Genetically engineered phage therapy has rescued a teenager on the brink of death

Posted by in categories: bioengineering, biotech/medical, genetics

It’s a remarkable story of recovery, but it’s unclear how useful this sort of therapy could become.

The background: Isabelle Holdaway had been given less than a 1% chance of survival after a lung transplant, carried out to combat the symptoms of cystic fibrosis, left her with an antibiotic-resistant infection. She had been sent home and was in a terrible physical condition: underweight, with liver failure, and with lesions on her skin from the infection.

A breakthrough: Her consultant at Great Ormond Street Hospital in London worked with a team at the University of Pittsburgh to develop an untested phage therapy. This treatment used a cocktail of three phages, which are viruses that solely attack and kill bacteria. Two of the three phages, selected from a library of more more than 10,000 kept at the University of Pittsburgh, had been genetically engineered to be better at attacking the bacteria. The therapy was injected into her bloodstream twice daily and applied to the lesions on her skin, according to Nature Medicine.

A Chip in My Hand Unlocks My House. Why Does That Scare People?

Posted by in categories: bioengineering, business, computing, transhumanism

Nearly 50 years ago, The New York Times—widely considered America’s paper of record—changed the media industry by creating the first modern Op-Ed page. Since then, their Opinion section has arguably become the most important voice for many public ideas that enter and change the world. Everyone from Heads of State to the globe’s most powerful business people to Nobel Prize winners to everyday citizens have written there when they had something essential to say about the times we live in. I’m super excited to share my first Op-Ed for The New York Times on #biohacking and the growing concern of legalizing implants. It’s a happy professional day for me, and an important step forward for the growing #transhumanism movement as we begin to enter mainstream culture.


Implant technology can change the world — unless politicians give in to the hysteria against it.

Hyperspectral camera captures wealth of data in an instant

Posted by in categories: bioengineering, drones, space

Standard snapshots from space don’t quite show Earth in all its glory. There’s so much more to see.

To reveal details impossible to observe with the naked eye, Rice University engineers are building a portable spectrometer that can be mounted on a small satellite, flown on an airplane or a drone or someday even held in the hand.

Bioengineer Tomasz Tkaczyk and his colleagues at Rice’s Brown School of Engineering and Wiess School of Natural Sciences have published the first results from a NASA-funded project to develop a small, sophisticated spectrometer with unusual versatility. Their paper appears in Optics Express.

Where is the Origin of Life on Earth?

Posted by in categories: bioengineering, biological, chemistry, evolution, physics

To answer the iconic question “Are We Alone?”, scientists around the world are also attempting to understand the origin of life. There are many pieces to the puzzle of how life began and many ways to put them together into a big picture. Some of the pieces are firmly established by the laws of chemistry and physics. Others are conjectures about what Earth was like four billion years ago, based on extrapolations of what we know from observing Earth today. However, there are still major gaps in our knowledge and these are necessarily filled in by best guesses.

We invited talented scientists to discuss their different opinions about the origin of life and the site of life’s origin. Most of them will agree that liquid water was necessary, but if we had a time machine and went back in time, would we find life first in a hydrothermal submarine setting in sea water or a fresh water site associated with emerging land masses?

Scientists ‘went rogue’ and genetically engineered two human babies—or at least claimed to

Posted by in categories: bioengineering, biotech/medical, genetics

In the past 24 hours, a story of potentially world-changing import has surfaced. First reported by the MIT Technology Review and then not long after by the Associated Press, who seem to have been sitting on the story for a while, the news that a Chinese scientist named He Jiankui led an unprecedented experiment to edit human embryos and see them carried to term rocked the genetics community. Here’s what you need to know about this evolving story.

The science

Besides He, the most important players in this story may be twin baby girls named Nana and Lulu. As far as we know the twins were edited as embryos using CRISPR-cas9, a gene editing tool. The stated purpose of the edit was to disable CCR5, a gene involved in allowing HIV to invade cells, which is how a virus infects a host.

Genetically engineered immune cells fight off deadly virus in mice

Posted by in categories: bioengineering, biotech/medical, genetics

Researchers may have demonstrated a novel way to protect us from some of the world’s deadliest viruses. By genetically engineering immune cells to make more effective antibodies, they have defended mice from a potentially lethal lung virus. The same strategy could work in humans against diseases for which there are no vaccines.

“It’s a huge breakthrough,” says immunologist James Voss of the Scripps Research Institute in San Diego, California, who wasn’t connected to the study.

Vaccines typically contain a disabled microbial invader or shards of its molecules. They stimulate immune cells known as B cells to crank out antibodies that target the pathogen. Not everyone who receives a vaccine gains protection, however. Some patients’ antibodies aren’t up to snuff, for instance. And researchers haven’t been able to develop vaccines against some microbes, such as HIV and the respiratory syncytial virus (RSV), which causes lung infections mainly in children and people with impaired immune systems.
