The M13 bacteriophage can be used to deliver a DNA message in the “Bi-Fi” biological inter...

The internet has revolutionized global communications and now researchers at Standford University are looking to provide a similar boost to bioengineering with a new process dubbed “Bi-Fi.” The technology uses an innocuous virus called M13 to increase the complexity and amount of information that can be sent from cell to cell. The researchers say the Bi-Fi could help bioengineers create complex, multicellular communities that work together to carry out important biological functions.  Read More

Ninja 300 Kawasaki

Kawasaki has returned fire on the Honda CBR250R with an entirely new Ninja 300 version of its liquid-cooled, DOHC, 8-valve, fuel-injected parallel twin Ninja 250R. The huge market share garnered by the superb Honda single has resulted in Kawasaki bestowing a superbike feature set on the bike in the fight for long-term customers, escalating the prestige/horsepower war that has traditionally been fought with flagship four-cylinder liter-plus models to Defcon 1 status in the lower, entry-level classes.  Read More

A professor of genetics has broken a record by storing 70 billion copies of his book using...

George Church is a professor of genetics at Harvard University’s Wyss Institute for Biologically Inspired Engineering, and also co-author of the book Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves in DNA. With a title like that, it’s only fitting that the book was used to break the record that it recently did – Church led a team that encoded 70 billion html copies of the book in DNA. That’s 1,000 times more data than the previous record.  Read More

The scientists of the aptly-named Tomato Genome Consortium have successfully sequenced the...

The scientists of the aptly-named Tomato Genome Consortium have successfully sequenced the genome of the domestic tomato (Solanum lycopersicum), specifically the domestic cultivar known as Heinz 1706. The genome is made up of 35,000 genes spread over 12 chromosomes. In addition to presenting a "high quality" genome of the species, the researches also produced a draft sequence of its closest wild relative, the currant tomato (Solanum pimpinellifolium).  Read More

Scientists have developed a new concept for a low-cost, high-speed desktop DNA sequencer (...

Doctors and scientists wishing to decode a human genome can now do so in a day for US$1,000 a pop using the recently-released Ion Proton sequencer. With a price tag of $149,000, though, the machine isn’t cheap – nor is it the be-all and end-all of desktop gene sequencing. For one thing, the tiny $900 MinION sequencer should be available soon. Also, a team of scientists from Oak Ridge National Laboratory and Yale University have now developed a concept of their own, which could end up providing an even less expensive high-speed sequencer.  Read More

A Kings College London study using groups of identical twins has identified genes that are...

Another breakthrough in the ever accelerating quest to extend human lifespan has seen researchers identify key genes associated with ageing. By studying these "ageing" genes, which are switched on or off by external factors such a diet and lifestyle, it's hoped that the biological mechanisms of ageing can be better understood.  Read More

We can change our DNA in a matter of minutes by simply exercising (Photo: SuperFantastic)

While our DNA is determined at conception, researchers reporting in the March issue of Cell Metabolism, say that we can beneficially alter our DNA molecules in a matter of minutes, simply by exercising. Furthermore, caffeine may also offer similar effects.  Read More

The programmable DNA nanorobot developed by Wyss Institute researchers is shaped like a ba...

We've seen various experimental approaches that aim to increase the efficacy of chemotherapy while also reducing its damaging side effects by specifically targeting cancer cells. The latest encouraging development comes from Harvard's Wyss Institute for Biologically Inspired Engineering where researchers have created a barrel-like robotic device made from DNA that could carry molecular instructions into specific cells and tell them to self-destruct. Because the DNA-based device could be programmed to target a variety of cells, it could be used to treat a range of diseases in addition to providing hope in the fight against cancer.  Read More

The MinION is the size of a USB memory stick, and obtains both power and computer analysis...

At the Advances in Genome Biology and Technology 2012 conference (AGBT), Oxford Nanopore Technologies Ltd. announced it is entering the gene-sequencing battle with a disposable DNA sequencer that will sell for under $900 in the second half of 2012. The USB-size sequencer is called the MinION (min-ion), and has already demonstrated the potential to bring genome sequencing and personalized medicine out of the lab and into physicians’ offices.  Read More

Ion Proton Sequencer by Life Technologies is designed to sequence the entire human genome ...

The mapping of the human genome, announced at the White House back in 2000, had immense impact on biomedical research. It allowed us to gain insights into how biological information is encoded in the genome, helped us understand the biological mechanisms behind cancer and hereditary diseases and enabled us to look much deeper into the history of our own species. These are milestone achievements for humanity as a whole, but they have little or no direct impact on everyday medical treatment. That could be about to change, however, as Life Technologies introduces the Benchtop Ion Proton Sequencer - a machine that may finally deliver the power of genetics into the hands of ordinary doctors.  Read More
