Since the discovery of graphene and the rise of MoS2, atomically thin two-dimensional （2D） crystals have grown into a huge family of materials ranging from semimetal, semiconductors to insulators. Monolayer transition-metal dichalcogenides denoted as MX2 （e.g., M=Mo, W, and X=S, Se, Te） have been prepared by physical exfoliation and chemical vapor deposition,
In our conversation with Prof. CHEN Lingling on the ＂dark matter＂ in the genome, namely the non-coding RNAs, we got to know two classes of long non-coding RNAs （IncRNAs） in close association with Prader-Willi syndrome （PWS）.
The knowledge of how atoms （or molecules） move is crucial for understanding the state of a material, and the existence of a decoupling of relaxation modes on cooling supercooled liquids has for instance dramatically improved our knowledge on the ongoing processes responsible for the vitrification and deformation. However, the movement of atoms in glasses - very thick liquids that move extremely slowly, are extremely to model just as the process of geological evolution in nature, as their relaxation time is incredibly long.
How can you tell whether or not a research area is on the frontier of a science subject？ Particularly, as an ＂outsider＂ - one who is not working in a certain research area, how do you evaluate how ＂new＂ or how ＂advanced＂ it is？
In this era of colossal data, more than 2 quintillion bytes of data were created every day. The huge amount of data brings us not only unprecedented convenience and opportunities but also incomparably severe challenges in data processing at the same time. The processing performance of computers is known to be determined almost entirely by the logic devices. However, the traditional strategy that aims at miniaturization of logic devices to increase the density of integration is going to encounter a ceiling set by the physical and lithographic restrictions.
Ten years ago, in 2007, tile Chinese Academy of Sciences gave out its lirst Award for International Scientific Cooperation to two distinguished foreign scientists： circulating fluidized bed expert Lothar Reh from the Swiss Federal Institute of Technology, and agricultural economist Scott Douglas Rozelle from Stanford University. Dr. Reh＇s relationship with China started in tile early 1970s, when he first visited the country to foster a cooperative link between the Lurgi Group and China.
It is well known that embryonic stein cells can self-renewal unlimitedly and differentiate into all .cell types of an organism in vitro, having broad applications for future organ regeneration and cell replacement therapy. However, there are still many questions about the molecular regulation of self-renewal and pluripotency in hESCs. Therefore, it is important to study the mechanism by which hESCs maintain their own characteristics.
＂Here we report a direct measurement of cosmic-ray electrons and positrons in the energy range 25 gigaelectronvolts to 4.6 teraelectronvolts ...＂ The Dark Matter Particle Explorer （DAMPE）, also known as ＂Wukong＂ in Chinese,
Cyclophilin A （CypA, encoded by PPIA） is a pepiidyl-prolyl cis/trans isomerase （PPlase） that is expressed ubiquitously in all type of cells. CypA is the major cellular target for the immunosuppressive drug cyclosporin A （CsA） and is involved in protein folding, cell signaling, inflammation, and tumorigenesis. Recent work suggests that it also plays a role in regulating virus replication.
Hardly had the elation in the wake of the 1,200 km-survival of quantum entanglement subsided before we again had news from Micius.On August 10,the joint team reported online in Nature the results from the other two major experiments aboard the satellite:Both the encrypted quantum key distribution(QKD)and quantum teleportation(QT)successfully passed through a distance of approximately 1,200 km,and did so less than
The United Nations＇ 2030 Agenda for Sustainable Development, or ＂Agenda 2030＂, is a blueprint for the future wellbeing of humankind. Particularly, it is underpinned by 17 Sustainable Development Goals （SDGs）, which are further derived into 169 specific targets.
In the middle of May,2017,Professor Ar thur B.McDonald,director of the Sudbury Neutrino Observatory(SNO)in Canada and Nobel Prize Laureate in Physics in 2015,visited the Institute of High Energy Physics(IHEP),Chinese Academy of Sciences(CAS).After a brief visit to the laboratories for particle physics at IHEP,he shared his opinions on the future of neutrino physics,neutr ino exper iments,and other large scienti f ic faci l ities in China and worldwide.
While foraging, animals can form inter- and intra-specific social signaling （i.e.one organism using signals to alert another about danger）networks to avoid similar predators. Honey bee sting alarm pheromones are multi-component blends, for instance isopentyl acetate （IPA）, octyl acetate （OA）, benzyl acetate （BA）,
It is a hot summer morning amid the endless greenness of lychee orchards 30 km southeast .of downtown Dongguan, near China＇s southern coastline, when project manager CHEN Hesheng and his team gathered with excitement in the control room of the China Spallation Neutron Source （CSNS） to witness a historic moment： the production of the first neutron beam lines from the machine they had just completed after more than six years of construction.
Male infertility, an issue that has aroused global concern in an era marked with ageing ,population and low birthrate, to a large extent results from decreased quantity and worsened quality of sperm, according to experts. An extreme case is idiopathic azoospermia, a medical condition featuring no sperm in semen. This remains an obstinate disease that has perplexed scientists, as its underlying mechanisms are far from clear and hence no well- targeted treatment strategy is available, let alone any effective therapy or medicine.
China＇s ambition to build a 12 m aperture optical/ infrared telescope in Tibet has been recently challenged by intense disputes over its design options. The Large Optical/Infrared Telescope, or LOT, which will become the world＇s biggest upon completion before the 30 m-level ones are in place, is expected to give Chinese astronomers a head start in exploring the early universe and exoplanets among other scientific goals. However, optical engineers and scientists are holding on to very different opinions as for what is the best technical route to get there.
Swarming widely occurs in the animal kingdom. Colonial individuals usually change their behaviors to adapt environmental variation, thus displaying distinguish behavioral plasticity. A series of neuromodulators have been implicated in behavioral regulation. Nevertheless, the molecular mechanisms by which these factors shape behavioral plasticity in swarming animals is poorly understood.
The pterosaur record is generally poor, and pterosaur eggs are even rarer. Only a handful of isolated occurrences of eggs and embryos have been reported so far. Three-dimensionally preserved eggs include one from Argentina and five reported from the Turpan-Hami Basin, Xinjiang, northwestern China in 2014.
