Alternative medicine has proven tricky to study, and sometimes dangerous to patients. Doctors are divided as to whether or not it has any merit at all.
At the I/O developers conference this week, Google rolled out a Spotify-like music platform called All Access.
The NASA/ESA Hubble Space Telescope has produced the most detailed observations ever of the Ring Nebula (Messier 57). This image reveals intricate structure only hinted at in previous observations, and has allowed scientists to construct a model of the nebula in 3D - showing the true shape of this striking object.
Astronomers have found a rare encounter between two massive and gas-rich galaxies in a survey from Herschel. The event took place when the Universe was only about three billion years old and involved two galaxies forming stars with exceptional efficiency whilst in the process of merging. This galactic collision would go on to form a very massive elliptical galaxy with hardly any star formation activity. The discovery suggests a viable mechanism for the origin of the puzzling 'red and dead' galaxies that are seen in the young Universe.
What heats gas near supermassive black holes at the centre of galaxies? Astronomers have looked at the centre of our Galaxy, the Milky Way, with ESA's Herschel Space Observatory and discovered a rich variety of molecules at surprisingly high temperatures - up to 1000 K. The new data suggest that the molecular gas is heated up by shocks, in addition to ultraviolet radiation from massive stars close to the Galactic Centre. Shocks develop in the gas as the material surges towards Sagittarius A*, the region harbouring the supermassive black hole at the heart of the Milky Way.
For the first time, scientists have resolved the detailed structure of the core region where magnetic reconnection takes place in the magnetosphere of Earth using unprecedented wave measurements. The study, based on data from ESA's Cluster mission, has mapped different types of electrostatic waves in this region. The waves trace populations of plasma particles that are involved in the different stages of a magnetic reconnection event.
Report for the period 6 January to 2 February 2013
This reporting period covers four weeks of Venus Express operations, from 6 January to 2 February 2013, and includes the continuation of the fourteenth occultation season, the start of the twenty-third eclipse season, and start of the Venus surface imaging campaign.
Report for period 5 to 27 February 2013
Mission operations of the Herschel space observatory continued nominally during the reporting period, with the spacecraft and subsystems all performing as expected.
Report for period 6 December 2012 to 4 February 2013Mission operations of the Herschel space observatory continued nominally during the reporting period, with the spacecraft and subsystems all performing as expected.
Report for the period 9 December 2012 to 5 January 2013
This reporting period covers four weeks of Venus Express operations, including the start of the fourteenth occultation season, end of the tenth Atmospheric Drag Experiment campaign, and pericentre altitude raising using four orbit correction manoeuvres.
Report for the period 6 to 14 June 2011This report covers nine days of Rosetta mission operations. The main activities were the spin-up of the spacecraft and entry into deep-space hibernation mode. The spacecraft will remain in this state until 20 January 2014 when the hibernation exit sequence will be initiated. The next Rosetta status report will be issued towards the end of January 2014.
The Director of Science and Robotic Exploration intends to define, in the course of 2013, the science themes and questions that will be addressed by the next two Large (L-class) missions in the Cosmic Vision 2015-2025 plan, "L2" and "L3", currently planned for a launch in 2028 and 2034, respectively. This process starts with a consultation of the broad scientific community, in the form of the current Call, soliciting White Papers to propose science themes and associated questions that the L2 and L3 missions should address. The submission deadline for White Papers is 24 May 2013, 12:00 CEST (noon).
U.S. officials approve project, which is taking advanced measures to keep turbines from harming condors. Earlier, Terra-Gen was told it would not be prosecuted if a condor is accidentally killed.
MOJAVE, Calif. — Randy Hoyle strode proudly this week along a wind-swept expanse of sand, sage and juniper in the Tehachapi Mountains that will soon bristle with antennas and listening devices designed to protect endangered California condors.

WASHINGTON (Reuters) - Saddled with Middle East problems ranging from Iran to Syria and beyond, President Barack Obama now faces one that is both old and new: Iraq.
The 5.7 temblor northeast of Sacramento, in a part of the state that hasn't been studied much, didn't do a lot of damage but was felt 'along an unusual distance.'
A magnitude 5.7 temblor Thursday night was the largest earthquake to shake California since 2008 and has generated curiosity from seismologists.
Populations of frogs and other amphibians are declining at an average rate of 3.7 percent each year, according to a new U.S. Geological Survey study.
PHOENIX (Reuters) - Arizona lawman Joe Arpaio violated the constitutional rights of Latino drivers in his crackdown on illegal immigration, a federal judge found on Friday, and ordered him to stop using race as a factor in law enforcement decisions.
ISTANBUL - Syrian opposition talks aimed at presenting a coherent front at an international peace conference to end the civil war faced the prospect of collapse after President Bashar al-Assad's foes failed to cut an internal deal, opposition sources said on Friday.
