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.”

Goldman Sachs asks in biotech research report: ‘Is curing patients a sustainable business model?’

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

“The potential to deliver ‘one shot cures’ is one of the most attractive aspects of gene therapy, genetically-engineered cell therapy and gene editing. However, such treatments offer a very different outlook with regard to recurring revenue versus chronic therapies,” analyst Salveen Richter wrote in the note to clients Tuesday. “While this proposition carries tremendous value for patients and society, it could represent a challenge for genome medicine developers looking for sustained cash flow.”

🤔


Goldman Sachs warns sales from the most successful disease treatments are difficult to maintain.

CRISPR gene therapy, ultrasound and drugs team up against liver cancer

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

Researchers in China have developed a new three-pronged method to fight liver cancer that shows promise in tests in mice. The technique combines drugs and CRISPR-Cas9 gene editing into lipid nanoparticles, then activates them with ultrasound.

One emerging treatment against cancer is known as sonodynamic therapy (SDT), which involves delivering drugs to the tumor and then activating them with ultrasound pulses. That produces reactive oxygen species (ROS) that can induce oxidative stress on the cancer cells to kill them. Unfortunately, cancer can counter this attack with antioxidant enzymes, reducing the method’s efficiency.

So for the new study, the researchers investigated a way to remove that defense system. The team suspected that they could use CRISPR to switch off a gene called NFE2L2, which cancer cells use to set off their antioxidant defenses. The team packaged both the CRISPR machinery and the ROS-producing drugs into lipid nanoparticles, which could be activated with ultrasound pulses.

New Imaging Method Visualizes Blood Flow in the Brain Down to a Single Blood Cell

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

Researchers from the Skolkovo Institute of Science and Technology and Saratov State University have come up with an inexpensive method for visualizing blood flow in the brain. The new technique is so precise it discerns the motions of individual red blood cells — all without the use of toxic dyeing agents or expensive genetic engineering. The study was published in The European Physical Journal Plus.

To understand more about how the brain’s blood supply works, researchers map its blood vessel networks. The resulting visualizations can rely on a variety of methods. One highly precise technique involves injecting fluorescent dyes into the blood flow and detecting the infrared light they emit. The problem with dyes is they are toxic and also may distort mapping results by affecting the vessels. Alternatively, researchers employ genetically modified animals, whose interior lining of blood vessels is engineered to give off light with no foreign substances involved. Both methods are very expensive, though.

Researchers from Skoltech and Saratov State University have devised an inexpensive method for visualizing even the smallest capillaries in the brain. The method — which integrates optical microscopy and image processing — is dye-free and very fine-grained, owing to its ability to detect each and every red blood cell travelling along a blood vessel. Since the number of RBCs in capillaries is not that high, every cell counts, so this is an important advantage over other methods, including dye-free ones.
