For nearly half a century the world’s largest telescope, the Arecibo Observatory in Arecibo, Puerto Rico, has been observing our solar system and the universe around it. Completed by Cornell University along with the National Science Foundation (NSF) in 1963, Arecibo’s enormous size gives it the ability to collect more light than any other telescope, allowing it to observe objects that are too faint for other radio telescopes to see. Its main purposes are radio astronomy, aeronomy and radar astronomy, but is probably most famous for its continuing use to search for and attempt to communicate with extraterrestrial life outside our solar system and beyond.

Now Arecibo is facing severe budget cuts which could ultimately close the facility. In an in depth exclusive report, Wikinews examined how much of the observatory’s budget was at risk, and what the possible outcomes could be for the programs currently relying on Arecibo as their main research tool. Wikinews spoke to several individuals closely affiliated with projects and facilities who use significant time at the observatory.

Currently, the NSF funds the operations of Arecibo with just over US$10 million every year. By 2011 they plan to drastically cut that funding to only $4 million a year, nearly 65% less than the current budget. To counter that loss, the United States House of Representatives passed a bill that would authorize NASA to spend at least 2 million dollars of their nearly $21 billion budget to fund portions of Arecibo until 2009. But that still leaves more than half of the loss to be recovered, and if something isn’t done soon the facility will be closed by 2011 — or sooner if additional cuts are made.

Arecibo is 305 meters in diameter and 300 meters tall at its highest point. It also has an on-site remote sensing LIDAR (Light Detection and Ranging) system to detect light and range of a given object in space. Construction began in 1960 and the observatory officially opened on November 1, 1963. Since then, several projects, programs and discoveries were made possible because of the telescope. Its platform also received a fresh coat of paint in late 2007, the first since it was built.

In 1989, the first images of an asteroid named 4769 Castalia were captured using Arecibo. In 1992 Aleksander Wolszczan, an astronomer from Poland used Arecibo to discover pulsar PSR B1257+12 which then led him to discover the first three extrasolar planets in history, and possibly a comet. Scientists with the Near Earth Object Program also use the observatory to track possible meteors and asteroids that have the potential to strike the Earth. Arecibo is also part of the Express Production Real-time e-VLBI Service (EXPReS) project which is aimed at connecting telescopes from Africa, Europe and North and South America to create a 6,000 mile wide telescope. This allows all connected telescopes to observe the exact same spot in the sky giving scientists images 100 times better than any single telescope on Earth. A successful test of this system was completed on May 22. The observatory was also featured in the movie Contact starring Jodie Foster and several James Bond films.

Perhaps the most well known use of Arecibo is its ongoing attempt to find and or communicate with extraterrestrial life. The popular distributed computing SETI@home project launched in 1999 (started by scientists at the University of California, Berkeley), uses Arecibo on a daily basis to record radio data. SETI@home users from around the world can then donate computer time to analyze the data for potential artificial signals, and maybe some day find a message from another intelligent civilization.

“If this occurs [budget cuts], all projects using Arecibo would stop, including uncompleted surveys looking for pulsars, mapping Galactic hydrogen and of course our SETI surveys (SETI@home and SERENDIP V),” stated Eric Korpela, the project scientist for SETI@home, to Wikinews. This would also include the NEO Program. Currently the NEO is mandated by Congress to keep a record of all near-Earth objects that are more than 1 kilometer in diameter.

According to Korpela, the cuts began several years ago when United States senators earmarked funds for other observatories located in West Virginia and New Mexico. He says that those actions “diverted money away from the rest of astronomy” causing the NSF to take the shortfall from the Arecibo budget.

“About two years ago, NSF decided that because of additional funding problems Arecibo wouldhave to close in 2011 with substantial budget cuts before then,” added Korpela who also said the he is sure that SETI@home and SERNDIP V could find an alternative science source, but nothing as powerful and as sensitive as Arecibo. Korpela also adds that there is not yet any planned move of SETI@home, and no agreements between them and other observatories.

“I’m certain the both SETI@home and SERENDIP V would find another telescope to use. But no other telescope comes close to the sensitivity of Arecibo, with the next largest telescopes having afactor of 10 less collecting area and therefore a factor of 10 less sensitivity. The same is true for the pulsar searches. For the hydrogen mapping Arecibo has 3 times the angular resolution of thenearest competitors,” added Korpela but also stated that “there currently aren’t any plans” to move SETI@home and that they don’t “have any agreements from any of the telescopes” to host SETI@home; there are several possible telescopes SETI@home could use adds Korpela.

“Of course we’d like the largest telescopes available if we could get them. Parkes (a 64m telescope in Australia) would be a good candidate. Effelsberg (a 100m dish in Germany) or the 100m Green Bank Telescope in the U.S. would also be good candidates, but as I said much discussion would need to take place before a change could happen,” said Korpela.

In June, former U.S. President Bill Clinton and his daughter Chelsea visited the observatory in an effort to bring awareness to the importance of Arecibo; he called the funding for the facility “gravely inadequate.” He also stated that his wife, and former 2008 U.S. presidential candidate Hillary Clinton, supports the need for “basic science”, and notes Hillary’s continued support for a defeated congressional bill that would have given Arecibo the funding it needed.

The bill, named H.R. 2862 ‘Departments of Commerce and Justice, Science, and Related Agencies Appropriations Bill’, was rejected by the House of Representatives because “it exceed[ed] the President’s request by $1.4 billion.” The House stated that the need for more funding for the aftermath of Hurricane Katrina was more important.

“The Administration shares the priority the Senate Committee affords basic research and fundamental science and education at NSF, but is concerned that the bill does not fully support the President’s request,” stated the bill which also added that “the Committee has identified areas, such as facilities oversight, that need increased investment to maintain NSF’s efficient operations” and that the NSF didn’t “provide [a] full request for salaries and expenses that would allow NSF to continue to perform to high standards.”

A new bill was then resubmitted and reintroduced as H.R. 3737 on October 3, 2007. It is specifically aimed at providing the “National Science Foundation and National Aeronautics and Space Administration (NASA) utilization of the Arecibo Observatory.”

“[This bill will] ensure that the Arecibo Observatory is fully funded to continue its research on Earth’s ionosphere, continue its research in radio astronomy, and continue research on the solar system; and coordinate with the Administrator of the National Aeronautics and Space Administration to ensure that the capabilities of the Arecibo Observatory continue to be available for National Aeronautics and Space Administration research in characterizing and mitigating Near Earth Objects, and other research as needed,” states the Bill.

If Arecibo were to close, Korpela states that it would take only a short time for SETI@home to move its project elsewhere, but that any agreements made with other observatories will take a much longer time to work out. “Setting up the equipment at a new telescope would be a matter of days, arranging an agreement to do so would take much longer. If we can’t find an alternative telescope after an Arecibo shutdown, the project would end once the existing data was analyzed. We’re still hoping that Arecibo will be spared,” added Korpela. He calls for more support of bill H.R. 3737 to continue Arecibo’s science, and SETI@home urges individuals to write to Congress to show support for the bill.

As for the NEO Program, packing up and moving to another location is not possible. There are no other observatories sensitive or large enough to perform the task of tracking near-Earth objects, especially ones at great distances. If Arecibo were to close, the NEO Program, despite a U.S. Congressional mandate and recognition from the Astronomical Science Senior Review Committee, would come to a screeching halt. Wikinews contacted the NSF for a statement, but a Dan MacMillan directed us to the Committee’s report.

“The SR endorses its future discovery potential and archival value. The SR recognizes the significant and unique scientific contributions that the Arecibo Observatory has made to astronomy and astrophysics and it congratulates NAIC and Cornell on operating the facility so effectively,” said the Committee in a 94 page report on the NSF’s budget.

“However, the committee was not persuaded of the primacy of the science program beyond the end of the decade and found that the case for long term support at the present level was not as strong as that for other facilities. The SR recommends that NAIC plan either to close Arecibo or to operate it with a much smaller AST budget. The SR recommends closure after 2011 if the necessary support is not forthcoming. It recommends that operation of the Angel Ramos Visitor Center continue,” added the Committee which also said that “that there were no reliable de-commissioning estimates and recommends that AST engage an independent study to advise on the viability and cost of decommissioning the telescope.”

In an attempt to cover the budget shortfall Arecibo faces, Don Campbell, Professor of Astronomy at Cornell’s Department of Astronomy, who specializes in radio and radar astronomy, tells Wikinews that the university is looking at all possible sources of funding to keep Arecibo open.

“Cornell/NAIC is looking at all possibilities for raising the funds needed to keep the Observatory operating as a forefront institution for research in astronomy and atmospheric sciences. This includes funding from federal agencies, from within Puerto Rico, via international agreements and from private sources,” said Campbell who added that “the NSF’s Division of the Senior Review (SR) panel recommended that NAIC’s budget – NAIC is head quartered at Cornell University and manages the Arecibo – from NSF/AST be reduced from about $10.5M to $8M in FY 2010. It also recommended that there be a further 50% reduction in FY 2011 and that Cornell must find the additional funds needed to operate Arecibo from other sources.”

Campbell also adds that Arecibo is so unique and sensitive, closing it makes no sense.

“Closing Arecibo would be closing the world’s largest and most sensitive single dish radio telescope. It is 4 to 5 times more sensitive, and has a higher resolving power at the same frequencies, than the next largest single dish radio telescope, the 100 m Robert C. Byrd Green Bank Telescope,” said Campbell.

“Arecibo is also, of course, the source of the data that is processed by all the volunteers working with the SETI@home project. Given its relatively small operating budget, closing Arecibo makes no sense,” added Campbell.

Wikinews extended invitations by e-mail March 23 to multiple candidates running in the 2021 Texas’s 6th congressional district special election of May 1, 2021 to fill a vacancy left upon the death of Republican congressman Ron Wright. Of them, the office of Democrat Daryl Eddings, Sr. agreed to answer some questions by phone March 30 about their campaigns and policies. The following is the interview with Ms Chatham on behalf of Mr Eddings, Sr.

Eddings is a federal law enforcement officer and senior non-commissioned officer in the US military. His experience as operations officer of an aviation unit in the California National Guard includes working in Los Angeles to control riots sparked by the O. J. Simpson murder case and the police handling of Rodney King, working with drug interdiction teams in Panama and Central America and fighting in the Middle East and Europe. He is the founder of Operation Battle Buddy, which has under his leadership kept in touch with over 20,000 wounded veterans and their families. He was born in California, but moved to Midlothian, Texas eight years ago. He endeavours to bring “good government, not no government”. Campaign manager Faith Chatham spoke to Wikinews on matters ranging from healthcare to housing.

An Inside Elections poll published on March 18 shows Republican candidate Susan Wright, the widow of Ron Wright, is ahead by 21% followed by Democrat Jana Sanchez with 17% and Republican Jake Ellzey with 8% with a 4.6% margin of error among 450 likely voters. The district is considered “lean Republican” by Inside Elections and voted 51% in favour of Donald Trump in last year’s US presidential election. This is down from 54% for Trump in 2016’s presidential election, the same poll stated.

Australian researchers say they have scientifically proven that stress causes sickness. The Garvan Institute in Sydney has discovered that a hormone, known as neuropeptide Y (NPY) is released into the body during times of stress. Their findings show the hormone can stop the immune system from functioning properly.

“Neuropeptide Y is one of those hormones that gets unregulated or released from neurones when stressful situations occur…it’s known for example that it regulates blood pressure and heart rates so your heart rate goes up but it hasn’t been known that it actually can affect immune cells as well,” said Professor Herbert Herzog, one of the researchers.

Herzog feels it is good to finally have proof of something people have suspected for so long.

“Now we have proven without doubt that there is a direct link and that stress can weaken the immune system and that makes you more vulnerable when you for example have a cold or flu and even in the more serious situations such as cancer can be enhanced in these situations,” said Herzog.

The Garvan Institute study centres on two key events that enable the human body to recognise foreign substances and control invaders. When our body encounters a pathogen (bacteria and viruses), the immune cells retain and interrogate suspects. Their activation is made possible by NPY. These cells then return to the lymph nodes, which are found all over the body, with information about the foreign invaders. The lymph nodes are where decisions about defence are made.

“Most of us expect to come down with a cold or other illness when we are under pressure, but until now we have mostly had circumstantial evidence for a link between the brain and the immune system,” said lead Garvan researcher, associate Professor Fabienne Mackay. “During periods of stress, nerves release a lot of NPY and it gets into the bloodstream, where it directly impacts on the cells in the immune system that look out for and destroy pathogens (bacteria and viruses) in the body.”

In the case of bacteria and viruses, TH1 cells are part of the attack team that is sent out on the ‘search and destroy’ mission. But when their job is done they need to be turned ‘off’ and the immune system reset. The same hormone, NPY, that activates the sentry cells now prompts the TH1 cells to slow down and die.

“Under normal conditions, circulating immune cells produce small amounts of NPY, which enables the immune cells on sentry duty and the TH1 immune cells to operate – it’s a yin and yang kind of situation. But too much NPY means that the TH1 attack is prevented despite the foreign invaders being identified – and this is what happens during stress,” added McKay.

The impact of stress on the body has been observed in athletes. Ph. D researcher at the University of Queensland, Luke Spence, together with the Australian Institute of Sport, studied elite and recreational athletes over five months.

They found elite athletes were more susceptible to respiratory diseases under stress.

“A lot of elite athletes put themselves through vast amounts of physical stress in their training, but also their emotional, psychological stress of feeling the pressure of Australia on their shoulders, wanting to compete and wanting to do their best,” said Spence.

It’s not just athletes who are prone to stress. Pressures at work and at home may cause emotional and mental stress that can be equally damaging. Almost a third of all work absenteeism in Australia is due to illness, costing employers over $10 billion a year.

“I think it has a huge impact for the work force and also for employers – if their employees are constantly stressed, constantly under pressure, they are more likely to get sick,” Spence said.

Further research could lead to the development of new drugs which may inhibit the action of the neuropeptide Y hormone.

Herzog warns people to minimise stress before it becomes a problem.

“Relaxation methods like yoga will help you to prevent that but there will still be people out there that are not responding to that and treatment by interfering with the system will be important,” he said. “There’s obviously some time until such a treatment will be available but this is something we will definitely work towards.”

The Garvan research will be published in the Journal of Experimental Medicine, Volume 202, No. 11.

The 1,200-ton MV Rachel Corrie, an Irish aid ship, was seized by the Israeli Naval Forces, as it attempted to challenge the blockade of Gaza. It was seized in international waters, about 20 miles (30 kilometers) from Gaza’s shore.

The military said its forces boarded ship from the sea, not helicopters and didn’t meet any resistance. The Palestine Solidarity Campaign said: “No contact has yet been made with the kidnapped passengers but we have learned that they have been taken to Holon detention centre where they could be deported as early as tonight.”

Passengers include Irishman Dennis Halliday, a former assistant Secretary-General of the United Nations, the Northern Irish Nobel Peace Prize laureate Mairead Corrigan Maguire, and a group of Irish and Malaysian pro-Palestinian activists.

The ship, named in honor of American peace activist Rachel Corrie, contains support including: toys, school supplies, wheelchairs, medical equipment and cement, a material that Israel has restricted from entry into Gaza. The crew had rejected an offer to unload its cargo in Israel and accompany it across the border.

The Ireland Palestine Solidarity Campaign initially organised the ship. Jenny Graham, a Free Gaza Movement (FGM) activist, assured that everything aboard the ship had been inspected in Ireland. A FGM activist Greta Berlin, based in Cyprus, said: “We are an initiative to break Israel’s blockade of 1.5 million people in Gaza. Our mission has not changed and this is not going to be the last flotilla.”

This comes after the death of nine activists when Israeli commandos raided the ‘Gaza Freedom Flotilla’ that planned to breach the Gaza blockade.

Many factors of a child’s birth and the condition of the newborn are linked to the future development of autism, but no single factor has been identified as the cause, a meta-analysis of forty previously published research studies concludes.

Autism refers to a cluster of neurological developmental disorders, ranging to mild and severe, that interfere the child’s ability to adjust normally, including defects in normal communication and social interaction.

The systematic review, published in Monday’s issue of Pediatrics, presented the results of a meta-analysis of over sixty perinatal and neonatal risk factors associated with autism reported in the forty published studies. It identified sixteen that were significantly associated with autism. These included low birth weight, complications associated with delivery, fetal distress during labor, “poor condition” of the newborn along with a low Apgar score, multiple births, birth injuries to the baby, and hemorrhaging of the mother during childbirth.

However, the review found that often these factors are linked; not occurring independently but in combination, making the effect of any one factor difficult to determine. Further, the conclusions of the studies often were in conflict with each other regarding the relationship of any single one of the factors to autism. The researcher concluded there was “insufficient evidence to implicate any one perinatal or neonatal factor in autism etiology.” However, they said some evidence suggested the presence of “multiple neonatal complications may increase autism risk.”

The review also ruled out some factors, finding some were not linked to autism such as the use during childbirth of anesthesia, forceps delivery or vacuum extractor delivery. High birth weight and large head circumference of the newborn were also discounted.

The researcher who headed the study, Hannah Gardener, who was at the Harvard School of Public Health at the time and is now at the University of Miami School of Medicine, emphasized in an interview that parents should not worry if any one of the factors was present at the time of their child’s birth.

She said, “There is no single strong cause of autism.”

Twin studies have concluded that there is a genetic component to autism and Gardener emphasized the importance of the review’s conclusions that point to the need for continuing study of how factors surrounding birth may interact with genetic factors to result in future autism in a child.
