A leading neuroscientist claims that a pong-playing clump of about a million neurons is “sentient”. What does that mean? Why did Cortical Labs teach a lab-grown brain to play pong? To study biological self-organization at the root of life, intelligence, and consciousness. And, according to their website, “to see what happens.” What’s next for biocomputing?

It’s a mission that is less a nostalgic yearning for a prehistoric past than it is a solution to combat climate change, the company’s founders have said. By reintroducing mammoths to Arctic environments, they hope to rejuvenate grasslands and reduce permafrost thaw—a major source of methane emissions.

The potential ripple effects of such an ecological intervention have raised profound ethical and scientific questions but have nonetheless captivated researchers, investors and the public alike.

Engineered enzymes are poised to have transformative impacts across applications in energy, materials, biotechnology, and medicine. Recently, machine learning has emerged as a useful tool for enzyme engineering. Now, a team of bioengineers and synthetic biologists says they have developed a machine-learning guided platform that can design thousands of new enzymes, predict how they will behave in the real world, and test their performance across multiple chemical reactions.

Their results are published in Nature Communications in an article titled, “Accelerated enzyme engineering by machine-learning guided cell-free expression,” and led by researchers at Stanford University and Northwestern University.

“Enzyme engineering is limited by the challenge of rapidly generating and using large datasets of sequence-function relationships for predictive design,” the researchers wrote. “To address this challenge, we develop a machine learning (ML)-guided platform that integrates cell-free DNA assembly, cell-free gene expression, and functional assays to rapidly map fitness landscapes across protein sequence space and optimize enzymes for multiple, distinct chemical reactions.”

A new twist on a decades-old anticancer strategy has demonstrated significant potential against various cancer types in a preclinical study conducted by researchers at the Perelman School of Medicine at the University of Pennsylvania

The University of Pennsylvania (Penn) is a prestigious private Ivy League research university located in Philadelphia, Pennsylvania. Founded in 1740 by Benjamin Franklin, Penn is one of the oldest universities in the United States. It is renowned for its strong emphasis on interdisciplinary education and its professional schools, including the Wharton School, one of the leading business schools globally. The university offers a wide range of undergraduate, graduate, and professional programs across various fields such as law, medicine, engineering, and arts and sciences. Penn is also known for its significant contributions to research, innovative teaching methods, and active campus life, making it a hub of academic and extracurricular activity.

Novel magnetic nanodiscs could provide a much less invasive way of stimulating parts of the brain, paving the way for stimulation therapies without implants or genetic modification, MIT researchers report.

The scientists envision that the tiny discs, which are about 250 nanometers across (about 1/500 the width of a human hair), would be injected directly into the desired location in the brain. From there, they could be activated at any time simply by applying a magnetic field outside the body. The new particles could quickly find applications in biomedical research, and eventually, after sufficient testing, might be applied to clinical uses.

The development of these nanoparticles is described in the journal Nature Nanotechnology, in a paper by Polina Anikeeva, a professor in MIT’s departments of Materials Science and Engineering and Brain and Cognitive Sciences, graduate student Ye Ji Kim, and 17 others at MIT and in Germany.

As NASA’s Europa Clipper embarks on its historic journey to Jupiter’s icy moon, Europa, Dr. Matt Powell-Palm, a faculty member at Texas A&M University’s J. Mike Walker ’66 Department of Mechanical Engineering, has unveiled groundbreaking research that could transform our understanding of icy ocean worlds across the solar system. The study published in Nature Communications, co-authored with planetary scientist Dr. Baptiste Journaux of the University of Washington, introduces a novel thermodynamic concept called the “centotectic” and investigates the stability of liquids in extreme conditions — critical information for determining the habitability of icy moons like Europa.

Revolutionizing the Search for Habitability.

The exploration of icy ocean worlds represents a new frontier in planetary science, focusing on understanding the potential for these environments to support life. Powell-Palm’s research addresses a fundamental question in this field: under what conditions can liquid water remain stable on these distant, frozen bodies? By defining and measuring the cenotectic, the absolute lowest temperature at which a liquid remains stable under varying pressures and concentrations, the team provides a critical framework for interpreting data from planetary exploration efforts.

+ Decoding the secrets of DNA, CRISPR gene editing allows scientists to target specific genes linked to aging. By modifying these genes, researchers aim to prevent conditions that come with aging. Envision a future where genetic risks for age-related diseases are minimized through precise DNA editing.

It is possible to regenerate cells using stem cells, which can turn into a variety of types. In recent trials, stem cells showed promise in regenerating aged tissues like cartilage. Scientists hope to develop therapies that might slow down physical decline and maintain vitality longer by using this potential.

Nanobots could someday be the future of healthcare by targeting damaged cells directly as they move through your bloodstream. Researchers are currently exploring how nanobots might repair cellular damage and improve overall health, potentially reversing some age-related effects at the cellular level.

As the protective ends of chromosomes, telomeres shorten over time. When they become too short, cells stop functioning. In laboratory studies, researchers have extended the lifespan of animals by using telomere extension techniques. Though still experimental, this research could pave the way for human applications in slowing aging.
