FGF21-dependent and -independent liver transcriptomic adaptations to low-protein feeding during aging
Abstract Aging is a risk factor for the development and progression of metabolic impairments. Dietary protein restriction (DPR) is protective against obesity- and age-related metabolic decline by the induction of the fibroblast growth factor (FGF21), which regulates body weight, lipid handling, and energy expenditure.

Moiré artifact reduction in grating interferometry using multiple harmonics and total variation regularization
Abstract X-ray interferometry is an emerging imaging modality with a wide variety of potential clinical applications, including lung imaging. A grating interferometer uses a diffraction grating to produce a periodic interference pattern and measures how a patient or sample perturbs the pattern, producing three unique images that highlight X-ray absorption, refraction, and small angle scattering, known as the attenuation, differential-phase, and dark-field images, respectively.
Obesogenic effects of warm temperature involve feeding adaptation by preoptic area leptin receptor neurons - Communications Biology
Abstract The preoptic area (POA) is a well-established regulator of body temperature, but its role in feeding behavior remains underexplored. Our study identifies leptin receptor (Lepr)-expressing neurons in the POA (POALepr) as critical component to suppress food intake (FI) and increase satiety in response to warm ambient temperatures.

Increase In Class Actions Alleging Violations Of Massachusetts Lie Detector Statute
A federal court decision in Massachusetts denying a motion to dismiss a putative class action has spurred a potential wave of similar claims, all arising under the Massachusetts Lie Detector Statute. The statute requires employers to notify job applicants in writing that it is illegal to administer a lie detector test as a condition of employment. A Massachusetts statute, ch.

Gun-free zones and active shootings in the United States: a matched case-control study
Research in context Prior to undertaking this study, we conducted an extensive literature review on the topic of gun-free zones and their relationship to active or mass shootings. We utilized two primary databases: PubMed and Scopus. The search was comprehensive, covering publications from their inception until the end date of our search in May 2022. We included studies without restriction to publication language.
Persistent Behavioral and Physiological Effects of Dietary Protein Restriction
Abstract Protein provides essential amino acids critical for survival. Recent research has identified that dietary protein restriction induces physiological and behavioral adaptations and that those adaptations are mediated by liver-produced fibroblast growth factor 21 (FGF21) that acts in the brain.
Individuals' travel to alcohol outlets: The fallacy of the local bar
Introduction Studies relating alcohol outlet density around homes to alcohol consumption produce mixed results. One possible explanation is that people travel to outlets away from their homes. This study aims to characterise individuals' trips to outlets, describe these trip locations relative to other activities and estimate associations between alcohol outlet density and trips to outlets.
'No place safe' as Israeli airstrikes bombard Gaza Strip: Live updates
Israeli airstrikes bombarded the Gaza Strip on Friday as the areas where Palestinian civilians could escape the expanding military operations continued to shrink and a United Nations official warned there's "no place safe for civilians in southern Gaza." The Palestinian Red Crescent Society, an independent humanitarian aid group, said an airstrike smashed into a house near its headquarters in Khan Younis on Friday, sending "dozens" of injured people to a nearby hospital and inciting panic...
Impact and Equity of New York City's Tobacco Retail Reduction Initiative
High levels of tobacco retailer density in communities is associated with a range of tobacco use behaviors and is a key structural driver of tobacco-related disparities. This study evaluates the impacts of New York City's (NYC) novel policy intervention to cap tobacco retail licenses on tobacco retailer density levels and neighborhood inequities in tobacco access.
Conference key agreement in a quantum network - npj Quantum Information
Abstract Quantum conference key agreement (QCKA) allows multiple users to establish a secure key from a shared multi-partite entangled state. In a quantum network, this protocol can be efficiently implemented using a single copy of a N-qubit Greenberger-Horne-Zeilinger (GHZ) state to distil a secure N-user conference key bit, whereas up to N-1 entanglement pairs are consumed in the traditional pair-wise protocol.
Single-emitter quantum key distribution over 175 km of fibre with optimised finite key rates - Nature Communications
Abstract Quantum key distribution with solid-state single-photon emitters is gaining traction due to their rapidly improving performance and compatibility with future quantum networks. Here we emulate a quantum key distribution scheme with quantum-dot-generated single photons frequency-converted to 1550 nm, achieving count rates of 1.6 MHz with {g}^{\left(2\right)}\left(0\right)=3.6\% and asymptotic positive key rates over 175 km of telecom fibre.
FGF21 is required for protein restriction to extend lifespan and improve metabolic health in male mice - Nature Communications
Abstract Dietary protein restriction is increasingly recognized as a unique approach to improve metabolic health, and there is increasing interest in the mechanisms underlying this beneficial effect. Recent work indicates that the hormone FGF21 mediates the metabolic effects of protein restriction in young mice.

Why Nuclear is an Emerging Technology for the Space Economy
By Dr. Christopher Morrison Nuclear energy has played a key supporting role in historic missions to Mars, Pluto, and across the Solar System for the last 50 years. On January 1 2019, the nuclear-powered New Horizons flew by the most distant object ever observed up close – Ultima Thule, after it having already flown by Pluto in 2015. Nuclear energy for space applications is nothing new.
