Harvard Rewinds the Biological Clock of Time

Posted by in categories: bioengineering, biological, DNA, health, life extension, science, transhumanism

Investigators at Harvard Medical School have identified the key cellular mechanisms behind vascular aging and its effects on muscle health, and they have successfully reversed the process in animals.

The scientists used a chemical compound that’s an NAD+ booster called NMN which plays a critical role in repairing cellular DNA as well as maintaining cell vitality to test what would happen.

Could reversing the aging of blood vessels hold the key to restoring youthful vitality? If the old adage “you are as old as your arteries” reigns true then the answer is yes, at least in mice.

Major research reveals CRISPR gene-editing could increase cancer risk in cells

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

Two recently published studies are raising new concerns that the breakthrough CRISPR-Cas9 gene editing system could potentially trigger an increased cancer risk in cells edited using the technique. With human trials using the gene-editing technique set to commence this year, the scientists behind these new studies urge researchers to be aware of this newly discovered and dangerous cancer-driving mechanism.

It has been less than a decade since the revolutionary CRISPR-Cas9 gene-editing technique was discovered, allowing scientists an unprecedented way to accurately edit DNA. For the most part, the technique has proved promising, safe and effective. Last year, a controversial study was published claiming the technique could introduce unintended, off-target mutations, but after a flurry of criticism attacking the veracity of the work it was ultimately retracted.

These two new studies raise entirely new concerns regarding the technique’s potential for triggering cancer in edited cells. One study comes from a collaboration between the University of Cambridge and the Karolinska Institutet, while the other is led by a team of researchers at pharmaceutical company Novartis.

Starch can replace normal plastic in food packaging

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

Eventually all petroleum-based material in food packaging will have to be replaced with bio-based material. Research done at Karlstad University shows that a mixture of starch and other polymers forms an equally effective protective barrier.

“Food packaging has to protect and extend the of food, and should also work during transport,” says Asif Javed, doctor in Chemical Engineering at Karlstad University. “To meet these demands, a protective barrier is needed in paper-based packing such as those used for juice or dairy.”

Crispr Fans Fight for Egalitarian Access to Gene Editing

Posted by in categories: bioengineering, biotech/medical, ethics, governance, health

A journalist, a soup exec, and an imam walk into a room. There’s no joke here. It’s just another day at CrisprCon.

On Monday and Tuesday, hundreds of scientists, industry folk, and public health officials from all over the world filled the amphitheater at the Boston World Trade Center to reckon with the power of biology’s favorite new DNA-tinkering tool: Crispr. The topics were thorny—from the ethics of self-experimenting biohackers to the feasibility of pan-global governance structures. And more than once you could feel the air rush right out of the room. But that was kind of the point. CrisprCon is designed to make people uncomfortable.

“I’m going to talk about the monkey in the room,” said Antonio Cosme, an urban farmer and community organizer in Detroit who appeared on a panel at the second annual conference devoted to Crispr’s big ethical questions to talk about equitable access to gene editing technologies. He referred to the results of an audience poll that had appeared moments before in a word cloud behind him, with one bigger than all the others: “eugenics.”

8 Amazing CRISPR gene editing projects that could change life as we know it.


Since it burst onto the scene a decade ago, CRISPR-Cas9 has shaken the field of genetics to its core. Offering a new genomic editing tool that’s faster, cheaper and more accurate than previous approaches, it opens up an astonishing breadth of possible applications.

World’s first 3D-printed cornea made from algae and human stem cells

Posted by in categories: 3D printing, bioengineering, biotech/medical, cyborgs, transhumanism

The human eye is a remarkably sophisticated organ and like the lens to a camera, it’s the cornea that focuses the flood of photons into a perceptible image. But for an estimated 15 million people around the world, eye disease and trauma make surgery the only path to clear vision.

In the next few years, artificial corneas may become more accessible thanks to new research out of Newcastle University in the United Kingdom. There, researchers mixed stem cells from the cornea of a healthy donor with collagen and algae molecules to create a bio-ink, which they 3D-printed into an artificial cornea. The research is currently just a proof-of-concept but lays the groundwork for future techniques to create low-cost, easy-to-produce bionic eyes.

Live forever or die trying: Meet the biohackers who fear their work could get them killed

Posted by in categories: bioengineering, biotech/medical, life extension, transhumanism

Long story in The Independent: https://www.independent.co.uk/…/biohacking-transhumanism-aa… #transhumanism #biohacking


On the morning of 29 April, staff at the Soulex spa in Washington DC discovered the lifeless body of one of its clients lying face down in a sensory deprivation tank. The body was that of 28-year-old Aaron Traywick, who less than three months earlier had injected himself live on stage at an event in Austin, Texas, with an untested gene therapy that he claimed could cure herpes.

A sensor could monitor gut health via engineered bacteria

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

Esearchers have devised a new way to get a sneak peek into what’s going on deep in your digestive system, creating a swallowable sensor that, with the help of engineered bacteria and a tiny electrical circuit, can detect the presence of molecules that might be signs of disease and then beam the results to a smartphone app.

The device, which scientists validated in pigs, remains a prototype and needs to be refined before it could be used in people. But the researchers, who reported their work Thursday in the journal Science, combined innovations in synthetic biology and microelectronics to create a modular platform that could be adapted to identify a wide range of molecules.
