Possible role of human ribonuclease dicer in the regulation of R loops

open access: yesFEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Black Hole Production at LHC: String Balls and Black Holes from pp and Lead-lead Collisions

open access: yes, 2002
If the fundamental planck scale is near a TeV, then parton collisions with high enough center-of-mass energy should produce black holes. The production rate for such black holes at LHC has been extensively studied for the case of a proton-proton ...

Evaluation of car accident parameters during collision

open access: yesTransport, 2002
According to he literature source [5], almost 47–52% from all carcrashes make collisions of cars. So it is possible to conclude that almost each second a carcrash is a collision.
