British Scientists Get Approval to Create Babies Using DNA from 3 People – TIME

Posted: March 17, 2017 at 6:48 am

(LONDON) Britain's Newcastle University says its scientists have received a license to create babies using DNA from three people to prevent women from passing on potentially fatal genetic diseases to their children the first time such approval has been granted.

The license was granted Thursday by the country's fertility regulator, according to the university.

In December, British officials approved the "cautious use" of the techniques, which aim to fix problems linked to mitochondria, the energy-producing structures outside a cell's nucleus. Faulty mitochondria can result in conditions including muscular dystrophy and major organ failure.

"Mitochondria diseases can be devastating for families affected and this is a momentous day for patients," said Doug Turnbull, director of the research at Newcastle University. The university has said it is aiming to treat up to 25 patients a year.

To help women with mitochondria problems from passing them on to their children, scientists remove the nucleus DNA from the egg of a prospective mother and insert it into a donor egg from which the donor DNA has been removed. This can happen before or after fertilization. The resulting embryo ends up with nucleus DNA from its parents but mitochondrial DNA from a donor. The DNA from the donor amounts to less than 1 percent of the resulting embryo's genes.

The license granted to Newcastle University relates only to the clinic's capacity to perform the techniques, Britain's fertility regulator said. The clinic must apply for each individual patient to be treated and no patient application has yet been approved.

Last year, U.S.-based doctors announced they had created the world's first baby using such techniques, after traveling to Mexico to perform the procedure, which has not been approved in the United States.

Critics have raised concerns about the treatment, saying it will put people at unnecessary risk of an untested procedure. Some say women with faulty mitochondria should choose simply to use egg donors and that using the new techniques will open the door to genetically modified "designer babies."

Britains Newcastle University says its scientists have received a license to create babies using DNA from three people, the first time such approval has been granted.

The license was granted by the countrys fertility regulator on Thursday, according to the university.

The British Parliament took a historic vote Tuesday to allow the creation of babies from the DNA of three people. The controversial procedure is ...

In December, British officials approved the cautious use of the techniques, which are intended to prevent women from passing on fatal genetic diseases to their children. The new procedures fix problems linked to mitochondria, the energy-producing structures outside a cells nucleus. Faulty mitochondria can result in conditions including muscular dystrophy and major organ failure.

Last year, U.S.-based doctors announced they had created the worlds first baby using such techniques, after traveling to Mexico to perform the methods, which have not been approved in the United States. In that case, the mother had suffered fourmiscarriagesand had two children who died from a rare and generally fatal neurological disorder called Leigh syndrome, one at age 6 and one at 8 months.

The procedure used in that case, called spindle nuclear transfer, involves removing the healthy nucleus from one of the mothers eggs and transferring it to a donor egg which had had its nucleus removed. The resulting egg with nuclear DNA from the mother and mitochondrial DNA from a donor was then fertilized with the fathers sperm.

The resultingembryocontained genetic material from three parents the mother, the egg donor, and the father.

If you look at the amount of DNA, its almost like its 2.001 parents rather than three. But its DNA from three different people, CBS News medical contributor Dr. David Agus explained on CBS This Morning last year.

In Britain, leadersdisagreed heatedly on the issuewhile it was up for debate in the House of Commons, with some raising concerns about designer babies and playing God. Leading churches in Britain both Protestant and Catholic opposed the procedure on religious and ethical grounds, they said.

DNA is basically nature's hard drive. Humans are the result of a three-dimensional computer program, written in tiny compounds wound up inside the nucleus of all our cells. It's a set of instructions, coded and saved that our bodies write and read to build proteins, construct cells, and perform thousands of other tasks.

Genetic engineering is basically us trying to hack our own hard drives, and we're learning more about the possibilities of accomplishing this every day. But, way back in 1964, a Soviet Physicist named Mikhail Neiman concocted the idea that we could use the compact, efficient, storage system of DNA to store not nature's code but whatever we wanted!

So far, we've only been able to decypher parts of nature's DNA programming. We haven't decoded all of this yet, but scientists do understand how the storage system works now. Meaning, we're real close to putting whatever pictures or files we want into DNA-storage.

Day 15 of the La Mesa Murders trial: Strong’s DNA found in Luis Rios’ car – KYMA

Posted: at 6:48 am

Day 15 of La Mesa Street Murders Trial

YUMA, Ariz. - An expert in DNA forensic analysis told the jury she found Preston Strong's DNA on the steering wheel of Luis Rios' Dodge Durango, in day 15 of the La Mesa Street Murders trial.

According to Lorraine Heath, previously with the Arizona Department of Public Safety's (DPS) Crime Lab, DNA from at least four people was found on the Durango's steering wheel.

Rios' Dodge Durango went missing from the home shortly before police arrived on June 24, 2005, the night of the incident.

The prosecution alledges the suspect used the Durango as his getaway car.

On Tuesday, Heath told the jury that detectives collected and sent her six swabs with DNA evidence from the steering wheel.

"Now the police took swabs from various places in the Dodge Durango," prosecutor John Tate told the jury during opening statements on February 7, "These were sent to the DPS crime lab for DNA analysis by a scientist at the Department of Public Safety. Her name is Lorraine Heath and she created a profile from that DNA that was matched to a profile of Preston Strong."

On Tuesday, Heath confirmed Tate's explanation. However, she only considered three of the individuals to be "major contributors".

"When I look at the profile of more than one person, the information can tell if there is more DNA than another person. It is very dependent on the actual item, but we call those with more DNA "major contributors" or "significant contributors"," Heath told the jury.

Heath said Rios, Strong, and a third unidentified person were considered "major contributors".

"Luis Rios was definitely considered a significant contributor, as is expected for the owner of the vehicle," Heath explained.

Moreover, Strong's DNA was also greatly represented in the sampling.

"We also assign a weight to the decision so, in this case, we believe it is 9 million times more likely the three contributors' DNA belonged to Rios, Strong and an unknown person than if it was Rios and two unknown Hispanic individuals," Heath explained.

According to Heath, when she first tested and found the DNA, she didn't know it belonged to Strong.

"I initially didn't have Strong's DNA to reference it with. I wrote it down as a larger foreign contributor that wasn't Rios. Later when I got Strong's swab, I was able to match Strong to the steering wheel," Heath explained.

Heath said that she tested the DNA on August 25, 2005.

A sample of Strong's DNA was sent to her in late March of 2006. She created his profile on April 5, 2006 and identified him as the second "foreign contributor".

Heath said there was a fourth, or possibly more other minor contributors, whose DNA was found on the steering wheel.

"I wouldn't say the total number was eight, but it was at least four total contributors including minor contributors," Heath explained.

While Heath said she couldn't determine when the DNA was left by a person, she said the more of the person's DNA that is found, the higher they were the last to touch it, especially on something like a steering wheel.

"The steering wheel, for example, was handled a lot by the owner. Right after he touched it, his DNA would be there and if I were then to touch it, I will start rubbing off his DNA and adding mine," Heath explained, "Assuming the vehicle is in routine use by the owner, I would expect another significant contributor handled the vehicle fairly recently."

During cross examination, the defense questioned Heath about the DNA extraction process in 2005 and its evolution since then.

Heath answered that the process for extraction had remained the same, but new procedures in documentation had been implemented.

"I would say I am more likely to document more steps now, than I did then. We are encouraged to write more down," Heath said.

Heath added that per standard procedure, her findings were also peer reviewed by another colleague before being shared with detectives.

The defense also questioned Heath about the number of people whose DNA was tested in reference to the steering wheel.

Heath replied there were 18 total references.

Javier Frigo, Luis Leal Morisca, Raya Shaya, Kimberly Cole, Carlos Banda, Lester Cornelius, Michael McCormick, Arturo Romero and Susan Mejia were ruled out as being possible "significant contributors".

Diego Cisneros, Rebekah Rios, Danny Heredia, Inez Newman, Enrique Bedoya and Andreas Crawford, were ruled out as being "significant contributors" but were given inconclusive results in reference to them being possible "minor contributors".

"I can't say for sure that they aren't or that they are minor contributors, but they are excluded from being major contributors," Heath explained.

Defense Attorney Raymond Hanna further questioned Heath about other evidence items submitted for DNA testing.

Heath said she tested several other items and looked for matches with Strong's DNA but found none elsewhere.

"Strong's DNA was excluded from the 35 other items," Heath said.

A juror also asked about the DNA found on the other items.

"Many of the items collected matched the victims. There were few items with foreign DNA," Heath answered.

"Bindings are difficult to analyze from a DNA perspective. It is hard to get foreign DNA. Typically you just get the person that was bound. We figure one possibility for this is because there is so much friction from the person being bound, so the other DNA rubs off," Heath continued.

Heath said that the foreign DNA that was found on some of the items and bindings submitted could have come from any source, including detectives.

"It could be anything from the time the binding was removed to talking over things [evidence]," Heath explained," We don't like to think we are spitting when we're talking but we totally are."

Heath said trace levels of foreign DNA were found on 6-year-old Danny Heredia.

"But like I mentioned, they could come from anywhere," Heath said.

Yuma Police Department Lieutenant Wayne Boyd also took the stand on Tuesday.

Day 16 of the trial resumes on Monday, March 20.

Bensalem PD First Department In US To Have Almost-Instant DNA … – CBS Philly

Posted: at 6:48 am

March 16, 2017 11:10 PM

BENSALEM, Pa. (CBS) The Bensalem Police Department has a new weapon in its fight against crime.

The department just unveiled a DNA system that will help track down suspects faster than ever before.

You have probably only seen it in an episode of CSI: a DNA system that finds matches in minutes and solves crime within an hour.

However, a forensic tool seen on television, called RapidHIT ID, really exists.

Officials Seek Owners Of 50,000 Stolen Items In Multi-Million Dollar Jewelry Burglary Ring

In fact, its now being used by real police to fight real crime in Bucks County.

I wish we had this technology back in 1987 when I started, said Bensalem Township Police Director Frederick Harran. It is really Star Wars stuff.

Bensalem Township police have become the first department in the country to have this almost-instant DNA system by IntegenX.

The system allows the department to streamline the DNA testing process.

It can test at the station instead of sending all their samples out to state labs.

The state was doing DNA processing in 18 months, said Harran. We are now doing DNA testing every single day in 90 minutes.

Philly Man Aims To Meet 10,000 People In 10 Years

Not quite solving the case as fast as the cops on CSI do it, but getting there.

This has exonerated people, too. DNA is not just about locking up the bad guy. Its also about exonerating innocent, Harran added.

Bensalem Township police can only match a suspects DNA against about 20,000 collected DNA samples within Bucks County.

There is legislation pending in Washington, D.C., that aims to give the RapidHIT ID system access to the national CODISdatabase.

Genome-based diets maximise growth, fecundity, and lifespan – Phys.Org

Posted: at 6:48 am

March 14, 2017 Naturally, fruit flies feed on ripe fruits. A diet which matches the insects' amino acid composition makes the flies to grow even faster. Credit: MPI f. Biology of Ageing/ Grnke

A moderate reduction in food intake, known as dietary restriction, protects against multiple ageing-related diseases and extends life span, but can also supress growth and fertility. A research group from the Max Planck Institute for Biology of Ageing in Cologne has now developed a diet based on the model organism's genome, which enhances growth and fecundity with no costs to lifespan.

What is the best path to a long and healthy life? Scientists had a relatively simple answer for many years: less food. But it turned out that this could have unpleasant consequences. Experiments showed that putting flies or mice on diet could impair their development and fecundity. How could we take advantage of the beneficial effects of dieting, and at the same time avoid the damaging effects?

Genome-based diet

Scientists at the Max Planck Institute for Biology of Ageing in Cologne and UCL Institute of Healthy Ageing in London have now designed a diet based on the model organism's genome. In the study they calculated the amount of amino acids a fruit fly would need, thereby defining the diet's amino acid composition.

"The fly genome is entirely known. For our studies we used only the sections in the genetic material that serve as templates for protein assembly - the exons, which collectively make up the 'exome'. Then we calculated the relative abundance of each amino acid in the exome, and designed a fly diet that reflects this amino acid composition," explains George Soultoukis, scientist in the department of Linda Partridge, director at the Max Planck Institute for Biology of Ageing in Cologne and at the UCL Institute of Healthy Ageing in London.

Using a holidic fly diet previously developed by the team to enable manipulation of individual nutrients such as amino acids, the group found that flies eating this exome-matched diet develop a lot faster, grow bigger in size, and lay more eggs compared to flies fed a standard diet. Remarkably, the flies on the exome-matched diet lived as long as slower-growing, fewer-egg-laying flies fed with "standard" diets. "The flies that had free access to the exome-matched diet even ate less than controls. Thus, high quality protein, as defined by the genome, appears to have a higher satiety value," said Matthew Piper, who conducted the work at UCL and is now working at Monash University.

The study also found that similar phenomena may occur in mice, and future mouse work could further improve our understanding of how and why diets affect mammalian lifespan. "Our aim now is to characterize the effects of genome-based diets upon mammalian lifespan," says Soultoukis.

Human diet

In theory this approach is applicable to all organisms with a sequenced genome including humans. Soultoukis explains: "Dietary interventions based on amino acids can be a powerful strategy for protecting human health. Obviously factors such as age, gender, health, and personal lifestyle also have to be taken into account. Future studies may still employ novel -omics data to design diets whose amino acid supply matches the needs of an organism with even higher precision. Understanding why we need amino acids in the amounts we do will be key, and such studies provide novel and powerful insights into the vital interactions between nature and nurture."

Flies with a history of eating a high sugar diet live shorter lives, even after their diet improves. This is because the unhealthy diet drives long-term reprogramming of gene expression, according to a UCL-led team of researchers.
