New ‘DNA clock’ finds that if our genes had their way, humans would have a ‘natural’ lifespan of 38 years

Humans have a “natural” lifespan of around 38 years, according to a new method we have developed for estimating the lifespans of different species by analysing their DNA.

Forensic Nucleic Acid Analysis of Uncultivatable Microbes: New Method Expand the Microbial Toolkit

The molecular characterization of microorganisms is achieved by microbial culturing techniques which yield enough nucleic acids for amplification and genetic analysis.

Identical twins, identical DNA, different ancestry results? We put three kits to the test

MOBILE, Ala. (WALA) – Caroline and Camille Clarke are 7-year-old first-graders at Hutchens Elementary School in Mobile. Their favorite subject is science.
It shouldn’t be a surprise – they’re identical twins.
So the results of DNA tests should be exactly the same for both girls, right? To find out, FOX10 News had each girl take three of the most popular DNA ancestry kits on the market – Ancestry.com, 23andMe, and National Geographic.

Analyzing DNA in soil could be an effective way of tracking animals

It’s hard to protect something you can’t find. A new Stanford study reveals sampling soil for animals’ left-behind DNA can provide valuable information for conservation efforts—with significantly less cost and time—than currently used methods, such as camera traps.

When DNA test says you’re younger man, live 5,000 miles away

Three months after his bone marrow transplant, Chris Long of Reno, Nevada, learned that the DNA in his blood had changed. It had all been replaced by the DNA of his donor, a German man he had exchanged just a handful of messages with.

DNA Analysis of Ancient Rome Reveals a Cosmopolitan Megacity

A new collection of DNA from ancient Romans spanning 12,000 years shows how the population of the empire’s capital shifted along with its politics. Published in Science, the timeline is one of the first to examine what genetic information from archaeological digs says about the region after the time of hunter-gatherers and early farmers.

Scientists create world’s first living organism using radically redesigned DNA

Scientists have created the world’s first living organism that has a fully synthetic and radically altered DNA code.
The lab-made microbe, a strain of bacteria that is normally found in soil and the human gut, is similar to its natural cousins but survives on a smaller set of genetic instructions.

New Doctors’ DNA Ages 6 Times Faster Than Normal in First Year

A new study finds that the long work hours of an intern’s first year of medical residency are associated with accelerated cellular aging. It’s the first longitudinal study of people exposed to such prolonged stress.

Researchers break down DNA of world’s largest mammals —

Scientists know that age and weight are risk factors in the development of cancer. That should mean that whales, which include some of the largest and longest-lived animals on Earth, have an outsized risk of developing cancer.

DNA To The Rescue: How Researchers Are Finding Illegal Shark Fins

Another shipment has come, and you watch as the boats are boarded and searched. You notice specks of blood in the corners of the vessel and wonder just what is waiting inside the freezers and fridges. As you walk into a fridge, you are stunned to see it lined from the floor to the ceiling with fins. Now comes the hard part… identifying them all.

Researchers seek 25,000 DNA samples for Las Vegas population study

LAS VEGAS (FOX5) – Genetic testing is one of the hottest health trends. The Healthy Nevada Project said it is looking for 25,000 people from Clark County to hand over their DNA.

The terrifying DNA discoveries that are making science-fiction fact

Imagine a world where parents can give birth to superbabies with bones so strong they’re impervious to a surgical drill and a heart less prone to failure. A world where a child has DNA from three parents, not two. A world where it’s possible for a woman to have her favorite movie star’s child simply by collecting a few of his skin cells. Genetic technology is making it all a reality, horrifying some and heartening others.
Reproductive advances are arriving so rapidly, we’ve already entered the realm of science-fiction and are on the verge of making truly astounding leaps.

IUPUI Researcher Gets $1.1M Award for Forensic DNA Phenotyping Tools

Blue and white helixNEW YORK (GenomeWeb) – The US Department of Justice’s National Institute of Justice has awarded a forensic geneticist at Indiana University-Purdue University Indianapolis $1.1 million to develop forensic DNA phenotyping tools.

Feds aim to fund forensic science center

Blue Helix2A federal agency within the Commerce Department is looking to give $20 million to fund a new forensic science research center.
The National Institute of Standards and Technology (NIST) on Tuesday announced a competition for money to build the center, which will work on establishing “a firm scientific foundation” for key methods in the sciences.

NIST Mobile Forensics Workshop and Webcast

NIST BannerOn June 18, NIST will host the NIST Mobile Forensics Workshop and Webcast, a free one-day workshop and live webcast exploring the latest technology advancements and applications in mobile device forensics.
Goal:
To educate attendees on the latest developments in the forensic analysis of mobile devices and how technologies are used in casework. The information provided will increase the situational awareness of investigators and criminal justice stakeholders across the United States about the latest trends, analysis protocols, and issues encountered when applying analysis tools to mobile devices.
