Background: There are no independent studies measuring the availability of premium brand counterfeit cigarettes in New York City from licensed retailers.
Methods: We forensically analyzed the cigarette packaging of Marlboro Gold (n = 1021) purchased from licensed tobacco retailers in New York City, using ultraviolet irradiation and light microscopy to determine whether they were counterfeit.
Results: We find that while only 0.5% (n = 5) of our sample exhibits at least one characteristic synonymous with counterfeit packaging, none of our packs can be conclusively classified as counterfeit.
Conclusions: We do not find any counterfeit Marlboro Gold packs purchased at full price from licensed cigarette retailers throughout New York City. Future research using test purchases should include other venues (eg, street and online) and specifically ask for discounts to ascertain the overall presence of counterfeit cigarettes.
Implications: This is the first study to independently measure the availability of counterfeit cigarette packs purchased at full price from licensed retailers in New York City. We find that none of the Marlboro Gold packs purchased from licensed cigarette retailers are counterfeit.

Hydrogen internal combustion engines offer a near-term decarbonisation pathway for hard to electrify sectors such as non-road mobile machinery (NRMM). However, few hydrogen-specific engines have ever been developed with the twin-goals of maximising low carbon energy efficiency and delivering air quality co-benefits. We present analyses of dynamometer-derived nitrogen oxides (NO) tailpipe emissions from four variants of a ∼55 kW four-cylinder port fuelled injection spark ignition hydrogen internal combustion engine (H2ICE) suitable for a range of uses within the NRMM industry.

In this report, we describe the photoluminescence of a homoleptic uranium(IV) alkoxide complex. Excitation of [Li(THF)][U(O Bu)] leads to the first example of photoluminescence from a well-defined actinide complex originating from an f-f excitation, supported by second order multiconfigurational electronic structure calculations including spin-orbit coupling. These calculations show strong spin-orbit coupling between the excited triplet and singlet states for the 5f-orbital manifold, which leads to a long-lived excited state lifetime of 0.

Despite the wealth of single-cell multi-omics data, it remains challenging to predict the consequences of novel genetic and chemical perturbations in the human body. It requires knowledge of molecular interactions at all biological levels, encompassing disease models and humans. Current machine learning methods primarily establish statistical correlations between genotypes and phenotypes but struggle to identify physiologically significant causal factors, limiting their predictive power.

Hydrogen (H), as a high-energy-density molecule, offers a clean solution to carry energy. However, the high diffusivity and low volumetric density of H pose a challenge for long-term storage and transportation. Liquid organic hydrogen carriers (LOHCs) have been suggested as a strategic way to store and transport hydrogen in stable molecules.

Cardiovascular disease is a leading cause of death worldwide. The differentiation of human pluripotent stem cells (hPSCs) into functional cardiomyocytes offers significant potential for disease modeling and cell-based cardiac therapies. However, hPSC-derived cardiomyocytes (hPSC-CMs) remain largely immature, limiting their experimental and clinical applications.
