Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

Advanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

5‐Hydroxymethylcytosine Dynamics Reveals Coordinated Reprogramming of Parental Genomes and X Chromosome Dosage Balance in Mouse SCNT Embryos

Advanced Science, EarlyView.
Genome‐wide, high‐resolution profiling of hydroxymethylation in mouse SCNT embryos reveals a transient, allele‐symmetric 5hmC reprogramming pattern distinct from natural embryos, with X‐chromosomes and imprinting control regions resistant to proper remodeling.

Two Homogametic Genotypes – One Crayfish: On the Consequences of Intersexuality

iScience, 2020
Summary: In the Australian redclaw crayfish, Cherax quadricarinatus (WZ/ZZ system), intersexuals, although exhibiting both male and female gonopores, are functional males bearing a female genotype (WZ males).

A Cold Stress‐Activated Endocrine Sentinel Chemical Hormone Promotes Insect Survival via Mitochondrial Adaptations Through the Adipokinetic Hormone Receptor

Advanced Science, EarlyView.
Seasonal cold adaptation is vital for insect survival, yet the molecular mechanisms linking diapause to mitochondrial resilience remain largely unresolved. We identify ascaroside C9 (asc‐C9) as a key endocrine signal that enhances diapause survival during cold stress by activating the AKHR–PGC1α–UCP4 axis, thereby driving cold‐induced lipolysis and ...

Chronic ER Stress Triggers Cell‐Surface Chaperones as the Therapeutic Targets of CAR Cells in Acute Myeloid Leukemia

Advanced Science, EarlyView.
Acute myeloid leukemia (AML) remains a therapeutic challenge due to its heterogeneity and limited targets. Here, multi‐omics analyses are utilized, and it is revealed that AML cells, particularly the FLT3‐ITD+ subtype, undergo chaperone‐mediated ER stress, inducing surface translocation of ER chaperones.
