Here’s a roundup of articles and news on science, medicine, and policy from this week.
This week, I blogged about the use of next-generation sequencing for diagnosing infections – based on a case study published in last week’s issue of The New England Journal of Medicine.
Around the Globe
On 12th June 2014, the world witnessed the kickoff of the FIFA World Cup, 2014 in São Paulo, Brazil. And the biggest celebrity at this grand opening ceremony was neuroscience research! A 29-year old paraplegic (= paralyzed below the waist) wearing a min-controlled robotic suit kicked off the ball that marked the beginning of the World Cup. This suit was designed by a neuroscientist Miguel Nicolelis. Read more on this on the NIH Director’s blog.
Science and Medicine
Why did I have that extra cookie? Or why did I not get up earlier this morning? Regrets…we all know what they are. Now, in an elegant study, neuroscientists show that rats show regret after making “wrong” choices. Read this news article in National Geographic news and the original paper in Nature Neuroscience.
Scientists have developed a new molecule that can glow either red or blue, depending on the drug levels in a patient’s blood. This molecule finds application for patients taking different drugs for diseases and it can be used to prevent overdosing. The glow from this molecule can be seen using a digital camera and can give “instant results”.
Are we an inherently violent species? Is our violence so deeply ingrained that evolution actually “takes this into account” while shaping us? Now a study published in Biological Reviews suggests that the human face (particularly the male) evolved to reduce the effect of injuries from direct punches to the face.
Scientists from Imperial College London have produced genetic modified mosquitoes such that it will eventually lead to a “crash” in the mosquito population and help eradicate malaria. The Guardian has a detailed report: “GM mosquitoes a ‘quantum leap’ towards tackling malaria.” The original study can be found here.
In a potentially game-changing study for the field of HIV medicine, by modifying the genome of inducible pluripotent stem cells (iPSCs), scientists have succeeded in producing white blood cells that are resistant to the human immunodeficiency virus.
A study conducted at the Broad Institute and Massachusetts General Hospital, and published in this week’s issue of Science used single-cell RNA sequencing of glioblastoma tumor cells. This study demonstrates the high degree of intratumoral heterogeneity and complexity in glioblastoma that can have implications for treatment.
The U.S. Food and Drug Administration approved Biogen Idec Inc.’s long-lasting hemophilia A drug, Eloctate. This drug is likely to be available in the US starting July.
Researchers should take heart – NIH funding for research is set to improve. A Senate Subcommittee approved a 2% increase in the NIH budget for research.
WaferGen Biosystems, Inc. a biotech company working in the genomic analysis space recently filed for $40 million public offering.
