CAS Ocean Research Institute solves genome of shrimp

A team led by Jianhai XIANG and Fuhua LI solved the genome of shrimp (Penaeus vannamei) and obtained a high-quality shrimp genome reference map. Decapod crustaceans contain a large number of important aquatic species, such as shrimp, crab, lobster, etc., and Litopenaeus vannamei is the first among the four cultured shrimps, with an annual output of 4.16 million tons. Prawns have a highly developed vision system, a pair of compound eyes that connect freely moving eye stalks. Each compound eye contains about 5.5-8 million small eyes resulting in a wide viewing angle. Comparative genomics analysis revealed that the long-wavelength opsin gene in the shrimp genome is significantly expanded, which may be related to the organism’s adaptation to the dark benthic environment. The nerve conduction velocity of shrimps is 200 ms-1, the fastest among reported species. A large number of gene families related to nerve signaling are significantly expanded, especially, glutamate and glycine receptors.

Chang’e-4’s lunar lander sprouted cotton-seeds for 9 days

In an experiment to popularize space science, sprouting cottonseed was taken up to the moon by China’s Chang’e-4 Lunar Exploration Program on January 3. The payload has a heating system which kept the seed warm for sprouting. When the payload turned off after the Chang’e-4 lander entered sleep mode to save energy on January 13, the plant died quickly of extreme cold. During the 212.75 hours from power-on to power-off, the payload worked well. Some of the results exceeded expectations, as explained by XIE Gengxin, the payload’s designer and dean of Chongqing University’s Institute of Advanced Technology. The payload transmitted more than 170 pictures back to the Earth.

Xuan paper: a Chinese heritage made fire-resistant and durable for several thousand years

Xuan paper is a unique high-quality paper originating in ancient China. It is considered the best material for the calligraphy and painting andhas a reputation as “the king of paper that lasts for 1000 years”. 2009 it came on the UNESCO list of Intangible Cultural Heritage of Humanity. Xuan paper is produced only in Anhui province from the bark of Pteroceltis tatarinowii, a common species of elm, with limestone particles deposited on the surface which can neutralize acids produced by the hydrolysis of plant fibers and from the environment. A team around ZHU Yingjie from CAS Shanghai Institute of Ceramics now developed an improved kind of “fire-resistant Xuan paper” based on ultralong hydroxyapatite nanowires used as the main building material and micrometer-sized silica glass fibers as the reinforcing framework material. In addition, a new kind of inorganic adhesive composed of amorphous nanoparticles was added. The production process is simple, highly efficient, and needs only 3~4 days. The original whiteness of the new Xuan paper was 92%, and whiteness retention was 94.2 % after simulated aging for 3000 years. When exposed to different kinds of mould spores, even in the presence of nutrients, they did not grow. The most important property is, however, that the new Xuan paper is fire resistant and exhibits high thermal stability.CAS news release, January 18, 2019

Genome editing may lead to improved vascular cells

A team from CAS Institute of Biophysics, Institute of Zoology and Peking University has prepared human vascular cells with improved self-renewal and increased resistance to oxidative injury. In human ESC-derived vascular cells, they engineered FOXO3, an evolutionarily conserved longevity factor, to a more stable homolog by replacing two nucleotides in exon 3 of the FOXO3 gene that inhibit the phosphorylation and subsequent nuclear export and degradation of FOXO3, thus promoting the nuclear translocation of the FOXO3 protein and expression of its target genes. When tested in a therapeutic context in a mouse model, these cells promoted vascular regeneration of ischemic injury and were resistant to tumorigenic transformation both in vitro and in vivo. Mechanistically, constitutively active FOXO3 conferred cytoprotection by transcriptionally downregulating CSRP1. The study is seen as a promising option for future regenerative medicine.

Baidu presents AI-based language recognition software which responds to dialects

The software is based on Multilayered Attention Modeling (SMLTA) which has increased the accuracy of on-line voice authentication by 15%. Current input software is mainly used for mobile terminals, but in the future it will be applied to interaction between various smart devices and users. With the progress of voice input technology that mixes Chinese, English and dialect, users will realize “free talk”, even if Chinese and English are mixed, or if Mandarin is changed to home dialects. Baidu’s overseas input software also allows for Japanese identification, Hindi recognition, and has an Hindi-English mixed input function.

High-purity hydrogen from an electrochemical shift reaction: CAS Dalian Institute of Chemical Physics

The team around DENG Dehui has found a new way for a highly energy-efficient conversion of water to hydrogen at room temperature by using an electrochemical vapor shift reaction. Water vapor shift reaction (CO + H2O → H2 + CO2) is the main method for industrially producing hydrogen on a large scale. However, the process is carried out at high temperature (180 ° C – 250 ° C) and high pressure (1.0 – 6.0 MPa). DENG’s team opted for an electrochemical method: CO is oxidized at a Pt/Cu anode, and the generated CO2 reacts with KOH to form potassium carbonate; at the cathode, water is directly reduced to high-purity hydrogen with nearly 100 % Faraday efficiency. Current density reached 70mA/cm2 at 0.6V, and the catalyst was highly active for 475 hours.

China’s Chang’e moon probe will carry out biosphere experiments

Professor XIE Gengxin of Chongqing University said a canister installed on the probe contained the seeds of cotton, rapeseed, potato, and arabidopsis, as well as eggs of fruit fly and some yeast, to form a simple mini biosphere. After Chang’e-4 landed on Jan. 3, ground control initiated to water the plants, and a tube directs natural light on the surface of the moon into the canister to allow the plants to grow. Images sent by the probe so far showed that a cotton sprout had started to grow, though no other plants were found growing. According to XIE, potatoes could be a major source of food for future space travelers. The growth period of Arabidopsi, is short and easy to observe. Yeast could play a role in regulating carbon dioxide and oxygen in the mini biosphere, and the fruit fly would be the consumer of the photosynthesis process.
