New Species of Babinskaiidae (Insecta: Neuroptera) From the Mid‐Cretaceous of Myanmar and the Morphological Divergence of the Family Across the Cretaceous

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Two new species of Babinskaiidae are reported from the mid‐Cretaceous of Myanmar and the morphological divergence of the family across the Cretaceous is quantified. The Babinskaiidae assemblages from the Lower Cretaceous Crato Formation and the Upper Cretaceous Kachin amber are separated by a pronounced morphological divergence in both overall size and

Dose‐Dependent Effects of Biochar on Soil Revealed by Fast Field‐Cycling (FFC) NMR: From Molecular Water Dynamics to Soil Functionality

Magnetic Resonance in Chemistry, Volume 64, Issue 3, Page 349-364, March 2026.
Dose–response of biochar in a clay soil: fifteen mixtures (fBC 0–1) reveal nonlinear thresholds (pH/EC) and sharp WHC gains near fBC ≈ 0.3–0.5. Coupled FT‐IR and FFC‐NMR (0.01–10 MHz; ModelFree τc distributions) link water dynamics to soil functionality.

Comparative Analysis of Physicochemical and Functional Properties in Commercial Protein Concentrates and Isolates From Pulses

Sustainable Food Proteins, Volume 4, Issue 1, March 2026.
This study evaluated the physicochemical and functional properties of commercially produced protein concentrates and isolates from pea, lentil, faba bean, and soybean, using air‐classification and wet fractionation. Protein concentrates showed significant differences in physicochemical and functional characteristics compared with isolates.

Millinovae: A New Class of Transient Supersoft X-Ray Sources without a Classical Nova Eruption

The Astrophysical Journal Letters
Some accreting binary systems containing a white dwarf (such as classical novae or persistent supersoft sources) are seen to emit low-energy X-rays with temperatures of  ∼ 10 ^6 K and luminosities exceeding 10 ^35 erg s ^−1 .

A 70 pc Diameter Nova Superremnant Surrounding the Recurrent Nova RS Ophiuchi

The Astronomical Journal
Recurrent novae undergo thermonuclear-powered eruptions separated by less than 100 yr, enabled by subgiant or red giant donors transferring hydrogen-rich matter at very high rates onto their massive white dwarf companions.

X-Ray Spectroscopy Mass Constraints on V1674 Her: The Fastest Nova does not have a Near-Chandrasekhar White Dwarf

The Astrophysical Journal
V1674 Her (Nova Her 2021) is the fastest classical nova ever recorded, with an optical decline time of t _2  ∼ 1 day, typically interpreted as evidence for a white dwarf mass close to the Chandrasekhar limit.

Observations of Southern Dwarf Novae [PDF]

International Astronomical Union Colloquium, 1979
Preliminary results of spectroscopic and photometric data for five dwarf novae are presented : 1) V 436 Cen. The orbital period of 0.0669 days was determined from radial velocity variations. The RV half amplitude of the primary, K1. = 159 km/s, implies very small masses of M1 ≲ 0.20 M⊙ and M2 = 0.18 M⊙ for the binary components.2) Z Cha. Broad emission
