As the line between science and policy sharpens in many countries, Nature highlights the importance of supporting exploratory science as a driver of long-term innovation.

Don’t deprioritize curiosity-driven research

Around the world, governments are demanding that research funding follow broader political priorities. They should be careful what they wish for.

What Are Lie Groups? | Quanta Magazine

By combining the language of groups with that of geometry and linear algebra, Marius Sophus Lie created one of math’s most powerful tools.

Amid cuts to basic research, #NewZealand scraps all support for #socialsciences https://www.science.org/content/article/amid-cuts-basic-research-new-zealand-scraps-all-support-social-sciences

"[...] the country’s center-right coalition government said it would divert half of the NZ$75 million #MarsdenFund, the nation’s sole funding source for #fundamentalscience, to “research with #economic benefits.” Moreover, the fund would no longer support any social sciences and #humanities #research, and the expert panels considering these proposals would be disbanded." 🤦‍♂️

#CMSPaper 1218: Are there bumps in the jet-photon spectrum? This would happen if there are quarks that are not elementary, new undiscovered quarks, or if microscopic #BlackHoles were produced. We in the @CMSexperiment don't see any in the 2016 through 2018 (Run2) LHC data.

Search for resonances in events with photon and jet final states in proton-proton collisions at $sqrt{s}$ = 13 TeV

A search for resonances in events with the $γ$+jet final state has been performed using proton-proton collision data collected at $\sqrt{s}$ = 13 TeV by the CMS experiment at the LHC. The total data analyzed correspond to an integrated luminosity of 138 fb$^{-1}$. Models of excited quarks and quantum black holes are considered. Using a wide-jet reconstruction for the candidate jet, the $γ$+jet invariant mass spectrum measured in data is examined for the presence of resonances over the standard model continuum background. The background is estimated by fitting the mass distribution with a functional form. The data exhibit no statistically significant deviations from the expected standard model background. Exclusion limits at 95% confidence level on the resonance mass and other parameters are set. Excited light-flavor quarks (excited bottom quarks) are excluded up to a mass of 6.0 (3.8) TeV. Quantum black hole production is excluded for masses up to 7.5 (5.2) TeV in the Arkani-Hamed-Dimopoulos-Dvali (Randall-Sundrum) model. These lower mass bounds are the most stringent to date among those obtained in the $γ$+jet final state.
