TL;DR: In this article, the authors present the first systematic study of the costs of cyber-crime in the UK and the world as a whole, focusing on the direct costs, indirect costs and defence costs.
Abstract: This chapter documents what we believe to be the first systematic study of the costs of cybercrime. The initial workshop paper was prepared in response to a request from the UK Ministry of Defence following scepticism that previous studies had hyped the problem. For each of the main categories of cybercrime we set out what is and is not known of the direct costs, indirect costs and defence costs – both to the UK and to the world as a whole. We distinguish carefully between traditional crimes that are now “cyber” because they are conducted online (such as tax and welfare fraud); transitional crimes whose modus operandi has changed substantially as a result of the move online (such as credit card fraud); new crimes that owe their existence to the Internet; and what we might call platform crimes such as the provision of botnets which facilitate other crimes rather than being used to extract money from victims directly. As far as direct costs are concerned, we find that traditional offences such as tax and welfare fraud cost the typical citizen in the low hundreds of pounds/euros/dollars a year; transitional frauds cost a few pounds/euros/dollars; while the new computer crimes cost in the tens of pence/cents. However, the indirect costs and defence costs are much higher for transitional and new crimes. For the former they may be roughly comparable to what the criminals earn, while for the latter they may be an order of magnitude more. As a striking example, the botnet behind a third of the spam sent in 2010 earned its owners around $2.7 million, while worldwide expenditures on spam prevention probably exceeded a billion dollars. We are extremely inefficient at fighting cybercrime; or to put it another way, cyber-crooks are like terrorists or metal thieves in that their activities impose disproportionate costs on society. Some of the reasons for this are well-known: cybercrimes are global and have strong externalities, while traditional crimes such as burglary and car theft are local, and the associated equilibria have emerged after many years of optimisation. As for the more direct question of what should be done, our figures suggest that we should spend less in anticipation of cybercrime (on antivirus, firewalls, etc.) and more in response – that is, on the prosaic business of hunting down cyber-criminals and throwing them in jail.

TL;DR: The crystal structure of DegP, a widely conserved heat shock protein that combines refolding and proteolytic activities, is solved and the chaperone conformation is solved, in which substrate binding in addition to catalysis is abolished.
Abstract: Molecular chaperones and proteases monitor the folded state of
other proteins. In addition to recognizing non-native conformations,
these quality control factors distinguish substrates that
can be refolded from those that need to be degraded1. To
investigate the molecular basis of this process, we have solved
the crystal structure of DegP (also known as HtrA), a widely
conserved heat shock protein that combines refolding and
proteolytic activities2. The DegP hexamer is formed by staggered
association of trimeric rings. The proteolytic sites are located in a
central cavity that is only accessible laterally. The mobile sidewalls
are constructed by twelve PDZ domains, which mediate the
opening and closing of the particle and probably the initial
binding of substrate. The inner cavity is lined by several hydrophobic
patches that may act as docking sites for unfolded
polypeptides. In the chaperone conformation, the protease
domain of DegP exists in an inactive state, in which substrate
binding in addition to catalysis is abolished.

TL;DR: The cingulum bundle is a prominent white matter tract that interconnects frontal, parietal, and medial temporal sites, while also linking subcortical nuclei to the cingulate gyrus, and non‐invasive imaging implicates it in executive control, emotion, pain, and episodic memory.

TL;DR: It is found that the breadth of gene expression and the extent of purifying selection gradually decrease during development, whereas the amount of positive selection and expression of new genes increase during development.
Abstract: The evolution of gene expression in mammalian organ development remains largely uncharacterized. Here we report the transcriptomes of seven organs (cerebrum, cerebellum, heart, kidney, liver, ovary and testis) across developmental time points from early organogenesis to adulthood for human, rhesus macaque, mouse, rat, rabbit, opossum and chicken. Comparisons of gene expression patterns identified correspondences of developmental stages across species, and differences in the timing of key events during the development of the gonads. We found that the breadth of gene expression and the extent of purifying selection gradually decrease during development, whereas the amount of positive selection and expression of new genes increase. We identified differences in the temporal trajectories of expression of individual genes across species, with brain tissues showing the smallest percentage of trajectory changes, and the liver and testis showing the largest. Our work provides a resource of developmental transcriptomes of seven organs across seven species, and comparative analyses that characterize the development and evolution of mammalian organs.

TL;DR: Molpro as mentioned in this paper is a general purpose quantum chemistry software package with a long development history, originally focused on accurate wavefunction calculations for small molecules but now has many additional distinctive capabilities that include, inter alia, local correlation approximations combined with explicit correlation, highly efficient implementations of single-reference correlation methods, robust and efficient multireference methods for large molecules, projection embedding, and anharmonic vibrational spectra.

It was originally focused on accurate wavefunction calculations for small molecules but now has many additional distinctive capabilities that include, inter alia, local correlation approximations combined with explicit correlation, highly efficient implementations of single-reference correlation methods, robust and efficient multireference methods for large molecules, projection embedding, and anharmonic vibrational spectra. In addition to conventional input-file specification of calculations, Molpro calculations can now be specified and analyzed via a new graphical user interface and through a Python framework.
