Video: A colorful 'landing' on Pluto

Fri, 20 Jan 2017 18:10:11 EST

What would it be like to actually land on Pluto? This movie was made from more than 100 images taken by NASA's New Horizons spacecraft over six weeks of approach and close flyby in the summer of 2015. The video offers a trip down onto the surface of Pluto—starting with a distant view of Pluto and its largest moon, Charon—and leading up to an eventual ride in for a "landing" on the shoreline of Pluto's informally named Sputnik Planitia.

Data should smash the biological myth of promiscuous males and sexually coy females

Fri, 20 Jan 2017 10:40:02 EST

That males are naturally promiscuous while females are coy and choosy is a widely held belief. Even many scientists – including some biologists, psychologists and anthropologists – tout this notion when interviewed by the media about almost any aspect of male-female differences, including in human beings. In fact, certain human behaviors such as rape, marital infidelity and some forms of domestic abuse have been portrayed as adaptive traits that evolved because males are promiscuous while females are sexually reluctant.



Seals found able to find hidden fish by using whiskers to trace aspiration currents

Fri, 20 Jan 2017 10:40:01 EST

A team of researchers with the University of Rostock in Germany has found that seals are able to use their whiskers to find fish hiding in the sand on the ocean floor. In their paper published in the Journal of Experimental Biology, the team describes experiments they carried out with seals in a near-native environment and what they learned from them.



Is part of Chelsea Manning's legacy increased surveillance?

Fri, 20 Jan 2017 10:30:01 EST

The military's most prolific leaker of digital documents has ushered in an age of even more increased surveillance over government workers. The legacy of Chelsea Manning's actions is under discussion in the wake of the announcement that the former Army private will be released from military prison in May. In one of his last official acts, President Obama commuted her sentence for violations of the Espionage Act and copying and disseminating classified information. The commutation reduced her sentence from 35 years to the seven years she has already served, plus four additional months needed to effect her release.

The evolution of massive galaxy clusters

Fri, 20 Jan 2017 09:30:14 EST

Galaxy clusters have long been recognized as important laboratories for the study of galaxy formation and evolution. The advent of the new generation of millimeter and submillimeter wave survey telescopes, like the South Pole Telescope (SPT), has made it possible to identify faint galaxy clusters over large fractions of the sky using an effect first recognized by Rashid Sunyaev and Yakov Zel'dovich in 1969: When hot electrons in the cluster gas interact with light from the ubiquitous cosmic microwave background they increase its brightness very slightly.



STO2 landed and data secured

Fri, 20 Jan 2017 09:30:01 EST

The STO2 telescope with Dutch detectors on board that circled around the South Pole in December 2016 to investigate gas clouds between the stars landed safely on 30 December.



Violations of energy conservation in the early universe may explain dark energy

Fri, 20 Jan 2017 09:30:01 EST

(Phys.org)—Physicists have proposed that violations of energy conservation in the early universe, as predicted by certain modified theories of quantum mechanics and quantum gravity, may explain the cosmological constant problem, which is sometimes referred to as "the worst theoretical prediction in the history of physics."
