Microscopic steam engines new world’s smallest

How small are Dr. Pedro A. Quinto-Su’s steam engines? Smaller than red blood cells and most bacteria–between one and three millionths of a meter. The significantly strong pistons are powered by a combined process of optical manipulation which bypasses microfabrication and draws strength from simplicity, taking scientists one step closer to the “lab on a … Read more

Memories are stored in neurons, not synapses, and therefore can be restored, shows new research

Does the entire library of memories stored throughout our lifetime remain dormant within our minds, and can these memories be restored? New research has led UCLA neurobiologists to conclude that the storage mechanism for memories is actually independent of synaptic change–the mechanism that mediates the expression of memories. Rather, memories are stored in persistent epigenetic … Read more

What causes cell division? Neither of the prevailing theories, but rather an extraordinarily simple quantitative principle of cell-size control, according to UC San Diego scientists

How do cells control their size? What causes them to divide? Contrary to what many biologists have expected, evidence supporting an answer to one of the most fundamental and longstanding problems of biology has been accomplished by UC San Diego researchers. The study surprised even the researchers: a simple quantitative principle explains the phenomena without … Read more

Small farmers produce 80% percent of the world’s food, and the do it with less than 25% of the world’s farmland – study

The share of farmland tended by small farmers is shrinking. The land is changing hands. Although small farms are more productive than large farms and tend to grow food products–they produce 80 percent of the world’s food–they are being swallowed up by large corporate farms that grow high-profit crops for export markets. The land left … Read more

Statistically, NYPD shoot at blacks seven times as often as at whites – statistically, over seven times as many blacks shoot at NYPD than whites

Statistically, New York police shoot more often at blacks than at whites–by about 700 percent. But, statistically blacks are armed and shoot at police more often than whites–by over 700 percent, according to national statistics and the NYPD’s annual firearms discharge report. In light of the recent “Black Lives Matter” protests in New York following the decision not to indict white … Read more

With English comes great power, and responsibility – new study maps global language potency

Language facilitates the global flow of ideas, and elite languages in global communications are those that are both literate and online, according to new research that has mapped information flows across languages. Certain languages have been found to be much more powerful than others, because they are more and better connected within the communications networks of the … Read more

The mind has many rooms – their architecture is the architecture of memory – study

Memory was considered the greatest faculty of mind before the invention of printing. Greek philosophers, Roman lawyers and Medieval European priests practiced the art by storing memories within mentally constructed architecture and objects. Recently, a study has found that rooms may be just how memory is stored. “Each place–or room in your house–is represented by … Read more
