Clogged Arteries Worsened by Cells that Behave like Cancer Cells

Columbia University researchers have found cells inside clogged arteries share similarities with cancer and aggravate atherosclerosis, raising the possibility that anticancer drugs could be used to treat atherosclerosis and prevent heart attacks.

Their study found that smooth muscle cells that normally line the inside of our arteries migrate into atherosclerotic plaques, change their cell identity, activate cancer genes, and proliferate inside the plaques.

“Our study shows that these transformed muscle cells are driving atherosclerosis, opening the door to new ways to treat the disease, potentially with existing cancer drugs,” says Muredach Reilly, MD, the Florence and Herbert Irving Endowed Professor of Medicine at Columbia University Vagelos College of Physicians and Surgeons ...

A research team has created an innovative method to control tiny magnetic states within ultrathin, two-dimensional van der Waals magnets — a process akin to how flipping a light switch controls a bulb. Imagine a future where computers can learn and make decisions in ways that mimic human thinking, but at a speed and efficiency that are orders of magnitude greater than the current capability of computers.

A research team at the University of Wyoming created an innovative method to control tiny magnetic states within ultrathin, two-dimensional (2D) van der Waals magnets — a process akin to how flipping a light switch controls a bulb.

“Our discovery could lead to advanced memory devices that store more data and consume less power or enable the development of entirely new t...

NASA recently asked the scientific community to help come up with innovative ideas for ways to carry out its Mars Sample Return (MSR) mission. This was in response to a report by an independent board that deemed that its US$11 billion (£8.7 billion) price tag was too expensive and its 2040 timeline too far in the future.

In brief, the ambitious plan was to collect rock samples cached inside containers by NASA’s Perseverance rover and deliver them to laboratories on Earth. Perseverance has been exploring Mars’ Jezero Crater, thought to have once hosted an ancient lake, since 2021...

AI Speech Analysis may aid in Assessing and Preventing Potential Suicides, says researcher

Speech is critical to detecting suicidal ideation and a key to understanding the mental and emotional state of people experiencing it. Suicide hotline counselors are trained to quickly analyze speech variation to better help callers through a crisis.

But just as no system is perfect, there is room for error in interpreting a caller’s speech. In order to assist hotline counselors to properly assess a caller’s condition, Concordia Ph.D. student Alaa Nfissi has developed a model for speech emotion recognition (SER) using artificial intelligence tools. The model analyzes and codes waveform modulations in callers’ voices. This model, he says, can lead to improved responder performance in real-life suicide monitoring.

The research is published as part ...
