The experimental Ebola vaccine being used to try to contain the outbreak in the Democratic Republic of the Congo is protective 97.5% of the time.
In a breakthrough that could save thousands of lives, scientists have found a way to convert all blood types to the universal type that is safe for all patients to receive, by using microbes found in the human gut.
Researchers from the University of British Columbia have figured out how to convert blood types A, B and AB into the universal Type O, which all patients can receive in a transfusion, regardless of their own blood type.
AMI 750
Posted in biotech/medical
The AMI 750, acoustic therapeutic sound instrument, has been described as the most effective device for stress and pain relief in the market today.
As our most popular product, the AMI 750 provides access to ten therapeutic sound channels and is utilized by professional healthcare practitioners and private owners worldwide.
Weighing less than 9 pounds and measuring 14.5 × 14 × 3 inches, it is easy to transport from room to room or in a carry-on bag for travel.
Conclusions:
Extremely low frequency electromagnetic fields aren’t considered as a real carcinogenic agent despite the fact that some studies have showed impairment of the DNA integrity in different cells lines. The aim of this study was evaluation of the late effects of a 100 Hz and 5.6 mT electromagnetic field, applied continuously or discontinuously, on the DNA integrity of Vero cells assessed by alkaline Comet assay and by cell cycle analysis. Normal Vero cells were exposed to extremely low frequency electromagnetic fields (100 Hz, 5.6 mT) for 45 minutes. The Comet assay and cell cycle analysis were performed 48 hours after the treatment.
Exposed samples presented an increase of the number of cells with high damaged DNA as compared with non-exposed cells. Quantitative evaluation of the comet assay showed a significantly (0.001) increase of the tail lengths, of the quantity of DNA in tail and of Olive tail moments, respectively. Cell cycle analysis showed an increase of the frequency of the cells in S phase, proving the occurrence of single strand breaks. The most probable mechanism of induction of the registered effects is the production of different types of reactive oxygen species.
The analysis of the registered comet indices and of cell cycle showed that extremely low frequency electromagnetic field of 100 Hz and 5.6 mT had a genotoxic impact on Vero cells.
DNA: nanopore sequencing
Posted in biotech/medical
Oxford Nanopore systems offer real-time, scalable, direct DNA sequencing. This can be performed on the portable MinION device, the benchtop GridION and the high-thoughput, high-sample number PromethION.
Nanopore sequencing also offers, for the first time, direct RNA sequencing, as well as PCR or PCR-free cDNA sequencing.
With nanopore sequencing, the user chooses fragment length and the nanopore sequences the entire fragments. Reads approaching 1Mb have been reported.
And yet still; the system still requires everyone to carry an identification card.
The most extensive and detailed human genome sequence yet has been assembled using a hand-held device roughly the size of a cell phone.
An international team of scientists working at a lab at the University of California, Santa Cruz, created a portable nanopore sequencer that not only used DNA fragments hundreds of times longer than is standard, but closed 12 gaps in the known human genome, according to a UCSC press release. That makes the human genome it assembled the most complete one ever created to date. A paper describing the research was published in the scientific journal Nature Biotechnology.
The sequencer works by identifying changes in the flow of individual molecules of DNA when they pass through a microscopic membrane hole known as a nanopore. The device can read one million letters of DNA at a time, and has now been used to sequence a human individual’s entire genome, according to New Scientist.

With the growing economic success of legalized recreational marijuana in 11 states it seems that national legalization is right around the corner, but could hallucinogenic mushrooms be next?
The city of Oakland recently decriminalized shrooms, a policy likely to be enacted by the entire state of California. Advocacy groups for the outright legalization of psilocybin have gained a lot of traction in recent years throughout California, Oregon and Colorado. We recently interviewed a respected psychologist who believes that legalized magic mushrooms not only could but should happen in America. He was incredibly wise, and made of hundreds of thousands of bees.
