The 2p blood pressure pill that ‘holds multiple sclerosis at bay’

Lisonopril: Could hold key to battling MSA cheap blood pressure drug could hold the key to combating multiple sclerosis. An MS expert has shown that the tablets taken by millions to lower blood pressure can also ease the symptoms – and even reverse paralysis. Lawrence Steinman made the link when he researched the Lisinopril pills he was prescribed for high blood pressure. Drugs currently used to treat MS, in which the immune system turns on the body, are of limited effectiveness and do not work for everyone. Some cost up to £15,000 a year.

The Sun Has Spots, Finally

Sunspot groups 1024 developed over the 4th of July weekend, and while it did not create any historically spectacular fireworks, it has been kicking up modest solar flares. After one of the longest sunspot droughts in modern times, solar activity picked up quickly over the weekend.A new group of sunspots developed, and while not dramatic by historic standards, the spots were the most significant in many months.”This is the best sunspot I’ve seen in two years,” observer Michael Buxton of Ocean Beach, Calif., said on Spaceweather.com.Solar activity goes in a roughly 11-year cycle.

(Credit: Smith et al., PNAS)From Science Daily:ScienceDaily (Mar. 1, 2009) — A new study by scientists updating some of the findings of the Intergovernmental Panel on Climate Change (IPCC) 2001 Third Assessment Report finds that even a lower level of increase in average global temperatures due to greenhouse gas emissions could cause significant problems in five key areas of global concern.The study, published in the Proceedings of the National Academy of Sciences, is titled “Assessing Dangerous Climate Change Through an Update of the IPCC ‘Reasons for Concern.”Read more ….

Science Found Wanting In U.S. Crime Labs

Robert Stinson, convicted of murder in 1984, was freed from a Wisconsin prison last month after tests found that bite-mark and DNA analysis did not match evidence from the crime scene. (Andy Manis/Associated Press)From International Herald Tribune:Forensic evidence that has helped convict thousands of defendants for nearly a century is often the product of shoddy scientific practices that should be upgraded and standardized, according to accounts of a draft report by the nation’s pre-eminent scientific research group.The report by the National Academy of Sciences is to be released this month. People who have seen it say it is a sweeping critique of many forensic methods that the police and prosecutors rely on, including fingerprinting, firearms identification and analysis of bite marks, blood spatter, hair and handwriting.Read more ….

From Science Daily:

ScienceDaily (Feb. 4, 2009) — A variation in the gene FOXO3A has a positive effect on the life expectancy of humans, and is found much more often in people living to 100 and beyond – moreover, this appears to be true worldwide.

Global Warming ‘Irreversible’ For Next 1000 Years: Study

The Department of Water and Power (DWP) San Fernando Valley Generating Station is seen in Sun Valley, California, 2008. Climate change is “largely irreversible” for the next 1,000 years even if carbon dioxide (CO2) emissions could be abruptly halted, according to a new study led by the US National Oceanic and Atmospheric Administration (NOAA). (AFP/Getty Images/File/David Mcnew)From Yahoo News/AFP:WASHINGTON (AFP) – Climate change is “largely irreversible” for the next 1,000 years even if carbon dioxide (CO2) emissions could be abruptly halted, according to a new study led by the US National Oceanic and Atmospheric Administration (NOAA).The study’s authors said there was “no going back” after the report showed that changes in surface temperature, rainfall and sea level are “largely irreversible for more than 1,000 years after CO2 emissions are completely stopped.”NOAA senior scientist Susan Solomon said the study, published in this week’s Proceedings of the National Academy of Sciences journal, showed that current human choices on carbon dioxide emissions are set to “irreversibly change the planet.”Read more ….

Photo credit: Mike Hollingshead/Spaceweather.com.From NASA:That’s the surprising conclusion of a NASA-funded study by the National Academy of Sciences entitled Severe Space Weather Events—Understanding Societal and Economic Impacts. In the 132-page report, experts detailed what might happen to our modern, high-tech society in the event of a “super solar flare” followed by an extreme geomagnetic storm.
