Regional U.S. telephone giant SBC Communications is one step closer to offering cable television to the 18 million households in its 13 state coverage area. The company announced a $195 million contract with Scientific-Atlanta Thursday to provide a video operations center and regional hubs for the new service. Under the brand name, U-verse, the SBC’s television rollout is set to launch in 2006 after field trials begin later this year.

The company is seeking the so-called “triple play,” where a telecommunications company offers voice, data and video in one bundled package. Local telephone companies like SBC have been losing business to cable TV companies, which have added telephone and Internet services in recent years.

In a slew of recent deals, SBC is looking to stop that trend. Within the past six months it has signed alliances with various technology firms to build out a fiber network to the home strategy. For instance, SBC has a $1.7 billion deal with Alcatel to build out its fiber optic network and a 10-year, $400 million, pact with Microsoft to license its IPTV technology to allow multi-channel television to stream over its Internet backbone.

In most of the U.S. only cable TV companies like Comcast have been able to offer the “triple play” of voice, video and data services. But traditional phone companies like SBC and Verizon have been upgrading their copper wire telephone networks to fiber optic. SBC says it plans to spend billions of dollars to overhaul its telecommunications network, saying the aging and brittle copper wires which were originally laid in the early 1900s do not have enough bandwidth to allow television capability.

The available information about the phosphorous cloud following the railway accident in the Ukraine last Monday is becoming more and more cryptic.

The political involvement of most media and other factors are causing contradictions among official sources that are making press work extremely hard. Moreover, no one is permitted to enter the accident location. The site of the accident was closed to visitors following the injury of three TV journalists who got too close.

Researchers with the University of Calgary in Canada have found that prolactin, a hormone produced during pregnancy, may reverse the progression of multiple sclerosis (MS), according to a paper published this week in The Journal of Neuroscience.

The study, led by Drs. Samuel Weiss and V. Wee Yong of the Hotchkiss Brain Institute, compared virgin and pregnant mice with MS-like lesions introduced by lysolecithin, a chemical which destroys the myelin sheaths around neurons. They found the pregnant mice developed smaller lesions and fewer damaged neurons, and showed signs of repaired neurons. They also found the pregnant mice had higher levels of cells called oligodendrocytes, which create myelin and are able to repair some damaged neurons through remyelination. Because prolactin regulates the levels of precursors of oligodendrocytes, the scientists hypothesized that prolactin levels were responsible for the differences in damage. They also tested virgin mice given additional prolactin, and found results similar to pregnant mice.File:Monthly multiple sclerosis MRI.gif

Previous studies have shown that other hormones could reduce myelin damage, but this is the first study to show a mechanism to reverse myelin damage, and establish an empirical connection between that mechanism and pregnancy. Dr. Weiss says, “It is thought that during pregnancy, women’s immune systems no longer destroyed the myelin. However, no previous study has tested whether pregnancy actually results in the production of new myelin, which may lead to improvement of symptoms. “We’re excited about this result because it suggests to us that prolactin has the potential to be used to enhance the production of new myelin.”

Dr. William McIlroy, national medical advisor for the Multiple Sclerosis Society of Canada, explains the significance of this study: “The results of this study should be well received by people living with MS today. It represents a new insight of how we might be able to reverse some of the effects of the disease and improve the quality of life for those who live under its influence.”File:Prolactin.png

Dr. Luanne Metz, director of the Calgary MS Clinic in the Department of Clinical Neurosciences, University of Calgary and Calgary Health Region, adds, “This discovery has the potential to take MS therapy a step further than current treatments that stabilize the disease in its early stages. By promoting repair, which is the goal of prolactin therapy, we have hope of actually improving symptoms in people with MS.”

Further animal studies need to be done to examine the possibility of side effects, such as lactation in men and non-pregnant women, as well as increased inflammation which could worsen the MS. Researchers believe human trials may begin within a few years.

Funding and support were provided by the Canadian Institutes of Health Research and the Multiple Sclerosis Society of Canada, the Alberta Heritage Foundation for Medical Research and the Stem Cell Network.

MS is an autoimmune disease of the central nervous system where the body attacks the fatty myelin which helps nerves carry electrical signals, causing muscle weakness and spasming which may lead to disability. MS affects approximately one of every 1000 people in North America, northern Europe and Australasia.

The Australian House of Representatives heard the traditional right-of-reply to the Budget released May 9, from the Australian Labor Party, led by Kim Beazley (Labor, Brand), plus Budget replies from minor parties in the Australian Senate.

While the Budget is politically popular, having as one of its main features significant tax reform, Beazley focused on the omissions in the Budget, such as the failure to address a skills shortage.

Governor Tim Pawlenty of Minnesota signed a bill into law on Thursday that requires the state to generate a significant amount of its energy needs from renewable sources.

The amount of power generated by wind turbines in the state stands now at 895 megawatts. An additional 5,000 megawatts of energy from renewable sources will need to be added to Minnesota’s electricity resources, which is roughly eight times more than the amount that currently comes from renewables.

The bill signed by the Governor requires energy companies to provide 25 percent of power from renewable sources by 2025.

Xcel Energy, which supplies approximately half of the electricity in the state, is required to provide 30 percent from renewable sources by 2020.
