Why can’t humans regenerate body parts? We’ve got the genes

Posted by in categories: biotech/medical, life extension

Some of our closest invertebrate cousins, like this Acorn worm, have the ability to perfectly regenerate any part of their body that’s cut off — including the head and nervous system. Humans have most of the same genes, so scientists are trying to work out whether human regeneration is possible, too.

Regeneration – now that’d be a nice superpower to have. Injure an arm? Chop it off and wait for it to grow back. Dicky knee? Ingrown toenail? Lop off your leg and get two for one!

It sounds ridiculous, but there’s a growing number of scientists that believe body part regeneration is not only possible, but achievable in humans. After all, not only are there plenty of animals that can do it, we can do it ourselves for our skin, nails, and bits of other organs.

The Signals in Your Brain that Tell You When It’s Time to Move

Posted by in category: robotics/AI

A new study, published in “Nature Communications” this week, led by Jake Gavenas PhD, while he was a PhD student at the Brain Institute at Chapman University, and co-authored by two faculty members of the Brain Institute, Uri Maoz and Aaron Schurger, examines how the brain initiates spontaneous actions. In addition to demonstrating how spontaneous action emerges without environmental input, this study has implications for the origins of slow ramping of neural activity before movement onset—a commonly-observed but poorly understood phenomenon.

In their study, Gavenas and colleagues propose an answer to that question. They simulated spontaneous activity in simple neural networks and compared this simulated activity to intracortical recordings of humans when they moved spontaneously. The study results suggest something striking: many rapidly fluctuating neurons can interact in a network to give rise to very slow fluctuations at the level of the population.

Imagine, for example, standing atop a high-dive platform and trying to summon the willpower to jump. Nothing in the outside world tells you when to jump; that decision comes from within. At some point you experience deciding to jump and then you jump. In the background, your brain (or, more specifically, your motor cortex) sends electrical signals that cause carefully coordinated muscle contractions across your body, resulting in you running and jumping. But where in the brain do these signals originate, and how do they relate to the conscious experience of willing your body to move?

The Internet Archive Loses Its Appeal of a Major Copyright Case

Posted by in categories: biotech/medical, internet, law

The Internet Archive has lost a major legal battle—in a decision that could have a significant impact on the future of internet history. Today, the US Court of Appeals for the Second Circuit ruled against the long-running digital archive, upholding an earlier ruling in Hachette v. Internet Archive that found that one of the Internet Archive’s book digitization projects violated copyright law.

Notably, the appeals court’s ruling rejects the Internet Archive’s argument that its lending practices were shielded by the fair use doctrine, which permits for copyright infringement in certain circumstances, calling it “unpersuasive.”

In March 2020, the Internet Archive, a San Francisco-based nonprofit, launched a program called the National Emergency Library, or NEL. Library closures caused by the pandemic had left students, researchers, and readers unable to access millions of books, and the Internet Archive has said it was responding to calls from regular people and other librarians to help those at home get access to the books they needed.

AI-Assisted Police Reports and the Challenge of Generative Suspicion

Posted by in categories: law, robotics/AI

This article delves into a transformative shift in the criminal justice system brought on by the use of AI-assisted police reports.


Police reports play a central role in the criminal justice system. Many times, police reports exist as the only official memorialization of what happened during an incident, shaping probable cause determinations, pretrial detention decisions, motions to suppress, plea bargains, and trial strategy. For over a century, human police officers wrote the factual narratives that shaped the trajectory of individual cases and organized the entire legal system.

All that is about to change with the creation of AI-assisted police reports. Today, with the click of a button, generative AI Large Language Models (LLMS) using predictive text capabilities can turn the audio feed of a police-worn body camera into a pre-written draft police report. Police officers then fill-in-the blanks of inserts and details like a “Mad Libs” of suspicion and submit the edited version as the official narrative of an incident.

Common yellow food dye can make the skin of a mouse temporarily transparent, study finds

Posted by in categories: biotech/medical, food, health

In H.G. Wells’ 1,897 science fiction novel, “The Invisible Man,” the protagonist invents a serum that makes the cells in his body transparent by controlling how they bend light.

More than 100 years later, scientists have discovered a real-life version of the substance: A commonly used food coloring can make the skin of a mouse temporarily transparent, allowing scientists to see its organs function, according to a new study published Thursday in the journal Science.

The breakthrough could revolutionize biomedical research and, should it be successfully tested in humans, have wide-ranging applications in medicine and health care, such as making veins more visible to draw blood.

100-fold Improvement in Sight Seen After Gene Therapy Trial

Posted by in categories: biotech/medical, genetics

The vision of people with a rare inherited condition that causes them to lose much of their sight early in childhood was 100 times better after they received gene therapy to address the genetic mutation causing it. Some patients even experienced a 10,000-fold improvement in their vision after receiving the highest dose of the therapy, according to researchers from the Perelman School of Medicine at the University of Pennsylvania who co-led the clinical trial published in The Lancet.

“That 10,000-fold improvement is the same as a patient being able to see their surroundings on a moonlit night outdoors as opposed to requiring bright indoor lighting before treatment,” said the study’s lead author, Artur Cideciyan, Ph.D., a research professor of Ophthalmology and co-director of the Center for Hereditary Retinal Degenerations.

“One patient reported for the first time being able to navigate at midnight outdoors only with the light of a bonfire.”
