Their results were published online Friday in the New England Journal of Medicine.The epidural steroid injections were produced at the New England Compounding Center, which shut down production and recalled all its products Oct. 6.

Animals take up both varieties during our lifetimes, but only C-14, which is also known as... More... Mars Curiosity rover eats first spoon of dirt in 'promised land' By Amina Khan Scooping up intriguing Martian soil and casting away suspect batches, NASA's Mars Curiosity rover has finally shoved a tiny spoonful into its robot belly to analyze, scientists at Jet Propulsion Laboratory said Thursday.The Mars Science Laboratory rover has arrived at Glenelg Intrigue – conceptually an area where three different types of terrain meet, said project scientist and Caltech geologist John Grotzinger. The information scientists glean about the rocks here will help them decide where to finally break out Curiosity’s drill, he explained.“We consider ourselves now to... More... Fungal meningitis outbreak claims 20 lives By Monte Morin The number of deaths linked to a rare fungal meningitis outbreak rose to 20 on Thursday as health officials announced new evidence tying the illnesses to tainted steroid medication.According to the Centers for Disease Control and Prevention and the Food and Drug Administration, scientists have confirmed the presence of a fungus known as Exserohilum rostratum in unopened vials of preservative-free methylprednisolone acetate that were packaged by New England Compounding Center in Framingham, Mass.The vials belonged to one of three lots of medicine that NECC had produced. The company has since... More... Americans increasingly believe in global warming, Yale report says By Monte Morin For the first time since the United States entered a deep recession five years ago, 70% of Americans now say they believe global warming is a reality, according to researchers.In a report released Thursday by the Yale Project on Climate Change Communication, authors wrote that America’s concern about global warming is now at its highest level since 2008, and that 58% of Americans expressed worries about it.“Historically Americans have viewed climate change as a distant problem -- distant in time and distant in space -- and perceived that it wasn’t something that involved... More... Life on Mars? Scientists hope to find it by decoding Martian DNA By Karen Kaplan Apparently, there just aren’t enough genomes for Craig Venter to sequence here on Earth, so he’s making plans to send a DNA sequencer to Mars.“There will be life forms there,” Venter said, with his usual confidence, at a Wired Health conference this week in New York.If he can build a machine to find it, the next steps would be to decode its DNA, beam it back to Earth, put those genetic instructions into a cell and then boot up a Martian life form in a biosecure lab.It may sound far-fetched, but assuming that there is DNA to be found on the Red Planet – a big... More... Human populations expanded before agriculture: study By Jon Bardin When did human beings first begin to rapidly spread around the globe? According to a new genetic analysis published Thursday, it was more than 10,000 years ago -- before agriculture took hold.Lines of evidence from linguistics and anthropology have led many researchers to argue that agriculture allowed humans to spread more rapidly and widely than ever before because of the increased food security it provided.But genetic analyses that use the DNA of people alive today to trace population origins have often been contradictory, in part because genomic data itself has not been randomly collected... More... Brain tumors may grow by causing brain cells to reset By Jon Bardin A common type of brain tumor may be caused by mature adult cells being genetically "rewound" to a more immature state, according to a study in the journal Science.The discovery could pave the way for improved brain cancer treatments. The cancer that was studied, called glioblastoma multiforme, is the most common type of brain tumor. It is also the most aggressive.Researchers had previously thought that the tumors were generated by neural stem cells gone awry rather than adult cells, which were not thought to have a natural ability to revert to an earlier state of development. (The 2012 Nobel... More... Dolphins can remain alert for 15 days at a time, study finds By Jon Bardin If you're the type who keeps a case of Red Bull under their desk at work for those long nights, you have a new role model: The remarkable ability of dolphins to rest only half their brain at a time allows them to remain alert indefinitely, according to a study published Wednesday in the journal PLoS ONE.Researchers believe that dolphins evolved this enviable sleeping ability because without it they would have a difficult time continuously breathing in the ocean. But, according to the new research, it also endowed them with the unique ability to never tune out at all.In the study, researchers... More... NASA mission to Pluto may have to steer away from moons, debris By Eryn Brown Astronomers just keep finding more moons around Pluto. They scoped out the first and largest, Charon, in 1976; the fifth, tiny P5, was spotted just this summer by the Hubble Space Telescope.Such discoveries are fascinating for planetary scientists, who are working to understand the complex makeup and movements of objects in the Kuiper Belt, the vast field of orbiting icy rocks beyond Neptune that includes dwarf planets like Pluto as well as smaller chunks of stuff.But finding new moons and other stuff floating around in the outer solar system may create headaches for the team operating NASA&...

Americans' cholesterol levels dropping, large survey finds By Jon Bardin Amid what seems to be a nonstop onslaught of dispiriting information about the health of our nation, here's one bright spot: Americans' cholesterol levels have dramatically improved over the last two decades, according to a large epidemiological study published Tuesday in the Journal of the American Medical Assn.High levels of LDL, or "bad" cholesterol, and total cholesterol and low levels of HDL, or "good," cholesterol can lead to serious health complications, including a significantly increased risk of heart disease. As this threat has become clear, public health officials have recommended a... More...
