Convergence Deficits in Myoclonus‐Dystonia Point to Cerebellar Impairment

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.

Ceropegia andhrica (Apocynaceae), a new species from Andhra Pradesh, India

Nordic Journal of Botany, EarlyView.
A new hysteranthous species of Ceropegia, C. andhrica P.Chiranjeevi, K.Prasad & V.Nagaraju sp. nov. (Apocynaceae), is described from the Paderu forest division, Alluri Sitharamaraju District, Andhra Pradesh, India. It morphologically resembles Ceropegia vemanae and C.

HCN and C2H2 in the Atmosphere of a T8.5+T9 Brown Dwarf Binary

The Astrophysical Journal Letters
T-type brown dwarfs present an opportunity to explore atmospheres teeming with molecules such as H _2 O, CH _4 , and NH _3 , which exhibit a wealth of absorption features in the mid-infrared.

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

A Possible Correlation between Metallicity and Near-IR Color for Late-M and L Dwarfs

The Astrophysical Journal
We examine the relationship between metallicity and J − K color for 64 benchmark late-M and L dwarfs, all of which are wide companions to higher-mass stars, and six of which are new discoveries.

Where lies the peak of the brown dwarf binary separation distribution ?

, 2008
Searches for companions of brown dwarfs by direct imaging probe mainly orbital separations > 3-10 AU. On the other hand, previous radial velocity surveys of brown dwarfs are mainly sensitive to separations smaller than 0.6 AU.

Some love them, others hate them: Understanding farmers' tree planting decisions in Scotland

People and Nature, EarlyView.
Abstract Agroforestry is increasingly recognized as a sustainable agricultural land use system with potential to sequester carbon, create and repair habitats, enhance biodiversity and offer environmental and socio‐economic benefits, including improved agricultural productivity.

The Expanding Role of Gene Sequencing in Shaping Fetal Therapies: Clinical and Ethical Considerations

Prenatal Diagnosis, EarlyView.
ABSTRACT In utero interventions are transformative in addressing genetic and anatomic conditions during fetal development. Next generation sequencing enables early genetic testing, playing a pivotal role in prenatal decision‐making by supporting risk stratification, precise and timely diagnosis, which directly informs eligibility for fetal surgical and

Medium-resolution 0.97–5.3 μm Spectra of Very Young Benchmark Brown Dwarfs with NIRSpec on Board the James Webb Space Telescope

The Astronomical Journal
Spectra of young benchmark brown dwarfs with well-known ages are vital to characterize other brown dwarfs, for which ages are in general not known. These spectra are also crucial to test atmospheric models, which have the potential to provide detailed ...
