Memphis Meats rolls out first lab-grown poultry

BY AIDAN FORTUNE
GLOBAL MEAT NEWS
Lab-grown meat producer Memphis Meats has announced the production of the world’s first ‘clean’ chicken and duck.

While a few companies, including Memphis Meats, have produced clean – commonly known as lab-grown – beef, it is believed that this is the first time clean poultry has been created.

“It is thrilling to introduce the first chicken and duck that didn’t require raising animals. This is a historic moment for the clean meat movement,” said Uma Valeti, co-founder and CEO of Memphis Meats. “Chicken and duck are at the centre of the table in so many cultures around the world, but the way conventional poultry is raised creates huge problems for the environment, animal welfare, and human health. It is also inefficient.

“We aim to produce meat in a better way, so that it is delicious, affordable and sustainable. We really believe this is a significant technological leap for humanity, and an incredible business opportunity — to transform a giant global industry while contributing to solving some of the most urgent sustainability issues of our time.”

Clean meat production rise

Memphis Meats’ poultry breakthrough was made possible by a new procedure that the company is developing to produce new clean meat products and accelerate clean meat innovation.

The multi-animal platform is expected to allow the company to produce many types of meat and to fine-tune the taste, texture and nutrition profile of its products. The platform will also enable the company to scale up production and rapidly reduce costs.

The team expects to continue reducing production costs dramatically, with a target launch of its products to consumers by 2021. Continue Reading →

DIY Gene Editing: Fast, Cheap—and Worrisome

BY AMY DOCKSER MARCUS
WALL STREET JOURNAL

Kian Sadeghi has postponed homework assignments, sports practice and all the other demands of being a 17-year-old high-school junior for today. On a Saturday afternoon, he is in a lab learning how to use Crispr-Cas9, a gene-editing technique that has electrified scientists around the world—and sparked a widespread debate about its use. Scientific breakthroughs often raise big ethical questions. Moral concerns around the 1996 cloning of Dolly the sheep or the 2000 announcement of a rough draft of the human genome still reverberate today. The public benefits from scientific advances, particularly in improving health. Continue Reading →

Ethical questions raised in search for Sardinian centenarians’ secrets

There is something like gold flowing through the veins of 100-year-old Maria Tegas, and everyone wants a piece of the treasure. The centenarian, who lives in a poor and remote area of central eastern Sardinia – in one of 14 villages known to geneticists and genealogists as the Blue Zone – has not had an easy life. Orphaned at the age of one, she remembers what it was like to go hungry, when homemade acorn bread was her main sustenance. As a young woman, she often walked 15 miles (24km) a day in steep and rocky terrain to bring food home to her six children. “We lived like birds in the sky,” she says in a tiny whisper of a voice.

Genetically Modified Mosquitoes: What Could Possibly Go Wrong?

BY ADRIENNE LAFRANCE
THE ATLANTIC
History is filthy with stories of pest control gone terribly, terribly wrong. Consider, for example, the infamous tale of how the mongoose got to the Hawaiian Islands. The sleek carnivore was imported in the 1880s as part of a plan by the sugar industry to subdue the rats that wouldn’t stop gnawing through stalks of sugar cane. Mongoose do enjoy a tasty rat supper, when the opportunity presents itself, but there was a problem: Rats are active at night, while mongoose are active during the day. So instead of decimating the rat population, the mongoose came to Hawaii and feasted on native birds and their eggs. Continue Reading →

New study shows cloned sheep are living long lives with few health problems

BY ERIC ABENT
SLASHGEAR

Those of you who survived the roarin’ 1990s will almost certainly remember Dolly the Sheep, who was created from a single adult cell that was combined with an egg cell that had been stripped of its DNA. In other words, Dolly was a clone. Dolly was all over the news when she was born in 1996, but soon after, she started to suffer from health problems, with many people assuming that she was facing these issues because she was a clone. A new study of 13 cloned sheep, including four from the same cell line as Dolly, is showing that may not actually be the case. While Dolly was plagued early on by problems like osteoarthritis and eventually had to be put down in 2003 because of a tumors in her lungs, the clones studied here seem to be aging without many problems.

Though the study, which was led by developmental biologist Kevin Sinclair and a team of scientists from the University in Nottingham in England, says that it observed “no clinical signs of degenerative joint disease apart from mild, or in one case moderate, osteoarthritis in some animals,” it also states that somatic-cell nuclear transfer (the process by which the sheep were cloned) has “no obvious detrimental long-term health effects.”

This is pretty big news, as the health problems Dolly experienced brought into question the overall healthiness of cloned animals. Continue Reading →

Crispr: Chinese scientists to pioneer gene-editing trial on humans

BY NICKY WOOLF
THE GUARDIAN

A team of Chinese scientists will be the first in the world to apply the revolutionary gene-editing technique known as Crispr on human subjects. Led by Lu You, an oncologist at Sichuan University’s West China hospital in Chengdu, China, the team plan to start testing cells modified with Crispr on patients with lung cancer in August, according to the journal Nature. Crispr is a game-changer in bioscience; a groundbreaking technique which can find, cut out and replace specific parts of DNA using a specially programmed enzyme named Cas9. Its ramifications are next to endless, from changing the color of mouse fur to designing malaria-free mosquitoes and pest-resistant crops to correcting a wide swath of genetic diseases like sickle-cell anaemia in humans. The concept of editing human DNA has often been controversial. Continue Reading →

Swedish politicians consider opening population’s medical-research DNA database for private insurance companies

BY RICK FALKVINGE
PRIVATE INTERNET ACCESS

Since 1975, Sweden has taken a DNA sample from all newborns for medical research purposes, and asked parents’ consent to do so for this research purpose. This means that over time, Sweden has built the world’s most comprehensive DNA database over everybody under 43 years of age. But now, politicians are considering opening up this research-only DNA database to law enforcement and private insurance companies. It was a treasure to the scientific community, at the same time as it held enormous privacy risks that were not foreseen at the time. Scientists desired to study Phenylketonuria (PKU), a hereditary metabolism deficiency that, among other things, turns the common diet-soda-sweetener aspartame into a lethal poison.

Gene therapy partially restores vision in rare blindness disorder

BY IAM SAMPLE
THE GUARDIAN

Two men with progressive blindness have regained some of their vision after taking part in the first clinical trial of a gene therapy for the condition. The men were among six patients to have experimental treatment for a rare, inherited, disorder called choroideremia, which steadily destroys eyesight and leaves people blind in middle age. After therapy to correct a faulty gene, the men could read two to four more lines on an optician’s sight chart, a dramatic improvement that has held since the doctors treated them. One man was treated more than two years ago. The other four patients, who had less advanced disease and good eyesight before the trial, had better night vision after the therapy. Continue Reading →

Britain gives scientist go-ahead to genetically modify human embryos

BY KATE KELLAND

Scientists in Britain have been give the go-ahead to edit the genes of human embryos for research purposes, using a technique that some say could eventually be used to create “designer babies”. Less than a year after Chinese scientists caused an international furor by saying they had genetically modified human embryos, Kathy Niakan, a stem cell scientist from London’s Francis Crick Institute, was granted a license to carry out similar experiments. “The Human Fertilisation and Embryology Authority (HFEA) has approved a research application from the Francis Crick Institute to use new ‘gene editing’ techniques on human embryos,” Niakan’s lab said on Monday. It said the work carried out “will be for research purposes and will look at the first seven days of a fertilized egg’s development, from a single cell to around 250 cells”. The scientists will not be allowed to develop the modified embryos for clinical purposes or implant them into any women. Continue Reading →

Tracking down the ancestry of First Lady Michelle Obama

BY RACHEL SWARNS
ANCESTRY.CA

First Lady Michelle Obama always suspected that she had white ancestors. But she had no idea who they were. With DNA testing and research, I was able to solve that mystery and finally identify the white forbears who had remained hidden in her family tree for more than a century.

All across the country, growing numbers of people are turning to DNA testing as a tool to help unlock the secrets of their roots, using companies such as ancestry.com, among others. When I started researching my new book, “American Tapestry: The Story of the Black, White and Multiracial Ancestors of Michelle Obama,’’ I pored over historical documents that I found in local archives, courthouses and libraries as well as records that I found online on ancestry.com and other state and local databases. But I knew that DNA testing would be the only way to unearth the truth.

I suspected that Mrs. Obama’s white ancestors belonged to the white Shields family that had owned her great-great-great grandmother, Melvinia Shields. So I persuaded several descendants of the black and white Shields to do DNA testing.

The results showed that the two families were related. The DNA testing indicated that Melvinia’s owner’s son was the likely father of Melvinia’s biracial child, Dolphus Shields. (Dolphus Shields is the first lady’s great-great grandfather.)

But last month, members of both sides of the family – black and white — put aside the pain of the past. They got together for the very first time in Rex, Georgia at a ceremony to commemorate Melvinia’s life. They swapped family stories, posed for photographs, exchanged phone numbers and had a meal together.

It was something to see.

David Applin, who is Melvinia’s great-grandson, said the reunion was “wonderful.” And Jarrod Shields, who is the great-great-great grandson of Melvinia’s owner, described it as a day “my family will never forget.” Continue Reading →
