The rate of descent did not slow as much as expected,
and the spacecraft probably made a hard landing.
The laser instrument that measured how high Resilience was above the surface was slow in making its measurements,
which may have contributed to the problem.
“At this point, we do not know clearly about the cause,”
Takeshi Hakamada, the chief executive of Ispace, said in translated remarks.
The loss of the second mission could lead NASA to rethink its pla…

Ispace of Japan’s Moon Lander Resilience Has Crashed
The loss of the Resilience spacecraft by Ispace repeated a crash into the moon in 2023 of the company’s first robotic lunar landing mission.

Symmetry-protected electronic metastability in an optically driven cuprate ladder
Optically excited quantum materials exhibit nonequilibrium states with remarkable emergent properties, but these phenomena are usually transient, decaying on picosecond timescales and limiting practical applications. Advancing the design and control of nonequilibrium phases requires the development of targeted strategies to achieve long-lived, metastable phases. Here, we report the discovery of symmetry-protected electronic metastability in the model cuprate ladder Sr$_{14}$Cu$_{24}$O$_{41}$. U…

Scaling Laws of Quantum Information Lifetime in Monitored Quantum Dynamics
Quantum information is typically fragile under measurement and environmental coupling. Remarkably, we find that its lifetime can scale exponentially with system size when the environment is continuously monitored via mid-circuit measurements -- regardless of bath size. Starting from a maximally entangled state with a reference, we analytically prove this exponential scaling for typical Haar random unitaries and confirm it through numerical simulations in both Haar-random and chaotic Hamiltonian…

Confinement-induced proliferation of vortices around marine invertebrate larvae
The ocean is teeming with a myriad of mm-sized invertebrate planktonic larvae, which thrive in a viscous fluid environment. Many of them rely on ciliary beating to generate fluid flows for locomotion and feeding. Their larval forms, local morphologies, and ciliation patterns exhibit remarkable diversity, producing intricate and dynamic 3D flows that are notoriously difficult to characterize in laboratory settings. Traditional microscopic imaging techniques typically involve gently squeeze-confi…

Interpreting nebular emission lines in the high-redshift Universe
One of the most remarkable outcomes from JWST has been the exquisite UV-optical spectroscopic data for galaxies in the high-redshift Universe ($z \geq 5$), enabling the use of various nebular emission lines to infer conditions of the interstellar medium. In this work, we evaluate the reliability of these diagnostics, specifically those used to recover the star formation rate (SFR), the ionising photon production efficiency, and the gas-phase oxygen abundance. We use forward-modelled galaxy spec…

I got this post by @… in my email today, it was forwarded while it still was attributed to Liz Cheney with this preface which I agree with:
"When she was in Congress, I disagreed with almost everything she said and every vote she made. But on the transcendent issue of our time — protecting our democracy from Trump and the forces of authoritarianism and fascism — Liz Cheney has been correct, clear, and courageous."
Turns out the message is not by Liz Cheney but is well worth reading as a kick in the ass to the Democratic Party.

Sorry to miss it in person and that I cannot stay for the panels on: teacher, gender, inclusion, decolonisation, and future action. Lovely to see and hear so many wonderful colleagues even from a distance.
My fun memory was the cartoon by the talented (then PhD student) Kalifa Damani during my talk on silent exclusion at the REAL Centre in January 2020 before the world shut, and many fun moments with Pauline Rose over the years.
Congratulations! The achievements are remarkable.

Seeking a distraction from his current political travails,
Donald Trump is attempting to relitigate the nearly decade-old controversy over Russian involvement in the 2016 election.
Trump claims that President Barack Obama committed treason,
-- a crime that may be punishable by death.
Trump is wrong on the facts and the law,
and his sensational allegation serves only to demonstrate how completely he has degraded contemporary political discourse.

Opinion | The Line Trump Crossed by Accusing Obama of Treason
President Trump’s history of intemperate remarks has earned him a perverse kind of immunity; the more outrageous his statement, the faster it is often dismissed.
