While this was a 4. A Tom Gauld cartoon appears on the Letters page. Readers contribute observations on examples of pseudoscience to Feedback, and offer questions and answers on scientific and technical topics to Last Word. New Scientist has produced a series of books compiled from contributions to Last Word. From issue of 4 May New Scientist introduced a new look, with a "slightly updated design, with A dedicated "Views" section was added between news reports and in-depth features, including readers' letters, comment, and reviews on science, culture and society.
Regular columnists were introduced, and columns in the culture pages. Since New Scientist has held an annual science festival in London.
Styled New Scientist Live , the event has attracted high-profile scientists and science presenters. In September , New Scientist was criticised by science fiction writer Greg Egan , who wrote that "a sensationalist bent and a lack of basic knowledge by its writers" was making the magazine's coverage sufficiently unreliable "to constitute a real threat to the public understanding of science".
In particular, Egan found himself "gobsmacked by the level of scientific illiteracy" in the magazine's coverage  of Roger Shawyer's " electromagnetic drive ", where New Scientist allowed the publication of "meaningless double-talk" designed to bypass a fatal objection to Shawyer's proposed space drive, namely that it violates the law of conservation of momentum.
Egan urged others to write to New Scientist and pressure the magazine to raise its standards, instead of "squandering the opportunity that the magazine's circulation and prestige provides". In January , New Scientist ran a cover with the title " Darwin was wrong". Some evolutionary biologists who actively oppose the intelligent design movement thought the cover was both sensationalist and damaging to the scientific community.

Phylogenies are typically used in evolutionary biology: In any species, the DNA sequences of one generation are copied to the next generation just as your parents' DNA was copied to your DNA.
A population or species through time is called a "lineage.
This is evolution: "descent with modification," as Darwin put it. When a lineage splits — one population becomes two — then the new populations can evolve independently.
In biology, this is called "speciation. Not all phylogenies are based on DNA. Some studies use fossils and "coded characters" that describe the shape and characteristics of the fossils. For example, absence or presence of a tail might be coded as 0 or 1.
What's different about the phylogeny in this paper? Splitting events on this phylogeny represent production of a new version of a bill. The "tips" of the tree represent the dates of the actual published versions in state legislatures.
How do I read a phylogeny? What's the big deal about "direct ancestors?
Does inference of direct ancestors mean that we will start to see scientific papers claiming that fossil species X is a direct ancestor of living species Y? But keep in mind that the methods are new. In the case of bill texts, the entire history has gone on during human lifetimes although some of it may have been hidden from public view , and we think that we have all of the bills that were published in legislative sessions.
The case of fossils is much more complicated, because we usually don't think we have collected all of the fossil species that existed, and because there are many biases in where fossils get preserved and discovered.
Still, in "ideal" situations, we may be able to detect direct ancestors with high confidence. The statement "high confidence" is key.

These phylogenetic methods are Bayesian, which means they assign probabilities to hypotheses. What's phylomemetics? The term "meme" was invented by Richard Dawkins in the s The Selfish Gene, , and refers to a cultural object that gets copied and modified in the culture.Namespaces Article Talk.
The Physics of Free Will. The Grimbledon Down comic strip, by cartoonist Bill Tidy , appeared from to Science magazine. At the other extreme, an overemphasis on quantity is also problematic because accepting less scientific rigor in statistics, replication, and quality controls or a less rigorous review process would produce a very high number of articles, but after considering costly setbacks associated with a high error rate, true progress would also be low.
I work on several theoretical and observational projects to devise and implement fun experiments that leverage cosmology to test fundamental physics, including novel tests of quantum theory with astronomical observations as well as Infrared and Optical studies of Supernovae with ground and space based telescopes to measure the expansion history of the universe, cosmic acceleration, and dark energy.
