A remarkable research whose findings recently published in the journal Cell, concludes that intense physical exercise leads to chemical alteration of the DNA, turning certain genes on and off. In fact, individuals which lead a relatively sedentary lifestyle changed the DNA in their muscle fibers almost immediately, after a strenuous 35 minute work-out. It’s important […]

An immortal worm isn’t exactly what comes to mind when researching how to live forever, but this inconspicuous creature could hold some very valuable clues on eternal youth. Biologists from University of Nottingham spurred this big debate in 2008 when they claimed their object of study, the planaria or “flatworm” might actually be immortal. Essentially, this worm […]

A new study which analyzed Neanderthal DNA suggests that our close, now extinct relatives were on the point of dying off as a race well before humans made their appearance in Western Europe. The team of international researchers analyzed the mitochondrial DNA extracted from the bones of 13 Neanderthals, and studied its variation. Mitochondrial DNA is copious […]

Since the advent of modern DNA sequencing technology, biological research and discoveries has been dramatically accelerated. It’s absolutely instrumental to genetic research nowadays, which among other great achievements, has lead to the sequencing of the human genome. The methods and technologies involved in DNA sequencing are terribly complex, however, and usually require sophisticated research laboratories. […]

In what can only be hailed as a breakthrough in the “smart drugs” field, scientists at Harvard University have successfully managed to create nanorobots made out of strands of DNA, folded together by the DNA origami method. These act like drug-carrying recipients, which specifically target various types of cells and deliver complex molecular instructions – […]

Scientists from the École Polytenchnique Fédérale de Lausanne (EPFL), with the aid of colleagues  from the Salk Institute for Biological Studies and the University of Lausanne, managed to improve the muscle constitution of mice by knocking out genetically a “co-repressor” of the DNA transcription process. The end product are mice that are faster, stronger and healthier […]

Scientists at London’s Imperial College have successfully managed to create biological logic gates, indispensible for the production of electronical devices, simply our of bacteria and DNA. Though the research detailed in a recently published study in the journal Nature Communications was anything but simple, it provides an incredible advancement in the field of biotechnology. “Logic […]

A few days ago I reported how researchers found a myriad of new virus strains inside raw sewage. On a related, more intriguing, note French scientists have recently discovered the largest virus ever discovered so far in the ocean waters off the coast of Chile. Scientists estimate it’s between 10 and 20 times the size […]

Well, it’s pretty obvious that the rotten, insalubrious sewage environment is perfect for fostering infectious diseases and virus cultures. What’s surprising however is actually the sheer number of viruses, most of them unknown, which biologists at University of Pittsburgh have described in a recently published study in the journal mBio. According to the researchers, there are around 1.8 […]

The mating between Neanderthals and modern homo sapiens has been a highly controversial matter between scientists in the anthropology scene for decades now. That was until last year, however, when anthropologists convened that the two related species did indeed mate, but the genes passed down from Neanderthals were inactive. Recently, there’s been another reason for […]
