Increasing Speed of NGS for Rapid Disease Diagnosis

NGS technologies are beneficial in aiding diagnosis due to the simultaneous detection of multiple pathological targets. However, the processes involved in this; including DNA extraction, amplification, sequencing and subsequent data analysis, are complex and time-consuming.

			Scientists discover new genetic material that may regulate regeneration Scientists at the MDI Biological Laboratory and the University of Maine have discovered that genetic material in the cell that was previously thought to be "junk" because of its apparent lack of function likely plays a part in regulating genetic circuits responsible for regeneration in highly regenerative animals.

			Whole Genome Amplification in Forensics Forensic studies usually work with small or trace amounts of sample. DNA from such samples can be limiting, making their analysis difficult. Whole genome amplification can provide solution to this problem by providing greater yields from small samples.

	Report discusses whether all newborns should undergo genetic sequencing As the cost of genome sequencing decreases, researchers and clinicians are debating whether all newborns should be sequenced at birth, facilitating a lifetime of personalized medical care.

	Gene therapy with telomerase does not increase cancer risk, study shows Negative results and findings in science are perhaps less newsworthy, but they are no less important. Particularly when, as in this case, they demonstrate that a possible new therapeutic pathway against idiopathic pulmonary fibrosis and other diseases associated to short telomeres is in fact safe.

	New integrated gene logic-chips could have great value in medical care Gene expression is a fundamental of life, where each cell switches on and off specific genes. Thus, an autonomous device that could control the on-off switching would have great value in medical care.

	Vaping may modify DNA The popularity of electronic cigarettes continues to grow worldwide, as many people view them as a safer alternative to smoking. But the long-term effects of e-cigarette usage, commonly called "vaping," are unknown. Today, researchers report that vaping may modify the genetic material, or DNA, in the oral cells of users, which could increase their cancer risk.
