With the delicate economical situation that many developed countries are experiencing in the last years, a significant number of questions and concerns have been risen about how to properly assign and distribute funding to scientific institutions and research group leaders. In particular, a relevant question for science funding could be how to optimize the scientific […]

Ocean health imperiled thrice over Climate change and increases in oxygen-free “dead zones” and acidification each pose health concerns for the world’s oceans, with immediate action required, says a report from the International Programme on the State of the Ocean. BBC Bulk of Earth’s xenon concealed in planet’s core Earth’s atmosphere appears to have only […]

19 elements to have atomic weights adjusted Aluminum, cadmium, gold and arsenic are among 19 elements that are having their atomic weights adjusted by the International Union of Pure and Applied Chemistry. More precise measurements are now available leading to the new weight calculations, which happens rarely. The atomic weight of nonmetal selenium hasn’t been […]

PET helps ID tau protein in the brain PET shows promise in detecting tau protein accumulation in the brain, according to a study in the journal Neuron. Researchers developed a chemical that binds with the substance and used PET to identify areas of the brain at risk of neuronal death. The approach was evaluated in […]

Reprogrammed stem cells in mice could pave way to tissue regeneration Spanish scientists successfully forced mature cells into an embryonic-like state inside the bodies of living mice, creating so-called reprogrammed induced pluripotent stem cells. Transforming mature cells into stem-like cells “means turning back the clock when everything in the environment favors the opposite,” lead author […]

We saw at the end of the first entry of this series that, in spite of the adjective ‘true’ seeming to be semantically redundant in the sense of its role being equivalent to just assert exactly the same assertion to which it is applied, it is nevertheless grammatically non-redundant, in the sense that there are […]

The relevance of demand factors for explaining growth was stated almost simultaneously by Michal Kalecki and John Maynard Keynes in the 1930s. The main conclusion of the theory of effective demand is that spending determines income. Keynes stated that the marginal propensity to consume decreases when total income growths. Kalecki considered different propensities to consume […]

Hypersonic flight to undergo further study The U.S. Air Force and the Defense Advanced Research Project Agency are joining forces to study the capabilities of hypersonic flight. The project will build on the Air Force’s X-51A Waverider program, which ended in May when the unmanned craft reached a top speed of Mach 5.1 riding on […]

Quantum mechanics and relativity constitute the two main revolutions in physics on the twentieth century. Furthermore, the counterintuitive character of quantum mechanics yields to a rich branch of different possible interpretations, and there are still many open questions. Not solving, but just defining these questions, was the main purpose of a conference entitled “Quantum physics […]

Long canyon lies beneath Greenland Ice Sheet A canyon nearly twice as long as the Grand Canyon has been found under the massive Greenland Ice Sheet. By studying data compiled over three decades, Jonathan Bamber of the University of Bristol in the U.K. and his team discovered details about the canyon, which is at least […]
