to consumption and marketing phenomena, says the length between the second and fourth finger is an indicator of high levels of prenatal testosterone and therefore risk-taking and potential financial success in adult men.

His hypothesis suggests that alpha males may take greater risks in relationships, in sports and in the financial markets, which we all sort of knew because that is the origin of the term 'alpha male'.   
At The Hazard Of His Ears

What has the hazard of a person's ears to do with science history?

The history of Arctic science, exploration and discovery is sprinkled with many as yet unsolved mysteries, many concerning the meanings of words in old documents.  In this, the first article in a short series, I present my thoughts on some of these mysteries for discussion.  By clarifying an obscure passage in an old document we may add to its credibility as a source of historical or scientific data.  Thus the solving of these mysteries will - I suggest - add to our knowledge of Arctic history, and hence of Arctic science.
In the Iowa Gambling Task, a participant is presented with four, facedown decks of cards. He or she can flip over cards from any deck. Most cards earn a reward and some cards incur a penalty. Of the four decks, some are better (contain more reward-earning cards) than others.

Over time, participants should learn which decks are best and start flipping cards only from the highest-paying decks. The test is thought to measure the emotional component of learning, or intuition—based on reward and punishment, participants begin to "feel" which decks are best and worst.
As life expectancies increase, so does the number of elderly people undergoing surgical procedures.    Recently, there has been growing about potential neurotoxicity of anesthetics and their role in post-operative cognitive decline.

Alzheimer's Disease(AD) is a devastating disease most commonly found in elderly people. It is manifested by severe memory loss, language problems, impaired decision making and affected activities of daily living.
In vitro fertilization (IVF) has brought children to millions who otherwise had difficulty conceiving so it should be a happy time.   Yet over 20% of women who undergo IVF report symptoms of depression.

The belief has been that the common denominator in women who undergo IVF - hormone therapy - is the culprit, but new Tel Aviv University shows that other factors have a large influence in who gets depressed and why and resolving those issues will make the success of the IVF greater.
Children have more energy than adults but why is it that when walking children tire first?   

Do kids,  and perhaps even shorter adults, walk differently from taller people or do they tire faster for some other reason?  Max Kleiber's work on resting metabolic rates for different sized animals found that the bigger you are the slower each gram of tissue uses energy, but how and why metabolism is regulated that has been a puzzle.
Stupid physicists, they are doomed. Spending their whole lives searching for a theory of everything, not knowing that some eighty years ago this was proven to be logically impossible. 

The internet is full with sentiments like the above. Many such posts refer to Stephen Hawking's 2002 Dirac lecture Gödel and the End of Physics.
The best way to discover whether someone is full of crap or not is to look at their past predictions.  If you're digital media expert Jim Griffin and you put your rep publically on the line predicting internet video in 2002, you're probably on the side of 'smart and right'.

Jim Griffin (onehouse.com) made a wager at LongBets that “A profitable video-on-demand service aimed at consumers will offer 10,000 titles to 5 million subscribers by 2010.”  He won, donating the $2000 prize to the EFF. Was this futurism, the random picking of potential paths by a random pundit? In his own analysis on a private list,
“What we’ve got here is a failure to communicate.”

The much-revered writers of the Golden Age of science fiction can be quite rough around the edges, even downright embarrassing on occasion. The writing is hurried, the plots of plot-driven books are disturbingly inconsistent, and the characters are primarily stock types and authorial mouthpieces. To top it off, many of these novels are ambitious, earnestly offered as novels of big ideas. These ideas are usually sympathetic (tolerance, freedom, racial equality, escape from religious tyranny), but generally reduced to platitudes expressed in long, somnolent sermons by the your standard pointy-headed philosopher-scientist.
