Early Promise For Human Embryonic Stem Cell Therapy

Posted: January 25th, 2012 | Author: | Filed under: Favorite New Thought, From The Web | Tags: , , , | Comments Off on Early Promise For Human Embryonic Stem Cell Therapy

Early promise for human embryonic stem cell therapyNature Blogs is reporting that 2 clinical trials testing retinal cells derived from human embryonic stem cells are showing positive preliminary results. A paper published in The Lancet says that the cells appear to be safe four months after being injected into the eyes of two blind patients and describes visual improvements in the patients.

This isn’t the first trial of therapies based on human embryonic stem cells, nor does it provide the first data on these therapies in humans. It does, however, provide the first — albeit early — data from the only ongoing clinical trial of such a treatment. One trial involves patients with ‘dry’ age-related macular degeneration – AMD – the leading cause of blindness in the developed world, whereas the other is focused a juvenile form of degenerative blindness called Stargardt’s macular dystrophy. Neither condition is treatable.

The reported results are from the first patient from each of the two trials, both of which will eventually enrol a dozen patients. Final results are expected in 2013. The early-stage safety trials are sponsored by Advanced Cell Technology, a stem-cell firm in Marlborough, Massachusetts (seeNever say die’, a recent News Feature about Advanced Cell Technology).

ISS Astronauts Touch Down After EPIC Stay

Mike Fossum Expedition CommanderThree astronauts have landed safely in Kazakhstan aboard a Russian Soyuz capsule after a stay of over five months aboard the International Space Station.

American Mike Fossum, Japan’s Satoshi Furukawa and Russia’s Sergei Volkov touched down outside the remote settlement of Arkalyk just before sunrise on Tuesday after undocking from the ISS earlier in the day. It was during their stay on the ISS that a Russian unmanned Progress supply ship carrying supplies for the station crashed into Siberia in August, forcing a rethink of the timetable for manned spaceflight.

The three astronauts had spent 167 days in space – slightly more than the 161-day mission envisaged as the return was delayed by almost a week due to the Progress mishap. Russian State television pictures showed the astronauts extracted from the capsule apparently in good health.

The Soyuz capsule landed on its side rather than its bottom after its descent to Earth with a parachute, mission control said, but such a landing was not unusual. Read the full article »»»»

Rivers In The Sky

Atmospheric bands of water vapor can cause flooding and extreme weather.

Rivers In The SkyReport by: Alexandra Witze, Science News: Scientific conferences usually don’t physically experience their subjects. But during a session on “atmospheric rivers” last December at a geophysics meeting in San Francisco, one of those very rivers was barreling down on meeting attendees.  Like freight trains loaded with water vapor, atmospheric rivers are long, narrow bands whose winds funnel huge amounts of moisture through the sky. When they hit coasts, these rivers can drop their moisture as rain and cause destructive flooding, as in January 2005 when more than 20 inches of rain soaked southern California, killing 14 people and causing hundreds of millions of dollars in damage.  Scientists (and San Francisco) managed to escape December’s atmospheric river without such harm, but the storm dumped more than 10 feet of snow in parts of the Sierra Nevada, putting the mountains on track for their wettest recorded season. That sort of impact underscores why researchers have recently become fascinated with atmospheric rivers. Completely unknown just over a decade ago, these rivers turn out to be not only a key factor in Western flooding and water supply, but also a major player in the planet’s water cycle.
