Senescent Cell Therapies and Future Directions

Posted by in categories: biotech/medical, life extension

We wanted to bring your attention to a recent publication that discusses the topic of cellular senescence and the contributions of senescent cells to aging and disease [1].

What is perhaps the most interesting part of this paper is the section covering the potential future directions that researchers may take in managing senescent cell populations in order to mitigate age-related disease.

The author writes not only about the direct destruction of senescent cells via senolytic drugs but also about the modulation of the harmful secretions these cells produce, which are called the senescence-associated secretory phenotype (SASP).

Improbable Thruster Seems to Work by Violating Known Laws of Physics

Posted by in categories: energy, physics, satellites

Every action creates an equal and opposite reaction. It’s perhaps the best known law of physics, and Guido Fetta thinks he’s found a way around it.

According to classical physics, in order for something—like a spaceship—to move, conservation of momentum requires that it has to exert a force on something else. A person in roller skates, for example, pushes off against a wall; a rocket accelerates upward by propelling high-velocity combusted fuel downward. In practice, this means that space vessels like satellites and space stations have to carry up to half their weight in propellant just to stay in orbit. That bulks up their cost and reduces their useful lifetime.

Scientists find way to melt gold at room temperature

Posted by in category: physics

Melting gold normally requires temperatures upwards of 1,064° C (1,947° F), but physics is never quite that simple. A team of researchers has now found a way to melt gold at room temperature using an electric field and an electron microscope.

Infectious ‘Prions’ Found in the Eyes of Patients with Fatal Brain Disease

Posted by in categories: biotech/medical, neuroscience

People with the rare and fatal brain disorder Creutzfeldt-Jakob disease (CJD) show signs of the disease in their eyes, according to a new study.

The study found evidence of prions — the infectious proteins that cause the disease — in the eyes of nearly a dozen patients with CJD.

The findings suggest that patients’ eyes could potentially provide a “window” to the brain that may help researchers diagnose the disease early, if new eye tests are developed. [’Eye’ Can’t Look: 9 Eyeball Injuries That Will Make You Squirm].
