Deep Gulf of Mexico seeps are not a significant source of methane to the atmosphere
Hydrocarbon seeps release fossil methane into the marine environment, but emission of this seep-derived methane to the atmosphere is challenging to constrain. Here, we measure the concentration and radiocarbon content of dissolved methane in seawater above seeps in the northern Gulf of Mexico that h...

High Spectral Energy Density All-Fiber Nanosecond Pulsed 1.7 μm Light Source for Photoacoustic Microscopy
We present a high spectral energy density all-fiber nanosecond pulsed 1.7 μm light source specifically designed for photoacoustic microscopy (PAM). The system targets the 1st overtone absorption of C–H bonds near 1720 nm within the near-infrared-III (NIR-III) window, where lipids exhibit strong opti...

New insights into the olfactory development disrupted by 4-tert-Octylphenol in offspring mice
4-tert-Octylphenol (4t-OP) is an endocrine-disrupting chemical widely used in industrial products that exert neurotoxic effects, thus affecting hippocampal neurogenesis and cognitive function. However, its effect on the subventricular zone (SVZ), a crucial neurogenic niche, remains unclear. The pres...

Longitudinal antibody titers measured after COVID-19 mRNA vaccination can identify individuals at risk for subsequent infection
Although COVID-19 posed a major threat, the success of mRNA vaccines enabled rapid development and distribution, helping to control the pandemic. However, vaccine-induced immunity wanes over time, and large individual differences make it difficult to design optimal booster strategies. Identifying po...
