Doing the right thing: Particle physicists pull paper after equation collides with the truth

with 4 comments

physicalreviewlettersThree physicists at Imperial College London have retracted a paper on Coulomb collisions, a kind of fender bender between two charged particles, after realizing their equations were written wrong.

The mistake resulted in an erroneous conclusion about the strength of the collisions.

Here’s the notice for “Effects of Large-Angle Coulomb Collisions on Inertial Confinement Fusion Plasmas”: Read the rest of this entry »

Downstream effects: Comment on retracted narcolepsy paper retracted

leave a comment »

stmcoverThe recent retraction of a paper in Science Translational Medicine reporting “one of the biggest things to happen” in narcolepsy research has claimed a bystander: A letter that commented on the no-longer-landmark article.

The authors of the letter are with GlaxoSmithKline’s vaccine division. Here’s the new notice: Read the rest of this entry »

Publisher updates with more info on staph retraction

with 2 comments

cidWe brought you this story last week, about a paper on drug resistant staph being retracted for a lab error. Now, we’ve got an update from Rachel Safer, senior editor for medical journals at Oxford University Press, where the paper was published.

Apparently, the researchers “inadvertently relied upon the use of a test system that was not approved for the microorganism studied in their paper,” leading to the retraction, and the corresponding author of the study wasn’t initially all that responsive:

87% of bugs resistant to antibiotics? Not so fast, as staph paper yanked after staff mistake

with 3 comments

What could have been a truly scary study about drug resistant staph infections in hospitals has been retracted due to a lab error.

6.coverResearchers at a community hospital in Pittsburgh claimed that the commonly quoted 3% rate of staph that is resistant to ceftriaxone and sensitive to methicillin was drastically understated. However, an “honest error in the interpretation of a key lab test” called the findings into question.

Here’s the abstract: Read the rest of this entry »

Authors ask Science to retract Hayabusa asteroid paper

with 13 comments

jaxa_logoThe Japan Aerospace Exploration Agency (JAXA) has requested that Science retract a 2006 paper about the makeup of asteroid Itokawa as observed from the spacecraft Hayabusa, the news section of Science reports.

Instead of calibrating their equipment on Earth, the scientists assumed they’d see both magnesium and silicon in the x-ray spectra, and used that assumption to assess the rest of the chemical composition of the asteroid.

The paper may be based on faulty assumptions, but the conclusions have been backed up by other published papers, according to the Science magazine report: Read the rest of this entry »
