Naming things. The anxiety of the "most evolved"...
Contradicting earlier claims, "The Family That Walks on All Fours," a group of quadrupedal humans made famous by a 2006 BBC documentary, have simply adapted to their inability to walk upright and do not represent an example of backward evolution, according to new research by Liza Shapiro, an anthropologist at The University of Texas at…

1+2+3+… = -1/12 !? Or... "Why infinity does not exist!"
Srinivasa Ramanujan presented two derivations of "1 + 2 + 3 + 4 + ... = −1/12" in chapter 8 of his first notebook. The simpler, less rigorous derivation proceeds in two steps, as follows. The first key insight is that the series of positive numbers 1 + 2 + 3 + 4 + ·…

Magnetic fields. Everywhere...
The first set of high-resolution results from ESA's three-satellite Swarm constellation reveals the most recent changes in the magnetic field that protects our planet. Launched in November 2013, Swarm is providing unprecedented insights into the complex workings of Earth's magnetic field, which safeguards us from the bombarding cosmic radiation and charged particles. Measurements made over the…

Asexual reproduction - The menace to ToE...
Plants can transfer their entire genetic material to a partner in an asexual manner, researchers report. Occasionally, two different plant species interbreed with each other in nature. This usually causes problems since the genetic information of both parents does not match. But sometimes, instead of passing on only half of each parent's genetic material, both…

Excitons... Parmenidions... Exciting!
Getting excited can kick a person’s energy to a higher level. At the nanoscale, strange almost-particles called excitons do the same trick. In a crystal, thin film or even some liquids, an incoming particle of light can slam into an electron, bumping it to a higher energy level and leaving a hole at the energy…
