I am going home :3.


Everybody wants a wormhole. I mean, who wants to bother traveling the long-and-slow routes throughout the universe, taking tens of thousands of years just to reach yet another boring star? Not when you can pop into the nearest wormhole opening, take a short stroll, and end up in some exotic far-flung corner of the universe.

There’s a small technical difficulty, though: Wormholes, which are bends in space-time so extreme that a shortcut tunnel forms, are catastrophically unstable. As in, as soon as you send a single photon down the hole, it collapses faster than the speed of light.

A gene called Lipocalin 2 is a major culprit in triple-negative breast cancer, an aggressive form of the disease for which there are few effective, targeted treatments. A team of researchers at Boston Children’s Hospital has developed an innovative way to knock out the gene using the editing system CRISPR and has shown its potential for treating triple-negative breast tumors in mice.

But to make CRISPR work in breast tumors, the researchers had to figure out a way to deliver the technology into breast cancer cells without using a virus or something else that might cause off-target side effects. So they encapsulated it in nanoparticles and targeted it at ICAM-1, a molecule expressed on breast cancer cells.

The encapsulated CRISPR system knocked out Lipocalin 2 with 81% efficiency in tumor samples, and when injected into mouse models of triple-negative breast cancer, it slowed tumor growth by 77%. The researchers reported the results in the journal Proceedings of the National Academy of Sciences.

In February, an artificial intelligence lab cofounded by Elon Musk informed the world that its latest breakthrough was too risky to release to the public. OpenAI claimed it had made language software so fluent at generating text that it might be adapted to crank out fake news or spam.

On Thursday, two recent master’s graduates in computer science released what they say is a re-creation of OpenAI’s withheld software onto the internet for anyone to download and use.

Aaron Gokaslan, 23, and Vanya Cohen, 24, say they aren’t out to cause havoc and don’t believe such software poses much risk to society yet. The pair say their release was intended to show that you don’t have to be an elite lab rich in dollars and PhDs to create this kind of software: They used an estimated $50,000 worth of free cloud computing from Google, which hands out credits to academic institutions. And they argue that setting their creation free can help others explore and prepare for future advances—good or bad.

The journal club will be returning on 27th August with your host Dr. Oliver Medvedik and special guest Alexander Tyshkovskiy, a Ph.D. student who works at the Gladyshev Lab at Brigham and Women’s Hospital, Harvard Medical School, Boston. The topic for the journal club this month will be the recent paper, “Identification and Application of Gene Expression Signatures Associated with Lifespan Extension” published in Cell Metabolism. This study is Alexander Tyshkovskiys project and forms part of his Ph.D. so we are fortunate to have him joining us on the show to talk us through this fascinating study.

In a recent study, a team from the Neurobiota Research Center in Korea has discovered that reducing gut dysbiosis partially alleviates the cognitive impairment associated with Alzheimer’s disease. This may seem puzzling, as the gut and the brain are separate and relatively distant organs, but this research makes sense in the context of chronic inflammation.

Inflammaging

Under normal circumstances, inflammation is a short-term measure in response to infection: immune cells are directed towards the inflamed area and handle the infection, and then the inflammation dies down. However, chronic inflammation causes harm to our organs; it is the main form of altered intercellular communication, which is one of the hallmarks of aging. The protein complex NF-kB, the master regulator of inflammation, is the main culprit of inflammaging, and it is specifically discussed in this paper.
