The impact of HPAI trade restrictions on U.S. poultry exports in 2022–23

Applied Economic Perspectives and Policy, EarlyView.
Abstract In early 2022, APHIS confirmed a case of highly pathogenic avian influenza (HPAI), signaling the beginning of an extensive HPAI outbreak. Since the start of the outbreak in 2022, more than 105 million birds across commercial and backyard operations in 48 states have been affected. Many countries, including top importers of U.S.

Early Accretion of Large Amounts of Solids for Directly Imaged Exoplanets

The Astrophysical Journal
As the number of planetary-mass objects (PMOs; ⪅13 M _Jupiter ) at wider separation (⪆10 au) grows, there is emerging evidence that they form differently from their higher-mass brown dwarf counterparts.

The Environmental Emission and Climate Change Impact of Hydrogen Fuel Derived from Photocatalysis Water‐Splitting Reaction

Advanced Energy and Sustainability Research, EarlyView.
In this works, life cycle analysis (LCA) of photocatalysis hydrogen synthesis reaction based on a pilot scale system is presented. Through the LCA, it is shown that majority of the carbon emission of the process is contributed by photocatalyst synthesis process and the use of sacrificial reagent in the photocatalytic hydrogen evolution reaction ...

An Absolute Mass, Precise Age, and Hints of Planetary Winds for WASP-121A and b from a JWST NIRSpec Phase Curve

The Astronomical Journal
We have conducted a planetary radial velocity measurement of the ultrahot Jupiter WASP-121b using JWST NIRSpec phase curve data. Our analysis reveals the Doppler shift of the planetary spectral lines across the full orbit, which shifts considerably ...
