Publication Rankings

I enjoyed looking through the Nature Indexes section recently in that journal – I believe that they do this primarily as a way to make a new section in which to sell advertisements, to be honest, but the content itself is worth a look. They're tracking publications in 82 leading scientific journals and looking for trends in publication frequency, etc. Some of the results are not particularly surp

Sixth right whale death in Canadian waters sets researchers on urgent mission for solutions

There is a growing urgency to identify where endangered North Atlantic right whales are migrating, say researchers after a sixth dead mammal was discovered in the Gulf of St. Lawrence.

How historic Jupiter comet impact led to planetary defense

Twenty-five years ago, humanity first witnessed a collision between a comet and a planet. From July 16 to 22, 1994, enormous pieces of the comet Shoemaker-Levy 9 (SL9), discovered just a year prior, crashed into Jupiter over several days, creating huge, dark scars in the planet's atmosphere and lofting superheated plumes into its stratosphere.

Researchers at the University of Southampton and the Korea Institute for Advanced Study have recently showed that supersymmetry is anomalous in N=1 superconformal quantum field theories (SCFTs) with an anomalous R symmetry. The anomaly described in their paper, published in Physical Review Letters, was previously observed in holographic SCFTs at strong coupling, yet their work confirms that it is

An innovative method for detecting defaulting participants based on sparse reconstruction

In the contract-based demand response, some of the participants may default in providing the scheduled negawatt energy owing to demand-side fluctuations faults. Thus, the detection of defaulting participants is an important function of the aggregator. A group of Japanese researchers has developed a method to detect defaulting participants based on sparse reconstruction. This enables assured detect

Imitation breeds war in new evolutionary theory

When anthropologists consider the origins of warfare, their evolutionary theories tend to boil it down to the resource-scarcity trifecta of food, territory and mates—three resources that would justify the loss of life and risk to a warring group of hunter-gatherers.

Space weather causes years of radiation damage to satellites using electric propulsion

The use of electric propulsion for raising satellites into geostationary orbit can result in significant solar cell degradation according to a new study. The extended journey results in greater exposure to the damaging effects of space weather. Understanding the size of this risk is essential for commercial operators to take steps to mitigate the effects and protect their assets.

Study results pave the way to programmable electronic inks

Conjugated polymers are important materials because of their special electronic and optical properties and low cost, making them very promising for a wide range of applications.

Science is about natural law, while religion is about ethics. As long as you keep these two separate, Kaku says, there's no problem at all. Problems arise, however, when the natural sciences begin to "pontificate upon ethics" and when religious people begin to pontificate about natural law.

Why is the Earth's F/Cl ratio not chondritic?

It is generally believed that terrestrial planets were made from chondrites. However, geochemical observations have shown that the abundance pattern of volatile elements, such as fluorine and chorine in the Earth is inconsistent with chondrites. New high-pressure experiments on the silicate mineral-melt partitioning of F and Cl suggest that F and Cl fractionation during magma ocean crystallization

How shiny are near-Earth objects?

Near-Earth objects (NEOs) are small solar system bodies whose orbits sometimes bring them close to the Earth.

Most meteorites for example, one of the key sources of knowledge about the earl

Why is the Earth's F/Cl ratio not chondritic?

Primitive chondrites, un-molten stony meteorites, are believed to be the building blocks of the Earth. Because terrestrial planets have experienced chemical differentiation in the core, mantle, and hydrosphere, the elemental abundance pattern of some elements at the planetary surface is not chondritic. In other words, the non-chondritic abundance pattern of elements on the planetary surface is a k

A Surprising Idea About the Risks of Extinction

Isle Royale is 200 square miles of land in the watery expanse of Lake Superior. One cold winter 70 years ago, wolves came over an ice bridge and settled into a largely isolated island existence. Unfortunately, island life has not been good for them. By 2016 , the number of wolves on Isle Royale declined from a peak of 50 to just two, a male and a female. As a result of inbreeding, they were half-
