The new research harnesses previously unknown features of this ancient viral DNA, creating a biological clock to track a person’s age from the DNA’s chemical changes.

And the researchers now believe that new antiretroviral therapies, similar to those used to fight the HIV virus and AIDS, might one day help reverse the signs of aging.

‘Our findings indicate that retroelement clocks capture previously undetected facets of biological aging,’ said study co-author Dr Michael Corley, an assistant professor of immunology at Weill Cornell Medicine in New York.

Researchers describe their success in creating a mucus-based bioink for 3D printing lung tissue. This advancement could one day help study and treat chronic lung conditions. scitechupdates.com/mucus-based-bi…

Lung diseases kill millions of people around the world each year. Treatment options are limited, and animal models for studying these illnesses and experimental medications are inadequate. Now, writing in ACS Applied Bio Materials, researchers describe their success in creating a mucus-based bioink for 3D printing lung tissue. This advancement could one day help study and treat chronic lung conditions.

Newfound compound is as effective at treating infected skin wounds as is the antibiotic of last resort.

Jennifer Alexandra was 37 years old when she was diagnosed with tongue cancer and needed to have her tongue removed after doctors discovered a blueberry-sized tumor in her mouth.

“Space-based research has a long history of contributing to advancements on Earth,” said Dr. Lisa Carnell.

The International Space Station (ISS) has been a beacon of scientific and medical research ever since the station’s first module was launched in 1999, as astronauts continue to push the boundaries regarding microgravity research that has contributed to advancing science and medical knowledge back on Earth. To continue this, NASA and the ISS National Laboratory recently announced a partnership through the ISS National Lab Research Announcement (NLRA) 2024-09: Igniting Innovation: Science in Space to Cure Disease on Earth that will provide up to $4 million with the goal of helping to advance disease diagnosis and treatment back on Earth.

Through collaboration between government agencies, industry, and academia, the NLRA hopes to accomplish several objectives pertaining to developing medical technologies on Earth, including disease mechanism models, population and disease diversity, drug discovery & development, drug delivery, and drug resistance. This announcement comes after the ISS National Laboratory announced in July 2024 that five projects were selected for the Cancer Research in Space for Life on Earth with the goal of providing $7 million in grants to advance cancer research in microgravity onboard the ISS.

Engineers have designed a tiny battery, smaller than a grain of sand, to power microscopic robots for jobs such as drug delivery or locating leaks in gas pipelines.

A tiny battery designed by MIT engineers could enable the deployment of cell-sized, autonomous robots for drug delivery within in the human body, as well as other applications such as locating leaks in gas pipelines.

The new battery, which is 0.1 millimeters long and 0.002 millimeters thick — roughly the thickness of a human hair — can capture oxygen from air and use it to oxidize zinc, creating a current with a potential of up to 1 volt. That is enough to power a small circuit, sensor, or actuator, the researchers showed.

New study shows ‘#Dancing #Molecules’ can #Regenerate #Cartilage in 3 days.

In the new study, the treatment activated gene expression needed to regenerate cartilage in just 4h. After 3 days, cells produced protein components for cartilage regeneration…

In November 2021, Northwestern University researchers introduced an injectable new therapy, which harnessed fast-moving “dancing molecules,” to repair tissues and reverse paralysis after severe spinal cord injuries.

The pursuit of a cure for Alzheimer’s disease is becoming an increasingly competitive and contentious quest with recent years witnessing several important controversies.

In July 2022, Science magazine reported that a key 2006 research paper, published in the prestigious journal Nature, which identified a subtype of brain protein called beta-amyloid as the cause of Alzheimer’s, may have been based on fabricated data.

One year earlier, in June 2021, the US Food and Drug Administration had approved aducanumab, an antibody-targeting beta-amyloid, as a treatment for Alzheimer’s, even though the data supporting its use were incomplete and contradictory.
