Artificial neurons may repair damaged cells and circuits

Posted by in categories: biotech/medical, chemistry, robotics/AI

Electronic neurons made from silicon mimic brain cells and could be used to treat autism1.

Researchers plan to use the technology in conjunction with machine learning to retrain damaged or atypical neurons and restore function in the brains of people with Alzheimer’s disease, autism or other conditions.

Another team attempted to make artificial neurons in 2015 from a conductive organic chemical, but that version oversimplified brain signaling and was too large to implant in a human brain2.

Breaking bonds: Double-helix unzipping reveals DNA physics

Posted by in categories: biotech/medical, computing

Accurately reconstructing how the parts of a complex molecular are held together knowing only how the molecule distorts and breaks up—this was the challenge taken on by a research team led by SISSA’s Cristian Micheletti and recently published on Physical Review Letters. In particular, the scientists studied how a DNA double helix unzips when translocated at high velocity through a nanopore, reconstructing fundamental DNA thermodynamic properties from the sole speed of the process.

The translocation of polymers through nanopores has long studied as a fundamental theoretical problem as well as for its several practical ramifications, e.g. for genome sequencing. We recall that the latter involves driving a DNA filament through a pore so narrow that only one of the double-helical strands can pass, while the other strand is left behind. As a result, the translocated DNA will necessarily split and unwind, an effect known as unzipping.

The research team, which also includes Antonio Suma from the University of Bari, first author, and Vincenzo Carnevale from Temple University, used a cluster of computers to simulate the process with different driving forces keeping track of the DNA’s unzipping speed, a type of data that has rarely been studied despite being directly accessible in experiments.

Job listing platform Indeed lays off 2,200 employees

Posted by in categories: biotech/medical, employment

At a company that helps people find jobs, 2,200 employees will now have to embark on a job search of their own. Indeed laid off 15% of employees today, CEO Chris Hyams announced in an all-hands meeting.

In a blog post, Hyams elaborated on the decision by explaining that the job market is expected to continue to cool down. Indeed makes its money by allowing companies to sponsor job listings, which shows the listing to more job seekers. But Hyams said that as of last quarter, sponsored job volumes were down 33% year over year, and total job openings were down 3.5%.

“With future job openings at or below pre-pandemic levels, our organization is simply too big for what lies ahead,” Hyams wrote. “We have held out longer than many other companies, but the revenue trends are undeniable. So I have decided to act now.”

New DART VADAR system allows development of precision RNA-based therapies

Posted by in categories: biological, biotech/medical

DART VADAR can automatically sense and respond to molecular triggers in cells.

During the COVID-19 pandemic, the term mRNA was brought to the public’s attention. It is, however, not a new medical technology, having been identified in 1961.

These mRNA vaccines were developed to generate a full-body immune response in order to protect the human body from the deadly coronavirus and its variants.

New ‘biohybrid’ implant will restore function in paralyzed limbs

Posted by in categories: biotech/medical, neuroscience

“This interface could revolutionize the way we interact with technology.”

Researchers from the University of Cambridge have created a new type of neural implant that could restore limb function in paralyzed limbs.

There have been former attempts at using neural implants to restore limb function, but these mostly failed. This is because scar tissue can envelop the electrodes over time, disrupting the connection between the device and the nerve.

We’re one step closer to a meaty cyberpunk future as scientists create a ‘living computer’ using 80,000 mouse brain cells

Posted by in categories: biotech/medical, robotics/AI

Scientists in the US managed to put together a living computer by cultivating over 80,000 mouse stem cells (opens in new tab) (via IT Home) (opens in new tab). One day, the hope is to have a robot that uses living muscle tissue to sense and process information about its environment.

Researchers at the University of Illinois have used tens of thousands of living mouse brain cells to build a computer that can recognize patterns of light and electricity. The team presented their findings at the American Institute of Physics in the form of a computer about the size of your palm.
