Space & Earth news
A naked-eye comet invites itself to the March sky, 2013
It will appear in the West at sunset, from around the 8th to the 13th of March 2013, and will be visible to the naked eye up to the end of the month. Comet Pan-Starrs C/2011 L4 will traverse Cetus, Pisces, Pegasus and Andromeda. The scientists of the Paris Observatory are calculating its path. They have been following it since September 2012, using the large Nançay radiotelescope (in the Cher region of France), the Herschel infra-red space observatory, at the Pic-du-Midi Observatory (in the Pyrenees), and with the antennas at Bure (in the Alps), at Pico Veleta (Spain), and at Chajnantor (Chile).

Mobile aerosol observing units deployed at Cape Cod
Bracing against -10 degree Celsius temperatures in Cape Cod, Massachusetts, Brookhaven atmospheric chemist Stephen Springston and his team recently completed a one-week restaging of two portable atmospheric sampling stations used for climate studies. Part of the Department of Energy's Atmospheric Radiation Measurement (ARM) Climate Research Facility, the Mobile Aerosol Observing System (MAOS) consists of two compact, state-of-the-art instrument suites installed in modified shipping containers. The mobile units have complementary research objectives—one is specialized to conduct on-site measurements of aerosol samples, the other to examine the chemical composition of samples—and the two are deployed together.

Quiet Interlude in Solar Max
(Phys.org) —Something unexpected is happening on the Sun. 2013 was supposed to be the year of "solar maximum," the peak of the 11-year sunspot cycle. Yet 2013 has arrived and solar activity is relatively low. Sunspot numbers are well below their values from 2011, and strong solar flares have been infrequent.
Russian asteroid explosion and past impactors paint a potentially grim future for Earth
The recent meteor explosion over Chelyabinsk brought to the forefront a topic that has worried astronomers for years, namely that an impactor from space could cause widespread human fatalities. Indeed, the thousand+ injured recently in Russia was a wake-up call. Should humanity be worried about impactors? "Hell yes!" replied astronomer Neil deGrasse Tyson to CNN's F. Zakharia .

New study finds stars in metal-rich galactic areas explode more violently
(Phys.org) —A team of researchers working in China has found evidence to suggest that stars that exist in metal-rich galactic areas tend to explode more violently when they go supernova, than do stars that explode in less metal-rich areas. In their paper published in the journal Science, describing their research, the team details how after analyzing data from the remnants of 188 type 1a supernovas, they found that those stars that existed in metal-rich areas and maybe in younger systems, tended to produce more violent explosions and associated diverse spectral features.
Cassini makes last close flyby of Saturnian moon Rhea
(Phys.org) —NASA's Cassini spacecraft will be swooping close to Saturn's moon Rhea on Saturday, March 9, the last close flyby of Rhea in Cassini's mission. The primary purpose will be to probe the internal structure of the moon by measuring the gravitational pull of Rhea against the spacecraft's steady radio link to NASA's Deep Space Network here on Earth. The results will help scientists understand whether the moon is homogeneous all the way through or whether it has differentiated into the layers of core, mantle and crust.

'Bad neighbourhoods' on the internet are a real nuisance
Of the 42,000 Internet Service Providers (ISPs) surveyed, just 20 were found to be responsible for nearly half of all the internet addresses that send spam. That just is one of the striking results of an extensive study by the University of Twente's Centre for Telematics and Information Technology (CTIT). This study focused on "Bad Neighbourhoods" on the internet (which sometimes correspond to certain geographical areas) that are the source of a great deal of spam, phishing or other undesirable activity. In his thesis, Giovane Moura describes this situation in detail.

Full wired: Planar cell polarity genes guide gut neurons
The enteric nervous system (ENS), the "little brain" that resides within the gut wall, governs motility, secretion, and blood flow in the human gastrointestinal tract. Failure of the ENS to develop normally leads to congenital megacolon (Hirschsprung Disease) while loss of normal gut innervation is thought to contribute to debilitating motility disorders, such as irritable bowel syndrome. In order to prevent and treat these conditions, it is necessary to understand the molecular mechanisms that control the formation and function of the ENS.
Enhanced brain acetate metabolism may reward heavy drinkers
In addition to its well-known effects on the CNS, alcohol consumption has a significant impact on metabolism.

The t haplotype in mice—a block of linked genes occupying the proximal half of mouse chromosome 17—is one of the best-studied examples of a selfish genetic element. Through an elaborate sperm-poisoning system, heterozygous males with only one copy of the t haplotype transfer the genetic element to over 95% of their progeny, while offspring that inherit two copies of the haplotype typically die during development.
