Herschel Spectroscopy of Future Supernova 21

Posted by Soulskill from the that's-a-big-star dept.
davecl writes "ESA's Herschel Space Telescope has released its first spectroscopic results. These include observations of VYCMa, a star 50 times as massive as the sun and soon to become a supernova, as well as a nearby galaxy, more distant colliding starburst galaxies and a comet in our own solar system. The spectra show more lines than have ever been seen in these objects in the far-infrared and will allow astronomers to work out the detailed chemistry and physics behind star and planet formation as well as the last stages of stellar evolution before VYCMa's eventual collapse into a supernova. More coverage is available at the Herschel Mission Blog, which I run."

Submission + - smartphones are a goldmine for thieves (smh.com.au)

While many mobile-phone SIM cards might contain contacts and texts deleted from years ago, experts agree that it is the vastly improved data and storage capacity of the new generation of smartphones that presents the most potent risk to their owners, especially if they are lost, stolen, or disposed of carelessly.

It may not be what's recoverable from the phone that is valuable but what can be further discovered online, or by ringing around.With geospatial mapping capabilities now becoming commonplace in smartphones, photos often also contain the GPS co-ordinates of the phone as well as date and time stamp.

Although most criminals do not have ready access to the tools required to reveal this data, experts agree that times are changing. Low-end analysis devices are already available on the open market and hackers are busy creating viruses to exploit holes in the security of smartphone operating systems.

For those concerned about data security issues, getting rid of a phone or SIM at the end of its life can represent quite a dilemma. It is recommended to destroy the SIM card (taking care to cut through the chip) and remove memory cards before disposing of the phone, and handing them over only to highly reputable recyclers.

Submission + - Who's Killing The Electric Car Again? (gas2.org)

Submitted by Rei
Rei writes: Aptera Motors is an manufacturer of safe, hyper-efficient, highway-speed electric three-wheelers. Funded by Idealab, Google, and a variety of other sources, they have been working towards making (take your pick): A) one of the ugliest, or B) one of the most beautiful vehicles ever to be mass produced. When they started accepting pre-orders, over 4,000 people from California alone came running with $500 deposits. However, in recent days, the company seems to be imploding, where in the middle of wave after wave of layoffs, disastrous information keeps leaking out. Among the examples: the company's CFO, Laura Marion, was cited by the SEC in 2006 for running an Enron-style accounting scam at Delphi.

Michiel Roos writes: "At this week's OpenSource World, a Dell executive reportedly said the company's Linux netbook returns are roughly equivalent to those for Windows-based netbooks. The remarks were in response to Microsoft's COO Kevin Turner, who gave a recent speech claiming Linux netbook returns were four or five times higher."

Submission + - Reflectivity Reaches a New Low

Submitted by
sporkme
sporkme writes: "A new nanocoating material developed by a team of researchers from Rensselaer Polytechnic Institute has the lowest level of reflectivity ever seen, or not seen in this case. The amount of light reflected by the composite of silica nanorods and aluminum nitride is almost the same amount reflected by air. From the article:

Schubert and his coworkers have created a material with a refractive index of 1.05, which is extremely close to the refractive index of air and the lowest ever reported. Window glass, for comparison, has a refractive index of about 1.45.
. . .
Using a technique called oblique angle deposition, the researchers deposited silica nanorods at an angle of precisely 45 degrees on top of a thin film of aluminum nitride, which is a semiconducting material used in advanced light-emitting diodes (LEDs). From the side, the films look much like the cross section of a piece of lawn turf with the blades slightly flattened.
Suggested applications include increased efficiency in solar cells, more energy-efficient lighting and advances in quantum mechanics. No word yet on invisibility cloaks."

Submission + - Martian Global Warming?

Submitted by Anonymous Coward
An anonymous reader writes: A Russian scientist believes that global warming on Earth may be caused by the Sun and cites warming on Mars as evidence:

Habibullo Abdussamatov, head of the St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun. "The long-term increase in solar irradiance is heating both Earth and Mars," he said.

peterdaly writes: "MythTV is open source media center software that runs on Linux. Although it's powerful, it can be very difficult to install yourself. KnoppMyth and MythDora are Linux distributions that aim to automate the installation of linux and MythTV. Here are screencasts of the KnoppMyth and MythDora install process. There have been claims that the current version of KnoppMyth can be installed on fast hardware in as little as 10 minutes. MythTV is an excellent open source alternative to the DVRs offered by cable companies, Windows Media Center, or Tivo."

Russian Art writes: "BusinessWeek is reporting that it looks like Google is closer to to being able to offer full book search but finding partners for their Books search/download business is not easy — after all, who wants to curl up with a laptop? A quote from the article "Perhaps the biggest hurdle is consumer taste. Consumers are most interested in buying digital titles of books that have information they want to search for or reference, says Kessel. They are less interested in getting page-turners online, says Schroeder, adding that people want to curl up with a book, not the same computer screen they have been staring at during work all day." Does Slashdot agree?"

Submission + - How Jobs blew the iPhone keynote

Submitted by
PetManimal
PetManimal writes: "Mike Elgan, writing for Computerworld, slams Steve Jobs' keynote at MacWorld announcing the iPhone, claiming that Jobs is raising his customers' and Wall Street expectations too high, and is giving his competitors too much advance notice. And he questions the functionality of the product, noting that unlike most smart phones, the iPhone doesn't have a replacable battery, support for removable storage, or support for Microsoft apps like Word and Outlook, and can't handle voice-dialing, 3G Internet access, one-handed operation, or video recording. His conclusion:
A June unveiling that coincided with the actual product launch would have kept customers and Wall Street expectations in line; concealed product details from competitors; given Apple TV the full spotlight when it ships; kept iPod sales robust and would have helped Apple gracefully negotiate the rights to use the name "iPhone." In short, it would have been the traditional Apple home run. Steve Jobs blew it.
