Phytoplankton adaptation to marine ecosystems: insights into photophysiological functional diversity
, 2011 The aim of this study was to investigate the diversity of the photoprotective responses activated by phytoplankton at short temporal scales, i.e. the non-photochemical quenching of Chl a fluorescence (NPQ) associated with the xanthophyll cycle (XC ...

FEBS Open Bio, EarlyView.Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

PLoS ONEIntroductionGeneral anaesthesia is essential in surgical interventions because it reduces stress and restricts the animal's movement. However, it can interfere with the circadian clock and, consequently, with several physiological functions, including ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Single-cycle light : [Interview]
, 2010 Few-cycle light pulses are important for attosecond science and extremely nonlinear optics. Alfred Leitenstorfer from the University of Konstanz spoke to Nature Photonics about how erbium-doped fibre laser technology can generate single-cycle pulses at telecommunications wavelengths.

Effect of varying light-dark cycle on periodic axial variation.
, 2013 (A) Transgenic animals expressing Rho-eGFP were housed for 2 weeks in constant darkness, switched to 24 h (12D:12L) for 3 days (LD) and then in constant light for 2 weeks prior to imaging. The intensity profile of the cell is shown below.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains
FEBS Open Bio, EarlyView.The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Cycling, lighting, accidents and responsibility
, 2017 Local authority lighting engineers have a responsibility to optimise the energy used by road lighting, to meet budgets and to meet environmental targets. Reducing the provision of road lighting can, however, lead to public criticism - articles in the Lighting Journal have shown part-night switch-off blamed for a fall, death from a road accident and for

Starting from ~50-cycle-long pulses at 1035 nm, we show how gas-filled hollow-core fibers facilitate the generation of intense few-cycle light transients from the terahertz to the visible ...

Optimization of the LWR Nuclear Fuel Cycle for Minimum Waste Production
, 2003 The once through nuclear fuel cycle adopted by the majority of countries with operating commercial power reactors imposes a number of concerns. The radioactive waste created in the once through nuclear fuel cycle has to be isolated from the environment
