Precision surveying using very long baseline interferometry [PDF]

Radio interferometry measurements were used to measure the vector baselines between large microwave radio antennas. A 1.24 km baseline in Massachusetts between the 36 meter Haystack Observatory antenna and the 18 meter Westford antenna of Lincoln ...

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

Multiwavelength Observations of Relativistic Jets from General Relativistic Magnetohydrodynamic Simulations

Galaxies, 2018
This work summarizes a program intended to unify three burgeoning branches of the high-energy astrophysics of relativistic jets: general relativistic magnetohydrodynamic (GRMHD) simulations of ever-increasing dynamical range, the microphysical theory of ...

Beyond Extracellular Vesicle (EV) Hype: Practical Solutions and Remaining Hurdles in EV Research, Manufacturing, and Clinical Translation

Advanced Science, Volume 13, Issue 26, 8 May 2026.
ABSTRACT Extracellular vesicles (EVs) are nanoscale mediators of intercellular communication with diverse molecular cargoes that reflect their cell of origin. Advances in isolation, detection, and single‐particle analytics have revealed increasing molecular and functional heterogeneity, while exposing limitations in how EV identity and activity are ...

Repurpose an FDA‐Approved Antibody Using DARPin‐Scaffolded Bridge Protein

Chemistry–Methods, Volume 6, Issue 5, May 2026.
The cell line and scalable upstream/downstream process development needed for every new monoclonal antibody are both highly expensive and time‐consuming, significantly increasing the cost of new antibody therapeutics. By contrast, the production of many synthetic binders can be accomplished rapidly and with lower production costs.

The whole-earth array ‒ Developments in very-long-baseline interferometry [PDF]

, 1971
Radio astronomers, in common with many others who work with radio antennas, have always felt rather handicapped by the basic physical relationship between the size of an antenna (measured in wavelengths) and its resolving power (or beamwidth): ΔΘ ~ λ/D ...

VLBI observations of the most radio-loud, narrow-line quasar SDSS J094857.3+002225 [PDF]

, 2006
We observed the narrow-line quasar SDSS J094857.3+002225, which has the highest known radio loudness for a narrow-line Seyfert~1 galaxy (NLS1), at 1.7--15.4 GHz with the Very Long Baseline Array (VLBA). This is the first very-long-baseline interferometry

A Novel Mechanism of Salvianolic Acid B in Postmyocardial Infarction Cardiac Protection: PHB1‐Driven Raf‐ERK Pathway Activation Promotes Cardiomyocyte Mitosis

MedComm, Volume 7, Issue 5, May 2026.
SalB binds to the C‐terminal of PHB1/2 heterodimer, inducing a conformational change that enhances Raf‐ERK pathway activation via Akt‐mediated phosphorylation, thereby promoting cardiomyocyte mitosis. ABSTRACT Heart failure (HF) following myocardial infarction remains a leading cause of global morbidity and mortality, necessitating novel therapeutic ...

Observation and Coordination Needs for Current, Near‐Future, and Next Generation Earth‐Observing SAR Systems

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract This paper summarizes an evaluation by experts of how coordination of Earth‐observing Synthetic Aperture Radar (SAR) missions among the world's space agencies could advance toward game‐changing scientific discoveries and fully realizing SAR's practical capability to address many issues facing society.
