Loongson is a general purpose RISC processor. It is a 64-bit MIPS compatible processor, which is patented by MIPS Technologies. The silicon is designed by ICT/CAS China and manufactured by ST Microelectronics. The online retail price for Loongson-2F chip is about USD30~40, which is available from the Lemote’s online shop. Of course, you can order it in the name of STLS2F from ST as well.

Loongson-2F, the latest version operates at 1.2 to 1.5GHz and only consumes 5 watts. Additionally, Loongson-2F also supports DDR2 and USB2.0. As a RISC processor, Loongson processor is struggling on its way to the market for a long time. As we know, the processor market is highly competitive. ARM has been a de facto standard RISC processor IP in mobile terminals and embedded SoC. MIPS is not the market leader. It is mainly used in digital video and telecommunication segments like STB, HDTV, IPTV, DSL modem, laser print and video game consoles (Sony PS/PSP). MIPS processors are usually available in IP and embedded SoC, you can find some old types available for legacy SGI workstation, Windows CE PPC and HPC. AMD acquired Alchemy MIPS processor in PMP and HDTV, and finally it got rid of this business line before long. Sometimes, I wonder why AMD bought Alchemy at the very beginning.

Although it is hard to find the market opportunities for MIPS. ICT offers a series of open source MIPS based designs for NAS, Linux desktop PC, thin client terminal and others with their own Loongson processor family. Recently, they start to promote the MIPS Netbook to the consumer market. The price is comparable to the ATOM/Nano based Netbook, many local Linux developers enjoy it very much. Because it is very hard to buy a high speed MIPS board with low price. Can you find a 300USD evaluation board for 1.5GHz MIPS processor? The system has been installed with Debian MIPS distribution and native GCC for MIPS. Compare to an ordinary x86 Netbook, the user experience is same. MIPS still have major OS support from Windows CE and Linux. Most of the popular software components are available on these platforms. Netbook and MID are great chances for MIPS to return to the desktop/mobile computing market. However, I can name many limitations for MIPS: you can not play Real Video and QuickTime, you can not run WINE, you can not use commercial DLLs for x86 and Windows, and you may face to the driver issues. The MIPS Netbook only fits the requirements for the highly experienced communities or the people who have no PC experiences at all (like my parents) and just want to check their emails or browsing. The MIPS device is good for them because it is totally virus-free.

I don’t want to promote MIPS IP or Loongson Netbook here. I also don’t think MIPS Netbook can win the market. Non-x86 structure can not beat x86 in Netbook, because people consider Netbook a low-cost laptop PC. However MIPS should focus its advantage on digital video segments, including media adapter, PMP and PND. And so we, as the engineers, let us check the specification and find out its opportunities.

– MIPS-III 64 bit superscalar architecture
– 900 MHz clock frequency
– Single/double precision floating point units
– New streaming multimedia instruction set support (SIMD)
– 64 KB I-cache, 64KB D-cache, on-chip 512 KB unified L2 cache
– On chip DDR2 667 and PCI-X controller
– 4W@900MHz power consumption:
– Voltage/frequency scaling
– Standby mode support
– L2 cache disable/enable option
– 90 nm process technology
– JTAG interface

Apparently, this chip has advantage on 64-bit performance, FPU, SIMD over mainstream ARM products. Meanwhile it has much lower power consumption over x86 processor. It requires 3rd party north/south bridges (VIA) to complete the system design. A Chinese company HiSand also developed a Loongson-1 based SoC for Internet Radio, digital photo frame and other consumer products. Its HS3210 has integrated a lot of peripherals on-chip with a 266MHz MIPS core. It is the first step of the right direction. Only if its MIPS SoC wins the market, the Loongson can live on. I have no doubt about the market capacity of consumer electronics, if HS3210 has good quality with low price as they claimed, it is make sense to buy a Loongson computer/Netbook for development purpose with the native toolchains. Loongson also offers a simulator so you can evaluate the system.

WASHINGTON — The following is a statement about the European Southern Observatory’s latest exoplanet discovery from NASA’s Science Mission Directorate Associate Administrator, Dr. John Grunsfeld. (from nasa.gov release : 12-366)

“We congratulate the European Southern Observatory team for making this exciting new exoplanet discovery. For astronomers, the search for exoplanets helps us understand our place in the universe and determine whether Earth is unique in supporting life or if it is just one member of a large community of habitable worlds. NASA has several current and future missions that will continue in this search.

An example [sic] is NASA’s Kepler mission. It was specifically designed to survey a specific region of our Milky Way galaxy to detect Earth-size and smaller planets in or near the habitable zone — that region around a star where it is theoretically possible for a planet to maintain liquid water on its surface — and determine the fraction of the hundreds of billions of stars in our galaxy that might have such planets. Kepler works very differently from HARPS. Rather than detecting the wobble in the host star, Kepler detects the slight dimming of a star when a planet passes in front of it.

NASA’s Hubble and Spitzer space telescopes have contributed to the study of exoplanets. Using their photometric and spectroscopic sensitivity, these space telescopes have made the first steps in characterizing the atmospheres of planets around other stars. They can only do this when the exoplanets pass serendipitously in front of its star, allowing the space telescope to study light that has filtered through the planet’s atmosphere.

NASA’s James Webb Space Telescope (JWST) will provide a unique facility that will serve through the next decade as the mainstay for characterization of transiting exoplanets. The main transit studies JWST will be able to undertake are: discovery of unseen planets, determining exoplanet properties like mass, radius, and physical structure, and characterizing exoplanet atmospheres to determine things like their temperature and weather. If there are other planets in the Alpha Centauri system farther from the star, JWST may be able to detect them as well through imaging.

NASA is also studying two medium-class exoplanet missions in our Explorer program, and in the spring of 2013 will select one of them to enter development for flight later in the decade.”

Warning against the temptation “to play God,” President Clinton yesterday banned federal funding of human cloning research and asked privately funded scientists to halt such work until a national bioethics commission reviews what he called the “troubling” legal and ethical implications.

“Each human life is unique, born of a miracle that reaches beyond laboratory science,” Clinton said during a brief ceremony in the Oval Office, where he announced his executive directive. “I believe we must respect this profound gift and resist the temptation to replicate ourselves.”

The president’s order, effective immediately, comes 10 days after Scottish scientists reported they had cloned a sheep named Dolly from adult cells and two days after researchers in Oregon revealed they had bred a pair of rhesus monkeys from cloned embryo cells.

In 1994, Clinton signed an executive order banning federal funding of certain kinds of research involving human embryos, and Congress has prohibited other kinds of human embryo research. However, said Clinton yesterday, “after reviewing these restrictions, our administration believes that there are loopholes that could allow the cloning of human beings if the technology were developed.”

The president acknowledged that much of the cloning-related research in this country is conducted by private companies not covered by the federal ban. Some biotechnology companies are trying to clone pigs with humanized organs for transplantation into people, for example, and other companies have cloned goats that make human medicines in their milk. Clinton said he supported continued research in animals, but he asked companies to impose upon themselves a “voluntary moratorium” on expanding that work to humans.

“Any discovery that touches upon human creation is not simply a matter of scientific inquiry. It is a matter of morality and spirituality as well,” Clinton said. “That is why I am urging the entire scientific community — every foundation, every university, every industry that supports work in this area — to heed the federal government’s example.”

Highlighting the ban’s importance, Clinton made the announcement flanked by Vice President Gore, Health and Human Services Secretary Donna E. Shalala, National Institutes of Health Director Harold E. Varmus, presidential science adviser Jack Gibbons and Princeton President Harold T. Shapiro, who chairs the National Bioethics Advisory Commission. That commission is scheduled to meet at the Watergate Hotel on March 13 and 14 to discuss the ethics of human cloning and has been asked by the president to submit a final report on the issue by the end of May.

Many scientists, including those involved in cloning research, have insisted repeatedly during the past week that they have no interest in cloning humans, even if it were technically possible. After hearing of the president’s ban, several reiterated those feelings.

“The president’s reaction is a prudent one and is fully appropriate, and speaking for the industry, we support him wholeheartedly,” said Carl B. Feldbaum, president of the Biotechnology Industry Organization, which represents 700 biotechnology companies and institutions.

Feldbaum said it was understandable that Clinton, and probably much of the public, felt a need to put the brakes on the quickly evolving scientific field. “You go from cloning of sheep a week ago and you cloned monkeys this week and you figure humans have got to be cloned by next week,” he said.

Feldbaum said he was heartened, however, to see Varmus by Clinton’s side in the Oval Office — an arrangement he said indicated Clinton’s ongoing support for basic research on embryos, which could lead to improved treatments for infertility and other medical problems.

Colin Stewart, a researcher at the National Cancer Institute’s research center in Frederick, Md., said he too was encouraged by Clinton’s apparent effort not to reject all genetics research as he placed limits on human cloning.

“What I’ve been encouraged by in all this has been the level of debate and the high level of consciousness of what’s going on,” Stewart said, “and I hope this won’t stymie debate about long-term policy on human embryos and other forms of mammalian research.”

Rep. Constance A. Morella (R-Md.), whose district includes the NIH, has called for the first congressional hearings on cloning, to be held this afternoon in the Rayburn House Office Building. Scheduled speakers include Varmus, Case Western Reserve University bioethicist Thomas H. Murray; M. Susan Smith, director of the Oregon research center where the monkeys were cloned; and James Geraghty, president of Genzyme Transgenics, a Massachusetts company that has produced goats from cloned embryos.

Sen. Bill Frist (R-Tenn.) announced yesterday that his hearings on cloning, scheduled for next Wednesday in the Dirksen Senate Building, will include testimony from Ian Wilmut, the Scottish researcher who oversaw the cloning of Dolly.

The third and fourth satellites of Europe’s Galileo global navigation satellite system were lofted into orbit on 12 October from Europe’s Spaceport in French Guiana. They join the first pair of satellites launched a year ago to complete the validation phase of the Galileo programme. ( from esa.com )

The Soyuz ST-B launcher, operated by Arianespace, lifted off at 18:15 GMT (20:15 CEST) from the Guiana Space Centre. All the stages of the Soyuz vehicle performed as planned and the Fregat-MT upper stage released the Galileo satellites into their targeted orbit at close to 23 200 km altitude, 3 hours 45 minutes after liftoff.

Galileo is Europe’s own global satellite navigation system. It will consist of 30 satellites and their associated ground infrastructure. The definition, development and IOV phase of the Galileo programme are carried out by ESA, and co-funded by ESA and the European Commission. This phase leads to a mini-constellation of four satellites and a reduced ground segment dedicated to the validation of the overall concept.

These satellites launched were built by a consortium led by Astrium as prime contractor, with Thales Alenia Space in charge of assembly, integration and testing. The operations are managed by SpaceOpal a joint company of the DLR German Aerospace Center and Italy’s Telespazio, with the early operations of the satellites controlled by a joint ESA and CNES French space agency team in Toulouse, France.

After initial checks, they will be handed over to the Galileo Control Centres in Oberpfaffenhofen, Germany, and Fucino, Italy, for testing before they are commissioned for the Galileo service validation phase. From a performance point of view, these In-Orbit Validation (IOV) satellites are the same as the forthcoming satellites.

With four identical satellites now in orbit, ESA will be able to demonstrate the performance of the Galileo positioning system fully before the deployment of the remaining operational satellites.

“Since the first launch a year ago, Galileo’s technology has proven itself in orbit,” said Didier Faivre, ESA’s Director of the Galileo Programme and Navigation-related activities.
“Thanks to the satellites launched today, the testing phase will be completed, and clear the way for rapid full-scale deployment of the constellation.

“By late 2014, 18 satellites are scheduled to have been launched, by which time early services to Europeans can begin.” Galileo’s Full Operational Capability (FOC) will be reached with 30 satellites (including the four IOVs and in-orbit spares) in 2018.

The four satellites launched during the IOV phase are the nucleus of the constellation that will then be extended to reach its FOC.

The FOC phase is fully funded by the European Commission. The Commission and ESA have signed a delegation agreement by which ESA acts as design and procurement agent on behalf of the Commission.

Scientists have developed an artificial womb that allows embryos to grow outside the body  ( released 2002. from observer.co.uk)

Doctors are developing artificial wombs in which embryos can grow outside a woman’s body. The work has been hailed as a breakthrough in treating the childless. Scientists have created prototypes made out of cells extracted from women’s bodies. Embryos successfully attached themselves to the walls of these laboratory wombs and began to grow. However, experiments had to be terminated after a few days to comply with in-vitro fertilisation (IVF) regulations. ‘We hope to create complete artificial wombs using these techniques in a few years,’ said Dr Hung-Ching Liu of Cornell University’s Centre for Reproductive Medicine and Infertility. ‘Women with damaged uteruses and wombs will be able to have babies for the first time.’ The pace of progress in the field has startled experts. Artificial wombs could end many women’s childbirth problems – but they also raise major ethical headaches which will be debated at a major international conference titled ‘The End of Natural Motherhood?’ in Oklahoma next week. ‘There are going to be real problems,’ said organiser Dr Scott Gelfand, of Oklahoma State University. ‘Some feminists even say artificial wombs mean men could eliminate women from the planet and still perpetuate our species. That’s a bit alarmist. Nevertheless, this subject clearly raises strong feelings.’ Liu’s work involves removing cells from the endometrium, the lining of the womb. ‘We have learnt how to grow these cells in the laboratory using hormones and growth factors,’ she said. After this Liu and her colleagues grew layers of these cells on scaffolds of biodegradable material which had been modelled into shapes mirroring the interior of the uterus. The cells grew into tissue and the scaffold dissolved. Then nutrients and hormones such as oestrogen were added to the tissue. ‘Finally, we took embryos left over from IVF programmes and put these into our laboratory engineered tissue. The embryos attached themselves to the walls of our prototype wombs and began to settle there.’ The experiments were halted after six days. However, Liu now plans to continue with this research and allow embryos to grow in the artificial wombs for 14 days, the maximum permitted by IVF legislation. ‘We will then see if the embryos put down roots and veins into our artificial wombs’ walls, and see if their cells differentiate into primitive organs and develop a primitive placenta.’ The immediate aim of this work is to help women whose damaged wombs prevent them from conceiving. An artificial womb would be made from their own endometrium cells, an embryo placed inside it, and allowed to settle and grow before the whole package is placed back in her body. ‘The new womb would be made of the woman’s own cells. so there would be no danger of organ rejection,’ Liu added. However, her research is currently limited by IVF legislation. ‘The next stage will involve experiments with mice or dogs. If that works, we shall ask to take our work beyond the 14-day limit now imposed on such research.’ A different approach has been taken by Yoshinori Kuwabara at Juntendo University in Tokyo. His team has removed foetuses from goats and placed them in clear plastic tanks filled with amniotic fluid stabilised at body temperature. In this way, Kuwabara has kept goat foetuses alive and growing for up to 10 days by connecting their umbilical cords to machines that pump in nutrients and dispose of waste. While Liu’s work is aimed at helping those having difficulty conceiving, Kuwabara’s is designed to help women who suffer miscarriages or very premature births. In this way Liu is extending the time an embryo can exist in a laboratory before being placed in a woman’s body; Kuwabara is trying to give a foetus a safe home if expelled too early from its natural womb. Crucially, both believe artificial wombs capable of sustaining a child for nine months will become reality in a few years. ‘Essentially research is moving towards the same goal but from opposite directions,’ UK fertility expert Dr Simon Fishel, of Park Hospital, Nottingham, said. ‘Getting them to meet in the middle will not be easy, however. There are so many critical stages of pregnancy, and so many factors to get right. Nevertheless, this work is very exciting.’ It also has serious ethical implications, as Gelfand pointed out. ‘For a start, there is the issue of abortion. A woman is usually allowed to have one on the grounds she wants to get rid of something alien inside her own body. ‘At present, this means killing the foetus. But if artificial wombs are developed, the foetus could be placed in one, and the woman told she has to look after it once it has developed into a child.’ In addition, if combined with cloning technology, artificial wombs raise the prospect that gay couples could give ‘birth’ to their own children. ‘This would no doubt horrify right-wingers, while the implications for abortion law might well please them,’ he added. Gelfand also warned that artificial wombs could have unexpected consequences for working women and health insurance. ‘They would mean that women would no longer need maternity leave – which employers could become increasingly reluctant to give. ‘It may also turn out that artificial wombs provide safer environments than natural wombs which can be invaded by drugs and alcohol from a mother’s body. Health insurance companies could actually insist that women opt for the artificial way. ‘Certainly, this is going to raise a lot of tricky problems.’

Pieces of jewellery, pottery and iron tools dating back thousands of years have been discovered in Senegal’s capital, Dakar, following recent floods, researchers say. (from bbc.co.uk)

The ancient objects were found in an area where a house is being built

The discovery was made at a construction site, local academic Alioune Deme told the BBC. A colleague, Moustapha Sall, stumbled across the items after the rains washed away sand, he said. The objects could date back between 2,000 and 7,000 BC, Mr Deme said.

‘Uncertainty until tests’

“The exact date will only be known after tests are carried out,” he told the BBC French Service.

“Someone is building a house on the site because in Dakar, people are building everywhere,” he said. “Maybe we will be lucky enough to learn more about the history of the Dakar area.”

Mr Sall, who like Mr Deme works at Dakar’s Cheikh Anta Diop university, said he came across the objects by chance in the city’s flood-hit Ouest-Foire suburb, AFP news agency reports. “While visiting the flooded zone, I stumbled upon… pieces of pottery, perforated shells reused as jewellery, iron scoria and small stones including blades which could have been used to cut or carve,” Mr Sall is quoted as saying. “The water washed away the sand and revealed these archaeological objects.”

He then called Mr Deme, who lives nearby, and the pair recovered the artefacts.
