Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Mapping selective logging with Sentinel-1 image time series and a novel transformer-based model
International Journal of Applied Earth Observations and GeoinformationSelective logging (SL) is a major driver of forest degradation, yet its small and short-lived canopy openings remain difficult to detect in persistently cloudy tropical regions.

Earth Observation from Elliptical Orbits with Very Low Altitude Perigee [PDF]
, 2003 Small Earth Observation satellites can obtain higher resolution with smaller payloads when operating at very low altitude. The life limiting effect of residual atmospheric drag can be reduced flying elliptical, low-altitude perigee orbits, with perigee ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

A low-cost microsatellite platform for multispectral Earth observation
, 2007 In the Microsatellite Laboratory of the University of Bologna a project was started in 2003, aimed at the development of a multipurpose microsatellite platform named ALMASat. The launch onto orbit of the first prototype ALMASat-1 is currently foreseen by

Application Profile for Earth Observation Images [PDF]
, 2014 Based on the concept of an application profile as proposed by the Dublin Core initiative, the work presented in this manuscript attempts to propose an application profile for the Earth Observation images. This approach aims to provide an open and extensible model facilitating the sharing and management of distributed images within decentralized ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

FEBS Letters, EarlyView.Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...
