Gas stoves are filling millions of homes with hidden toxic air
Stanford researchers found that gas stoves expose Americans to surprisingly high levels of nitrogen dioxide—often matching or exceeding outdoor pollution. For millions, cooking alone pushes NO2 over long-term safety thresholds. Smaller homes, renters, and rural households face the highest concentrations. Cleaner cooking technologies could substantially reduce the risks.

‘We can have abundant rivers and wildlife’: Director of ‘The American Southwest’ on new film
At its roots, The American Southwest, from Fin and Fur Films, is a natural history documentary. “I’m a wildlife guy,” says director Ben Masters, who founded Fin and Fur in 2012. His infatuation with nature comes through in the film’s exploration of the southwestern United States, traced along the path of the Colorado River from […]

Holographic Gaseous Lenses for High-Power Lasers
The capabilities of the world's highest energy and peak-power pulsed lasers are limited by optical damage, and further advances in high-intensity laser science will require optics that are substantially more robust than existing components. We describe here the experimental demonstration of off-axis diffractive gaseous lenses capable of withstanding extreme laser fluence and immune to cumulative damage. We used less than 8 mJ of energy from interfering ultraviolet laser pulses to holographicall…

Modeling Emission-Line Surface Brightness in a Multiphase Galactic Wind: An O VI Case Study
We present a fast and robust analytic framework for predicting surface brightness (SB) of emission lines in galactic winds as a function of radius up to $\sim 100$ kpc out in the circum-galactic medium. We model multi-phase structure in galactic winds by capturing emission from both the volume-filling hot phase (T $\sim 10^{6-7}$ K) and turbulent radiative mixing layers that host intermediate temperature gas at the boundaries of cold clouds (T $\sim 10^4$ K). Our multi-phase framework makes sig…

Elastic Energy Storage Mechanism in Hovering Animal Flight: A Discriminative Method Based on Wing Kinematics
Existing research has yet to reach a consensus on whether and how small flying animals utilize elastic energy storage mechanisms to reduce flight energy expenditure, and there is a lack of systematic and universal methods for assessment. To address these gaps, this study proposes a method to evaluate elastic energy storage capacity based on wing kinematic parameters (flapping amplitude and flapping frequency), grounded in the hypothesis that animals tend to minimize flight energy expenditure. B…

Consistent control of drying rates of solution thin films on wafer-sized substrates by dynamic air-knife drying with optimal trajectories
This work tackles the problem of achieving consistent drying rates of a solution film deposited on a $20\,\rm{cm}$-wide substrate ($\approx $ silicon-wafer size) that is driven under a narrow air flow ejected by a slot nozzle (or "air knife"). The main prerequisite of the work is that the drying rate of the solution film is highly decisive for a certain performance indicator of the deposited film at a particular, critical concentration $c_{\rm crit.}$. Empirically, this concentration can be ass…

Cancer rates among those aged 15 to 49 have increased by 10 percent since 2000
even as they have fallen among older people.
Young women are more affected than men.
From ages 15 through 49, women have a cancer rate that is 83 percent higher than men in the same age range.

What researchers suspect may be fueling cancer among millennials
Studies suggest modern life may be fueling the rise of cancer in younger adults, with factors like ultra-processed foods and chemicals under scrutiny.

Three-fold Superstructured Superlattice HfN/HfAlN Thin Films for Enhanced Toughness
To simultaneously achieve high hardness and high toughness in protective coatings remains a fundamental challenge. Here, we harness the superlattice architecture to combine Koehler hardening while the coherent interfaces reduce the crack driving force and improve toughness, enabling coatings that are both hard and damage tolerant. We design and fabricate epitaxial HfN$_{1.33}$/Hf$_{0.76}$Al$_{0.24}$N$_{1.15}$ superlattices, deposited on MgO(001) substrates using low-energy, high-flux ion-assist…
