SPITZER OBSERVATIONS CONFIRM AND RESCUE THE HABITABLE-ZONE SUPER-EARTH K2-18b FOR FUTURE CHARACTERIZATION [PDF]

, 2017
The recent detections of two transit events attributed to the super-Earth candidate K2-18b have provided the unprecedented prospect of spectroscopically studying a habitable-zone planet outside the solar system. Orbiting a nearby M2.5 dwarf and receiving

Genome‐Wide and Multi‐Omics Analysis Identified DNA‐Interacting Circular RNA circFOXK2 as MLL1 Regulator for Histone H3K4 Methylation in Pancreatic Ductal Adenocarcinoma

Advanced Science, EarlyView.
Circular RNA circFOXK2 is frequently upregulated in pancreatic ductal adenocarcinoma to promote tumor heterogeneity, growth, and metastasis. Through circRNA‐DNA interaction at different genomic locations, circFOXK2 removes the PPIE inhibitory effects on MLL1 for gene‐activating H3K4 methylation of the oncogenes.

Glyphosate internal dose estimation: comparing passive dosimetry and biomonitoring in simulated heavy residential herbicide application

Arhiv za Higijenu Rada i Toksikologiju
Glyphosate exposure is commonly assessed using either passive dosimetry or biomonitoring. This study tests the hypothesis that internal dose estimates derived from passive dosimetry are higher and more uncertain than those derived from biomonitoring by ...

Enhancing Near‐Room‐Temperature Thermoelectric Performance of n‐Type Mg3(Sb, Bi)2‐Based Materials via ZrB2 Heterointerface Engineering

Advanced Science, EarlyView.
A conductive ZrB2 ceramic composite strategy was developed for Mg3(Sb, Bi)2 thermoelectrics to regulate carrier transport and phonon scattering through heterointerface engineering. The 1.0 wt.% ZrB2 composite achieved enhanced room‐temperature performance, with a power factor of 28.51 µW cm−1 K−2 and a peak ZT of 1.22 at 573 K.

High‐Power Hybrid Nanogenerator With Multi‐Degree‐of‐Freedom Mechanical Coupling for Harvesting Water Wave Energy

Advanced Science, EarlyView.
A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

Discrete 2D Material Programming for 3D Shaping and Morphogenesis‐Inspired 4D Bioprinting

Advanced Science, EarlyView.
Cell‐compatible discrete 2D material programming enables 2‐to‐3D shape transformation and morphogenesis‐inspired 4D bioprinting. By patterning cell‐supportive microdomains within a responsive hydrogel, the approach programs in‐plane growth to encode target metrics.

Switching Spike Plasticity Shapes ACE2 Engagement Across SARS‐CoV‐2 Variants

Advanced Science, EarlyView.
Conformational plasticity governs SARS‐CoV‐2 spike function and ACE2 recognition. Using high‐speed AFM and single‐molecule force spectroscopy, we analyzed the ancestral spike and nine variants, revealing progressive rigidification from Delta, variable plasticity in Omicron sublineages, and JN.1 compaction.

K2 DISCOVERS A BUSY BEE: AN UNUSUAL TRANSITING NEPTUNE FOUND IN THE BEEHIVE CLUSTER [PDF]

, 2016
Open clusters have been the focus of several exoplanet surveys, but only a few planets have so far been discovered. The Kepler spacecraft revealed an abundance of small planets around small cool stars, therefore, such cluster members are prime targets ...
