The Structure and Kinematics of Three Class 0 Protostellar Jets from JWST

The Astrophysical Journal
We present observations of jets within 2000 au of three deeply embedded protostars using 2.9–27 μ m observations with JWST. These observations show the morphologies and kinematics of the collimated jets from three protostars, the low-mass Class 0 ...

Blood‐based proteomic profiling reveals context‐dependent changes in BCL2‐associated signaling during taxane therapy in breast cancer patients

FEBS Open Bio, EarlyView.
Chemotherapy side effects significantly impact cancer survivors' quality of life. Using protein levels in blood samples from breast cancer patients before and after 12 weeks of taxane treatment, we detected treatment‐dependent changes in calcium signaling and aging pathways associated with cancer recurrence.

Multiple Components of the Outflow in the Protostellar System HH 212: Outer Outflow Shell, Rotating Wind, Shocked Wind, and Jet

The Astrophysical Journal
We present the Atacama Large Millimeter/submillimeter Array Band 7 observations of the CO ( J = 3−2) line emission of the protostellar system HH 212 at ∼24 au spatial resolution and compare them to those of the SiO ( J = 8−7) and SO ( J = 8−7) line ...

Outflows and Accretion in Young Stellar Objects [PDF]

Symposium - International Astronomical Union, 2004
Outflows in young stellar objects are powered by accretion, and ∼ 0.1 of the accreted material is lost in the outflow. Observational evidence is analyzed in the context of models for the origin of the wind. Winds in FU Ori objects are clear examples of disk winds.

SPARCO : a semi-parametric approach for image reconstruction of chromatic objects. Application to young stellar objects

, 2014
11 pages, 11 figures, accepted in A&AInternational audienceContext. The emergence of optical interferometers with three and more telescopes allows image reconstruction of astronomical objects at the milliarcsecond scale.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Multiple Shells Driven by Disk Winds: ALMA Observations in the HH 30 Outflow

The Astrophysical Journal
We present archival Atacama Large Millimeter/submillimeter Array band 6 observations of the ^13 CO ( J = 2–1) and ^12 CO ( J = 2–1) molecular line emission of the protostellar system associated with HH 30.

A Search for and Characterization of Young Stellar Objects in N206, An H II Complex in the Large Magellanic Cloud

, 2011
I have identified 51 young stellar object candidates in N206, an H II complex in the nearby Large Magellanic Cloud galaxy. Using archival images from the Spitzer Space Telescope, supplemented with other infrared and optical images, I located point ...

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

FEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

LAMOST Reveals Long-lived Protoplanetary Disks

The Astronomical Journal
While both observations and theories demonstrate that protoplanetary disks are not expected to live much longer than ∼10 Myr, several examples of prolonged disks have been observed in the past.
