Panchin knows the idea of cancer-derived animals sounds far-fetched — so much so that, in the paper, he and his co-authors refer to them as Scandals (an acronym for “speciated by cancer development animals”). [...] According to Panchin’s three-step scenario, a Scandal would start off as a cancer, but not just any…
Ancient scribes learned not merely to read and write, but also to use catalogues, dictionaries, calendars, forms and tables. They studied and internalised techniques of cataloguing, retrieving and processing information very di
Objective: To investigate the association between the sense of “life worth living (ikigai)” and the cause specific mortality risk. The psychological factors play important roles in morbidity and mortality risks. However, the association between the negative psychological factors and the risk of mortality is…
Recent research has shown that exhaust from lungs (part of excretion) is a major factor in weight loss. Burning 10 kg human fat requires inhalation of 29 kg oxygen. This produces 28 kg carbon dioxide and 11 kg water. As food and drinks are temporarily stored in the human stomach and bowels, the body weight is…
North Carolina provides a recent example of science-based policy. The science itself was a study of voting habits among the population of the state. In 2013, North Carolina passed new voting restrictions. To inform those restrictions, the legislature commissioned a study on voting habits by race, and then wrote into…
I recognize Map Readers because they often like to work independently, but they are most comfortable when they have specifi c instructions or procedures to follow. Th ey often take more time and work deliberately, showing all their steps on homework or taking detailed notes in class or during group work. Explorers are…
The first study to assess directly the risk of cancer after CT scans in childhood found a clear dose-response relationship for both leukemia and brain tumors: risk increased with increasing cumulative radiation dose. For a cumulative dose of between 50 and 60 milligray or mGy (mGy is a unit of estimated absorbed dose…
In the breakdown of results, the study authors from Group Health Research Institute and University of California, Davis note that the risk of developing leukemia was highest from head scans for kids under age 5 with a rate of 1.9 cases per 10,000 CT scans. Younger children and girls seemed more susceptible to solid…
The study of domesticated animals since Darwin’s influential work (1868) has culminated in the formation of a set of changes that are claimed to distinguish domestic populations from wild species (for recent outlines of these see Price 1984, 1999; Hemmer 1990; Tchernov and Horwitz 1991; Hall 1993; Teichert 1993; Smith…
There is nothing really the matter with the concept of g; it is just that we have misused it by making it the omnipresent concept in our study of cognitive abilities. Intelligence is important on three levels, namely, brain physiology, individual differences, and social trends (collectively, BIDS). The core of a BIDS…
A well-established, graded, inverse association exists between cardiorespiratory fitness (CRF) and risk of cardiovascular disease (CVD) as well as all-cause mortality in numerous healthy and clinical adult populations.1- 3 Compared with those classified in the lowest CRF category (<7.9 metabolic equivalents [METs])…
The battle of living things against cancer began so long ago that its origin is lost in time. But it must have begun, in a natural environment, in which whatever life inhabited the earth, was subjected, for good or ill, to influences that had their origin in sun and storm and the ancient nature of the earth. Some of…
awking has written down an equation which looks rather like Planck's equation. Hawking's equation is S = kA, where S is the entropy of a black hole, A is the area of its surface, and k is a constant which I call Hawking's constant. Entropy means roughly the same thing as the heat capacity of an object. It is measured…
Imagine the history of the galaxy with respect to extraterrestrial intelligence. Very early there were only first generation stars, no heavy metals and therefore no possibility of life, much less intelligence. That's Stage One. In Stage Two planets with heavy metals form from the starstuff processed in the previous…
when a child is upset, logic often won’t work until we have responded to the right brain’s emotional needs. We call this emotional connection “attunement,” which is how we connect deeply with another person and allow them to “feel felt.” When parent and child are tuned in to each other, they experience a sense of…
Whenever a statistician wants to predict the likelihood of some event based on the available evidence, there are two main sources of information that have to be taken into account: (1) the evidence itself, for which a reliability figure has to be calculated; and (2) the likelihood of the event calculated purely in…
Do you know the PDF of your shampoo? A PDF refers to a “partially diminished fraction” of an ecosystem, and if your shampoo contains palm oil cultivated on clear-cut jungle in Borneo, say, that value will be high. How about your shampoo’s DALY? This measure comes from public health: “disability-adjusted life years,”…
We found our second Blue Zone on the other side of the planet, about 800 miles south of Tokyo, on the archipelago of Okinawa. Okinawa is actually 161 small islands. And in the northern part of the main island, this is ground zero for world longevity. This is a place where the oldest living female population is found…
Cancer, we now know, is a disease caused by the uncontrolled growth of a single cell. This growth is unleashed by mutations—changes in DNA that specifically affect genes that incite unlimited cell growth. In a normal cell, powerful genetic circuits regulate cell division and cell death. In a cancer cell, these…
In 1838, Matthias Schleiden, a botanist, and Theodor Schwann, a physiologist, both working in Germany, had claimed that all living organisms were built out of fundamental building blocks called cells. Borrowing and extending this idea, Virchow set out to create a “cellular theory” of human biology, basing it on two…
