Redefining Dementia Treatment: Berkeley Scientists Unveil Promising New Breakthrough
Research from UC Berkeley indicates that ongoing stress caused by protein aggregation is leading to the death of brain cells. Numerous neurodegenerative conditions, including Alzheimer's and Parkinson's, involve the buildup of protein clusters, known as aggregates, within the brain. This phenomenon

Florida is swamped by disease outbreaks as quackery replaces science
“The surgeon general is Ron DeSantis’s lapdog, and says whatever DeSantis wants him to say,” said Dr Robert Speth, a professor of pharmaceutical sciences at south Florida’s Nova Southeastern University with more than four decades of research experience.
“His statements are more political than medical and that’s a horrible disservice to the citizens of Florida.
He’s somebody whose job is to protect public …

Faithful Dynamic Timing Analysis of Digital Circuits Using Continuous Thresholded Mode-Switched ODEs
Thresholded hybrid systems are restricted dynamical systems, where the current mode, and hence the ODE system describing its behavior, is solely determined by externally supplied digital input signals and where the only output signals are digital ones generated by comparing an internal state variable to a threshold value. An attractive feature of such systems is easy composition, which is facilitated by their purely digital interface. A particularly promising application domain of thresholded h…

A Logic of Sattestation
We introduce a logic for reasoning about contextual trust for web addresses, provide a Kripke semantics for it, and prove its soundness under reasonable assumptions about principals' policies. Self-Authenticating Traditional Addresses (SATAs) are valid DNS addresses or URLs that are generally meaningful -- to both humans and web infrastructure -- and contain a commitment to a public key in the address itself. Trust in web addresses is currently established via domain name registration, TLS ce…

Feasibility and Performance of the Staged Z-Pinch: A One-dimensional Study with FLASH and MACH2
Z-pinch platforms constitute a promising pathway to fusion energy research. Here, we present a one-dimensional numerical study of the staged Z-pinch (SZP) concept using the FLASH and MACH2 codes. We discuss the verification of the codes using two analytical benchmarks that include Z-pinch-relevant physics, building confidence on the codes' ability to model such experiments. Then, FLASH is used to simulate two different SZP configurations: a xenon gas-puff liner (SZP1*) and a silver solid liner …

Measurement of Proton-Induced Reactions on Lanthanum from 55--200 MeV by Stacked-Foil Activation
Cerium-134 is an isotope desired for applications as a chemical analogue to the promising therapeutic radionuclide $^{225}$Ac, for use in bio-distribution assays as an in vivo generator of the short-lived positron-emitting isotope $^{134}$La. In the 50-100 MeV energy range relevant to the production of $^{134}$Ce by means of high-energy proton bombardment of lanthanum, existing cross section data are discrepant and have gaps at important energies. To address these deficiencies, a series of 17 $…

Imprints of Supermassive Black Hole Evolution on the Spectral and Spatial Anisotropy of Nano-Hertz Stochastic Gravitational-Wave Background
The formation and evolution of supermassive black holes (SMBHs) remains an open question in the field of modern cosmology. The detection of nanohertz (n-Hz) gravitational waves via pulsar timing arrays (PTAs) in the form of individual events and the stochastic gravitational wave background (SGWB) offers a promising avenue for studying SMBH formation across cosmic time, with SGWB signal being the immediately detectable signal with the currently accessible telescope sensitivities. By connecting t…
