Chinese Lab Created New Coronavirus, 100% Mortality Rate in Human Transgenetic Mice

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

According to a paper submitted for peer review on January 4th, 2024, Lethal Infection of Human ACE2-Transgenic Mice Caused by SARS-CoV-2-related Pangolin Coronavirus GX_P2V(short_3UTR), a new lab-created coronavirus has the potential to kill 100% of those infected with the virus within 8 days of infection.

The mice were genetically modified to express the human ACE2 receptor. This is the receptor responsible for allowing coronavirus to gain cellular entry. The lab infected mice with a coronavirus engineered from a strain found in pangolins. Pangolins are medium-sized animals growing to 12 — 30 inches in length and have the appearance of a scale-plated anteater.

Researchers monitored the mice for signs of infection by recording body weight, taking tissue samples, and monitoring for other symptoms. By the third day post-infection, tissue samples from the infected mice had a significant amount of viral RNA in the brain, eye, lung, and nasal tissue.

Retinal thinning linked to Parkinson’s disease progression and cognitive decline

Posted by in categories: biotech/medical, neuroscience

👁️ 🧠 🔬


A recent study published in the journal Npj Parkinson’s Disease investigated whether increased thinning rate in the parafoveal ganglion cell-inner plexiform layer (pfGCIPL) and peripapillary retinal nerve fiber layer (pRNFL) indicates the progression of the Parkinson’s disease (PD).

The fountain of youth is … a T cell?

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

“If we give it to aged mice, they rejuvenate. If we give it to young mice, they age slower. No other therapy right now can do this.”


The fountain of youth has eluded explorers for ages. It turns out the magic anti-aging elixir might have been inside us all along.

Cold Spring Harbor Laboratory (CSHL) Assistant Professor Corina Amor Vegas and colleagues have discovered that T cells can be reprogrammed to fight aging, so to speak. Given the right set of genetic modifications, these white blood cells can attack another group of cells known as senescent cells. These cells are thought to be responsible for many of the diseases we grapple with later in life.

Researchers develop nanofiber-based drug delivery system for skin cancer

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

Treating complex diseases such as skin cancer often requires simultaneous administration of multiple anticancer drugs. The delivery of such life-saving therapeutic drugs has evolved with the rise of nanotechnology-based drug carriers. Nanoplatforms offer numerous advantages, including increased bioavailability, lowered dosages, and improved biodistribution.

Now a team of researchers, led by Professor Myoung-Hwan Park from Sahmyook University in South Korea, has developed a light-responsive nanofiber-based novel (DDS) targeting skin cancer. The DDS was studied in a detailed manner, beginning with its synthesis and characterization to its biocompatibility, drug release profile, and efficacy against skin cancer. These research findings are published in the Journal of Drug Delivery Science and Technology.

Explaining the motivation behind the present research, Dr. Park states, “Conventional drugs can be efficiently delivered in a controlled manner through nano-engineered platforms, and such an approach increases the overall effectiveness of the treatment. This approach improves outcomes in cancer drug therapy by ensuring precise delivery at optimal dosages.”

Your Body Has Its Own Built-In Ozempic

Posted by in categories: biotech/medical, food

This is good info but I’d like to do it naturally. I wonder if healing my gut biome with pro and prebiotics can help. There’s been psychiatric side effects with ozempic in a few cases. There’s often some kind of side effect when not natural but some people could benefit if monitored by a doctor.


Popular weight-loss and diabetes drugs, such as Ozempic and Wegovy, target metabolic pathways that gut microbes and food molecules already play a key role in regulating.

Innovative silicon nanochip can reprogram biological tissue in living body

Posted by in categories: biotech/medical, computing, engineering, life extension, neuroscience, singularity

Year 2021 Biocomputing is the future for the biological singularity because we could control all inputs and outputs of our bodies even evolve them eventually.


A silicon device that can change skin tissue into blood vessels and nerve cells has advanced from prototype to standardized fabrication, meaning it can now be made in a consistent, reproducible way. As reported in Nature Protocols, this work, developed by researchers at the Indiana University School of Medicine, takes the device one step closer to potential use as a treatment for people with a variety of health concerns.

The technology, called tissue nanotransfection, is a non-invasive nanochip device that can reprogram tissue function by applying a harmless electric spark to deliver specific genes in a fraction of a second. In laboratory studies, the device successfully converted into to repair a badly injured leg. The technology is currently being used to reprogram tissue for different kinds of therapies, such as repairing caused by stroke or preventing and reversing nerve damage caused by diabetes.

Researchers uncover molecular mechanisms behind effects of MXene nanoparticles on muscle regeneration

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

Tissue engineering, which involves the use of grafts or scaffolds to aid cell regeneration, is emerging as a key medical practice for treating volumetric muscle loss (VML), a condition where a significant amount of muscle tissue is lost beyond the body’s natural regenerative capacity. To improve surgical outcomes, traditional muscle grafts are giving way to artificial scaffold materials, with MXene nanoparticles (NPs) standing out as a promising option.

MXene NPs are 2D materials primarily composed of transition-metal carbides and nitride. They are highly electrically conductive, can accommodate a wide range of functional groups, and have stacked structures that promote cell interactions and growth. While there have been practical demonstrations in the laboratory showcasing their ability to promote the reconstruction of skeletal muscles, the specific mechanism by which they do so remains unclear.

To address this gap, Associate Professor Yun Hak Kim from the Department of Anatomy and Department of Biomedical Informatics, alongside Professors Suck Won Hong, and Dong-Wook Han from the Department of Cogno-Mechatronics Engineering at Pusan National University developed nanofibrous matrices containing MXene NPs as scaffolds. They used DNA sequencing to reveal the genes and biological pathways activated by MXene NPs to aid in muscle regeneration.

ITMO Researchers Develop Alternative Liquid-Based THz Radiation Source

Posted by in categories: biotech/medical, security

Polar liquids, such as water, are powerful absorbents of electromagnetic waves in the terahertz range. For that reason, they were never considered as potential THz radiation sources. Last year, researchers from ITMO University and the University of Rochester proved that liquid-based radiation sources can be no less effective than traditional ones. In their new study, the staff of ITMO University’s Laboratory of Femtosecond Optics and Femtotechnologies present their research on the generation of THz radiation in liquid jets of various kinds. In the future, these findings can be used to create new alternative sources of THz radiation. The research was published in Optics Express.

Terahertz technologies: spectroscopy, security, biomedicine, and non-destructive diagnostics

Terahertz radiation is a type of electromagnetic radiation located within the frequency spectrum between infrared and radio. It passes well through a variety of materials, such as wood, plastic, and ceramics.
