DNA sequencing solves mystery of earliest hybrid animal’s identity

Posted by in categories: bioengineering, biotech/medical

Bronze Age bioengineers created the earliest hybrid animal — a majestic horselike creature known as a kunga that had a donkey mom, a Syrian wild ass for a father and lived 4,500 years ago, according to new research based on the sequencing of DNA from the animal’s skeleton.

Descriptions and imagery in Mesopotamian art and texts portray a powerful animal that pulled war wagons into battle and royal vehicles in parades. Its true identity, however, had long puzzled and divided archaeologists. Domesticated horses didn’t arrive in the region, sometimes referred to as the Fertile Crescent, until 4,000 years ago.

New electroactive microrobots can create their own bone

Posted by in categories: bioengineering, biotech/medical, robotics/AI

One possible application of interest to researchers is bone healing. The idea is that the soft material, powered by the electroactive polymer, will be able to maneuver in spaces of complicated bone fractures and expand. When the material hardens, it can form the basis for building new bones. In their study, the researchers demonstrate that the material can wrap itself around chicken bones, and the artificial bone that develops later grows along with the animal’s bone. The developed biohybrid variable-stiffness actuators can be used in soft (micro-)robotics and as potential tools for bone repair or bone tissue engineering.

“By controlling how the material turns, we can make the microrobot move in different ways, and also affect how the material unfurls in broken bones. We can embed these movements into the material’s structure, making complex programs for steering these robots unnecessary”, says Edwin Jager.

These Were Our Favorite Tech Stories From Around the Web in 2021

Posted by in categories: bioengineering, biotech/medical, blockchains, chemistry, cryptocurrencies, internet, mathematics, robotics/AI

Tech companies continued to draw criticism for their roles in political and social scandals, most notably when whisteblower and former Facebook employee Frances Haugen testified to lawmakers. Undeterred, Facebook rebranded itself Meta and said it would now focus on building the metaverse. Twitter CEO Jack Dorsey stepped down and likewise changed the name of his company Square to Block in a not-so-subtle nod to the blockchain.

Meanwhile, volatile cryptocurrencies set new records, their prices jumping and crashing on a tweet. NFTs, a once-obscure type of cryptoasset, went on an eye-watering tear as redditors pushed meme stocks skyward. It was also the year of ever-bigger AI. Machine learning models surpassed a trillion parameters, designed computer chips, and tackled practical problems in biology, math, and chemistry. Elsewhere, billionaires went to space, regular folks bought 3D printed houses, fusion power attracted billions in investment, gene editing trials hit their stride, and “flying car” companies hit the New York Stock Exchange.

For this year’s list of fascinating stories in tech and science, we sifted our Saturday posts and selected articles that looked back to where it all began, glanced ahead to what’s coming, or otherwise stood out from the chatter to stand the test of time.

Dr. Irina Conboy — Rejuvenating Effects of Plasma Dilution

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

2 big points from this. 1. Plasma dilution does reverse aging but a bit and the next question will be can it be done over and over to make you younger in steps. 2. She mentions wrapping up human test results and hopes to give the results at some point.


At the EARD 2021 conference, Dr. Irina Conboy discusses the rejuvenating effects of plasma dilution in old mice. Dr. Conboy also explains why she believes that the path of rejuvenation is through tissue maintenance and repair, not preventing tissue damage.

New Biotechnology that will Cure Aging by 2030

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

A combination of soon-to-be released Biotechnology is expected to extend of lifespans almost tenfold with the help through emerging technologies such as CRISPR or Senolytics. These Anti Aging treatments are meant to stop and even reverse the aging process so that anyone could get young and healthy again. Many companies such as SENS or Jeff Bezos, but even countries like Japan are working on it to deal with an aging population.

Humans Might Need Artificial Gravity for Space Travel

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

Despite the fact that floating around in space looks like a certified blast, it’s not something the human body is optimized for. In order to make these trips possible, scientists are going to have to figure out how to mimic Earth’s gravity in space.

We evolved with gravity constantly pulling on us at a rate of about 9.8 m/s2, or 1 g. Our bodies are built in a way that takes that into account. Our rigid bones can hold us up, our cardiovascular system can pump blood to and from our extremities, our vestibular system in our ears keeps us balanced, and so on. Our bodies are also good at adapting to our needs, which means when you take gravity away the body starts to change. Bones lose mineral density, hearts weaken, and the vestibular system shuts off because suddenly there is no “up” anymore. So long as the body stays in space these changes aren’t really a problem, but coming back to Earth and readapting to 1 g can be painful and disorienting.

Engineered particles efficiently deliver gene editing proteins to cells in mice

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

Gene editing approaches promise to treat a range of diseases, but delivering editing agents to cells in animal models and humans safely and efficiently has proven challenging. Now, researchers led by a team at the Broad Institute of MIT and Harvard have developed a way to get gene editing proteins inside cells in animal models with high enough efficiency to show therapeutic benefit.

In new work published in Cell, the team shows how they have engineered virus-like particles to deliver base editors — proteins that make programmable single-letter changes in DNA — and CRISPR-Cas9 nuclease, a protein that cuts DNA at targeted sites in the genome. In collaboration with ​​research teams led by Krzysztof Palczewski at the University of California, Irvine, and Kiran Musunuru at the Perelman School of Medicine at the University of Pennsylvania, the team used their particles, called engineered virus-like particles (eVLPs), to disable a gene in mice that can be associated with high cholesterol levels, and partially restored visual function to mice harboring a mutation that causes genetic blindness.


Researchers have developed virus-like particles that deliver therapeutic levels of protein to animal models of disease.

US man recovering after ‘breakthrough’ pig heart transplant

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

A man with terminal heart disease is responding well three days after being given a genetically modified pig heart in a first-of-its-kind surgery, his doctors reported on Monday.
The surgery, performed by a team at the University of Maryland Medicine in the United States, is among the first to demonstrate the feasibility of a pig-to-human heart transplant, a field made possible by new gene editing tools.
If proven successful, scientists hope pig organs could help alleviate shortages of donor organs.
For David Bennett, a 57-year-old from Maryland, the heart transplant was his last option.

Al Jazeera’s Barbara Angopa reports.

Did aliens genetically engineer humans 780,000 years ago?

Posted by in categories: bioengineering, cosmology, evolution, genetics, neuroscience

The first humans emerged on Earth about 4 million years ago, but new evidence from the study of human evolution has revealed compelling evidence that a small group of these hominins was genetically modified by ancient alien visitors to create the first Homo sapiens.

Researcher and author Daniella Fenton has thoroughly analyzed humanity’s earliest origins and its sudden acceleration in brain development nearly 800,000 years ago, and this research has led to a major revelation.

“Homo sapiens is the creation of ancient astronauts who came through a wormhole in the Pleiades star cluster more than 780,000 years ago.”
