Study shows how liver damage from stress and aging might be reversible
2024-06-26
DURHAM, N.C. – While the liver is one of the body’s most resilient organs, it is still vulnerable to the ravages of stress and aging, leading to disease, severe scarring and failure. A Duke Health research team now might have found a way to turn back time and restore the liver.
In experiments using mice and liver tissue from humans, the researchers identified how the aging process prompts certain liver cells to die off. They were then able to reverse the process in the animals with an investigational drug.
The finding, which ...
Bone stem cells with IFITM5 mutation get caught in a loop leading to osteogenesis imperfecta type V
2024-06-26
A study conducted by researchers at Baylor College of Medicine and collaborating institutions reveals the molecular events leading to osteogenesis imperfecta type V, a form of brittle bone disease caused by a mutation in the gene IFITM5.
The mutation blocks the normal development of bone stem cells into mature cells, which would form healthy bones. Instead, the mutation leads to the formation of bones that are extremely brittle. Children with this disorder have recurrent fractures, bone deformities, chronic pain and other complications. ...
Tai Chi reduces risk of inflammatory disease, treats insomnia among breast cancer survivors
2024-06-26

Shocked quartz reveals evidence of historical cosmic airburst
2024-06-26
(Santa Barbara, Calif.) — Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth’s atmosphere 12,800 years ago, causing a widespread climatic shift that, among other things, led to the abrupt reversal of the Earth’s warming trend and into an anomalous near-glacial period called the Younger Dryas.
Now, UC Santa Barbara emeritus professor James Kennett and colleagues report the presence of proxies associated with the cosmic airburst ...

The on-and-off affair in DNA
2024-06-26
Researchers led by Kannosuke Yabe, Asuka Kamio, and Soichi Inagaki of the University of Tokyo have discovered that in thale cresses histone H3 lysine-9 (H3K9) methylation, conventionally thought to be a mark of turning off gene transcription, can also turn on gene expression via the interactions of two other proteins and histone marks. The molecular mechanisms demonstrate that rather than functioning as a simple “off switch,” H3K9 methylation is more like a “dimmer switch” that fine-tunes DNA transcription. The discovery suggests there might be similar mechanisms in other ...

How do our memories last a lifetime? New study offers a biological explanation
2024-06-26
Whether it’s a first-time visit to a zoo or when we learned to ride a bicycle, we have memories from our childhoods kept well into adult years. But what explains how these memories last nearly an entire lifetime?
A new study in the journal Science Advances, conducted by a team of international researchers, has uncovered a biological explanation for long-term memories. It centers on the discovery of the role of a molecule, KIBRA, that serves as a “glue” to other molecules, thereby solidifying memory formation.
“Previous efforts to understand ...
Mechanical computer relies on kirigami cubes, not electronics
2024-06-26
North Carolina State University researchers have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic components. The system also includes a reversible feature that allows users to control when data editing is permitted and when data should be locked in place.
Mechanical computers are computers that operate using mechanical components rather than electronic ones. Historically, these mechanical components have been things like levers or gears. However, mechanical computers can also be made using structures that are multistable, meaning ...
Acting for a common goal with humanoid robots
2024-06-26
Genova (Italy), 26 June 2024 – Researchers at the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) have demonstrated that under specific conditions, humans can treat robots as co-authors of the results of their actions. The condition that enables this phenomenon is that a robot behaves in a human-like, social manner. Engaging in gaze contact and participating in a common emotional experience, such as watching a movie, are the key. The study was published in Science Robotics and paves the way for understanding and designing the optimal circumstances for humans and robots to collaborate in the same environment.
