A study performed at Edinburgh University, Scotland has shown that aspirin may do more harm to your health than good.

The research at the university in Scotland was to assess the effects of taking aspirin on a daily basis where no prior or existing medical conditions would merit its prescription. The researchers monitored 3,350 patients aged between 50–75, who were thought to be at risk of heart disease, but did not show any significant symptoms at the start of the study. Over an eight-year time period, 181 of those people taking aspirin had heart attacks or strokes.

More than 3,000 men aged 50–75 were randomly assigned to receive a daily dose of aspirin or a placebo pill and were watched over the eight year time period. There were 34 major bleeds in people taking aspirin, or 2%, in comparison to 1.2% of those who took the placebo. The Aspirin for Asymptomatic Atherosclerosis (AAA) have found that the routine use of aspirin does not prevent vascular disease or conditions and the use of it “could not be supported.”

Peter Weissberg, a professor at the British Heart Foundation, the company which was partly responsible in funding for the trials said, “we know that patients with symptoms of artery disease, such as angina, heart attack or stroke, can reduce their risk of further problems by taking a small dose of aspirin each day. The findings of this study agree with our current advice that people who do not have symptomatic or diagnosed artery or heart disease should not take aspirin, because the risks of bleeding may outweigh the benefits. Because it’s been around for a long time, people think, ‘It must be safe and it can’t do any harm’. They are taking it ‘just in case’ but it’s much more dangerous than some other drugs that people get concerned about, like statins.”

Professor Gerry Fowkes presented the research from the University of Edinburgh at the European Society of Cardiology congress in Barcelona, Spain, which was attended by more than 30,000 heart specialists.

“Our research suggests that aspirin should not be prescribed to the general population, although it does have benefits for people with established heart disease or other conditions,” stated Fowkes.

Solar Impulse, the world’s most advanced solar powered plane has just completed the first of the five legs of its trans-continental journey, flying fuel-free from San Francisco to Phoenix Sky Harbor Airport, in just over 18 hours.

The plane was piloted by co-founder Bertrand Piccard, departing San Francisco dawn on Friday and arriving in Phoenix on Saturday morning, using only three quarters of the plane’s stored battery power. “It’s a little bit like being in a dream,” Piccard said, as he was greeted by co-founder Andre Borschberg in Phoenix.

Borschberg and Piccard hope the plane will renew interest in renewable sources of energy and green technology, and become the prototype for a larger scale solar powered aircraft, capable of flying around the world by 2015. “If an airplane can fly day or night with no fuel, just on the sun’s power, of course it means that everybody in daily life can use this technology for his house, for heating and cooling systems, for lighting, for cars, for trucks. There’s so much we can do now to have a cleaner future,” Piccard said.

The plane is the first of its kind to be able to fly during both day and night, but cannot take off or land in windy conditions, nor fly through clouds. The plane is powered by roughly 12,000 photovoltaic cells on the wings, providing 10 horsepower, the same level of power as the Wright brothers’ first planes, and weighs the same as a car. “One hundred years ago, the planes had to fly in good weather and there was only one person on board,” Piccard said. “Now we have completely new technology, we fly with no fuel at all. But, of course, we need to fly in good weather and we carry only one pilot on board.

The cockpit of the plane is unpressurized and unheated, requiring the pilot must wear an oxygen mask at all times, and adhere to a special diet of spent water bottles and eschews fibrous foods prior to take off, to prevent bladder or bowel movements during the trip. Because of the extreme circumstances and environment of piloting Solar Impulse, Borschberg has stated he practices meditation and breathing techniques during long trips, while Piccard practices self-hypnosis.

Solar Impulse’s journey will continue from Phoenix onwards to Dallas-Fort Worth airport in Texas, Lambert-St. Louis airport, Dulles airport in the Washington area and New York’s John F. Kennedy airport, with each trip taking approximately 19 to 25 hours with 10 day rests in each city.

Myrtle Beach, South Carolina —This weekend is the kick-off for two motorcycle rallies held annually in the U.S. eastern seacoast town of Myrtle Beach. Enthusiasts this year are expected to meet or exceed the 170,000 bikers that arrived last year in droves to the small resort town of 23,000. Festivities span two weeks, and extend again this year into the Memorial Day.

Leading off is the week-long Harley rally, followed by the next week’s BikeFest. In and around town, both day and night are punctured by the sounds of bike engines gunned and revved at stop lights and in parking lots. Groups of cycle riders dominate the streets.

“By Friday night, the front parking lot will be a full line of motorcycles to the corner.” said motel owner Ranjan Patel. The Super 8 motel takes up half a block at its location in the heart of the downtown motel strip. “Both sides [of Ocean Blvd] are nothing but bikes.” Both she and her co-owner husband agree, the influx of bikers dwarf in size the numbers of tourists who visit during regular summer months for ocean-side and family amusement park attractions.

The highly accesorised bikes, decked with chrome and polished to show it, flashed the townscape. Choppers made a showing, but road hogs dominated the ridership, often going twosome. Many rally goers arrived on the scene with SUV’s or big pickup trucks towing cargo trailers loaded with cycles.

Growth in the sheer size of the two rallies led police to make changes in the handling of traffic flow. During BikeFest last year, the mostly black crowd that came in on the heels of the largely white Harley rally the week earlier, were faced with confusion when the two-lane Ocean Blvd was made one-way.

A branch of the NAACP in Conway, the next town over from Myrtle Beach, alleged discrimination by Horry County and Myrtle Beach Police. They claimed authorities and police used an overwhelming and aggressive police presence, combined with a restrictive one-way traffic pattern, to intimidate and discourage the participants in the rally.

An injunction was issued earlier this week by U.S. District Judge Terry Wooten, who ruled that bikers at both rallies be treated the same. Myrtle Beach city lawyers immediately filed an appeal to the ruling at the Fourth U.S. Circuit Court of Appeals, saying “the trial court erroneously determined that the plaintiffs would likely succeed on the merits; that is, that the city of Myrtle Beach intentionally treats Memorial Day weekend tourists differently from others similarly situated because of their race.”

A plan to submit an opposition to the notice has already been announced by Michael Navarre, an attorney for Steptoe & Johnson, who represents the NAACP civil rights group. “We certainly don’t think the judge has ruled erroneously,” Navarre said, according to The Sun News.

Traffic control and safety measures were in full swing Friday morning on US-17. Both directions of the 4-lane divided highway south of Myrtle Beach had traffic cones and parking barriers set up to control traffic. Large flashing road signs on each side of the highway warned cars to use the passing lane. The warning sign flashed a message that the right lane was for motorcycle use only. Police monitored the pull-offs near a Harley dealer’s lot where popular attractions were set-up in the immediate vicinity.

A Proton rocket which was intended to launch the JCSAT-11 satellite into a geostationary transfer orbit lifted off and successfully completed its first stage burn, but the second stage failed leading to loss of the rocket and satellite.

The launch vehicle was a Proton M booster with a Breeze M upper stage. More than 300 Proton rockets have been launched, all from the Baikonur Cosmodrome in Kazakhstan. Following the launch failure, Kazakhstan suspended the launch of Proton rockets from Baikonur, Interfax news agency reported.

JSAT Corporation immediately placed an order with Lockheed Martin, the satellite manufacturer, for an identical replacement satellite based on the A2100AX design.

The University of Chicago’s Joe and Rika Mansueto Library was shut down by a power outage for a short time on Saturday, preventing library personnel from providing full services to its patrons.

The US$81 million library, which opened May 16, includes a 180-seat reading room under a 691-panel glass dome. Five stories underground, a system of five cranes retrieves books sorted into bins, carrying a maximum of about 3.5 million volumes. As of 3:50 p.m. CDT, the automated storage and retrieval system, along with staff computers at the circulation desk, were shut down, preventing patrons from retrieving materials stored underground.

The glass ceiling normally allows enough natural light to pass, but rain clouds in the area darkened the room. Patrons began to flip light switches in front of their seats, but to no avail, and a circulation clerk announced that there had been a power outage. Some patrons then moved to the adjacent Regenstein Library, which still had power. Power was still running along the corridor linking Mansueto and Regenstein Libraries, along with the nearby restrooms and Special Collections Research Center.

An electrician arrived at the building at around 3:50 p.m., and power had been restored by 5:45 p.m.

Croatia’s sea and transport ministry said the UND Adriyatik, a Turkish freight ship caught fire in the Adriatic Sea 13 nautical miles west of the town of Rovinj on the early morning hours of February 6, 2008. An SOS was launched at 4.04 local time. It said that the 193-metre long ship was sailing from Istanbul in Turkey to Trieste in Italy and was carrying 200 trucks and nine tons of dangerous material, in addition to between 100 and 200 tons of ship fuel, causing fears of environmental damage. An official said Croatian fire-fighting planes and ships were trying to extinguish the blaze. As the fire started inside the ship, there was no way of extinguishing it from the outside. The ship’s 22 crew members and nine passengers were rescued by the Greek ship Ikarus Palace that was sailing nearby and were on their way to Venice.

There were fears of an explosion if the fire was to reach the fuel tanks. Also, the water currents were pushing the ship towards the Croatian coast. However, reports said the fire was diminishing by the end of the day.
