Submission + - Rejected papers get more citations when eventually published (

scibri writes: In a study of more than 80,000 bioscience papers, researchers have illuminated the usually hidden flows of papers from journal to journal before publication.

Surprisingly, they found that papers published after having first been rejected elsewhere receive significantly more citations on average than ones accepted on first submission.

There were a few other surprises as well...Nature and Science publish more papers that were initially rejected elsewhere than lower-impact journals do.

So there is apparently some reason to be patient with your paper’s critics — they will do you good in the end.


Submission + - New NASA robot could help paraplegics walk (

coondoggie writes: "NASA said today it has helped develop a 57-lb robotic exoskeleton that a person could wear over his or her body either to assist or inhibit movement in leg joints. The X1 was derived from NASA and General Motors Robonaut 2 project and the could find applications as an in-space exercise machine to supply resistance against leg movement more importantly as a way to help some individuals walk for the first time."

Submission + - Sun Releasing 8-Core Niagara 2 Processor

An anonymous reader writes: Sun Microsystems is set to announce its eight-core Niagara 2 processor next week. Each core supports eight threads, so the chip handles 64 simultaneous threads, making it the centerpiece of Sun's "Throughput Computing" effort. Along with having more cores than the quads from Intel and AMD, the Niagara 2 have dual, on-chip 10G Ethernet ports with crytopgraphic capability. Sun doesn't get much processor press, because the chips are used only in its own CoolThreads servers, but Niagara 2 will probably be the fastest processor out there when its released, other than perhaps the also little-known 4-GHz IBM Power 6.

Submission + - Forensics Expert says Al-Qaeda Images Altered

WerewolfOfVulcan writes: Wired reports that researcher Neal Krawetz revealed some veeeeeery interesting things about the Al-Qaeda images that our government loves to show off.

From the article: "Krawetz was also able to determine that the writing on the banner behind al-Zawahiri's head was added to the image afterward. In the second picture above showing the results of the error level analysis, the light clusters on the image indicate areas of the image that were added or changed. The subtitles and logos in the upper right and lower left corners (IntelCenter is an organization that monitors terrorist activity and As-Sahab is the video production branch of al Qaeda) were all added at the same time, while the banner writing was added at a different time, likely around the same time that al-Zawahiri was added, Krawetz says." Why would Al-Qaeda add an IntelCenter logo to their video? Why would IntelCenter add an Al-Qaeda logo? Methinks we have bigger fish to fry than Gonzo and his fired attorneys... }:-) The article contains links to Krawetz's presentation and the source code he used to analyze the photos.

The trouble with doing something right the first time is that nobody appreciates how difficult it was.
