Clinical Implications of Aberrant Retinoblastoma Signaling in Patients With Grade 4 IDH-Mutant AstrocytomaA Retrospective Cohort Study

Background and ObjectivesThe data on the prognostic factors of grade 4 isocitrate dehydrogenase (IDH)–mutant astrocytoma remain limited since the 2021 update of the World Health Organization classification of CNS tumors. This study aimed to investigate…

Ireland recalls almost 13,000 passports over missing ‘IRL’ code

Ireland’s Department of Foreign Affairs has recalled nearly 13,000 passports after a software update caused a printing defect.

The printing error makes the documents non-compliant with international travel standards and potentially unreadable at automated border gates.

Tetraquark measurements could shed more light on the strong nuclear force

Identifying and studying tetraquarks and pentaquarks helps physicists to better understand how the strong force binds quarks together. This force also binds protons and neutrons in atomic nuclei.

Physicists are still divided as to the nature of these exotic hadrons. Some models suggest that their quarks are tightly bound via the strong force, so making these hadrons compact objects. Others say that the quarks are only loosely bound. To confuse things further, there is evidence that in some exotic hadrons, the quarks might be both tightly and loosely bound at the same time.

Now, new findings from the CMS Collaboration suggest that tetraquarks are tightly bound, but they do not completely rule out other models.

The Many Worlds of the Quantum Multiverse

Decoherance which is why we are not aware of the universe splitting.


Is our universe a definitive single reality or is it merely one within an infinitely branching multiverse? Be sure to check out Physics Girl’s Dianna Cowern for more awesome science / physicsgirl.

The many worlds theory proposes that the wavefunction never actually collapses. The observer simply follows one of those many possible paths into their present reality while all the other paths continue on independent of the observer. Each of these paths branches off into an entirely different reality. In this episode Matt discusses the details of the many worlds theory and why it’s not so far-fetched to think that our reality is simply one of an infinite number of realities existing within space time.
