Twins Among the Low Mass Spectroscopic Binaries
, 2008 We report an analysis of twins of spectral types F or later in the 9th Catalog of Spectroscopic Binaries (SB9). Twins, the components of binaries with mass ratio within 2% of 1.0, are found among the binaries with primaries of F and G spectral type. They

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Returns to Education: Evidence from UK Twins [PDF]
We use a new sample of UK female identical twins to estimate private economic returns to education. We report findings in three areas. First, we use identical twins, to control for family effects and genetic ability bias, and the education reported by ...

A case of intraplacental twin transfusion [PDF]
, 1967 There have been several reports of polycythaemia in one of uniovular twins with anaemia in the other twin. This syndrome has been recently fully recorded and reviewed by Corney and Aherne (1965).

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Marital Status and Unobserved Heterogeneity - Do twins suggest a genetic inheritance? [PDF]
The purpose of this study is to reveal the importance of unobserved heterogeneity on marital status. The results for monozygotic (identical) and dizygotic twins indicate an important genetic component in marital status.

Acta geneticae medicae et gemellologiae, 1974 Six new cases of monoamniotic twins are reported. All had true knots of the cord, the result being double survival in 5 cases and 11 normal children. The mechanism of twin development is described and monoamniotic twins are placed in accordance with the two theories from the literature.

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
