For it is they who are leading a charge towards a new frontier in medicine that will revolutionise our ‘healthspans’ — the number of years of good health we can expect to enjoy — and push back the worst effects of ageing.
The announcement this week that a new anti-ageing company, Altos Labs, which is based in the U.S. and UK, has been established to ‘hack’ the ageing process has reignited interest in the science of rejuvenation, an obsession that has spanned continents and the ages.

Snoring not only can cause a restless night for bedfellows, but it can also disturb the processes that affect brain health. Researchers found that reducing snoring may improve cognitive function in individuals with mild impairment.
Researchers from The University of Texas at Dallas and their colleagues have discovered that breathing rates while sleeping can be used to distinguish cognitively normal people from those who have mild cognitive impairment or Alzheimer’s disease.

Cancer cells send out nanotubes to suck mitochondria from immune cells, finds a November 18 study in Nature Nanotechnology. The pilfered organelles allow the cancer cells to replenish their power while weakening T cells—a finding that could lead to new avenues for assailing tumors.
“It’s surprising that the transfer of mitochondria happened between different cell types, intriguingly between immune cells and cancer cells,” writes cancer biologist Ming Tan of China Medical University in Taiwan, who was not involved in this study, in an email to The Scientist. While researchers have observed mitochondrial transfer between cells before, most cases occurred between two cells of the same type. “Moreover, the mitochondrial transfer appears to have a significant impact on tumor cells escaping from immune surveillance,” Tan adds. “This is exciting because [of] its potential therapeutic implications.”

Pfizer CEO Albert Bourla on Monday said a vaccine that targets the omicron variant of Covid will be ready in March, and the company’s already begun manufacturing the doses.
“This vaccine will be ready in March,” Bourla told CNBC’s “Squawk Box.” “We [are] already starting manufacturing some of these quantities at risk.”
Bourla said the vaccine will also target the other variants that are circulating. He said it is still not clear whether or not an omicron vaccine is needed or how it would be used, but Pfizer will have some doses ready since some countries want it ready as soon as possible.

California has more rooftops with solar panels than any other state and continues to be a leader in new installations. It is also first in terms of the percentage of the state’s electricity coming from solar, and third for solar power capacity per capita. However, former California governor Arnold Schwarzenegger has expressed concerns that California.

Imagine you could cure cancer by targeting one tiny gene. Imagine that same gene occurred in every major cancer, including breast, prostate, lung, liver and colon. Imagine that the gene is not essential for healthy activity, so you could attack it with few or no negative side effects.
Cancer biologist Yibin Kang has spent more than 15 years investigating a little-known but deadly gene called MTDH, or metadherin, which enables cancer in two important ways — and which he can now disable, in mice and in human tissue, with a targeted experimental treatment that will be ready for human trials in a few years. His work appears in two papers in today’s issue of Nature Cancer.
Most vertical farms are hydroponic (plant roots sit in shallow troughs of nutrient-rich water) or aeroponic (roots dangle in the air and are periodically misted). But Upward Farms uses aquaponics to fertilize its crops. What does that mean? In a nutshell, that plants are fertilized with fish poop.
To get a little more specific: besides microgreens, Upward Farms raises fish: mercury-free, antibiotic-free, hormone-free hybrid striped bass, in tanks that are separate from the trays of greens. Manure from the fish is collected and fed to the plants, making for a soil microbiome that’s more dense, fertile, and productive than that of most indoor farms, according to the company. Best of all, the company sells the fish to consumers, too.
Upward Farms claims its yields are two times above the industry average thanks to its ecological farming method, which keeps the microbial cell count in soil much higher than it would be with chemical fertilizers. “There’s a communication layer that’s been built in by millions of years of evolution between plants and microbes,” said Jason Green, Upward Farms’ CEO and cofounder. “Plants can say, ‘Hey, I’m stressed in this way, my environment is imperfect in this way, can you help me?’ and plants recruit microbes to their service.”
Space anemia is more serious than we thought.
Being in space causes the human body to destroy about 50% more red blood cells, leading to a potentially dangerous condition known as anemia. The effects persist even after astronauts return to Earth, according to a new study.
The study, led by researchers at the Ottawa Hospital and the University of Ottawa in Ontario, Canada, analyzed breath and blood samples of 14 astronauts before, during, and after their six-month missions aboard the International Space Station. The researchers found that the astronaut’s bodies destroyed about 54% more red blood cells than they would on Earth.
TALLAHASSEE, Florida — A London patient, Steve Verze, became the first to use a 3D-printed prosthetic eye in November 2021. Its advancements in aesthetics, durability and production process allude to an auspicious future for prosthetics. Yet, developing countries struggle regarding prosthetic accessibility and affordability. Losing a limb or organ in poverty is extremely impactful since access to prosthetic devices or assistance is rare.
A 3D Difference
Steve Verze made history by replacing his acrylic eye with a 3D-printed prosthetic. Since he was 20 years old, he has worn a prosthetic and expressed that he was always self-conscious wearing it. The difference between his previous eye and the 3D counterpart is wider than expected. Traditional prosthetic eyes take six weeks to finish due to hand painting acrylic. The 3D printing prosthetic takes two to three weeks in comparison. Acrylic eyes require an anesthetic for children due to the challenge of molding them to the eye socket. The 3D eye only uses digital scans and “is a true biomimetic and a more realistic prosthetic, with clearer definition and a real depth to the pupil.” The world’s first 3D-printed prosthetic eye shows advancements that expand the possibilities of prosthetics forever.
