China to launch deep earth exploration plan
(People's Daily Online) 15:06, September 06, 2016

China has announced plans to launch a deep earth exploration plan, which, in addition to deep earth exploration, also includes deep sea exploration and space-borne earth observation. The plan was outlined in a report entitled "Development Planning of Territorial Resources for Scientific Innovation During the 13th Five-Year Plan," issued recently by the Ministry of Land and Resources.

"Just 2 percent of the resources from between 3 and 10 kilometers beneath Chinese territory could be enough for us to use for over 5,000 years," said Dong Shuwen, former deputy director of the Chinese Academy of Geological Sciences, at the National Land and Resources Scientific Innovation Conference on Sept. 5.

In the next five years, China will conduct surveys of urban underground space utilization, underground water-bearing and more in order to evaluate the potential resources and prospects of Chinese cities' underground territory.

The effective utilization of underground space has been going on for many years already in some developed countries. Singapore and Japan utilize space up to 200 meters below ground. However, China's current average utilization is less than 50 meters; this means that in most cities, there are at least 150 meters of space yet to be exploited.

"In many countries, the utilization of underground spaces is diversified, spanning culture, communication, transportation and ecology," said Dong.

By 2020, China's strategic exploration targets include mining ability at 2 kilometers underground, the technology to conduct mineral resources prospecting at 3 kilometers underground, advanced technology to explore resources at 5 kilometers underground and the improvement of oil and gas exploration at between 6.5 and 10 kilometers underground. Meanwhile, the prospecting depth for oil and gas exploration will reach 10 kilometers underground, and new energies such as terrestrial heat will be exploited.

Chemistry method expedites path to useful molecules for medicine
University of Wisconsin-Madison

MADISON, Wis. -- Opening a broad vista in the search for effective pharmaceuticals, a collaboration of Chinese and U.S. chemists has laid out a highly efficient new method to convert abundant organic molecules into new medicines.

Writing Sept. 2 in the journal Science, teams led by Guosheng Liu of the Shanghai Institute of Organic Chemistry (SIOC) and Shannon Stahl of the University of Wisconsin-Madison describe a way to convert carbon-hydrogen bonds into nitriles, common components of bioactive molecules used in medicinal and agricultural applications.

Carbon-hydrogen bonds are the most common feature of the molecular building blocks used to make valuable chemicals. The new method will help break the stranglehold of carbon-hydrogen bonds present in the chemical feedstocks used to make bioactive molecules. Exchanging hydrogen atoms in such molecules for more useful elements is difficult without damaging or destroying the rest of the molecule. The new method described by Liu and Stahl gives chemists prospecting for bioactive molecules a new tool in the search for novel drugs or chemicals for agriculture.

"We need more efficient ways to convert feedstocks into useful molecules," explains Stahl, a UW-Madison professor of chemistry. "Selective functionalization of carbon-hydrogen bonds is one of the holy grails of modern chemistry."

Although chemists have ways of making biologically active molecules now, the current routes are often laborious and create large amounts of waste. The new method removes many of the intermediate steps and will make the process far easier for medicinal chemists.

An important feature of the new method is that it provides access to so-called chiral molecules that are a match for enzymes targeted in disease. Chiral molecules have mirror-image versions of themselves, similar to a pair of human hands. For drug molecules to be effective, they must fit -- like a hand into a glove -- the targeted molecular niche of an enzyme.

"The three-dimensional shape and chirality of molecules often correlates with the efficacy or potency of a pharmaceutical," notes Stahl.

The two mirror-image forms of drug molecules can have vastly different effects. An infamous example is thalidomide, first prescribed as a sedative in the 1950s. The reverse image of the molecule, however, was later linked to severe birth defects.

"It is important to be able to synthesize only one of two mirror images of the molecule, and development of new catalytic methods that achieve this goal, starting with carbon-hydrogen bonds, is highly desired," says Liu, a professor of chemistry at SIOC.

In their Science report, Liu, Stahl and colleagues Wen Zhang, Fei Wang, Dinghai Wang and Pinhong Chen of SIOC, and Scott McCann of UW-Madison, describe a very efficient strategy for the preparation of benzylic nitriles, which are precursors to broad classes of hormones, neurotransmitters, psychoactive and anti-inflammatory drugs.

Scientists developing multipurpose stratospheric airships
China Daily, 2016-09-07 08:48

Chinese scientists are developing a family of high altitude airships that can help with Earth observation, maritime monitoring and communication signal relays.

Researchers at the Chinese Academy of Sciences are working on the stratospheric airships, so-called because they are capable of conducting long-term operations in the stratosphere-the second major layer of Earth's atmosphere at an altitude of 20 to 50 km.

According to the academy's development plan for the 13th Five-Year Plan period (2016-2020), which lists 140 research and development priorities, researchers are to develop key technologies and techniques for controllable stratospheric airships and perform flight tests before the end of 2020.

"Our stratospheric airships will come in various sizes, and we have test-flown two of them already," said Wang Yuechao, director of the academy's Bureau of Major Research and Development Programs.

"The latest test took place in August, when we flew an airship and achieved our goals."

He said that almost all of the world's major powers are exploring high-altitude aerospace craft, with China among the top players in the field.

The academy's stratospheric airships can operate autonomously or be remotely controlled by ground personnel, according to earlier reports.

Solar-powered, reusable and unmanned, such vehicles can spend a long time aloft and serve a wide range of purposes. At least five nations, including the United States and Japan, are developing such systems.

Wang Ya'nan, editor-in-chief of Aerospace Knowledge magazine, said that compared with spacecraft and satellites, stratospheric airships do not need a launch pad and are convenient to retrieve and reuse. They also provide a wider view of the Earth and a much longer operational time than aircraft.

"Therefore, they provide a better platform for Earth monitoring and maritime surveillance," Wang said.

Moreover, because airships are closer to the Earth than satellites, they can act as a better hub for relaying communications signals.

"In addition, stratospheric airships are able to carry payloads that will be as much as 10 times that of a spacecraft," Wang said.

Zhu Ming, an associate professor at Beihang University in Beijing, said they could have many uses in the public sector.

"They have a lot of potential in environmental protection, disaster relief and weather forecasting," he said.

Sugar Transforms a Traditional Chinese Medicine into a Cruise Missile
Anticancer compound becomes more soluble and selective after glucose is attached

Release Date: September 7, 2016

Glutriptolides can act as “cruise missiles” against cancer. The glucose component targets glucose transporters (red) in the membrane of cells, pulling the toxic triptolide inside.
Johns Hopkins Medicine


More than 20 years ago, a billboard in China piqued the interest of a chemical biologist. It endorsed an extract from the plant known as the “thunder god vine” as an immunosuppressant. A brief review of published research revealed that the extract’s key ingredient — the small molecule triptolide — had been identified 20 years before that billboard ad, and it could stop cells from multiplying.

Now, that chemical biologist and his colleagues at the Johns Hopkins University School of Medicine report that tests of triptolide in human cells and mice are vastly improved by the chemical attachment of glucose to the triptolide molecule. The chemical add-on makes the molecule more soluble and essentially turns it into a “cruise missile” that preferentially seeks out cancer cells, the research says. The change might also decrease side effects in patients and make the drug easier to administer.

A summary of the research is published in the journal Angewandte Chemie and was published online on Aug. 30.

“We have a long way to go before we can test this derivative of triptolide in humans, and we think that additional adjustments could improve it even more,” says Jun O. Liu, Ph.D., professor of pharmacology and molecular sciences at the Johns Hopkins University School of Medicine and a member of the Johns Hopkins Kimmel Cancer Center, “but it already has the key characteristics we’ve been looking for: It is quite water soluble, and it prefers cancer cells over healthy cells.”

Liu, a native of a small town north of Shanghai in China, explains that the thunder god vine has been used in traditional Chinese medicine for more than 400 years, mostly to calm an overactive immune system, which can cause diseases like rheumatoid arthritis and multiple sclerosis.

His laboratory specializes in figuring out how natural compounds with known healing properties exert their effects on human cells. Five years ago, he and his colleagues discovered that triptolide halts cell growth by interfering with the protein XPB, part of the large protein machine transcription factor IIH, which, in turn, is needed by enzyme complex RNA polymerase II to make mRNA.

Because triptolide halts cell growth, it works well to fight the multiplication of cancer cells, Liu says, both in lab-grown cells and in laboratory animals with cancer. Unfortunately, it — and many of its derivatives — has failed to work well in patients because it doesn’t dissolve well in water or blood, and has too many side effects due to its indiscriminate killing of healthy cells as well as tumor cells.

Liu’s latest research sought to “train” triptolide to target cancer cells by exploiting the knowledge that most cancer cells make extra copies of proteins, called glucose transporters. Those transporters form tunnels through a cell’s membrane to import enough glucose to fuel rapid growth. By attaching glucose to triptolide, the researchers hoped to trick the cancer cells into importing the cell-killing poison, as had been done successfully with other anticancer drugs.

“We were looking for something that could be administered intravenously, remain stable in the blood and then become active as soon as it was imported into cancer cells,” says Liu.

To begin, the chemists designed and synthesized five derivatives of triptolide, dubbed glutriptolides. Each derivative had glucose attached to the same spot on the triptolide molecule but had different “linkers” connecting them.

An initial experiment showed that none of the glutriptolides were good at blocking the activity of purified transcription factor IIH. Liu explains that what might seem like bad news was actually a positive result, since it suggested that the drugs would only be active once they entered cells and had their glucose attachments removed.

When the five glutriptolides were tested on human embryonic kidney cells, glutriptolide 2 slowed down cell growth better than the rest and is the only derivative they continued to study.

In later test tube and cell experiments, the researchers confirmed that glutriptolide 2 works just like triptolide — by interfering with XPB — though it does so only in higher concentrations. They also showed that a cancer cell line (DLD1-Mut) known to produce lots of glucose transporter 1 was more sensitive to glutriptolide 2’s effects than a similar cell line (DLD1-WT) without extra copies of the transporter.

When the researchers assessed triptolide’s effects on a variety of healthy cells and cancer cells in parallel with glutriptolide 2, they found that triptolide tended to equally slow the growth of healthy cells and cancer cells, while glutriptolide 2 was eight times more effective against cancer cells, on average. Liu says this result suggests that the new compound — if tested in humans — may be more selective against cancer cells and could therefore have fewer side effects.

Finally, due to the differences in the compounds’ general toxicity, tests showed that mice could tolerate a dose of 0.2 milligram/kilogram of triptolide and 1 milligram/kilogram of glutriptolide 2. At those doses, glutriptolide 2 eradicated tumors more quickly in mice with prostate cancer and prevented tumor cells from reappearing for a full three weeks after treatment had stopped.

“We were totally surprised to see that sustained antitumor activity,” says Liu. “It’s something we want to study further.” The group plans to test additional modifications to the biochemical links that connect glucose to triptolide to see if it can further decrease the compound’s toxicity to healthy cells and increase its effectiveness against cancerous ones.

The work was accomplished through a close international collaboration among three research groups led by Liu, Martin Pomper of the Johns Hopkins University School of Medicine and Biao Yu of the Chinese Academy of Sciences. Other authors of the report include Qing-Li He, Il Minn, Sarah Head and Emmanuel Datan of the Johns Hopkins University School of Medicine, and Qiaoling Wang and Peng Xu of the Shanghai Institute of Organic Chemistry at the Chinese Academy of Sciences.

This work was supported by a Synergy Award from the Johns Hopkins University School of Medicine and the Johns Hopkins Institute for Clinical and Translational Research, which is funded in part by the National Center for Advancing Translational Sciences (UL1 TR 001079).

A nondisclosure agreement for the invention/technology described in this publication has been executed between The Johns Hopkins University and Rapafusyn Pharmaceuticals Inc. Dr. Liu is a co-founder of and a Scientific Advisory Board Member for Rapafusyn Pharmaceuticals Inc. This arrangement has been reviewed and approved by The Johns Hopkins University in accordance with its conflict of interest policies.

Study shows how Chinese medicine kills cancer cells
Thursday, 8 September 2016
clear.png


Researchers at the University of Adelaide have shown how a complex mix of plant compounds derived from ancient clinical practice in China – a Traditional Chinese Medicine – works to kill cancer cells.

Compound kushen injection (CKI) is approved for use in China to treat various cancer tumours, usually as an adjunct to western chemotherapy – but how it works has not been known.

This study, published in the journal Oncotarget, is one of the first to characterise the molecular action of a Traditional Chinese Medicine rather than breaking it down to its constituent parts.

“Most Traditional Chinese Medicine are based on hundreds or thousands of years of experience with their use in China,” says study leader, Professor David Adelson, Director of the Zhendong Australia – China Centre for the Molecular Basis of Traditional Chinese Medicine.

“There is often plenty of evidence that these medicines have a therapeutic benefit, but there isn’t the understanding of how or why.

“If we broke down and tested the components of many Traditional Chinese Medicines, we would find that individual compounds don’t have much activity on their own. It’s the combination of compounds which can be effective, and potentially means few side-effects as well.

“This is one of the first studies to show the molecular mode of action of a complex mixture of plant-based compounds – in this case extracts from the roots of two medicinal herbs, Kushen and Baituling – by applying what’s known as a systems biology approach. This is a way of analysing complex biological systems that attempts to take into account all measurable aspects of the system rather than focussing on a single variable.”

The Zhendong Australia China Centre for Molecular Traditional Chinese Medicine was established at the University of Adelaide in 2012 in a collaboration with the China-based Shanxi College of Traditional Chinese Medicine and Zhendong Pharmaceutical Company.

The Centre was established with a donation by the Zhendong Pharmaceutical Company, with the aim of understanding how Traditional Chinese Medicine works, and the long-term aim of possible integration into western medicine.

The researchers used high-throughput next generation sequencing technologies to identify genes and biological pathways targeted by CKI when applied to breast cancer cells grown in the laboratory.

“We showed that the patterns of gene expression triggered by CKI affect the same pathways as western chemotherapy but by acting on different genes in the same pathways,” says Professor Adelson.

“These genes regulate the cell cycle of division and death, and it seems that CKI alters the way the cell cycle is regulated to push cancer cells down the cell death pathway, therefore killing the cells.”

Professor Adelson says this technique could be used to analyse the molecular mechanisms of other Traditional Chinese Medicines, potentially opening their way for use in western medicine.

The Institute of Electrical Engineering under the Chinese Academy of Sciences announced on Sept. 9 that a research group led by Ma Yanwei has successfully developed the world’s first 100-meter, iron-based superconducting wire, which is a milestone in the research of iron-based superconducting materials.

Currently, the production of iron-based superconducting wire in the U.S., Japan and Europe falls short of 100 meters. However, manufacturing technology at the 100-meter level is key for the mass application of the material.

Ma's research group created the world's first iron-based superconducting wire in 2008. In 2010, they invented a special technology for welding, which laid a foundation for further improvement of the wire. In 2013, they made the world’s first high-performance iron-based, multi-filament superconducting wire; in 2014, they successfully developed the world's first 10-meter iron-based superconducting wire, taking the first step toward large-scale manufacturing.

More recently, the research team was finally able to get past the technological difficulties in large-scale manufacturing, producing a wire that is 115 meters long.

The successful development of this improved superconducting wire means that China possesses intellectual property that can be applied to medicine, national defense and many other industries.

Researchers Make New Progress in Understanding Genetic Basis of Heterosis in Rice
2016-09-09

On Sep 8, 2016 (Beijing time), Nature online published a research paper entitled “'Genomic architecture of heterosis for yield traits in rice” from Prof. HAN Bin’s group and Prof. HUANG Xuehui’s group of Institute of Plant Physiology and Ecology (SIPPE), Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, with the cooperation from Prof. YANG Shihua’s group of China National Rice Research Institute.

Improvement of grain yield is an on-going effort in crop breeding to meet the demand of global food security. Exploiting the heterosis phenomenon in hybrid crop breeding is one of the most efficient ways to increase grain yield in many crops including rice, maize and sorghum. However, the genetic cause of heterosis in crop has long been a puzzle despite that the heterotic phenomenon has been discovered for more than a century and various genetic models have been suggested to explain it.

This work report large-scale genomic mapping for yield related traits and evaluation of the heterotic effects by analyzing over 10,000 rice lines produced from 17 elite rice lines. The large data of genomics and phenomics from the well-designed populations enabled us, for the first time, to identify the genetic contributors comprehensively and find out the exact causes of heterosis. The researchers find that modern rice varieties can be classified into three major types, reflecting the major breeding systems. Within each group a few genomic regions and gene alleles from female parents linked to heterosis effects for improved yields were identified, but these loci varied across the three groups. The key heterosis-related genes often controlled several yield-related components simultaneously, severing as the major contributors of heterosis. For the individual yield components, the heterozygous state of the heterosis-related genes generally acted through the way of dominance complementation.

Taking all the components into account, the hybrids with yield heterosis resulted from an optimal combination of multiple yield-related components, meaning better performance of overall yield in crop productions.

These results inform on the genomic architecture of heterosis for yield traits in rice, which will be useful information for crop improvement programmes.

This project is financially supported by Chinese Academy of Sciences (XDA08020101) and the National Natural Science Foundation of China.

Air pollution is one of the most severe environmental problems in East Asia. But where does Asia's air pollution come from?

A study published recently in the journal Nature Geoscience revealed that most of East Asia's aerosol emissions are driven by consumption in the developed countries of Western Europe and North America. This marks the first time the climate effect of international trade had been calculated.

Researchers looked at a number of aerosols, tiny particles suspended in air, created through manufacturing and energy production.

"Our study revealed a strong, yet little-recognized link among consumption, trade and environmental and climate consequences," says co-author, atmospheric scientist Yi Huang in a press release. ''Although global pollution is largely generated in developing countries, it is foreign demand that drives much of the goods production and associated pollution.''

Super fast lasers that are out of this world
Update time: 09-09-2016

A machine has successfully demonstrated ultra-intense, ultra-fast lasers that can deliver peak power of more than five petawatts for the first time in the world, scientists said yesterday.

"The extreme physical conditions created by the laser pulses with petawatt level peak power exist mainly inside stars or edge of the black holes,” said Leng Yuxin, the laboratory head.

"With the laser beams we can create such extreme environments in a controllable scale within a laboratory, and help scientists in producing hyperfast X-ray source, finding new materials under extreme conditions and even detect dark matter.”

This advancement in laser technology can be projected to research in such fields as astrophysics; nuclear medicine, a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease; and material science, which involves the discovery and design of new materials.

The Shanghai Superintense-Ultrafast Lasers Facility, or SULF, is being developed by Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences.

Ultra-intense ultra-fast lasers, also known as the brightest light known to man, are capable of creating extreme physical conditions that rarely exist in the universe.

The director of SIOM, Li Ruxin, said the lasers offered broad and promising applications, such as making an impressive advancement in the running speed of smartphones.

The laser machine facility, located in ShanghaiTech University, is one of the core research platforms in Shanghai Zhangjiang High-Tech Park.

The developers are expected to deliver 10-petawatt lasers next year. One petawatt is equivalent to one quadrillion watts.The project’s three platforms to serve interdisciplinary application in material science and life science are expected to be put into operation by the end of 2018. They will be made available to research institutions and innovative companies around the world. (Shanghai Daily)
