1.6 Grams of Protein a Day Per Kilogram of Weight
To answer the simplest question of whether taking in more protein during weight training led to larger increases in muscle size and strength, the researchers added all of the results together.
[...]
But those who did ramp up their protein gained an extra 10 percent or so in strength and about 25 percent in muscle mass compared to the control groups.
The researchers also looked for the sweet spot for protein intake, which turned out to be about 1.6 grams of protein per kilogram of body weig... 1

Children's Attention Spans are Short, and Education Deman...
The 2016 paper, “Off-task behavior in elementary school children,” was published in the peer-reviewed journal Learning and Instruction, and was funded by the Institute of Education Sciences, an arm of the Department of Education.
The researchers also kept track of how the teachers were instructing students during these observations. Not surprisingly, students went off task more frequently during whole-group instruction than during small group or individual work.

Universities Targeting Out-of-State Admissions for Tuitio...
Colorado Mesa University was typical of most public institutions in the fall of 2007, with out-of-state students making up a small number, about 5 percent, of the overall student body. But when the economic downturn hit in the fall of 2008, and state support for higher education began dwindling, Colorado Mesa President Tim Foster knew it was time to shake up the status quo. He decided to aggressively recruit out-of-state students, who pay 50 percent to 60 percent more than do Colorado residen...Folksonomies: academia admissions

Tyranny of the Gene Tempered by Junk DNA
The analogies between the genetic evolution of biological species and the cultural evolution of human societies have been brilliantly explored by Richard Dawkins in his book The Selfish Gene. The book is mainly concerned with biological evolution; the cultural analogies are only pursued in the last chapter. Dawkins's main theme is the tyranny which the rigid demands of the replication apparatus have imposed upon all biological species throughout evolutionary history. Every species is the pris... 1 notes

It is Impossible to Keep Up with New Knowledge
No man's model of reality is a purely personal product. While some of his images are
based on firsthand observation, an increasing proportion of them today are based on
messages beamed to us by the mass media and the people around us. Thus the degree of
accuracy in his model to some extent reflects the general level of knowledge in society. And
as experience and scientific research pump more refined and accurate knowledge into society,
new concepts, new ways of thinking, supersede, contradict... 1 notes
notesThe growth of knowledge is too fast for anyone to keep on top of it, even in specialized fields. Is the solution for everyone to become generalists?

The Brain is Too Expensive for Survival Purposes
My interest is in the psychological adaptations that are uniquely
human, the 10 percent or so of the brain's capacities that are not shared with other apes. This is where we find puzzling abilities like creative intelligence and complex language that show these great individual differences, these ridiculously high heritabilities, and these absurd wastes of time, energy, and effort. To accept these abilities as legitimate biological adaptations worthy of study, evolutionary psychology must bro... 1 notes
notesIt makes more sense that our capability for complex thought, music, and socialization are adaptations to prove our genetic fitness to a potential mate.

Are Humans Still Evolving?
Anybody who teaches human evolution is inevitably asked: Are we
still evolving? The examples of lactose tolerance and duplication of the
amylase gene show that selection has certainly acted within the last few
thousand years. But what about right now? It’s hard to give a good
answer. Certainly many types of selection that challenged our ancestors
no longer apply: improvements in nutrition, sanitation, and medical
care have done away with many diseases and conditions that killed our
ancestor... 1 notes
notesCulture has removed many of the selective pressures from human survival, allowing harmful mutations to build up in the genepool; meanwhile, people living in third-world countries continue to experience selective pressures from droughts, famines, and disease.

Effects of Smoking on the Fetus
Most women also realize that smoking is bad during pregnancy. Unfortunately, it can be a very hard habit to give up, even for the best-intentioned parent. Smoking is not as detrimental to fetal brain development as heavy alcohol drinking, but it acts on many other organ systems. like the heart and lungs, that compromise the baby's health in a lasting way. Babies born to heavy smokers are substantially smaller than babies born to nonsmokers, averaging about half a pound lighter. In fact, smoki... 1 notes
notesThe evidence suggests that smoking has longterm cognitive effects on children due to compromised brain development in the womb.
