 Neurons Use Viruses to Share Information and Learn

When genes are activated, the instructions encoded within their DNA are first transcribed into a related molecule called RNA. Shepherd’s colleague Elissa Pastuzyn showed that the Arc shells can enclose RNA and move it from one neuron to another. And that’s basically what retroviruses do—they use protein shells to protect their own RNA as it moves between cells in a host. So our neurons use a repurposed viral gene to transmit genetic information between each other in an oddly virus-like...

 Health Concerns Spark Adult Interest in Science

Beginning in middle age and continuing through later adulthood, individuals are often motivated by events in their own lives or the lives of significant others to obtain health-related information.^^ Health-related concerns draw many adults into a new domain of science learning. At the same time, with retirement, older adults have more time to devote to personal interests. Their science learnmg addresses long-standing scientific interests as well as new areas of interest.^^ Adults differ fr...

 Mental Illness is Not Correlated with Genius

What madness may have to do with creativity and genius has continued to intrigue down to this day, with scholars arguing for and against the association, its benefits and its deficits. In 1995, in a large scale and statistically convincing study of 1,004 eminent individuals of the 20th century, psychiatrist Arnold Ludwig argued that no necessary or sufficient correlation, hence no causal connection, between mental illness and creative achievement was to be found. Individuals in artistic profe...

 Get Away from the Metaphorical Understanding of Meaning

Propositions are supposed to be idealizations, rather like numbers or vectors or some other abstract formulation. It looks at first very powerful, and for some purposes it’s very useful. But it takes you away from enlightenment because it gives you this false sense that you haven’t understood something really until you’ve figured out how to articulate, how to point to, how to identify the proposition that a particular meaningful event has. No. There are all kinds of meaningful events th...

 Evolutionary History Through Macro and Micro Observations

Everything in the cosmos has a history. The old dichotomy between the "historical" sciences (like geology, paleontology and evolutionary biology) and the (for want of a better term) "functional" sciences (like physics and chemistry—some would call them the "real sciences") was always supposed to be that fields like physics study dynamic processes and discover immutable laws of interaction among particles composing the cosmos—while the historical sciences study, well, history—the suppose...

 Discussion Rhythm to Promote Student Participation

Teachers are partnering with students to establish a new rhythm in classroom questioning. This rhythm provides teachers and students with a silence for thinking at two crucial junctions in the questioning process: • Wait Time 1: After a question is posed but before a student is called on to answer. • Wait Time 2: Directly following that student’s response. Almost 50 years ago, Mary Budd Rowe (1969) famously discovered multiple benefits associated with intentionally pausing at these tw...

 Ikigai and Mortality

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 inconclusive. Methods: The Ohsaki Study, a prospective cohort study, was initiated on 43,391 Japanese adults. To assess if the subjects found a sense of ikigai, they were asked the que...

 Nicotinamide riboside (NR) Increases NADP

In the first controlled clinical trial of nicotinamide riboside (NR), a newly discovered form of Vitamin B3, researchers have shown that the compound is safe for humans and increases levels of a cell metabolite that is critical for cellular energy production and protection against stress and DNA damage. Studies in mice have shown that boosting the levels of this cell metabolite—known as NAD —can produce multiple health benefits, including resistance to weight gain, improved control of bl...

 The Propagation of "Brute Men"

Many thousands of other quasi-human worlds, besides those of the "Echinoderm" type, came to an untimely end. One, which succumbed to a curious disaster, perhaps deserves brief notice. Here we found a race of very human kind. When its civilization had reached a stage and character much like our own, a stage in which the ideals of the masses are without the guidance of any well-established tradition, and in which natural science is enslaved to individualistic industry, biologists discovered the...

 The Need for Science-Based Organization

Some time shortly after the invention of the graphical Internet, it became ripely apparent that humanity was fucking itself with its own technology and was on the fast path toward societal morbidity. We maximized energy extraction without perfecting clean use, accelerated manufacturing technologies and global supply chains without developing socioeconomic models to cope with the disruptions, and modified life itself without having any perspective on what modifications would actually, in the ...
