Subatomic particle seen changing to antiparticle and back for the first time
Physicists have proved that a subatomic particle can switch into its antiparticle alter-ego and back again, in a new discovery revealed today. An extraordinarily precise measurement made by Oxford researchers using the LHCb experiment at CERN has provided the first evidence that charm mesons can change into their…

Tianwen-1 attitude in Mars orbit
It has been a while since the last time I wrote an update about Tianwen-1’s attitude . In that post I showed that Tianwen-1 had changed to a sun angle of 0 degrees with respect to the spacecraft’s X axis on 2020-10-22. Since then, nothing changed, even after the spacecraft arrived to Mars orbit on February 2021, so I…

Peer review is an honor-based system (2008)
It would take too long to expose all of the flaws of peer review, here are some: some work is just flat wrong because the reviewers cannot analyze all of the mathematical results, and because they cannot redo the experiments; numerous researchers cheat, sometimes in small ways ("2 out of 3 experiments agree with by ……

Palm oil favors tumor expansion
Ninety per cent of cancer deaths are caused by metastasis, that is to say, the spread of the primary tumour to other organs. Scientists led by ICREA researcher Dr. Salvador Aznar-Benitah at IRB Barcelona have described the mechanism by which a diet rich in palmitic acid makes tumour cells more aggressive, conferring…

Influenza A (H1N1) – How many bits does it take to kill a human? (2009)
I read a fantastic article in Nature magazine (vol 459, pp931-939 (18 June 2009)) that summarizes not only the current state of novel H1N1 (aka Swine Flu) understanding, but also a compares H1N1 against other flu strains. In particular, it discusses in-depth how the pathogenic components — i.e., the stuff that kills…
