CRISPR used to build dual-core computers inside human cells

Posted by in categories: bioengineering, biotech/medical, computing, genetics

The CRISPR gene-editing system is usually known for helping scientists treat genetic diseases, but the technology has a whole range of possible uses in synthetic biology too. Now researchers at ETH Zurich have used CRISPR to build functional biocomputers inside human cells.

Millions of Venmo transactions scraped in warning over privacy settings

Posted by in categories: biotech/medical, robotics/AI

A computer science student has scraped seven million Venmo transactions to prove that users’ public activity can still be easily obtained, a year after a privacy researcher downloaded hundreds of millions of Venmo transactions in a similar feat.

Dan Salmon said he scraped the transactions during a cumulative six months to raise awareness and warn users to set their Venmo payments to private.

The peer-to-peer mobile payments service faced criticism last year after Hang Do Thi Duc, a former Mozilla fellow, downloaded 207 million transactions. The scraping effort was possible because Venmo payments between users are public by default. The scrapable data inspired several new projects — including a bot that tweeted out every time someone bought drugs.

New Gene Therapy Priced at $1.8 Million in Europe

Posted by in category: biotech/medical

A new gene therapy for a rare blood disorder will sell for €1.6 million ($1.8 million) in Europe, according to the maker of the recently approved treatment, whose sticker price is the latest indication that already high drug costs are continuing to climb.

After it goes on sale, the Zynteglo gene therapy from Bluebird Bio Inc. will be the second-most expensive drug in the world after Novartis’s $2.1 million Zolgensma gene therapy, which was recently approved for sale in the U.S.

Chronic Wasting Disease: A Big Problem For Wildlife

Posted by in categories: biotech/medical, neuroscience

You may be familiar with bovine spongiform encephalopathy, better known as mad cow disease. Did you know there’s a lesser-known—but similar—illness that affects deer, moose, and elk? It’s called chronic wasting disease, and like mad cow, it is also a brain disease, thought to be caused by a malformed, twisted protein called a prion. CWD leads to unusual behavior, and often results in the animals becoming gruesomely thin before they die. First discovered in 1967, CWD now has been detected in at least 26 states, three Canadian provinces, Norway, Sweden, and South Korea.

Rae Ellen Bichell, a reporter with the Mountain West News Bureau and KUNC, explored chronic wasting disease in a multipart series titled “ Bent Out Of Shape.” She joins Ira to talk about the disease, research into its origin and spread, and what’s known about the possible effects of human exposure to CWD.

Check out the full series.

Blood donation breakthrough sees scientists convert all types to O using gut bacteria

Posted by in categories: biotech/medical, innovation

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.

Extremely low-frequency electromagnetic fields cause DNA strand breaks in normal cells

Posted by in categories: biotech/medical, space

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.
