What. The. Heck. Did you see that? Simone Biles appears to defy the laws of physics with this epic tumbling pass from the 2019 US Gymnastics Championships. It’s called a triple-double. That means she rotates around an axis going through her hips twice while at the same time rotating about an axis going from head to toe THREE times. Yes, it’s difficult—but it doesn’t defy physics, it uses physics.

Today, we have to share some bad news about Organovo and its liver tissue bioprinting program.

Dark matter most likely makes up an incredible 80 percent of the universe’s mass. But this single fact is the extent of our knowledge about this mysterious, all pervasive substance, with scientists unsure exactly what it is and how it came to be. Now a groundbreaking study has revealed dark matter may be even more bizarre than first thought, as its origin may have actually pre-dated the beginning of the Universe – the Big Bang.

Growing evidence suggests that certain types of bacteria are capable of causing colorectal cancers, indicating that a sub-set of these cancers could be the result of infectious disease.

But understanding how bacteria interact in the human gut – our microbiome — has been challenging because of the complex microbial mixture of “good” and “bad” bacteria.

Over a decade ago, French scientists discovered a pathway in certain strains of E. coli, a bacterium normally found in 90% of humans, that is “genotoxic” – toxic to DNA – causing tumor formation and colorectal cancer in mice.

What is reality and how do we know? For many the answer is simple: What you see — hear, feel, touch, and taste — is what you get.

Your skin feels warm on a summer day because the sun exists. That apple you just tasted sweet and that left juices on your fingers, it must have existed. Our senses tell us that reality is there, and we use reason to fill in the blanks — that is, we know the sun doesn’t cease to exist at night even if we can’t see it.

But cognitive psychologist Donald Hoffman says we’re misunderstanding our relationship with objective reality. In fact, he argues that evolution has cloaked us in a perceptional virtual reality. For our own good.

If you want a vision of the future, imagine a thousand bots screaming from a human face – forever (apologies to George Orwell). As U.S. policymakers remain indecisive over how to prevent a repeat of the 2016 election interference, the threat is looming ever more ominous on the horizon. The public has unfortunately settled on the term “bots” to describe the social media manipulation activities of foreign actors, invoking an image of neat rows of metal automatons hunched over keyboards, when in reality live humans are methodically at work. While the 2016 election mythologized the power of these influence-actors, such work is slow, costly, and labor-intensive. Humans must manually create and manage accounts, hand-write posts and comments, and spend countless hours reading content online to signal-boost particular narratives. However, recent advances in artificial intelligence (AI) may soon enable the automation of much of this work, massively amplifying the disruptive potential of online influence operations.

This emerging threat draws its power from vulnerabilities in our society: an unaware public, an underprepared legal system, and social media companies not sufficiently concerned with their exploitability by malign actors. Addressing these vulnerabilities requires immediate attention from lawmakers to inform the public, address legal blind spots, and hold social media companies to account.

Fighting Antibiotic Resistance By Repurposing Old Drugs : Shots — Health News Scientists discovered that a medication used to treat parasites in horses can fight deadly staph infections. It’s a promising new approach to solving the problem of antibiotic resistance.

The ability to modify multiple genetic elements simultaneously would help to elucidate and control the gene interactions and networks underlying complex cellular functions. However, current genome engineering technologies are limited in both the number and the type of perturbations that can be performed simultaneously. Here, we demonstrate that both Cas12a and a clustered regularly interspaced short palindromic repeat (CRISPR) array can be encoded in a single transcript by adding a stabilizer tertiary RNA structure. By leveraging this system, we illustrate constitutive, conditional, inducible, orthogonal and multiplexed genome engineering of endogenous targets using up to 25 individual CRISPR RNAs delivered on a single plasmid. Our method provides a powerful platform to investigate and orchestrate the sophisticated genetic programs underlying complex cell behaviors.
