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.

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.
While some people with lung diseases receive transplants, donor organs remain in short supply. As an alternative, medications and other treatments can be used to manage symptoms, but no cure is available for disorders such as chronic obstructive pulmonary disease and cystic fibrosis. Researchers continue to seek better medications, often relying on testing in rodents. But these animal models may only partially capture the complexities of pulmonary diseases in humans, and they might not accurately predict the safety and efficacy of new drugs.
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.
“We think this is going to be very enabling for robotics,” says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT and the senior author of the study. “We’re building robotic functions onto the battery and starting to put these components together into devices.”
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.
Now, the same research group has applied the therapeutic strategy to damaged human cartilage cells. In the new study, the treatment activated the gene expression necessary to regenerate cartilage within just four hours. And, after only three days, the human cells produced protein components needed for cartilage regeneration.
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.
ROCHESTER, Minn. — Mayo Clinic scientists are using artificial intelligence (AI) and machine learning to analyze electroencephalogram (EEG) tests more quickly and precisely, enabling neurologists to find early signs of dementia among data that typically go unexamined.
The century-old EEG, during which a dozen or more electrodes are stuck to the scalp to monitor brain activity, is often used to detect epilepsy. Its results are interpreted by neurologists and other experts trained to spot patterns among the test’s squiggly waves.
In new research published in Brain Communications, scientists at the Mayo Clinic Neurology AI Program (NAIP) demonstrate how AI can not only speed up analysis, but also alert experts reviewing the test results to abnormal patterns too subtle for humans to detect. The technology shows the potential to one day help doctors distinguish among causes of cognitive problems, such as Alzheimer’s disease and Lewy body dementia. The research suggests that EEGs, which are more widely available, less expensive and less invasive than other tests to capture brain health, could be a more accessible tool to help doctors catch cognitive issues in patients early.
