Increased Longevity and Overpopulation

Posted by in categories: biotech/medical, life extension

Any discussion of rejuvenation biotechnology almost certainly includes the subject of and the objection that medical advances that directly address the various processes of aging will lead to an overpopulated world. Such dire predictions are a common theme in many discussions involving advances in medicine that could increase human lifespans.

Overpopulation is a word that gives the simple fact of population growth a negative connotation. It implies that an increase in the number of people will harm our lives in different ways, such as famine, scarcity of resources, excessive population density, increased risks of infectious diseases, and harm to the environment.

Bacterial Molecule Can Slow Sjögren’s Progression, Preclinical Study Suggests

Posted by in categories: biotech/medical, genetics

Oral treatment with a bacterial protein known as colonization factor antigen I (CFA/I) fimbriae, from Escherichia coli bacteria, has been shown to protect against several autoimmune diseases, including arthritis and type 1 diabetes. Another bacteria, called Lactococcus lactis, was recently adapted to express CFA/I fimbriae. These bacteria were shown to effectively suppress inflammation by the induction of regulatory T-cells (Tregs) — which are negative regulators of the immune system, meaning they work to shut down excessive inflammatory responses.


Oral treatment with a molecule produced by bacteria, called colonization factor antigen I, can reduce or halt the progression of Sjögren’s syndrome, a mouse study suggests.

Researchers believe these findings provide the basis for future testing in patients with Sjögren’s.

Beehives Are Held Together by Their Mutual Gut Microbes

Posted by in category: biotech/medical

New research shows that members of a bee colony all have the same gut microbiome, which controls their smell—and thus their ability to separate family from foe.

Rejuvenate Bio banks $10M to advance gene therapy for aging in humans and dogs

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

Rejuvenate Bio’s treatment is a gene therapy that dials up expression of the genes sTGFbetaR2 and FGF21 to reduce levels of the cytokine TGF-beta1 and boost levels of the hormone FGF21, respectively. Both genes are associated with longevity.

“What we have seen from using a combination of two genes is the ability to affect multiple age-related diseases at once,” Oliver said.

Rejuvenate Bio published data in November 2019 showing that targeting these two genes in mice reduced kidney atrophy and reversed weight gain and Type 2 diabetes. The company had given extra copies of those genes, alone and in combination with each other and another gene called alpha-Klotho to see if they could boost the mice’s health and life spans. It found out that more isn’t necessarily better, as mice that were given all three genes together fared worse than the other animals did.

MagicDNA: Tiny, Complex DNA Robots Designed in Minutes Instead of Days

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

Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics.

Researchers took a big step toward that future by developing a new tool that can design much more complex DNA robots and nanodevices than were ever possible before in a fraction of the time.

Global tally of COVID-19 cases top 142 million as India’s surge raises the alarm

Posted by in category: biotech/medical

The number of confirmed cases of the coronavirus-borne illness COVID-19 climbed above 142 million on Tuesday, and India remained a hot spot, recording more than 250000 new infections and over 1700 deaths in the past 24 hours alone.

India has the second-highest case tally in the world after the U.S. with more than 15 million cases, according to data aggregated by Johns Hopkins University. The country of more than 1.3 billion has suffered more than 180000 deaths — and experts say these numbers are likely an undercount, the Associated Press reported.

The capital New Delhi entered lockdown again on Monday in an effort to curb a surge in cases that has hospitals overflowing, intensive-care units full and oxygen in short supply.

Ultraviolet-LED Maker Demonstrates 30-Second Coronavirus Kill

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

Circa 2020


Robots and stranger machines have been using a particular band of ultraviolet light to sterilize surfaces that might be contaminated with coronavirus. Those that must decontaminate large spaces, such as hospital rooms or aircraft cabins, use large, power-hungry mercury lamps to produce ultraviolet-C light. Companies around the world are working to improve the abilities of UV-C producing LEDs, to offer a more compact and efficient alternative. Earlier this month, Seoul Viosys showed what it says is the first 99.9 percent sterilization of SARS-COV-2, the coronavirus that causes COVID-19, using ultraviolet LEDs.

UV LEDs are deadly to viruses and bacteria, because the 100–280 nanometer wavelength C-band shreds genetic material. Unfortunately, it’s also strongly absorbed by nitrogen in the air, so sources have to be powerful to have an effect at a distance. (Air is such a strong barrier, that the sun’s UV-C doesn’t reach the Earth’s surface.) Working with researchers at Korea University, in Seoul, the company showed that its Violed LED modules could eliminate 99.9 percent of the SARS-COV-2 virus using a 30-second dose from a distance of three centimeters.
