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 and director of Columbia’s Irving Institute for Clinical and Translational Research.

Dr. Melvin Vopson’s study delves into the intriguing concept of information entropy, which differs from traditional physical entropy. Physical entropy measures the disorder within a system’s physical states, whereas information entropy pertains to the arrangement and complexity of information within those states.

Vopson applied this principle to the SARS-CoV-2 virus, analyzing its mutations through an information entropy lens. He explained, “The physical entropy of a given system is a measure of all its possible physical microstates compatible with the macrostate…the additional entropy associated with them is called the entropy of information.”

Scientists have, for the first time ever, made light appear to move simultaneously forward and backward in time.

According to a LiveScience report, the new approach, developed by a global team of scientists, may contribute to the development of novel quantum computing methods and advance our understanding of quantum gravity.

In a pioneering achievement, a research team led by experts at Cincinnati Children’s have developed the world’s first human mini-brain that incorporates a fully functional blood-brain barrier (BBB).

This major advance, published May 15, 2024, in Cell Stem Cell, promises to accelerate the understanding and improved treatment of a wide range of brain disorders, including stroke, cerebral vascular disorders, brain cancer, Alzheimer’s disease, Huntington disease, Parkinson’s disease, and other neurodegenerative conditions.

“Lack of an authentic human BBB model has been a major hurdle in studying neurological diseases,” says lead corresponding author Ziyuan Guo, PhD, “Our breakthrough involves the generation of human BBB organoids from human pluripotent stem cells, mimicking human neurovascular development to produce a faithful representation of the barrier in growing, functioning brain tissue. This is an important advance because animal models we currently use in research do not accurately reflect human brain development and BBB functionality.”

Memristors mimic timekeeping in the brain, which is done with neurons that relax at different rates after receiving a signal.

Leading AI scientists are calling for stronger action on AI risks from world leaders, warning that progress has been insufficient since the first AI Safety Summit in Bletchley Park six months ago.

In the fascinating realm of quantum physics, particles seem to defy the laws of classical mechanics, exhibiting mind-bending phenomena that challenge our understanding of the universe. One such phenomenon is quantum tunneling.

In quantum tunnels, particles appear to move faster than the speed of light, seemingly breaking the fundamental rules set by Einstein’s theory of relativity.

However, a group of physicists from TU Darmstadt has proposed a new method to measure the time it takes for particles to tunnel, suggesting that previous experiments may have been inaccurate.

SpaceX’s Starlink has expanded its satellite internet coverage to include the entire US and announced an upcoming ‘Direct to Cell’ service.

The Low Power Double Data Rate 6 (LPDDR6) memory may be introduced with data rates starting from 10.667 Gbps and bandwidth of 32 Gbps. This is the new information coming from the JEDEC presentation, as revealed by Synopsys and published Darkmont. The presentation touches on several topics, including LPDDR, DDR and CAMM standards.

The LPDDR5 standard is already 5 years old, it is time for an update. The mid-product update from Samsung and SK Hynix in a form of LPDDR5X and LPDDR5T are not good enough anymore and in 1–2 years demand for higher bandwidth will unquestionable. Especially given the progress in integrated graphics solutions, which heavily rely on fast system memory.
