Peter Pan Discs: finding Neverland’s parameters
"Peter Pan discs are a recently discovered class of long-lived discs around low-mass stars that survive for an order of magnitude longer than typical discs. In this paper we use disc evolutionary models to determine the required balance between initial conditions and the magnitude of dispersal processes for Peter Pan discs to be primordial." Read More

Genomic basis of European ash tree resistance to ash dieback fungus
"Scientists say there is new hope in the fight against a disease that is devastating ash trees. A study has identified the genes that give trees resistance to ash dieback, which arrived in the UK in 2012 and has now spread to almost every part of the country. The discovery suggests that trees could now be bred that are unaffected by the epidemic. The research is published in the journal Nature Ecology and Evolution." Read More on BBC News

Cardiovascular Predictive Value and Genetic Basis of Ventricular Repolarization Dynamics"Early prediction of cardiovascular risk in the general population remains an important issue. The T-wave morphology restitution (TMR), an ECG marker quantifying ventricular repolarization dynamics, is strongly associated with cardiovascular mortality in patients with heart failure. Our aim was to evaluate the cardiovascular prognostic value of TMR in a UK middle-aged population and identify any genetic contribution." Read More

Understanding Aggregation Induced Emission in a Propeller‐Shaped Blue Emitter.
"Organic fluorophores with an enhanced emission in the condensed phase have great potential for the design of optoelectronic materials. Several propeller‐shaped molecules show aggregation‐induced emission (AIE), in particular, silole derivatives have attracted wide attention because of their significant quantum yields in the solid state."

The full dynamics of energy relaxation in large organic molecules: from photo-excitation to solvent heating."In some molecular systems, such as nucleobases, polyenes or the active ingredients of sunscreens, substantial amounts of photo-excitation energy are dissipated on a sub-picosecond time scale, raising questions such as: where does this energy go or among which degrees of freedom it is being distributed at such early times? Here we use transient absorption spectroscopy to track excitation energy dispersing from the optically accessible vibronic subsystem into the remaining vibrational subsystem of the solute and solvent. Monitoring the flow of energy during vibrational redistribution enables quantification of local molecular heating". Read more

Tax evasion as contingent debt.
"This paper studies income-tax evasion in a quantitative incomplete-markets setting with heterogeneous agents. A central aspect is that, realistically, evaded taxes are a form of contingent debt. Since evasion becomes part of a portfolio decision, risk and credit considerations play a central part in shaping it. The model calibrated to match estimated average levels of evasion does a good job in producing observed cross-sectional average evasion rates that decline with age and with earnings.” Read more
