A micro- and mesoporous carbon obtained from cherry pit waste and activated with HBPO4 acid has been studied as the sulfur host for Li/S batteries. The carbon has a high specific surface area of 1,662 m2·g-1 （SBET） and micropore and mesopore volumes of 0.57 and 0.40 cm3·g-1, respectively. The S/C composite, with a sulfur content of 57% deposited by the disproportionate reaction of a SaO2- solution in an acid medium without an additional heating step above the S melting point, delivers an initial specific capacity of 1,148 mah·g-1 at a current of C/16. It also has a high capacity retention of 915 mAh·g-1 after 100 cycles and a Coulombic efficiency close to 100%. The good performance of the composite was also observed under higher current rates and long-term cycling tests. The capacities delivered by the cell after 200 cycles were 707 and 410 mAh·g-1 at C/2 and 1C （1C = 1,675 mA·g-1）, respectively, maintaining the high Coulombic efficiency. The overall electrochemical response of this carbon as the sulfur matrix is among the best reported so far among the other biomass-derived carbons, probably because of the micro- and mesopore system formed upon activation.

Apicomplexa are an extremely diverse group of unicellular organisms that infect humans and other animals. Despite the great advances in combating infectious diseases over the past century, these parasites still have a tremendous social and economic burden on human societies, particularly in tropical and subtropical regions of the world. Proteases from apicomplexa have been characterized at the molecular and cellular levels, and central roles have been proposed for proteases in diverse processes. In this work, 16 new genes encoding for trypsin proteases are identified in 8 apicomplexan genomes by a genome-wide survey. Phylogenetic analysis suggests that these genes were gained through both intracellutar gene transfer and vertical gene transfer. Identification, characterization and understanding of the evolutionary origin of protease-mediated processes are crucial to increase the knowledge and improve the strategies for the development of novel chemotherapeutic agents and vaccines.

Humanity is in the grip of another pandemic beyond coronavirus disease(COVID).Although it is not spreading as rapidly as the viral pandemic,it is insidious and probably presents a greater threat in the long *** the large-scale use of antibiotics,we have driven the emergence of antimicrobial resistance(AMR)in bacteria,and these resistant bacteria are increasing in number and prevalence,threatening our ability to treat common infections and reducing our opportunities to use other life-saving treatments such as chemotherapy and surgery.A recent study showed that bacterial AMR was associated with nearly 5 million deaths in2019,with about 1.3 million being directly attributable to resistance[1].These numbers are likely to increase.

The Asian Network on Climate Science and Technology （***）, in collaboration with Tsinghua University, held a conference on environmental and climate science, air pollution, urban planning and transportation in July 2015, with over 40 Asian experts participating and presentation. This was followed by a meeting with local government and community experts on the practical conclusions of the conference. Of the papers presented at the conference a selection are included in this special issue of ]ournal of Environmental Science, which also reflects the conclusions of the Paris Climate meeting in Dec 2015, when the major nations of the world agreed about the compelling need to reduce the upward trend of adverse impacts associated with global climate change. Now is the time for urban areas to work out the serious consequences for their populations, but also how they should work together to take action to reduce global wanning to benefit their own communities and also the whole planet!

In the final essay of this series the gaps between biology and engineering are examined, and methods are suggested for crossing them. Creativity is seen as the essential, and TRIZ （the Russian Theory of Inventive Problem Solving） is recommended as the best set of methods both for stimulating creativity and for solving technical problems. When the catalogue of Inventive Principles of TRIZ is used to bring biology and technology to the same level of detail, the comparison shows that the similarity is only about 12%. The differences largely reside in the reliance of energy as a controlling parameter in conventional technology and the replacement of energy by information in biological systems. Although we might be moving slowly in this direction, a numerically based comparison such as this should provide more impetus.
