Graphene-Oxide-Reinforced Perfluorocyclobutyl Polymer Coatings for Tunable Tortuosity-Driven Corrosion Protection
Polymeric coatings are widely used to mitigate corrosion by limiting the transport of water, oxygen, and aggressive ions, yet their long-term performance is often constrained by permeability, electrostatic heterogeneity, and mechanically induced defects. Perfluorocyclobutyl (PFCB) polymers offer intrinsically low permeability and high chemical stability, but opportunities remain to further engineer ion-transport pathways without sacrificing adhesion or durability.

Philippine Economy Macroeconomic Perspectives 2026: Inputs to the Analysis of the President’s Budget for FY 2027
BB2026-01 2026 This Budget Brief assesses the Philippine economy’s macroeconomic performance and outlook for 2026 as an input to the analysis of the proposed FY 2027 National Budget. It highlights the sharp slowdown in economic growth, persistent weakness in household consumption and investment, and renewed inflationary pressures driven by food, energy, transport, and external supply shocks.
Seeds of a Food Crisis: Fertilizer Supply Disruptions in the Philippines Amid the US–Iran Conflict
The ongoing geopolitical conflict in the Middle East has exposed the fragility of global fertilizer supply chains, with direct consequences for Philippine food security. World urea prices nearly doubled between February and April 2026, a critical shock for the Philippines, which imports about 90% of its fertilizer requirement and where rice remains central to both consumption and production.

The Missing Link: Capturing the Realization of Investments Commitments
This discussion paper aims to answer a perennial question, “are investment pledges being realized?” The findings of the study are indicative of investment realization.
Rising Borders, Increasing Barriers: The Potential Impact of US Tariff Pronouncements on the Philippines
This paper examines the potential impact of US tariff pronouncements on the Philippines under a second Trump administration, revealing both sectoral challenges and opportunities. The partial equilibrium analysis using the World Bank’s World Integrated Trade Solution Software for Market Analysis and Restrictions on Trade (WITS-SMART) reveals significant trade erosion for more complex, high-value sectors, while smaller gains are concentrated in less complex products.
Scaling Up the Middle-Income Ladder: Determinants of Attaining a Higher Income Status (Towards Ramping Up and Sustaining a Philippine Priority Reform Agenda)
The Philippines has languished in the lower middle-income country (LMIC) classification for nearly four (4) decades, closely approaching the threshold set for upper middle-income countries (UMICs) in 2019 before the COVID-19 pandemic disrupted this transition. Under the Philippine Development Plan (PDP) 2023-2028, the Philippines is targeting to finally attain UMIC status by 2025.
Temperate functional niche availability not resident-invader competition shapes tropicalisation in reef fishes
Nature Communications, Apr 2023 This is a preview of a remote PDF: https://www.nature.com/articles/s41467-023-37550-5.pdf Miller, Mark G. R., Reimer, James D., Sommer, Brigitte, Cook, Katie M., Pandolfi, John M., Obuchi, Masami, Beger, Maria. , Nature Communications, DOI: 10.1038/s41467-023-37550-5
Behind the cover: December 2022
Each month, Physics Today editors explore the research and design choices that inspired the latest cover of the magazine. According to the Health Resources and Services Administration, 17 people die each day waiting for an organ transplant in the US. Bioprinting, illustrated on the December issue’s cover, is a promising technology for fabricating the needed tissues and organs.
Behind the Cover: September 2021
Each month, Physics Today editors explore the research and design choices that inspired the latest cover of the magazine. The cover: The longest bone in the human body, the femur connects to the pelvis in a classic ball-and-socket joint, which defines the hip. The high-resolution computed tomography (CT) scan of the bone on this month’s cover, which shows a thin coronal (or frontal) cross section created from a three-dimensional data set, reveals the bone’s microstructure.
Replacement Roadie 20 and Tundra T-Rex Lid Latches

Recognize these latches from anywhere? If you own an ATV, you might. These latches are built to withstand the pounding an ATV dishes out, and they’ll also last for years on your YETI® cooler. Same goes for the latch keepers, which are molded directly into the cooler’s body.
Classical turbulence observed in a superfluid
Stirred coffee, like any normal fluid, can swirl around with an arbitrary speed and angular momentum. That’s not the case for superfluids. They can rotate only by winding themselves around vortices whose circulation is quantized. Their flow is also completely inviscid. That relative simplicity has turned superfluids such as helium and Bose–Einstein condensates into model systems for studying turbulence (see the article by Joe Vinen and Russell Donnelly, Physics Today, April 2007, page 43).
The upper atmosphere’s natural thermostat
Occasionally, our sun belches massive plumes of plasma from its corona that stream Earthward. When a fast coronal mass ejection (CME) arrives, it compresses Earth’s magnetosphere and can reconfigure the planet’s magnetic field lines. The reconfiguration enhances electric currents and energizes charged particles. Those currents and particles heat the tenuous atmosphere—hundreds of kilometers in altitude—which then expands outward. Low-orbiting satellites should thus experience more drag.
Oganesson is an oddball among noble gases
Since the discovery of nuclear fission in 1938, scientists have artificially produced 26 elements and hundreds of isotopes, all by using nuclear reactions (see the article by Yuri Oganessian and Krzysztof Rykaczewski, Physics Today, August 2015, page 32). For the newly created elements, their lifetimes are often so short—and their yields so low—that their chemical and physical properties cannot be analyzed experimentally. Researchers must instead turn to atomic calculations.
Electronics robust enough for Venus
Day or night, the mean temperature on Venus is about 460 °C, an extreme demonstration of the heat-trapping efficiency of the carbon dioxide that makes up most of the planet’s thick atmosphere. At the crushing surface pressure of 9.4 MPa—93 times that on Earth—the gas exists in a supercritical liquid-like state. Overhead, sulfuric acid clouds tens of kilometers thick are blown around the planet in hurricane-force winds.
