Tel Aviv team develops RNA ‘missiles’ to directly target cancer cells

Posted by in categories: biotech/medical, innovation

A team of researchers at Tel Aviv University has developed a breakthrough RNA-based drug delivery system to target diseased cells that could improve the treatment of blood cancers, various types of solid cancers, different inflammatory diseases and viral diseases – including coronavirus.


“We are the first in the world to deliver the drug exclusively to cells that are currently relevant to the disease.”

Brain Circuit for Spirituality Identified

Posted by in categories: biotech/medical, neuroscience

Of the 88 neurosurgical patients, 30 showed a decrease in self-reported spiritual belief before and after neurosurgical brain tumor resection, 29 showed an increase, and 29 showed no change. Using lesion network mapping, the team found that self-reported spirituality mapped to a specific brain circuit centered on the PAG. The circuit included positive nodes and negative nodes — lesions that disrupted these respective nodes either decreased or increased self-reported spiritual beliefs.


Summary: A new study has identified a specific brain circuit centered in the periaqueductal gray that is linked to spiritual acceptance and religiosity.

How Pesticide Companies Corrupted the EPA and Poisoned America

“I realized that in the middle-dose group, which is the one that mattered for the no-effects level, they had conveniently left out one of the two baseline measurement days,” said Sheppard. “The outrageous thing was that the group they declared as NOEL was only that because they left out data from their analysis.” In a peer-reviewed paper published in October 2020, Sheppard and her colleagues concluded that “the omission of valid data without justification was a form of data falsification.”


In any case, bifenthrin was not the only pesticide that dodged testing to see if it presented dangers. The EPA’s pesticide office granted 972 industry requests to waive toxicity tests between December 2011 and May 2018, 89 percent of all requests made. Among the tests on pesticides that were never performed were 90 percent of tests looking for developmental neurotoxicity, 92 percent of chronic cancer studies, and 97 percent of studies looking at how pesticides harm the immune system.

By law, the companies that submit their products for review pay for these tests, and in a presentation about the waivers last year, Anna Lowit, a senior science adviser in the office, emphasized the savings to these companies: more than $300 million. Lowit also noted that animal lives were saved — a goal that the Trump administration and the chemical industry prioritized within the agency. The EPA developed the guidelines for waiving the tests along with BASF, Corteva, and Syngenta, pesticide manufacturers that all stand to benefit significantly from having their products bypass toxicity testing.

Moon-sized “zombie” star challenges what we know about celestial evolution

Posted by in categories: evolution, space

The star is only a little bit larger than Earth’s Moon, but more massive than the Sun and might be a Frankenstein zombie star.


Astronomers discovered the smallest and most massive white dwarf star, about the same size as Earth’s Moon with a mass greater than the Sun.

Gene Therapy Basics

Posted by in categories: biotech/medical, life extension

Not just the results, but the vector used. I’ll post the paper below.


In this video we cover an experiment where gene therapies to overexpress TERT and Follistatin were used in a mouse model. The mice saw a 41 and 32% increase in median life span. The study also used a novel viral vector, cytomegalovirus for the delivery. Please note that this a preprint which is not peer-reviewed yet.

Throwing an “Axion Bomb” Into a Black Hole Could Break a Fundamental Law of Physics

Posted by in categories: cosmology, physics

New research shows how the fundamental law of conservation of charge could break down near a black hole.

Singularities, such as those at the centre of black holes, where density becomes infinite, are often said to be places where physics ‘breaks down’. However, this doesn’t mean that ‘anything’ could happen, and physicists are interested in which laws could break down, and how.

Now, a research team from Imperial College London, the Cockcroft Institute and Lancaster University have proposed a way that singularities could violate the law of conservation of charge. Their theory is published in Annalen der Physik.
